Abstract

The invention discloses a preparation device and method of biomass crucible coke. The device comprises a heating furnace, a reaction tube device, a protective gas supply device, a pressurizing device and a tail gas analyzing and processing device. The preparation method includes: preparing raw materials, loading the materials, pressurizing in a sealed manner, removing air, performing co-pyrolysis, forming the coke and the like. The preparation device and method has the advantages that by the preparation device and method, the high-quality biomass coke can be obtained, heat impact of protective gas on a crucible is reduced, tail gas component data can be used for the research of the biomass and coal mixed co-pyrolysis mechanism, the device is simple to mount, the method is simple, and environment pollution is avoided; in addition, the problem that the utilization approaches of the biomass which is used by the preparation device and method and is the only renewable clean carbon source are few is solved; another biomass utilization approach is provided to solve problems such as current high-quality coal resource shortage and environment pollution, and energy conservation and emission reduction of steel industry can be promoted.

Description

technical field [0001] The invention belongs to the field of co-pyrolysis coke production of biomass mixed with coal, and in particular relates to a preparation device and method of biomass crucible coke. Background technique [0002] Coal is an important coking raw material in my country. my country is rich in coal resources, with proven reserves of about 1.3 trillion tons, but coking coal resources, which are raw materials for coke production, are relatively scarce, accounting for only about 22% of the total coal resources. The position of coke in the steel industry is irreplaceable, and the amount of coke used in the steel industry in my country accounts for about 80% of the country's total output every year. At the same time, the utilization of coal resources is also accompanied by a large amount of CO 2 , SO 2 , NO X Environmental problems such as greenhouse effect and acid rain are becoming more and more serious. Facing the dual pressure of energy and the environm...
