Crude gas ignition method of coke oven diffusing tubes and device thereof

Abstract

The invention belongs to the technical field of coke oven crude gas treatment, in particular a crude gas ignition method of coke oven diffusing tubes and a device thereof. A steel tube is erected on the outer side of each diffusing tube of a coke oven in the same direction, the tops of the steel tubes are bent to the ports of the diffusing tubes, and the horizontal sections of the steel tubes are provided with one valve; an air inlet is arranged on the vertical section of the steel tube and is enclosed by an air door made of a steel board; the front end of the valve on the horizontal section of the steel tubes is filled with coke oven crude gas for heating the coke oven; the valves on the steel tubes are opened, the coke oven crude gas is ignited by a tinder at the air inlet, the burning flame rises to the tops of the steel tubes and spouts to the ports of the crude gas diffusing tubes; crude gas diffusing valves are opened, and then the crude gas is diffused to be ignited for burning. The invention greatly improves the safety of special operation of the crude gas diffusion of the coke oven, reduces the labor intensity, enhances the timeliness, greatly reduces the pollutant emission and has the advantages of simple operation, practicality, convenient maintenance and low investment cost.

Description

technical field [0001] The invention belongs to the technical field of coke oven waste gas treatment, and in particular relates to a method and device for igniting waste gas in a coke oven release pipe. Background technique [0002] In the production of coke ovens in coking plants, due to failures, planned maintenance and other reasons, the waste gas release pipe on the coke oven gas collection pipe needs to release a large amount of coke oven waste gas. Since the raw coal gas is directly discharged into the atmosphere, it will cause great environmental pollution. In order to reduce the corresponding pollution, it needs to be ignited and burned to burn most of the harmful substances in the raw coal gas as much as possible. The traditional method uses a 5m-high manual torch to ignite for diffuse ignition. Due to the special environment of the work site, the torch used is long and heavy. The operation is labor-intensive, extremely unsafe, and has poor timeliness. The use of a...

Problems solved by technology

The traditional method uses a 5m-high artificial torch to ignite the ignition. Due to the special environment of the work site, the torch used is long and heavy. The operation is labor-intensive, extremely unsafe, and time-sensitive

The automatic release ignition device is used, which requires a large investment. A release pipe costs more than 400,000 yuan, and the reliability of long-term use is poor, and the daily maintenance requirements are high.
