Carbon dioxide snowflake nodule cleaning device

By installing a liquid inlet component in the carbon dioxide snowflake nodule cleaning device, the liquid carbon dioxide forms snowflake nodules in the liquid phase change channel and mixes with compressed gas, accelerating the spraying out. This solves the problem of nozzle frosting and improves the reliability and stability of the device.

AI Technical Summary

Technical Problem

In existing carbon dioxide snow cleaning devices, snowflake particles that do not come into contact with compressed gas frost up at the nozzle, causing nozzle blockage and affecting operational reliability and stability.

Method used

A carbon dioxide snowflake nodule cleaning device is designed. By setting a liquid inlet component in the device body, the liquid carbon dioxide undergoes a phase change in the liquid phase change channel to form snowflake nodules, which are then mixed with compressed gas to ensure that it is accelerated before being sprayed out, thus avoiding frost at the outlet channel.

Benefits of technology

This improves the reliability and stability of the carbon dioxide snowflake nodule cleaning device, ensuring cleaning effectiveness while reducing the risk of nozzle clogging.

Abstract

This utility model belongs to the field of carbon dioxide cleaning technology and discloses a carbon dioxide snowflake nodule cleaning device. It is used for cleaning areas and includes a device body and a liquid inlet assembly. The device body extends through the entire surface and has an internal cavity. One end is a liquid carbon dioxide inlet channel, and the other end is an outlet channel. Compressed gas is introduced through an opening in the side wall. One end of the liquid inlet assembly is sealed to the inner wall of the cavity, and a through liquid phase change channel connects to the inlet channel. The other end of the liquid inlet assembly extends within the cavity, and its outer wall and the inner wall of the cavity enclose a mixing zone. The outlet channel, the other end of the liquid phase change channel, and the mixing zone are interconnected. The carbon dioxide snowflake nodule cleaning device provided by this utility model helps to simultaneously accelerate the compressed gas and carbon dioxide snowflake nodules before ejection, avoiding condensation at the outlet channel and improving the reliability and stability of the device.
