Horizontal pulverized coal fiber separator

Abstract

The invention discloses a horizontal pulverized coal fiber separator, and belongs to the field of coal gas chemical industry, the horizontal pulverized coal fiber separator comprises a shell arranged on a rack, a transmission shaft is arranged in the center of the shell from the front end to the rear end in a penetrating mode, and a driving assembly used for driving the transmission shaft is arranged at the front end of the shell; according to the carbon powder screening device, improvement is conducted on the prior art, carbon powder raw materials with fiber sundries rotate in the sweeping roller, the fiber sundries are continuously wound on the carding face, and carbon powder continuously moves towards the screen frame under the action of centrifugal force and is separated out from a discharging port below the screen frame; after the carbon powder is separated out, inert gas is blown to the screen drum through the screen cleaning mechanism, the fiber impurities can be sprayed to the fiber discharging opening, finally, the fiber impurities are screwed out under the action of the discharging valve, and the fiber impurities are prevented from blocking the fiber discharging opening.

Description

technical field [0001] The invention relates to the field of coal gas chemical industry, in particular to a horizontal coal powder fiber separator. Background technique [0002] In the coal gasification process, the raw coal is ground into fine powder by the coal mill, and then sent to the gasification furnace through the burner for gasification; since the raw coal needs to be ground during the process of mining, transportation, storage, etc., the pulverized coal is mixed with Fibers of different lengths, plastic bags, tiles, hemp silk and other messy debris will cause blockage of pneumatic conveying, pipelines, and gasifier bonding at the burner during high-temperature gasification, affecting the long-term stability of the system production run. In the prior art, the fiber debris in the coal powder is separated by a coal powder fiber separator. However, since this type of debris is very light, it cannot be directly dropped from the fiber separation port by gravity after se...

[0002] In the coal gasification process, the raw coal is ground into fine powder by the coal mill, and then sent to the gasification furnace through the burner for gasification; since the raw coal needs to be ground during the process of mining, transportation, storage, etc., the pulverized coal is mixed with Fibers of different lengths, plastic bags, tiles, hemp silk and other messy debris will cause blockage of pneumatic conveying, pipelines, and gasifier bonding at the burner during high-temperature gasification, affecting the long-term stability of the system production run

In the prior art, the fiber debris in the coal powder is separated by the coal powder fiber separator. However, since this type of debris is very light, it cannot be directly dropped from the fiber separation port by gravity after separation.
