Description

Self excitation deflection scrubber

The utility model belongs to liquid isolates the device of the fixedly particle of disperse as release agent from gas, be specially adapted to the dedusting of Industrial Boiler and stove.

In the past, whirlwind dry dust removal, the dedusting of wet type fiber crops stone, fountain dedusting, electric precipitation etc. are arranged, these dedusters are not that efficient is low, and energy consumption is big, cost an arm and a leg exactly, and complex structure, perhaps management has carelessness slightly, and efficient will descend.A kind of baffling deduster is arranged, it comprises tank, smoke inlet pipe, deflector, deflection plate, escape pipe and level controling mechanism, its air inlet pipe exports perpendicular to horizontal plane and is positioned at below the water surface, this deduster exists that resistance is big, power consumption is high, structure is complicated, when the blower fan stall, flue gas is promptly shut, can't natural air inducing etc. problem, bring inconvenience to commercial Application.

Task of the present utility model is to adopt a kind ofly impact, baffling, injection, centrifugal molten for the special construction of one to have been solved the problems referred to above.Its efficiency of dust collection height, less energy consumption, cost is low, and volume is little, and is in light weight, easy to maintenance, non-secondary pollution, the ratio of performance to price is higher, and is easy to utilize.

The utility model comprises tank, air inlet pipe, deflector, deflection plate, escape pipe and liquid controlling organization, it is characterized in that the gas outlet of air inlet pipe is 0-500mm to water surface distance, and air inlet pipe exports main airflow direction and horizontal plane angle is 10-80 °.The oblique impact liquid level of flue gas, by water washing, current and droplet that the liquid level that is impacted evokes, be arranged on the upwards revolution of deflector water conservancy diversion of airflow direction front upper place, by being located at the first road deflection plate baffling of deflector top, cause centrifugal rotation again, make fixedly separate particles once more, current are beaten on deflection plate past dirty, and one of feedback formation, two roads or several roads water curtain are strengthened gas purification.Deflector can be dull and stereotyped, also can be curved slab, can utilize original tank, also can be provided with in addition.The deflection plate that causes centrifugal rotation is dull and stereotyped, also can be curved slab.The first road deflection plate is as being dull and stereotyped, and preferably to be 10 ° of-85 ℃ of angles better with vertical.For further purification,, also can establish multiple tracks stream plate again in above-mentioned self-excitation baffling structure back.Through repeatedly baffling is centrifugal, can make the further isolation of purified of gas-liquid solid phase.Several roads, back deflection plate can be located at certain position in the air-flow way, as long as cause the baffling centrifugal action.The deflection plate that second road is later can be taked a kind of special baffling structure, and promptly its horizontal cross-section is " Z " shape or serpentine, causes and concentrates repeatedly baffling to purify.The scrubber that has, flue gas escape pipe inlet is closer apart with the water surface, takes away in order to prevent to produce from goading water smoke into action, can establish water-stop sheet in the air-flow way water is isolated.

Above-mentioned self-excitation baffling structure is good to take following three kinds of structures: (1) air inlet pipe exports perpendicular to the water surface, and there is a taper current divider its below, makes the gas shunting and the oblique water surface of injecting.The distance that air inlet pipe exports to the water surface is 10-400mm.For making compact conformation, deflector is annular cylinder or curved surface (local disconnection or layer structure are suitable therewith) substantially, and the first road deflection plate is circular cone or curved surface (local disconnection or layer structure are suitable therewith) substantially.(2), air inlet pipe exports perpendicular to horizontal plane, outlet band horn mouth, there is a taper current divider its below, is beneficial to oblique injecting.Export to water surface distance and be preferably 0-100mm.The shaped position of deflector and deflection plate is with (1).(3), air inlet pipe outlet is the flat degree of lip-rounding, air inlet pipe and horizontal plane angle are 10 °-80 °.It is 0-50mm that pipe exports to water surface distance.

In order further to improve clean-up effect,, dispose fluid jetting head near being preferably in the air inlet mouth of pipe for the scrubber of above-mentioned various self-excitation baffling structural formulas.For example, for (1) (2) kind self-excitation baffling structure, be preferably in taper current divider top and establish shower nozzle, shunting cap preferably is with on shower nozzle top, is preferably the shower nozzle that can go out the continuous water surface, to form envelope formula water curtain.For stiffening effect, can spray into the various S of taking off agent.This shower nozzle can recycle water in the tank.Also available other fluid level control devices recycle water.

Above-mentioned various version all can be made parallel and/or series-mode frame, to strengthen its clean-up effect.

Dust removing effects of the present utility model can reach more than 95%, and requirement meets international standards.Taking off S leads and can reach more than the 50-90%.Volume is little, in light weight, resistance is little, have that efficiency of dust collection height, cost are low, compact conformation, floor space are few, less energy consumption, easy to maintenance, water can be recycled, non-secondary pollution, the very high outstanding advantage of the ratio of performance to price, applicable to the purification of multiple gases, be particularly suitable on 0.5-20 ton Industrial Boiler and stove, applying.
