一、设备简介

1. Equipment Introduction

本设备用于锅炉给水的除氧。

This equipment is used to deoxygenate the boiler feedwater.

1、本设备为热力喷雾淋水盘式除氧装置，由高压除氧器与除氧水箱组成，用于电站锅炉给水的除氧。在正常工作下，利用汽轮机抽汽或压力得到控制且具有安全泻放装置的汽源作为加热蒸汽，将进入除氧器的水加热到与除氧器运行压力相对应的饱和蒸汽温度，根据道尔顿定律，将溶于水的氧与二氧化碳等非凝结气体除去，达到标准规定的除氧水，储存在除氧水箱中，随时准备供给用水的需要。

1). This deaerating equipmentis of spray and packing type, consisting of high pressure deaerator and storage tank. It is applied to feedwater deoxygenation of power station boiler, hot water boiler and other hot water equipment. In normal working condition, turbine's extraction steam or other steam source which pressure is under control and has safety relief device will be used as heating steam to heat the water entering the deaerator to the saturation steam temperature corresponding to the operation pressure of the deaerator. According to the Dalton Law, it will eliminate uncondensable gases dissolved in the water, such as oxygen and carbon dioxide, etc., so that the deoxygenated water will satisfy the standard requirements. The deoxygenated water will be stored in the storage tank for supply at any time.

2、本设备适用于在设定、滑压力下作定压运行。定压运行时，备用加热蒸汽通过电动调节阀进入除氧器。根据除氧器内部的设定压力为0.147MPa.a，自动调节阀开度，以控制入口加热蒸汽量。

2). This equipment is applicable to constant pressure and sliding pressure operation under the set pressure. Constant pressure operation under the set pressure ,The heating steam of Assistance enters the deaerator through the motor operated adjust valve. According to the internal set pressure (0.147Mpa.a) of the deaerator, it will automatically adjust the valve opening to control the flow of the inlet heating steam.

3、高压除氧器采用双封头卧式结构，通过支座坐落在水箱筒体上，水箱采用双封头卧式结构，除氧器及水箱通过下水管和蒸汽连通管进行连通，维持除氧器和水箱压力平衡，保证设备安全稳定运行。

3). The high pressure deaerator adopts double-head horizontal construction , Pass to pay to install in the storage tank tube body top, The storage tank adopts double-head horizontal structure.connecting with storage tank cylinder by the downcomer and steam connecting pipe, Maintain the pressure balance about the deaerator and the storage tank, Promise an equipments

a safety and stabilize to circulate.

4、高压除氧器设有（A48Y-16C）型弹簧全启式安全阀作为泻放装置，安全阀的开启压力和数量见设备图纸。

4). The high pressure deaerating equipment is equipped with (A48Y-16C) spring full opening safety valve as pressure relief device. For the opening pressure of safety valve and number , please refer to the equipment drawing.

5、在水箱筒体上设有2对就地磁翻板水位计，用于现场观察，还根据需要设有3对平衡容器，用于远方水位显示及报警、控制水位，当水位高于预定值时，及时发出高水位溢流放水信号，自动开启气动调节阀进行排水，以维持水箱中的正常水位，保证设备稳定运行。另设2对备用水位测量接口，便于用户根据需要设置水位控制仪表。

5). There is two group local magnetic conversion water level gauge equipped on the storage tank cylinder for local observation. According to requirement, it is also equipped with three group of balance vesse for remote water level indication and alarm. When water level is higher than the predefined value, it will give emergency drain signal and automatically open the air control regulates valve. It is equipped with two group of balance vessel to provide water level automatic
