[0059] The first air inlet 120 is connected with the spraying room through a pipeline and a pump machine. The impure gas in the spraying room is extracted to the inner cavity of the first air inlet 120 through the pipeline and the pump machine. The impure gas enters the inner cavity of the cylinder 110 through the first air inlet 120 and is separated in the inner cavity of the cylinder 110;

[0060] The spiral mechanism 200 is installed in the inner cavity of the first air inlet 120. The impure gas is spirally guided through the first air inlet 120. The impure gas spirally advances in the inner cavity of the first air inlet 120. The impure gas rotates in the inner cavity of the first air inlet 120;

[0061] The rotation of the impure gas generates centrifugal force. The particles in the airflow are thrown to the wall under the action of the centrifugal force, achieving the purpose of pre-separation.

[0062] The rotation of the airflow also enhances the turbulence intensity. The turbulence can increase the relative motion speed between the gas and the particles. The enhanced turbulence intensity helps the particles to be better dispersed in the airflow, reduces the aggregation of the particles, and thus improves the separation efficiency.

[0063] The centrifugal force generated by the rotating airflow and the turbulence intensity jointly act on the particles, making the particles more easily separated out, further improving the separation efficiency of the cyclone separator, especially when processing fine particles generated in the spraying process.

The gas or liquid containing heat after heat exchange is discharged through the first liquid outlet 220;

[0070] By heating the gas containing impurities, the density of the gas can be reduced, and the rotational gas flow formed in the cyclone separator after heating has higher kinetic energy, thereby enhancing the centrifugal force, making it easier for particles to be thrown to the wall, improving the separation efficiency. Heating can improve the dispersibility of particles in the gas, reduce the aggregation of particles, and make the particles more evenly distributed in the gas flow, thereby further improving the separation effect.
