Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification and treatment, in particular to a spray tower for photocatalytic oxidation and coordinated waste gas treatment. Background Art

[0002] The spray tower for photocatalytic oxidation synergistic waste gas treatment is a waste gas treatment equipment that integrates photocatalytic oxidation technology and spray tower technology. This equipment combines the advantages of the two technologies and can more effectively treat industrial organic waste gas and convert it into non-toxic and harmless substances. This treatment method does not leave any secondary pollution, and can completely decompose organic pollutants and nitrogen oxides, converting them into harmless substances, which can effectively improve environmental quality and protect human health.

[0003] In the prior art, a Chinese patent document with publication number CN215585986U proposes a spray tower for photocatalytic oxidation synergistic treatment of waste gas. Under the synergistic effect of the packing structure, photocatalyst, ultraviolet rays and spray liquid, a part of the soluble substances in the flue gas is fully contacted with the spray liquid in gas-liquid phases and chemically reacted to be removed; at the same time, when the photocatalyst is irradiated with high-energy ultraviolet rays with energy greater than or equal to its energy gap, it will decompose and oxidize to remove nitrogen oxides and organic pollutants in the flue gas, thereby achieving the purpose of purifying the flue gas. However, the above patent document is consistent with the prior art in that different numbers of exhaust gas are not set according to the exhaust gas intake flow rate. The component of the exhaust pipe results in that when the exhaust gas intake flow rate is slow, the gas discharged from the exhaust pipe is also slow, which reduces the work efficiency. When the exhaust gas intake flow rate is fast, the gas discharged from the exhaust pipe is also fast, which makes it impossible for the exhaust gas to fully contact and react with the spray liquid, thereby reducing the purification treatment effect. Furthermore, we disclose a spray tower for photocatalytic oxidation synergistic treatment of exhaust gas to meet the actual needs that traditional spray towers for photocatalytic oxidation synergistic treatment of exhaust gas are not equipped with different numbers of exhaust pipe components according to the exhaust gas intake flow rate, resulting in lower work efficiency or poor purification effect due to different exhaust pipe flow rates during actual use.

[0015] Beneficial effects of the utility model:

[0016] The spray tower for the coordinated treatment of waste gas by photocatalytic oxidation is provided with a waste gas exhaust flow rate control component at the air inlet pipe. When the waste gas is discharged from the upper manifold through the air inlet pipe, different thrusts are generated according to the different flow rates of the waste gas. The faster the flow rate, the greater the thrust, causing the piston to slide inside the air inlet pipe, so that the position of the piston inside the air inlet pipe is different for different flow rates. When the flow rate is large, the thrust generated causes the plug to move to one side, thereby opening the flow outlets of the manifolds at different positions. When the flow rate slows down, the thrust of the telescopic spring will move the plug to the other side, closing the flow outlets of some manifolds. Through this structural design, the spray tower can control the exhaust gas discharge flow rate on the manifold according to the different flow rates of the waste gas in the air inlet pipe, so that the waste gas can maintain a uniform flow rate when discharged from the manifold, so that the waste gas can fully contact and react with the spray liquid to improve the purification treatment effect.

[0017] The spray tower is powered by a servo motor to rotate the fan, and the rotation of the fan drives the exhaust gas to rise to complete the gradual purification treatment. In addition, an internal exhaust gas stirring structure is arranged at the lower end of the fan, and the stirring structure is composed of a stirring rod, which is fixedly connected to the lower end of the fan. The stirring rod is driven to rotate by the rotation of the fan, and the fan-shaped connecting rod outside the stirring rod can disrupt the internal airflow, so that the exhaust gas forms a vortex or reflux in the tower, increasing the contact time and area between the exhaust gas and the spray liquid to achieve the best exhaust gas treatment effect.
