Description

Technical Field

[0001] This application relates to the technical field of high-temperature waste gas treatment, and in particular to a sulfurized steam emission treatment device. Background Technology

[0002] Vulcanization is a major step in the production of rubber hoses. Currently, steam is often used to enter from one end of the hose and exit from the other end. The steam flows in the pipe and expands the hose under a certain steam pressure. Under the action of steam temperature, the hose reaches the vulcanization temperature. After a period of time, the raw rubber inside the flat hose can be vulcanized into mature rubber.

[0003] Waste gas and particulate matter generated during vulcanization are discharged along with high-temperature steam. Some of these components can be harmful to human health and the environment. Moreover, the high temperature of the discharged steam increases the risk of injury to workers in the workplace. Therefore, the applicant believes it is necessary to design an effective and practical emission treatment device for the high-temperature vulcanization waste steam of rubber hoses. Utility Model Content

[0004] In order to improve the problem that the direct emission of high-temperature waste gas from rubber hose vulcanization poses a hazard to personnel and the environment, the purpose of this application is to provide a vulcanization steam emission treatment device that can effectively reduce the temperature and pollutant content of the emitted rubber hose vulcanization waste steam.

[0005] To achieve the objectives of this application, a sulfidation steam emission treatment device is provided, which adopts the following technical solution:

[0006] A sulfurized steam emission treatment device, comprising:

[0007] A water tank containing water, the water tank being provided with an air inlet and an air outlet, the air inlet being located below the water surface in the water tank, and the air outlet being located above the water surface in the water tank;

[0008] The cooling circulation pipe is located below the water surface of the water tank, and the cooling circulation pipe extends to the outside of the water tank and is connected to a cooling device;

[0009] A circulating pump is connected to the water tank. The pump's suction pipe extends below the water surface in the water tank, and the pump's outlet pipe is located inside the water tank and above the water surface. The outlet pipe of the circulating pump is connected to a spray device.

[0010] In the above technical solution, the cooling circulation pipeline continuously cools the water in the water tank, and the high-temperature waste steam after sulfidation enters the water in the water tank through the air inlet.

[0011] First, the water tank cools the high-temperature exhaust gas: as the high-temperature exhaust steam rises from the bottom of the tank, it fully exchanges heat with the water. On one hand, some of the exhaust steam condenses in the tank and remains there as a cooling medium, reducing the amount of exhaust steam emitted. On the other hand, some of the exhaust steam that hasn't condensed after heat exchange is cooled by the water in the tank. Then, as the exhaust gas rises, the circulating pump continuously pumps water from the tank above the surface and sprays it, providing a secondary cooling effect on the uncondensed exhaust gas, effectively reducing the risk of thermal damage from the emitted exhaust gas.

[0012] Secondly, the water tank plays a role in separating waste steam: as the waste steam rises from the bottom of the water tank, some of the water-soluble harmful gases will dissolve in the water; some of the larger pollutants carried by the high-temperature waste steam will gradually settle at the bottom of the water tank. At the same time, some smaller pollutants are also easy to settle during the spraying process of the circulating pump, thereby effectively reducing the content of harmful substances in the exhaust gas.

[0013] Therefore, the vulcanization steam emission treatment device described above can effectively cool down the vulcanization waste steam of rubber hoses and reduce the content of harmful substances, which is beneficial to improving the safety and environmental protection of rubber hose production.

[0014] The implementation can include any or all of the following features.

[0015] Furthermore, the air inlet is located near the bottom of the water tank and also includes an air supply pipe. The end of the air inlet located outside the water tank is connected to the air supply pipe. The air supply pipe includes a first pipe and a second pipe. The first pipe is connected to the second pipe. The first pipe and the air inlet are at the same height, and the second pipe is higher than the water surface of the water tank.

