氢气检测仪安全操作及保养规程

氢气检测仪安全操作及保养规程

氢气检测仪安全操作及保养规程摘要随着氢能技术的不断发展,氢气作为一种新型能源被广泛应用。

但氢气的易燃、易爆性质给氢气设备的安全带来了威胁。

本文在介绍氢气检测仪的基本原理和使用方法的基础上,通过分析危险因素,提出了氢气检测仪的安全操作和保养规程,以期为使用氢气检测仪的人员提供一定的参考。

氢气检测仪简介氢气检测仪是一种用于检测氢气浓度的专业设备。

它主要由传感器、信号处理器和显示器等组成。

传感器通过检测氢气浓度将氢气浓度转换成电信号,并通过信号处理器将电信号转换成数字信号,然后通过显示器显示氢气浓度值和报警信息。

氢气检测仪主要应用于氢气储运、加注站和工业生产等领域,用于检测氢气浓度,确保操作人员的安全。

在氢气设备的生产、运输和使用过程中,氢气检测仪是必不可少的安全设备之一。

使用方法氢气检测仪的使用方法如下:•准备工作:将氢气检测仪放置在测试区域,并将电源插头插入插座。

•开机操作:按下开机按钮,开机。

设备启动后,应等待一段时间,直至设备正常工作。

•测量操作:将检测仪导管接入氢气管路,并使其直接暴露于氢气环境中,等待数秒后即可得到氢气浓度值。

•关机操作:测量完毕后,按下关机按钮即可关闭设备。

注意:在整个操作过程中,务必保持设备与氢气管线的密封性,禁止在检测区域内吸烟、使用明火等行为。

安全注意事项虽然氢气检测仪是一种专业安全设备,但在实际操作中仍然需要注意以下几点:1. 避免设备受损在使用过程中,要避免检测仪受到机械撞击、过热、大力振动等损坏因素的影响,以免影响测试结果。

2. 避免设备进水氢气检测仪是电器设备,应避免进水,以免引起漏电等危险。

在使用过程中,应将设备放置在干燥、通风的环境中,不要将设备用于潮湿的场所。

3. 避免设备超载氢气检测仪的传感器灵敏度有限,过高的氢气浓度会导致系统超载,进而导致检测结果不准确,因此在使用过程中,应做好预先调整好灵敏度并避免氢气浓度过高。

4. 避免误判在操作过程中,应尽量避免其他气体的干扰,以免误判氢气的浓度。

CO检测报警仪、可燃气体测爆仪及氢气检漏仪的使用方法

CO检测报警仪、可燃气体测爆仪及氢气检漏仪的使用方法

CO气体检测报警仪、可燃气体测爆仪及氢气检漏仪的使用方法一、一氧化碳气体检测报警仪(简称CO测报仪)1、一氧化碳气体检测报警仪的测定范围是CO含量0—2000PPM,开始声响报警范围为0—300PPM可调,一般调整到CO含量达到50PPM开始报警;2、焦炉煤气与空气混合时的爆炸浓度范围是:混合物中焦炉煤气含量4.7—38%。

即爆炸下限为4.7%,混合物中焦炉煤气含量低于4.7%不会爆炸;爆炸上限为38%,混合物中焦炉煤气含量高于38%不会爆炸;3、焦炉煤气中CO的含量在7%左右,即其中CO含量为70000PPM。

当焦炉煤气与空气混合时,如焦炉煤气含量为4.7%,则混合物中CO含量应为:70000×4.7%=3290PPM 。

如混合物中CO含量为200PPM,则其中焦炉煤气含量应为:200/70000=0.286%;4、焦炉煤气与空气的混合物中,焦炉煤气含量为4.7%时,混合物中CO含量为70000×4.7%=3290PPM,大于一氧化碳气体检测报警仪的测定范围———2000PPM。

所以一氧化碳气体检测报警仪的主要作用是防止CO中毒,而不是测定气体是否会爆炸。

但是对于焦炉煤气与空气的混合物来说,如果其中CO含量低于2000PPM的话,它肯定低于爆炸下限,所以一氧化碳气体检测报警仪在一定条件下可以用来确定可燃气体混合物是否能够爆炸(对于液化石油气就不行);5、一氧化碳气体检测报警仪不可长期工作在CO含量较高的条件下,以免仪器中毒失灵。

