Background
In the dry acetylene production, calcium carbide fully reacts with water in an acetylene generator to generate acetylene gas, and the generated acetylene gas has high temperature and carries a large amount of calcium carbide slag dust and water vapor, which is called crude acetylene gas for short. The crude acetylene gas enters the washing tower through the gas phase channel for washing and cooling so as to meet the quality requirement of the acetylene gas.
In the prior art, a gas phase scraper is arranged in a gas phase channel, the gas phase scraper is a circular scraper and is connected with an external air cylinder through a pull rod, and nitrogen is introduced into the air cylinder to provide power for the scraper to move back and forth. Because of the easy moisture absorption of carbide slag in the crude acetylene gas subsides, continuous reaction in the acetylene generator continues to carry crude acetylene gas to the scrubbing tower, and when passing through the gas phase passageway, the carbide slag that carries in the crude acetylene gas subsides to the gas phase passageway in after absorbing water, piles up in succession and makes the gas phase passageway block up. When the gas-phase scraper dredges the carbide slag accumulated in the gas-phase channel, the action of the gas-phase scraper is 15S intermittent action, and the gas-phase scraper cannot completely dredge the accumulated carbide slag because the power provided by the nitrogen is small, so that the gas-phase channel is finally blocked by the accumulated carbide slag. In order to prevent the generator from being stopped under pressure, the generator needs to be stopped continuously to clean the gas-phase channel, continuous production cannot be realized, and the cleaning of the gas-phase channel not only has long replacement time of the generator process, but also has influence on the whole production line.
