Abstract

The invention discloses a kind of use fluffy biology raw material preparation coal gas craft and the equipment. The craft including the raw material pretreatment, the raw material gasification, is divided the principle to leave the dregs, the coal gas purifies, the coal gas transportation step; The equipment including the raw material pretreatment system, the coal gas has the system, the coal gas purification system, the coal gas transportation storing system. In this invention uses sets at the type fast fluidized gasification furnace and furnace accessories to have the production intensity in a big way, the gasified efficiency high, the gas tar content low, the operation stability is good and so on the characteristic. The gasification responded completes under the physical strength transfer rate, in sets at in the type separator realization gasification stove fresh material raw material fast circulation, the coal gas purification uses the method which the laundering and the organic solvent washes unifies, has tar removing rate to be high, in the coal gas the tar content change undulates slightly and so on the characteristic. The invention craft and the equipment may continuously gasify the fluffy fresh material raw material, gasifies the coal gas which produces to be possible to serve as the fuel gas generator the gas source, also may pass the pipe network to all around the side inhabitant user air feed.

Description

technical field

[0001] The invention relates to a process and equipment for preparing gas from biomass raw materials, in particular to a process for preparing gas from fluffy biomass raw materials, and also relates to a device for the process. Background technique

[0002] Biomass in a broad sense refers to hydrocarbons produced by photosynthesis. According to the texture of biomass raw materials, biomass raw materials can be divided into two types: dense type and fluffy type: dense type biomass raw materials mainly include forest logging residues, sorghum, corn, cotton and other crop straws, and fluffy type biomass raw materials It mainly includes agricultural straw such as rice straw, wheat straw, and rice husk. my country is a large agricultural country, and the crops are mainly wheat and rice, so the fluffy biomass raw materials account for a considerable proportion of my country's biomass resources.

[0003] How to efficiently and rationally develop and utilize fluffy...
