Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment, in particular to an environmentally friendly waste gas treatment device. Background Art

[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life, especially from chemical plants, steel mills, pharmaceutical plants, coking plants and refineries. The waste gas emitted has a strong odor, seriously polluting the environment and affecting human health. Waste gas purification mainly refers to the treatment of industrial waste gases such as dust particles, flue gas, odorous gases, and toxic and harmful gases generated in industrial places. Common waste gas purification includes factory smoke waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, chemical waste gas purification, etc.

[0003] When treating waste gas, the existing waste gas treatment device usually uses liquid medicine to react and neutralize the waste gas. However, the waste gas stays in the liquid medicine for a short time, resulting in incomplete reaction.

[0004] The prior art (application number: CN 214683336 U) discloses an exhaust gas treatment device, comprising a reaction tank, wherein a reaction liquid is contained in the reaction tank, an air inlet pipe and an air outlet pipe are connected to the reaction tank, the air outlet of the air inlet pipe is arranged below the liquid level of the reaction liquid, the air inlet of the air outlet pipe is arranged above the liquid level of the reaction liquid, a discharge port is arranged at the bottom of the reaction tank, a first valve is arranged on the discharge port, a liquid inlet is arranged on the reaction tank, a second valve is arranged on the liquid inlet, and a vibration motor is fixedly installed on the outer bottom of the reaction tank;

[0005] Although the above patent effectively avoids sludge enrichment and clings to the inner wall of the reaction tank, thereby improving the cleaning efficiency of the reaction tank, it has the following disadvantages. When in use, the waste gas stays in the reaction liquid for a short time, resulting in the waste gas staying in the potion for a short time, resulting in incomplete reaction and affecting the purification effect. Further improvement is needed. For this reason, we propose an environmentally friendly waste gas treatment device. Utility Model Content

[0006] The main purpose of the utility model is to provide an environmentally friendly waste gas treatment device, which can effectively solve the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] An environmentally friendly waste gas treatment device comprises a reaction tank, wherein a liquid inlet valve pipe is inserted and connected to the left upper end of the reaction tank, a filtering component is provided at the upper right upper end of the outer cylindrical surface of the reaction tank, a one-way valve is inserted and connected to the lower left outer cylindrical surface of the reaction tank, a cooling component is connected to the upper end of the one-way valve, a spiral blade is provided in the reaction tank, a horizontal plate is installed at the lower right outer surface of the reaction tank, a diaphragm pump is installed at the upper end of the horizontal plate, and a connecting pipe is connected to the suction end of the diaphragm pump.

[0009] Preferably, the cooling component comprises a cooling pipe, the outer surface of the cooling pipe is interspersed with two cooling valve pipes distributed up and down, the upper end of the cooling pipe is interspersed with an air intake pipe, and a spiral pipe is arranged inside the cooling pipe.

[0010] Preferably, the filtering component includes a first air pipe, which is inserted and connected to the upper part of the outer cylindrical surface of the reaction tank, and the outer surface of the first air pipe is sleeved with a filter box, and the right end of the filter box is inserted and connected with a second air pipe, and the first filter screen and the second filter screen are arranged in sequence from left to right inside the filter box, and the filter box is fixedly connected to the reaction tank through a connecting plate.

[0011] Preferably, the exhaust end of the diaphragm pump extends into the reaction tank, and the end of the connecting pipe away from the reaction tank extends into the reaction tank.

[0012] Preferably, the upper end and the lower end of the spiral tube are connected to the air inlet pipe and the one-way valve respectively.

[0013] Preferably, a drain valve pipe is inserted and connected to the lower end of the reaction tank.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The spiral blades can extend the time that the waste gas stays in the reaction tank. When the waste gas enters the reaction tank, the spiral blades enable the waste gas to bend and rise, increasing the residence time, so that the waste gas and the medicine can fully react, making the reaction more thorough and ensuring the treatment effect;

[0016] 2. The temperature of the exhaust gas can be lowered by cooling components. When in use, cool water is passed through the cooling valve pipe on the lower side, and the cooling valve pipe on the upper side is opened. When the exhaust gas enters the spiral tube, the cold water can take away the temperature of the exhaust gas. Lowering the exhaust gas temperature can slow down the diffusion rate of the exhaust gas molecules in the potion, prolonging the time they stay in the potion, which helps the exhaust gas to contact and react with the reaction liquid more fully, thereby improving the reaction efficiency and product quality;

[0017] 3. The diaphragm pump can transport the waste gas at the top of the reaction tank back to the bottom of the reaction tank through the connecting pipe, further extending the time the waste gas stays in the reaction tank. BRIEF DESCRIPTION OF THE DRAWINGS
