Coke oven body structure for balancing pressure of carbonization chamber

Abstract

The invention relates to the technical field of coke ovens, and particularly relates to a coke oven body structure for balancing the pressure of a carbonization chamber. The coke oven body structure comprises a coke oven top, carbonization chambers and combustion chambers, wherein the combustion chambers and the carbonization chambers are regularly and adjacently arranged, the combustion chambers are arranged on the two sides of the carbonization chambers, the carbonization chambers are arranged on the two sides of the combustion chambers, each combustion chamber is composed of a plurality of parallel vertical flues, and the heating furnace walls of the combustion chambers are arranged on the two sides of the vertical flues; a pressure balance hole is formed in the furnace wall of the combustion chamber, the pressure balance hole is a through hole, the pressure balance hole is communicated with the adjacent carbonization chambers, the adjacent carbonization chambers are in a through state, and the combustion chamber and the carbonization chambers are in a separated state; and a maintenance and adjustment hole is formed in the top of the coke oven above the pressure balance hole. The coke oven body structure is especially suitable for tamping coke ovens, and can lead the raw gas generated by the carbonization chamber into the adjacent carbonization chamber to complete the export work of the raw gas without arranging a furnace top smoke guide machine, so that the smokeless coaling of the tamping coke ovens is realized.

Description

technical field [0001] The invention relates to the technical field of coke ovens, in particular to a coke oven body structure for balancing the pressure of a carbonization chamber. Background technique [0002] In the traditional tamping coke oven, when coal cakes are loaded into the carbonization chamber, part of the raw gas generated is collected from the top space of the carbonization chamber and then led to the gas collection pipe by the riser pipe, and the other part passes through the gas guide pipe on the flue gas conversion vehicle and The smoke guide holes on the top of the furnace lead to the adjacent (N+1, N-2 holes or other similar carbonization chambers), the carbonization chambers in the early or middle stages of coking (or the dust is discharged by the coke oven smoke guide car after combustion), In order to reduce the pressure of raw coal gas in the carbonization chamber of this hole (the Nth hole) at the initial stage of coal charging, and reduce the fugiti...

Problems solved by technology

[0003] The path of leading the raw coal gas to the adjacent carbonization chamber through the coke oven machinery on the top of the furnace is: raw coal gas generated in the carbonization chamber of this hole→rising to the top of the carbonization chamber→passing through the coke oven mechanical gas conduit→falling the raw gas→adjacent carbonization Chamber→Adjacent carbonization chamber The gas collection system leads to the gas collection pipe. This scheme has a long path, and the gas resistance is large during the rising and falling process. The gas is exported to the furnace body, and the temperature drops. Tar is easy to hang on the smoke guide pipe, which is difficult to maintain and easily affects normal production. , the overall effect is not ideal, and it is easy to cause pollution

Another method that is used in small quantities is the form of furnace top combustion type smoke guiding vehicle. The high temperature combustion of flue gas requires high coke oven mechanical equipment, high power consumption, high operating cost, incomplete treatment of pollutants, and waste of gas
