Description

Technical Field

[0001] The utility model relates to the technical field of industrial waste gas treatment devices, in particular to a multi-stage continuous industrial waste gas treatment device. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during the combustion of fuel and production processes within the enterprise's factory area. Before the waste gas is discharged, the particulate pollutants such as smoke and dust contained in the waste gas will be treated, generally by filtering for purification.

[0003] A multi-stage continuous industrial waste gas treatment device with publication number CN219942275U comprises a treatment box... The outer wall of the central axis is provided with a first mesh plate, an activated carbon filter plate, a second mesh plate, a desulfurization ball plate, a third mesh plate and a dust removal mesh plate. Although the device can purify the gas through activated carbon, water molecules may occupy the micropores of the activated carbon after the waste gas is sprayed, reducing the space available for adsorbing waste gas pollutants, thereby reducing its adsorption capacity. Over time, this blockage may gradually accumulate, affecting the overall performance and service life of the activated carbon plate. Humidity influence: A high humidity environment may cause the activated carbon to be in a water-containing state for a long time, which may cause the structure of the activated carbon to be gradually affected, becoming fragile or damaged. Therefore, it is necessary to design a multi-stage continuous industrial waste gas treatment device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A multi-stage continuous industrial waste gas treatment device includes a spray barrel 1 and a treatment box 10. A circulating pump 14 is provided in the treatment box 10. A dehumidification mechanism for removing water vapor in the waste gas is provided in the spray barrel 1. The dehumidification mechanism includes a demister 8 arranged in the spray barrel 1. The demister 8 has the same structure as the demister in the desulfurization tower. Two packing trays 7 and two spray trays 6 are provided in the spray barrel 1. The spray tray 6 is the same as the packing layer of the spray tower. An air inlet pipe 5 and an air outlet pipe 9 connected with the interior of the spray barrel 1 are provided on the spray barrel 1. A first filter screen 3 and a second filter screen 4 are provided in the spray barrel 1. A plurality of activated carbon filter plates 13 are provided on the inner wall of the treatment box 10. There are two activated carbon filter plates 13. An exhaust pipe 19 connected with the interior of the treatment box 10 is provided on the treatment box 10. A first maintenance plate 17 and a second maintenance plate 18 are provided on the side wall of the treatment box 10.

[0023] A sewage discharge mechanism for discharging sewage and sundries is provided under the first filter screen 3 , and the sewage discharge mechanism comprises a sewage discharge pipe 2 arranged on the first filter screen 3 , and a sealing cover is provided on the sewage discharge pipe 2 .

[0024] In the utility model, a plurality of first partitions 11 are fixedly connected inside the processing box 10, and a plurality of heating wires 16 are arranged on the first partitions 11. The heating wires 16 can heat the gas to reduce the moisture in the exhaust gas.

[0025] In the utility model, two second partitions 12 are fixedly connected to the inner wall of the processing box 10. The two second partitions 12 have different lengths. The lower second partition 12 separates the circulation pump 14, and the upper second partition 12 allows the exhaust gas to flow in the two activated carbon filter plates 13, so that the exhaust gas can be purified for a sufficiently long time.

[0026] In the utility model, a protective cover 15 is provided on the exhaust pipe 19, and the protective cover 15 can prevent dust from entering. A plurality of first partitions 11 are arranged at equal intervals.

[0027] In the utility model, the sealing cover is threadedly connected to the sewage pipe 2, which is convenient for removing the sealing cover. The second filter screen 4 is funnel-shaped, so that impurities on the second filter screen 4 can automatically enter the sewage pipe 2.

[0028] When in use, the exhaust gas enters the spray barrel 1 from the air inlet pipe 5, and the circulating pump 14 sends the water in the spray barrel 1 into the two spray plates 6. The dust particles in the dust-containing gas are blocked by the first filter screen 3. When the gravity increases, the water droplets wrapped in the pollutants fall to the bottom of the spray barrel 1 under the influence of gravity. The heavier pollutants sink to the bottom of the tower body, and the lighter pollutants float on the surface of the circulating water body. The purified gas passes through the demister 8. When the gas containing mist flows through the demister 8 at a certain speed, due to the inertial impact of the gas, the mist collides with the corrugated plate and the droplets gathered are so large that the gravity generated by itself exceeds the combined force of the rising force of the gas and the surface tension of the liquid. The droplets are separated from the surface of the corrugated plate, and the gas then enters the treatment box 10. The gas is purified through the activated carbon filter plate 13 and finally discharged from the exhaust pipe 19. In the process, the gas passing through the activated carbon filter plate 13 can be pre-dehumidified to avoid the influence of excessive moisture in the exhaust gas on the service life of the activated carbon filter plate 13.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and practical concept of the present invention, which should be covered by the protection scope of the present invention.
