空气循环干燥装置说明书
空气循环干燥装置说明书随着电力工业的发展,发电机组容量不断增大,离相封闭母线在电厂中也随之得到越来越多的应用。
多年以来,离相封闭母线以其安装简便、运行维护工作量小、钢结构发热少等特点受到用户的欢迎。
与此同时,由于离相封闭母线是一种密闭管道 , 当运行条件改变(如停机)或气候条件变化(如湿度大)时,其内部容易产生结露现象,从而降低母线的绝缘性能,甚至可能诱发单相接地事故,给电厂的安全运行带来隐患。
为了解决离相封闭母线的结露问题,国内最早也是目前最普遍采用的是微正压装置,但由于密封件老化或检修等原因,运行时间一长,很多母线内部无法建立微正压,因而也就不能达到长期有效驱潮的目的。
后来又出现了热风保养装置,其对母线的密封要求不如微正压装置高,但又带来了耗电量大的缺点(一般功率在二、三十千瓦)。
我厂是生产各种封闭母线的专业厂家,在对市场进行充分调研的基础上,综合微正压装置和热风保养装置的优点,自行开发出了空气循环干燥装置。
一、工作原理本装置采用闭式循环方式。
空气循环干燥装置把封母内空气抽出,并从外界补入少量空气,又重新送入封母,如此周而复始,使母线内的水分越来越少,相对湿度不断降低,露点温度也随之下降,从而保证封闭母线的安全可靠运行。
本装置的动力部分采用质量可靠的罗茨风机,它能比较迅速地循环干燥封闭母线中的空气。
电气部分采用 PLC 控制。
根据天气条件及运行情况,用户可选择工作模式为“手动”或“自动”。
采用“自动”模式时,按下控制面板“自动”按钮,“自动”运行模式开启,适用于空气湿度较低及机组正常运行时。
在这种模式下,温、湿度传感器或精密湿度监控器采集的母线内空气参数,与设定的露点温度值或相对湿度值进行比较。
当测量值大于设定值上限时,由PLC 控制本装置自动投入运行,运行满一个周期后再次检测母线内空气露点温度或相对湿度是否低于设定值下限,如果低于下限,则退出运行;否则继续运行一个周期,直至母线内空气参数值低于设定值下限则停机。
空气干燥器原理及器使用说明书
空气干燥器原理及器使用说明书-CAL-FENGHAI.-(YICAI)-Company One1空气干燥器使用说明书一用途:根据吸附原理对来自空压机的压缩空气进行干燥,它是通过冷却再生吸附对压缩空气的水分进行干燥的。
干燥筒内的粒状干燥剂具有很强的吸附空气中水分子的能力。
432 415系列的单缸干燥器带一个整体的回流截至阀,允许主储气筒的气通过回路保护阀回流,这样就不再需要单独的再生储气筒。
二原理在压力输入阶段,来自空压机的压缩空气经1口打开单向阀(i)进入A腔。
因温度降低产生的冷凝水在这里聚集,经通道C聚集出口(e)处。
经过安装在干燥筒中的精密滤网(g),环道(h),压缩空气到达干燥筒(b)上部,这个过程中,空气将进一步冷却,水蒸汽进一步凝结。
当通过颗粒状滤网时, ,水被吸附在粒状干燥剂表面及颗粒缝隙间。
[直径: 4 x 106 m = 4] .因为尺寸超过4的油粒子不能进入干燥剂颗粒缝隙.这使得干燥剂吸附性能稳定。
蒸发部分的油不被吸收.干燥后的空气经单向阀(c)和21口抵达贮气筒。
同时,干燥后的空气也进入E腔,膜片(O)压力增加,向右弯曲,通过孔(s)打开了E腔和G腔的通道,空气也通过滤网(I)进入H腔,阀(q)压力增加。
一旦克服了预调整的螺栓(r)保持的弹簧力,空气会到达F腔,作用在膜片(o)的另一边,以一个较低的气压保持阀(q)的开启状态。
由于G腔的压力下降,单向阀(c)关闭。
此时再生所需要的空气来自主回路储气筒,因此需要一个允许回流的回路保护阀。
21口的空气通过E腔、孔(s)到G腔,到达干燥罐(b)的底部。
空气从下向上经过干燥罐(b),吸附在干燥剂(a)表面的水分会经过排气口C和打开的排气阀门(e)排出。
当膜片(q)左侧的减小到关闭位置时,回流过程完成。
空气从E腔通过小孔到J腔,作用在膜片(m)上。
当克服弹簧力后,进气阀门(n)打开,活塞(d)下移打开排气阀(e)。
来自空压机的空气经过A腔、排气口C通过排气口3通大气。

Maintenance by the u serA) Keep the dryer clean.B) Regularly check the correct operation of the condensate drain trap.C) Every six months, check and clean the drain strainer by undoing the access screw and rinsing the filter with tap water to remove the trapped dirt from the inside.D) For air cooled dryers, clean the air condenser as soon as it’s dirty or clogged.E) For optional water-cooled condensers, use only clean water and install a water filter if needed.Use water counter flow to clean condenser if need.F) Check the trouble-shooting list in case of maintenance troubles.G) Check operating pressures, temperatures and time settings after maintenance. If operating and safety devices function properly, the air dryer may be used.A) Manufacturer:B) Purpose of this dryer1) This refrigerated compressed air dryer has been designed to remove water vapor from industrial compressed air.2) This dryer has been designed for indoor operation.3) The minimum and maximum values stated must be observed, as well as the safety precautions describedin this manual.The following label is affixed on the cabinetof the refrigerant compressed air dryer.D) Working details1) Refrigerant circuit:The refrigerant circuit can be divided in 3 parts:a) Low pressure section with an evaporator (heat exchanger)b) High-pressure section including: Condenser, liquid receiver, (if installed) and the filter dryer.c) Control circuit including: Compressor, Expansion valve, by-pass valve (if installed),Fan pressure switch (if installed)2) For water - cooled dryers:a) Water valveb) Safety high pressure switch (if installed)3) The Refrigerant circuit operates as