AI Technical Summary
During gas sampling in medium- and high-temperature geothermal fields, the high-temperature gas causes a sharp rise in the temperature of the sampling equipment, affecting the equipment's working efficiency, especially the normal operation of electrical equipment. Furthermore, the high-temperature gas contains particulate impurities such as dust, which affects subsequent observation and research.
Rapid cooling is achieved by using a first and second ring pipe filled with cryogenic liquid nitrogen gas. Combined with a filtration mechanism and cleaning components, the gas is guided to cool down by dividing the area through an annular baffle, and impurities are cleaned by a filter plate and scraper assembly to prevent impurity accumulation.
It enables rapid cooling of gases from medium- and high-temperature geothermal fields, preventing a decrease in equipment efficiency, and effectively filters and cleans dust and impurities in the gases, ensuring stable operation of the sampling device and data accuracy.
