Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, specifically a waste gas treatment deodorization tower. Background Technology
[0002] Industrial production and environmental protection processes generate large amounts of waste gas containing malodorous substances such as hydrogen sulfide, ammonia, and volatile organic compounds. Direct emission of these gases can severely pollute the environment and harm human health. Currently, using chemical reagents to absorb malodorous substances from waste gas is a common deodorization method, with chemical absorption being widely used due to its high removal efficiency.
[0003] Based on the above, the inventors have discovered the following problems: During the absorption of malodorous substances, most related equipment lacks a complete reagent recycling mechanism. This results in the rich liquid (saturated or near-saturated reagent solution) after malodorous substance absorption often being directly discharged or only undergoing simple treatment, making it impossible to regenerate the absorbent and reuse it. On the one hand, this leads to a huge consumption of absorbent, significantly increasing the operating costs of waste gas treatment; on the other hand, the discharge of large amounts of waste absorbent solution also causes environmental pollution and wastes resources.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a waste gas treatment and deodorization tower in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this utility model is to provide a waste gas treatment deodorization tower to solve the problem mentioned in the background art that most of the related equipment lacks a complete reagent recycling mechanism during the absorption of odorous substances, which makes the rich liquid after absorbing odorous substances often directly discharged or only simply treated, and unable to regenerate the absorbent and reuse it.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0007] A waste gas treatment and deodorization tower includes an absorption mechanism, a regeneration mechanism, and a filtration mechanism. The absorption mechanism includes an absorption box with a liquid outlet pipe installed at its bottom and a first spray frame fitted at its upper end, the first spray frame housing a plurality of first spray pipes. The regeneration mechanism includes a regeneration box with a second spray frame fitted at its upper end, the second spray frame housing a plurality of second spray pipes, an electric heating tube installed at the bottom of the regeneration box, and a collection pipe installed at the top of the regeneration box.

The output end of the first pump is connected to the top of the processing tank via a pipe, and the input end of the first pump is connected to the bottom of the regeneration tank via a pipe.
[0009] The beneficial effect of adopting the above-mentioned further solution is that the first pump transports the regenerated liquid in the regeneration tank to the treatment tank, where it is filtered and reused for absorption, forming an absorption liquid cycle, reducing consumption and lowering costs.
[0010] Furthermore, a first filter membrane and a second filter membrane are respectively installed at the upper and lower ends of the filter box. The pore size of the first filter membrane is larger than that of the second filter membrane.

[0018] Furthermore, it also includes a collection mechanism, which includes a gas-liquid separator disposed on one side of the regeneration tank, and the input end of the gas-liquid separator is connected to one end of the collection pipe through a pipeline.
[0019] The beneficial effect of adopting the above-mentioned further scheme is that the gas-liquid separator separates the regeneration gas transported by the collection pipe, thereby separating the gas and liquid, which facilitates the compression and storage of the gas reacted in the regeneration box of the compressor, allowing the gas to be further processed and improving the resource utilization rate of the regeneration process.
[0020] Furthermore, a compressor is provided on one side of the gas-liquid separator, and the input end of the compressor is connected to the output end of the gas-liquid separator through a pipe.
[0021] The beneficial effect of adopting the above-mentioned further solution is that the gas output from the gas-liquid separator is compressed by the compressor, which is convenient for storage, transportation or subsequent processing, and improves the recycling value of the regenerated gas.

[0035] Please see Figure 1 - Figure 6 It also includes a collection mechanism 3, which includes a gas-liquid separator 301.

The waste gas in contact with the packing 105 is absorbed and deodorized. After the demister 108 removes the water mist, the purified gas is discharged through the exhaust pipe 109. The rich liquid after absorption is transported to the second spray frame 202 by the third pump 103 through the outlet pipe 102, and then enters the regeneration tank 201 through the second spray pipe 206. The electric heating tube 205 heats the rich liquid to release odorous gas. The gas enters the gas-liquid separator 301 through the collection tube 204 and is then separated and compressed and stored by the compressor 302. The regenerated absorbent is sent to the treatment tank 402 by the first pump 203. After being divided by the diversion plate 405, it is filtered in stages by the first filter membrane 406, the activated carbon filter layer 407 and the second filter membrane 408 of the filter box 404.
