Horizontal-type continuous biochar carbonization device

Abstract

The invention discloses a horizontal-type continuous biochar carbonization device, and belongs to the renewable energy technology field. The device comprises a feed hopper 1, a carbonization chamber 4, a high-temperature flue gas sleeve 6 and a gas combustor 18. The front end of the carbonization chamber 4 is connected with a feed spiral conveyer 2 through a feed inlet rotary feeder 3. The back end of the carbonization chamber 4 is connected with a char collecting box 15 through a char outlet pipe. The gas combustor 18 is connected with the high-temperature flue gas sleeve 6 through a combustion chamber. Raw materials are added into the carbonization chamber through the feed hopper; the diesel oil combustor is started; the temperature in the carbonization chamber rises; a pyrolysis reaction is generated; charred combustible gas is combusted, high-temperature flue gas is generated, and the carbonization chamber is heated for carbonization; the diesel oil combustor is shut down; the generated biochar is discharged through the char outlet pipe. The carbonization device solves the problems of difficult recycling of charred combustible gas and the like caused by discontinuous production during biomass char production processes, raises the quality and yield of biochar, and is suitable for different biomass raw materials. The carbonization device provides technical support for promotion of biochar industry development in our country.

Description

technical field [0001] The invention belongs to the technical field of renewable energy, and in particular relates to a horizontal continuous biochar carbonization equipment, in particular to equipment for producing biochar by means of thermal cracking, using crop straws as raw materials. Background technique [0002] Global warming has become one of the most far-reaching global environmental issues today. Various extreme climate events have occurred frequently in recent years, which have brought huge impacts on all fields of social development such as production, consumption, lifestyle and living space of human society. The sharp increase in the concentration of greenhouse gases in the atmosphere is mainly caused by the combustion of fossil fuels, changes in agriculture and land use, and industrial production processes. These fossil fuels produce a large amount of CO during the combustion process. 2 and other greenhouse gases. [0003] Convert agricultural residues such a...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of poor charcoal quality, low charcoal output rate, and difficult recovery and utilization of combustible gas in the process of biomass pyrolysis. A horizontal continuous biochar carbonization device is adopted to realize continuous production and improve charcoal Stability and quality; the use of combustible gas combustion to generate high-temperature flue gas to heat the carbonization chamber reduces the consumption of biomass raw materials in internal heat production and improves the charcoal yield. It is suitable for biochar production of different straw raw materials
