Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment, specifically to a spray tower packing layer for VOC waste gas treatment. Background Technology

[0002] In the treatment of VOC-containing waste gas, spray towers are commonly used. The function of a spray tower is to remove pollutants from the waste gas by ensuring sufficient contact between the spray liquid (usually water or a chemical solution) and the waste gas through the absorption effect of the liquid. To ensure sufficient contact between the spray liquid and the waste gas, a packing layer is often installed inside the spray tower. For example, Chinese patent CN207429931U provides an integrated device for treating waste gas, dust, and spray circulating water, including a treatment tower, a sedimentation tank connected to the bottom of the treatment tower, and a circulating connection between the upper part of the treatment tower and the sedimentation tank. The spray system includes a spray pipeline, a booster pump located at the inlet of the spray pipeline, and an atomizing nozzle connected to the outlet of the spray pipeline. The atomizing nozzle includes a flat, box-shaped nozzle body and spray heads evenly spaced on the bottom surface of the nozzle body. The atomizing nozzle is located inside the treatment tower. The spray pipeline has a flow regulating valve. The sedimentation tank is a three-stage sedimentation tank, including a primary sedimentation tank, an oxygen-consuming tank, and a secondary sedimentation tank connected in sequence. A connecting port is opened between adjacent tanks, and the connecting port is located at the top of the tank. An exhaust port is opened on the top surface of the primary sedimentation tank, and an air outlet is opened on the top surface of the aerobic tank.

[0003] In order to increase the absorption effect of waste gas, spray tower devices such as those mentioned above are usually equipped with double-layer packing. In actual use, since the waste gas passes through the lower packing layer first, the lower packing layer reaches the end of its service life and needs to be replaced first. The upper and lower packing layers cannot be replaced at the same time, which increases the number of maintenance and costs. Utility Model Content

[0004] The purpose of this invention is to provide a spray tower packing layer for VOC waste gas treatment, which solves the problem that in spray towers with double packing layers, the lower packing layer reaches the end of its service life first and needs to be replaced first, and the upper and lower packing layers cannot be replaced at the same time, which increases the number of maintenance times and costs.

[0005] To achieve the above objectives, this utility model provides a spray tower packing layer for VOC waste gas treatment. The spray tower packing layer includes an outer shell, and a packing fixing frame is rotatably arranged inside the outer shell. The packing fixing frame includes a disc, and arc-shaped side plates are arranged on both sides of the disc. Two sets of support plates are arranged at intervals on the inner wall of the arc-shaped side plates. Packing layers are respectively arranged at the upper and lower ends of the packing fixing frame. The packing layer includes an outer frame and packing material arranged in the outer frame. Support portions are formed at both ends of the outer frame extending outward, and the support portions abut against the ends of the arc-shaped side plates and the support plates, respectively.

[0006] Preferably, the outer shell has an arc-shaped segment in the middle, and the arc-shaped side plate is fitted to the inner wall of the arc-shaped segment.

[0007] Preferably, the outer wall of the housing is provided with a driving mechanism, and the disk extends at least partially out of the housing, so that the driving mechanism can drive the disk to rotate.

[0008] Preferably, the drive mechanism includes a motor mounted on the housing, a drive pulley connected to the output shaft of the motor, a driven pulley connected to the disc, and a belt connecting the drive pulley and the driven pulley.

[0009] Preferably, an opening is provided on the side of the outer casing away from the disk, and a cover plate is provided on the opening.

[0010] Preferably, the cover plate is fastened to the housing by a screw assembly.

[0011] Beneficial Effects: This utility model provides a spray tower packing layer for VOC waste gas treatment. The spray tower packing layer includes an outer shell, and a packing fixing frame is rotatably arranged inside the outer shell. The packing fixing frame includes a disc, and arc-shaped side plates are arranged on both sides of the disc. Two sets of support plates are arranged vertically and vertically on the inner wall of the arc-shaped side plates. Packing layers are respectively arranged at the upper and lower ends of the packing fixing frame. The packing layer includes an outer frame and packing material arranged in the outer frame. The two ends of the outer frame extend outward to form support parts, which respectively abut against the ends of the arc-shaped side plates and the support plates. Here, a spray head is arranged above the packing layer. Waste gas enters the outer shell from below, contacts and is absorbed in the packing layer. The waste gas passes through two layers of packing material sequentially from bottom to top. Since the concentration of waste gas is higher when passing through the lower packing material, the lower packing material is more likely to reach the end of its service life and need to be replaced first. Therefore, the disc is rotated every once in a while to exchange the positions of the upper and lower packing materials, so that the two layers of packing material reach the end of their service life in about the same time period, which facilitates centralized replacement and maintenance, reducing maintenance costs and frequency.

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] like Figure 1-3 As shown: This utility model provides a spray tower packing layer for VOC waste gas treatment. The spray tower packing layer includes an outer shell 1, and a packing fixing frame is rotatably arranged inside the outer shell 1. The packing fixing frame includes a disc 8, and arc-shaped side plates 9 are arranged on both sides of the disc 8. Two sets of support plates 10 are arranged vertically and vertically on the inner wall of the arc-shaped side plates 9.

The two ends of the outer frame 11 extend outward to form support parts, and the support parts abut against the ends of the arc-shaped side plates 9 and the support plates 10, respectively. Spray heads are installed above the packing layer. Exhaust gas enters the shell from below and is absorbed by the packing layer.
