Abstract

The utility model discloses a wet type dust remover, characterized in that; a shower nozzle which dusty air flows through is composed of a replaceable shower nozzle section (1), a tower body pool (7) connected outside, a hydraulic sealed overflow pipe (3), shutter-type water baffle demister (9), etc. Dusty air cuts in water in a certain speed and causes intense air-liquid agitation; the particulates in the air is collected by the water; the air purified is exhausted out of the tower after defogged by the demister and the water in the demister is provided by a water supply pipe (11); superfluous water is exhausted to fixed position of the overflow pipe via the hydraulic sealed overflow pipe, so that the water level keeps stable. The shower nozzle is a wearing part but can be replaced periodically. The pool connected with outside is used for cleaning dust deposition in the pool on time, which prevents the dust removing efficiency from effected by the excess dust deposition in the pool. The new shutter-type water baffle demister has excellent action. The wet type dust remover has the advantages of simple structure, easy maintenance management, stable running and low cost. The remover is applied in the industry of ceramics, building materials, stone carving, etc, and has good effect. The resistance of the wet type dust remover is 1000 pa.

Description

Novel wet scrubber

The novel wet scrubber of technical field is a kind of novel impingement washing scrubber.Its principle is: dust laden air pours in the water with the shower nozzle of certain speed through being arranged at tower body central authorities, shower nozzle is certain depth in water not, rely on the impact of air-flow to cause the fierceness of gas-liquid to stir, form foam, the inertia of mat particle and the humidification of water, particle in the gas is trapped in the water, by after the demist of water fender demister, discharge deduster through the air after the water washing.

The structural shape of the existing impingement washing scrubber of technical background exists certain shortcoming, makes deduster have its due dedusting effect by the parameter operation of design.For example: after the laying dust in the pond of deduster increases, must open cover plate for manhole cleaning laying dust, the time-consuming merit of taking often can not in time be cleared up, and efficiency of dust collection is reduced; The height of overflow pipe is provided with inaccurately, makes shower nozzle not have water depth to be higher or lower than design load, and the resistance of deduster is increased or the efficiency of dust collection reduction; Shower nozzle is an easily worn part, and the trimming of wearing and tearing back is difficulty very; 90 ° of water fender demisters of intrinsic 4 foldings, at its turning, very easily laying dust needs often cleaning etc.

Summary of the invention the utility model at the shortcoming that impingement washing scrubber exists, has been done the many places improvement, has made things convenient for maintenance management, and the service condition of deduster is well guaranteed, reaches the dust removing effects of expection.

The utility model is a kind of novel impact water bath wet scrubber (seeing figure), it is characterized in that: it is by dismountable import showerhead (1), (2) and the tower body pond (7), (8) that are connected with the external world, overflow pipe (3), (4), (5), water seal overflow cylinder (6), water inlet pipe (11), blind window dash template demister (9), (10), tower body (12), air outlet (13) is formed.、

Bottom, description of drawings tower body pond (7) is inside and outside connection, utilizes the partition wall (plate) (8) in pond to make the tower inner air and outer air isolate (during the deduster operation, being in negative pressure or barotropic state in the tower).At the bottom of the absolute altitude of dividing plate bottom in the absolute altitude of the overflow mouth of pipe (3).Be communicated with the setting in pond, make that the laying dust at the bottom of the removing tower is very easy to, thereby the efficiency of dust collection that has guaranteed deduster can not reduce because of the influence of the laying dust in the pond.

During the deduster operation, the absolute altitude place (predetermined shower nozzle does not have water depth) that must keep the water level in the tower being scheduled to.Because tower external and internal pressure difference, it is to realize by the water seal overflow pipe mouth of pipe is arranged on predetermined absolute altitude place.The water seal overflow pipe is made up of overflow pipe in the tower (3) and the outer overflow pipe (4) of tower.Overflow pipe is fixed in deduster overflow pipe manhole flange (5) and goes up the location.Outer overflow pipe (4) inserts in the outer water seal overflow cylinder (6) of tower, to guarantee that the unnecessary water yield is in time discharged outside the tower in isolation of tower inner air and outer air and the tower.Stable level is reliable in inert body of water seal overflow pipe, control tower.

Shower nozzle (1) is the core of gas, liquid, dirt energy exchange, is the easily worn part of deduster.In order to tear a compensation tower body open after shower nozzle is damaged and to use corrosion-resistant material to make.The manhole (2) that the utility model is designed to showerhead to have the shower nozzle (1) of two flanges of size and shower nozzle is installed.With big flange shower nozzle is fixed on the manhole flange and locatees.Little flange is used to connect outside airduct.In addition, utilize the shower nozzle manhole can check easily in the overflow pipe mouth of pipe (3) whether on the absolute altitude of designing requirement.If needed, can correct easily.

Shutter water fender demister is made up of 45 ° of shutters of polylith (9), positive and negative staggered laying.Separate with empty framework between two louvers.

Water fender demister after the improvement is respond well, has improved demister effect and cleaning cycle significantly.

This suitable novel deduster of the specific embodiment is simple in structure, is easy to maintenance management, stable, and cost is low.Be used for pottery, building materials, industries such as brick and tile, stone flour, stone carving all have effect preferably.The about 1000Pa of resistance.