[0016] The steam used for vulcanizing rubber hoses has a certain pressure, making the air pressure on the inlet side of the delivery pipe greater than that on the water tank side. This prevents backflow of water from the tank. Therefore, this technical solution designs the air inlet close to the bottom of the water tank, which prolongs the time the waste steam spends in the water, allowing for more thorough contact between the waste steam and the water, thus improving the cooling and separation effect. Simultaneously, to prevent backflow of water from the tank, this technical solution incorporates a bend and elevation design in the gas delivery pipe, ensuring that the lowest point of the gas delivery pipe, i.e., the first pipe, is not lower than the height of the water tank. Even if water enters the gas delivery pipe, further backflow will not occur, thereby ensuring the normal operation of this vulcanizing steam emission treatment device.

[0017] Furthermore, the end of the gas supply pipe located inside the water tank is closed, and several holes are opened on the side of the pipe wall of the gas supply pipe located inside the water tank facing the bottom of the water tank, and the holes are arranged in the opposite direction along the length of the gas supply pipe.

[0018] The above technical solution not only further prevents water backflow, but also disperses the waste steam introduced into the water through several holes, increasing the contact area between the waste steam and the water, which helps to improve the efficiency of the water tank in condensing and cooling the waste steam.

[0019] Furthermore, a one-way valve is installed inside the second pipe. The one-way valve opens in the direction of exhaust gas delivery, and the position of the one-way valve is higher than the water surface of the water tank.

[0020] This plan further prevents backflow of water from the tank by using a one-way valve design.

[0021] Furthermore, the outlet pipe of the circulating pump is equipped with several spray heads.

[0022] The design of multiple spray heads helps to improve the spraying effect, thereby improving the cooling efficiency of the exhaust gas.

[0023] Furthermore, the water tank is also equipped with an overflow outlet, which is located near the water surface. When the condensed waste steam in the tank causes the water level to exceed the overflow outlet, water will flow out from the overflow outlet. This helps control the water level in the tank, providing secondary cooling space for uncondensed waste gas. It also helps control the water pressure in the tank within a certain range, preventing backflow. Moreover, the overflow continuously refreshes the water in the tank, preventing the water concentration from becoming too high and making it difficult to dissolve some water-soluble harmful gases.

[0024] Furthermore, a wastewater treatment device is connected to the end of the overflow outlet located outside the water tank. The wastewater overflowing from the water tank is further treated by the wastewater treatment device to meet discharge standards.

[0025] Furthermore, an exhaust gas treatment device is connected to the end of the exhaust gas outlet located outside the water tank. The exhaust gas discharged from the water tank is further treated by the exhaust gas treatment device to meet emission standards.

[0026] Furthermore, the air inlet is positioned close to the cooling circulation pipeline. This technical solution enables better cooling of the high-temperature waste steam entering the water tank.

[0027] Furthermore, a water inlet is provided on the top of the water tank. The water inlet is used to inject clean water into the water tank.

[0028] In summary, this application provides a sulfurized steam emission treatment device, which has the following beneficial effects:

[0029] Firstly, this application provides a cooling circulation pipe for the water in the water tank, enabling the water in the tank to effectively condense, cool, and separate the high-temperature waste steam. This allows for the effective treatment of vulcanization waste steam from rubber hoses at a relatively low cost, improving the safety and environmental friendliness of rubber hose production.

[0030] Secondly, this application solves the problem of water backflow in the water tank by designing the gas transmission pipeline, allowing the air inlet to be designed close to the bottom of the water tank, which further enhances the water tank's effect on condensing, cooling, and separating high-temperature waste steam.

[0031] Finally, this application achieves the effect of automatically updating and controlling the water level in the water tank as the treatment process progresses through the design of the overflow port, which has a beneficial effect on the separation of waste steam and the prevention of water backflow in the water tank.

[0041] To make the objectives and technical solutions of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the described embodiments of this application without creative effort are within the scope of protection of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, back, bottom, and top, are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting this application.

