Abstract

The utility model relates to a spiral-flow water washing dust-removing and desulfurizing apparatus. The utility model is composed of a draught fan, a dust suction pipe, a stirring pool, a purifying tower, a purifying pool, etc., wherein, the draught fan and the dust suction pipe suck in smoke dust from the outlet of a chimney, and the purifying tower is provided with a vibration filter sieve inside. The smoke dust that is sucked in is directly exhausted into the stirring pool from the dust suction pipe, and under the action of an impulse impeller, the water stream rotates, tumbles and is fully adsorbed and merged with the smoke gas. The smoke gas that contains residual dust is filtered by the vibration filter sieve inside the purifying tower and rises up, and then a water baffle baffles the mist beads and water drops and absorbs dust; after purified, the gas is exhausted into the air. After the water inside the stirring pool flows into the purifying pool and the sediments inside are cleared, the water flows back into the stirring pool for recirculation. The utility model is reasonable in structure and low in cost, and practice verifies that the effectiveness ratio of desulphurization of the utility model reaches more than 98 percent.

Description

A kind of eddy flow rinsing type dust-removing desulfurating apparatus

The utility model relates to a kind of environmental protection equipment, particularly is applicable to the dust-removing desulfurating apparatus of smoke and dust treatment.

In present existing smoke contamination treating apparatus, water washing dedust or water curtain dedusting are adopted by increasing user because of its cost characteristics lower, simple in structure, easy to manufacture, easy to maintenance.But the water law dedusting also has some relatively to be difficult to the problem that solves, and for example, multiple flue dust all contains certain oil content, and is can not moment water-soluble; Because the water curtain dedusting is to carry out in the bigger air-flow of blower fan, so water curtain is pressed on one side by powerful air-flow easily, most soot dust granules contact absorption with current chance is few, and it is unclean to form dedusting; There is the sulfur-bearing composition list in some flue dust to take the water wet method short time to remove, therefore, makes the effect of rinsing type or water curtain style dedusting also beat very big discount.

The water washing dedust equipment that the purpose of this utility model is to provide a kind of chance that can make flue dust contact absorption with current to increase greatly not only can be accelerated flue dust and dissolve process in water, and help the desulfurizing and purifying of flue dust, improves dust removing effects.

The purpose of this utility model is achieved in that under the effect of blower fan the chimney flue dust directly enters through dust sucting pipeline and stirs the pond.This stirring pond is rectangle, and certain-length is arranged.One end in pond has an impulse impeller, be used to stir water in the pond and make it rotation and seethe, the other end of pond main body is communicated with the purifying column bottom, and the bottom of purifying column is designed a vibration filtering and sieved on horizontal plane, purifying column top is some blocks of shelves water plates, and the purifying column upper end is an exhaust outlet.

Be illustrated below in conjunction with embodiment and accompanying drawing.

In Fig. 1:

1, dust sucting pipeline exhaust outlet; 2, stir the pond; 3, flue dust moisture outlet; 4, impulse impeller; 5, fixed hub; 6, propeller shaft; 7, propeller motor; 8, vibration filtering sieve motor; 9, vibration filtering sieve connecting axle; 10, vibration filtering sieve; 11, purifying column; 12, access panel; 13, shelves water plate; 14, flue gas discharge opening; 15, purification water pool; 16, dust absorption fan; 17, dust sucting pipeline; 18, chimney; 19, throat dust shield.

As shown in the figure, when chimney 18 soot emissions, dust absorption fan 16 work, flue dust arrives dust sucting pipeline outlet 1 by throat dust shield 19 at fan action lower edge dust sucting pipeline 17 and enters stirring pond 2.An end has agitator arm 4 in the stirring pool 2, rotation under motor 7 band, and making that the current rotation is rolled in the stirring pool advances.Export 1 flue dust that enters under the effect of agitator arm 4 by dust sucting pipeline, the flue dust air-flow is with the current fusion of rolling, owing to stir and added the additive that promotes that sulfide and oiling decompose in the pond, the hydrone surface tension increases, under the current that impulse impeller 4 stirs roll bump, the granule dust of flue gas and hydrone can adsorb fully, sulfide in the exhaust gas dust is also deviate under the additive effect, and flue gas discharges to purifying column 11 from stirring pond outlet 3 in the water impact effect.Because purifying column 11 bottoms are vibration filtering sieve 10, make the dust granules that exports in the air-flow that enters purifying column 11 by the stirring pond obtain filtration, purification again like this.Because of shelves water plate 13 stops, the water smoke globule condenses into water droplet and falls after rise the air-flow of process vibration filtering sieve 10 in uphill process, and remaining dust also merges in water droplet, sieves 10 by vibration filtering and falls after rise to stirring the pond, enters in the air through purified gas.

Simultaneously, the current that stir in the pond 2 enter clarifier-tank 15, and dust granules precipitates in clarifier-tank and is eliminated, and the water recirculation after the purification enters stirs pond 2, the course of work of form so successively, going round and beginning again.
