Abstract

The invention relates to the technical field of calcium carbide furnace gas, in particular to a filtering device for calcium carbide furnace gas treatment, and aims to solve the problems that a calcium carbide furnace gas treatment device in the prior art is inconvenient for cleaning dust on the surface of a filtering pipe and waste heat in flue gas cannot be recycled. According to the technical scheme, the filtering device comprises a filter tank, a water tank mounted on the outer wall of one side of the filter tank, a mounting box mounted at the top of the filter tank, and a plurality of ceramic fiber filter pipes mounted on the inner wall of the top of the filter tank, an air inlet is formed in one side of the filter tank, a dust discharge pipe is mounted at the bottom of the filter tank, and a dust discharge valve is mounted on the dust discharge pipe. An air outlet pipe is mounted in the mounting box, and the two ends of the air outlet pipe are each of a closed structure. The device is reasonable in structure and easy to operate, smoke dust attached to the ceramic fiber filter pipe can be conveniently removed, waste heat in furnace gas can be effectively utilized, excessive waste of energy is avoided, and the device is easy to popularize and use.

Description

technical field [0001] The invention relates to the field of calcium carbide furnace gas treatment, in particular to a filtering device for calcium carbide furnace gas treatment. Background technique [0002] In chemical industry, petroleum, metallurgy, electric power and other industries, high-temperature dusty gas is often produced. When using ordinary bag filter to filter out the dust in the furnace gas, it is necessary to cool down the furnace gas first, so that it will be easier to process. Therefore, in the prior art, ceramic fiber filter tubes are used to filter the calcium carbide furnace gas. However, due to the strong adsorption of ceramic fiber tubes, it is easy to cause the outer wall of the dust layer to be too thick and cause blockage. However, the existing calcium carbide furnace gas treatment The device lacks a mechanism for treating the dust on the surface of the ceramic fiber filter tube, and the heat in the high-temperature furnace gas has not been fully u...
