Technical Field

[0001] This utility model relates to the field of chemical tail gas treatment technology, specifically a chemical production tail gas neutralization treatment device. Background Technology

[0002] Chemical production exhaust gas refers to the toxic and harmful gases emitted by chemical plants during the chemical production process. These exhaust gases typically contain a variety of pollutants, including chlorine, hydrogen chloride, vinyl chloride, mercury, acetylene, nitrogen oxides, urea dust, carbon monoxide, ammonia, sulfur dioxide, and methane. The physical and chemical properties of these exhaust gases are complex, and their toxicity varies, seriously polluting the environment and affecting human health.

[0003] Conventional chemical enterprises typically use chemical production tail gas neutralization equipment that directly injects the tail gas into the neutralization tank and then sprays a neutralizing agent into the tank to neutralize the gas. However, uneven distribution of the tail gas inside the neutralization tank during treatment can affect the effectiveness of the neutralization process.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a chemical production tail gas neutralization treatment device. Utility Model Content

[0005] The purpose of this invention is to provide a chemical production tail gas neutralization and treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chemical production tail gas neutralization treatment device, comprising a neutralization tank and a turbulence shroud assembly. The surface of the neutralization tank is equipped with a spray structure, and the top of the neutralization tank is equipped with a top cover. The turbulence shroud assembly is installed through the middle of the top cover. The turbulence shroud assembly includes a servo motor, a drive gear, a stabilizer bar, fan blades, and driven gears. The bottom power output end of the servo motor is equipped with a drive gear through a coupling, and the bottom of the drive gear is vertically equipped with a stabilizer bar. The surface of the stabilizer bar is horizontally equipped with fan blades, and driven gears are installed on both sides of the drive gear.

[0007] Furthermore, the neutralization tank includes a main tank body, an exhaust pipe, an observation window, and a lower tank body. An exhaust pipe is installed at the lower end of one side of the main tank body, and observation windows are symmetrically installed on the side of the main tank body away from the exhaust pipe. The lower tank body is installed at the bottom of the main tank body.

[0008] Furthermore, the main tank and the lower tank are connected by a flange, and the vent pipe is welded to the main tank. Moreover, a flange structure is provided at the end of the vent pipe away from the main tank.

[0009] Furthermore, the spray structure includes a cross three-way valve, a connecting hose, a connector, and an atomizing nozzle. Both ends of the cross three-way valve are connected to connecting hoses, and a connector is installed at the end of the cross three-way valve closer to the neutralization tank. An atomizing nozzle is installed at the end of the connector away from the cross three-way valve.

[0010] Furthermore, the cross three-way valve, connecting hose, connector and atomizing nozzle are all structurally connected by a union joint, and the cross three-way valve is distributed in a ring array around the neutralization tank on the outside of the neutralization tank, and the output end of the atomizing nozzle is located inside the neutralization tank.

[0011] Furthermore, the top cover includes a cap, an air inlet pipe, and a sealing ring. The air inlet pipe is vertically installed through one end of the top of the cap, and a sealing ring is provided at the bottom edge of the cap.

[0012] Furthermore, the sealing ring is connected to the neutralization tank by a flange, and the sealing ring and the cover are integrally formed.

[0013] Furthermore, the driving gear and the driven gear are meshed together, and a stabilizing rod is vertically mounted on the bottom axis of both the driving gear and the driven gear. The fan blades are arranged at equal intervals from top to bottom on the surface of the stabilizing rod, and the fan blades at the bottom of the driven gear are staggered with the fan blades at the bottom of the driving gear.

[0014] This utility model provides a chemical production tail gas neutralization and treatment device, which has the following beneficial effects:

[0015] 1. This utility model, by installing a baffle component in the middle of the upper cover, when the servo motor operates, will drive the active gear connected to it at the bottom to rotate axially in the vertical direction. This causes the stabilizing rod vertically installed at the bottom axis of the active gear, together with the fan blades equidistantly arranged on its surface, to rotate rapidly. At the same time, it will drive the driven gears on both sides of the active gear, which are also equipped with stabilizing rods and fan blades, to rotate synchronously. By using the above structure, the exhaust gas injected into the neutralization tank and the atomized neutralizing agent sprayed by the spray structure can be quickly and thoroughly mixed, so that the two react effectively, thereby ensuring the treatment effect and efficiency of the exhaust gas.

