The invention discloses an interstage cooling and separating integrated device for a vapor
compression system, and belongs to the technical field of cooling and separating. The device comprises a shell, an atomization
system, a modular demisting unit and a silk screen self-cleaning unit, a partition plate is arranged in the shell and divides the shell into an upper cavity and a lower cavity, an isolation silk screen is arranged on the partition plate, and the atomization
system comprises an atomization
nozzle; the device further comprises a separation cavity, the separation cavity is arranged at an inlet of the air outlet
pipe through flexible connection, and the modular demisting unit comprises a separation silk screen; the silk screen self-cleaning unit comprises a sliding cavity, a sliding block and a thin plate, the thin plate can move upwards when blown by
airflow, the sliding block can be driven to move up and down in the sliding cavity to generate vibration, and liquid drops on the separation silk screen are separated. According to the invention, the functions of interstage cooling and gas-liquid separation are integrated, the number and occupied area of equipment are reduced, the separation silk screen can vibrate along with the separation cavity, liquid drops gathered on the separation silk screen are separated from the separation silk screen due to vibration, the cleaning capability is excellent, and the service life of the silk screen can be prolonged.
