The water-gas separating device of the gas circuit of the atomizer, provided by the invention, is arranged at the tail end of the connecting gas pipe, and can achieve certain effects of cooling and condensation in the process of passing high-speed high-pressure gas-liquid mixed gas through the connecting gas pipe.
According to the water-gas separation device for the gas circuit of the atomizer, provided by the invention, the whole gas circuit channel is closed, the space and the caliber of all channels can ensure the effective passing of pure high-speed and high-pressure gas, the pressure loss is small, and the normal atomization of the atomizer can be ensured.

The water-gas separation device of the gas circuit of the atomizer provided by the invention can be summarized into the following steps in use:
firstly, when high-speed and high-pressure gas-liquid mixed gas output by a pressure source sequentially passes through a connecting gas pipe and a lower cover gas inlet 5 to enter a water-gas separation device, and enters a lower end cavity 7 to expand and reduce the speed. The gas-liquid mixed gas after the speed reduction is changed to the back by the blocking of the liquid receiving baffle plate, so that larger water mist particles in the gas-liquid mixed gas can be promoted to be condensed, and because the mass distribution of the water mist particles and the mass distribution of air are uneven, the capacity expansion and the speed reduction can cause the speed change difference of the water mist particles and the air to be separated; meanwhile, when the baffle plate blocks the water mist particles from changing directions, the gas-liquid separation is further increased due to different inertia of the water mist particles and air, and the liquid is easier to attach to the baffle plate 9; after the gas-liquid mixed gas is decelerated, the liquid attached to the baffle plate can be prevented from being finely crushed by too high impact speed, and meanwhile, a part of liquid attached to the wall is prevented from being taken away by too high gas flow speed, so that the wall attachment and condensation of smaller water mist particles are facilitated, and the first-step water-gas separation is realized.
And step two, the gas after the water-gas separation in the first step moves upwards, is blocked by the baffling baffle plate and turns backwards, a small part of water mist with smaller volume taken away by the gas can be further condensed and deposited, and the water mist and the aerosol with smaller volume can be further condensed and deposited into the groove of the liquid receiving baffle plate through the microporous filtration of the microporous filter element 8 with the aperture of 2-5 microns, so that the water-gas separation in the second step is realized.
