Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to waste gas treatment equipment for chemical safety management. Background Technology

[0002] Chemical waste gas refers to the toxic and harmful gases discharged from chemical plants during chemical production. Chemical waste gas can be divided into particulate pollutants and gaseous pollutants. Particulate pollutants include dust particles, particulate matter, smoke, mist, coal dust, etc. There are various purification methods for waste gas treatment. Among them, wet scrubbing technology is widely used due to its simple operation and low cost. Its core lies in using a spray method to wash the waste gas with liquid, thereby reducing the amount of dust and other particulate matter contained in the waste gas.

[0003] However, when using a single spray layer for natural spraying, the liquid that falls naturally is prone to insufficient contact between the waste gas and the liquid, which reduces the washing effect and directly affects the purification efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a waste gas treatment device for chemical safety management, so as to solve the problem that the existing waste gas treatment devices rely on a single spray layer for natural spraying, and the naturally sprayed liquid is prone to insufficient contact between waste gas and liquid, thereby reducing the washing effect and directly affecting the purification efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] A waste gas treatment device for chemical safety management includes a treatment cylinder and an air outlet and a water outlet respectively disposed on the top and bottom surfaces of the treatment cylinder. A water inlet pipe is disposed at the upper end of the treatment cylinder, and an air inlet pipe is disposed at the lower end of the treatment cylinder. The output ends of the water inlet pipe and the air inlet pipe are vertically opposite and coaxial. A baffle is disposed between the output ends of the water inlet pipe and the air inlet pipe. The bottom surface of the baffle is connected to the output end of the air inlet pipe, and an air outlet is disposed between the two. The top surface of the baffle protrudes upward to form a cone shape.

[0007] Further, the bottom surface of the baffle is provided with a sleeve that is fitted over the air intake pipe. The sleeve is slidably fitted with the air intake pipe. The sleeve and the air intake pipe are connected by an elastic support member. The air outlet is opened at the end of the sleeve near the baffle.

[0008] Furthermore, the bottom surface of the baffle is recessed upwards to form a cone shape.

[0009] Further, the output end of the water inlet pipe is provided with a conical plate, and the bottom surface of the conical plate is provided with a conical groove that matches the conical surface of the baffle. The conical groove is located on the sliding trajectory of the top surface of the baffle.

[0010] Further defined, the elastic support includes a groove formed on the sleeve, a support rod located in the groove, and an elastic element. The groove extends axially along the output end of the air intake pipe. The upper end of the elastic element is connected to the support rod, and the lower end is connected to the groove. One end of the support rod is connected to the air intake pipe.

[0011] Furthermore, sealing rings are provided at the connection points between the air inlet pipe and the water inlet pipe and the treatment cylinder.

[0012] Furthermore, the radius of the baffle is greater than the radius of the conical plate.

[0013] Further specified, a baffle is provided inside the air outlet, and an airflow channel is formed between the baffle and the air outlet. The top and bottom surfaces of the baffle are rotatably connected to the air outlet.

[0014] Furthermore, the cross-section of the spoiler is triangular.

[0015] Further, the air outlet is provided with an installation frame, the installation frame is detachably connected to the air outlet, and a filter screen is provided inside the installation frame.

[0016] The beneficial effects of this utility model are as follows:

[0017] Because the top surface of the baffle is a cone shape with the center protruding upwards, and the output end of the water inlet pipe is coaxial with the baffle, when the cleaning liquid output from the water inlet pipe into the treatment cylinder hits the cone surface at the top of the baffle, the cleaning liquid spreads and flows around the cone surface to form a water curtain or a combination of water curtain and water droplets. Compared with the prior art of using a nozzle to wash the exhaust gas, this utility model washes the exhaust gas by using a water curtain or a combination of water curtain and water droplets, which significantly expands the coverage area of ​​the cleaning liquid in contact with the exhaust gas.

Therefore, they should not be construed as limitations on this utility model.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a waste gas treatment device for chemical safety management, including a treatment cylinder 1 and an air outlet 101 and a water outlet 102 respectively disposed on the top and bottom surfaces of the treatment cylinder 1. A water inlet pipe 103 is disposed at the upper end of the treatment cylinder 1, and an air inlet pipe 104 is disposed at the lower end of the treatment cylinder 1. The output end of the water inlet pipe 103 and the output end of the air inlet pipe 104 are vertically opposite and coaxial. A baffle 2 is disposed between the output end of the water inlet pipe 103 and the output end of the air inlet pipe 104. The bottom surface of the baffle 2 is connected to the output end of the air inlet pipe 104, and an air outlet 301 is disposed between the two. The top surface of the baffle 2 protrudes upward to form a cone shape.

