Abstract

An exhaust recovery device of a deaerator comprises a packing tower shell body, wherein the packing in the packing tower shell body is divided into an upper packing layer and a lower packing layer; the top part of the packing tower shell body is provided with an exhaust port; the upper part of the packing tower shell body is provided with a cold water inlet; the lower part of the packing tower shell body is provided with a steam inlet and a hot water outlet; a circulating hot water inlet is arranged on the packing tower shell body between the upper packing layer and the lower packing layer; one end of a water outlet pipeline is communicated with the hot water outlet and the other end of the water outlet pipeline is respectively communicated with the inlets of two water pumps; the outlets of two water pumps are communicated with the circulating hot water inlet; the pipeline between two water pumps is communicated with the water inlet pipe of the deaerator; the upper packing layer and the lower packing layer are structured packing layers; and the water pumps are centrifugal pumps. The exhaust recovery device of the deaerator can recover and utilize the heat in the steam which is exhausted by the deaerator, reduces the atmospheric emissions, saves the energy, protects the environment, and has simple structure and convenient use.

Description

technical field [0001] The invention relates to a boiler heat recovery device, in particular to a deaerator exhaust gas recovery device. Background technique [0002] In the production process of industrial enterprises with boilers and electric power enterprises, the deaeration method of boiler feed water usually adopts thermal deaeration method to ensure the quality of feed water. This deaeration method has the advantages of simplicity, reliability and good deaeration effect. However, the steam generated by the deaerator is generally discharged directly into the atmosphere, which not only increases the amount of atmospheric emissions and causes thermal pollution to the environment, but also The heat is not used, wasting energy. According to calculations, an atmospheric deaerator with an output of 100 tons, under normal operating conditions, when the water temperature in the deaerator reaches 104°C and the pressure in the deaerator reaches above 0.02MPa, the amount of steam...
