Abstract

The utility model relates to dust removal equipment used for removing the flue gas of an industrial boiler, which is particularly to suitable for a kiln with the amount of gas production of 10 ton per hour and high content of smoke and dust. The utility model is characterized in that water bath connected in series is used twice at least to remove dust, and then the dehydration is carried out. The utility model has the advantages of high dust removal efficiency which is up to 99.9%, simple structure, low cost, long service life, no need of maintenance and convenient dust removal. The removed dust is viscous and mushy, and is easy to carry away directly.

Description

Ma stone double flushing dust remover

The utility model relates to the smoke dust-removing equipment of Industrial Boiler, is specially adapted to below the steam production 10T/H fluidized bed furnace that smoke content is very high, coal-powder boiler and corresponding industrial furnace.

Its efficiency of dust collection of existing gallet water curtain dust collector only is about 90%, for the high fluidized bed furnace of smoke content, coal-powder boiler and corresponding industrial furnace, does not reach the soot emissions requirement of national regulation.Also have a kind of impulse type water bath deduster,, work as smoke content at 20000mg/Nm though efficiency of dust collection can reach 98% ³When above, just do not reach the soot emissions requirement of national regulation.CN90208090.3 " numb stone does not have the overflow bubble dust collector ", though efficiency of dust collection is high, the dedusting medium need be used foam.The common drawback of above-mentioned all kinds of dedusters is that dust can not directly be got rid of, and has increased devices such as the circulatory system, ashpit.

The purpose of this utility model is to improve efficiency of dust collection, is in particular smoke content and reaches 20000mg/Nm ³Above fluidized bed furnace, coal-powder boiler and corresponding Industrial Stoves provide a kind of deduster of multistage dedusting combination, and can make water, ash content from, dust can be discharged outside the deduster under the gravity effect automatically, water consumption few (water consumption is the dust water absorption), cost is low, need not maintenance, and the life-span is long, deduster simple in structure, that resistance is little.

Ma stone double flushing deduster described in the utility model, its shell are with numb one-tenth made of stones, and its operation principle is: water bath dust-removing is used at least twice series connection, and then dehydration.

Fig. 1 is an outside drawing of the present utility model in the accompanying drawing, Fig. 2 be Figure 1A to cross sectional plan view, Fig. 3 be Fig. 2 B to cutaway view, Fig. 4 is that Fig. 3 C is to cutaway view.

In Fig. 1,1 is air inlet, and 4 is the pond, and 8 is dehydrator, and 10 is draining valve, and 11 is overfall.

In Fig. 2,3 is shower room, and 7 is trunnion, and 9 are water seal, and 13 is exhaust outlet.

In Fig. 3,5 are stream ash slope, and 6 is vertical flue, and 12 for swashing the water cutter, and 14 are the water seal wall.

The course of work of the present utility model is such: flue gas enters deduster from air inlet 1, after carrying out the water bath dust-removing first time on the water surface in pond 2, flue gas enters shower room 3 shower, make bubble in the water-bath process for the first time wrap up in the dry ash of band all moistening after, on the water surface in pond 4, carry out water bath dust-removing second time, behind the second time water bath dust-removing, flue gas carries out shower through vertical flue 6, the required water of shower is supplied with by sharp water cutter 12, and flue gas enters trunnion 7 after the shower, arrives dehydrator 8 dehydrations again.Flue gas after dehydration enters air-introduced machine again, and the dedusting effect is arranged again in dehydration simultaneously.

Twice water bath dust-removing removes dust down, through flow ash slope 5 sink to the pond at the bottom of through ash-valve 10(both sides each one) discharge, the dust of discharge is thick.

The water that dehydrator 8 is deviate from from flue gas is discharged from water seal 9, and the water surface in two ponds 2,4 communicates with atmosphere, and overfall 11 guarantees that there is fixed level in its two pond, and makes air-introduced machine not be with water, and a water seal wall 14 is respectively established in two ponds, and deduster is not leaked out.

The utility model has the advantage of that it is multistage dedusting, the efficiency of dust collection height is specially adapted to the high boiler of dust content and industrial furnace, and efficiency of dust collection can reach 99.9%, and cost is low, and the life-span is long, need not maintenance, and the dust of discharge is thick-pasty, can directly transport.

Claims (3)

1, the deduster of the numb one-tenth shell made of stones of a kind of usefulness, mainly by air inlet 1, pond 2,4, shower room 3, stream ash slope 5, vertical flue 6, trunnion 7, dehydrator 8, water seal 9, ash-valve 10 compositions such as grade is characterized in that at least twice series connection use water bath dust-removing, dewater again.

2, deduster according to claim 1 is characterized in that with a dehydrator 8.

3, deduster according to claim 1 is characterized in that sloping 5 bottoms of described stream ash have two ash-valves 10 at least.
