At present, domestic fume purifying treatment technology adopts the more wet scrubbing purifying oil fume treatment technologies of advantage such as stable, that fire protecting performance is superior, forms such as that the structure of wet scrubbing oil fume secondary purifier is divided into is box, cyclone type, Venturi.First kind, box oil fume secondary purifier mainly is made of " S " type flue and the high-pressure nozzle that is located on " S " type flue, and they constitute multistage high-pressure spraying washing chamber.Oil flue waste gas enters clarifier spray washing chamber, fully collides, contacts, condenses through multistage high-pressure atomization liquid, and dehydration at last effluxes.

Second kind, the Whirlwind type oil fume secondary purifier is nested by inside and outside two cylinders and constitutes, and double wall top is provided with several high-pressure water nozzles.Oil flue waste gas enters with tangential direction from outer cylinder top, and spiral moves down fast between the inner/outer tube double wall, and high-pressure water nozzle constantly sprays water droplet, and wall, outer tube inner wall form uniform two-layer moisture film outer tube.The part water droplet also forms the dusty gas that water smoke moves down spiral between double wall and washs and humidification, to impel the constantly cohesion fast of small particle diameter grit, adheres on the moisture film thereby arrive outer tube inner wall under action of centrifugal force, discharges from the bottom of deduster.The moisture film of inner tank theca particularly for the grit of critical particle diameter, has certain clean-up effect under the effect of adhesion, extension.Purified gas enters the inner barrel spiral with tangential direction equally from the inner core bottom and rises, and further purifies and separates with aqueous vapor, after air-introduced machine enters chimney and emptying.

The third is the oil fume secondary purifier that is made of Venturi (convergent-divergent pipe), is provided with shower nozzle at the throat place.Oil flue waste gas is when its throat, and cigarette speed is the highest, at the inlet of throat water is sprayed in the flue gas equably, and swiftly flowing flue gas further is atomized into tiny water droplet with water, by anemostat flue gas is directly discharged then.

All correspondingly there are many weak points in above-mentioned three kinds of structures:

1, gas, moisture is not from thorough.Oil smoke is directly discharged oil smoke after spray oil removing, taste removal, do not carry out gas, moisture from, cause easily follow-up Corrosion of Pipeline.

2, exhaust resistance is big, the air draft weak effect.Because air-flow is easy to produce vortex flow in cylindrical shell, exhaust resistance is big, the air draft weak effect.

3, oily waste water also needs to handle again.Oil, the aqueous solution behind the spray washing are mixed in together, and during effluent, oily waste water could discharge after must handling through oil water separator.

Summary of the invention

The objective of the invention is to design a kind of gas, moisture from oil fume secondary purifier thorough, that deoiling effect is good.

In order to achieve the above object, the present invention adopts following technical solution: a kind of oil fume secondary purifier, comprise Venturi, inner core, urceolus and wash spray device, wherein, the wash spray device comprises water pipe, water pump, shower nozzle and washing soup storage bin, washing soup storage bin is located in the urceolus cavity of resorption, shower nozzle is located in the Venturi, inner core is suspended in the urceolus, the inner core upper port is in outside the urceolus, the inner core lower port is in the urceolus, it is characterized in that Venturi advances to be connected with urceolus epicoele snail, is provided with spiral type flow guide plates in the chamber between the inner core outside and the urceolus inboard.

Soot gas is when Venturi, oil, flavor ion and liquid medicine mist carry out strong collision, cohesion, the oil smoke quality increases, the soot particles size increases, the oil smoke surface is by moistening, proportion strengthens, air-flow is through speedup, diffusion, deceleration, expansion cooling simultaneously, the oil smoke that has water droplet enters cylindrical shell, in specific guide rail, under the air-flow effect of rotation at a high speed, the mixture of the soot particles and the aqueous solution is forced to centrifugal, drop to rapidly in the bottom wash soup storage bin along barrel, the gas that separates the back cleaning changes inner core over to and discharges.Realize that gas, moisture are from purpose thorough, that deoiling effect is good.
