Abstract
Description
Technical Field
[0001] This application relates to the technical field of sulfur foam treatment and resource recovery in chemical production, and in particular to a sulfur foam acid thickening device. Background Technology
[0002] In chemical production processes, especially in the desulfurization stage, a large amount of sulfur foam is generated. The main components of sulfur foam include elemental sulfur, desulfurization liquid, and water. In order to realize the recovery and utilization of sulfur resources, it is usually necessary to convert sulfur foam into acid. Before acid production, thickening treatment of sulfur foam is a crucial step.
[0003] Some existing thickening equipment uses filtration for thickening, but due to the high viscosity of sulfur foam, it easily clogs the filter screen, increasing the frequency and cost of equipment maintenance and affecting the continuity of production. Furthermore, some thickening equipment cannot effectively remove moisture from the sulfur foam during the process, resulting in a still high liquid content in the thickened sulfur paste. This increases energy consumption and reduces acid production efficiency in subsequent acid production processes.
[0004] Regarding the aforementioned technologies, the applicant believes that there is a defect in the filter screen being prone to clogging during the filtration and thickening process. Utility Model Content
[0005] To address the aforementioned technical problems, this application provides a sulfur foam acid thickening device.
[0006] This application provides a sulfur foam acid thickening device, which adopts the following technical solution:
[0007] A sulfur foam acid thickening device includes a frame, on which a housing and a thickener are mounted. The housing is mounted on top of the frame and is detachably connected to the frame. The thickener is mounted on the frame at the bottom of the housing and is detachably connected to the frame. A feed inlet is provided at the top of the housing and is fixedly connected to the housing. A discharge outlet is provided at the bottom of the thickener and is fixedly connected to the thickener. A filtration mechanism and an evaporation mechanism are sequentially arranged inside the housing. The filtration mechanism is installed inside the housing below the feed inlet and is detachably connected to the housing. The evaporation mechanism is installed on the housing after the filtration mechanism and is detachably connected to the housing. The thickener is detachably connected to the housing.
[0008] By adopting the above technical solution, the shell is installed on the top of the frame and is detachably connected to the frame. The thickener is installed on the frame at the bottom of the shell and is detachably connected to the frame. Inside the shell, a filtration mechanism and an evaporation mechanism are arranged in sequence. The filtration mechanism first removes large particulate impurities and some moisture from the sulfur foam, so that the solid content of the material entering the evaporation mechanism is initially increased, reducing the probability of sulfur particles coking on the surface of the heating tube during subsequent evaporation and reducing secondary clogging of the filter screen caused by the backflow of coking material. The evaporation mechanism vaporizes a large amount of water by heating, further reducing the viscosity of the material. The thickener prevents the material from settling and caking by stirring, reducing the impact of high-viscosity material on the filter screen.
[0009] Preferably, an umbrella-shaped diffuser is provided at the feed inlet inside the shell, and the umbrella-shaped diffuser is fixedly connected to the feed inlet inside the shell. An adjusting valve is provided on the outside of the discharge port of the thickener, and the adjusting valve is detachably connected to the discharge port.
[0010] By adopting the above technical solution, the umbrella diffuser has an umbrella-shaped structure. When sulfur foam enters the shell from the feed inlet, it will be guided by the curved surface of the diffuser to be evenly dispersed in all directions, avoiding the material from concentrating and impacting a certain area. By adjusting the valve opening, the processing time of the material in the equipment can be extended, and the solid content of the output material is higher, which is suitable for scenarios that require high concentration of sulfur foam.
[0011] Preferably, the filtration mechanism includes a filter screen device and a vibration auxiliary component. The filter screen device is installed inside the housing and is elastically connected to the housing. The vibration auxiliary component is installed on the filter screen device and is detachably connected to the filter screen device.
[0012] By adopting the above technical solution, the filter device is connected to the housing through an elastic element. When the vibration auxiliary component is working, it will generate mechanical vibration. The elastic connection can absorb the vibration energy and avoid the vibration being directly transmitted to the housing, causing fatigue damage to the equipment. At the same time, it reduces operating noise and improves equipment reliability. The vibration auxiliary component effectively prevents the filter from clogging.
[0013] Preferably, the filter device includes a main filter layer, a support layer, and a filter frame. The main filter layer is mounted on the support layer and is fixedly connected to the support layer. The main filter layer and the support layer are connected to the filter frame by bolts. Grooves are provided at corresponding positions on the housing and the filter frame, and sealing gaskets are provided on the grooves. The filter frame is elastically connected to the housing.
[0014] By adopting the above technical solution, the main filter layer, as the filter medium that directly contacts the sulfur foam, bears the pressure differential load during sulfur foam filtration, preventing the main filter layer from cracking or denting due to excessive pressure. The main filter layer and the support layer are fixed to the filter frame with bolts.
[0015] Preferably, the vibration auxiliary component includes an electromagnetic vibrator and spring damping supports. The electromagnetic vibrator is installed on both sides of the filter frame and is detachably connected to the filter frame. Multiple spring damping supports are evenly distributed and installed at the bottom of the filter frame. One end of each spring damping support is detachably connected to the housing, and the other end of each spring damping support is detachably connected to the filter frame.
