Especially in the chemical industry workshop of liquid crystal intermediates and medicine intermediate, having a large amount of dust is extend in exhaust system, because exhaust system does not arrange air cleaning unit usually, dust in workshop and volatile organic substance are all directly discharged in air, whole industrial production district is caused to fill the air pungent smell, cause great harm to environment, impact the health of other staff, even the residential block of periphery all can be had a strong impact on.
Existing air cleaning facility, normally adsorbs the gas organic molecule in exhaust system or decomposes, and is to discharge after gas obtains certain purification again.Like this gas of discharging in the exhaust system of workshop is processed, the pressure of environment can be alleviated, but, effectively can not can not be processed by the dust in air-flow, even can be caused serious damage to equipment.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of laser air cleaning system with dust preprocessing function.
The utility model adopts following technical scheme:
Have a laser air cleaning system for dust preprocessing function, it comprises the exhaust hood, dust pretreatment system, laser air purifier and the centrifugal fan that are linked in sequence by exhaust duct;
Described dust pretreatment system comprises gas flare, storage tank, water pump, coalescer, Venturi tube and cyclone dust collectors;
Wherein, described gas flare, coalescer, Venturi tube and cyclone dust collectors are linked in sequence by exhaust duct, and described gas flare import is connected with exhaust hood, and the air outlet of cyclone dust collectors is connected with the import of laser air purifier;
The water inlet of described water pump is connected with storage tank, delivery port is connected with Venturi tube and coalescer respectively by water supply line, be connected water supply line end with described coalescer and be provided with atomizer, the water supply line end be connected with Venturi tube is arranged at the trunnion place of Venturi tube.
Improve further as the utility model, described dust pretreatment system also comprises the heat-exchange device be connected with gas flare by heat exchanging pipe.
Improve further as the utility model, described dust pretreatment system also comprises blowdown storage tank, and the bottom discharge openings of described cyclone dust collectors is connected with blowdown storage tank.
Improve further as the utility model, also comprise the air dryer be arranged between cyclone dust collectors and laser air purifier.
Good effect of the present utility model is as follows:
The utility model adds dust pretreatment system before laser air purifier, effectively the dust in waste gas can be removed in advance, and then by laser air purifier, the organic gas molecule in waste gas is processed, eventually pass through the waste gas of process not containing any organic matter, directly be discharged in air by the outlet of centrifugal fan, can not impact environment, ensure that the quality of surrounding air and the living environment quality of resident.
Wherein, waste gas sprays through the flame of 1200 degree in gas flare, the dust material of the overwhelming majority and a part of organic gas can be removed, after air-flow enters coalescer, because water pump supplies water, by the water atomization that atomizer will spray into, tiny dust is fully contacted with water smoke, mutual parcel, form larger particle, then through Venturi tube, air-flow sharply accelerates at the flow velocity at trunnion place, the water that water pump is sprayed into is atomized under the effect of powerful air-flow, the dust formed in air-flow is wrapped up by water smoke further, form solid matter and the mud of larger particle, settle down in cyclone dust collectors.When the waste gas of the chalk dust removing of entering over enters the process of laser air purifier again, treatment effect is splendid, and saves a large amount of energy.
The heat of gas flare can be recycled by arranging of heat-exchange device, to workshop heating or to steam generating equipment heat supply, greatly can save the consumption of the energy, reduce operating cost.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
In the accompanying drawings: 1 exhaust hood, 2 exhaust ducts, 3 gas flares, 4 heat exchanging pipes, 5 heat-exchange devices, 6 water supply lines, 7 storage tanks, 8 water pumps, 9 coalescers, 10 centrifugal fans, 11 laser air purifiers, 12 Venturi tubes, 13 cyclone dust collectors, 14 blowdown storage tanks, 15 air dryers.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of laser air cleaning system with dust preprocessing function as shown in Figure 1, it comprises the exhaust hood 1, dust pretreatment system, laser air purifier 11 and the centrifugal fan 10 that are linked in sequence by exhaust duct 2.Wherein, centrifugal fan 10 is the blower unit of whole system, is the power source of air-flow, and by the effect of centrifugal fan 10, exhaust hood 1 could will produce ready-made air intake in exhaust system.Centrifugal fan 10 is placed on the end of whole system, can ensure that the power in the flow process of air-flow can not significantly be decayed, and can not cause corrosion to blower fan and damage.
Described dust pretreatment system comprises gas flare 3, storage tank 7, water pump 8, coalescer 9, Venturi tube 12 and cyclone dust collectors 13; Wherein, described gas flare 3, coalescer 9, Venturi tube 12 and cyclone dust collectors 13 are linked in sequence by exhaust duct 2, and the import of described gas flare 3 is connected with exhaust hood 1, and the air outlet of cyclone dust collectors 13 is connected with laser air purifier 11 import.In described gas flare 3 bocca interval carry out flame injection, its flame temperature is 1000-1200 DEG C, and can burn most dust instantaneously, high-temp combustion avoids the generation of the harmful substances such as bioxin.
As shown in Figure 1, the water inlet of described water pump 8 is connected with storage tank 7, delivery port is connected with Venturi tube 12 and coalescer 9 respectively by water supply line 6, be connected water supply line 6 end with described coalescer 9 and be provided with atomizer, water supply line 6 end be connected with Venturi tube 12 is arranged at the trunnion place of Venturi tube 12.Be injected in coalescer 9 after described atomizer makes water fogging, the dust that burning is produced unburned dust is wrapped to form the larger particulate matter of volume through water smoke, air-flow is through the trunnion place of Venturi tube 12, because caliber diminishes, gas flow rate increases instantaneously, by the atomization of water current passed into, dust and dust cohesion is made then to settle down in cyclone dust collectors 13 further, so far, dust in the gas of exhaust system is all removed, and the volatility of organic solvent is stronger, and major part can not be soluble in water, and under the effect of air-flow, still enter into laser air purifier 11 in the form of a vapor, then under the effect of laser air purifier 11, there is physical change and chemical change further, air-flow is effectively purified, centrifugal fan 10 is finally had to be discharged in air.Containing dust and easily organic in the gas of discharging, without any peculiar smell.
