Device for cleaning lid on coke-fired furnace

Abstract

The invention provides a cokery furnace cover clean-up device, which cleans a gas passage (7) and a knife edge support (4) at the two lateral sides and the bottom part of the furnace cover (1) through the high-pressure spray force, and cleans insulation material (5) through the mechanical cutting force. And compared with the two lateral sides and the bottom part, the top part of the furnace cover (1) is coated with less attachment like tar, carbon black, etc, the front parts of the gas passage (7) and the knife edge support (4) are cleaned only through the high-pressure spray force. The clean-up device is capable of cleaning the attachments adhered to the front parts of the gas passage (7) and the knife edge support (4), which are the most important functional parts of a furnace cover (1).

Description

technical field [0001] The invention relates to a furnace cover cleaning device on a coke furnace. Background technique [0002] In the coke oven type coke oven, the coal transported by the coal loading car is loaded into the furnace from the coal charging port provided on the furnace roof, and after the coal is dry-distilled to generate coke, the coal is fed through the openings formed at both ends of the furnace. Insert the ejector rod into the furnace on one side and push the coke in the furnace out from the opening on the other side. Although the opening is closed with the furnace cover during coal carbonization, tar and carbon black produced during coal carbonization adhere to the entire furnace cover, so if it is left intact, it will become a source of leakage of gas from the furnace cover and inhalation of the atmosphere. cause, and cause environmental pollution or ash the generated coke. [0003] The tar and carbon black attached to the furnace cover need to be rem...

AI Technical Summary

Problems solved by technology

[0005] (1) The steel plate 3 is very thin, and the steel plate 3 is easily damaged by the scraper method of mechanical contact

[0006] (2) The overlapping of the furnace cover 1 and the core of the furnace cover cleaning device has no margin in the front, rear, left, and right directions, so it is difficult for the scraper to be in close contact with the attachment cleaning surface of the steel plate 3

[0008] (4) When the attachment is tar, the texture is soft, and sometimes it cannot be completely removed only by the scraper

[0009] (5) The front end part of the blade-shaped support 4 is the most important place for the gas sealing of the opening, and the scraper method that may damage the blade-shaped support 4 cannot be used.

[0010] It is a major defect that the deposits on the gas channel 7 and the front end of the blade-shaped support 4, which are the most important parts of the furnace cover 1, cannot be removed well.

In other words, the conventional furnace roof cleaning device does not sufficiently remove furnace roof deposits, and it is difficult to say that it achieves the purpose of environmental protection or prevention of ashing of coke.
