Abstract

The invention relates to a novel straw direct gasification polygeneration preparation process, comprising a gasification furnace, a feeding device, a material pushing device, a material pressing device, a material homogenizing device, a carbon discharging device, a washing device, a fan, a water seal filtering device, a gas holder and a control cabinet. By virtue of the feeding device, the material pushing device, a material pressing device and a material homogenizing device, straw requiring no processing is directly fed into a gasification furnace to be gasified, the straw is effectively controlled to polygenerate straw carbon and straw gas, a carbon scraping grate and the carbon discharging device are combined to collect the straw carbon, labyrinth type spraying washing is carried out to separate the straw gas and straw extract, the water seal filtering device filters and collects the straw gas, and the device has high reliability, good safety performance, strong practicability, simple gasification process, good gasification effect, high straw utilization rate and low operation cost.

Description

technical field [0001] The invention relates to a straw direct gasification process, in particular to a preparation process for direct utilization of new gasification polygeneration straw gas, straw charcoal and straw extract without cutting or crushing of straw. Background technique [0002] In recent years, there are many technical methods for the regeneration and recycling of crop straws at home and abroad, such as direct combustion, gasification, liquefaction, compression molding, biochemical transformation or the manufacture of artificial boards, etc., but due to various reasons or conditions, the investment is less, There are not many methods with mature technology, economical feasibility, and convenient application. In addition, my country has a vast territory, great differences in natural conditions, and many types of straw resources, which are affected by factors such as poor conversion channels, low conversion rates, and poor economic benefits of crop straws. Althoug...
