Description
Technical field
The present invention relates to technical field of waste gas treatment, a kind of processing method for boiler smoke.
Background technology
Boiler is the heat energy utilizing fuel or other energy, water or medium are heated, output heat energy produces for people and the plant equipment of living needs, in its production process of existing boiler its fuel combustion produce containing flue dust, the flue gas of sulfur dioxide and carbon dioxide etc. is all to be directly discharged in air by chimney, its exhaust gas temperature is typically not less than 180 DEG C, reach as high as 250 DEG C, the discharge of this high-temperature flue gas not only causes a large amount of thermal waste, also result in the atmosphere pollution as representative with flue dust and sulfur dioxide simultaneously, result shows after deliberation, the concentration of Sulfur Dioxide In The Atmosphere often increases by 1 times, general mortality rate increases 1l%；TSP concentration often increases by 1 times, and general mortality rate increases by 4%；And the excessive emissions of carbon dioxide can cause global warming phenomenon；Therefore processing means and the processing method of a kind of convenient and practical boiler smoke it are badly in need of.
Summary of the invention
The technical problem to be solved is to provide a kind of boiler smoke processing method, and this method can solve the in line problem causing air pollution in the air of existing boiler smoke.
In order to solve the problems referred to above, the technical solution adopted in the present invention is: this boiler smoke processing method, use a kind of boiler smoke treating column, this treating column includes the tower body offering gas approach, exhanst gas outlet and liquid outlet, be provided with in described tower body make flue gas turn back in described tower body flowing multiple endothermic tube groups, level arrange full glass microporous filter membrane, activated carbon filter membrane and be positioned at below described activated carbon filter membrane the nozzle towards tower body being arranged on described tower body sidewall and connecting with liquid-transport pipe-line；Described endothermic tube group passes through its water inletWithCarbonated drink outlet has the circulating line of pump and steam-water separator to be connected with the connection being arranged at outside described tower body；Cold medium in described endothermic tube group is water, and described endothermic tube group is regularly arranged and the multiple U-tube communicated of connecting；
Its processing procedure is as follows:
A, boiler smoke pipeline is connected with the gas approach for the treatment of column；
B, filter the suspended particulate in flue gas by described full glass microporous filter membrane；By the sulfur dioxide in described activated-carbon filter membrane filtration smoke abatement gas；
C, by described endothermic tube group, the flue gas that temperature is 180 degrees Celsius to 250 degrees Celsius is down to 50 degrees Celsius to 70 degrees Celsius；
D, by described liquid-transport pipe-line and described nozzle, by concentration be 26%, flow velocity be that the ammonia spirit of 3 meter per seconds sprays to flue gas, ammonia spirit is 1: 8 with the volumetric ratio of flue gas；
E, by d process generate ammonium hydrogen carbonate be collected by described liquid outlet；
F, until boiler stops burning fuel, to obtain final product.
In technique scheme, more specifically technical scheme is it may also is that offer water inlet, carbonated drink import, delivery port and venthole on described steam-water separator, described carbonated drink import exports with the carbonated drink of described endothermic tube group and is connected, and described delivery port is connected with the water inlet of described pump.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, owing to being provided with full glass microporous filter membrane and activated carbon filter membrane in tower body, and it is provided with the nozzle connecting liquid-transport pipe-line below activated carbon filter membrane, during work, suspended particulate and sulfur dioxide in flue dust are first effectively filtered out, then the ammoniacal liquor in liquid-transport pipe-line sprays to flue dust by the collecting carbonic anhydride in flue dust, the gas obtaining cleaning enters in the air, free from environmental pollution, it is ensured that people's is healthy；And its generate ammonium hydrogen carbonate can carry out again with, saved resource.
2, due to that be provided with water in tower body and make flue gas turn back in tower body the endothermic tube group of flowing, it extends the flowing time of flue gas,Make the heat in high-temperature flue gas fully by U Water in type pipeline effectively absorbs, and water is changed into steam and the mixture of water and flows out recycling。
3, owing to being provided with steam-water separator, steam and water are exported by steam-water separator respectively, and steam is used effectively, and water is again introduced into endothermic tube group and carries out heat absorption circulation, has saved water resource.
