Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] Example
[0029] Reference Figures 1-4This utility model provides a technical solution: a combined waste gas purification device, including a housing 1 and a waste gas purification mechanism 3, with a flat filter plate 2 installed inside the housing 1. The waste gas purification mechanism 3 includes a spray pipe 31, which is installed inside the housing 1 and arranged side by side. One end of the spray pipe 31 is also connected to a hollow chamber 311. A triangular filter plate 32 is installed at the bottom of the housing 1, and a liquid outlet hole 321 is provided on the outer surface of the triangular filter plate 32. A first liquid collection tank 33 is located outside the housing 1, and an inlet pipe 331 is installed on the first liquid collection tank 33. One end of the inlet pipe 331 extends into the interior of the housing 1 and is located inside the triangular filter plate 32.
[0030] By installing a flat filter plate 2 inside the housing 1 and a triangular filter plate 32 below the flat filter plate 2, when the exhaust gas enters the housing 1, the treatment liquid can be sprayed out through the spray pipe 31 to treat the exhaust gas. The particles in the exhaust gas will mix with water droplets and fall freely onto the flat filter plate 2 and the triangular filter plate 32, where the particles are treated, thus avoiding secondary pollution when the liquid is recycled.
[0031] In a preferred embodiment, an air inlet pipe 4 is fixedly installed on the outer side of the housing 1, and a control valve is provided on the air inlet pipe 4. One end of the air inlet pipe 4 extends into the interior of the housing 1 and communicates with the interior of the housing 1 to transport exhaust gas into the interior of the housing 1. Support legs are stably installed at the bottom of the housing 1. This device has an air inlet pipe 4 installed on the outside of the housing 1, and the air inlet pipe 4 communicates with the interior of the housing 1. In actual use, the collected exhaust gas is transported into the interior of the air inlet pipe 4. The exhaust gas can directly enter the interior of the housing 1 through the interior of the air inlet pipe 4, thereby purifying the exhaust gas.
[0032] In a preferred embodiment, the flat filter plate 2 is stably installed inside the housing 1 and positioned below the air inlet pipe 4. The flat filter plate 2 is also positioned above the triangular filter plate 32. Several triangular filter plates 32 are arranged side by side and connected together. A baffle 5 is provided on the outside of the triangular filter plate 32 and is integrated with the triangular filter plate 32. The position of the flat filter plate 2 allows the exhaust gas to enter the housing 1 and rise without obstruction. Positioning the flat filter plate 2 below the triangular filter plate 32 allows for particle treatment from both sides, ensuring that the recovered liquid is free of particles.
[0033] This device uses a spray method to treat waste gas. A positioning plate 6 is fixedly installed on the outer surface of the housing 1. A second liquid collection tank 7 is fixed on the upper surface of the positioning plate 6, and a liquid pump 8 is stably installed on the upper surface of the positioning plate 6. The liquid pump 8 has a circular pipe 9 installed at its inlet and outlet ends. The circular pipe 9 at the outlet end of the liquid pump 8 is connected to the inside of the hollow chamber 311. In actual use, the liquid pump 8 should be turned on before the waste gas enters the housing 1. The liquid pump 8 extracts the liquid from the second liquid collection tank 7 and transports it to the inside of the spray pipe 31. The spray pipe 31 is equipped with an outlet pipe with several small holes, so that the sprayed liquid is in the form of a mist. The mist can expand the spray area and improve the treatment effect of the waste gas.
[0034] Industrial waste gas contains ozone, which causes an unpleasant odor. Therefore, ozone removal is necessary during waste gas treatment. An ozone removal mechanism 10 is installed inside the housing 1. This mechanism includes activated carbon 101, an air inlet 102, and a delivery pipe 103. A fixing plate 11 is fixedly installed inside the housing 1, and the air inlet 102 passes through the fixing plate 11 for positioning. The delivery pipe 103 is located at the top of the air inlet 102, and the air inlet 102 and delivery pipe 103 are integrated. The delivery pipe 103 is bent inside the housing 1, with one end extending out of the housing 1. A heating plate 12 is fixedly installed on the upper surface of the fixing plate 11, contacting the outer surface of the delivery pipe 103 for heating it.
