Detailed Description

Example 1

As shown in fig. 1 to 3, the device comprises a box body 1, a box cover 2, an air inlet pipe 3, a flow reducing pipe 4, an air outlet pipe 5, a liquid inlet pipe 6, a motor 7, a fan 8, an atomizing nozzle 9, a filter plate mounting groove 10 and a filter plate 11; the box cover 2 is arranged at the top of the box body 1; the air inlet pipe 3 is arranged in the center of the right side wall of the box body 1; the flow reducing pipe is arranged on the air inlet pipe 3; the air outlet pipe 5 is arranged in the center of the left side wall of the box body 1; the liquid inlet pipe 6 is arranged on the upper surface of the box cover 2; the motor 7 is arranged in the center of the outer part of the rear side surface of the box body 1; the fan 8 is arranged in the box body 1 and on the shaft of the motor 7; the atomization nozzle is arranged in the box body 1, and the outlet of the liquid inlet pipe 6 is arranged; the filter plate mounting groove 10 is arranged on the lower surface of the box cover 2; the filter plate 11 is installed in the filter plate mounting groove 10.

As a preferred technical scheme of the utility model, a sealing ring is arranged at the bottom of the case cover 2; the number of the motor 7, the fan 8 and the atomizing nozzle 9 is three; the filter plate mounting grooves 10 and the filter plates 11 are two in number; the width of the filter plate 11 is the same as that of the interior of the box body 1.

The utility model discloses the theory of operation: connecting a waste gas collecting pipe of a printing machine with a flow reducing pipe 4, enabling printing waste gas to enter a box body 1 through the flow reducing pipe 4 in a speed reducing mode, starting a motor 7 to drive a fan 8 to rotate, connecting a liquid inlet pipe 6 with an ozone solution, starting an external pump to drive the ozone solution into the box body 1 through an atomizing nozzle 9, enabling the waste gas to circularly move in the box body 1 and repeatedly pass through a filter plate 11 for adsorption, dissolving water-soluble gas in the waste gas into the ozone solution, oxidizing organic matters and partial inorganic matters in the waste gas by ozone, and increasing the adsorption efficiency of the waste gas; after full adsorption and filtration, the external fan pumps out the gas in the box body 1 through the gas outlet pipe 5.
