Description

TECHNICAL FIELD

[0001] The utility model relates to crude acetylene gas conveying device, especially crude acetylene gas conveying device's structure. BACKGROUND

[0002] In dry-process acetylene production, calcium carbide is fully reacted with water in acetylene generator to generate acetylene gas, calcium carbide slag dust is generated by the reaction of calcium carbide material and water, the generated acetyylene gas is high in temperature and contains a large amount of calcium carbide slag dust, which is called crude acetylene gas. In order to ensure the stable operation of subsequent equipment, it is necessary to use a washing tower to cool and remove dust from the crude acetylene gas, that is, the crude acetylene gas is introduced into the washing tower through a gas pipeline, the crude acetylene gas is removed by the spraying device in the washing tower, and the crude acetylene gas is cooled by the heat exchange device at the upper part of the washing tower to meet the quality requirements of the crude acetylene gas.

[0003] The calcium carbide slag in the crude acetylene gas is easy to absorb water and settle, and the calcium carbide slag carried by the crude acetyylene gas absorbs water and settles in the gas pipeline when passing through the gas pipeline, and continuously accumulates to block the gas pipeline.

The scraper is usually intermittently scraped, and calcium carbide slag accumulates in the gap between the scrapings and gradually solidifies, so that the scraper cannot be scraped out. More and more calcium carbide slag will eventually block the gas pipeline.
