Electric tar precipitator for clean gas production

Abstract

The invention relates to the technical field of gas production equipment, and discloses an electric tar precipitator for clean gas production. The precipitator comprises a precipitator body, and a gas inlet is fixedly mounted at the bottom of one side of the precipitator body. According to the electric tar precipitator for clean gas production, through the conical structure of the precipitation pole, the precipitation pole below is farther from a corona pole, the electric field intensity is smaller than that above the precipitation pole, the adsorption capacity on tar in a gas is small, the gas flows to the upper portion from the lower portion, the tar is uniformly adsorbed on the upper portion and the lower portion of the precipitation pole, and the bottom of the precipitation pole cannot be blocked within a short time. The bottom of the precipitation pole in the equipment cannot be quickly blocked firstly, tar is fully adsorbed by the upper part and the lower part in the precipitation pole, the working utilization rate of the precipitation pole is high, meanwhile, after the accumulation gravity is increased, the tar can be separated and fall under the action of gravity and cannot be accumulated at the bottom of the precipitation pole, and a problem that a local voltage is increased caused by tar accumulation so that breakdown fracture of a corona electrode is generated is prevented; and therefore, the service life of the corona electrode is ensured.

Description

technical field [0001] The invention relates to the technical field of gas production equipment, in particular to an electric tar catcher for clean gas production. Background technique [0002] The aggravation of the energy crisis worldwide and the implementation of mandatory environmental protection policies around the world have made countries eager to seek a cheap and clean energy to replace oil and natural gas. The clean use of coal, especially the research on coal gasification, has been put on the agenda Come up, after the coal is gasified in the gas generator, the discharged gas contains tar, which requires an electric tar collector to capture and purify the tar in the gas. [0003] The electric tar catcher uses positive ions to adsorb on the negatively charged corona electrode, and negative ions to adsorb on the positively charged precipitation electrode. All ionized positive and negative ions fill the entire space between the corona electrode and the precipitation el...

AI Technical Summary

Problems solved by technology

[0005] The invention provides an electric tar catcher for clean gas production, which has the advantages that the electrode parts are not easy to be broken down, the corona is not easy to be damaged, the upper and lower sides of the sedimentation pole absorb tar evenly, and the bottom is not easy to be blocked, which solves the problem of adsorption and accumulation under the sedimentation pole , the gas that continues to rise to the top contains less tar, the bottom method accumulates seriously, it is easy to block, and the corona pole shakes and easily breaks down the air corona pole damage problem
