Description
Technical field
The present invention relates to a kind of coking environmental protecting device technical fields, are specially a kind of energy conservation and environmental protection coking equipment.
Background technology
Coking refers to that raw coal high-temperature retorting in the case where completely cutting off air conditions is heated to 1000 DEG C or so, passes through thermal decomposition and coking
Generate the technical process of coke, coke-stove gas and coking chemistry product.Smelter coke phosphorus content is high, and the porosity is high, and intensity is big（It is special
It is not elevated temperature strength）, it is the important fuel of blast furnace ironmaking and the proppant and raising agent of reducing agent and entire blast furnace stock column.
The coke-stove gas calorific capacity of coking by-product is high, is the excellent gas fuel of open hearth and heating furnace, is weight in integrated iron and steel works
The energy component wanted.Coking chemistry product is important industrial chemicals.Therefore coking production is a weight of modern steel industry
Want link.
As the industry of domestic and world steel is grown rapidly, the demand sharp increase to coking product, investment rises gradually day
Temperature, industry production capacity are expanded rapidly, but coking industry resource consumption is high, and production discharge is big, particularly harmful substance in emission
It is more, the serious wasting of resources and environmental pollution are caused, immense pressure is brought to national economy sustainable health development, so as to also hinder
The fast development of coking industry is hindered.
In traditional coking process, coke-stove gas generates high-temp waste gas by flue, accumulation of heat after burning in the combustion chamber
Room, after the part Exposure degree of exhaust gas, is directly discharged to by chimney in air by checker brick after a series of flues, these are high
The direct discharge of wet body causes environment destruction, accelerates greenhouse effects, at the same these high-temp waste gas contained it is a large amount of
Thermal energy also by wasting in vain.
A kind of transverse pipe initial cooler cooled down to coke-stove gas disclosed in Chinese patent 200710051923.X, bag
Primary cooler housing is included, epimere spray is fixed in housing and shines pipe and is sprayed with hypomere and shines pipe, is sprayed in hypomere and is provided with disconnected tower above solarization pipe
Disk controls the condensate liquid of primary cooler epimere and spray to shine liquid and directly led out without the hypomere of primary cooler, spray is avoided to shine liquid and cold
Lime set flows through primary cooler hypomere and absorbs the cold of hypomere heat exchanger tube, mitigates the thermic load of primary cooler low-temperature zone, and reduces simultaneously
The dosage of water at low temperature to reduce cost consumption, improves heat exchange efficiency of the heat exchanger tube to coal gas.But coke-stove gas heat is still
It is not effectively recycled and is utilized, while need to consume substantial amounts of cooling medium.
Chinese patent CN102478232A discloses a kind of recoverying and utilizing method of coke oven flue heat energy from waste gas, and this method is
Bypass flue by flue collector is set, heat pipe evaporator and air-introduced machine be installed successively on bypass flue, heat pipe evaporator is by coke
Fume afterheat in stove stack gases absorbs to heat cold medium, is allowed to ebullition, gasification and generates steam, for producing or living,
Exhaust gas after recovery waste heat leads back flue collector by air-introduced machine, is sent into chimney and is discharged in air.The system rate of recovery is low, structure is multiple
Miscellaneous, performance difficulty.
It is unable to that continuous production coke, environmental pollution be larger, thermal energy cannot cycle profit since traditional coke oven for iron exists
With, maintenance cost is high the defects of, therefore, be badly in need of it is a kind of it is simple in structure, can efficient circulation using coke oven exhaust gas energy conservation and environmental protection refine
Burnt equipment.
