Furnace wall sectional supported dry quenching furnace with no airflow-free inclined channel structure

Abstract

The invention discloses a furnace wall sectional supported dry quenching furnace with no airflow-free inclined channel structure, the problems that the dry quenching furnace is easy to damage and theservice life is short can be effectively solved, the bottom of a straight barrel-shaped red coke pre-storage chamber wall body and the bottom of a red coke cooling chamber wall body are respectively supported and carried by a red coke pre-storage chamber rigid bearing ring and a red coke cooling chamber rigid bearing ring, the upper part of the red coke cooling chamber wall body, in a shrinking shape, is inserted into the red coke pre-storage chamber wall body, the upper part of a cooling air flow configuration chamber wall body is inserted into the red coke cooling chamber wall body, hot airflow collecting annular channels are arranged in the red coke pre-storage chamber wall body, hot airflow gathering channels are uniformly distributed at the bottom of the hot air collecting annular channels in the circumferential direction, one ends of the hot airflow gathering channels are communicated with the straight barrel-shaped red coke pre-storage chamber wall body, the other ends of the hot airflow gathering channels are communicated with the hot air flow collecting annular channels via an air flow adjusting outlet, a cooling air flow distribution ring channel and a cooling air flow jetting channel are arranged outside a conical barrel-shaped cooling air flow configuration chamber, and a cylindrical cold-coke outlet section outer wall body is connected with the cooling airflow configuration chamber wall body through a cooling airflow configuration chamber rigid bearing ring.

Description

technical field [0001] The invention relates to a coke oven, in particular to a dry quenching coke oven with a segmented furnace wall supporting a non-airflow chute structure used in an industrial kiln type coke dry quenching system. Background technique [0002] At present, the traditional hot coke water-cooled coke quenching (often abbreviated as wet coke quenching) in the coking industry has been basically replaced by inert airflow cooling coke quenching, usually referred to as dry coke quenching, which is an effective technical measure for energy saving and environmental protection in the coke quenching process. The key equipment in the CDQ system is the CDQ oven (chamber). The stability of its structure and the optimization of its performance are technical problems that need to be solved urgently. The working process in the CDQ oven is: the red coke (high temperature hot coke) coming out of the coke oven enters the CDQ oven from the top of the furnace, and the inert air...