二、可燃性气体检测报警仪(简称“测爆仪”)1、测爆仪能检测空气中可燃气体爆炸下限浓度的百分比含量,其测定范围是爆炸下限浓度的0—100%,开始声响报警范围为爆炸下限浓度的5—60%可调,一般调整到爆炸下限浓度25%开始报警;2、焦炉煤气与空气混合物的爆炸下限为4.7%,这相当于爆炸下限浓度的100%。

由此可知,当测爆仪上的指字为15%时,混合物中含焦炉煤气为:4.7%×15%=0.705%三、氢气检漏仪⑴SQJ—ⅠA型1、SQJ—ⅠA型氢气检漏仪能检测空气中氢气爆炸下限浓度的百分比含量,其检测范围是爆炸下限浓度的0—100%,氢气与空气混合物的爆炸下限为4%,如果按ppm计,其检测范围是0~40000ppm。

During this time the LCD displays a countdown to completion and the Probe Tip LED is amber. The following operations occur:The Wide Range Sensor® reaches operating temperature.A system self-test is run.Upon successful completion of the above tasks the instrument zeroes itself and automatically switches to normal operation. If an error is detected theinstrument will display an error code (see Section 10).3.2ShutdownTo power-down the HY-ALERTA™ 500, press and hold the ON/OFF button forapproximately two seconds until the Controller LCD display turns off.3.3Battery LevelAfter power-on the BATTERY LED indicates the current battery level (times areapproximate and may vary as the battery ages):Color MeaningGreen more than 60 minutes of operation remainingAmber approximately 15 to 60 minutes of operation remainingRed less than approximately 15 minutes of operation remainingA fully charged battery should last 10 to15 hours, depending on use.There is a small load on the battery when the unit is powered off. This load will discharge the battery of the unit in it’s powered off state in about 6 months.Customers that do not use the device frequently should charge the batteryand perform a bump test with hydrogen gas every one to three months tokeep the battery charged and ready for use.3.4Normal OperationDuring normal operation the instrument is detecting and reporting thehydrogen concentration near the probe tip sensor. Hydrogen readings aredisplayed on the controller LCD and the probe tip LED bar graph array. Note that due to the extreme sensitivity of the sensor, it may take several minutes to return to a near zero (less than 0.001%) reading after exposure to hydrogen. If the instrument does not return to an indication of less than 0.001% after 5minutes in a hydrogen-free environment, then invoke the Reset operation (See Section 3.6).The upper line of the Controller LCD indicates a numerical value or range for the percent hydrogen concentration or peak hydrogen value. The lower line is used to display the hydrogen meter, a logarithmic bar graph ranging from0.001% (10 ppm) to 100% hydrogen by volume. An open box on the bar indicates the last peak value obtained and filled boxes indicate the current value. The following figure describes how to interpret the hydrogen meter:The Probe Tip LED Indicator shows an increase or decrease in hydrogenconcentration. Leak detection is accomplished by watching the Probe Tip LED and the bar graph array and moving the sensor around a potential hydrogen leak.The number of yellow LEDs lit in the Probe LED bar graph array indicates detected hydrogen concentrations in four ranges as noted below:3.5Hydrogen-Free AreasFor the purposes of this document a hydrogen-free area is one with less than5ppm of hydrogen in the air.It may be difficult to find a hydrogen-free area in a facility where hydrogen is used. Nearby rooms, or even the entire building, may not be hydrogen free.To check these areas reset or zero the sensor outside, away from any hydrogen tanks, pipes, or other potential sources. Walk through the facility, watching the sensor. It is surprising how far low levels of hydrogen can spread.If the sensor is zeroed or reset in hydrogen, there will be a negative offset in the readings that could compromise the sensor’s ability to find small leaks.3.6Reset OperationThe Reset Operation is used to speed recovery from hydrogen exposure.It can be invoked from the keypad while in the top menu level (measuring hydrogen) by pressing and holding ◄►(left and right arrow buttons simultaneously) or from the Reset Menu (see Section 4). Once invoked the user is asked to confirm the operation by pressing the ENTER key. Pressing any other key will abort the operation. During Reset the LCD indicates a count down to completion and the Probe tip LED is yellow.3.7Zero OperationThe Zero Operation is used to zero the hydrogen reading if the instrument is reporting low levels (0.001% to 0.01%) of hydrogen when no hydrogen is present. This operation can be invoked from the keypad while in the top menu level (measuring hydrogen) by pressing and holding ◄ (left arrow button) or from the Reset Menu (see Section 4). Once invoked the user is asked to confirm the operation by pressing the ENTER key, pressing any other key will abort the operation.4.

