Description
Technical field
The utility model belongs to the coking coke oven of a kind of continous way production metallurgy Jiao and foundry coke.Be particularly related to the coke oven that a kind of continuous production has vertical pipe type coking chamber structure.
Background technology
At present, the coke oven that in coking, coking enterprise, uses the vertical mechanical coke oven and build by laying bricks or stones mostly by refractory materials.Its structure is varied, can be divided into two kinds of internal heat type and external-heats from combustion system, internal heat type stove wherein, as various box coke ovens, but because it is long to exist the coking cycle, the defective that production efficiency is low, raw coal serious waste of resources, the byproduct rate of recovery are low etc. is difficult to overcome, thereby be subjected to country and ban.And in recent years, because box less investment, people carry out a large amount of improvement to box coke oven, to satisfy environmental protection, to reduce the resource consumption requirement, the interconnection type of recovery coke oven occurred not having, and have made moulded coal interconnection type coke oven etc. firm by ramming.So various clean interconnection type coke ovens have obtained very big development.As Chinese patent application number is 03215067.9 " a kind of heat accumulating type clean casting coke oven ", comprise the body of heater that constitutes by a plurality of fireholes, each firehole contains the coking chamber and the combustion chamber of communicating with each other by flue, be provided with the exhaust gas emission flue that communicates with the combustion chamber in the furnace wall between each firehole, furnace wall upper face in partition surface in the combustion chamber and the coking chamber is made the convex-concave shape, and at the bottom of combustion chamber laying grid gitter brick, improve the heat storage capacity of whole body of heater, satisfy the long needs of foundry coke coking time.And make moulded coal interconnection type coke oven firm by ramming is to have increased to make transportation of coal, briquette and shove charge firm by ramming on the basis of above modified form coke oven, and the coke pushing mechanical means of the discharging of the coke.Long for the above-described coking cycle, the defective that production efficiency is low still exists; Owing to increased a large amount of equipment such as dedusting, desulfurization, waste heat boiler and generating in the fume exhaust system coke oven outside, thus aspect the environmental protection and the minimizing wasting of resources again with very big technical progress.
External-heat Coke Oven Proper volume is little, and the coking cycle is short, and raw coal less wastage, byproduct easily can be received and can continuous production, more and more are subject to people's attention.As Chinese patent application number is 03211278 " a kind of interior-external-heat upright carbonization furnace that is applicable to bottle coal coking ".Charring furnace is a vertical heater, coking chamber is a Rotary-table, and the coking chamber zygomorphy is provided with the internal heat type combustion chamber, and there is the retaining firebrick inside, internal heat type combustion chamber, one side of combustion chamber is provided with burner, and each internal heat type combustion chamber is provided with two exhaust outlets on the partition wall of internal heat type combustion chamber and coking chamber; Be provided with the external-heat combustion chamber of auxiliary heat supplying on top, internal heat type combustion chamber, the body of heater top is provided with auxiliary coal bin, and bottom of furnace body is the coke discharging groove, is provided with the furnace retaining ironware around body of heater.Its material moves smooth and easy in stove, and nothing gets stuck, material suspension phenomenon, works well in the stove.Good permeability material homogeneous heating in the stove, rate of heating are fast.But the coke that refining is good may not fall in operational process in advance, forms blackhead Jiao, influences quality product, causes the wasting of resources.And for example Chinese patent application number is 200320111095 " built-up type Formed Coke Furnace ".It belongs to the external-heat Formed Coke Furnace, comprises the combustion chamber of coking chamber and coking chamber both sides, at the bottom of a slope is arranged at the coking chamber bottom, a sealing partition wall is arranged between coking chamber and the combustion chamber wherein, is provided with gas combustion apparatus in side wall of combustion chamber.Make the interior formed coke molding mass of coking chamber realize the destructive distillation of real meaning, the raw material of having avoided the internal heat type destructive distillation to cause burns and loses and the spontaneous combustion of fugitive constituent and the atmospheric pollution that the tar burning forms, uniformity of temperature profile in the coking chamber, the formed coke steady quality, blackhead Jiao etc. can not occur, and the dry distillation gas in the coking chamber is easy to reclaim.The combustion chamber is divided into the gas combustion apparatus that several isolation burning zones that are interconnected and each are isolated the corresponding level of burning zone, the setting of this structure can with in the combustion chamber from vertically by the temperature subregion, and can implement to it at any time.Correspondingly can carry out subregion, and be divided into dryer section, preheating section, retort section and the stewing section of heat etc. thus the charing room temp.Can guarantee formed coke coking quality.Although above-mentioned vertical coke oven has been obtained many technical progress.And exist common deficiency be: 1, material is dosed by the top of coke oven, though be intermittently reinforced, opening reinforced part flue dust and the obnoxious flavour eliminating that always will have, influence environment and pollutes; 2, the positions in coke furnace carbonization chamber such as described dryer section, preheating section, retort section and the stewing section of heat are relative variations, and the waste gas such as incendiary carbonic acid gas, carbon monoxide and sulfurous gas of pyrogenous coal gas, the stewing section of heat, and the moisture of pre-thermogenesis or the like concentrates in the coking chamber, for the fume emission treatment capacity of coke oven is big, as the device and the ability of the non-processor flue gas of coke oven own.3, extracting cleaning coal gas still needs to carry out equipment such as desulfurization processing, and also can cause secondary environmental pollution in treating processes.Will increase many environmental protection equipments and a large amount of investments.4, the waste heat of coking by coke oven fails to be utilized better.
Summary of the invention
