Problems solved by technology
[0002] The gas filtration system at the top of the traditional gas furnace is basically completed by an electric tar catcher and a scrubber. The electric tar catcher is mainly responsible for filtering the tar contained in the gas, and the scrubber is responsible for filtering the dust and particles in the gas. The top gas produced in the gas furnace is directly transported into the electric tar catcher, which will greatly increase the workload of the electric tar catcher and scrubber, and it is easy to cause the failure of the electric tar catcher and scrubber. At this time, it needs to be shut down for maintenance, which is serious affect normal production

The invention discloses a primary filter used for a coal gas purifying system, which is capable of reducing workload of an electrical tar precipitator and a washing tower. The primary filter comprises a filter main body, a middle baffle plate, an overflow port, filtration liquid and a filtered article discharge pipe, wherein the middle baffle plate is hoisted in the inner cavity of the filter main body, the upper part of the inner cavity of the filter main body is divided into a gas inlet chamber and a gas outlet chamber, the filtration liquid is filled in the lower part of the inner cavity of the filter main body, a gap allowing coal gas to pass is left between the liquid level of the filtration liquid and the middle baffle plate, the overflow port is formed above the liquid level of the filtration liquid, an overflow baffle is arranged beside the overflow port, a gas outlet port is formed on the gas outlet chamber, the inlet of the filtered article discharge pipe extends to the bottom of a water-seal body, the outlet of the filtered article discharge pipe extends out of the filter main body, a switching valve is arranged on the filtered article discharge pipe, and the highest point of the filtered article discharge pipe is lower than the liquid level of the filtration liquid.
Description
Technical field: [0001] The invention relates to a primary filter of a gas purification system. Background technique: [0002] The gas filtration system at the top of the traditional gas furnace is basically completed by an electric tar catcher and a scrubber. The electric tar catcher is mainly responsible for filtering the tar contained in the gas, and the scrubber is responsible for filtering the dust and particles in the gas. The top gas produced in the gas furnace is directly transported into the electric tar catcher, which will greatly increase the workload of the electric tar catcher and scrubber, and it is easy to cause the failure of the electric tar catcher and scrubber. At this time, it needs to be shut down for maintenance, which is serious affect normal production. Invention content: [0003] The purpose of the present invention is in order to overcome the above-mentioned shortcoming of prior art, provide a kind of primary filter that can reduce the working lo...
