Abstract
The utility model relates to the technology field of environmental protection equipment, particularly to a calcium carbide furnace three-stage dust-removal system, aiming to solve the problems in the prior art that only part of dust in the fume can be cleaned and fume discharge can not meet national discharge standard. The calcium carbide furnace three-stage dust-removal system comprises an induced draft fan, a bag-type dust collector connected with the induced draft fan, a gravity dust collector and a high temperature cyclone dust collector that are sequentially connected with a calcium carbide furnace, a water sealed fume exhaust, a hot-blast furnace, an exhaust-heat boiler, and an air drying chamber connected with the bag-type dust collector. The calcium carbide furnace three-stage dust-removal system provided in the utility model adopts three-stage dust-removal technique for the first time to completely clean the coarse, intermediate and fine granular dust in the fume, so that the fume discharge meets national discharge standard; and can ensure normal combustion at the same time.
Description
Affiliated technical field:
The utility model relates to the environment protection equipment technical field, is specifically related to a kind of furnace of calcium carbide 3-stage dust-removal system.
Background technology:
Calcium carbide can produce a large amount of flue gases when discharging from furnace of calcium carbide, carry a large amount of carse, medium and small dust in the flue gas.The pollution that it causes is very serious, belongs to the key object in the environmental improvement.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, especially under the high-temperature flue gas environment, is difficult to reach national standard limit of smog release.
Summary of the invention:
The utility model will provide a kind of furnace of calcium carbide 3-stage dust-removal system, and with the part dust in the flue gas can only removed that overcomes that prior art exists, fume emission does not reach the problem of discharging standards.
For overcoming the problem that prior art exists, the technical scheme that the utility model provides is: a kind of furnace of calcium carbide 3-stage dust-removal system, comprise air-introduced machine 8 and the bag dust collector 7 that joins with air-introduced machine 8, its special character is: also comprise the gravitational precipitator that joins successively with furnace of calcium carbide 1 and high-temperature cyclone dust extractor assembly 2, water seal smoke ejector 3, hot-blast stove 4, waste heat boiler 5, air drying chamber 6, air drying chamber 6 joins with bag dust collector 7.
Compared with prior art, the utility model adopts the 3-stage dust-removal technology first, thoroughly removes the carse, medium and small granule dust in the flue gas, makes fume emission reach discharging standards, can guarantee that burning is normal simultaneously.
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-gravitational precipitator and high-temperature cyclone dust extractor assembly; 3-water seal smoke ejector; The 4-hot-blast stove; The 5-waste heat boiler; The 6-air drying chamber; The 7-bag dust collector; The 8-air-introduced machine.
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 3-stage dust-removal system, comprise with furnace of calcium carbide 1 and joining, tactic gravitational precipitator and high-temperature cyclone dust extractor assembly 2, water seal smoke ejector 3, waste heat boiler 5, air drying chamber 6, air drying chamber 6 joins with bag dust collector 7 and air-introduced machine 8, water seal smoke ejector 3, waste heat boiler 5, air drying chamber 6, bag dust collector 7 and air-introduced machine 8, air-introduced machine 8 is connected to the emptying chimney.Be connected with hot-blast stove 4 between water seal smoke ejector 3 and the waste heat boiler 5
During work, the gravitational precipitator that a large amount of flue gases that produce when calcium carbide goes out furnace of calcium carbide 1 drain in gravitational precipitator and the high-temperature cyclone dust extractor assembly 2 carries out primary dust removing, removes＞powder dust particle of 50um; High-temperature cyclone dust extractor in gravitational precipitator and high-temperature cyclone dust extractor assembly 2 carries out two-stage dust removal, remove＞10um,＜powder dust particle of 50um; Flue gas behind the two-stage dust removal is delivered to hot-blast stove 4, 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 5 and carries out heat exchange, and flue-gas temperature is controlled at 200 ℃; Go out in the kiln gas CO gas after fully reclaiming, deliver to bag dust collector 7, carry out 3-stage dust-removal, remove＞0.2um,＜powder dust particle of 10um, make fume emission reach discharging standards.
