[0002] Exhaust gas contains many pollutants, such as particulate matter and VOCs. If it is directly emitted into the atmosphere, it will pollute the environment. Therefore, the exhaust gas needs to be purified and treated. However, the existing exhaust gas spraying system wastes a lot of water resources during use.

[0003] A patent with publication number CN109985477B discloses a waste gas spray purification treatment device, including a purification pipe. The purification pipe is arranged from bottom to top with several spray rings, an adsorption layer, a hydrophobic and breathable membrane, a water layer and a sponge layer. In the process of use, the waste gas is first sprayed, and then fully purified by adsorption and water layer. The sprayed water can be recycled and reused, saving water resources.

[0004] In current technologies, when existing waste gas is sprayed for purification, the liquid density is insufficient, resulting in insufficient contact area and range between the waste gas and the liquid. Consequently, some impurity particles cannot be effectively purified during the waste gas purification process.

[0005] Therefore, a waste gas treatment spray device is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the above-mentioned problems, a waste gas treatment spray device is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The waste gas treatment spray device of this utility model includes a foundation plate and multiple sets of spray tanks fixedly installed on the outer surface of the top of the foundation plate. A drain pipe is fixedly connected to the receiving end of the outer surface of the multiple sets of spray tanks. An exhaust pipe is fixedly installed on the output end of the spray tank. An inner liner is provided on the inner wall of the spray tank. A solution cylinder is provided at the inner center of the spray tank and at the inner edge of the inner liner. An air inlet pipe is fixedly installed at the bottom edge of one side of the spray tank, and one end of the air inlet pipe extends to the inner wall of the inner liner. A motor is fixedly installed on the top surface of the spray tank and at the center. A filter plate is provided between the outer surface of the solution cylinder and the inner wall of the inner liner.

[0008] Preferably, two sets of solution tanks are fixedly installed on the top surface of the spray tank, and a liquid extraction pipe is fixedly connected to the output end of the two sets of solution tanks.

[0009] Preferably, one end of the liquid extraction pipe extends through the spray tank to the inner wall of the solution cylinder, and a return pipe is fixedly connected to the outer surface of the solution cylinder.

[0010] Preferably, the return pipe is positioned on the inner wall of the solution cylinder, and the other end of the return pipe extends through the spray tank to the top edge.

[0011] Preferably, a cavity is provided between the spray tank and the inner liner, the output end of the motor extends to the inner wall of the solution cylinder, and a stirring and mixing plate is fixedly connected to the output end of the motor.

[0012] Preferably, multiple water spray strips are fixedly connected to the outer surface of the solution cylinder and at the top edge position, and the other end of the liquid extraction pipe passes through the solution cylinder and is fixedly connected to the inner wall of the multiple water spray strips.

Two sets of water guide pipes are fixedly installed on the receiving end of the cooling box, and the other end of the water guide pipes extends through the spray tank to the inner wall of the cavity.

[0015] The beneficial effects of this utility model are:

[0016] This utility model provides a waste gas treatment spray device. With the help of an air inlet pipe, waste gas is pumped into the interior of the inner tank. The angle of the air inlet pipe, combined with the inclination of the inlet pipe, allows the waste gas to follow the curvature of the inner wall of the tank, causing the waste gas carrying the spray liquid to rotate on the inner wall. This creates a vortex-like rotation of the spray liquid on the inner wall, increasing the contact time and force between the waste gas and the spray liquid. The rotation of the liquid generates significant centrifugal force. Based on the centrifugal force and fluid dynamics effects, gravity also acts on the impurity particles. Since gravity always points towards the bottom of the container, the impurity particles gradually settle under the combined action of centrifugal force and gravity.

