Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection engineering, and particularly relates to an environmental protection device for purifying waste gas used in industrial production. Background Art

[0002] Industrial waste gas contains a large amount of acidic and alkaline elements, which is one of the main sources of water pollution and air pollution. The existing industrial waste gas treatment method is to dilute it so that the content of harmful substances in industrial waste gas can be reduced to environmental protection emission standards.

[0003] According to the public disclosure, an industrial waste gas purification and environmental protection device (publication number: CN 208097767U) includes an air intake pipe, a protective cover shell, a motor, a base, a ventilation hose, a support frame, a purification ion box, an air outlet pipe, a protective fence, and a ladder frame. The bottom end of the air intake pipe is connected to the top end of the connecting cover. The utility model is an industrial waste gas purification and environmental protection device, which is structurally provided with a purification ion box. When the waste gas treatment device is used, the waste gas enters the coarse filter screen through the connection relationship between the ventilation hose and the connecting pipe. Under the action of the oil removal layer and the high-energy plasma layer, the pollutant molecules are decomposed in a very short time, and various subsequent reactions occur to achieve the purpose of decomposing pollutants and removing odors. After that, the gas is further photocatalyzed by the ultraviolet light decomposition chamber, and the activated carbon fiber filter layer achieves the effect of purifying the waste gas. In this way, through the action of ions and photolysis, the polluted waste gas can be quickly purified, and the generated gas has no odor.

[0004] However, in the above application, the exhaust gas cannot be purified multiple times through the cooperation between the ventilation hose and the connecting pipe assembly. Long-term use will result in incomplete purification of the gas and unsatisfactory results. Utility Model Content

[0026] The purification device 5 includes a motor 51, which is arranged above the base plate 1. A water tank 52 is fixedly connected to the top of the treatment box 2. A rotating shaft 53 is fixedly connected to the output shaft of the motor 51. The circumferential surface of the rotating shaft 53 is rotatably connected to the inside of the water tank 52. A water inlet 54 is provided on the top of the water tank 52. A water outlet 55 is provided on the top of the water tank 52. A rack groove 56 is provided on the inner wall of the water tank 52.

A half gear 58 is fixedly penetrated on the circumferential surface of the rotating shaft 53, and the side surface of the rack 57 is meshed with the circumferential surface of the half gear 58.

[0027] As shown in the figure, a spring hole 59 is opened on the inner wall of the water tank 52, and a spring 510 is fixedly connected to the inner wall of the spring hole 59. One end of the spring 510 away from the spring hole 59 is fixedly connected to the side of the rack 57. This design is conducive to achieving the resetting effect of the rack 57 through the spring 510.

[0028] As shown in the figure, a gauze 511 is fixedly connected to the inside of the water tank 52, an activated carbon layer 512 is fixedly connected to the side of the gauze 511, a drainage groove 513 is provided at the bottom of the water tank 52, and a waste water tank 514 is fixedly connected to the side of the bottom plate 1. This design is conducive to achieving multiple purification effects through the activated carbon layer 512.

[0029] As shown in the figure, the side of the rack 57 is elastically connected to the inner wall of the spring hole 59 through the spring 510, and the number of the gauze 511 is set to two, and they are symmetrical to each other along the vertical center axis of the activated carbon layer 512. This design is conducive to fixing the activated carbon layer 512 through the gauze 511 on both sides.

[0030] As shown in the figure, a ventilation device 6 is provided on the top of the base plate 1, and the ventilation device 6 includes a fan frame 61. The bottom of the fan frame 61 is fixedly connected to the top of the base plate 1, and the inside of the fan frame 61 is rotatably connected to a rotating shaft 62. A first belt groove 63 is provided on the circumferential surface of the rotating shaft 53, and a second belt groove 64 is provided on the circumferential surface of the rotating shaft 62. A belt 65 is transmission-connected to the circumferential surface of the first belt groove 63, and the inner side surface of the belt 65 is on the circumferential surface of the second belt groove 64. Blades 66 are fixedly connected to the circumferential surface of the rotating shaft 62. This design is conducive to the transmission of the belt 65, so that the rotating shaft 62 is driven to rotate when the rotating shaft 53 rotates.

[0031] As shown in the figure, a vent 67 is provided on the side of the processing box 2, and a limiting plate 68 is fixedly connected to the side of the processing box 2. A slide groove 69 is provided on the side of the limiting plate 68, and a slider 610 is slidably connected inside the slide groove 69.

[0033] A specific application of this embodiment is: when it is necessary to purify the exhaust gas, first let the exhaust gas enter the treatment box 2 through the air inlet 3, and then start the motor 51. When the motor 51 is started, the shaft 53 on the output shaft of the motor 51 rotates clockwise. When the shaft 53 rotates clockwise, the half gear 58 on the shaft 53 intermittently meshes with the rack 57. When the half gear 58 meshes with the rack 57, the water outlet 55 opens. When the water outlet 55 is opened, the water inside the water tank 52 flows out to filter the water-soluble substances in the gas. The gas then passes through the gauze 511 into the activated carbon layer 512, and the impurities are adsorbed by the activated carbon layer 512. The purified gas is discharged through the exhaust pipe 4. When the shaft 53 rotates counterclockwise, the half gear 58 on the shaft 53 cannot intermittently mesh with the rack 57, and purification cannot be performed at this time.

[0034] After the purification is completed, the gas inside the processing box 2 needs to be cleaned. First, start the motor 51. When the motor 51 is started, the shaft 53 on the output shaft of the motor 51 rotates clockwise. When the shaft 53 rotates clockwise, the rotating shaft 62 driven by the belt 65 and the shaft 53 rotates clockwise. When the rotating shaft 62 rotates clockwise, the blades 66 on the rotating shaft 62 ventilate the inside of the processing box 2 through the vent 67. When the shaft 53 rotates counterclockwise, the rotating shaft 62 driven by the belt 65 and the shaft 53 rotates counterclockwise. When the rotating shaft 62 rotates counterclockwise, the blades 66 on the rotating shaft 62 cannot ventilate the inside of the processing box through the vent 67.
