Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an environmental protection equipment for waste gas treatment. Background Technique

[0002] Waste gas refers to the toxic and harmful gases discharged by humans in the process of production and life. For example, sulfur-containing waste gas will cause direct harm to people's living environment. This is because it can combine with water in the air to form acidic substances, triggering acid rain, and acid rain will damage plants, buildings and human health, especially affecting people's respiratory tract. In addition, it will also affect the soil and water sources, causing secondary pollution. Therefore, it is necessary to treat waste gas to ensure that the discharged waste gas will not cause harm to the human body.

[0003] For the existing environmental protection equipment for waste gas treatment, the treatment method for sulfur-containing waste gas is usually to spray an adsorbent through a nozzle to contact the sulfur-containing waste gas and desulfurize the waste gas, so that the waste gas meets the emission standard. However, when desulfurizing the waste gas in this way, the waste gas inside the waste gas treatment environmental protection equipment has too short residence time when rising, so that the adsorbent sprayed by the nozzle is difficult to be fully mixed with the waste gas, resulting in incomplete desulfurization of the waste gas and still having potential safety hazards after emission. Content of the Utility Model

[0004] Based on this, the purpose of the present utility model is to provide an environmental protection equipment for waste gas treatment to solve the technical problems mentioned in the above background technique.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: an environmental protection equipment for waste gas treatment, including a device main body, an installation box is connected to the top of the device main body, a rotating shaft penetrates through the bottom of the installation box, one end and the other end of the rotating shaft are respectively connected with an impeller and a dispersion plate, dispersion holes penetrate through the bottom of the dispersion plate, a fan blade is connected to the outer ring of the dispersion plate, a flow dividing plate is connected inside the device main body, exhaust holes penetrate through the flow dividing plate, and a liquid collecting tank is opened at the bottom of the device main body.

[0006] By adopting the above technical solution, when desulfurization of waste gas is required, first, the staff starts the water pump. The water pump sends the adsorbent in the liquid collection tank into the dispersion plate through the infusion pipe. Subsequently, the staff starts the blower to make the waste gas pass through the air inlet, the installation box, and the intake pipe in sequence, and finally enter the equipment main body. When the waste gas passes through the installation box, it blows the impeller to rotate. The impeller makes the dispersion plate and the fan blades rotate through the rotating shaft. When the dispersion plate rotates, the adsorbent is uniformly thrown out through the dispersion holes under the action of centrifugal force and enters the exhaust holes. At the same time, the waste gas rises into the exhaust holes and contacts the adsorbent for desulfurization work. Since the exhaust holes are serpentine, the flow path of the waste gas is extended, thereby increasing the contact time between the waste gas and the adsorbent. As the waste gas continues to rise, the fan blades rotate and then generate a slight wind force. The downward wind force and the upward waste gas form a convection, thereby delaying the flow rate of the waste gas again. Through these two steps, the waste gas can fully contact the adsorbent for desulfurization work, effectively removing the sulfide in the waste gas and making it difficult for the discharged waste gas to cause harm to human health.

[0007] Further, one side of the installation box is connected with an intake pipe, and the end of the intake pipe is communicated with the equipment main body. The other side of the installation box is penetrated by an intake pipe.

[0008] By adopting the above technical solution, the waste gas passes through the air inlet, the installation box, and the intake pipe in sequence, and finally enters the equipment main body for desulfurization work.

[0009] Further, a water pump is installed on one side of the equipment main body, and the output end of the water pump is connected with an infusion pipe.

[0010] By adopting the above technical solution, the staff starts the water pump, and the water pump pumps the adsorbent in the liquid collection tank into the dispersion plate through the infusion pipe.

[0011] Further, an exhaust port and support feet are respectively connected to the top and bottom of the equipment main body. A flow guiding block is connected inside the equipment main body, and the flow guiding block is in a slope shape.

[0012] By adopting the above technical solution, the desulfurized waste gas is discharged through the exhaust port. The equipment main body is placed on the ground through the support feet. The adsorbent remaining inside the exhaust holes drips downward onto the slope-shaped flow guiding block under the action of gravity and finally enters the liquid collection tank.

[0013] Further, there are multiple groups of exhaust holes, and all the multiple groups of exhaust holes are in a serpentine bending shape.

