Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically an automatic circulation tank for waste gas treatment. Background Technology

[0002] Existing automatic circulating tank equipment for waste gas treatment often employs a combination of multiple processes to improve treatment efficiency. For example, utility model patent publication number 03N213556194U discloses an automatic circulating tank for waste gas treatment that integrates adsorption, UV photolysis, and spray washing into a single unit. However, this design has the following drawbacks: It places the UV photolysis module before the spray washing module, allowing untreated waste gas containing a large amount of particulate matter and water vapor to directly pass through the UV lamps. This results in rapid contamination and scaling on the lamp surface, a sharp decrease in UV light intensity, and low or even complete failure of photolysis efficiency. Furthermore, its internal structure is complex; core maintenance components such as the adsorption plates and UV lamps are all installed inside the unit. Replacement and cleaning require opening the unit and accessing the interior, making maintenance extremely inconvenient, resulting in long downtimes and high operating costs.

[0003] In view of this, we propose an automatic circulation tank for waste gas treatment. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic circulating tank for waste gas treatment to solve the problems mentioned in the background art.

[0005] An automatic circulating tank for waste gas treatment includes a tower body, which, from bottom to top, is provided with a washing and circulation section, a gas-liquid separation and preliminary treatment section, a UV photolysis oxidation section, and a final adsorption protection section; the UV photolysis oxidation section includes several drawer-type UV photolysis modules that can be directly extracted from the outside of the tower body; the final adsorption protection section includes several drawer-type activated carbon adsorption modules that can be directly extracted from the outside of the tower body; the bottom side wall of the tower body is provided with a waste gas inlet, and the top is provided with a purified gas outlet.

[0006] Preferably, the washing circulation section includes a circulating water tank located at the bottom of the tower body, a water pump installed in the circulating water tank, and a spray pipeline system connected to the water pump and extending to the upper part of the tower body.

[0007] Preferably, the gas-liquid separation and preliminary treatment section is located above the washing circulation section and includes at least one demister and one dry filter layer for removing water mist and particulate matter from the gas.

[0008] Preferably, the drawer-type UV photolysis module includes a sealed metal frame, several UV lamps and a catalytic mesh disposed within the frame, and the frame is provided with a handle and a quick electrical interface for connection to the tower body.

[0009] Preferably, both the drawer-type UV photolysis module and the drawer-type activated carbon adsorption module are provided with sealing strips at their mounting ports. The sealing strips are specifically corrosion-resistant and aging-resistant silicone rubber sealing strips to ensure airtightness when they are in the closed state.

[0010] Preferably, the spray pipeline system includes several spray layers, each spray layer is evenly distributed with spiral solid cone nozzles to ensure that there are no dead corners in the spray coverage.

[0011] Preferably, the circulating water tank is connected to an automatic drain valve and an automatic water replenishment valve, and can be linked to the dosing system via a pH sensor to maintain the optimal chemical state of the washing liquid.

[0012] Beneficial effects

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The process adopts "washing first, then defogging and dust removal, then photolysis, and finally adsorption". The washing layer removes most of the soluble pollutants and particulate matter, and the defogging filter layer ensures that the gas entering the UV photolysis section is dry and clean, avoiding contamination and scaling of the UV lamp tube, ensuring the radiation intensity and processing efficiency of the ultraviolet light, and enabling the UV photolysis to function effectively.

[0015] 2. The UV lamps and activated carbon, which require the most regular replacement and maintenance, are designed as standardized drawer-type modules. Maintenance personnel can quickly replace individual modules within minutes of shutdown without entering the tower or using any tools, reducing labor intensity, downtime, and maintenance costs.

[0016] 3. The scientific process avoids contact between moisture and electrical components, reducing the risk of short circuits and lamp explosions. The modular design also facilitates the maintenance of individual functional units without affecting the overall structural stability.

[0017] 4. It can be integrated with automatic sewage discharge, water replenishment and chemical dosing systems to achieve automatic control of the quality of the washing liquid and ensure the stability of the treatment effect. Attached Figure Description

[0025] Please see Figure 1-3 This utility model provides a technical solution:

[0026] An automatic circulating tank for waste gas treatment includes a tower body 1. From bottom to top, the tower body 1 is provided with a washing and circulating section, a gas-liquid separation and preliminary treatment section, a UV photolysis oxidation section, and a final adsorption support section. The UV photolysis oxidation section includes several drawer-type UV photolysis modules 8 that can be directly pulled out from the outside of the tower body 1. The final adsorption support section includes several drawer-type activated carbon adsorption modules 9 that can be directly pulled out from the outside of the tower body 1. The bottom side wall of the tower body 1 has a waste gas inlet 2, and the top has a purified gas outlet 10. The washing and circulating section includes a circulating water tank 3 located at the bottom of the tower body 1, a water pump 4 installed in the circulating water tank 3, and a spray pipe connected to the water pump 4 and extending to the upper part of the tower body 1. The system includes a gas-liquid separation and preliminary treatment section located above the washing and circulation section, comprising at least one demister 6 and one dry filter layer 7. The drawer-type UV photolysis module 8 includes a sealed metal frame, several UV lamps 802 and a catalytic mesh 803 disposed within the frame, and a handle 801 and a quick electrical interface 804 connected to the tower body 1 on the frame. Both the drawer-type UV photolysis module 8 and the drawer-type activated carbon adsorption module 9 have sealing strips at their mounting ports. The spray pipeline system includes several spray layers 5, each spray layer 5 having evenly distributed spiral solid cone nozzles. The outer wall of the circulating water tank 3 is fixedly connected to a pH sensor 301, an automatic drain valve 302, and an automatic water replenishment valve 303.

[0027] Understandably, the exhaust gas enters through the exhaust gas inlet 2 at the bottom of the tower body 1, and first comes into full contact with the washing liquid sprayed from the spray layer 5 in a reverse direction, where pollutants are absorbed and transferred to the liquid phase. The gas then passes upward through the demister 6 and the dry filter layer 7, removing water droplets and fine particles. The pretreated, dry, and clean gas enters the UV photolysis oxidation section, where the UV lamps 802 in the drawer-type UV photolysis module 8 emit high-energy ultraviolet light, working in synergy with the catalytic mesh 803 to break down and oxidize the molecular chains of odorous substances and VOO3s in the exhaust gas. Finally, the gas enters the final adsorption protection section, where the drawer-type activated carbon adsorption module 9 adsorbs residual trace pollutants and byproducts. The thoroughly purified gas is then discharged through the purified gas outlet 10 in compliance with standards. When it is necessary to replace the UV lamps or activated carbon, simply disconnect the power supply to the corresponding module, open the maintenance door on the side of the tower body, grasp the handle 801 to pull out the entire module, replace it with the pre-installed new module and push it in, and connect the quick-connect electrical interface 804. The entire process is safe, fast, and clean. When the pH sensor 301 detects an abnormality in the solution of the medicine in the circulating water tank 3, the automatic drain valve 302 will be opened automatically to drain the abnormal solution and then the solution will be replenished through the automatic water replenishment valve 303.