[0042] This application discloses a device for treating sulfurized steam emissions. (Refer to...) Figure 1 The system includes a water tank 1 filled with water. A cooling circulation pipe 23 is coiled below the water surface in the water tank 1, and a cooling device 2 is connected to the cooling circulation pipe 23. The cooling device 2 circulates and cools the medium in the cooling circulation pipe 23, and then continuously cools the water in the water tank 1 through the cooling circulation pipe 23, thus condensing and cooling the high-temperature waste steam entering the water tank 1. Preferably, the cooling circulation pipe 23 is U-shaped and coiled below the water surface along the height of the water tank 1. Figure 1 Only one U-bend of the cooling circulation pipe 23 is shown, but the number of U-bends in the cooling circulation pipe 23 is not affected. Figure 1 The number of bends shown is limited, and the device can continue to bend upwards in a U-shape along the height direction of the water tank 1 multiple times before extending out of the water tank 1 and connecting to the cooling device 2.

[0043] Reference Figure 1 Specifically, the water tank 1 has an inlet 11 and an outlet 12 near the bottom on one side. The cooling circulation pipe 23 is connected to the output end 21 of the cooling device 2 and extends into the water tank 1 from the inlet 11 in the direction of arrow A. After coiling in the water tank 1, it extends out of the water tank 1 from the outlet 12 and connects to the input end 22 of the cooling device 2. The cooling device 2 can be an existing circulating cooling water treatment device or other existing cooling medium circulation treatment device.

[0044] Reference Figure 1A circulation pump 3 is connected to a water tank 1. The figure shows the circulation pump 3 installed on the top surface of the water tank 1. In other embodiments, the circulation pump 3 can also be installed on the upper part of the side wall of the water tank 1, or it can be installed adjacent to the water tank 1 via a bracket. The height of the bracket can be equal to or higher than the height of the water tank 1. The pump 3's suction pipe 31 extends downwards into the water surface, and its outlet pipe 32 extends into the water tank 1, with its end close to the top of the water tank 1. Several branch pipes 33 are connected in parallel to the end of the outlet pipe 32, and each branch pipe 33 has a spray head (not shown in the figure) installed at its end. The circulation pump 3 is used to transport water from the water tank 1 to the top of the water tank 1 and spray it downwards in the direction of arrow B to cool the exhaust gas in the water tank 1.

[0045] Reference Figure 1 An air inlet 13 is provided on the side wall of water tank 1 near the bottom of water tank 1. An air supply pipe 4 is connected to the air inlet 13. The air supply pipe 4 passes the waste steam after the rubber hose vulcanization into water tank 1 in the direction of arrow C.

[0046] Reference Figure 1 The air inlet 13 is positioned facing and close to the cooling circulation pipe 23 to enhance the condensation and cooling effect of the cooling circulation pipe 23 on the waste steam. The air supply pipe 4 includes a first pipe 41 and a second pipe 42. The first pipe 41 is at the same height as the air inlet 13. The second pipe 42 is formed by alternating vertical pipes 421 and horizontal pipes 422, creating an inverted U-shape. The highest point of the second pipe 42, i.e., the horizontal pipe 422, is at least higher than the water surface of the water tank 1. Preferably, the horizontal pipe 422 of the second pipe 42 is flush with or slightly higher than the top of the water tank 1. The end of the air inlet 13 located outside the water tank 1 is sequentially connected to the first pipe 41, the second pipe 42, and the first pipe 41 again; that is, the first pipe 41 is connected to both sides of the second pipe 42. The arrangement of the air supply pipes 4 prevents backflow of water from the water tank 1.

