Abstract

The invention discloses a tail gas treatment system of a solid CO2 cleaning machine, which relates to the technical field of dry ice cleaning. The cleaning device is equipped with a cleaning and sealing chamber, and the cleaning and sealing chamber is provided with a gas recovery pipe, which is connected to a filter device, and the filter device is connected to a gas delivery pipe. The tail gas device includes a circulating water pool, a carbon dioxide purifier and a carbon dioxide circulation pipe. The tail gas delivery pipe is coiled in the circulating pool, the gas delivery pipe is connected to the carbon dioxide purifier, and the carbon dioxide purifier is equipped with a carbon dioxide output pipe, the tail gas delivery pipe and the carbon dioxide output pipe are both connected to the carbon dioxide circulation pipe, and the carbon dioxide circulation pipe is connected to the dry ice manufacturing device . The invention can recycle and reuse the tail gas resource of the washing machine, reduce carbon dioxide emission, and has the advantages of improving its energy saving and environmental protection effect.

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 ...
