Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for thermal production. Background Art

[0002] In order to meet the stringent environmental requirements for tail gas emissions in, for example, the chemical industry, it is necessary to remove toxic and harmful components in the tail gas. Among them, the use of specific solutions to remove pollutants in the tail gas by wet absorption reaction is a method widely used in the chemical industry; however, this wet absorption mainly uses a huge spray absorption packed tower, which has the advantages of being simple and convenient like a static method, but the space utilization efficiency is not high, and it is difficult to directly treat many pollutants to a level that meets the current stringent standards.

[0003] According to the principle of wet absorption of exhaust gas, the exhaust gas is directly introduced into the solution and stirred at high speed by mechanical force to continuously disperse the gas into small bubbles in the solution, thereby increasing the contact area and contact time between the gas and the solution, allowing the gas and the solution to fuse and then produce a chemical reaction, thereby achieving the removal of trace harmful gases contained in the exhaust gas.

[0004] However, chemical waste gas contains not only trace harmful gases, but also mostly fine harmful particles. In addition, in some cases, trace components in waste gas will generate solid precipitates after reacting with specific solutions. As a result, when the soluble solution is filtering and removing waste gas, harmful particles and solid precipitates in the waste gas will remain in the solution. During long-term use, the soluble solution will be polluted and become turbid or even produce sludge, and the polluted solution will reduce the efficiency of purifying waste gas. To solve this problem, traditional technical solutions are mostly to replace the solution, which leads to increased costs. At the same time, when the old solution is discharged, the particulate impurities in the solution will be adsorbed on the bottom of the inner wall of the reaction cylinder, which is easy to continue to pollute the newly added solution, thereby affecting the efficiency and quality of waste gas treatment.

[0005] In order to solve the above problems, we propose a waste gas treatment device for thermal production to solve the above problems. Summary of the invention

At the same time, by providing a cleaning mechanism, the inner wall of the reaction cylinder can be flushed and cleaned to prevent particulate sediment from remaining in the reaction cylinder and causing re-contamination of the newly added solution.

A connecting pipe 10 is provided at the funnel of the guide groove 9. A valve is provided at the inlet of the connecting pipe 10. The bottom end of the connecting pipe 10 is connected with the top of the filter box 12. The particle sediment inside the reaction cylinder 1 can be guided by the guide groove 9. Under the flow of the solution, the particle sediment will gather at the bottom of the funnel of the guide groove 9, and then be guided to the filter box 12 through the connecting pipe 10 for filtration.

[0034] In some examples, two sets of inspection doors 25 are provided in the middle of the upper end of the box body 11. The two sets of inspection doors 25 are respectively opened on the top of the filter box 12 and the sedimentation box 13. Opening the inspection doors 25 makes it convenient for staff to clean the inner cavity of the filter box 12 and the sedimentation box 13.

[0037] Example 3: Reference Figure 1 - Figure 6 As shown, based on Embodiment 1-2, a waste gas treatment device for thermal production also includes the following structure: The cleaning mechanism is arranged on the inner side of the reaction tube 1. The cleaning mechanism includes two groups of spray pipes 24. The two groups of spray pipes 24 are arranged on the inner upper end of the reaction tube 1 and are respectively fixedly installed on the inner walls at both ends of the reaction tube 1. A spray hole is opened on one side of the spray pipe 24. The spray hole is close to the wall of the reaction tube 1. The inlet end of the spray pipe 24 is connected to a water pump and a liquid extraction pipe 23. The inlet end of the liquid extraction pipe 23 is arranged at the inner bottom of the sedimentation tank 13.

[0038] The solution precipitated in the sedimentation box 13 is extracted by a water pump, then transported to the spray pipe 24, and finally sprayed out from the spray hole, so as to spray and flush the inner wall of the reaction tube 1, and then cooperate with the filtering mechanism to achieve the purpose of cleaning the inner cavity of the reaction tube 1, so as to avoid the particle sediment remaining in the reaction tube 1 to contaminate the newly added solution.

[0039] The working principle of the present invention is: When it is necessary to treat the waste gas generated in thermal production, a soluble solution needs to be added to the reaction cylinder 1, and then the waste gas is transported to the reaction cylinder 1 through the air inlet pipe 2 by an air pump to mix and react with the solution. During the mixing reaction, the servo motor 5 is started to drive the rotating shaft 4 to rotate, thereby driving the multiple sets of spiral conveying blades 6 to rotate, so as to push the solution in the reaction cylinder 1 from left to right. During the flow of the solution, it will pass through the multiple sets of leak plates 7 and the multiple sets of crushing blades 8 in sequence, so as to realize multiple segmentation and crushing of bubbles generated when the waste gas and the solution are mixed, so that large bubbles are split into small bubbles, so that the waste gas and the solution are fully mixed and reacted, thereby improving the efficiency of removing harmful substances in the waste gas; In addition, when the solution in the reaction cylinder 1 becomes turbid or even produces sludge impurities due to repeated use, the valve at the connecting pipe 10 at the bottom of the reaction cylinder 1 is opened, and the solution will flow into the filter box 12 along the connecting pipe 10 for process sedimentation, and then continue to be extracted and used, thereby filtering and purifying the solution, improving the cleanliness of the solution, and thus maintaining the efficiency and quality of filtering and purifying the exhaust gas.

[0040] The specific process is that when the solution enters the filter box 12, the impurities in the solution are first filtered and separated by the filter plate 14, and the filtered solution falls into the filter box 12 for precipitation, and then flows into the precipitation box 13 through the filter screen 18 for precipitation and storage again; At the same time, the solution stored in the sedimentation box 13 can be extracted through the water pump and the liquid extraction pipe 23 and transported to the two groups of spray pipes 24. After the solution enters the spray pipe 24, it will be sprayed out from the spray hole opened at the side end of the spray pipe 24, so as to spray and rinse the inner wall of the reaction cylinder 1, avoid dirt and impurities remaining on the inner wall of the reaction cylinder 1, causing pollution to the newly added solution, and flush the inner wall of the reaction cylinder 1, and then gather it into the filter box 12 through the guide groove 9 for filtration and purification. According to the above process, the inner wall of the reaction cylinder 1 is sprayed and flushed for multiple cycles, so as to clean the reaction cylinder 1, and at the same time, the solution is filtered and purified, so as to improve the cleanliness of the inner cavity of the reaction cylinder 1 and the purity of the solution, and avoid the particle sediment sludge remaining in the reaction cylinder 1 to pollute the solution, resulting in affecting the efficiency and quality of exhaust gas treatment.
