Description

technical field

[0001] The invention relates to the technical field of dry ice blasting, more specifically, it relates to a tail gas treatment system of a solid-state CO2 scrubber. Background technique

[0002] Dry ice refers to solid carbon dioxide, which is widely used in various occasions. Among them, dry ice cleaning is used as a method of cleaning dirt, and it is often used as a cleaning treatment for optoelectronic devices. Existing dry ice blasting machines are usually equipped with dry ice manufacturing devices for direct use. In the process of dry ice manufacturing, gaseous carbon dioxide is generally sent to liquid carbon dioxide production devices through pipelines, and after cooling, compression, dehydrogenation, and purification , liquefaction and purification, etc., and then the liquid carbon dioxide is transported from the storage tank to the dry ice machine for manufacture, and in the process of producing dry ice by the dry ice machine, a part (about 60%) of ...
