Description
Technical field
The utility model belongs to technical field of metallurgical equipment, is related to a kind of water curtain dust-removing waste gas exhaust system.
Background technology
Our company is a national emphasis steel private enterprise, is ratified through Hubei Province through letter, by group integrate under Hubei Province it is domestic
6 iron and steel enterprises, eliminate the backward production facilities, organizational technology transformation.
Since establishment, energy-saving and environmental protection, intelligent control, the exploitation for the technologies such as recycling and equipment have been had been devoted to it and have changed
It makes.
Exhaust-gas treatment be the necessary links that Expenses Cost is higher in metallurgical process, intractability is larger and enterprise whether
Meet the important technology of modern production standard, at present, for last one of processing links of exhaust gas, generally using direct emission
Mode, exhaust gas is repeatedly reacted, harmful substance therein is made to be neutralized into stable material, still, by repeatedly handling it
In exhaust gas afterwards, more harmless particle is adulterated, also doped portion harmful substance, directly arrange the exhaust gas for carrying a large amount of particles
It puts, is affected to air quality.
Invention content
The purpose of this utility model is for the above problem existing for existing technology, provides a kind of water curtain dust-removing waste gas row
Place system, technical problem to be solved in the utility model be how the dust and harmful substance in high efficiency filter exhaust gas.
The purpose of this utility model can be realized by following technical proposal：A kind of water curtain dust-removing waste gas exhaust system,
It being characterized in that, this exhaust system includes main exhaust, elbow and water sealed tank, and the upper end of the main exhaust connects the elbow,
The elbow is placed in the water sealed tank, is had several downward opening branch exhaust pipes on the elbow, is contained in the water sealed tank
There is the solvent that water level is higher than on the opening of branch exhaust pipe, several nozzles, the water seal are provided on the inner wall of the water sealed tank
The upper end of tank is sealed by a cover board, has venthole on the cover board.
Exhaust gas flows into branch exhaust pipe from main exhaust, is discharged after the filtering of solvent by venthole, in the process, spray
Mouth sprays solvent, and the exhaust gas to that will discharge is eliminated in the gas that branch exhaust pipe is discharged, into traveling water screen dedusting due to originals such as bubbles
Because that can be solvent in water sealed tank or in addition without the water source of the dust and harmful substance that are filtered, nozzle
Water tank.
In a kind of above-mentioned water curtain dust-removing waste gas exhaust system, the lower end of the main exhaust connects an air blower.
In order to improve exhaust efficiency, be also prevented from water sealed tank fluid-tight structure caused by exhaust resistance and influence to be vented, in master
The lower end of exhaust pipe sets an air blower, so as to increase off-gas flows pressure.
In a kind of above-mentioned water curtain dust-removing waste gas exhaust system, the bottom of the water sealed tank offers a return port.
Return port is used to clear up water sealed tank, is also used for replacing the solvent in water sealed tank, wherein, solvent can be water
Or the neutralizer modulated for exhaust gas constituents.

Fig. 1 is the overall structure diagram of this exhaust emission system.
In figure, 1, main exhaust；2nd, elbow；3rd, water sealed tank；4th, branch exhaust pipe；5th, nozzle；6th, cover board；7th, venthole；8、
Return port.
Specific embodiment
It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in Figure 1, this exhaust system includes main exhaust 1, elbow 2 and water sealed tank 3, the upper end of main exhaust 1 connects
Elbow 2, elbow 2 are placed in water sealed tank 3, have several downward opening branch exhaust pipes 4 on elbow 2, water level is filled in water sealed tank 3
Higher than the solvent on the opening of branch exhaust pipe 4, several nozzles 5 are provided on the inner wall of water sealed tank 3, the upper end of water sealed tank 3 leads to
It crosses a cover board 6 to seal, there is venthole 7 on cover board 6.
Exhaust gas flows into branch exhaust pipe 4 from main exhaust 1, is discharged after the filtering of solvent by venthole 7, in this process
In, nozzle 5 sprays solvent, in the gas discharged to the exhaust gas that will be discharged into traveling water screen dedusting, elimination branch exhaust pipe 4, due to
For the reasons such as bubble without the dust and harmful substance that are filtered, the water source of nozzle 5 can be the solvent in water sealed tank 3,
It can be other water tank.
The lower end of main exhaust 1 connects an air blower (not drawing)；In order to improve exhaust efficiency, it is also prevented from 3 liquid of water sealed tank
Seal structure caused by exhaust resistance and influence to be vented, the lower end of main exhaust 1 set an air blower, so as to increase exhaust gas gas
Flowing pressure.
The bottom of water sealed tank 3 offers a return port 8；Return port 8 is also used for for clearing up water sealed tank 3 in water sealed tank 3
Solvent replaced, wherein, solvent can be water or the neutralizer modulated for exhaust gas constituents.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
