Abstract

The utility model relates to a boiler deduster, particularly a composite venturi gneiss deduster. In a venturi tube, a multi-angle sprinkler head is arranged, and a casing is arranged outside the venturi tube. The utility model can be used alone, and the utility model does not need to be cooperated with a gneiss water-film deduster. The dedusting efficiency of the utility model can reach more than 99%, and the utility model has the advantages of low cost, small land occupation, acid resistance, alkali resistance and convenient use and maintenance, being extensively used for the dedusting of power station boilers and various industrial boiler flues.

Description

Dust remover

Dust-removing device for boiler, a kind of granite duster.

As device for eliminating smoke and dust, gallet water curtain dust collector, the Venturi tube gallet water curtain dust collector is extensive use on station boiler, Industrial Boiler, and its cost is low, and is relatively simple for structure, and acidproof, alkaline-resisting, dust removing effects is more stable.The Venturi tube of existing Venturi tube gallet water curtain dust collector must be used with water dust scrubber, and its dust removing effects is compared with electrostatic precipitator, also has certain gap, but latter's cost is than higher.

The purpose of this utility model be the design a kind of can the use separately, dust removing effects is better than existing various numb stone dust removal machine, can with the granite duster cheaply of electrostatic precipitator one's deceased mother U.S..

The granite duster of the utility model design includes Venturi tube, it is characterized in that Venturi tube ［ 3 ］ outside is with that the bottom of garden cylindricality or rectangle communicates with the bottom of Venturi tube, gas outlet ［ 4 ］ up or the outer tube ［ 5 ］ of side top, the throat in the Venturi tube ［ 3 ］ is provided with fountain head ［ 1 ］ and ［ 2 ］ of different angles water spray.Outer tube ［ 5 ］ bottom sides also has the ash discharging hole ［ 6 ］ of water seal.

The granite duster of the utility model design is a kind of compound venturi scrubber, general Venturi tube throat has only a fountain head ［ 1 ］, design of the present utility model has increased the fountain head ［ 2 ］ of different angles, having increased water contacts with flue dust, the flue gas that enters Venturi tube is by bust and the acute variation that rises enter outer tube ［ 5 ］ significantly, further strengthened the contact of dirt water, utilize dirt, the gentle weight difference of water, the water of band dirt falls into bottom water, discharge by ash discharging hole, reach the dedusting purpose.The outstanding advantage that is different from existing Venturi tube dedusting is that the compound venturi granite deduster of the utility model design can use separately, and dust removing effects is high especially, can reach more than 99%, not only be better than the Venturi tube water dust scrubber, even than electrostatic precipitation better effects if, and original shaped Venturi dedusting device can not use separately, can only cooperate with gallet water curtain dust collector.

The granite duster of the utility model design, cost is low, and floor space is few, can be used for negative pressure, and the malleation effect is better.

The structure chart of a kind of granite duster that accompanying drawing designs for the utility model, there are fountain head ［ 1 ］ and ［ 2 ］ in the interior throat of Venturi tube ［ 3 ］, Venturi tube ［ 3 ］ outlet at bottom feeds the outer tube ［ 5 ］ of garden cylindricality, there is gas outlet ［ 4 ］ the side top of outer tube ［ 5 ］, outer tube ［ 5 ］ bottom sides has the ash discharging hole ［ 6 ］ of water seal, ash-laden gas enters Venturi tube ［ 3 ］ from gas approach ［ 7 ］, fountain head ［ 1 ］ and ［ 2 ］ of multi-angle water spray, the water of ejection makes the flue dust rapid subsidence, fall into bottom water, dust is discharged by bottom ash discharging hole ［ 6 ］, flue gas is the speed change bust also, enter outer tube ［ 5 ］ again, discharge the gas outlet of portion ［ 4 ］ from it, dirt is reached efficiently with gas separate with jumping through 180 ° sharp falls.

It is low that the compound venturi granite deduster of the utility model design has kept the granite duster cost, acidproof, alkaline-resisting advantage, efficiency of dust collection is more much higher than gallet water curtain dust collector, also is different from the Venturi tube gallet water curtain dust collector, Venturi tube must cooperate with water dust scrubber, it can use separately, takes up an area few, easy to maintenance, efficiency of dust collection but reaches more than 99%, even be better than electrostatic precipitator, and be used for the multiclass boiler dusting, obtain promising result.

Claims
