Small biomass gasification purification device

Abstract

The invention relates to a small biomass gasification purification device which comprises a reaction bin (1), a purifier (3), a pipeline for connecting the reaction bin (1) and the purifier (3), and abooster fan (2) arranged on the pipeline, wherein the purifier comprises a separation cavity (6), a cooling cavity (5) and a filtering cavity (4) which are sequentially arranged from bottom to top; apurifier air inlet (304) is formed in the separation cavity; and a purifier air outlet (301) is formed in the filtering cavity. The reaction bin is compact in structure under the condition that gas cooling and conveying functions can be achieved. The gasification purification device is compact in structure and small in size, can purify gas in three different modes which are high-speed collision liquefaction separation, cooling liquefaction separation and filtering separation in sequence, purification is thorough and a product is high in purity. In addition, the device is simple to operate andparticularly suitable for individuals or rural users. In addition, separation and recycling of tar and pyroligneous acid are achieved, and the gasification efficiency and the raw material utilizationrate are improved.

Description

technical field [0001] The invention relates to the field of biomass energy utilization, in particular to a small biomass gasification and purification device. Background technique [0002] With the development of the economy and society, the improvement of the quality of life in rural areas and the change of lifestyle have brought huge energy and environmental pressure: now the rural areas have basically achieved full access to water and electricity, and the heating for cooking and drinking has basically changed from the previous burning of straw and branches to Coal is burned, but non-renewable resources such as coal are increasingly scarce, and the treatment of straw and branches in rural areas is usually done by field burning, which not only causes great pollution to the environment, but also poses a great safety hazard. [0003] In view of this severe problem highlighted in rural areas, considering that rural branches, straw, straw and livestock manure are all important...