follows:a) The compressor compresses gaseous refrigerant to a high temperature.b) The hot refrigerant condenses in the condenser. Being liquefied it is stored in the liquid receiver (if installed).c) The liquid is taken out the storage vessel and injected in the evaporator (heat exchanger) by an expansion valve. This expansion valve is protected by a filter, which removes particles and humidity that could be in the circuit. d) The injected liquid fills in the refrigerant section of the air / refrigerant heat exchanger and evaporates by taking out the calories from the compressed air. The gaseous refrigerant is sucked in the compressor and the cycle carries on.e) In order to keep the evaporation pressure steady, and thus the refrigerant temperature in the heat exchanger, a by-pass valve is injecting hot gaseous refrigerant in the circuit. On certain dryers, an automatic expansion valve regulates this.4) Compressed air circuita) The saturated hot compressed air flows into the Economiser where it is pre-cooled by the out flowing dry chilledair. In the cold zone of the air refrigerant section it continues to cooldown to dew point and enters the separator where condensates are collected. The outgoing chilled air is then warmed up in the economizer by the hot incoming air.b) The condensates are collected after centrifugal separation and drained out through the automatic trap.c) As long as the compressed air temperature does not drop below dew point, there will be no condensationin the air circuit.5) Refrigerant compressorBeing of the hermetic type, it requires no servicing.6) Condensera) Th e air condensers are equipped with a helecoidal at the condenser refrigerant level.On certain type of dryers, a water-cooled condenser can be fitted.b) In this case, a water valve being driven by the refrigerant circuit is taking care of its regulation.7) Refrigerant circuit protectiona) Klixon: The single phase compressors are equipped with a klixon which is a thermal sensitive switch controlling the temperature of the compressor and possible over intensity.In case of malfunction, the klixon trips but switches on again automatically as soon as the compressor has cooled down.b) High Pressure Security Switch: Refrigerant line is considered as a pressure vessel. That is why it is protected against bursts by the help of manually reset switch. It is set to 362.5 psi for dryers working with R134ac) Filter dryer: A refrigerant circuit is a closed circuit and total water removal in the refrigerant circuit is paramount in order to obtain a correct functioning.d) To avoid problems, the refrigerant circuit must be vacuumed before loading the refrigerant. It is equipped with a filter dryer, which also traps any solid particles, which may have migrated into the circuit during assembly.e) Water-cooled dryers have a safety high-pressure switch.In case of cooling water failure, the safety switch stops the dryer. When the safety switch has tripped out, it has to be manually resettled before switching on the dryer.8) Refrigerant circuit controlsa) Liquid refrigerant injection: The liquid refrigerant is into the evaporator by a control valve. This valve is a thermostatic or pressostatic one maintaining a constant overheats of the refrigerant in the evaporator(s).b) Constant evaporating pressure: In the dryers equipped with a by-pass valve, the evaporating pressure is kept constant by a controlled injection of hot gas from the high-pressure side into the low-pressure section of the circuit. 