Description

TECHNICAL FIELD

[0002] As an important chemical raw material, acetylene has a wide range of applications in metal cutting, welding, chemical synthesis and other fields. However, acetylene gas often contains sulfides, phosphides and other impurities during production, which not only affects the purity and quality of acetylene, but also may cause safety hazards during use. Therefore, effective pickling of acetylene gas to remove impurities is a key step to ensure the safety and quality of acetylene gas application.

[0003] Referring to the announcement number CN220657509U, an acetylene gas pickling equipment, which includes a treatment box, the top of the treatment box is provided with a power box, the side of the treatment box is provided with an air inlet treatment box, the inside of the treatment box is provided with a partition, the lower part of the partition is an acid pickling cavity filled with pickling solution, and a floating sealing block that can float up and down is sleeved in the middle of the partition. When in use, the acetylene gas is preliminarily treated by the air inlet treatment box and then continuously injected into the acid pickling cavity. The acid pickling cavity is stirred by the driving of the power box, so that the acetylene gas and the pickling solution fully react. When the pressure inside the acid pickling cavity is not enough to make the floating sealing block float upwards, the acetylene gas can circulate and continuously clean inside the acid pickling cavity. When the pressure inside the acid pickling cavity can make the floating sealing block float, it can be discharged through the exhaust hole and collected and discharged through the gas collecting pipe. According to the above, although the pickling equipment can be better applied, it is usually not convenient to filter and cool the pickling acid solution, which makes it difficult to recycle the acid solution, resulting in high consumption of acid solution and general energy saving. Therefore, it needs to be improved. UTILITY MODEL CONTENTS
