Problems solved by technology

[0002] my country is a large agricultural country. According to statistics, 900 million tons of straw can be produced every year, but the effective utilization rate is less than 20%, and most of the rest are burned. This not only brings great pollution to the environment, but also wastes precious plants. resource

Embodiment Construction

[0010] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0011] figure 1 It is the flow chart of the concentrated gas supply process of straw pyrolysis gasification provided by the present invention:

[0012] First, the straw is cut into small pieces with a hay cutter, and the straw is sent into the pyrolysis furnace with a feeder. The straw is converted into combustible gas through pyrolysis and gasification reaction in the pyrolysis furnace, and the gas contained in the gas is removed in the purifier. Impurities such as dust and tar are sent to the gas storage cabinet by the blower. The gas storage cabinet provides a constant pressure to balance the fluctuation of the gas load to ensure the stable combustion...

Abstract

The invention provides a technological process and gasification equipment for central gas supply by biomass gasification. A lot of waste straws, dead wood and other plant resources in rural areas are fully utilized. The involved system consists of three parts: (1) a pre-treatment system, which includes a stockpiling warehouse, a hay cutter, and a feeding machine, etc.; (2) a gas production system, which includes a pyrolysis furnace, a cooler, and a Roots blower, etc.; and (3) a fuel gas distribution system, which includes tar purification plant gas storage cabinet and a gas transportation main pipe network, a tar purifier for users, a flow meter, a stove and the like. A gasification furnace adopts a dual-fluidized bed structure to separate combustion and gasification processes, the biomass raw material undergoes cracking reaction in the reactor, and by using a cracking purification technology, the tar generated in the gasification process can crack into an available disposable gas, so that the energy contained in the tar is well recycled, and the purifying rate is high. The technological process and the equipment provided by the invention improve the gasification efficiency, reduce the pipeline blockage, and avoid secondary pollution.

Description

technical field [0001] This patent proposes a process flow and gasification equipment for centralized gas supply using biomass gasification pyrolysis, and its products can be widely used in centralized gas supply for residential buildings, schools, institutions, troops, hotels, bathing centers, and nursing homes. Background technique [0002] my country is a large agricultural country. According to statistics, 900 million tons of straw can be produced every year, but the effective utilization rate is less than 20%, and most of the rest are burned. This not only brings great pollution to the environment, but also wastes precious plants. resource. Contents of the invention [0003] The purpose of the present invention is to make full use of plant resources such as straw and dead wood which are wasted in large quantities in rural areas by utilizing the biomass gasification technology. [0004] According to the purpose of the present invention, the present invention specifies ...
