Abstract

The invention discloses a heat filler type deaerator with a stable deaerating function and an atomizing function. The heat filler type deaerator is characterized in that a heat-side inlet of an exhaust heat exchanger is communicated with a blowoff valve through a pipeline, a cold-side inlet of the exhaust heat exchanger is communicated with a deaerator water supply pipe, a cold-side water outlet of the exhaust heat exchanger is communicated with a deaerator water supply inlet through a pipeline, a heat-side inlet of a water outlet heat exchanger is communicated with a deaerator water outlet, a boiler water supply pump is connected to a heat-side outlet pipeline, a cold-side water inlet of the water outlet heat exchanger is communicated with the deaerator water supply pipe, a water supply pump is arranged on the deaerator water supply pipe, a differential pressure transmitter is arranged in a deaerator water tank, detected water level signals in the deaerator water tank are transmitted to a controller through the differential pressure transmitter, the controller transmits signals to a frequency converter, the frequency converter controls rotation speed of the water pump to adjust water supply, a pressure control gauge transmits pressure signals to the controller which controls opening of preheating pipeline electromagnetic valves, a temperature sensor transmits temperature signals to the controller, and then the controller controls opening of reheating steam electromagnetic valves.

Description

technical field [0001] The invention relates to an industrial boiler feed water deaerator, in particular to a thermal spray packing type deaerator capable of stably deoxidizing. Background technique [0002] A certain amount of oxygen and CO are dissolved in various water sources such as tap water and well water. 2 Once they enter the boiler with the boiler feed water, under the conditions of high temperature, pressure and electrolyte, the dissolved oxygen and carbon dioxide in the water will cause chemical and electrochemical corrosion to the metal wall of the boiler, so degassing (especially degassing) must be taken oxygen) measures. [0003] At present, my country's industrial boilers use softened water and desalinated water as boiler feed water, and the problem of dissolved oxygen corrosion is relatively prominent. Since the corrosion of boilers is a slow process, the harm it produces is not easy to detect in a short period of time. Therefore, some enterprises do not p...