[0016] By adopting the above technical solution, the electromagnetic vibrator and the filter frame are detachably connected. The electromagnetic vibrator generates an alternating magnetic field by energizing the electromagnetic coil, which drives the armature to reciprocate, thereby applying high-frequency vibration to the filter frame. The spring damping support is installed at the bottom of the filter frame. The elastic deformation of the spring absorbs the vibration energy generated by the electromagnetic vibrator, preventing the vibration from being transmitted to the shell, avoiding the loosening of bolts in the shell due to long-term vibration, and reducing the impact of vibration on the equipment foundation.
[0017] Preferably, the evaporation mechanism includes a heating chamber, an evaporation chamber, and a circulation mechanism. The heating chamber and the circulation mechanism are detachably connected to the housing. The evaporation chamber is installed below the heating chamber and is detachably connected to the heating chamber. One end of the circulation mechanism is connected to the heating chamber, and the other end of the circulation mechanism is connected to the evaporation chamber. An outlet is provided at the bottom of the circulation mechanism, and the circulation mechanism is detachably connected to the thickener.
[0018] By adopting the above technical solution, the heating chamber ensures that the heating temperature is stable within the optimal range for sulfur foam evaporation. During flow, it fully contacts the heat medium to achieve efficient heat transfer. The evaporation chamber is installed below the heating chamber, and gravity or circulating power is used to make the heated sulfur foam enter the evaporation chamber for flash evaporation, thereby enhancing gas-liquid separation and improving the evaporation effect.
[0019] Preferably, a flow guiding device is provided between the filtration mechanism and the heating chamber, the other end of the flow guiding device is connected to the heating chamber, and a check valve is provided between the flow guiding device and the heating chamber, wherein the check valve is detachably connected to the flow guiding device.
[0020] By adopting the above technical solution, the flow guiding device is usually connected to the filter mechanism and the heating chamber, guiding the filtered sulfur foam smoothly into the heating chamber, avoiding material accumulation or uneven flow rate caused by path bends. The check valve is installed between the flow guiding device and the heating chamber, allowing sulfur foam to flow from the filter mechanism to the heating chamber only, and preventing steam backflow from the heating chamber.
[0021] Preferably, the thickener includes a tank, a stirring device, a rotating shaft, and a motor. The tank is installed on the outlet and is detachably connected to the outlet. The motor is installed on the top of the tank and is detachably connected to the housing. One end of the rotating shaft is connected to the motor, and the other end of the rotating shaft is connected to the stirring device and placed at the bottom of the housing. The rotating shaft is rotatably connected to the housing.
[0022] By adopting the above technical solution, the tank body and outlet, as well as the motor and shell, are detachably connected. The motor drives the rotating shaft to rotate the stirring device. The stirring device can break the viscous structure in the sulfur foam, so that the solid particles are evenly dispersed, preventing the accumulation of material at the bottom of the tank due to gravity settling. The shearing force generated by stirring breaks the bubble film in the sulfur foam, promotes the release of encapsulated moisture, and, together with the filtered or evaporated material, can further increase the solid content.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] The housing is mounted on top of the frame and is detachably connected to the frame. The thickener is mounted on the frame at the bottom of the housing and is detachably connected to the frame. Inside the housing, a filtration mechanism and an evaporation mechanism are arranged in sequence. The filtration mechanism first removes large particulate impurities and some moisture from the sulfur foam, which initially increases the solid content of the material entering the evaporation mechanism, reducing the probability of sulfur particles coking on the surface of the heating tubes during subsequent evaporation and reducing secondary clogging of the filter screen caused by the backflow of coking material. The evaporation mechanism vaporizes a large amount of moisture through heating, further reducing the viscosity of the material. The thickener prevents the material from settling and caking by stirring, reducing the impact of high-viscosity material on the filter screen.
