Technical field

The utility model belongs to boiler, the kiln gas cleaning equipment of field of environment protection, is specifically related to the architecture advances of wet dust removal desulphurization device.

Background technology

Wet dust collection technology both can dedusting, can remove the pernicious gas in the flue gas again, was widely used in the dust-removal and desulfurizing of coal-fired flue-gas.China abounds with numb stone, utilizes the anticorrosive wear-resistant of numb stone to decrease performance production gallet water curtain dust collector, is applied to the dedusting of flue gas.Existing granite with water film class deduster is generally monotubular tower shape, and its operation principle is to utilize centrifugal force that flue dust is thrown on the wall, and the flue dust that is thrown to wall is washed by the moisture film of deduster inwall, thereby reaches the purpose of dedusting.This device once played a role to the udst separation of coal-burning boiler, kiln gas.But it is short that its shortcoming is the fume-dehydrating stroke, water content height in the flue gas after being purified, and easy-to-rust system either machine, pipeline etc., the maintenance rate height, operating cost increases.

Summary of the invention

Technical problem to be solved in the utility model is exactly the deficiency that overcomes traditional numb stone class hydrofilter, provide a kind of and not only can improve efficiency of dust collection and desulfuration efficiency, and fume-dehydrating is effective, effectively safeguards system safe operation, reduce maintenance, prolong system either machine, pipeline life, reduce cost the Sleeve-type wet dust removal and desulfurization device of being convenient to promote.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of Sleeve-type wet dust removal and desulfurization device, it comprises inner core, nozzle, air inlet, exhaust outlet, overflow ducts, overflow launder, it is characterized in that inner core is with urceolus, in, constitute process chamber just between the urceolus, described nozzle is arranged on the top of process chamber just, air inlet is arranged on process chamber top just, exhaust outlet is arranged on the top of inner core, in overflow ducts is arranged on, the bottom of urceolus, overflow launder is arranged on the outside of urceolus, be communicated with overflow ducts and gutter, just be provided with the swash plate that can form liquid film in the middle part of the process chamber, swash plate becomes angle α with horizontal plane, have the self-excitation passage on the barrel of inner core bottom, and the inner core bottom is provided with the self-excitation chamber.

As further improvement of the utility model, described urceolus height is lower than inner core, the self-excitation passage becomes angle β with the diametric(al) of inner core, become angle γ again with horizontal plane, swash plate is one deck or two layers or more, and the self-excitation port number is more than two or two, and the α angle is 20～50 ℃, the β angle is 15～45 ℃, and the γ angle is 15～45 ℃.

The utlity model has following advantage:

Fume-dehydrating is effective, the safeguards system safe operation, reduces maintenance, prolongs system either machine, pipeline life, reduces operating cost, be convenient to promote, and resistance is low in the gas cleaning process, purification efficiency height, effective.

The specific embodiment

Shown in Fig. 1～4, the utility model comprises inner core 7, nozzle 6, air inlet 5, exhaust outlet 8, overflow ducts 12, overflow launder 10, it is characterized in that inner core 7 is with urceolus 4, in, urceolus 7, constitute process chamber 2 just between 4, described nozzle 6 is arranged on the top of process chamber 2 just, air inlet 5 is arranged on process chamber top just, exhaust outlet 8 is arranged at the top of inner core 7, in overflow ducts 12 is arranged on, urceolus 7,4 bottom, overflow launder are arranged on the outside of urceolus 4, are communicated with overflow ducts 12 and gutter 11, be provided with the swash plate 3 that can form liquid film at first process chamber 2 middle parts, swash plate becomes angle α with horizontal plane, have self-excitation passage 1 on the barrel of inner core 7 bottoms, and inner core 7 bottoms are provided with self-excitation chamber 9, described urceolus 4 highly is lower than inner core 7, self-excitation passage 1 becomes angle β with the diametric(al) of inner core 7, and becoming angle γ, swash plate again with horizontal plane is one deck or two layers or more, the self-excitation port number is more than two or two, the α angle is 20～50 ℃, and the β angle is 15～45 ℃, and the γ angle is 15～45 ℃.

Operation principle of the present utility model is as follows: contain the flue gas of dust and sulfur dioxide, enter process chamber 2 just by air inlet 5.The dust-removal and desulfurizing absorption liquid sprays into process chamber just by nozzle 6 with atomised form.The gas, liquid, solid three-phase contacts, and by effects such as inertial collision, wetting and interceptions, tentatively realizes dedusting and removes pernicious gas.Flue gas and liquid mist continue to move downward, and form liquid film on swash plate 3, and the contact area of enlargement gas and liquid further contacts gas liquid, improve clean-up effect.Two-layer up and down swash plate incline direction is opposite, makes along the upper strata swash plate and is directed downwards the surface that the gas, liquid and the solid particle front that rotatablely move strike lower floor's swash plate, strengthens the contact of gas liquid solid three-phase, further improves clean-up effect.Then, the flue gas of preliminary purification is by self-excitation passage 1, enters the self-excitation chamber 9 of inner core 7 bottoms with specific angle, makes gas and liquid further fully mix the intensified dust removal and desulphurization effect.Flue gas after being purified is carried out fume-dehydrating in the rotating centrifugal mode in inner core 7.Flue gas after the dehydration enters secondary tower or flue through the exhaust outlet 8 on inner core 7 tops, enters atmosphere through air-introduced machine, chimney again.Dust-removal and desulfurizing sewage enters gutter 11 through overflow ducts 12 and overflow launder 10, enters sedimentation basin.Sewage in the sedimentation basin can recycle through precipitation or after other modes handle.
