Problems solved by technology

In the natural paragraph at the end of the second part, the article emphasizes that: "The technology of coking raw gas waste heat recovery and utilization technology has been researched in my country for nearly 30 years. Its materials and structures cannot meet the requirements of on-site working conditions, and its efficiency is low and its life is short. Breakthrough, so far there is no mature, reliable and stable large-scale industrial application example”

Embodiment Construction

[0015] Below in conjunction with the accompanying drawings, the present invention will be further described through embodiments

[0016] A waste heat utilization equipment for coke oven waste gas, comprising a riser 1, a double-layer casing 2 composed of an inner pipe 4 and an outer pipe 3, an inlet 5 and an outlet 6 of the double-layer casing on the riser shell, and a double-layer casing. A closed space is formed between the outer tube and the inner tube of the casing. The closed space is called interlayer. The double-layer casing enters the riser through the inlet through the riser shell. At the outlet, the inner tube of the double-layer casing is a flowing process medium, and the heat conduction medium is placed in the interlayer. The high-temperature waste gas in the coke oven rising tube transfers heat to the heat conduction medium through the outer tube, and the heat conduction medium transfers the heat to the process medium through the inner tube. .

Abstract

The invention relates to a waste heat recycling method and equipment of crude gas in a coke oven, and belongs to the technical field of waste heat utilization. The technical scheme is as follows: a closed space is formed between an outer pipe (3) and an inner pipe (4) of a double-layer sleeve (2) and is called as an interlayer; the double-layer sleeve penetrates through a shell of an ascending pipe from an inlet (5) and enters the ascending pipe; after internal distribution is finished, the ascending pipe (1) penetrates through the shell of the ascending pipe from an outlet (6); a flowing process medium is arranged in the inner pipe of the double-layer sleeve; heat-conducting medium is arranged in the interlayer; high-temperature crude gas in the ascending pipe of the coke oven transfers heat to the heat-conducting medium by the outer pipe; and the heat-conducting medium transfers the heat to the process medium by the inner pipe. The invention has the beneficial effects that a heat exchange surface does not have coke oil corrosion and bonding or floc blockage; and when the heat exchange surface is damaged, the process medium does not leak into a carbonization chamber of the coke oven. The invention has the advantages of obvious energy-saving effect, long-period and stable operation, safety, reliability and simple and convenient maintenance and repairing and the like, and solves the technical problem desired for being solved for long time in the field.

Description

technical field [0001] The invention relates to a waste heat utilization method and equipment of coke oven waste gas, and belongs to the technical field of waste heat recovery and utilization of coke oven waste gas. Background technique [0002] At present, people have accumulated abundant waste heat utilization technologies in the industrial field, and the utilization of waste heat from coke oven waste gas is also one of them. The waste heat has not been effectively utilized, and the heat can only be wasted by using circulating ammonia to cool down. Some people exchange heat with the waste gas and the process medium water in the jacket, but the problem of sticking tar and flocculation on the heat exchange surface occurs. After the heat exchange surface is damaged, the process medium water in the jacket leaks into the carbonization chamber and affects coke production. In recent years, the use of heat pipe technology and heat transfer oil technology for waste heat utilizatio...
