Description

Technical Field

[0001] This application relates to the field of PCB wastewater treatment technology, and in particular to a waste gas collection and treatment device for a PCB wastewater treatment plant. Background Technology

[0002] PCB wastewater treatment plants often release toxic and harmful gases into the air during their wastewater treatment processes, and these gases often have unpleasant odors. Traditional wastewater treatment methods only purify the liquid wastewater, leaving the emitted gases largely untreated or with ineffective treatment. Wastewater treatment plants generate large amounts of waste gas during operation, which, if left untreated, can significantly impact the surrounding environment and, in severe cases, cause public nuisance. Common waste gas treatment methods include physical methods such as water washing, condensation, adsorption, and electron beam irradiation; biological methods such as plant-based gas coverage, plant absorption, and plant decomposition; and chemical methods such as combustion, oxidation, and chemical adsorption.

[0003] PCB wastewater treatment requires exhaust gas collection and treatment devices for PCB wastewater treatment plants. However, existing technologies struggle to address the complex composition of exhaust gases generated during wastewater treatment plant operation using a single method. For example, acid washing alone can only degrade alkaline gases to a certain extent, but other components are difficult to treat, resulting in exhaust gases containing high concentrations of ammonia nitrogen and other organic pollutants. Traditional exhaust gas treatment methods are often inefficient and cannot meet increasingly stringent environmental requirements. Therefore, this paper proposes an exhaust gas collection and treatment device for PCB wastewater treatment plants to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a waste gas collection and treatment device for PCB wastewater treatment plants. This device boasts advantages such as high treatment efficiency and strong practicality, solving the problem that existing technologies struggle to treat complex waste gases generated during wastewater treatment plant operation using a single method. For example, acid washing can only degrade alkaline gases to a certain extent, but other components are difficult to treat, resulting in waste gas containing high concentrations of ammonia nitrogen and other organic pollutants. Traditional waste gas treatment methods are often inefficient and unable to meet increasingly stringent environmental protection requirements.

[0005] In summary, this application provides the following technical solution: a waste gas collection and treatment device for a PCB wastewater treatment station, comprising a waste gas treatment tower, an inlet pipe fixedly connected to the top of the waste gas treatment tower, a biological treatment device disposed on the right side of the waste gas treatment tower, an adsorption tower disposed on the right side of the biological treatment device, and a sealing cover detachably connected to the upper surface of the adsorption tower. The waste gas treatment tower is provided with a rotating spray mechanism extending into its interior, and the adsorption tower is provided with a rotating adsorption mechanism inside its interior.

[0006] The rotary spraying mechanism includes a storage tank located outside the waste gas treatment tower, an installation pipe fixedly installed on the inner wall of the waste gas treatment tower, a booster pump fixedly installed on the top of the storage tank, and a rotary nozzle structure located on the lower surface of the installation pipe.

[0007] The rotary adsorption mechanism includes a servo motor fixedly installed on the inner top wall of the sealed cover, a rotating shaft fixedly connected to the output shaft of the servo motor, a connecting frame fixedly connected to the outside of the rotating shaft, and an activated carbon filter plate fixedly connected to the inside of the connecting frame.

[0008] This application employs the aforementioned technical solution. A controller activates a fan, causing the intake pipe to collect and transport pollutant-laden waste gas to the interior of the waste gas treatment tower. The controller then activates a booster pump, drawing ammonia water from the storage tank into the installation pipe via an extraction and delivery pipe. The booster pump pressurizes the ammonia water, causing the nozzle to rotate via a bushing. This ammonia water pressurization and rotation of the nozzle evenly sprays the ammonia water into the waste gas, increasing the contact area and reaction time between the ammonia water and the waste gas, thereby improving removal efficiency and achieving ammonia nitrogen neutralization, resulting in high treatment efficiency. The controller also activates a servo motor to rotate a shaft, which in turn rotates the connecting frame and activated carbon filter plate, enabling continuous adsorption and desorption of organic pollutants, improving treatment efficiency and the utilization rate of the adsorption material. By combining spray reaction and adsorption purification technologies, this approach achieves highly efficient waste gas treatment while reducing equipment maintenance complexity and costs, demonstrating strong practicality.

