Abstract
The utility model relates to the technology field of environmental protection equipment, specifically to a CO recovery system for a calcium carbide furnace, aiming to solve the problems in the prior art including potential safety hazard and influence on the service life of boilers and bag-type dust collectors. The CO recovery system comprises a calcium carbide furnace, an exhaust-heat boiler, and a hot-blast furnace, wherein the air inlet port of the hot-blast furnace is connected with the smoke exhaust port of the calcium carbide furnace, and the air outlet port of the hot-blast furnace is connected with the exhaust-heat boiler. The CO recovery system for the calcium carbide furnace provided in the utility model has the following advantages of: (1) complete CO combustion, so as to basically solve the potential safety hazard; (2) more uniform heating surface, so as to improve the thermal efficiency of the exhaust-heat boiler; (3) reduced flue gas temperature to 200DEG C, so as not to burn out the bag-type dust collectors; and (4) the remarkably reduced tar oil crystallization on the boiler wall, so as to prolong the service life of the boilers.
Description
Affiliated technical field:
The utility model relates to the environment protection equipment technical field, is specifically related to a kind of CO recovery system of furnace of calcium carbide.
Background technology:
Because calcium carbide can produce a large amount of flue gases when coming out of the stove, and contains a large amount of CO gas and the exhaust gas dust of variable grain in the flue gas, can produce potential safety hazard to waste heat boiler.The domestic method of taking is that the flue gas that furnace of calcium carbide is discharged directly is delivered to waste heat boiler at present, enters atmosphere through bag dust collector again.The problem of its existence is: CO can not fully burn, and potential safety hazard can not be got rid of; Flue-gas temperature is too high, burns out bag dust collector easily; The boiler wall is easy to generate the tar crystallization, influences boiler service life.
Summary of the invention:
The utility model will provide a kind of CO recovery system of furnace of calcium carbide, potential safety hazard is arranged, influences the problem in boiler and bag dust collector service life with what overcome that prior art exists.
For overcoming the problem that prior art exists, the technical scheme that the utility model provides is: a kind of CO recovery system of furnace of calcium carbide, comprise furnace of calcium carbide 4, waste heat boiler 2 and bag dust collector 1, its special character is: also comprise hot-blast stove 3, the exhaust opening of the air inlet of hot-blast stove 3 and furnace of calcium carbide 4 joins, and the gas outlet of hot-blast stove 3 and waste heat boiler 2 join.
Compared with prior art, the utility model has the advantages that: the CO sufficient combustion has fundamentally solved potential safety hazard; Heating surface is more even, has improved the thermal efficiency of waste heat boiler; Flue-gas temperature has been reduced to 200 ℃, can not burn out bag dust collector; The tar of boiler wall generation simultaneously crystalline polamer greatly reduces, and obtains the service life of boiler prolonging.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Description of reference numerals is as follows:
The 1-bag dust collector; The 2-waste heat boiler; The 3-hot-blast stove; The 4-furnace of calcium carbide.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is elaborated.
Referring to accompanying drawing, a kind of CO recovery system of furnace of calcium carbide comprises with furnace of calcium carbide 4 and joining, tactic hot-blast stove 3, waste heat boiler 2, bag dust collector 1.The exhaust opening of the air inlet of hot-blast stove 3 and furnace of calcium carbide 4 joins, and the gas outlet of hot-blast stove 3 and waste heat boiler 2 join.
The concrete course of work is: the flue gas that contains CO that furnace of calcium carbide 4 produces is transported to hot-blast stove 3 and joins wind one time through the heating gas nozzle, in hot-blast stove 3, fully burn, flue-gas temperature is about the 1300-1400 degree, join the cooling of secondary wind through the heating gas nozzle again, flue-gas temperature is controlled at about 600 degree, and input waste heat boiler 2 carries out heat exchange.Fully burn the CO in the flue gas, make flue-gas temperature be reduced to 800 ℃ from 1400 ℃, be delivered to waste heat boiler 2 after the heat exchange, use kiln gas and be controlled at 200 ℃, enter atmosphere through bag dust collector 1 again by the secondary air distribution.