[0035] In practical use, activated carbon 101 can absorb ozone in waste gas and remove odors. Since the absorption capacity of activated carbon 101 becomes poor after a period of use, in order to completely remove ozone, a conveying pipe 103 is set above activated carbon 101. Gas passes through activated carbon 101 and moves to the bottom of fixed plate 11. When lifted, it enters the air inlet cylinder 102 and is conveyed to the conveying pipe 103. At the same time, heating plate 12 is turned on to heat the conveying pipe 103, so that the inside of the conveying pipe 103 is in a high-temperature state. When gas passes through the air inlet cylinder 102, it directly enters the conveying pipe 103. Ozone will be reduced to oxygen when the temperature exceeds 55℃, which can remove ozone and improve the purification effect of waste gas.
[0036] Specifically, the working process or working principle of a combined waste gas purification device is as follows: Currently, most waste gas treatment methods use equipment, such as waste gas adsorption and disinfection. However, in existing operations, waste gas is sprayed, and because the waste gas contains a lot of dust and impurities, the water after spraying is also mixed with dust and impurities. If this water is recycled again, it will cause secondary pollution. Therefore, this device was designed to solve this problem.
[0037] This device can treat sprayed liquid. When the sprayed liquid comes into contact with particles in the exhaust gas, the particles will mix with the liquid and fall together. The particles and liquid are separated by the flat filter plate 2 and the triangular filter plate 32, which avoids secondary pollution when the liquid is reused. The specific operation is as follows: before using this device, it is connected to an external power source. The exhaust gas is transported into the interior of the air inlet pipe 4, and then the exhaust gas is transported into the interior of the housing 1 through the air inlet pipe 4. Before the air is inlet, the liquid pump 8 is turned on. The liquid pump 8 can extract the sprayed liquid from the second liquid collection tank 7 and transport it into the interior of the spray pipe 31. The liquid is sprayed out in the form of a mist. In order to ensure the spraying effect of the liquid on the gas, this device is set with several spray pipes 31. Each spray pipe 31 sprays the misted liquid in a cone shape. The liquid sprayed from several spray pipes 31 is staggered and covers the entire interior of the housing 1, which can ensure the spraying effect on the exhaust gas.
[0038] Because the exhaust gas contains particulate impurities, these impurities condense into water droplets upon contact with the liquid as the gas rises. These droplets then fall under their own weight onto the flat filter plate 2, where they are filtered. The liquid passes through the flat filter plate 2, leaving the particles on it. To improve efficiency, a triangular filter plate 32 is installed at the bottom of the flat filter plate 2. Larger particles remain on the flat filter plate 2, while smaller particles pass through and fall onto the triangular filter plate 32. The triangular filter plate 32 has several vertically arranged outlet holes 321. Particles slide down the inclined surface of the triangular filter plate 32 to the concave position, while liquid flows directly from the outlet holes 321 and falls directly to the bottom of the housing 1. When a large amount of liquid accumulates inside the housing 1, it can enter the first collection tank 33 through the inlet pipe 331 for liquid recovery. After the exhaust gas treatment is completed, the liquid is discharged, allowing for either continued use or discontinuation of the system.
[0039] The exhaust gas is continuously transported into the housing 1 and rises, causing it to move to the position of activated carbon 101. Activated carbon 101 can absorb ozone in the exhaust gas and remove odors. Since the absorption capacity of activated carbon 101 becomes poor after a period of use, a conveying pipe 103 is installed above activated carbon 101 to completely remove ozone. The gas passes through activated carbon 101 and moves to the bottom of fixed plate 11. When lifted, it enters the air inlet cylinder 102 and is then transported to the conveying pipe 103. At the same time, heating plate 12 is turned on to heat the conveying pipe 103, making the inside of the conveying pipe 103 a high temperature. When the gas passes through the air inlet cylinder 102, it directly enters the conveying pipe 103. Ozone will be reduced to oxygen when the temperature exceeds 55°C, thus removing ozone. The removed gas can then be transported to the next process.