[0031] In this solution, an upward-facing air inlet pipe 104 and a downward-facing water inlet pipe 103 are installed inside the treatment cylinder 1. A baffle 2 is positioned above the air inlet pipe 104 to block the flow of cleaning liquid into the air inlet pipe 104, thereby reducing the occurrence of cleaning liquid entering the air inlet pipe 104.

[0032] Since the top surface of the baffle 2 is a cone shape with the center protruding upwards, and the output end of the water inlet pipe 103 is coaxial with the baffle 2, when the cleaning liquid output from the output end of the water inlet pipe 103 into the treatment cylinder 1 hits the cone surface at the top of the baffle 2, the cleaning liquid spreads and flows around the cone surface and forms a water curtain or a combination of water curtain and water droplets. Compared with the prior art of using a nozzle to wash the exhaust gas, this utility model washes the exhaust gas by using a water curtain or a combination of water curtain and water droplets, which significantly expands the coverage area of ​​the cleaning liquid in contact with the exhaust gas.

[0033] In practical use, the cleaning liquid and exhaust gas are respectively transported to the treatment cylinder 1 through the water inlet pipe 103 and the air inlet pipe 104. Under the action of pressure and gravity, the cleaning liquid is discharged through the output end of the water inlet pipe 103 and impacts the top surface of the baffle 2. The cleaning liquid is diffused and flows through the conical surface at the top of the baffle 2 to form a water curtain or a combination of water curtain and water droplets. The water curtain covers the air inlet pipe 104. The exhaust gas discharged through the air outlet 101 of the air inlet pipe 104 floats upward and passes through the water curtain, thus completing the exhaust gas washing operation.

[0034] Among them, the air outlet 101 is located on the top surface of the treatment cylinder 1, which facilitates the natural upward discharge of the waste gas after the particulate matter is washed.

[0035] The water outlet 102 is located on the bottom surface of the treatment cylinder 1, which facilitates the natural downward discharge of the cleaning liquid after the waste gas is washed. Both the air outlet 101 and the water outlet 102 are equipped with flanges, which can be connected to conveying pipes to transport the washed waste gas and cleaning liquid separately.

[0036] To achieve better performance, a conical structure can be provided on the top surface of the baffle 2. The lower end of the conical structure is connected to the baffle 2, and the upper end is located inside the output end of the water inlet pipe 103. The diameter of the lower end of the conical structure is smaller than the diameter of the water inlet pipe 103, and a gap is formed between the upper end of the conical structure and the inner wall of the water inlet pipe 103 to allow the cleaning liquid to pass through. The cleaning liquid can more easily form a water curtain on the top surface of the baffle 2 by passing through the conical surface of the conical structure and the gap.

[0037] In this embodiment, a sleeve 3 is provided on the bottom surface of the baffle 2 and is sleeved outside the air intake pipe 104. The sleeve 3 is slidably engaged with the air intake pipe 104. The sleeve 3 and the air intake pipe 104 are connected by an elastic support member 4. The air outlet 301 is opened at one end of the sleeve 3 near the baffle 2.

[0038] In this scheme, the baffle 2 is slidably engaged with the air inlet pipe 104 through the sleeve 3, and the bottom surface of the baffle 2 is located on the opening at the output end of the air inlet pipe 104. Therefore, the exhaust gas discharged from the air inlet pipe 104 will first hit the baffle 2, and then be discharged into the inner cavity of the treatment cylinder 1 through the air outlet 301.

[0039] When the exhaust gas flow rate increases, the air pressure generated by the exhaust gas will push the baffle 2 and the sleeve 3 to move upward along the length of the intake pipe 104 and compress the elastic support 4, causing the elastic support 4 to store elastic energy.

[0040] In this embodiment, the bottom surface of the baffle 2 is recessed upward to form a cone shape.

[0041] In this embodiment, the output end of the water inlet pipe 103 is provided with a conical plate 5, and the bottom surface of the conical plate 5 is provided with a conical groove that matches the conical surface of the baffle 2. The conical groove is located on the sliding trajectory of the top surface of the baffle 2.

