Abstract
A dry quenching type coal briquette carbonization furnace is further provided with a main flue, branch flues and upper flues, wherein the upper flues are arranged at the top of a furnace body, the branch flues are arranged in two lateral walls in the middle of the furnace body, and the main flue is arranged above the furnace body. The main flue is respectively communicated with the branch flues and the upper flues which are connected with the branch flues through channels with gate plates. By means of the carbonization furnace, when the temperature in the branch flues is overhigh, the gate plates are opened to enable smoke in the branch flues to enter the upper flues and to be quickly discharged through the upper flues and the main flue. Therefore, the temperature in the branch flues can be effectively reduced, and the problem that the overhigh temperature influences the quality of formed coke products is avoided.
Description
Technical field
The utility model belongs to the charing field, is specifically related to a kind of dry coke quenching formula CARBONIZATION OF BRIQUETTES stove.
Background technology
Compare with the water quenching formula charring furnace in the conventional art, dry coke quenching formula CARBONIZATION OF BRIQUETTES stove and accessory has the advantage of practicing thrift cost and can not cause water to pollute.In the prior art; Chinese patent document CN201459016U discloses the continuous closed tunnel like CARBONIZATION OF BRIQUETTES of a kind of dry coke quenching stove; Comprise tunnel type furnace body and flue, the import and export of said body of heater is provided with the import and export fire door, on the intravital ground of said stove, is provided with track; Kiln car on the said track can be isolated the upper and lower in the stove, and said body of heater is provided with the dry coke quenching section at afterbody; Flue in this charring furnace comprises main flue, branch flue and the upper flue that communicates; Said main flue is arranged under the said body of heater face of land; Said branch flue is arranged in the two side of said upper of furnace body and with said track and parallels; Said upper flue is positioned at said body of heater top and parallels with said track, also has the air distribution outlet that is interlinked to the outside with stove on the said furnace body inside wall, and said air distribution outlet communicates with above-mentioned main flue, branch flue and upper flue.After charring furnace in this application is allocated air in certain amount into through air distribution outlet, in the stove internal combustion, cooperate branch flue and upper flue flue gas to circulate and fully burn, improve the coking speed of moulded coal greatly, the product coking is even, and quality is good.
But; The defective that above-mentioned prior art still exists is; In actual motion, because said upper flue is arranged on the top of said body of heater, said branch flue is arranged in the two side at said body of heater middle part; Therefore the flue gas in the said upper flue is more prone to discharge through main flue than branch flue, thereby causes the temperature in the branch flue will be higher than upper flue usually.Charing is very strict to the requirement of temperature, in carbonization process, if it is too high to be positioned at the branch flue temperature of said body of heater middle part inwall, can influence the quality of formed coke product.
Summary of the invention
Too high in order to solve the branch flue temperature that is positioned at said body of heater middle part inwall in the prior art, can influence the problem of formed coke quality product, the utility model provides a kind of dry coke quenching CARBONIZATION OF BRIQUETTES stove, can effectively regulate the flue-gas temperature in the branch flue.
The technical scheme of the described dry coke quenching CARBONIZATION OF BRIQUETTES of the utility model stove is:
A kind of dry coke quenching formula CARBONIZATION OF BRIQUETTES stove comprises:
