Description

Technical Field

[0001] This utility model relates to the field of hydrogen sulfide removal towers, and more particularly to a biological treatment mechanism inside a hydrogen sulfide removal tower. Background Technology

[0002] Currently, hydrogen sulfide is a toxic and harmful gas that not only poses serious threats to the environment and human health, but also has a negative impact on industrial equipment and production processes. Therefore, it is particularly important to develop efficient and economical hydrogen sulfide removal technologies.

[0003] Currently, traditional hydrogen sulfide removal processes (such as alkaline washing and absorption, and catalytic oxidation) have problems such as high operating costs and high risk of secondary pollution. In order to remove hydrogen sulfide more effectively, hydrogen sulfide removal towers are generally used. Most hydrogen sulfide removal towers use biological methods to remove hydrogen sulfide. Biological desulfurization technology uses specific desulfurization bacteria to convert sulfides into elemental sulfur or sulfates at normal temperature and pressure. It has the advantages of low investment, convenient operation, and no secondary pollution.

[0004] However, most existing biological treatment mechanisms in hydrogen sulfide removal towers suffer from defects such as low gas-liquid mass transfer efficiency and easily suppressed microbial activity. Over time, biological activity is affected, making it difficult to meet the treatment needs of high-concentration and fluctuating hydrogen sulfide conditions. Utility Model Content

[0005] In order to overcome the shortcomings of existing biological treatment mechanisms in hydrogen sulfide removal towers, such as low gas-liquid mass transfer efficiency and easily inhibited microbial activity, which affect biological activity over time and make it difficult to meet the treatment requirements of high-concentration and fluctuating hydrogen sulfide conditions.

[0006] The technical solution of this utility model is as follows: a biological treatment mechanism inside a hydrogen sulfide removal tower, including a mounting bracket 1, a mounting bracket 2 provided on the lower side of the mounting bracket 1, a biological packing cylinder 1 provided on the upper side of the mounting bracket 1, a biological packing cylinder 2 corresponding to the biological packing cylinder 1 provided on the upper side of the mounting bracket 2, biological packing layers provided inside the biological packing cylinder 1 and biological packing cylinder 2, a liquid collection tank provided on the upper side of the biological packing cylinder 2, a flow guide hood fixedly installed at the upper end of the liquid collection tank, an oxygen cylinder provided on the outer side of the biological packing cylinder 1 and biological packing cylinder 2, an oxygen supply main pipe detachably installed on the upper end of the oxygen cylinder, a three-way valve provided at the end of the oxygen supply main pipe, an oxygen supply pipe 1 detachably installed on the upper end of the three-way valve, an oxygen supply pipe 2 detachably installed on the lower end of the three-way valve, and an exhaust hood fixedly connected to the ends of the oxygen supply pipe 1 and oxygen supply pipe 2.

[0007] As a preferred option, when the biological activity is low, the valves on the main oxygen supply pipe, oxygen supply pipe one, and oxygen supply pipe two can be opened to transport the oxygen in the oxygen cylinder to the outlet hood through the oxygen supply pipeline, and then discharge it from the upper and lower sides of the outlet hood. This can supply oxygen to the biological packing layer inside biological packing cylinder one and biological packing cylinder two, thereby maintaining the optimal metabolic state of microorganisms and preserving their biological activity.

[0008] Preferably, oxygen supply pipe one and oxygen supply pipe two extend into the interior of the biological packing layer, and the surfaces of biological packing cylinder one and biological packing cylinder two are respectively provided with through holes corresponding to oxygen supply pipe one and oxygen supply pipe two.

[0009] Preferably, the vent hood is positioned in the middle of biological packing cylinder one and biological packing cylinder two, and through slots are provided on the upper and lower sides of the vent hood.

[0010] Preferably, a fixing frame 1 is fixedly installed at the lower end of biological packing cylinder 1 and biological packing cylinder 2, and a fixing frame 2 is fixedly installed at the upper end of biological packing cylinder 1 and biological packing cylinder 2.

[0011] Preferably, filter plates are fixedly connected to the inner walls of fixed frame one and fixed frame two, and the surface of the filter plates is provided with evenly distributed air vents.

[0012] Preferably, the guide shroud is shaped like an inverted funnel, and the surface of the liquid collection tank has a circular groove corresponding to the guide shroud.

[0013] As a preferred option, valves are installed on the main oxygen supply pipe, oxygen supply pipe one, and oxygen supply pipe two.

[0014] The beneficial effects of this utility model are:

[0015] 1. The biological treatment mechanism inside the hydrogen sulfide removal tower is equipped with oxygen cylinders, oxygen supply pipelines, and an exhaust hood. When biological activity is low, the valves on the main oxygen supply pipe, oxygen supply pipe one, and oxygen supply pipe two can be opened to deliver oxygen from the oxygen cylinders to the exhaust hood through the oxygen supply pipelines. The oxygen is then discharged from the upper and lower sides of the exhaust hood, which can supply oxygen to the biological packing layers inside biological packing cylinder one and biological packing cylinder two, thereby maintaining the optimal metabolic state of microorganisms and preserving their biological activity to meet the treatment requirements of high-concentration and fluctuating hydrogen sulfide conditions.

