Technical Field
The utility model belongs to the technical field of the gravity dust removal technique and specifically relates to a gas purifier for biomass power generation.
Background
Common gas purifier all adopts gravity dust removal clarifier, and the theory of operation is that the gas flows through the clarifier, through the inside perpendicular baffle of clarifier's the effect of blockking, makes the gas velocity of flow reduce, and dust and tar in the gas subside under the action of gravity, fall into the ash bucket of below. The main reason for such design is that the gas is explosive gas and the moisture content is not too high, and electrostatic dust collection or water bath dust collection cannot be used, so the gravity dust collection purifier becomes the first choice. However, the traditional gravity dust removal purifier has the defects of large gas resistance, poor purification capability on tar and small-particle dust, and increased resistance of a gas conveying system due to the fact that the tar and the dust can be stuck on the cylinder wall after long-time use. On the other hand, dust and tar in the fuel gas fall into the dust hopper and also block the dust discharge pipe, so that dust cannot be discharged.

Wherein, in order to strengthen gas purifier dust removal and tar removal ability, install the wire net perpendicular with the flue gas flow direction in the clarifier barrel. Can be when the gas clarifier of flowing through, dust and tar in the gas collide with the wire net, further reduce the velocity of flow, make it more easily on the clarifier section of thick bamboo wall of entrapment, strengthen the purifying power of clarifier.
Meanwhile, in order to prevent tar and dust from being adhered to the cylinder wall and the ash bucket after being mixed, 5 hot air purging pipes are arranged on the circumference of the top of the gas purifier to perform hot air purging on the purifier to remove the dust and the tar adhered to the cylinder wall, and the hot air purging pipes can also be used for cleaning the dust and the tar in the collecting box to prevent the ash discharge pipe from being blocked.
A gas purifier for biomass power generation comprises a cylinder body, wherein the upper part of the cylinder body is cylindrical, the lower part of the cylinder body is conical, a filter screen is arranged in the cylindrical part of the cylinder body, the section of the filter screen is annular, the center of the annular is provided with an inner cylinder wall, the circumferential surface of the cylinder body is provided with a gas inlet pipe, the central axis of the gas inlet pipe is tangent to the outer circumferential surface of the cylinder wall of the cylinder body, the cylinder body is provided with a sealing end cover, five groups of gas outlet pipes and a hot air purging pipe are arranged on the sealing end cover at equal angles, the gas inlet of each gas outlet pipe is aligned to a middle; an electromagnetic valve is arranged at the air inlet of the hot air purging pipe.
The lower part of the cylinder body is provided with a collecting box, and an electric ash valve is arranged below the collecting box.
The gas inlet pipe is connected with the gas outlet of the booster fan, the gas inlet of the booster fan is connected with the biomass gasification furnace, the gas outlet pipe is connected with the gas inlet of the Stirling generator, and the hot air purging pipe is connected with the air preheater of the Stirling generator.
The utility model discloses a gas purifier for biomass power generation, prior art compares produced beneficial effect and is:
1) compared with the traditional gravity dust removal purifier, the gas purifier designed by the invention has better dust removal and tar removal effects because the steel wire mesh is arranged in the barrel aiming at the gas generated by the biomass gasification furnace.
2) The hot air blowing system can effectively remove dust and tar on the wall of the purifier cylinder, so that the resistance of the gas purifier is smaller, and the service life of the gas purifier is long.
3) Two gas purifier systems are arranged, one is used and the other is prepared, the operation process of the unit is switched at will, online cleaning can be realized under the condition of not stopping the furnace, and the whole system can stably operate for a long time.
