Coke oven capable of horizontally heating in reciprocating manner and vertically extracting coke

Abstract

A coke oven capable of horizontally heating in a reciprocating manner and vertically extracting coke comprises coking chambers, combustion chambers, and heat storage chambers arranged on the two sides of each of the combustion chambers, wherein an automatic oven door is arranged at the bottom of the coking chamber, a coke processing chamber internally provided with a conveyor is arranged below the coking chamber and the combustion chamber, a dry quenching furnace is arranged at the tail end of the conveyor, the combustion chamber is internally provided with a large number of horizontal flame paths separated by clapboard bricks, a lean gas / smoke port and an air / smoke port are respectively arranged at the two ends of each horizontal flame path, and each horizontal flame path in the combustion chamber is connected with the corresponding heat storage chamber. The coke oven heats quantitatively and is convenient to regulate when the gas is heated, the gas flow path is short, the gas is heated uniformly, the coke oven can automatically extract, convey and quench the coke in a closed environment at the lower part of the coke oven and utilizes the nitrogen gas to cool in a circulating manner and remove dust, therefore, the problems aiming at environmental protection and energy saving are solved fundamentally, meanwhile, oven doors on the two sides of the coke oven and a large-scale auxiliary coke oven machinery are cancelled, and the productivity is increased. As a result, the cost of the coke oven is lowered, and the operation cost is saved.

Description

technical field [0001] The invention relates to a horizontal reciprocating 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 ...

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
