Coke oven smoke dust centralized collection system

Abstract

The invention relates to a coke oven smoke dust centralized collection system. The coke oven smoke dust centralized collection system is arranged in a fullytotally-closed cover body of a coke oven. The fullytotally-closed cover body completely seals the coke oven and accessory coke oven machinery. The coke oven smoke dust centralized collection system is installed on the top of the fullytotally-closed cover body and consists of a machine side coke pushing smoke dust collection pipe, a coke side coke outlet smoke dust collection pipe, an oven top coal loading smoke dust collection pipe and a smoke dust collection main pipe; and the smoke dust collection main pipe is connected with a dust removal floor ground station by virtue of a smoke dust conveying pipeline, and the smoke dust conveyingpipeline or the dust removal ground station are provided with a fan. By adopting the coke oven smoke dust centralized collection system, smoke dust of the fullytotally-closed coke oven such as the paroxysmal smoke dust in the operation of coal loading, coke pushing and coke discharging as well as the escaped smoke dust of various parts can be comprehensively collected, the overall structure is simple and reasonable, the operation is convenient, and the openness of an adjusting valve in each smoke dust collection pipe is controlled, so that the dust can be efficiently removed, and an energy-saving and consumption-reducing purpose can be achieved.

Description

technical field [0001] The invention relates to the technical field of coking oven coking, in particular to a coke oven smoke centralized collection system. Background technique [0002] In recent years, with the implementation of the new "Emission Standards of Air Pollutants for Coke Ovens", the requirements for environmental protection have become more and more stringent, and the requirements for the emission of pollutants such as smoke and waste gas have also been greatly increased. Pollutant emissions from coke ovens include coal dust, coke dust, and toxic gases, which have always been a key area of ​​supervision by the environmental protection department. Although an organized smoke dust and harmful gas emission system consisting of furnace top coal loading dust removal system, machine side coke pushing dust removal system, and coke side discharge dust removal system has been developed over the years, these three dust removal systems are independently configured and wor...

AI Technical Summary

Problems solved by technology

[0006] 1. The traditional coke oven is not equipped with a centralized coke oven dust collection system. The coke oven is in an open environment. The existing dust removal system can only collect the coke discharge dust and coal charging dust in an organized manner, and cannot discharge fugitively from the coke oven. Collect the fugitive smoke and dust, causing air pollution, unable to meet the new environmental protection requirements;

[0007] 2. Even if some coke ovens are provided with a dust collection device (such as "a kind of coke oven dust removal cover" disclosed by the Chinese patent application publication number CN107828430A), a semi-closed cover is only set on the top of the furnace, so only Collecting the smoke and dust escaping from the top of the coke oven cannot fully collect the smoke and dust escaping from the machine side and the coke side of the coke oven, nor can it meet the new environmental protection requirements

[0008] 3. The traditional coke oven is equipped with coal charging dust removal system on the top of the furnace, machine side coke push dust removal system, coke side discharge dust removal system and other organized collection and treatment systems for discharging smoke, dust and harmful gases, but the three dust removal systems are independently set up and work, takes up a lot of space, requires a lot of engineering investment, requires a lot of equipment maintenance, and reduces the cost performance of coke ovens
