Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] It is worth noting that the orientation words such as "up" and "down" involved in this article are all determined relative to the perspective of the drawings, and are only for the convenience of description, and cannot be understood as limitations on the technical solution.

[0025] see figure 1 and figure 2 , a method for repairing the damaged point of the coke oven bridge tube wall, selecting the damaged point of the coke oven bridge tube wall at the end of coking in the carbonization chamber to repair; the specific repair process includes:

[0026] S1: first close the valve body 9, so that the gas collecting pipe 10 can no longer communicate with the bridge pipe 3, and avoid high-temperature gas in the bridge pipe 3;

[0027] S2: Then remove the tar and graphite in the bridge tube 3;

[0028] S3: When starting the repair, select two meta...

Abstract

The invention relates to a coke oven bridge pipe wall damage point repairing method which comprises the steps that two metal plates matched with a damage point in size are selected, cold welding rodsare smeared on the faces, corresponding to the coke oven bridge pipe wall damage point, of the metal plates, and the thickness of the cold welding rods is 1 mm; and the metal plates are attached to the inner wall and the outer wall of the damage point respectively and kept for more than one minute. Good sealing and air tightness are guaranteed, and smoke and fire are thoroughly eliminated. The safety risk is eliminated, the labor intensity of staff is reduced, and meanwhile the spare part cost of the bridge pipe is reduced.

Description

technical field [0001] The invention relates to the technical field of coke oven repair equipment, more specifically, it relates to a method and device for repairing damaged points on the tube wall of a coke oven bridge. Background technique [0002] The temperature of the raw gas from the carbonization chamber exceeds 700°C when it passes through the bridge tube, and a large amount of circulating ammonia water is used to spray and cool the bridge tube, so that the raw gas is rapidly cooled to 80-90°C, and the temperature drops suddenly, resulting in uneven stress and Deformation and cracking, forming damage points. At present, coking plants generally adopt the method of replacing the bridge tube with a new bridge tube to eliminate smoke and fire. This method takes a long time to process, has high safety risks, and the cost of spare parts is also high. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is ...
