Drawings
Fig. 1 is a front view of the overall structure of the present invention.
Illustration of the drawings:
the cabinet body 1, cabinet door 2, sliding door 3, operation mesa 4, replacement air supplement device 5, water system device 6, honeycomb deodorization filter device 7, spray set 8, photolysis device 9, fixed direction drainage plate 10, free direction drainage plate 11, slot 12.
Detailed Description
Referring to fig. 1, the photolysis displacement ventilation cabinet for the laboratory comprises a cabinet body 1, a cabinet door 2, a sliding door 3 and an operation table top 4, wherein the cabinet door 2 is rotatably connected to the lower left of the cabinet body 1 through a hinge, the sliding door 3 is slidably embedded into the left side inside the cabinet body 1, and the operation table top 4 is transversely installed in the middle of the cabinet body 1;
the replacement air supplement device 5 is installed respectively to the end about the cabinet body 1 bottom, and water system device 6, supreme honeycomb deodorization filter device 7, spray set 8 and the photodissociation device 9 of installing are down followed to the right side of the 1 inner wall of the cabinet body, and the vertical fixed direction drainage plate 10 of installing in top right side of operation mesa 4.
In this embodiment, free direction drainage plate 11 is installed to fixed direction drainage plate 10's left side top, the horizontal trompil in fixed direction drainage plate 10 bottom is provided with the inlet port, the inlet port setting is in honeycomb deodorization filter 7's left side below, when gaseous gushes on the right side that gets into fixed direction drainage plate 10, can pass through honeycomb deodorization filter 7's filtration, spray through spray set 8 again and carry out secondary filter, later carry out gaseous purification by photolysis device 9 and discharge again, further optimized laboratory operational environment.
In this embodiment, the upper right side opening of operation mesa 4 is provided with slot 12, and slot 12 sets up in the bottom of honeycomb deodorization filter 7, and the right side of slot 12 transversely inserts and is equipped with the fluid-discharge tube, and the condensation dropping liquid that produces because of the difference in temperature can effectually fall into slot 12 along fixed direction drainage plate 10, is convenient for more follow-up clear up the condensation dropping liquid at the cabinet body 1.
