Transverse alternative heating and vertical coke exhaust coke oven

Abstract

The invention discloses a transverse alternative heating and vertical coke exhaust coke oven which comprises a carbonization chamber, combustion chambers and heat storage chambers which are respectively arranged on two sides of each combustion chamber, wherein an automatic furnace door is arranged at the bottom of the carbonization chamber; a coke treatment chamber in which a conveyor is arranged is arranged below the carbonization chamber and the combustion chambers; a dry quenching furnace is arranged at the tail end of the conveyor; each combustion chamber is divided into a left cavity and a right cavity; multiple double-linkage horizontal flame paths are respectively formed above and below the cavity on each side, wherein the double-linkage horizontal flame paths comprise two adjacent up-down horizontal flame paths between which clapboard bricks are arranged, crossing holes and circulating holes are reserved in the clapboard bricks, and lean gas / flue gas openings and air / flue gas openings are formed in external walls of the flame paths; and each double-linkage horizontal flame path of the combustion chamber is respectively connected with a corresponding heat storage chamber. The coke is automatically exhausted, conveyed and quenched in a closed environment on the lower part of the coke oven, and the problems of environment friendliness and energy conservation are fundamentally solved by utilizing nitrogen circulating cooling and dust removal. Meanwhile, the furnace doors on two sides of the coke oven can be canceled, and large mechanical equipment attached to the coke oven is canceled. Moreover, the investment of the coke oven is reduced, and the operating cost is saved.

Description

technical field [0001] The invention relates to a horizontal alternate heating and vertical coking discharge type coking oven, which belongs to the conventional coking technical field in the coking industry of the metallurgical industry. Background technique [0002] Existing large-scale conventional mechanical coke ovens are all composed of a coal material carbonization system and a gas heating system. In the upper part of the furnace body, dozens of carbonization chambers and dozens of combustion chambers are distributed alternately. In the combustion chamber, the heating gas is burned, and the heat is transferred to the carbonization chamber through the furnace wall. In the carbonization chamber, the coal material is heated and carbonized; in the furnace body In the middle, dozens of regenerators are distributed, which are used to alternately recover the waste heat of flue gas and preheat the heating gas; Flue, branch flue, exhaust gas tray, etc., are used to supply and ...

AI Technical Summary

Problems solved by technology

It can be seen that the upper, middle, and lower parts of the existing coke oven—the gas heating area, the heat storage area, the heating gas and flue gas entry and exit, and the adjustment area not only form a complicated relationship between upper and lower connections, horizontal shunts and confluence adjustments; more importantly, they hinder The material system uses natural gravity to discharge coke

Therefore, the structure of the furnace body is unreasonable, the heating system is complicated, the operation is difficult, and the resistance is large.

[0005] Since the beginning of this century, in order to improve production capacity and labor productivity, the existing coke ovens have been blindly developing towards the high-orientation, wide-orientation, and maximum length of the carbonization chamber. If it is not large-scale, the supporting ground dust removal device and CDQ facilities have to be large-scale. In turn, the processing capacity of the coke oven machinery limits the number, height and length of the coke oven carbonization chamber, and the coke pusher rod of the coke pusher Caused damage to the furnace wall of the carbonization chamber, reduced the service life of the coke oven, failed to effectively release the production capacity of the coke oven, and did not fundamentally solve the coke discharge pollution and energy loss of the coke oven
