Description
Technical field
The utility model belongs to smoke abatement device technical field, is primarily related to a kind of smoke abatement and dust control of white cigarette gas and sets
It is standby.
Background technology
White cigarette is a kind of cigarette that industrial chimney often emits, and the reason for causing chimney to emit white cigarette is mainly：Flue gas is wet in desulfurizing tower
After method desulfurization, the high fever in flue gas also forms vapor by moisture absorption, after chimney discharge, when its diffusion velocity is less than waste gas
During the condensation rate of middle water vapour, white cigarette will be formed.Therefore when air temperature is high or dry, water recovery lacks in flue gas
Or evaporation is quickly, white cigarette is just few；Conversely, air temperature is low or during high humidity, the white vapour condensed out is more or evaporation is slow, just seems white
Cigarette is dense.
Existing desulfurizing tower after desulfurization and dedusting is carried out to flue gas, although can remove most dust in flue gas and
Sulfur dioxide, but be difficult thoroughly to remove to the micro ultrafine dust in flue gas, these ultrafine dusts can be together discharged into company with white cigarette
Air, substantial amounts of precious resources-water is not only consumed, and by smog（Water vapour）The dust of entrainment is difficult sedimentation.And with powder
Dirt crystal grain is core, and haze is formed together with smog, it is not easy to dissipates, is particularly more difficult to dissipate in the winter time.The reason for hardly possible dissipates
It is：The smog lta that steam is formed, and remaining dust is very tiny after desulfurization, although it is heavier than air, in smog
Entrainment under, sedimentation is difficult to, so wanting to allow dust settling it is necessary to remove the water vapour in smog.
The content of the invention
Thus the purpose of this utility model produces, a kind of smoke abatement device of white cigarette gas, the equipment is by reducing white cigarette
The discharge temperature of mist, the dust with the floating of white cigarette mist is settled, reach removing smog, reduce dust, eliminate white cigarette, avoid
The purpose of air pollution.With it is reasonable in design, easy to use, save water resource the characteristics of.
Inventor is by the research to white cigarette and dust floatation principle, it is believed that：The dust swum in gas, temperature are higher
It is more difficult to settle, the more low then more free settling of temperature；The amount of moisture vapor is more in flue gas, is more difficult to dedusting, easier formation white cigarette, water
The content of steam is fewer, easier depositing dust, is less susceptible to form white cigarette.
Principle accordingly, the utility model adopt the technical scheme that：A kind of smoke abatement device of white cigarette gas includes eliminating smoke
Tower, air blower, heat-exchange device, tube type dust removing device, described smoke elimination tower are sandwich structure, and desulfurization is provided with interlayer, is taken off
Smoke of gunpowder gas inlet port, air blower connector and top flue gas discharge opening, the tube type dust removing device are arranged in smoke elimination tower；It is described
The heat-exchange tube of heat-exchange device is located in smoke elimination tower to be intertwined and connected with tube type dust removing device, the entrance point warp knuckle of the heat-exchange tube
Stream valve is connected with radiator, the connection of the low-pressure end of the port of export and heat pump, and the high-pressure side of heat pump is connected with radiator；In the smoke elimination
The bottom of tower is provided with bottom flue gas discharge opening.
Further, the bottom of the smoke elimination tower is conical by its shape, and bottom is provided with dust outlet, and in dust outlet
Position is connected with auger.
Further, the tube type dust removing device is single tube deduster, i.e., single pipe is provided with smoke elimination tower.
Further, the tube type dust removing device is multi-tube dust cleaner, i.e., multiple tubulations are provided with smoke elimination tower.
The flue gas that the utility model comes out by using the method that three-level cools to shaft furnace cools down, and makes cigarette
Gas is down to 35 DEG C or so by 180 DEG C or so, has thus more lacked the content of water vapour in white cigarette gas, has eliminated white cigarette, has made in flue gas
Micro ultrafine dust settled, avoid the pollution to air, while save water resource.Flue gas warp after cooling dedusting
Cross after desulphurization and denitration and do not discharged directly, but enter smoke elimination tower top and cooling down first is carried out to flue gas, obtain flue gas
Further to utilize, energy consumption has been saved, has reduced cost.
The air blasted by air blower makes flue gas obtain cooling down again, although the flue gas after air cooling-down cools down
There is larger reduction with the temperature difference of air, but still do not reach the requirement of cooling down（Flue gas need cooling down to 10 DEG C-
50℃）, therefore, further cooled with the method for forced cooling cooling.The utility model will freeze by using heat pump to be situated between
Matter is sent into smoke elimination tower and carries out forced cooling cooling to the flue gas after air cooling-down cools down, and the refrigerant after being heated, leads to
Over pressurizeed radiates, and is sent into again by heat pump in smoke elimination tower and carries out forced cooling cooling to flue gas, this process is entered again and again
OK, so that flue gas has obtained forcing cooling.Flue gas after cooling, desulfurization and dedusting just become easier, and flue gas turns cold, and hold
Easy dedusting, and brought into without excessive heat in water, so water temperature will not raise substantially, the formation of vapor is reduced, is saved
About water resource, eliminates white cigarette.Meanwhile a large amount of dust, these powder are removed with dry method by the very high pipe precipitator of efficiency
Dirt can be removed directly, without secondary pollution, be had laid a good foundation for the desulfurization and dedusting of next step.Flue gas after dedusting is sent
Enter desulfurizing tower and carry out desulphurization denitration and dedusting, the dust in flue gas has almost been taken off, sulphur and nitre have also remained little, and flue gas is
Through becoming very clean, reach discharge standard, avoid environmental pollution.
