Description
Technical field
The present invention relates to a kind of white devices of boiler smoke qi exhaustion, belong to boiler smoke processing technology field.
Background technology
Due to containing a large amount of vapor in boiler smoke, ambient, cool air is encountered when the heat smoke of boiler is discharged in air
When, it may occur that heat exchange；When flue-gas temperature is reduced to saturation temperature, the vapor in flue gas begins to condense into small water
Pearl, with further decreasing for flue-gas temperature, more vapor can condense into a large amount of tiny drops of water, visually seem and be exactly
Emit white cigarette.There are two ways to eliminating white cigarette at present, first, flue gas is directly heated, second is that first condensation flue gas reheats flue gas.
Snead process is exactly so that flue-gas temperature is far above saturation temperature, high temperature cigarette using additional heat source heating flue gas
Gas is cooling in discharge process, and when being cooled to saturation temperature, the range of scatter of flue gas is very big, due to aqueous in flue gas
Amount is certain, so a certain amount of vapor condenses into small droplet interior on a large scale, visually just can't see, reaches and disappear
The purpose of white-smoke-removing；
It is exactly first to condense the vapor in part of smoke, it is therefore an objective to reduce flue gas using additional low-temperature receiver that first condensation, which reheats,
Saturation temperature, then slightly heat flue gas, make flue gas far from saturation state, smoke exhaust process just can't see white cigarette.
The method that both the above eliminates white cigarette is required for the additional energy, not only consumes energy but also equipment investment is big, equipment body
Product is also big.
Invention content
It is an object of the invention to overcome the shortcomings of the prior art, and provide it is a kind of simple in structure, it is easy to use, can
It leans on, by using ambient, cool air, is configured by reasonable air, reduce energy consumption, the small white device of boiler smoke qi exhaustion of equipment investment.
The purpose of the present invention is come what is completed, a kind of white device of boiler smoke qi exhaustion, it includes one by following technical solution
Heat exchanger and the gas mixer composition being connected with heat exchanger, one end of the heat exchanger is respectively arranged with ambient, cool air