Understanding this behavior allowsa more effective search for hydrogen leaks.The hydrogen plume from a leak generally spreads in a roughly conical shape that is easily disturbed by environmental conditions. Certain conditions such as pressure, temperature, and leak size may act together to change the shape of the hydrogen plume from a cone to a laser-like beam. This makes finding aleak more difficult.If the sensor element is near (and above) the leak, the concentration will likely be higher but the leak may be difficult to locate. As hydrogen dissipates theconcentration decreases. Generally, greater distances will increase thechance of intercepting the leak stream, but if the sensor is too far away, theresponse may be too weak to detect.When drafts or air currents are present, hydrogen will tend to be dispersed.Testing for hydrogen leaks downwind of the leak area may increase thechance of detecting the leak.If hydrogen is rising in an enclosed building the hot air near the ceiling mayslow the hydrogen’s rise. Thus, sensing hydrogen near ceiling areas with hightemperatures present may not be as effective as at a lower level.Low temperatures can also affect the behavior of hydrogen. Hydrogen stored in a liquid state is at an extremely low temperature. The low temperature ofany escaping hydrogen will be of a higher than normal density and mayinitially move downward. As the hydrogen warms, it will begin to rise upward.When checking for a leak in areas where liquid hydrogen is stored, check both above and below the area of concern.6.Bump TestA bump test is recommended every three months. The purpose of a bump testis to verify that the sensor is active, detecting hydrogen and verifying that the sensor is within the pre-set factory tolerance for accuracy. To performs a bump test perform the following:In a non-hydrogen environment, power on the instrument. Once theinstrument has gone through its standard 10 minute warm-up, use thecalibration cup that accompanies the HY-ALERTA™ Model 500, and apply 2% hydrogen to the probe sensor. Let the 2% hydrogen flow for a minimum of 3-5 minutes. After 3-5 minutes the concentration value registered on the LCDdisplay should read between 1.6% to 2.4%, which is within factory tolerance. If the 2% reading is below 1.6% or above 2.4% the instrument should go through a Verification test as outlined below.7.VerificationVerification is performed in a non-hydrogen environment to confirm that theHY-ALERTA™ Model 500 is operating properly and within the pre-set factorytolerance for calibration. The recommended verification interval is every 12months, or after a 2% bump test has been performed and the indicated values on the LCD display were outside the stated tolerance as outlined in Section 6.If the verification fails, then it should be repeated one more time.The HY-ALERTA Model 500 requires calibration only if it fails the secondverification. It cannot be field calibrated and must be returned to h2Scan for calibration service. An optional NIST traceable certificate is available uponrequest.7.1GasesVerification requires the availability of the following certified gases:2.00% hydrogen by volume in air (20,000 ppm)0.10% hydrogen by volume in air (1000 ppm)Zero grade, hydrogen-free air. Ambient air can be substituted if it ishydrogen-free.7.2Gas ConnectionGases are applied to the unit through the use of the Calibration Cup Assy. (P/N 50000009) available from H2Scan.7.3Verification KitsCustomer-specific Field Verification Kits for the HY-ALERTA™ 500 are available from H2scan.The field verification function allows the user to check the instrument’s calibration. Details on this function can be found in Table 1 on page 19. If the unit passes verification, calibration is not required at this time.If the unit fails verification, the unit should be returned to the factory for calibration.8.Battery ChargingEnsure the unit is powered OFF.Disconnect the coiled cord from the controller.Connect the battery charger to the controller.Using the appropriate A/C plug adapter for the region of use, plug the battery charger into the A/C supply.The battery charger indicator light will illuminate according to charge status as follows:Off No BatteryFlashing Green Fast chargingSteady Green Fully chargedSteady Amber StandbyFlashing Red ErrorNOTE: Complete charging may take up to 4 hours for a fully dischargedbattery.9.CleaningIf the unit becomes soiled, clean the unit with a lint-free cloth.

