Description
Technical field:
The utility model relates to the environment protection equipment technical field, is specifically related to a kind of furnace of calcium carbide residual neat recovering system.
Background technology:
Calcium carbide can produce a large amount of flue gases when furnace of calcium carbide is discharged, carry a large amount of carse, medium and small dust in the flue gas, carries a large amount of heat energy in the flue gas simultaneously.The furnace of calcium carbide fume recovery system adopts the single-stage dedusting technology more at present, promptly adopt bag dust collector to carry out the single-stage dust removal process, the problem that this system exists is the part dust that can only remove in the flue gas, and the pollution that is caused is still very serious, wastes a large amount of heat resources simultaneously.
Summary of the invention:
The utility model will provide a kind of furnace of calcium carbide residual neat recovering system, with the problem of seriously polluted, the waste heat resource that overcomes that prior art exists.
For overcoming the problem that prior art exists, the technical scheme that the utility model provides is: a kind of furnace of calcium carbide heat recovery system, comprise furnace of calcium carbide 1, bag dust collector 5, its special character is: also comprise the waste heat boiler 4 that is connected with bag dust collector 5, also be provided with the industrial steam outlet on the waste heat boiler 4, between furnace of calcium carbide 1 and waste heat boiler 4, be sequentially set with gravity and high-temperature cyclone dust extractor assembly 2 and hot-blast stove 3; Also be provided with hot blast tunnel cave 6, the exhaust outlet of hot blast tunnel cave 6 and waste heat boiler 4 join.
Compared with prior art, the utility model has the advantages that: the flue gas that produces from furnace of calcium carbide directly after gravitational precipitator and high-temperature cyclone dust extractor carry out dedusting, is delivered to waste heat boiler; And the high temperature calcium carbide that furnace of calcium carbide produces is delivered to the hot blast tunnel cave and is carried out recuperation of heat earlier.Not only can remove the carse, medium and small granule dust in the flue gas effectively, make fume emission reach discharging standards.Simultaneously can save a large amount of heat resources.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Description of reference numerals is as follows:
The 1-furnace of calcium carbide; 2-gravity and high-temperature cyclone dust extractor assembly; The 3-hot-blast stove; The 4-waste heat boiler; The 5-bag dust collector; 6-hot blast tunnel cave.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is elaborated.
Referring to accompanying drawing, a kind of furnace of calcium carbide Trinity residual neat recovering system, comprise furnace of calcium carbide 1, bag dust collector 5, the waste heat boiler 4 that is connected with bag dust collector 5, waste heat boiler 4 is provided with the industrial steam outlet, be sequentially set with gravity and high-temperature cyclone dust extractor assembly 2 and hot-blast stove 3 between furnace of calcium carbide 1 and waste heat boiler 4, also be provided with hot blast tunnel cave 6 between furnace of calcium carbide 1 and waste heat boiler 4, the exhaust outlet of hot blast tunnel cave 6 and waste heat boiler 4 join.
A large amount of flue gases that furnace of calcium carbide 1 produces, the gravitational precipitator that is delivered to earlier in gravity and the high-temperature cyclone dust extractor assembly 2 carries out primary dust removing, removes＞the 50um powder dust particle; High-temperature cyclone dust extractor in gravity and high-temperature cyclone dust extractor assembly 2 carries out two-stage dust removal again, remove＞10um,＜the 50um powder dust particle; Flue gas behind the two-stage dust removal is delivered to hot-blast stove 3, through an air distribution, fully burns the CO in the flue gas, makes flue-gas temperature be reduced to 600 ℃-800 ℃ through the secondary air distribution again, delivers to waste heat boiler 4 and carries out heat exchange, and flue-gas temperature is controlled at 200 ℃; Go out kiln gas (CO gas fully reclaims) and deliver to bag dust collector 5, carry out 3-stage dust-removal, remove＞0.2um,＜10um powder dust particle makes fume emission reach discharging standards.
Produce the acetylene stones sensible heat up to 2000 ℃ when calcium carbide is come out of the stove, it is interior airtight with calcium carbide pot the high temperature calcium carbide to be introduced hot blast tunnel cave 6, under the air blast effect, dried air is blasted hot blast tunnel cave 6 carry out the sensible heat exchange with the high temperature calcium carbide.According to user's needs, but the gas of production different temperatures is delivered to waste heat boiler 4 then, and waste heat boiler 4 is provided with the industrial steam outlet, generates industrial steam, uses for the user.