[0047] Reference Figure 1 and Figure 2 The first pipe 41 of the gas transmission pipe 4 extends horizontally from the air inlet 13 into the water in the water tank 1. The end of the first pipe 41 extending into the water tank 1 is closed, and several holes 411 are formed in the pipe wall of the first pipe 41 on the side facing the bottom of the water tank 1. The holes 411 are arranged along the length of the first pipe 41. The sulfurized waste steam entering the water tank 1 through the first pipe 41 flows along... Figure 2 The direction of the middle arrow D is through the hole 411 into the water. The structural design of the gas supply pipe 4 located in the water tank 1 serves two purposes: firstly, it further prevents water backflow; secondly, the hole 411 disperses the high-temperature waste steam entering the water, which helps to improve the efficiency of waste steam condensation and cooling.

[0048] Reference Figure 1To further prevent backflow of groundwater in water tank 1, a one-way valve 43 is also installed in the horizontal pipe 422 of the second pipeline 42. The one-way valve 43 opens in the direction of exhaust gas delivery.

[0049] Reference Figure 1 Furthermore, an outlet 14 is provided on the top surface or side wall of the water tank 1 near the top of the water tank 1 to discharge uncondensed waste gas from the water tank 1. The outlet 14 is connected to an external waste gas treatment device 5 to further treat the waste gas discharged from the water tank 1 to meet emission standards. The waste gas treatment device 5 can be an existing absorption-type waste gas treatment device, such as an activated carbon absorption-type waste gas treatment device.

[0050] Reference Figure 1 Furthermore, the water tank 1 is also equipped with an overflow port 15, which is located on the side wall of the water tank 1 and close to the water surface. The overflow port 15 is connected to the sewage treatment equipment 6. When the waste steam introduced into the water tank 1 condenses, causing the water level in the water tank 1 to rise to the overflow port 15, the excess water will be discharged from the overflow port 15 into the sewage treatment equipment 6 for further treatment. The overflow can continuously refresh the water in the water tank 1, preventing the water concentration in the water tank 1 from becoming too high and making it difficult to dissolve water-soluble gases. Moreover, the overflow can control the water level in the water tank 1 within a certain range, providing secondary cooling space for uncondensed waste gas, and controlling the water pressure in the water tank 1 to prevent backflow into the gas transmission pipeline 4.

[0051] Reference Figure 1 The top of the water tank 1 is also provided with a water inlet 16 for filling the water tank 1 with water.

[0052] Reference Figure 1 The implementation process of a sulfurized steam emission treatment device in this application embodiment is as follows: clean water is injected into the water tank 1 from the water inlet 16, the water level is below the overflow outlet 15, and the water in the water tank 1 is continuously cooled through the cooling circulation pipe 23.

[0053] Waste steam from the vulcanized rubber hose, transported by gas pipeline 4, enters water tank 1 through inlet 13. It comes into contact with water continuously cooled by cooling circulation pipe 23 within water tank 1. As the waste steam rises from the bottom, some condenses into water. Simultaneously, water-soluble harmful gases or solids in the waste steam gradually dissolve in the water of water tank 1. The uncondensed waste steam continues to rise above the water surface and is further cooled by the condensate sprayed by circulation pump 3. The cooled waste steam exits water tank 1 through outlet 14 and enters waste gas treatment device 5. Once a certain amount of waste steam condenses in the water of water tank 1, the water flows out from overflow outlet 15 and enters wastewater treatment equipment 6. Water-insoluble solid particles contained in the waste steam gradually settle to the bottom of water tank 1.

[0054] After the sulfurized steam emission treatment device has been working for a period of time, the wastewater in the water tank 1 can be pumped into the sewage treatment equipment 6 for treatment by the circulating pump 3. The insoluble matter at the bottom of the water tank 1 can be pumped out and treated by the pump for pumping mud. The bottom of the water tank 1 can be cleaned and then clean water can be injected from the water inlet 16 for continued use.

[0055] Of course, the above embodiments are the best embodiments of this application, and are only used to illustrate the technical concept and features of this application. Their purpose is to enable those skilled in the art to understand the content of this application and implement it accordingly, and they should not be used to limit the scope of protection of this application. All modifications made in accordance with the spirit of the main technical solution of this application should be included within the scope of protection of this application.