9) Condensate drain - trap assemblyDismantling the drain is easy because it can be isolated from the air circuit under pressure with a ball valve.The drain has to be depressurized before being dismantled.10) Heat Exchanger Modular designa) The dryers are equipped with a compact Mono Bloc Heat Exchangermodule. This assembly has been specially designed to dry compressed air and ismade of:1) An Economiser which pre-cools the entering hot air with the out flowing cold air.2) An air/refrigerant exchanger cooling down the compressed air.3) A centrifugal separator concentrating all condensates and requiring no maintenance.11) Accessoriesa) Dew point indicator: Located on the control panel, it displays the value of the pressure dew point.b) Temperature switch: Located inside the dryer, this temperature switch is adjustable from 32 °F up to 95 °Fc) Energy Saving Device: (ESD) This device helps dryer save energy when there is not any compressed air flowin the dryer. (Please see the models have standart and optional in next page)d) Filter change alarm on the front panel3.1. OperationA) Control panels: The control panel of the dryer includes the following elements:1) Dewpoint indicator (Standard) 2) Filter change Alarm** 3)Start / Stop B utton 1) Dewpoint indicator (Standard) 2) Start Light 3) N/A4) Filter change Alarm** 5) Main Switch1) ESD3 (Standard) 5) EMERGENCY STOPATTENTION : DN-US range dryers have low pressure drop according its competitors. Do not use DN-US range dryers together with other dryers which have higher pressure drop without getting the confirmation from our technical team.** IMPORTANT NOTE: The Dryer has two Compressed Air Filter inside.It is better to change filter element for the best efficiency when the alarm light is active. It is recommended to keep replacement filter elements in your stock in order to replace them when needed.153.2. During OperationRegularly check the digital temperature controller ESD3 or dew point indicator on dryer.B) Start up and shut-downWarning: Avoid leaving the dryer off when compressed air is still flowing through it.C) Starting for the first time or after a long stop1) Set the rotary switch to “I” This preheats the dryer and turns the drain system on.It is recommended to leave the dryer power on permanently so the crankcase heater runs continuously.3) Follow the daily starting and shut down procedure.D) Daily starting and shut-down1) Push on the green button to start the dryer.2) The start light will indicate that the dryer is running.3) To stop the dryer, first stop the airflow (either shut-down the air compressor or close the inlet/outlet orby-pass valve) When the air flow is stopped set the rotary switch on “ 0 “ Set it again on “ I “ in order to keep the preheating on.4) IMPORTANT NOTE!Avoid leaving the dryer stopped when compressed air is still flowing through it.5) To switch the already preheated dryer on again, simply push the green start button.E) Digital Temperature Control technical features (ESD3)ESD3: PLC clear text multilingual indication of alarms, maintenance and running hours+ Energy Saving Device automatic switching OFF at no load and ON when warm compressed air is entering.

