Problems solved by technology

[0005] (2) Colored smoke plume
This treatment method not only makes the slag contain a large amount of waste heat and cannot be fully utilized, which affects the thermal efficiency of the boiler, but also causes waste of water resources to a certain extent due to the evaporation of circulating water, and also causes thermal pollution to the environment.
During the immersion of circulating water into slag, the steam generated will also cause corrosion damage to the structure of the boiler body and boiler room in the long run

Embodiment Construction

[0042] The present invention will be further described below in conjunction with accompanying drawing.

[0043] According to the first aspect of the present invention, such as figure 1 As shown, the present invention provides an auxiliary heating and whitening device for boiler chimney exhaust, which includes a boiler slag hopper 10 , an air-cooled slag cooler 20 , a cyclone separator 30 , an air preheater 50 and a dust collector 60 .

[0044] Specifically, as figure 2 As shown, the air-cooled slag cooler 20 is respectively provided with a slag input port 21 , a gas input port 24 , a gas output port 25 , a slag inlet port 22 and a slag outlet port 23 .

[0045] Wherein, the boiler slag hopper outlet 11 at the lower end of the boiler slag hopper 10 is connected to the slag input port 21 of the air-cooled slag cooler 20 . The slag produced by boiler combustion enters the air-cooled slag cooler 20 through the slag input port 21 , and the air at normal temperature enters the ai...

Abstract

The invention relates to a boiler chimney smoke discharge auxiliary heating white smoke elimination device and method and relates to the technical field of energy conservation and environmental protection. Through the boiler chimney smoke discharge auxiliary heating white smoke elimination device and method, the technical problems that a great deal of waste heat cannot be made full use of and theheat efficiency of a boiler is affected in the prior art are solved. The boiler chimney smoke discharge auxiliary heating white smoke elimination device comprises an air-cooled slag cooler. In the air-cooled slag cooler, heat carried by furnace slag is used for heating the air; and through recycling of waste heat of the furnace slag of the boiler, the purpose of reducing energy loss is achieved.

Description

technical field [0001] The invention relates to the technical field of boiler energy saving and environmental protection, in particular to a device and method for assisting temperature rise and whitening of boiler chimney exhaust smoke. Background technique [0002] At this stage, in order to achieve environmental protection emissions, the boiler units of coal-fired power plants in my country mostly use the wet desulfurization process to desulfurize the flue gas. This process has high desulfurization efficiency and good operation stability, and is one of the main technologies for atmospheric environment management in my country. However, there is also a prominent problem. The flue gas treated by this process is discharged into the atmosphere through the chimney. Due to the background color of the sky, sky lighting, viewing angle, etc., it is usually white, gray, blue, etc. visually, causing serious secondary pollution. Pollution and visual pollution, and in severe cases, the...
