Technical Field

[0001] This utility model relates to the field of environmental protection, and more specifically, to a composite waste gas treatment spray tower. Background Technology

[0002] As a core piece of equipment for industrial waste gas treatment, spray towers hold an important position in the environmental protection field. With increasingly stringent requirements for waste gas treatment, the spray tower industry has ushered in new development opportunities.

[0003] A search revealed that Chinese Patent Publication No. CN212942200U discloses "a waste gas treatment spray tower, comprising a spray tower body; a mounting cover fixedly installed within the spray tower body; a filter plate fixedly installed on one inner wall of the mounting cover and fixedly connected to the spray tower body; a cleaning mechanism disposed on the spray tower body; a baffle fixedly installed on the bottom inner wall of the mounting cover; multiple through holes, all of which are formed on the baffle; two discharge holes, both of which are formed at the bottom of the mounting cover; and a sealing mechanism disposed within the mounting cover. This waste gas treatment spray tower provided by this utility model has the advantages of facilitating pre-treatment of waste gas, achieving good cleaning effect of impurities in the waste gas, and facilitating discharge." However, it still has the following drawbacks:

[0004] (1) The spray area is uneven, the gas-liquid contact is insufficient, and some waste gas cannot be effectively purified, making it difficult to meet the quality of the discharged gas and failing to meet the established environmental protection requirements and emission standards.

[0005] (2) After treatment, the pollutant content of some spray liquid can be reduced to a level that meets the reuse standard and is feasible to be put back into use. If such spray liquid is discharged directly without effective treatment, the residual chemical substances, particulate matter and other pollutants inside will make it wastewater. Therefore, a composite waste gas treatment spray tower is proposed. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By setting up a spray assembly, when in use, exhaust gas is introduced into the interior of the spray tower through the air inlet. The first water pump draws spray liquid from the storage tank, transports it through the first water pipe to four second water pipes, and then from the four second water pipes to four cross water pipes. The four cross water pipes transport the spray liquid to each rotating nozzle, and finally the spray liquid is sprayed out through each rotating nozzle. The rotation of the rotating nozzles makes the coverage of the spray liquid more uniform. The spray liquid and exhaust gas are purified through gas-liquid contact. The purified gas is discharged through the air outlet, and the used spray liquid falls to the bottom of the spray tower.

[0018] 2. By setting up a circulating filtration assembly, the used spray liquid is transported to the third water pipe by the second water pump during use, and then undergoes preliminary filtration through the filter screen. After further filtration through the filter screen, various impurities are removed, and finally it flows out into the storage tank. The pH value in the storage tank is measured by a pH meter. When the pH value does not meet the requirements, a signal is transmitted to the PLC controller to control the opening and closing of the two valves in the mixing tank to control the pH value of the spray liquid.

[0031] like Figure 1 As shown, this embodiment proposes a composite waste gas treatment spray tower, including a base plate 1, a spray assembly 2 for treating waste gas is provided at one end of the base plate 1, and a circulating filter assembly 3 for recycling the spray liquid is installed around the spray assembly 2.

[0032] like Figure 3 , Figure 4 and Figure 6 As shown, the spray assembly 2 includes four support columns 201 disposed at one end of the base plate 1. A spray tower 202 is welded to the top of each of the four support columns 201. A liquid storage tank 203 is disposed at the end of the base plate 1 away from the spray tower 202. A first water pump 204 is installed at the bottom of the liquid storage tank 203. A first water pipe 205 is installed at the outlet of the first water pump 204. Four second water pipes 206 are installed on one side of the first water pipe 205, penetrating the spray tower 202 and extending into its interior. A cross-shaped water pipe 207 is installed at one end of each of the four second water pipes 206. Four rotating nozzles 208 are installed at the outlets of the four cross-shaped water pipes 207 for uniformly spraying the spray liquid. Four perforated plates 209 are welded inside the spray tower 202 to enhance the contact effect between the exhaust gas and the spray liquid. Plate 209 is located on top of the four cross-shaped water pipes 207. An air inlet 210 is welded to one side of the bottom of the spray tower 202, and an air outlet 211 is welded to the top of the spray tower 202. During use, exhaust gas is introduced into the interior of the spray tower 202 through the air inlet 210. The first water pump 204 draws spray liquid from the storage tank 203, transports it through the first water pipe 205 to the four second water pipes 206, and then from the four second water pipes 206 to the four cross-shaped water pipes 207. The spray liquid is then transported to each of the rotating nozzles 208 through the four cross-shaped water pipes 207. Finally, the spray liquid is sprayed out through each of the rotating nozzles 208. The rotation of the rotating nozzles 208 makes the coverage of the spray liquid more uniform. The spray liquid and the exhaust gas are purified through gas-liquid contact. The purified gas is discharged through the air outlet 211, and the used spray liquid falls to the bottom of the spray tower 202.

