Embodiment 1

[0047] A biomass continuous decomposition process, comprising the steps of:

[0048] (1) The biomass raw material is sent to the air drying device for drying, and the dried biomass raw material is pushed into the carbonization furnace by the propulsion device, and the biomass raw material is compressed during the propelling process; this step also includes the biomass raw material ( Biomass raw materials refer to the steps of sorting and feeding the plant straws, and transferring the biomass raw materials to the air-drying device after sorting; the purpose of compressing the biomass raw materials (that is, straw bales) during the advancing process is to discharge the air inside. Increases the rate of decomposition into char (prevents incineration).

[0049] (2) Decompose the compressed biomass raw material in a carbonization furnace. When the biomass raw material reaches the decomposition temperature:

[0050] a. Open the gas collection valve to collect the gas produced by th...

Abstract

The invention discloses a biomass continuous decomposition process and device. The biomass continuous decomposition process comprises the following steps: compressing a dried biomass raw material in the push process; igniting and decomposing the compressed biomass raw material in a carbonization furnace, filtering a gas collected after decomposition, cooling, decoking, and compressing into a storage tank for later use; feeding the biomass carbon into a cooling device, introducing cold air into the cooling device for heat exchange, and introducing hot air after heat exchange into a drying device in step (1) to dry the biomass raw material. By adopting the biomass continuous decomposition process, a combustible gas, tar and carbon powder generated when biomass is continuously decomposed can be effectively separated and utilized, the heat generated from biomass decomposition can be effectively recycled, the energy can be saved, and the environment can be protected.

Description

technical field [0001] The invention relates to the technical field of biomass carbonization, in particular to a biomass continuous decomposition process and device. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Now a large amount of straw is produced in agricultural production. Traditional straw is mainly disposed of by incineration, which pollutes the air and fails to obtain effective benefits. Straw carbonization is an effective application, and it is being vigorously promoted at present. Straw carbonization is to dry or sun-dry and crush the straw, and then in the charcoal equipment, through drying, dry distillation, cooling and other processes, the loose straw is The process of making charcoal. During the straw carbonization process, the straw bales are transported to the conveying device through the feeding device, and then sent to the air-drying device through the conveying device. the goal of. However, the...
