Description

A kind of composite machine wet type fume purifier of fume

The utility model discloses a kind of efficient composite machine wet purifying decice of administering of catering trade discharging oil smoke that can be used for.

Because the issuing and implementation GB18483-2001 " cooking fume discharge standard " (trying) of country, the discharging of control cooking fume has promoted the progress of technology for cooking fume control to the pollution of atmosphere.At present, it is machinery or wet type substantially that the existing fume purifier of fume in market destatics formula, and the general structure of mechanical type fume purifying is simpler, and purification efficiency is low; Though wet type can have greater efficiency, but some product structures can not make oil smoke contact with cleaning solution, mix fully, thereby can not keep higher oil smoke to remove efficient, and the flue gas after handling is not generally considered efficiently to remove to contain wet composition, often cause the ventilation shaft at rear portion and blower fan " band water ", stop up, normally use thereby influence cleaning equipment.

The purpose of this utility model is the deficiency that exists in the said goods technology, a kind of composite machine wet type fume purifier of fume is provided, can solve the problem of gas-liquid contact reaction better, improve oil smoke and remove efficient, and adopted multistage reliable demist dehydrated structure, guaranteed long-term, the normal operation of cleaning equipment.

The technical solution of the utility model partly is made up of cyclonic separation part, gas-liquid injection hybrid separation part and mechanical dehydration, and three parts are combined as a square box.

The purpose of this utility model is achieved in that purifier square box left side is cyclonic separation part and gas-liquid injection hybrid separation part, and the centre has dividing plate and right side mechanical dehydration partly to separate, and the dividing plate bottom opening is communicated with cleaning solution.Left side central portion is equipped with the cyclone separating tube of configuration tangent air inlet, the welding of cylinder inwall has the separation gusset of certain altitude, the eddy flow plate is equipped with on cylinder top, and the spraying cleaning solution nozzle is loaded under the eddy flow plate, is connect by pipeline outlet box external use flexible pipe and circulating-pump outlet; Be the gas-liquid separation tube on the eddy flow plate, inwall also is equipped with the separation gusset; It on the gas-liquid separation tube cover plate that has circular hole; Be that passage is communicated with the right side on the cover plate.Right side top board and right side are supported the cover plate installation shaft and are held, the assembling power transmission shaft, and power transmission shaft bottom assembling impeller, assembling belt pulley in power transmission shaft top is formed driving-chain by V belt and motor pulley; Motor is fixed on the casing outside by bearing.Right side central is equipped with the air-out cylinder that configures the air port.Lower box is equipped with overflow pipe and filling pipe; Delivery pipe is equipped with in the bottom half perforate.Detergent circulator is loaded on the partition space on the box bottom, and the pump inlet pipe inserts bottom half.

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing is the vertical section structure schematic diagram of embodiment.

In the accompanying drawing illustrated embodiment, composite machine wet purifying decice square box 1 is divided into left and right sides two parts by dividing plate 21, the left side: tangent air inlet 2 and cyclone separating tube 3 assemblings; The cyclone separating tube inwall separates the eddy flow plate 5 of the middle perforate of gusset top assembling according to the equidistant weld separation gusset 4 of circumference; Gas-liquid separation tube 6 is assembled according to cabinet wall in eddy flow plate top, the also equidistant weld separation gusset of gas-liquid separation tube inwall; Have circular holes in the middle of the cover plate 7 on it, casing top is divided into every a gas channel with the support cover plate 14 of the same horizontal level in right side.The casing bending top board on right side and the equal perforate rigid bearing 11 of support cover plate are by bearing assembling power transmission shaft 10; Power transmission shaft top is equipped with belt pulley and is connect by V belt 12 and motor 13 belt pulleys, bottom assembling gas-liquid centrifugation impeller 15; The certain distance assembling has the air-out cylinder 17 of tangential air outlet 18 under the impeller.Overflow pipe 22, filling pipe 23 are contained in lower box, 3 upright contour uncovered laying respectively in two side box bodies and the cyclone separating tube of overflow pipe, and casing is drawn in outlet, washs the liquid level stabilizing unanimity in order to guarantee the casing wash-in.Cleaning solution cyclic spray system is made up of with nozzle 8 circulating pump 19, flexible pipe 16, cyclic spray pipe 9, circulating pump is loaded on the partition space on the box bottom, the pump inlet pipe inserts under the bottom half washing liquid level, outlet connects flexible pipe, flexible pipe connects the cyclic spray pipe that enters casing, the eddy flow plate is passed in the playpipe lower end, and nozzle is installed.Bottom half installing wastewater discharge pipe 20.

The course of work of composite machine wet type fume purifier of fume is as follows: the pending oil smoke that produces in catering trade culinary art, the process is tangentially introduced from purifier casing left side air inlet, be forced to rotation at cyclone separating tube, oil droplet, particle than major diameter, severe are thrown to the cylinder inboard wall face when concentrating, stop downward earial drainage at the separated gusset of inner wall area coalescence; The flue gas of initial gross separation moves upward, and mixes with the cleaning solution of nozzle ejection, and minuteness particle, pernicious gas in the flue gas are captured, and so far flue gas has passed through machinery, wet type secondary purification.Flue gas behind the secondary purification is more upwards by demist eddy flow plate, be the mixed process again of vaporific cleaning solution and harmful substance, flue gas is forced rotation once more through the eddy flow plate, liquid mist in the gas is separated, and gas-liquid separation tube inwall thereon concentrates, the separated gusset of drop stops downward earial drainage, finishes the isolation of purified of another level; Purify flue gas again and arrive casing top, right side by the negative pressure central suction that the impeller rotation causes through casing upper air passage, flue gas carries out efficient isolation of purified under stronger centrifugal action, isolated drop imports the cleaning solution of bottom half along the downward earial drainage of cabinet wall.Purge gas is discharged through the tangential air outlet of air-out cylinder, enters atmosphere.The cleaning solution of nozzle ejection is supplied with closed cycle by the road by the circulating pump of lower box installing; Bottom half cleaning solution liquid level is by upright uncovered control on the overflow pipe; Moisturizing, input washing agent are added by filling pipe.Because above multi-stage separation goes out the floating liquid level of a greasy dirt part in the flue gas, moisturizing regularly can be discharged from overflow pipe; With the waste liquid of cleaning solution reaction formation flocculate, can regularly open delivery pipe and discharge processing.

Composite machine wet type fume purifier of fume makes the soot gas that enters through one-level wet type gas-liquid mixed, captures oil droplet, minuteness particle; Separate through two-stage centrifugal, adopt the eddy flow plate technique to remove mist of oil, water smoke, pass through the powerful mechanical centrifugation of one-level again, reach the requirement of efficient purification.This device oil smoke is removed the efficient height, and floor space is little, and power attenuation is low, and operational management is easy, satisfies the discharging standards requirement.