[0033] like Figure 5 , Figure 6 and Figure 7As shown, the circulating filtration assembly 3 includes a second water pump 301 installed at the bottom of the spray tower 202. A third water pipe 302 is installed at the outlet of the second water pump 301. The outlet of the third water pipe 302 passes through the storage tank 203 and extends into the storage tank 203. A filter chamber 303 is installed around the third water pipe 302. A filter screen 304 is installed at one end of the filter chamber 303, and a filter element 305 is installed inside the filter chamber 303. A mixing tank 306 is welded to the top of the storage tank 203 for storing acidic and alkaline spray solutions. A cover 307 is hinged to the top of the mixing tank 306. A pH meter 308 is installed on one side of the storage tank 203. The probe 309 of the pH meter 308 passes through the storage tank 203. Extending into the storage tank 203, it is used to measure the pH value of the spray liquid. A PLC controller 310 is installed on one side of the storage tank 203, and a valve 311 is installed on one side of the mixing tank 306. There are two valves 311, which are installed symmetrically. During use, the used spray liquid is transported to the third water pipe 302 by the second water pump 301, and then preliminarily filtered by the filter screen 304. After further filtration by the filter screen 304, various impurities are removed, and finally it flows out into the storage tank 203. The pH value in the storage tank 203 is measured by the pH meter 308. When the pH value does not meet the requirements, a signal is transmitted to the PLC controller 310 to control the opening and closing of the two valves 311 in the mixing tank 306 to control the pH value of the spray liquid.

[0034] like Figure 3 and Figure 5 As shown, a bend 4 is welded to the top of the air outlet 211. A fan 5 is installed at one end of the bend 4, and an air outlet pipe 6 is welded to one end of the fan 5. An exhaust port 7 is welded to the top of the air outlet pipe 6.

[0035] like Figure 3 As shown, four steel columns 8 are welded to the top of the exhaust port 7. The top of the four steel columns 8 is welded with a rain cap 9, which can prevent rainwater from flowing through the exhaust port 7 to the bottom of the bend 4 and prevent the bend 4 from getting blocked.

[0036] like Figure 1 As shown, an observation hole 10 is welded on one side of the spray tower 202. There are three observation holes 10, and glass 11 is installed inside each of the three observation holes 10. During use, the internal condition of the spray tower 202 can be observed through the observation holes 10 to understand the usage status of the spray tower 202 in a timely manner.

[0037] like Figure 1 and Figure 5As shown, a circuit board 12 is installed at one end of both the air inlet 210 and the exhaust outlet 7. A gas quality sensor 13 is installed at one end of each circuit board 12, and a communication module 14 is installed at the end of each circuit board 12 away from the gas quality sensor 13. During use, the exhaust gas passing through the air inlet 210 is analyzed by the gas quality sensor 13, and the analysis is transmitted to the receiving device through the communication module 14. After the exhaust gas is purified, it is analyzed again by the gas quality sensor 13 when it passes through the exhaust outlet 7, and the analysis is transmitted to the receiving device through the communication module 14. The effect of exhaust gas purification is detected in real time.

[0038] like Figure 3 As shown, the spray tower 202, air inlet 210 and baffle plate 209 are made of fiberglass, which is corrosion resistant and lightweight. When in use, the fiberglass spray tower 202, air inlet 210 and baffle plate 209 can prevent the exhaust gas from corroding the equipment and improve the service life of the equipment.

[0039] Specifically, in use, this composite waste gas treatment spray tower works as follows: waste gas is introduced into the spray tower 202 through the inlet 210; the first water pump 204 draws spray liquid from the storage tank 203, transports it through the first water pipe 205 to four second water pipes 206, then from the four second water pipes 206 to four cross water pipes 207, and through the four cross water pipes 207 to each rotating nozzle 208; finally, the spray liquid is sprayed out through each rotating nozzle 208, and the rotation of the rotating nozzles 208 makes the coverage of the spray liquid more uniform. The spray liquid and waste gas are purified through gas-liquid contact. The purified gas is discharged through the outlet 211, and the used spray liquid falls to the bottom of the spray tower 202. (e.g.) Figure 3 , Figure 4 and Figure 6 As shown), the used spray liquid is transported to the third water pipe 302 by the second water pump 301, and then undergoes preliminary filtration through the filter screen 304. It is then further filtered through the filter screen 304 to remove various impurities, and finally flows into the storage tank 203. The pH value in the storage tank 203 is measured by the pH meter 308. When the pH value does not meet the requirements, a signal is transmitted to the PLC controller 310, which controls the opening and closing of the two valves 311 in the mixing tank 306 to control the pH value of the spray liquid (e.g., ...). Figure 5 , Figure 6 and Figure 7 (As shown).
