Abstract

A central gas-conducting fixed bed three-layer gas supply automatic-conversion tar gasifier is characterized in that a gasifying agent distributor is a three-layer heated gasifying agent distributor formed by intercommunicating a first heated gasifying agent distributor, a second heated gasifying agent distributor and a third heated gasifying agent distributor in a furnace body, distances among the three heated gasifying agent distributors are adjusted by the resistance, and pyrolysis gas and tar move towards a pyrolysis gas down channel to make tar pyrolyzed and gasified. The above structurewells solves the problem of tar generated in the gasification process of a coke oven, alleviates the problems of device corrosion, air pollution and difficult wastewater treatment caused by tar, greatly reduces the device cost, increases the gasification intensity, greatly improves the gasification performance, and provides a strong support for the development of the coal gasification technology.

Description

technical field [0001] The invention relates to a fixed-bed tar gasification furnace, in particular to a fixed-bed three-layer gas-supply self-reforming tar gasification furnace with a central gas guide. Background technique [0002] Coal gasification technology is the core and leading technology of the coal chemical industry, and one of the key technologies to realize the efficient and clean utilization of coal. The basis of process industries such as polygeneration systems, there are many types of coal gasification methods and equipment being applied and developed in the world at present, which can be divided into several typical methods such as fixed bed, fluidized bed and entrained bed according to their mixing mode and motion state Each gasification method has different requirements on the particle size, cohesiveness, reactivity, ash melting point, and operating conditions of the raw coal. At the same time, its thermal efficiency, carbon conversion rate, gasification in...
