Problems solved by technology

[0004] The purpose of the present invention is to solve the problem in the prior art that due to the fact that the circulation space of the furnace roof coal charging hole cannot meet the pressure requirements of the furnace roof during production, the emission of raw coal gas and smoke is not reduced from the structure of the furnace body, and the phenomenon of smoke and dust escape is serious. Shortcomings, and proposed a coke oven roof structure and coke oven body

Abstract

The invention discloses a coke oven top structure capable of realizing smokeless coaling. The coke oven top structure comprises a coke oven body and a collecting assembly. A plurality of fixing grooves A are formed in the top surface of the coke oven body, a plurality of fixing grooves C are formed in the top surface of the coke oven body, ascension pipes are fixedly mounted on the bottom surfaces of the fixing grooves C, a plurality of fixing grooves B are formed in the top surface of the coke oven body, a plurality of rails are arranged on the top surface of the coke oven body, and a carbonization chamber is arranged on the inner bottom surface of the coke oven body. The collecting assembly is arranged on the top surface of the rails and is used for collecting flue gas generated by coal charging and discharging raw gas in the coke oven body through the ascension pipe when coal charging is not carried out, so that the raw gas cannot be leaked, the pressure in the carbonization chamber is reduced, the pressure cannot be too high to cause fire, and an exhaust pipe is moved to the upper part of the ascension pipe; and in the production process, raw gas enters a collecting box through the exhaust pipe to be collected, so that the raw gas of the coke oven body does not overflow, and the raw gas is prevented from being directly discharged to pollute the environment.

Description

technical field [0001] The invention relates to the technical field of a coke oven body, in particular to a coke oven roof structure for realizing anthracite coal charging. Background technique [0002] During the coal charging process of the top-loading coke oven body, a large amount of raw gas overflows from the coal charging furnace mouth, which seriously pollutes the environment. In order to solve the environmental pollution caused during the coal loading process, it is generally solved by dust removal methods (vehicle dust removal, ground station dust removal), because raw gas has the characteristics of high temperature, flammability and contains a large amount of coal tar, with the improvement of environmental protection requirements and environmental protection The strengthening of law enforcement has become an urgent problem for coal coking enterprises to completely eradicate coal dust control. [0003] For example, the Chinese patent of CN212316012U proposes a coke...
