Novel high-purity acetylene purification production system and technological process thereof

Abstract

The invention discloses a novel high-purity acetylene purification production system and a technological process thereof, belonging to the technical field of acetylene production. The high-purity acetylene purification production system provided by the invention is high in purification degree and capable of saving cost. The system comprises a carbide slag settling pond, an acetylene generator, anacetylene gasometer, a safety water seal, a purifying tower, a purifying tower water tank, a neutralizing tower, a neutralizing tower water tank, a gas-water separator, a low-pressure dryer, a compressor, a high-pressure oil-water separator drying box and an acetylene filling system which are connected in sequence, wherein the height of a packing layer of the purification tower is 7-11m, the purification tower comprises a first purification tower and a second purification tower, and the second purification tower is connected with the neutralizing tower. The high-purity acetylene purification production system designed by the invention is high in acetylene purification purity which can reach 99% or above, and is reduced in the use cost of sodium hypochlorite.

Description

technical field [0001] The invention relates to the technical field of acetylene production, and in particular to a novel high-purity acetylene purification production system and its process flow, which are used for the purification production of high-purity acetylene. Background technique [0002] Acetylene, also called calcium carbide gas, is a colorless, slightly toxic and flammable gas with weak anesthesia and preventing cell oxidation at normal temperature and pressure. The explosion limit in air is 2.5% to 80%. Pure acetylene has no smell, but because the calcium sulfide and phosphide contained a small amount of calcium sulfide and phosphide in the calcium carbide raw material for the production of acetylene, solid industrial acetylene contains phosphine, hydrogen sulfide and other impurities and has an unpleasant garlic smell. It cannot be liquefied under normal pressure, hardly soluble in water, easily soluble in petroleum ether, ethanol, benzene and other organic s...

AI Technical Summary

Problems solved by technology

At present, the country has not issued a national standard for high-purity acetylene, but the quality requirements of the customer's receipt, the purity must reach more than 99%, and the silver nitrate test paper cannot change color

[0004] At present, the production process of dissolved acetylene mainly consists of four units of acetylene generation, purification and drying, compression and high-pressure drying, filling and calcium carbide storage. However, in the purification process, the purification purity cannot meet the requirements of customers, and the cost is high. Therefore according to above-mentioned problem, the present invention has designed a kind of novel high-purity acetylene purification production system
