Abstract

The utility model relates to a wet-type smoke prevention desulfuration dust collector, which is composed of a main body of a collector (1), a smoke inlet (2), a gas outlet (3), a demister (4), a dust collecting water tank (7) and a feeling port (8), wherein, the smoke inlet (2) is arranged on the side part of the main body of the collector (1); the smoke outlet (3) is arranged on the most upper end of the main body of the collector (1); the upper part of the main body of the collector (1) is provided with the demister (4) and the lower part is provided with the dust collecting water tank (7); the feeding port (8) is arranged on the side face of the dust collecting water tank (7); a sieve plate (6) is arranged on the lower end of a smoke inlet pipe (5) in the main body of the collertor (1), causing that smoke, liquid and solid can be uniformly mixed. The utility model has the advantages of higher desulfurizing and dust collecting efficiencies. The utility model is especially suitable for treating black smoke for hand feeding combustion equipment of a vertical boiler, an industrial kiln, etc.

Description

A kind of wet type dust remover capable of eliminating smoke and desulphation

The utility model relates to a kind of deduster, is specifically related to a kind of wet type dust remover capable of eliminating smoke and desulphation that makes dusty gas by water-bath.

The energy resource structure of China is based on coal, and the atmosphere pollution that fire coal causes is subjected to common concern, thereby the emphasis of China's prevention and control of air pollution is the smoke elimination of coal-fired flue-gas, desulfurization, dedusting.Now the dry type multi-tube dust cleaner efficiency of dust collection that generally adopts can reach more than 90%, but the smoke elimination ability is relatively poor and can not desulfurization.And all kinds of wet desulfurization dust-removing devices are as: spray, foam, moisture film, shaped Venturi dedusting device desulfurization and dedusting simultaneously, but desulfuration efficiency is low, and floor space is big, water consumption is high, thereby the scope of promoting the use of is restricted.In recent years, the storage water heater impingement washing scrubber is because of cost is low, simple in structure, water consumption is little and developed.Its structure mainly is made up of water tank (pond), water inlet pipe, outlet pipe and shower nozzle.Technical process is as follows: when the dusty gas with certain speed after air inlet pipe, sentence higher speed ejection at shower nozzle, water layer is produced percussion, changed the direction of motion of gas, grit is owing to inertia then continues by original direction motion, wherein most of grit is stayed in the water by water adhesion, some grit is still with gas motion in addition, with big stroke water droplet and foam mix form gas, solid, liquid three-phase and mix after, dusty gas is further purified, and gas is discharged from blast pipe after dewatering.The weak point of this device is: (1) desulfuration efficiency is low, can not eliminate smoke; (2) water level is required sternly, resistance increased when water level was high, and when water level hanged down, efficiency of dust collection was not high.

The purpose of this utility model provides a kind of smoke elimination, desulfurization, efficiency of dust collection height, and water level is required not tight wet type dust remover capable of eliminating smoke and desulphation.

The purpose of this utility model is achieved in that it is made up of deduster main body, air inlet, gas outlet, dog-house, collection gray water tank, demister, air inlet is at the sidepiece of deduster main body, the gas outlet is in the top of deduster main body, the top of deduster main body is demister, the bottom is the collection gray water tank, have dog-house in collection gray water tank side, be provided with one or more layers sieve plate in the air inlet pipe lower end of deduster body interior.Dusty gas enters the water through air inlet pipe from air inlet, big grit falls into collection gray water tank bottom, the grit of small particle diameter rises from water with gas, pass through sieve plate, form bubble at the eyelet place, make grit by water adhesion in bubble rising, diffusion, rupture process, sulfur dioxide in flue gas is diffused in the water, on sieve plate, form gas, liquid, solid three phase mixtures, gas is fully purified.

Eyelet center line on the above-mentioned sieve plate is vertical with the plate face, can be 30-50 ° with plate face tilt angle also.

The utility model compared with prior art has following advantage:

1. owing to increased sieve plate, mix, gas is fully purified, the efficiency of dust collection height so formed the gas, liquid, solid three-phase.

2. occupation area of equipment is little, and is simple in structure.

3. water consumption is few, and cost is low.

Below in conjunction with drawings and Examples the utility model is specified.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the sieve plate schematic diagram.

As shown in the figure, the 1st, deduster main body, the 2nd, air inlet, the 3rd, gas outlet, the 4th, demister, the 5th, air inlet pipe, the 6th, sieve plate, the 7th, collection gray water tank, the 8th, dog-house.Air inlet 2 is located at deduster main body 1 sidepiece, and gas outlet 3 is in the upper end of deduster main body 1, and demister 4 is at the deduster internal upper part, and the bottom is collection gray water tank 7, and dog-house 8 is in the side of collection gray water tank 7, and sieve plate 6 is the lower ends in air inlet pipe 5.

Dusty gas enters deduster from air inlet 2 during work, after air inlet pipe 5 is impacted the water surface, big grit falls into collection gray water tank 7 bottoms, little grit also falls into the water through the collision with sieve plate 6, gas returns in the deduster main body 1 through sieve plate 6, after demister 4 demists, is given vent to anger by purified gas and 3 to discharge, dog-house 8 is used for regulating the water level of deduster simultaneously in order to add alkaline matter.
