Description

technical field [0001] The invention relates to a device and process for producing biomass gas, in particular to a device and process for producing biomass gas by self-fluidizing high-power continuous dry distillation. Background technique [0002] At present, with the increasing shortage of fossil energy, new energy production processes and devices that use biomass resources to replace petroleum liquefied gas and natural gas are also emerging. However, continuous and large-scale production has not been realized in the actual operation process. The calorific value of gas is low, the tar content is high, and the output cannot meet the needs of larger urban residents, which restricts the development of power generation and related industries. Therefore, a process is needed. And the device makes more reasonable use of biomass raw materials to produce biomass gas, maximizes equipment production capacity and product quality, and realizes substitution and emission reduction functi...

Problems solved by technology

[0003] The main purpose of the present invention is to solve the problem that the biomass raw material cannot move by itself during the production process of the device for producing gas by pyrolysis and cracking of biomass, which causes the phenomenon of smearing in the carbonization chamber and cannot realize continuous production;

[0004] The second object of the present invention is to solve the problem that the volume of the retort chamber in the biomass retort cracking device is small, so that the residence time of the biomass in the retort furnace is short, the effect of retort cracking cannot be achieved, and the problem that large-scale production cannot be realized;

[0006] The fourth purpose of the present invention is to solve the problem of using powdery raw material biomass to produce gas, resulting in low thermal efficiency in the carbonization furnace, resulting in incomplete cracking reactions of tar and charcoal, and the carbon powder produced still needs secondary processing. There are problems of high energy consumption, high cost and long process
