Abstract

The utility model discloses a kind of small-sized efficient waste incineration dedusting tar removing combination units, it is characterised in that: including being made with steel plate, square tube, angle steel, steel wire, heat-resisting filter cotton etc..Flue gas of refuse burning is entered the helical duct of cyclone dust collectors by air inlet, utilize the centrifugal sedimentation principle of downward spiral, when fluid is rotated with dust, the density of dust is higher than the density of exhaust gas, due to the centrifugal inertial force that high speed rotation generates, makes dust that relative motion occur in upward direction and fluid and fly away from central area.The successful application of the device, harm of the tar to cloth bag in refuse burning system flue gas emission will greatly be alleviated, reaching latest national standards for small refuse incinerator system flue gas emission, (" medical wastes incineration environmental health standards " (GB/T 18773-2008) and " dangerous waste incineration contamination control standard " (GB18484-2001) lays the foundation.

Description

Small-sized efficient waste incineration dedusting tar removing combination unit

Technical field

The utility model relates to a kind of garbage combustion devices, and specifically one is small-sized efficient waste incineration dedusting decokings Oil combination unit.

Background technique

Since China reformulates, has issued and implemented most severe since the dawn of human civilization " consumer waste incineration contamination control standard " (GB 18485-2014).Original method for landfill treatment has become history.World economy developed country is general to all kinds of rubbish All over burning disposal is used, incineration tail gas discharges after must being up to state standards after series of processes.

For current domestic Small-sized living garbage incinerator structure, emphasis to domestic waste incineration exhaust treatment system into Improvement is gone.It is well known that the accounting of plastic products is quite big at present in the generally existing house refuse in China.Plastics are being burnt Tar can be generated when burning, after tar enters bag filter with flue gas, is adhered on cloth bag, and the ventilative effect of cloth bag will soon be made Degradation, tar paste bag are difficult to clean off again, scrap so as to cause cloth bag.

Utility model content

Therefore, in order to solve above-mentioned deficiency, the utility model provides a kind of small-sized efficient waste incineration dedusting decoking herein Oil combination unit.The purpose of this utility model is that improving the tar occurred in existing Small-sized living garbage incinerator vent gas treatment The serious problems for pasting bag provide a kind of garbage incinerating tail gas dedusting tar removing combination unit, more perfectly extend making for cloth bag Use the service life.

The utility model is realized in this way a kind of small-sized efficient waste incineration dedusting tar removing combination unit is constructed, Be characterized in that: it includes steelframe, blast pipe, helical duct, a flue-dust retainer tangentially entered the wind, and is easy for below flue-dust retainer clear Except the ash door of collection ash；Flue gas carries under one's arms smaller dust and tar and continues to go upward to upper cone bucket, tar and part powder by discharge pipe The heat-resisting filter cotton that dirt is arranged by quarrel adsorbs；Remaining dust enters smoking box with flue gas, is discharged by smoke outlet；Resistance to heat filtering Cotton is mounted in hermatic door, can open hermatic door in due course and replace heat-resisting filter cotton；Entire combination unit is weldingly fixed on square tube On the steelframe of steel group weldering.

According to a kind of small-sized efficient waste incineration dedusting tar removing combination unit described in the utility model, it is characterised in that: Dust-laden exhaust gas by top blast pipe (it is tangential to enter, it is for the helical movement downwards by the constraint of helical duct wall.In inertial centrifugal Under power effect, larger grit is thrown toward wall and separates with air-flow, loses kinetic energy after hitting wall, by gravity along cyclone dust collectors tube wall Fall on the ash discharging hole of flue-dust retainer.The quality of the sealing element of cyclone dust collectors equipment is extremely important to the separating effect of dust, if Gas leakage occurs, then the operating path of dust-laden exhaust gas can change, and particle is separated with air-flow and is affected, especially in cone bottom position It sets, in case of gas leakage, dust can be further resulted in and raised again, into purified ascending air.

According to a kind of small-sized efficient waste incineration dedusting tar removing combination unit described in the utility model, it is characterised in that: It is hampered by cone bottom by purified gas, it is afterwards then from bottom to top for the helical movement near central axis, finally by along whirlwind The exhaust pipe of dust remover roof excludes.

According to a kind of small-sized efficient waste incineration dedusting tar removing combination unit described in the utility model, it is characterised in that: The discharge pipe is hollow steel pipe, connects upper cone bucket thereon.

According to a kind of small-sized efficient waste incineration dedusting tar removing combination unit described in the utility model, it is characterised in that: The oral area of upper cone bucket is provided with heat-resisting filter cotton, to be provided with outlet port in headwall, and equipped with close convenient for replacing filter cotton at any time Closure door.

According to a kind of small-sized efficient waste incineration dedusting tar removing combination unit described in the utility model, it is characterised in that: Flue gas after filtering enters smoking box, is then discharged by smoke outlet.

According to a kind of small-sized efficient waste incineration dedusting tar removing combination unit described in the utility model, it is characterised in that: Heat-resisting filter cotton is loaded in the frame welded with angle steel, and filter cotton is fixed with steel wire up and down.Heat-resisting filter cotton not only adsorbs Tar stops dust, can also obstruct Mars and scurry into bag filter and burn out cloth bag.

For the features such as garbage incinerating tail gas fume amount is big, tar content is high, it by conventional use of cyclone dust collectors and Dry filter is combined, and has not only been removed the grit in flue gas but also has been adsorbed the tar in flue gas.Consider that flue-gas temperature is higher, specially Door selects a kind of heat-resisting filter cotton.

The utility model has the advantages that the utility model discloses a kind of small-sized efficient waste incineration dedusting tar removings Combination unit, it is characterised in that: including being made with steel plate, square tube, angle steel, steel wire, heat-resisting filter cotton etc..Waste incineration Flue gas is entered the helical duct of cyclone dust collectors by air inlet, using the centrifugal sedimentation principle of downward spiral, when fluid is with powder When dancing dervish turns, the density of dust is higher than the density of exhaust gas, due to the centrifugal inertial force that high speed rotation generates, makes dust upwards Central area is flown away to relative motion occurs with fluid, the cyclone dust collectors of this programme setting mainly utilize the stalling characteristic By in flue gas larger grit and Mars separation, achieve the purpose that first dedusting and protect rear end bag filter in filter bag, prolong The service life of long filter bag.Larger grit and Mars are deposited in ash bucket, are periodically removed by opening ash door.Flue gas is carried under one's arms Smaller dust and tar continue to go upward to the heat-resisting filter cotton that upper cone bucket, tar and part dust are arranged by quarrel by discharge pipe Absorption.Remaining dust enters smoking box with flue gas, is discharged by smoke outlet.Heat-resisting filter cotton is mounted in hermatic door, can be in due course It opens hermatic door and replaces heat-resisting filter cotton.Entire combination unit is weldingly fixed on the steelframe of square hollow section steel group weldering.

The successful application of the device will greatly alleviate harm of the tar to cloth bag in refuse burning system flue gas emission, Reach latest national standards (" medical wastes incineration environmental health standards " (GB/T for small refuse incinerator system flue gas emission 18773-2008) lay the foundation with " dangerous waste incineration contamination control standard " (GB18484-2001).