[0014] By adopting the above technical solution, since the exhaust holes are serpentine, the flow path of the waste gas is extended, thereby increasing the contact time between the waste gas and the adsorbent.

[0015] Further, a one-way valve is provided on the outer surface of the intake pipe.

[0016] By adopting the above technical solution, through the setting of the one-way valve, the reverse flow of waste gas out of the equipment main body under the blowing of the fan blades is avoided.

[0017] Furthermore, the bottom of the equipment main body is connected to the liquid collecting tank through a communication hole.

[0018] By adopting the above technical solution, the adsorbent remaining in the exhaust hole enters the liquid collecting tank again through the communication hole for recycling.

[0019] In summary, the main beneficial effects of the present utility model are as follows:

[0020] Through the settings of the impeller, dispersion plate, dispersion holes, fan blades and exhaust holes in the present utility model, when desulfurization of waste gas is required, first, the staff starts the water pump, and the water pump sends the adsorbent in the liquid collecting tank into the dispersion plate through the liquid delivery pipe. Subsequently, the staff starts the blower, and the waste gas passes through the air inlet, installation box and air inlet pipe in sequence, and finally enters the equipment main body. When the waste gas passes through the installation box, it blows the impeller to rotate. The impeller makes the dispersion plate and fan blades rotate through the rotating shaft. When the dispersion plate rotates, the adsorbent is evenly thrown out through the dispersion holes under the action of centrifugal force and enters the exhaust holes. At the same time, the waste gas rises and enters the exhaust holes to contact the adsorbent for desulfurization work. Since the exhaust holes are serpentine, the flow path of the waste gas is extended, thereby increasing the contact time between the waste gas and the adsorbent. As the waste gas continues to rise, the fan blades rotate and then generate a fine wind force. The downward wind force and the upward waste gas form a convection, thereby delaying the flow rate of the waste gas again. Through these two steps, the waste gas can fully contact the adsorbent for desulfurization work, effectively removing the sulfide in the waste gas and making it difficult for the discharged waste gas to cause harm to human health.

[0029] Refer to Figures 1 - 3 , in the above embodiment, an air inlet pipe 3 is connected to one side of the installation box 2, and the end of the air inlet pipe 3 is communicated with the device main body 1, the air inlet pipe 3 penetrates through the other side of the installation box 2, the waste gas sequentially passes through the air inlet 15, the installation box 2 and the air inlet pipe 3, and finally enters the device main body 1 for desulfurization work, a water pump 12 is installed on one side of the device main body 1, and the output end of the water pump 12 is connected to an infusion pipe 13, and the staff starts the water pump 12, and the water pump 12 pumps the adsorbent in the liquid collecting tank 11 into the dispersion plate 6 through the infusion pipe 13.

[0030] Refer to Figure 1 and Figure 4, in the above embodiment, an exhaust port 14 and support feet 16 are respectively connected to the top and bottom of the device main body 1. A flow guide block 17 is connected inside the device main body 1, and the flow guide block 17 is in a slope shape. The desulfurized waste gas is discharged through the exhaust port 14. The device main body 1 is placed on the ground through the support feet 16. The adsorbent remaining inside the exhaust holes 10 drips downward under the action of gravity onto the slope-shaped flow guide block 17 and finally enters the liquid collection tank 11. There are multiple groups of exhaust holes 10, and all the multiple groups of exhaust holes 10 are in a serpentine shape.

At the same time, the waste gas rises and enters the exhaust holes 10 to contact the adsorbent for desulfurization work. Since the exhaust holes 10 are in a serpentine shape, the flow path of the waste gas is extended, thereby increasing the contact time between the waste gas and the adsorbent. As the waste gas continues to rise, the fan blades 8 rotate to generate a fine wind force. The downward wind force and the upward waste gas form a convection, thereby delaying the flow rate of the waste gas again. Through these two steps, the waste gas can fully contact the adsorbent for desulfurization work, effectively removing the sulfide in the waste gas. Finally, the desulfurized waste gas is discharged through the exhaust port 14, and the adsorbent remaining inside the exhaust holes 10 drips downward under the action of gravity onto the flow guide block 17. Due to the slope-shaped setting of the flow guide block 17, the adsorbent flows into the liquid collection tank 11, achieving the effect of reusing the adsorbent.