[0017] This utility model provides a waste gas treatment spray device. As the gas increases on the inner wall of the inner tank, the bubbles will gradually rise inside the spray liquid and pass through the filter plate. When the waste gas passes through the filter plate, some fine particulate impurities can be filtered out. The driving force of the vortex liquid on the inner wall of the inner tank is used to scrape off some impurity particles that are attached to the bottom surface of the filter plate. Under the combined action of centrifugal force and gravity, the filtered impurity particles are effectively scraped and cleaned. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figure 1 - Figure 5This utility model provides a waste gas treatment spray device, including a foundation plate 11 and multiple spray tanks 12 fixedly installed on the outer surface of the top of the foundation plate 11. A drain pipe 13 is fixedly connected to the receiving end of the outer surface of the multiple spray tanks 12, and an exhaust pipe 14 is fixedly installed on the output end of the spray tank 12. An inner liner 124 is provided on the inner wall of the spray tank 12. A solution cylinder 126 is provided at the inner center of the spray tank 12 and at the inner edge of the inner liner 124. An air inlet pipe 128 is fixedly installed at the bottom edge of one side of the spray tank 12, and one end of the air inlet pipe 128 extends to the inner wall of the inner liner 124. A motor 122 is fixedly installed on the top surface of the spray tank 12 and at the center. A filter plate 127 is provided between the outer surface of the solution cylinder 126 and the inner wall of the inner liner 124.

[0028] During operation, two sets of solution tanks 121 respectively pour clean water and spray liquid into the solution cylinder 126. At the same time, the motor 122 rotates the stirring and mixing plate 123, ensuring that the spray liquid and clean water inside the solution cylinder 126 are fully mixed. Meanwhile, the air inlet pipe 128 pours exhaust gas into the inner liner 124. The inclination angle of the air inlet pipe 128 ensures that the exhaust gas follows the curvature of the inner wall of the inner liner 124 as it is poured into the inner liner 124. The exhaust gas carrying the spray liquid rotates on the inner wall of the inner liner 124, causing the spray liquid to rotate in a vortex shape on the inner wall of the inner liner 124. This increases the contact time and contact force between the exhaust gas and the spray liquid. The liquid generates a large centrifugal force when rotating. Based on the centrifugal force and fluid dynamics effect, gravity also acts on the impurity particles. Since gravity always points to the bottom of the container, the impurity particles gradually settle down under the combined action of centrifugal force and gravity.

[0029] Furthermore, such as Figures 1 to 5 As shown, two sets of solution tanks 121 are fixedly installed on the top surface of the spray tank 12. A liquid extraction pipe a2 is fixedly connected to the output end of the two sets of solution tanks 121. One end of the liquid extraction pipe a2 passes through the spray tank 12 and extends to the inner wall of the solution cylinder 126. A return pipe a3 is fixedly connected to the outer surface of the solution cylinder 126. The return pipe a3 is located on the inner wall of the solution cylinder 126. The other end of the return pipe a3 passes through the spray tank 12 and extends to the top edge.

[0030] During operation, as the gas increases on the inner wall of the inner liner 124, the bubbles gradually rise inside the spray liquid and pass through the filter plate 127. When the exhaust gas passes through the filter plate 127, some fine particulate impurities can be filtered out. The driving force of the vortex liquid on the inner wall of the inner liner 124 is used to scrape off some impurity particles that adhere to the bottom surface of the filter plate 127. Under the combined action of centrifugal force and gravity, the filtered impurity particles are effectively scraped and cleaned.

[0031] After the exhaust gas passes through the filter plate 127, it will gradually separate from the spray liquid. At this time, the pure spray liquid deep inside the solution cylinder 126 is absorbed by the suction pipe a2, and the pure spray liquid is sprayed out through multiple water spray strips a1 at one end of the suction pipe a2. This allows the pure spray liquid to have secondary contact and mixing purification treatment with the filtered exhaust gas. The contaminated spray liquid inside the inner tank 124 is absorbed by the return pipe a3, and the contaminated spray liquid is absorbed and discharged, so that the spray liquid inside the inner tank 124 can always maintain the effect of a specific purity liquid.

