In the present part panel production line, can set up the fan at the spraying chamber lateral wall, directly blow off the atomizing coating in the spraying chamber, this kind of mode has certain influence to the environment: the atomized coating discharged directly causes environmental pollution. Moreover, the current practice is poor in the discharge effect of the atomized coating.

The embodiment of the application provides a spraying purification system, as shown in fig. 1 and fig. 2, for discharging redundant atomized coating in a spraying chamber 7, the spraying purification system comprises an air supply device 1, a cyclone plate 2, a recovery tank 3 and a separation treatment device 5; the air supply device 1 is arranged at the upper part of the spraying chamber 7 and supplies air into the spraying chamber 7 to form positive pressure; the rotational flow plate 2 is arranged at the outlet of the air supply device 1, and the rotational flow plate 2 changes the air supply of the air supply device 1 into rotational airflow; the recovery tank 3 is arranged at the bottom of the spraying chamber 7, and the surplus atomized coating in the spraying chamber 7 is sent to the recovery tank 3 for filtering by the rotating airflow; the atomized coating after filtration enters a separation treatment device 5 for dust and mist separation and filtration discharge.

The air supply device 1 is arranged at the upper part of the spraying chamber 7, supplies air from top to bottom, forms micro-positive pressure in the spraying chamber 7 and sends atomized coating to the recovery tank 3 below. Light substances in the atomized coating can float and rise; the air supply device 1 and the recovery tank 3 are positioned so that the air supply direction is parallel to the movement direction of the light substances in the atomized coating, thereby improving the discharge effect of the light substances. The existing fan is arranged on the side wall of the spraying chamber, when air is blown transversely, part of light substances can be accumulated above the spraying chamber, and the cleaning effect of the spraying chamber is poor.

Set up whirl board 2 in air supply arrangement 1's export, the air supply becomes rotatory air current after whirl board 2, has stronger centrifugal action, compares the air current of directly blowing downwards, can be more comprehensive send into accumulator 3 with the atomizing coating in spray booth 7, improves the purifying effect to spray booth 7. And, after the air supply becomes rotatory air current behind whirl board 2, the collision between each other of various tiny particles of atomizing coating makes the particle diameter constantly increase, and particle quality also increases thereupon, gets into accumulator 3 under the effect of air supply more easily, improves the clean effect to atomizing coating in spray booth 7.