氢气报警仪量程国际标准

氢气报警仪量程国际标准

氢气报警仪量程国际标准一、量程范围根据国际标准,氢气报警仪的量程范围通常为0-100%氢气浓度。

这个范围可以满足大多数应用场景的需求,从低浓度氢气泄漏到高浓度氢气环境都可以进行检测。

二、精度要求氢气报警仪的精度要求通常为±5%满量程,也就是说,对于100%满量程的氢气浓度,报警仪的测量值应该在95%-105%之间。

这样可以保证测量结果的可靠性,降低误报和漏报的可能性。

三、响应时间响应时间是氢气报警仪的重要性能指标之一。

根据国际标准,氢气报警仪的响应时间应该小于30秒。

也就是说,当氢气浓度发生变化时,报警仪应该能够在30秒内做出反应,并及时发出报警信号。

四、温度和湿度范围氢气报警仪的工作环境温度通常为-20℃-50℃,相对湿度为0-95%。

在这个范围内,报警仪可以正常工作,并保证测量结果的准确性。

五、防爆等级由于氢气具有易燃易爆的特性,因此氢气报警仪必须具备防爆功能。

根据国际标准,氢气报警仪的防爆等级应该达到Exd II CT6 Gb级别,以防止在氢气泄漏时发生爆炸事故。

六、电源要求氢气报警仪的电源要求通常为直流24V或者交流220V,具体根据不同的型号和规格而定。

在电源方面,报警仪应该具备过压、欠压保护功能,以保证设备的稳定运行。

七、显示和报警功能氢气报警仪应该具备实时浓度显示功能,同时当氢气浓度超过预设的报警值时,能够发出声光报警信号,并具有故障自诊断功能。

此外,为了方便用户使用和管理,报警仪还应该具备数据存储和通讯功能,可以通过RS485、RS232或者CAN总线等方式与计算机或DCS系统进行连接。

八、维护和校准为了确保氢气报警仪的准确性和可靠性,应该定期进行维护和校准。

根据不同的使用情况和要求,可以设定不同的维护和校准周期。

在进行维护和校准时,应该按照相关标准和规范进行操作,同时选用合适的校准气体和设备。

在维护和校准过程中,应该注意安全问题,防止气体泄漏等安全事故的发生。

2024年可燃气体报警器使用注意事项(三篇)

2024年可燃气体报警器使用注意事项(三篇)

2024年可燃气体报警器使用注意事项为了使可燃气体报警器正常工作,有效发挥其预警作用,安装、使用过程中应注意以下几个方面:1.安装报警回路时应注意的问题(1)报警器的周围不能有对仪表工作有影响的强电磁场(如大功率电机、变压器等),如果无法避开,应采取屏蔽措施。

(2)报警显示仪是安全仪表,有声、光显示功能,应安装在工作人员易看到听到的地方,以便及时了解情况。

(3)报警显示仪安装高度一般在1.6~1.7m为宜,便于维修人员对报警器进行日常修理和维护工作。

2.探头的安装应注意的问题(1)探头主要是用接触燃烧气敏传感器(也称热线式传感器)的检测元件,该元件是由铂丝线圈上包氧化铝和粘合剂组成球状,其上表面附有铂、钯等稀有金属。

