Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a tar waste gas treatment device. Background Technology

[0002] The manufacturing process generates a large amount of waste gas, some of which contains tar. Since tar is gaseous at high temperatures but condenses into liquid at low temperatures (generally below 200°C), its separation and treatment are very difficult. As a result, the gas pipeline is prone to blockage over time. This not only affects the exhaust gas but also the processing of products and the stable operation of equipment. Therefore, it is necessary to treat the tar in the tar-containing waste gas in advance to reduce its impact on subsequent waste gas treatment equipment and pipelines. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a tar exhaust gas treatment device, which solves the problem that when exhaust gas containing tar vapor is transported in the existing manner, the tar vapor liquefies into tar, and the tar easily clogs the gas delivery pipeline.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A tar exhaust gas treatment device includes a treatment tank. Multiple ceramic filter plates are arranged radially in the inner cavity of the treatment tank. Ceramic packing channels are provided on the ceramic filter plates. Multiple circumferential grooves are arranged at equal intervals on the inner wall of the treatment tank. An axial groove is formed on the inner wall of the treatment tank along the axial direction. The axial groove passes through all the circumferential grooves along the axial direction and communicates with them. A drain port is formed on the treatment tank and communicates with one end of the axial groove.

[0006] Preferably, a differential pressure gauge is arranged at the outlet of the treatment tank.

[0007] Preferably, the ceramic packing channel uses ceramic rectangular saddle rings as packing.

[0008] Preferably, the processing tank is symmetrically arranged with inspection doors, each inspection door is equipped with a mating plate, and the processing tank is equipped with an extension plate. The extension plate and the mating plate are fixedly connected by fasteners.

[0009] Preferably, a rotating connecting base is fixedly provided on the outer surface of the treatment tank, and the two sides of the inspection door are rotatably connected to the rotating connecting base. A handle is provided on the outer surface of the inspection door.

[0010] This utility model has the following beneficial effects:

[0011] This tar exhaust gas treatment device, through its intricate ceramic packing channels and ceramic filter plates, utilizes the complex internal pores and high surface tension. Due to the different densities and surface tensions of the various components in the exhaust gas, when oil mist exhaust gas passes through the device, the oil mist accumulates on the ceramic filter plates and packing channels, forming droplets. Through the circumferential and axial grooves, some droplets drip into the circumferential groove under the action of gravity, collect and discharge into the axial groove, and then exit from the drain outlet.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 This utility model provides a technical solution: a tar waste gas treatment device, including a treatment tank 1. Multiple ceramic filter plates 2 are arranged radially in the inner cavity of the treatment tank 1. Ceramic filter plates 2 are provided with ceramic packing channels 3. Multiple circumferential grooves 4 are arranged at equal intervals on the inner wall of the treatment tank 1. An axial groove 5 is opened on the inner wall of the treatment tank 1 along the axial direction. The axial groove 5 passes through all the circumferential grooves 4 along the axial direction and is connected to the circumferential grooves 4. A drain port 6 is opened on the treatment tank 1 and is connected to one end of the axial groove 5.

[0019] In this technical solution, the ceramic packing channel 3 and ceramic filter plate 2 are designed to utilize the complex internal channels and high surface tension. Due to the different densities and surface tensions of different components in the exhaust gas, when oil mist exhaust gas passes through the device, the oil mist will accumulate on the ceramic filter plate 2 and ceramic packing channel 3, forming droplets. Through the circumferential groove 4 and axial groove 5, some droplets fall into the circumferential groove 4 under the action of gravity, collect and discharge into the axial groove 5, and then be discharged from the drain outlet 6.

[0020] Because some oil droplets will remain on the surface of the ceramic filter plate 2 and the ceramic packing channel 3, over time the oil droplets will block the internal channels of the ceramic. In this embodiment, a differential pressure gauge 7 is arranged at the outlet of the treatment tank 1. Figure 2 and 4 As shown, the pressure at the outlet is detected by the differential pressure gauge 7. Since the pressure at the inlet is constant, the pressure difference across the treatment tank 1 is compared with the pressure value set by the control system. If it exceeds the allowable range of the set value, an alarm signal is output. When the system receives the alarm signal, the ceramic filter plate 2 and the ceramic packing channel 3 need to be replaced or cleaned.

[0021] In this embodiment, ceramic rectangular saddle rings are used as packing in the ceramic packing channel 3. The shape of the ceramic rectangular saddle ring is between that of a ring and a saddle. This structure is beneficial for liquid distribution and increases gas passage, which can effectively improve the efficiency of oil mist treatment in exhaust gas.

[0022] like Figure 1 and 2 As shown in this embodiment, inspection doors 9 are symmetrically arranged on the treatment tank 1, and mating plates 10 are arranged on the inspection doors 9. Extension plates 8 are arranged on the treatment tank 1, and the extension plates 8 and mating plates 10 are fixedly connected by fasteners. The inspection doors 9 facilitate the cleaning of the ceramic filter plates 2 and the ceramic packing channels 3, thereby improving the ceramic's efficiency in treating waste gas, preventing blockages, and reducing the impact of oil mist in the waste gas on downstream components, thus improving the quality of waste gas treatment.

[0023] like Figure 2 and 3 As shown, in this embodiment, a rotating connecting base 12 is fixedly provided on the outer surface of the treatment tank 1, and the two sides of the inspection door 9 are rotatably connected to the rotating connecting base 12. A handle 11 is provided on the outer surface of the inspection door 9. The rotatingly arranged inspection door 9 can be easily opened temporarily to clean the inner cavity of the treatment tank 1.
