Embodiment

[0057] Annual processing of shells and briquettes 40.32×10 4 t / a is an example, and the annual operating time is calculated as 8000 hours. The biomass gasification polygeneration charcoal thermoelectric process of the present invention is as follows.

[0058] (1) Biomass briquettes (wood chips, wood blocks) and fruit shells stored in the raw material warehouse are transported to the floor material warehouse 1, and then sent to the feeding belt conveyor 2 through the screw feeder in the floor material warehouse 1 . The feeding belt conveyor adopts a 52° corrugated edge belt, and the raw material is sent into the silo placed on the upper part of the gasifier 3 through the belt feeding device and the distributing device, and then opened by the slide valve at the lower part of the silo And closed to control the feeding, the raw material automatically falls into the biomass gasifier by its own gravity and the vibration of the vibration device at the lower part of the silo.

Abstract

The invention discloses a device and a technology for poly-generation of carbon, heat and electricity based on biomass gasification. The technology comprises steps of biomass transport, biomass gasification, boiler processing, electricity generation, desulphurization and dust removal. A large-dip-angle belt is adopted to perform continuous automatic feeding for biomass transport; a composite gasification fixed bed gasification technology with combination of upper and lower suction is adopted for biomass gasification, and a byproduct is a carbonized material; steam produced by a boiler after burning of gasified gas enters a steam turbine for generating electricity and then passes through a heat exchange station for providing a heat source for heating; a scattering tower based desulphurization and dust removal integration technology is adopted for desulphurization and dust removal. The device and the technology have the advantages of being environmentally friendly and safe and realizingpoly-generation of carbon, heat and electricity.

Description

technical field [0001] The invention belongs to the field of biomass gasification, and in particular relates to a biomass gasification polygeneration charcoal thermoelectric device and a process. Background technique [0002] As a renewable energy source, biomass plays an increasingly important role in the energy structure system. Due to the non-renewability of fossil fuels and coal and the impact on the environment during use, biomass energy will become one of the main energy sources in this century. . Biomass is abundant and widespread in our country. Vigorously developing biomass gasification technology is of great significance to alleviate the contradiction between energy supply and demand and reduce environmental pollution. The development of biomass energy conversion technology will be the key to this transformation. Contents of the invention [0003] The invention discloses a biomass gasification polycogeneration charcoal thermoelectric device and a process. The ...
