Abstract

The invention discloses a biomass pyrolysis fuel gas electrical tar precipitator with high purification rate, which comprises a barrel, a gas inlet located in the lower portion of the barrel, an exhaust port located in the upper portion of the barrel. A precipitation electrode of a tubular structure is arranged at the position, between the gas inlet and the exhaust port, of the inner side of the barrel, an inner channel of the precipitation electrode is communicated with the gas inlet and the exhaust port, and an electrode wire is further arranged in the precipitation electrode. A plurality of inverted conical annular parts are coaxially arranged on the inner wall of the precipitation electrode, the inverted conical annular parts are uniformly distributed along the length extension direction of the precipitation electrode, and a gas channel is reserved between the middle part of each inverted conical annular part and the electrode wire; the electrode wire is provided with a bur part for corona onset; and the barb part is positioned between the upper and lower inverted conical annular parts. The invention aims to improve the capture performance by optimizing the structure.

Description

technical field [0001] The invention relates to the technical field of biomass fuel production, in particular to an electric tar catcher for biomass pyrolysis gas with high purification rate. Background technique [0002] Combustible biomass pyrolysis gas can be produced through a certain pyrolysis process of biomass such as rice husks and orange stalks. The combustible gas contains a large amount of dust, particles, water vapor, tar and other substances. [0003] In related technologies, equipment such as spray towers and swirl towers are used to remove tar, etc., and electric tar catchers are also used, which is a method of using dust tar and other impurities in high-voltage electric field gas to charge and separate them under the action of an electric field to collect dust. , tar and other impurities of industrial equipment. Its working principle is that the negative high voltage generated by the high-voltage DC power supply is connected to the corona electrode through t...