[0016] 2. The biological treatment mechanism inside the hydrogen sulfide removal tower optimizes the gas-liquid flow path by setting up a liquid collection tank and a flow guide hood, thereby extending the gas phase residence time and thus treating hydrogen sulfide more thoroughly, achieving direct coupling between waste gas and the bioreactor.

[0024] Please see Figures 1-5 This utility model provides an embodiment: a biological treatment mechanism inside a hydrogen sulfide removal tower, including a mounting bracket 1, a mounting bracket 2 on the lower side of the mounting bracket 1, a biological packing cylinder 51 on the upper side of the mounting bracket 1, and a biological packing cylinder 52 corresponding to the biological packing cylinder 51 on the upper side of the mounting bracket 2. A biological packing layer 6 is provided inside both the biological packing cylinder 51 and the biological packing cylinder 52. A liquid collection tank 3 is provided on the upper side of the biological packing cylinder 52, and a flow guide is fixedly installed at the upper end of the liquid collection tank 3. Oxygen cylinders 7 are installed on the outside of the cover 4, biological packing cylinder 1 51 and biological packing cylinder 2 52. An oxygen supply main pipe 8 is detachably installed on the upper end of the oxygen cylinder 7. A three-way valve 9 is installed at the end of the oxygen supply main pipe 8. An oxygen supply pipe 1 10 is detachably installed on the upper end of the three-way valve 9. An oxygen supply pipe 2 11 is detachably installed on the lower end of the three-way valve 9. An exhaust hood 12 is fixedly connected to the ends of the oxygen supply pipe 1 10 and the oxygen supply pipe 2 11. The exhaust hood 12 can ensure that oxygen can be supplied to the organisms from inside the biological packing cylinder 1 51 and the biological packing cylinder 2 52.

[0025] Please see Figures 2-4Oxygen supply pipe 10 and oxygen supply pipe 21 extend into the interior of the biological packing layer 6. Biological packing cylinder 11 and biological packing cylinder 22 have through holes corresponding to oxygen supply pipe 10 and oxygen supply pipe 21 on their surfaces, respectively. An exhaust hood 12 is positioned in the center of biological packing cylinder 11 and biological packing cylinder 22. Through slots are provided on the upper and lower sides of the exhaust hood 12. A fixing frame 13 is fixedly installed at the lower end of biological packing cylinder 11 and biological packing cylinder 22. A fixing frame 54 is fixedly installed at the upper end of the second material cylinder 52. Filter plates 55 are fixedly connected to the inner walls of the first fixing frame 53 and the second fixing frame 54. The surface of the filter plate 55 is provided with evenly distributed air vents. Valves are installed on the oxygen supply main pipe 8, the first oxygen supply pipe 10 and the second oxygen supply pipe 11. Oxygen in the oxygen cylinder 7 is transported to the outlet hood 12 through the oxygen supply pipeline and then discharged from the upper and lower sides of the outlet hood 12, which can supply oxygen to the biological packing layer 6 inside the first biological packing cylinder 51 and the second biological packing cylinder 52.

[0026] Please see Figure 5 The guide shroud 4 is shaped like an inverted funnel, and the surface of the liquid collection tank 3 is provided with a circular groove corresponding to the guide shroud 4, which can optimize the gas-liquid flow path and extend the gas phase residence time.

[0027] During operation, the entire biological treatment mechanism inside the hydrogen sulfide removal tower is first installed inside the tower and secured with bolts. After securing, an inspection port is set on the outside of the tower corresponding to the biological treatment mechanism. After setting it, an inspection plate is installed. Then, the oxygen supply main pipe 8 and the oxygen cylinder 7 are connected together. When the biological activity is low, the valves on the oxygen supply main pipe 8, oxygen supply pipe 10, and oxygen supply pipe 21 can be opened to deliver oxygen from the oxygen cylinder 7 to the outlet hood 12 through the oxygen supply pipeline. The oxygen is then discharged from the upper and lower sides of the outlet hood 12, which can supply oxygen to the biological packing layer 6 inside the biological packing cylinder 1 51 and biological packing cylinder 2 52.

[0028] Through the above steps, by setting up oxygen cylinder 7, oxygen supply pipeline and gas outlet hood 12, when the biological activity is low, the valves on the main oxygen supply pipe 8, oxygen supply pipe one 10 and oxygen supply pipe two 11 can be opened to transport the oxygen in oxygen cylinder 7 to the gas outlet hood 12 through the oxygen supply pipeline, and then discharged from the upper and lower sides of the gas outlet hood 12. This can supply oxygen to the biological packing layer 6 inside biological packing cylinder one 51 and biological packing cylinder two 52, thereby maintaining the optimal metabolic state of microorganisms. This solves the problem that most existing biological treatment mechanisms in hydrogen sulfide removal towers have defects such as low gas-liquid mass transfer efficiency and easy inhibition of microbial activity. Over time, the biological activity is affected, making it difficult to meet the treatment needs of high concentration and fluctuating hydrogen sulfide conditions.
