Biomass recycling and recovering equipment

Abstract

Biomass recycling and recovering equipment is disclosed. The equipment comprises a biomass roller-way screening and cleaning machine, a cutter, a chain grinder, a high-concentration pulper, a material pulp pump, a water purifying system, a high-concentration dreg removing machine, a waste-heat exchanger, a material pulp high-pressure pump I, a supercritical hydrolysis liquefaction reactor, an intercooler, a material pulp high-pressure pump II, a subcritical hydrolysis liquefaction reactor, a distillation and rectification device, a storage tank I, a storage tank II, a storage tank III, a storage tank IV and an operation control center which are connected in order, wherein inlets and outlets of fluid mechanical material pipes are provided with electromagnetic valves. According to the equipment, a large amount of waste heat generated in a middle process can be fully utilized, conveying, screening and cleaning are finished in one conveying line in a raw material conveying and primary processing process, devices are reduced, previous preparation steps are reduced, the cost is saved, a final product is subjected to separation through a distillation and rectification process, requirements on modern industrial production can be met, and wider application of biomass energy can be achieved.

Description

technical field [0001] The invention relates to a biomass recycling recovery device, which is especially suitable for supersubcritical hydrolysis, liquefaction and refining of biomass such as crop stalks and wood flour, and belongs to the field of biomass chemical industry and energy in high-tech. Background technique [0002] Bioenergy is a kind of energy that stores solar energy in the form of chemical energy with organisms as the carrier, and it comes directly or indirectly from the photosynthesis of plants. Among various renewable energy sources, biomass is the stored solar energy and the only renewable carbon source that can be converted into conventional solid, liquid and gaseous fuels. It is estimated that the carbon fixed by plant photosynthesis on the earth reaches 2x1011t every year, and the energy content reaches 3x1021j. [0003] Biomass energy chemical industry is a production industry of oil, gas, electricity and other energy and chemical products produced by ...

AI Technical Summary

Problems solved by technology

In the existing data, equipment with the comprehensive advantages of supercritical hydrolysis technology and subcritical hydrolysis technology can be found to produce fermentable sugar. However, this kind of equipment is applied to small and medium-sized research users such as laboratories. Make full use of a large amount of waste heat generated in the intermediate process, and need to use a variety of equipment in the preliminary preparation work, occupying space, and wasting resources at the same time, and the end product is not separated by distillation and rectification, which cannot meet the needs of modern industrial production at all.
