Method and device for delivering coke oven crude gas at high temperature

Abstract

The invention provides a method and device for delivering coke oven crude gas at high temperature. The device comprises a fire-resistant bottom partition layer, a combustor, a coke oven crude gas inlet pipe and a coke oven crude gas outlet pipe; a jacket layer is arranged on the upper portion of the fire-resistant bottom partition layer and sequentially comprises an inner cavity, a fire-resistantinner partition layer, a jacket cavity, a fire-resistant outer partition layer, a metal shell and an insulating layer from inside to outside; the combustor is used for enabling the inner cavity to meet preset high-temperature conditions; the coke oven crude gas inlet pipe is used for delivering the coke oven crude gas meeting preset input temperature conditions in a coke oven carbonization chamberinto the inner cavity; and the coke oven crude gas outlet pipe is used for delivering high-temperature coke oven crude gas to a non-catalytic reforming furnace. According to the method and device fordelivering the coke oven crude gas at the high temperature, the purpose of delivering the coke oven crude gas in a high temperature state is achieved for the first time, the phenomena that carbonaceous organic materials such as coal tar are separated out, and graphitization occurs in a delivering pipeline are avoided, and sensible heat of the coke oven crude gas and high-temperature water vapor resources are fully retained.

Description

technical field [0001] The application relates to the field of energy and chemical industry, in particular to a method for transporting raw coke oven gas at high temperature and a device for transporting raw coke oven gas at high temperature. Background technique [0002] Coke oven gas, a by-product of the coking industry, has become a large-tonnage energy and chemical resource. At present, the chemical utilization of coke oven gas is mostly concentrated in the production of methanol, synthetic ammonia, hydrogen, natural gas, etc. [0003] Coke oven gas is raw coke oven gas coming out of coke ovens. After initial cooling, a series of processes such as electric tar capture, ammonia removal, naphthalene removal, benzene washing, and desulfurization, etc., are cleaned after recovering tar, benzene, ammonia and other chemical products. Coke oven gas. [0004] Using clean coke oven gas as raw material to produce synthetic gas to synthesize chemical products such as methanol, di...
