Waste heat recovery and demisting system and method for exhaust steam and continuous sewage of garbage power station

Abstract

The invention provides a waste heat recovery and demisting system and method for exhaust steam and continuous sewage of a garbage power station. The production environment of the garbage power stationcan be beautified, and the loss of steam water and heat can be reduced. A water inlet pipeline is connected with an inlet of a first-stage heat exchanger, the first-stage heat exchanger is connectedwith a second-stage heat exchanger, the second-stage heat exchanger is connected with a third-stage heat exchanger, and the third-stage heat exchanger is connected with a deaerator; a drain flash tankand a drain tank are both connected with the first-stage heat exchanger; the drain tank is further connected with the first-stage heat exchanger and the third-stage heat exchanger; a continuous blowdown flash tank is connected with the second-stage heat exchanger, and a periodic blowdown flash tank is connected with the second-stage heat exchanger; the deaerator is connected with the third-stageheat exchanger; a first temperature measuring device is installed on the first-stage heat exchanger, a second temperature measuring device is installed on the second-stage heat exchanger, and a thirdtemperature measuring device is installed on the third-stage heat exchanger; and an exhaust steam demister is arranged on an exhaust steam pipeline of the periodic blowdown flash tank.

Description

technical field [0001] The invention relates to a waste heat recovery and defogging system and method for steam exhaust and continuous sewage discharge in a garbage power station. Background technique [0002] Waste incineration power generation has gradually become the main way of domestic waste disposal in my country. In the construction and operation of waste power generation, environmental protection has always been one of the most concerned issues in society. The exhaust steam in traditional waste-to-energy plants goes directly to the atmosphere, often forming the phenomenon of "white smoke". This phenomenon not only easily misinterprets the environmental protection issues of waste-to-energy plants, but also increases the water and heat in the power station's thermal system. loss. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a waste heat recovery and defogging sys...
