Dehydrating and filtering device for processing acetylene

Abstract

The invention relates to the technical field of filtering devices, and discloses a dehydrating and filtering device for processing acetylene. The device comprises a mounting frame, wherein a filter cartridge is fixedly mounted on the mounting frame and comprises an air inlet, a connecting port, a filter cartridge body, a baffle plate, a partition plate, a filter tank I, a filter tank II, an air inlet pipe, a porous exhaust plate, an air outlet pipe, a liquid injection port, a liquid discharge port, a baffle plate and a liquid level meter; the air inlet is formed in one side of the filter cartridge body; the connecting port is formed in the other side of the filter cartridge body; the baffle plate is fixedly connected with the inner wall of the filter cartridge body; the interior of the filter cartridge body is divided into a first filter tank and a second filter tank through the partition plate; one end of the air inlet pipe is fixedly connected with the top of the partition plate, and the other end of the air inlet pipe is fixedly connected with the porous exhaust plate; the porous exhaust plate is arranged at the bottoms of the filter tank I and the filter tank II; and the air outlet pipe is arranged at the top of the partition plate. The dehydrating and filtering device solves the problem that a traditional acetylene gas filtering and drying device is poor in impurity removal effect.

Description

technical field [0001] The invention relates to the technical field of filtering devices, in particular to a dehydration filtering device for processing acetylene. Background technique [0002] Pure acetylene is a colorless, flammable gas with an aromatic odor. The acetylene made of calcium carbide is poisonous because it is mixed with hydrogen sulfide H2S, phosphine PH3, and arsine, and has a special odor. The explosion limit in air is 2.3%-72.3% (vol). There is a danger of violent explosion in liquid and solid state or in gaseous state and certain pressure. Factors such as heat, vibration and electric spark can cause explosion, so it cannot be stored or transported after pressurized liquefaction. Slightly soluble in water, soluble in ethanol, benzene, acetone. At 15°C and 1.5MPa, the solubility of acetylene in acetone is 237g / L, and the solution is stable. Therefore, in the industry, acetylene is pressed into a steel cylinder filled with porous substances such as asbes...

AI Technical Summary

Problems solved by technology

[0003] The produced acetylene gas contains a large amount of impurities, which needs to be filtered and removed before dehydration to obtain pure acetylene gas. Contains many other impurities, which cannot meet the requirements of use