[0009] Furthermore, an extraction pipe is fixedly connected between the input end of the booster pump and the storage tank, and a delivery pipe that penetrates the waste gas treatment tower and extends into the installation pipe is fixedly connected to the output end of the booster pump.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the booster pump is started by the controller, so that the extraction pipe and the delivery pipe draw ammonia water from inside the storage tank into the installation pipe.

[0011] Furthermore, the rotating nozzle structure includes a connecting pipe fixedly connected to the bottom of the mounting pipe, a bushing sleeve fitted to the bottom end of the connecting pipe, a three-way pipe rotatably connected to the outside of the bushing, and two nozzles fixedly connected to the bottom of the three-way pipe.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the pressurization effect of the booster pump causes the three-way pipe to drive the nozzle to rotate through the bushing.

[0013] Furthermore, the number of the rotating nozzle structures is several, and the structures are distributed in a ring shape on the lower surface of the mounting tube.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by setting up several of the aforementioned rotating nozzles, it helps to increase the contact area and reaction time between ammonia water and waste gas.

[0015] Furthermore, the rotating shaft is rotatably connected to the inside of the adsorption tower, and there are four connecting frames and four activated carbon filter plates.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the servo motor is started by the controller to drive the rotating shaft to rotate, so that the rotating shaft drives the connecting frame and the activated carbon filter plate to rotate.

[0017] Furthermore, the four connecting frames are arranged in a ring shape around the outside of the rotating shaft, and the outer diameter of the four connecting frames is adapted to the inner diameter of the adsorption tower.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the rotating shaft drives the connecting frame and the activated carbon filter plate to rotate, which enables continuous adsorption and desorption of organic pollutants.

[0019] Furthermore, a gas collection pipe is fixedly connected between the waste gas treatment tower and the biological treatment device, and a suction pipe is fixedly connected between the biological treatment device and the sealing cover.

[0020] The beneficial effect of adopting the above-mentioned further scheme is that by setting up a biological treatment device, it helps to absorb or degrade some organic gases.

[0021] Furthermore, the air intake pipe is provided with a conveying mechanism, which includes a mounting shell fixedly connected to the inside of the air intake pipe, and a fan extending into the outside of the mounting shell is rotatably mounted therein.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the fan is started by the controller, so that the exhaust gas containing pollutants is collected and transported to the interior of the exhaust gas treatment tower through the intake pipe.

[0023] Compared with the prior art, this application provides a waste gas collection and treatment device for a PCB wastewater treatment plant, which has the following beneficial effects:

[0024] 1. This waste gas collection and treatment device for PCB wastewater treatment plants starts the fan through the controller, which collects and transports the waste gas containing pollutants to the interior of the waste gas treatment tower through the inlet pipe. Then, the booster pump is started by the controller, which draws ammonia water from the storage tank into the installation pipe through the extraction pipe and the delivery pipe. Through the pressurization of the booster pump, the three-way pipe drives the nozzle to rotate through the bushing. The pressurized ammonia water causes the nozzle to rotate and spray ammonia water evenly into the waste gas, which helps to increase the contact area and reaction time between ammonia water and waste gas, thereby improving the removal efficiency, realizing the neutralization reaction of ammonia nitrogen, and achieving the advantage of high treatment efficiency.

[0025] 2. This waste gas collection and treatment device for PCB wastewater treatment plants uses a controller to start a servo motor that drives a rotating shaft to rotate. This rotating shaft causes the connecting frame and activated carbon filter plate to rotate, enabling continuous adsorption and desorption of organic pollutants. This improves treatment efficiency and the utilization rate of adsorption materials. By combining spray reaction and adsorption purification technologies, it can achieve efficient treatment of waste gas while reducing the complexity and cost of equipment maintenance, thus achieving the advantages of strong practicality.

A rotary spray mechanism extending into the exterior of the waste gas treatment tower 1 is provided, and a rotary adsorption mechanism is provided inside the adsorption tower 4. The rotary spray mechanism includes a storage tank 6 disposed outside the waste gas treatment tower 1, an installation pipe 8 fixedly installed on the inner wall of the waste gas treatment tower 1, a booster pump 7 fixedly installed on the top of the storage tank 6, and a rotary nozzle structure disposed on the lower surface of the installation pipe 8. The booster pump 7 is activated by a controller, causing the extraction pipe and the delivery pipe 13 to draw ammonia water from inside the storage tank 6 into the installation pipe 8.

