DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a device for purifying malodorous gas with large air volume and low concentration.

[0025] The utility model provides Figure 1-2 The device for purifying low-concentration malodorous gases with a large air volume shown comprises a purification tower 1 and two layers of catalyst baffles 2 fixedly arranged inside the purification tower 1, a catalyst filler 3 is filled between the two catalyst baffles 2, two symmetrically arranged through holes are provided on the side of the purification tower 1, a sleeve 4 is rotatably sleeved on the outer sides of the two through holes, an annular groove is provided on the outer wall of the purification tower 1, the sleeve 4 is rotatably arranged in the annular groove, and two symmetrically arranged material holes are provided on the side wall of the sleeve 4, the material holes and the through holes are arranged in coordination, an ozone water tank 5 is fixedly arranged at the lower end of the side wall of the purification tower 1, and a connecting pipe 6 is connected to the top of the ozone water tank 5, and the upper end of the connecting pipe 6 passes through the purification tower 1 and is located above the catalyst baffle 2;

[0026] A bottom plate 7 is fixedly sleeved on the lower end of the outer wall of the purification tower 1 , a support frame 8 is fixedly provided on the top of the bottom plate 7 , a loading barrel 9 is fixedly provided on the top of the support frame 8 , and a loading assembly is provided inside the loading barrel 9 .

[0027] Before purifying the malodorous gas, the ozone water in the ozone water tank 5 is introduced into the purification tower 1 through the ozone tube 6, and then the malodorous gas is introduced into the purification tower 1 from the bottom of the purification tower 1. At this time, the ozone water falls and contacts the malodorous gas to purify the malodorous gas. At the same time, when the ozone water contacts the catalyst filler 3, the oxidation capacity and purification effect of the ozone water can be improved. As the purification work continues, the ring 4 can be rotated so that the material hole on the side of the ring 4 is connected with the through hole on the side of the purification tower 1, and then the unused filler is transported to between the two catalyst baffles 2 through the feeding assembly, the through hole and the material hole, and the lost filler in the catalyst baffle 2 is pushed out. After the filler is added, the ring 4 is rotated so that the ring 4 covers the through hole, so that the catalyst filler 3 can be stably used in the purification tower 1.

[0028] In order to allow the unused filler to stably enter between the two layers of catalyst retaining screen 2, as shown in FIG. Figure 1 As shown, the feeding assembly includes a screw conveyor 10, which is arranged inside the feeding barrel 9, and the lower end is rotatably connected to the bottom of the inner wall of the feeding barrel 9, and the two sides of the feeding barrel 9 are respectively connected to a feed hopper 11 and a discharge hopper 12, and the discharge hopper 12 is matched with the collar 4 and the material hole. A motor 13 is fixedly provided at the bottom of the feeding barrel 9, and the output end of the motor 13 passes through the feeding barrel 9 and is fixedly connected to the screw conveyor 10.

[0029] Put the catalyst into the feed hopper 11 and start the motor 13 so that the motor 13 drives the screw conveyor 10 to rotate. At this time, the screw conveyor 10 can push the filler and pass the filler into the through hole and the material hole through the discharge hopper 12, and finally enter the two catalyst retaining nets 2 for use.

[0030] In order to ensure that the through holes and the material holes can be separated or quickly connected before and after the addition of fillers, Figure 1-2 As shown, a transmission gear ring 14 is fixedly sleeved on the lower end of the outer wall of the collar 4, a vertical rod 15 is rotatably provided on the top of the base plate 7, a gear 16 is fixedly sleeved on the upper end of the vertical rod 15, and the gear 16 is matched with the transmission gear ring 14, a rotating block 17 is fixedly sleeved on the lower end of the vertical rod 15, an insertion rod 18 is slidably penetrated inside the rotating block 17, a pulling hole is opened on the upper end of the insertion rod 18, a positioning gear ring 19 is fixedly provided on the top of the base plate 7, the positioning gear ring 19 is sleeved on the outer side of the vertical rod 15, the insertion rod 18 is plugged into the tooth groove of the positioning gear ring 19, a spring 20 is sleeved on the upper end of the insertion rod 18, and the two ends of the spring 20 are respectively fixedly connected to the insertion rod 18 and the rotating block 17.

[0031] During the purification work, the material hole and the through hole are misaligned. At this time, the catalyst filler 3 is located in the purification tower 1 and works stably. When the filler needs to be replaced, the plug rod 18 can be pulled up through the pulling hole, so that the plug rod 18 stretches the spring 20 and is pulled out from the tooth groove of the positioning gear ring 19. Then, the vertical rod 15 is rotated by the rotating block 17, and the ring 4 is rotated with the cooperation of the gear 16 and the transmission gear ring 14, so that the material hole can be connected with the through hole. At this time, the plug rod 18 is released, and the plug rod 18 is inserted into the tooth ring 19 again under the elastic force of the spring 20 to complete the position fixation of the ring 4 and ensure the stability during the packing replacement process. After the packing is replaced, the above action is repeated to make the ring 4 rotate back to its original position.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
