Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a drawer-type horizontal washing tower for treating sulfur-containing and nitrogen-containing organic pollutants in a sewage station. Background Art

[0002] During the operation of sewage treatment plants, organic pollutants (gases) containing sulfur, nitrogen or poor water solubility will be generated; for the treatment of such organic pollutants, water spraying and acid-base spraying are usually used to spray the waste gas of sewage treatment plants, which will generate more reagent investment fees and its operating costs are high. Secondly, biological treatment methods can also be used, such as biological filters, but biological filters require a longer residence time. Compared with spray towers, the equipment is larger in size. At the same time, biological filters need to be equipped with more fillers and need to be supplemented with bacteria regularly. Therefore, the investment and operating costs of this biological method are very high.

[0003] The applicant had thought of using the activated sludge in the aerobic tank for spraying treatment. However, the traditional biological scrubber is a vertical structure. If the loaded filler is attached with biofilm, the filler will be heavier and cause collapse. If the biological scrubber is made of fiberglass or the tower body is reinforced, the investment cost will be increased. In addition, the entire treatment path is short, and the reliability of waste gas treatment is reduced.

[0004] Therefore, how to provide a drawer horizontal washing tower for treating sulfur- and nitrogen-containing organic pollutants in sewage stations with a simpler and more reasonable structural design, which can reduce equipment use costs and improve the reliability of waste gas treatment has become a technical problem to be solved by technical personnel in this field. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the utility model is how to provide a drawer horizontal washing tower for treating sulfur-containing and nitrogen-containing organic pollutants in sewage stations, which has a simpler and more reasonable structural design, can reduce the cost of equipment use, and can improve the reliability of waste gas treatment.

[0006] To achieve the above-mentioned purpose, the utility model provides a drawer horizontal washing tower for treating sulfur-containing and nitrogen-containing organic pollutants in a sewage station, comprising a washing tower body, an air inlet is arranged at the lower end of one side of the washing tower body, an air outlet is arranged at the upper end of the other side of the washing tower body and is connected with a waste gas post-treatment part structure; it is characterized in that a plurality of installation openings penetrating the wall thickness are arranged vertically at intervals on the washing tower body, storage drawers are arranged one by one in the installation openings, the storage drawers are used for flatly storing fillers, and a plurality of through holes are arranged on the bottom surface of the storage drawers; a bearing support structure is arranged inside the washing tower body and respectively corresponding to the storage drawers; a spray pipe is arranged inside the washing tower and above each corresponding storage drawer and is arranged with a nozzle, and each of the spray pipes is connected to a water supply pipe.

[0007] Thus, in the above structure, a material storage drawer is installed and arranged in a plurality of installation openings arranged vertically at intervals on the tower body of the washing tower, a filler is arranged in the material storage drawer, a plurality of through holes are arranged on the inner bottom surface of the drawer, and a spray pipe is arranged above the material storage drawer, and a nozzle is arranged on the spray pipe. When the waste gas treatment is completed, after the waste gas enters from the air inlet, a part of the waste gas directly flows upward and passes through the through holes on the inner bottom surface of the lowest material storage drawer, and the filler processes it, and the nozzle above completes the spraying; the remaining part of the gas flows from one end of the lowest material storage drawer to the upper part, and then is processed and sprayed by the filler in the second material storage drawer, and then is processed in sequence and flows out from the air outlet, and then enters the waste gas post-processing part structure to complete the processing and discharge.

[0008] As an optimization, the exhaust gas post-treatment structure includes a demister, an activated carbon adsorption box, a centrifuge and a chimney; the demister air inlet end is connected to the air outlet on the washing tower body, the demister air outlet end is connected to the air inlet end of the activated carbon adsorption box, the activated carbon adsorption box air outlet end is connected to the centrifuge air inlet end, and the centrifuge air outlet end is connected to the chimney air inlet end.

[0009] In this way, the demister is set up to remove mist and prevent excessive moisture from entering the subsequent activated carbon adsorption tower; the activated carbon adsorption tower is used as a security measure to ensure that the exhaust gas is discharged in compliance with the standards, the centrifuge can better ensure the flow of exhaust gas, and the chimney completes the discharge of exhaust gas.

[0010] As an optimization, the washing tower bodies are two arranged in series.

[0011] In this way, setting up two washing tower bodies in series can more thoroughly wash the exhaust gas and ensure the reliability of exhaust gas treatment.

[0012] As an optimization, a temperature detection probe is also provided on the washing tower body.

[0013] In this way, a thermometer is set in the biological washing to monitor the internal temperature of the spray tower in real time. When the temperature is high, the tap water pipe is opened for spraying to cool down and ensure the normal operation of the biochemical system.

[0014] As an optimization, any two installation openings adjacent to each other in the vertical direction on the tower body of the washing tower are respectively opened on two paired left and right sides of the tower body of the washing tower.

[0015] In this way, the layout is more reasonable, and compared with opening the installation openings on the same side, the rigidity of the washing tower body can be better guaranteed.

[0016] As an optimization, after the storage drawer is installed in the installation opening on the washing tower body, the inner end of the storage drawer is spaced apart from the inner peripheral wall of the washing tower body to form an exhaust gas passage.

[0017] In this way, part of the exhaust gas can be better detoured, the exhaust gas treatment path can be longer, and the treatment effect can be better guaranteed.

[0018] As an optimization, the load-bearing support structure includes a plurality of support rods which are correspondingly arranged below the material storage drawer and are spaced apart along the direction in which the material storage drawer is pulled out.

[0019] In this way, the bearing support structure is arranged more simply and reasonably, and the rigidity of the washing tower body can also be improved.

[0020] As an optimization, the number of the mounting openings is three and they are arranged at intervals in the vertical direction.

[0021] In this way, the design is simpler and more reasonable.

[0022] In summary, the above structure has the following advantages:

[0023] 1. From the structural point of view, the height-to-diameter ratio is reduced, the horizontal structure is more stable, maintenance is simpler, and the investment cost is lower;

[0024] 2. The drawer type is convenient for disassembling the filler. If the filler and nozzle grow biofilm, it is convenient for replacement and cleaning;

[0025] 3. The horizontal structure has a large area, the packing layer can be thinner, and it can effectively prevent the packing from being blocked;

[0026] 4. A thermometer is set up for biological washing to monitor the internal temperature of the spray tower in real time. When the temperature is high, open the tap water pipe for spraying and cooling to ensure the normal operation of the biochemical system;

[0027] 5. Set the tap water to spray regularly to prevent the sludge concentration from being too high in the spray tower, causing blockage;

[0028] 6. Spraying sludge in aerobic pools has more advantages than general water spraying or acid-base spraying, such as reducing the input of chemicals and increasing the adsorption and decomposition of poorly water-soluble organic matter;

[0029] 7. The tail gas rises through a special structure in the scrubber to ensure that there is no short-flow;

[0030] 8. The two-stage biological scrubber can further ensure full coverage of the spray, ensuring that pollutants enter the biochemical sludge for decomposition;

[0031] 9. After two-stage washing, the product is defogged by a demister to prevent excessive moisture from entering the activated carbon adsorption tower;

[0032] 10. The activated carbon adsorption tower is used as a security measure to ensure that the exhaust gas is discharged in compliance with the emission standards. BRIEF DESCRIPTION OF THE DRAWINGS