[0034] The booster pump 7 has an extraction pipe fixedly connected to the storage tank 6 at its input end, and a delivery pipe 13 fixedly connected to the output end of the booster pump 7, which passes through the waste gas treatment tower 1 and extends into the installation pipe 8.

[0035] Specifically, an extraction pipe is fixedly connected between the input end of the booster pump 7 and the storage tank 6, and a delivery pipe 13 is fixedly connected to the output end of the booster pump 7, which penetrates the waste gas treatment tower 1 and extends into the installation pipe 8. Through the pressurization effect of the booster pump 7, the three-way pipe 11 drives the nozzle 12 to rotate through the bushing 10.

[0036] It should be noted that the rotary nozzle structure includes a connecting pipe 9 fixedly connected to the bottom of the mounting pipe 8. A bushing 10 is sleeved at the bottom end of the connecting pipe 9. A three-way pipe 11 is rotatably connected to the outside of the bushing 10. Two nozzles 12 are fixedly connected to the bottom of the three-way pipe 11. There are several rotary nozzle structures, which are distributed in a ring shape on the lower surface of the mounting pipe 8.

[0037] In addition, a conveying mechanism is provided inside the air inlet pipe 2. The conveying mechanism includes a mounting shell 14 fixedly connected to the inside of the air inlet pipe 2, and a fan 15 extending into the outside of the mounting shell 14 is rotatably mounted therein. A gas collection pipe 20 is fixedly connected between the exhaust gas treatment tower 1 and the biological treatment device 3, and a suction pipe 21 is fixedly connected between the biological treatment device 3 and the sealing cover 5.

[0038] Please see Figure 2 and Figure 4In this embodiment, the rotary adsorption mechanism includes a servo motor 16 fixedly mounted on the inner top wall of the sealing cover 5, a rotating shaft 17 fixedly connected to the output shaft of the servo motor 16, a connecting frame 18 fixedly connected to the outside of the rotating shaft 17, and an activated carbon filter plate 19 fixedly connected to the inside of the connecting frame 18. The servo motor 16 is started by the controller, driving the rotating shaft 17 to rotate, which in turn causes the connecting frame 18 and the activated carbon filter plate 19 to rotate. This allows for continuous adsorption and desorption of organic pollutants, improving treatment efficiency and the utilization rate of the adsorption material.

[0039] The rotating shaft 17 is rotatably connected to the inside of the adsorption tower 4, and there are four connecting frames 18 and four activated carbon filter plates 19.

[0040] Specifically, the four connecting frames 18 and the activated carbon filter plate 19 are arranged in a ring shape outside the rotating shaft 17, and the outer diameter of the four connecting frames 18 is adapted to the inner diameter of the adsorption tower 4.

[0041] The working principle of the above embodiments is as follows:

[0042] In operation, the wastewater treatment plant's waste gas-generating tank is sealed, and the waste gas is transported to the interior of the waste gas treatment tower 1 by a blower 15. The booster pump 7 is activated by the controller, causing the extraction pipe and delivery pipe 13 to draw ammonia water from the storage tank 6 into the installation pipe 8. The booster pump 7 pressurizes the ammonia water, causing the three-way pipe 11 to rotate via the bushing 10, thus rotating the nozzle 12. The pressurized ammonia water causes the nozzle 12 to evenly spray ammonia water into the waste gas, increasing the contact area and reaction time between the ammonia water and the waste gas, and preventing damage to subsequent equipment. The microorganisms and activated carbon in the container are adversely affected. After pretreatment, the waste gas enters the biological treatment device 3 to absorb or degrade some organic gases and enters the adsorption tower 4. The servo motor 16 is started by the controller to drive the rotating shaft 17 to rotate, so that the rotating shaft 17 drives the connecting frame 18 and the activated carbon filter plate 19 to rotate. It can continuously adsorb and desorb organic pollutants. After desorption, waste liquid or high-concentration tail gas can be discharged and reused multiple times. The treated waste gas can be directly passed into the wastewater of the sewage tank and re-enter the waste gas treatment device for treatment to meet the atmospheric emission standards.