安装时一定要轻拿、轻放,以免摔坏探头。

(2)被测气体的比重不同,探头的安装位置也不同。

室内探头的安装:被测气体的密度小于空气的密度时,应安装在距屋顶30cm处,探头向下;反之,被测气体的密度大于空气密度时,探头要安装在距地面30cm处。

(3)露天探头的安装:可根据被测气体的密度情况选择安装高度。

特别应注意,探头要装在下风侧。

(4)探头应安装在可能泄露点附近,且尽可能接近。

特别是可燃气体易积聚的死角(地坑、排污沟等),一定要安装探头,并要避免风直接吹探头。

(5)连接电缆要穿保护套管。

在探头的接线处加金属软管,并注意防爆标志等级与工厂防爆要求一致。

(6)安装调试后,一定要装透气防水罩,以防雨水进入探头而损坏。

透气防水罩要定期取下清洗,保证可燃气体正常扩散进入探头。

3.校验时应注意的问题(1)要采用经计量认证的与被监测气体相匹配的标准样气。

不同的测量介质,所选的标准样气不同,报警点也不同。

(2)校验前,探头的周围环境中应无可燃气体。

若有,先拆下防雨罩,充入一定量的洁净空气,调整好零点后,再连续通入样气,以保证校验的准确性。

(3)当被测气体为烃类混合物时,异丁烷为首选样气,其次为丙烷。

(4)对于被检测可燃气体组分复杂或不易得到相对应的标准样气的可燃气体,可使用:丁烷、异丁烷、丙烯等既易得又稳定的单组分燃气作为检定样气。

氢气检测仪选型说明及注意事项

氢气检测仪选型说明及注意事项

一、概述:目前,各种气体燃料如天然气、液化石油气、城市煤气广泛地应用在家庭、工业场所,在的人们日常生活和工业生产带来方便的同时,也伴随着各种各样的安全隐患。

通常,可燃气体报警器报警点设置为被检测可燃气体爆炸下限的1%--25%范围内。

例如对于氢气,它的爆炸下限为4%,即4%=100%LEL=40000ppm, 相应氢气报警器的报警点范围应在1%LEL – 25%LEL之间,即0.04%(400ppm)—0.1%(10000ppm);若想增大安全系数,也可设定为1000ppm(0.01%).但是,一味地追求高灵敏度而降低报警设定点将会导致报警器的抗干扰能力变差,无危险的微量泄漏及环境温湿度或气氛的变化均会导致报警器的误报警,从而降低了报警系统的准确性、可靠性,这也是设定报警点时必须注意的。

一般氢气低限125PPM-750PPM 与上述不同的是,由于人工煤气含有高毒性的一氧化碳,毫无爆炸危险的少量泄漏即可引起致命的中毒事故,预防中毒往往成为人工煤气报警器监测泄漏的首要作用,报警点的设置应该充分考虑人工煤气的一氧化碳含量,将报警点设置于相当一氧化碳50PPM-300PPM的浓度范围。

二、检测原理:毒气/氧气检测仪器工作原理:传感器通常由三个电极构成,其中最主要的是工作电极。

它通常是用一种具有催化活性的金属,将其喷镀在一种透气但是憎水的膜上做成。

被测量的气体扩散透过多孔的膜在其上进行氧化或还原反应。

其反应的性质以工作电极的热力学电位和分析气体的氧化还原性质而定。

氧化还原反应中参加反应的电子,流向(还原)或流出(氧化)工作电极,通过外电路成为传感器的输出信号。

可燃气体检测仪工作原理:仪器所采用传感器是由两种传感器元件组成,一种为检测元件,另一种为补偿元件,两种元件都具有电热效应,分别构成电桥的两个桥臂。

当气体接触到传感器时,检测元件开始催化燃烧,补偿元件保持不变,因而电桥的桥臂阻值发生变化,产生一个失衡电压。

安装方式:
气体检测报警器安装方式有抱管安装、墙壁安装、支架固定安装等方式。

气体检测报警器的具体安装位置是由气体的比重决定的,具体安装方案如下:
气体检测报警器的安装位置是根据GB50493-2009《石油化工易燃气体和有害气体检测报警设计规范》相关规定依据检测气体密度及风向确定气体检测报警器安装位置。

报警器宜布置在可燃气体或有毒气体释放源的最小频率风向的上风侧。

可燃气体报警器的有效覆盖水平平面半径,室内宜为7.5m ;室外宜为15m 。

有毒气体报警器与释放源的距离,室外不宜大于2m,室内不宜大于1m 。

需设置易燃气体或有毒气体报警器的场所,宜采用固定式,当不具备设置固定式的条件时,应配置便携式检测报警器。

检测器宜安装在无冲击、无振动、无强电磁场干扰的场所,且周围留有不小于0.3m 的净空。

检测比空气重气体报警器安装高度应距面0.3~0.6m ;检测比空气轻气体报警器安装高度宜高释放源0.5~2m
说明:气体密度于0.97kg/m3(标准状态)即认比空气重,气体密度于0.97kg/m3(标准状态)即认比空气轻。