打开(关闭)相应的电动阀门,阀门开闭到位后,启动罗茨风机,然后启动再生筒(B筒)内的加热器。
装置通过热电阻和数显仪监测、显示筒内的温度,当温度超过设定上限时,则加热器停止加热。
当温度降至设定下限时,则加热器重新加热。
排气口也设有测温元件,当排气温度超过设定时,则加热器在该周期内不再加热,B筒再生结束。
8h后,A、B筒互换,装置进入“B筒干燥吸附,A筒再生排气”程序,控制原理与上述类似。
16h后,一个循环工作周期结束,如湿度监控器测得母线内湿度低于设定下限时,则整套装置停止运行,否则,装置继续运行,进入下一个工作周期。
“手动”运行模式:手动运行模式只是通过“启动”和“停止”按钮人为给“PLC”发出启停信号,代替湿度监控器的接点信号,其他与“自动”运行模式完全一致。
无论“自动”还是“手动”运行模式,转换开关打到“停止”位置或按“停止”按钮后,装置均停止运行。
4.装置的安装
4.1安装前的准备工作
4.1.1设备开箱及验收。
根据装箱清单开箱对货物进行清点,检查货物有无缺损,并作好交接记录。
4.1.2熟悉安装图纸及安装使用说明书。
核对母线(主要是三通连接管的连接法兰)
的安装尺寸是否与干燥装置的图纸要求一致。
4.1.3搭好脚手架,准备好起吊设备。
4.1.4母线改造加装干燥装置的,应将母线外壳上原有的漏气开口封闭。
4.2安装步骤
4.2.1将干燥装置本体吊装就位,将底部框架与预埋件焊牢或用膨胀螺栓固定,还应将底部框架可靠接地。
4.2.2安装母线三通连接管,配有截流孔板的,应将相应规格(不同位置对应不同的规格)的截流孔板装上。
如是母线改造加装干燥装置的,则需按图纸要求在母线外壳上开孔,并焊接连接法兰。
安装后应将母线内的铝屑用吸尘器(用户自备)清除干净。
4.2.3按照图纸要求,结合现场实际情况,配接干燥装置的进、出气管道。
然后将出气口压力表等装上。
4.2.4安装湿度探头,按图纸要求接好线。
探头线应用金属软管保护。
4.2.5接好电源。
用户负责将电源线接至干燥装置的控制箱,并负责接送电。
4.2.6补刷油漆。
现场的油漆补刷工作由用户进行。
5.调试与运行
5.1打开干燥装置本体内的回气阀V1(罗茨风机正上方)、进气阀V2(干燥装置的右上方)、补气阀V3(干燥装置的背面,外接空气过滤器),V1、V2、V3为三只手动球阀。
装置正常运行后应调节三只阀门的开度,V1全开,V3二分之一开,并调节V2的开度,使压力表显示为1.6kPa左右。
运行几小时后观察母线上的橡胶伸缩套有无向内收缩现象,如有,说明母线内存在负压,这时可加大补气阀V3的开度。
调整完后将阀门定位,下次启动无需重复调节。
5.2调整电源相序。
将控制箱面板上的“自动/手动”转换开关打到“手动”→合上电源空气开关(上电)→用螺丝刀点按一下风机接触器“5KM”,观察罗茨风机电机的转向是否与转向标示一致→如转向反了,则将电源进线(不能只调罗茨风机电机的电源线,因为电动阀的转向与风机须保持一致)的任意两根相线互调即可。

秒钟,这时项目“开始”指示灯亮,将监控器的“开始”设定为50%;
I”“报警II”的设定,直至项目指示灯全熄。
将“停止”设定为20%,“报警I”、“报警II”不用设定。
这样设定表示在“自动”方式时,母线内湿度超过50%时,干燥装置将启动除湿,在低于20%时,装置在运行一个周期后将停止运行。
(出厂时已按上述数据设定好,用户一般无须重新设定)。
5.4温度数显调节仪的设定(出厂时已设定好,正常情况下用户不要调整)。
再生筒温
为AL1H),设定值为0℃;第二路报警为下限报警(提示符为AL2L),设定值为120℃。
用户如需调整,再生筒温度数显仪第一路报警上限设定值不得超过250℃,排气温度数显仪第二路报警下限设定值不得超过150℃。
5.5试运行(试运行前,必须保证V1、V2及V3打开)
上述步骤完成后,即可进行装置的试运行。
操作步骤和装置的正常动作过程如下表:
注意:合电源空气开关后,“PLC”及湿度监控器、温度数显调节仪等有5秒左右的自检时间,此时不要进行下一步操作。
5.6运行
装置试运行没有异常,干燥装置即可投入正式运行。
操作步骤按5.5条。
6.维护和检查
6.1罗茨风机应按照《罗茨风机使用说明书》上所要求的检查项目进行日常维护与检查。
观察罗茨风机齿轮箱的油位是否在要求的范围内,油位过低则应及时加注润滑油。
如罗茨风机有异常噪音、电机温度异常升高,则应及时停机检查。
6.2补气阀V3前设空气滤清器,应每周清理空气滤清器一次,确保补气清洁、顺畅。
厂家提供2个空气滤清器备品,如有损坏,请用户自行购买。
6.3封母干燥装置在使用4 年以后,根据实际使用效果,可考虑更换分子筛。
打开干燥筒体底部的分子筛放料口法兰,放完老化的分子筛后,紧上放料口法兰,并打开干燥筒上部的加料口法兰,注入新分子筛至离加料口法兰面下130mm处,用小棍搅拌均匀。
紧上加料口法兰。
注:更换所需分子筛材料由用户自行购买并更换。