[0042] In this scheme, a conical plate 5 is set directly above the baffle 2, and the conical surface of the bottom of the conical plate 5 is adapted to the conical surface of the top of the baffle 2. This causes the baffle 2 to move upward to a certain extent, and the water curtain formed on the top surface of the baffle 2 comes into contact with the bottom surface of the conical plate 5. As the baffle 2 continues to move upward, the distance between the baffle 2 and the conical plate 5 is reduced, which squeezes the water curtain, thereby expanding the range of the formed water curtain and increasing the pressure of the water curtain. This forms a high-speed water flow, which significantly increases the contact effect between the water curtain formed by the cleaning liquid and the exhaust gas, thereby enhancing the washing effect.

[0043] In this embodiment, the elastic support 4 includes a groove 401 formed on the sleeve 3, a support rod 402 located in the groove 401, and an elastic element 403. The groove 401 extends axially along the output end of the air intake pipe 104. The upper end of the elastic element 403 is connected to the support rod 402, and the lower end is connected to the groove 401. One end of the support rod 402 is connected to the air intake pipe 104.

[0044] In this scheme, the sliding groove 401 and the support rod 402 cooperate to constrain the movable range of the sleeve 3. When the sleeve 3 moves up or down to a certain extent, the support rod 402 abuts against the lower end or the upper end of the sliding groove 401, thereby limiting the sleeve 3 and preventing the baffle 2 from moving up to fit against the bottom surface of the conical plate 5 through the limiting effect.

[0045] The support rod 402 and the elastic element 403 cooperate to form an elastic support structure that pushes the sleeve 3 downward. When the elastic element 403 is naturally extended, the upper end of the elastic element 403 abuts against the fixed support rod 402 to form a fulcrum, and the other end pushes the sleeve 3 downward through its own elasticity, so that the support rod 402 is located at the upper end of the slide groove 401. At this time, the downward movement range of the sleeve 3 reaches the limit and is in a state where it can move upward.

[0046] When the exhaust gas flow increases, the resulting air pressure pushes the baffle 2 and sleeve 3 upward. At this time, the air pressure increases so much that it overcomes the elastic force of the elastic element 403, thereby pushing the baffle 2 and sleeve 3 upward and causing the elastic element 403 to perform elastic energy storage.

[0047] Among them, the elastic element 403 can be a cylindrical spring, a conical spring or a disc spring, etc.

[0048] In this embodiment, sealing rings 6 are provided at the connection points between the air inlet pipe 104 and the water inlet pipe 103 and the treatment cylinder 1.

[0049] In this design, the sealing ring 6 (such as a rubber O-ring) fills the gap at the connection between the air inlet pipe 104 / water inlet pipe 103 and the treatment cylinder 1, thereby enhancing the sealing performance of the treatment cylinder 1.

[0050] In this embodiment, the radius of the baffle 2 is greater than the radius of the conical plate 5.

[0051] In this design, the radius of the baffle 2 is larger than that of the conical plate 5, ensuring that the baffle 2 always completely covers the opening of the conical groove during the upward movement of the sleeve 3, thus preventing edge leakage.

[0052] In this embodiment, a baffle plate 7 is provided inside the air outlet 301, and an airflow channel is formed between the baffle plate 7 and the air outlet 301. The top and bottom surfaces of the baffle plate 7 are rotatably connected to the air outlet 301.

[0053] In this scheme, when the exhaust gas is discharged to the treatment cylinder 1 through the exhaust port 301, the generated airflow impacts the baffle plate 7, driving it to rotate around the axis and collide with the exhaust gas.

[0054] That is, when the exhaust gas passes through the exhaust port 301, it is cut into multiple vortices by the rotating baffle plate 7, increasing the probability of collision with the droplets.

[0055] The rotatable connection between the baffle 7 and the air outlet 301 can be sealed to enhance corrosion resistance.

[0056] In this embodiment, the cross-section of the spoiler 7 is triangular.

[0057] In this design, the sharp edges of the triangular baffle 7 create a low-pressure zone, enhancing the airflow shearing effect and improving droplet capture efficiency.

[0058] In this embodiment, the air outlet 101 is provided with an installation frame, the installation frame is detachably connected to the air outlet 101, and a filter screen 8 is provided inside the installation frame.

[0059] In this solution, filter 8 (such as stainless steel wire mesh) adsorbs droplets and unremoved particles carried by aerosols;

[0060] Meanwhile, the detachable installation of the mounting frame and the air outlet 101 (such as the mounting frame being inserted into the air outlet 101) allows the mounting frame to be disassembled for easy flushing or replacement of the clogged filter screen 8.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
