High-purity acetylene extraction device

Abstract

The invention relates to the technical field of acetylene extraction, and discloses a high-purity acetylene extraction device which comprises an extraction box, a heat insulation box is arranged in the extraction box, the right side, close to the upper end, of the heat insulation box communicates with the left end of an air inlet pipe, and the right end of the air inlet pipe penetrates through the inner wall of the right side of the extraction box and extends to the right side of the extraction box. The bottom of the heat insulation box communicates with the top end of an air outlet pipe, the bottom end of the air outlet pipe penetrates through the bottom of the inner wall of the extraction box and extends to a position below the extraction box, and the right end of the air inlet pipe communicates with the left end of a hose. According to the high-purity acetylene extraction device, a heat insulation effect can be achieved through the arranged heat insulation box, cold air can sequentially pass through a first communicating pipe and a U-shaped communicating pipe to enter a space formed between the heat insulation box and the extraction box by starting a fan, and then the cold air passes through the right end of the U-shaped communicating pipe and the interior of a second communicating pipe; and finally, the air flows out from an air outlet formed in the right side of a combined box to realize cold air circulation.

Description

technical field [0001] The invention relates to the technical field of acetylene extraction, in particular to a high-purity acetylene extraction device. Background technique [0002] Acetylene, commonly known as wind coal and calcium carbide gas, is the simplest alkyne compound. It is a colorless and highly flammable gas at room temperature. It is mainly used in lighting, welding, and rubber synthesis. Acetylene is slightly soluble in water, soluble in ethanol, acetone, etc. Its chemical properties are very active, and it can undergo reactions such as addition and oxidation. There is a danger of violent explosion in liquid and solid states or in gaseous states and under certain pressure. In industry, milky white steel cylinders are mostly used for storage and transportation. In the process of acetylene extraction, it cannot be in a heated state, which is prone to explosion, and in the process of acetylene extraction, the airflow velocity of acetylene cannot be controlled. T...

AI Technical Summary

Problems solved by technology

In the process of acetylene extraction, it cannot be in a heated state, and it is easy to explode under the heated state, and the air velocity of acetylene cannot be controlled in the process of acetylene extraction, so it is very necessary to propose a high-purity acetylene extraction device