[0025] The filter device is connected to the housing through an elastic element. When the vibration auxiliary component is working, it will generate mechanical vibration. The elastic connection can absorb the vibration energy and prevent the vibration from being directly transmitted to the housing, causing fatigue damage to the equipment. At the same time, it reduces operating noise and improves equipment reliability. The vibration auxiliary component effectively prevents the filter from clogging. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0031] This application discloses a sulfur foam acid thickening device. (Refer to...) Figure 1-3 The system includes a frame 1, a housing 2 mounted on top of the frame 1, and the housing 2 bolted to the frame 1. A thickener 6 is mounted on the frame 1 below the housing 2 and bolted to the frame 1. The housing 2 is connected to the thickener 6. A feed inlet 21 is located at the top of the housing 2 and welded to the top. A discharge outlet 65 is located at the bottom of the thickener 6 and welded to the bottom. A regulating valve 66 is mounted on the discharge outlet 65. The regulating valve 66 is connected to... The discharge port 65 is detachably connected. Inside the housing 2, a filter mechanism 3 and an evaporation mechanism 5 are sequentially arranged. An umbrella-shaped diffuser 211 is installed at the inlet 21 inside the housing 2. The umbrella-shaped diffuser 211 has an umbrella-like structure. When sulfur foam enters the housing 2 from the inlet 21, it is guided by the curved surface of the umbrella-shaped diffuser 211 to be evenly dispersed in all directions. The filter mechanism 3 includes a filter screen device 31 and a vibration auxiliary component 4. The filter screen device 31 includes a main filter layer 311, a support layer 312, and a filter media. The filter frame 313 and the vibration auxiliary components include an electromagnetic vibrator 41 and a spring damping support 42. The filter frame 313 is connected to the housing 2 below the umbrella diffuser 211 via the spring damping support 42. A groove 22 and a sealing gasket 23 are provided at the housing 2 corresponding to the filter frame 313. The sealing gasket 23 is installed on the groove 22 to prevent sulfur foam from flowing out directly through the groove 22. The electromagnetic vibrator 41 is installed at the bottom of the filter frame 313 and is detachably connected to the filter frame 313. The main filter layer 311 and the support layer 312 are fixedly connected. The main filter layer 311 and the support layer 312 are connected to the filter frame 313 by bolts. The sulfur foam passes through the main filter layer 311 and the support layer 312 by gravity and the cooperation of the electromagnetic vibrator 41. The spring damping support 42 reduces the influence of the electromagnetic vibrator 41 on the housing 2, allowing the sulfur foam to enter the evaporation mechanism 5 through the guide device 54 provided between the filter mechanism 3 and the heating chamber 51.
[0032] Evaporation mechanism 5 includes heating chamber 51, evaporation chamber 52, and circulation mechanism 53. A check valve 55 is installed on the flow guiding device 54 to prevent steam backflow. One end of heating chamber 51 is connected to the flow guiding device 54 to allow filtered sulfur foam to enter. Heating chamber 51 and flow guiding device 54 are detachably connected. The heating medium in heating chamber 51 indirectly heats the sulfur foam. The other end of heating chamber 51 is connected to evaporation chamber 52, where heated sulfur foam enters. Circulation mechanism 53 is connected to both ends of heating chamber 51 and evaporation chamber 52, respectively, to extract material from the bottom of evaporation chamber 52, reheat it in heating chamber 51, and then return it to evaporation chamber 52, forming a closed loop. The bottom of circulation mechanism 53 has an outlet 531. Connected to the inlet of the thickener 6, after the sulfur foam completes the cycle heating and evaporation in the heating chamber 51 and the evaporation chamber 52, the increased solid content is transported to the thickener 6 through the outlet 531 for deep thickening. The thickener 6 includes a tank 61, a stirring device 62, a rotating shaft 63, and a motor 64. The thickener 6 enters the tank 61 through the inlet of the thickener 6. The tank 61 is bolted to the frame 1. The motor 64 provides rotation for the rotating shaft 63 and the stirring device 62. One end of the rotating shaft 63 is connected to the motor 64, and the other end of the rotating shaft 63 is connected to the stirring device 62. The motor 64 drives the rotating shaft 63 to drive the stirring device 62 to rotate. The shear force generated by stirring breaks the bubble film in the sulfur foam, promotes the release of the encapsulated water, and thickens the sulfur foam.
[0033] The working principle of the sulfur foam acid thickening device in this application is as follows: The sulfur foam material to be processed enters the equipment through the feed inlet 21 at the top of the shell 2. The feed inlet 21 is connected to an umbrella-shaped diffuser 211. The sulfur foam is more evenly dispersed through the arc of the umbrella-shaped diffuser 211 and enters the filter screen device 31. The main filter layer 311 is connected to the support layer 312 and is installed on the filter frame 313. The filter frame 313 is connected to the shell 2 through a spring shock absorber 42. The shell 2 is provided with a groove 22 and a sealing gasket 23 to prevent the sulfur foam from leaking out. The electromagnetic vibrator 41 installed at the bottom of the filter frame 313 moves in conjunction with gravity to perform preliminary treatment on the sulfur foam, leaving impurities on the filter mechanism 3. After filtration, the sulfur foam flows into the heating chamber 51 through the guide device 54. A check valve 55 is installed to block steam. The heating chamber 51 indirectly heats the sulfur foam through heat transfer media such as steam and heat transfer oil. The other end of the heating chamber 51 is connected to the evaporation chamber 52. The heated sulfur foam enters the evaporation chamber 52. Due to the sudden drop in pressure, the water quickly vaporizes into steam. The two ends of the circulation mechanism 53 are connected to the heating chamber 51 and the evaporation chamber 52 respectively. The material at the bottom of the evaporation chamber 52 is extracted, reheated by the heating chamber 51, and sent back to the evaporation chamber 52 to form a closed loop. The bottom of the circulation mechanism 53 is provided with an outlet 531. The bottom outlet 531 of the circulation mechanism 53 is connected to the inlet of the thickener 6. The motor 64 drives the rotating shaft 63 to drive the stirring device 62 to rotate. The shearing force generated by stirring breaks the bubble film in the sulfur foam, promotes the release of the encapsulated water, and thickens the sulfur foam. The sulfur foam enters the discharge port 65 and the discharge is controlled by the regulating valve 66.
[0034] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