[0032] Furthermore, such as Figures 1 to 5 As shown, a cavity 125 is provided between the spray tank 12 and the inner liner 124. The output end of the motor 122 extends to the inner wall of the solution cylinder 126. A stirring and mixing plate 123 is fixedly connected to the output end of the motor 122. Multiple water spray strips a1 are fixedly connected to the outer surface of the solution cylinder 126 at the top edge. The other end of the liquid extraction pipe a2 passes through the solution cylinder 126 and is fixedly connected to the inner wall of the multiple water spray strips a1. An exhaust pipe 129 is fixedly connected to the inner wall of the inner liner 124, and the other end of the exhaust pipe 129 is fixedly connected to one end of the exhaust pipe 14. A cooling box 111 is fixedly connected to the top surface of the foundation plate 11 at one edge. Two sets of guide water pipes 112 are fixedly installed on the receiving end of the cooling box 111. The other end of the guide water pipes 112 passes through the spray tank 12 and extends to the inner wall of the cavity 125.

[0033] During operation, multiple spray tanks 12 are used to repeatedly purify the exhaust gas. After the exhaust gas is purified, it is diverted out through the exhaust pipe 14. While the exhaust gas is being purified, the cooling box 111 fills the guide water pipe 112 with positioning liquid. At this time, the curvature of the inner wall of the cavity 125 causes the guide water pipe 112 to rotate and rise inside the cavity 125 when spraying the low-temperature liquid. The rapid flow of water keeps the outer surface of the inner liner 124 at a low temperature. The low-temperature liquid gradually rises from the bottom of the cavity 125. During the rising process, the low-temperature liquid absorbs a large amount of heat from the inner liner 124, thereby reducing the pressure inside the inner liner 124. After absorbing the heat, the liquid, along with another guide water pipe 112, absorbs the heat from the top of the spray tank 12 and enters the cooling box 111, achieving a secondary cooling effect on the heat source.

[0034] Working principle: The exhaust gas is pumped into the inner liner 124 through the intake pipe 128. The inclination angle of the intake pipe 128 allows the exhaust gas to follow the curvature of the inner wall of the inner liner 124 as it is pumped in. This causes the exhaust gas to carry the spray liquid and rotate on the inner wall of the inner liner 124, resulting in a vortex-like rotation of the spray liquid. This increases the contact time and contact force between the exhaust gas and the spray liquid. The rotation of the liquid generates a large centrifugal force. Based on the centrifugal force and fluid dynamics, gravity also acts on the impurity particles. Since gravity always points to the bottom of the container, the impurity particles gradually settle down under the combined action of centrifugal force and gravity.

[0035] As the gas increases on the inner wall of the inner liner 124, the bubbles will gradually rise inside the spray liquid and pass through the filter plate 127. When the exhaust gas passes through the filter plate 127, some fine particulate impurities can be filtered out. The driving force of the vortex liquid on the inner wall of the inner liner 124 will scrape off some impurity particles adhering to the bottom surface of the filter plate 127. Under the combined action of centrifugal force and gravity, the filtered impurity particles are scraped and cleaned.

[0036] After the exhaust gas passes through the filter plate 127, the exhaust gas will gradually separate from the spray liquid. At this time, the pure spray liquid deep inside the solution cylinder 126 is absorbed by the liquid extraction pipe a2, and the pure spray liquid is sprayed out through multiple water spray strips a1 at one end of the liquid extraction pipe a2, so that the pure spray liquid and the filtered exhaust gas can be contacted and mixed for purification. The contaminated spray liquid inside the inner tank 124 is absorbed by the return pipe a3, and the contaminated spray liquid is absorbed and discharged, so that the spray liquid inside the inner tank 124 can always maintain the effect of a specific purity liquid.

[0037] Multiple spray tanks 12 are used to repeatedly purify the exhaust gas. After the exhaust gas is purified, it is diverted out through the exhaust pipe 14. During the purification process, the cooling box 111 fills the guide water pipe 112 with positioning liquid. The curvature of the inner wall of the cavity 125 causes the guide water pipe 112 to rotate and rise inside the cavity 125 when spraying the low-temperature liquid. The rapid flow of water keeps the outer surface of the inner liner 124 at a low temperature. The low-temperature liquid rises gradually from the bottom of the cavity 125. During the rise, the low-temperature liquid absorbs a large amount of heat from the inner liner 124, thereby reducing the pressure inside the inner liner 124. After absorbing the heat, the liquid, along with another guide water pipe 112, absorbs the heat from the top of the spray tank 12 and enters the cooling box 111, achieving a secondary cooling effect on the heat source.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
