Method for simultaneously preparing charcoal, gas and liquid products from crop straw and application thereof

Abstract

The invention relates to a process for simultaneously preparing charcoal, gas, and liquid products with crop stalks and the application thereof. The process is that the crop stalks (rice husk, nut shell, branches of fruit trees, wooden and bamboo waste materials, and the like) are conveyed to a gasification furnace, the gasification furnace is provided with oxygen by the employment of controlling the height of the a batch layer and the air quantity of an air extractor, and the air achieved via gas-liquid separation is conveyed into a gas turbine for generating or directly supplied to users, vinegar fluid is achieved by condensing and reclaiming the liquid, the vinegar fluid can be processed to be antiseptic solution and deodorizer which are used in livestock places, and also can be processed to be pesticide agent or pesticide which can resist insect and disease, further can be used for foliage fertilizer which can promote the growth of crops and has perfect effect in the production of organic vegetable, fruits and agronomic crops. Straw charcoal achieved from imperfect burnt straws is rich in essential nutrients for the growth of crops, which has a long term slow releasing action for water and fertilizer, has improvement and renovation effect for the soil which is polluted and degenerated by heavy metal, and can be processed to be organic compound fertilizer or insulating material of iron and steel industry and the like.

Description

technical field [0001] The patent of the present invention relates to a method and application for simultaneously producing charcoal, gas and liquid products from crop straws (various straws, rice husks, fruit shells, fruit tree branches, wood and bamboo waste materials, etc.). Background technique [0002] At present, known pyrolysis utilization technologies such as crop straws include gasification to produce combustible gas for power generation or gas supply, dry distillation pyrolysis, or earth kiln to directly pyrolyze crop straws into charcoal. These methods only use gas or charcoal for the utilization of crop stalks, etc., and the economic benefits are not good, and they need to rely on economic or policy subsidies from the state and local governments to maintain their operation. Contents of the invention [0003] The purpose of the present invention is to comprehensively and efficiently utilize crop stalks, rice husks, fruit shells, fruit tree branches, wood and bam...
