Description
Technical field
This utility model is related to a kind of melting carbide waste-heat recovery device.
Background technology
China's calcium carbide industry there are about furnace of calcium carbide more than 1,000, and annual production occupies first place in the world, and China's carbide yield reaches within 2010
To 22,000,000 tons/year, China has become the country of carbide yield and consumption figure maximum in the world.
It is known that calcium carbide furnace gas have latent heat and the sensible heat of itself, profit is reclaimed for 4.5 ten thousand tons/year of furnaces of calcium carbide of separate unit
Use furnace gas heat energy, be equivalent to 7000 tons of standard coal of saving.If calculating, the whole nation is every with 22,000,000 tons of years of China's carbide production capacity
Year can save 330 ~ 3,500,000 tons of standard coal.
And the melting carbide temperature come out of the stove is up to 1800-1900 degree, its heat content is high, and heat is big；Carbide factory at present
In, molten condition carbide discharges furnace rear, places and leans on long-time natural cooling or air blast to force cooling and solidifying in atmosphere, this allows
A large amount of arbitrarily lost techniques of heat energy are irrational.Its major defect one is that the heat of solution released during melting carbide solidification is (latent
Heat) and solidify after temperature-fall period liberated heat (sensible heat) be not all recycled；One is that nature places cooling required time relatively
Long, low production efficiency；Again because solidification cooling procedure is carried out indoors, need larger construction area, strong using aerator
Refrigeration again consuming a large amount of electric energy air blast and take away carbide heat but.
For this partly larger heat of releasing when reclaiming melting carbide solidification, cooling, with energy-saving, abroad, especially
It is in the poor Japan of energy resources, has carried out years of researches and practice it is proposed that the technique of multiple recovery heat and setting
Standby, it is using direct heat transfer mode mostly, producing steam is used for generating electricity, heating etc. is used, and aforesaid way heat exchange efficiency is high, but to equipment
Processing, production process control requirement are higher, and arbitrfary point leakage part and will result in major accident.
Melting carbide waste heat recovery belongs to the ground zero stage at home, also occurs in that multiple thinkings at present, and one kind is to utilize
Wind quenching is granulated, and reclaims its part of waste heat using fluid bed；One kind is to change carbide cooling apparatus structure, using direct heat transfer mode
Recovery section carbide heat；One kind is to change carbide Cooker structure to utilize tunnel cave concept to reclaim carbide GOOD TASTE partial heat.
Above-mentioned melting carbide waste heat reclaiming process common feature: the waste heat of a recovery GOOD TASTE part, the part after solidification
Waste heat is still to diffuse in production environment, and two is that carbide is produced as digital process, refers to for heat recovery.