[0016] 2. This utility model features four sets of spray structures symmetrically arranged in the middle and upper and lower ends of the main tank of the neutralization tank. The cross three-way valve, connecting hose, connector, and atomizing nozzle are connected to each other using a union joint structure. This structure allows for flexible disassembly of the entire spray structure, facilitating maintenance. Furthermore, the main tank, lower tank, and upper cover of the neutralization tank are connected by flange structures, ensuring sufficient connection stability and sealing while allowing for disassembly of the structures for easy internal maintenance and cleaning. The arrangement of the spray structures and their annular structure also ensures maximum mixing of the sprayed neutralizing agent with the exhaust gas injected into the neutralization tank, guaranteeing the quality of exhaust gas treatment.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 3As shown, a chemical production tail gas neutralization treatment device includes a neutralization tank 1 and a turbulence-inducing assembly 4. A spray structure 2 is installed on the surface of the neutralization tank 1, and a top cover 3 is installed on the top of the neutralization tank 1. The turbulence-inducing assembly 4 is installed through the middle of the top cover 3. The turbulence-inducing assembly 4 includes a servo motor 401, a drive gear 402, a stabilizer bar 403, fan blades 404, and a driven gear 405. The drive gear 402 is installed at the bottom power output end of the servo motor 401 via a coupling. The stabilizer bar 403 is vertically installed at the bottom of the drive gear 402, and fan blades 404 are horizontally installed on the surface of the stabilizer bar 403. Driven gears 405 are installed on both sides of the drive gear 402, and the drive gear 402 and driven gears 405 are meshed together. Furthermore, both the bottom shafts of the drive gear 402 and the driven gear 405 are vertically mounted with stabilizer bars 403, and fan blades 404 are equidistantly arranged on the surface of the stabilizer bars 403 from top to bottom. The fan blades 404 at the bottom of the driven gear 405 are staggered with the fan blades 404 at the bottom of the drive gear 402. When the servo motor 401 operates, it will drive the drive gear 402 connected to it at its bottom to rotate axially in the vertical direction. This will cause the stabilizer bars 403, which are vertically mounted on the bottom shaft of the drive gear 402, and the fan blades 404, which are equidistantly arranged on its surface, to rotate rapidly. At the same time, it will drive the driven gears 405, which are also mounted with stabilizer bars 403 and fan blades 404 on both sides of the drive gear 402, to rotate synchronously.

[0023] like Figures 1 to 3As shown, the neutralization tank 1 includes a main tank body 101, an exhaust pipe 102, an observation window 103, and a lower tank body 104. An exhaust pipe 102 is installed at the lower end of one side of the main tank body 101, and observation windows 103 are symmetrically installed vertically on the side of the main tank body 101 away from the exhaust pipe 102. The lower tank body 104 is installed at the bottom of the main tank body 101. The main tank body 101 and the lower tank body 104 are connected by a flange, and the exhaust pipe 102 is welded to the main tank body 101. A flange structure is provided at the end of 102 away from the main tank 101. The spray structure 2 includes a cross three-way valve 201, a connecting hose 202, a connector 203, and an atomizing nozzle 204. Both ends of the cross three-way valve 201 are connected to the connecting hose 202, and the connector 203 is installed at the end of the cross three-way valve 201 closest to the neutralization tank 1. The atomizing nozzle 204 is installed at the end of the connector 203 away from the cross three-way valve 201. The cross three-way valve 201 and the connecting hose 202... Both the connector 203 and the atomizing nozzle 204 are connected by a union joint. The cross-shaped three-way valves 201 are arranged in a ring array around the neutralizing tank 1 on its outer side. The output end of the atomizing nozzle 204 is located inside the neutralizing tank 1. The upper cover 3 includes a cap 301, an air inlet pipe 302, and a sealing ring 303. The air inlet pipe 302 is vertically installed through the top end of the cap 301, and a sealing ring 303 is provided at the bottom edge of the cap 301. The neutralization tank 1 is connected by a flange, and the sealing ring 303 and the cover 301 are integrated. Four sets of spray structures 2 are symmetrically arranged in the middle and at the top and bottom of the main tank body 101 of the neutralization tank 1. The cross three-way valve 201, connecting hose 202, connector 203 and atomizing nozzle 204 are connected to each other by a union joint structure. With the use of this structure, the entire spray structure 2 can be flexibly disassembled to facilitate structural maintenance.

[0024] In summary, as Figures 1 to 3 As shown, when using the chemical production tail gas neutralization treatment equipment, firstly, the spray structure 2 installed on the surface of the main tank 101 is connected to the external neutralizing agent supply equipment through a cross three-way valve 201 and a pipeline. Then, the upstream equipment is connected to the air inlet pipe 302 on the top of the cover 301 through a pipeline. After that, the downstream tail gas treatment equipment is connected to the air outlet pipe 102 on one side of the main tank 101 through a pipeline.

[0025] When the exhaust gas is injected into the neutralization tank 1, the turbulence assembly 4 and the spray structure 2 will operate synchronously. Under the delivery of the cross three-way valve 201 and the connecting hose 202, the neutralizing agent is injected into the atomizing nozzle 204 connected by the connector 203. Under the operation of the atomizing nozzle 204, the neutralizing agent will be atomized and sprayed into the entire interior of the neutralization tank 1.

[0026] Then the servo motor 401 installed on the top of the cover 301 starts to operate and drives the active gear 402 connected to its bottom to rotate. As the active gear 402 rotates, the driven gears 405 connected to its two sides will also rotate synchronously. This causes the stabilizing rod 403 with fan blades 404 installed on its surface to rotate synchronously at the bottom of the active gear 402 and the driven gear 405, so as to fully mix the exhaust gas with the atomizing agent. During the process, the interior of the neutralization tank 1 can be observed through the observation window 103 to check the specific situation inside.

[0027] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
