Abstract
Description
Technical Field
[0001] This utility model relates to the field of desulfurization equipment technology, specifically a fuel ethanol desulfurization equipment. Background Technology
[0002] Fuel ethanol, as a gasoline additive, can increase the octane rating of gasoline. While the octane rating of automotive gasoline is typically required to be 90 or 93, ethanol can reach 111. Therefore, adding fuel ethanol to gasoline can significantly increase its octane rating, thereby improving the quality of vehicle exhaust and reducing pollution. Furthermore, ethanol has a better blending effect on the octane rating of alkane gasoline components than on olefin and aromatic gasoline components. Adding ethanol can also effectively improve the anti-knock properties of gasoline. The technology for producing fuel ethanol through non-grain brewing utilizes abundant coal gas from metallurgical industry exhaust as a carbon source, under suitable conditions... Sulfides are introduced into an aqueous solution at a certain temperature and pressure to ensure the utilization of sulfur by the microorganisms and to cultivate our company's unique microorganisms. Therefore, during this fermentation process, there is a possibility of excessive addition of sulfides, or the addition of sulfur in the gas pretreatment section may also introduce some sulfides. This causes some sulfur compounds to dissolve in the mash containing alcohol and accumulate in the finished fuel ethanol through distillation, thus affecting the quality of the fuel ethanol. The accumulation of sulfur in the fuel ethanol will create an acidic environment that damages the engine during long-term combustion, and the combustion product, sulfur dioxide, will pollute the environment.
[0003] This application improves upon existing technology, which typically uses activated carbon to absorb sulfides in fuel ethanol to achieve desulfurization. However, activated carbon has limited adsorption capacity and requires frequent disassembly, cleaning, and replacement. The disassembly and assembly of activated carbon in existing fuel ethanol desulfurization devices is cumbersome and reduces the processing efficiency of fuel ethanol. Utility Model Content
[0004] The purpose of this invention is to provide a fuel ethanol desulfurization device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fuel ethanol desulfurization device, comprising a first desulfurization tank and a second desulfurization tank. The top of the first desulfurization tank is fixedly equipped with an inlet pipe communicating with its interior. Second support rods are fixedly connected to both sides of the bottom of the first desulfurization tank. The bottom of the second support rods is fixedly connected to the second desulfurization tank. A first conduit communicating with its interior is fixedly connected to the center of the top of the second desulfurization tank. The first conduit is connected to the interior of the first desulfurization tank. Threaded grooves are provided on the left side of both the first and second desulfurization tanks. Hollow annular threaded blocks are threaded onto the inner wall of the threaded grooves. A tank cover is fixedly connected to the left side of the hollow annular threaded blocks. Hollow annular plates are fixedly connected to the right side of the interior of both the first and second desulfurization tanks. Annular grooves are provided on the surface of the hollow annular plates. An activated carbon adsorption mesh is movably disposed inside the annular grooves.
[0006] As a further embodiment of this utility model: a motor is installed on the right side of both the first desulfurization tank and the second desulfurization tank, and a rotating shaft is fixedly connected to the output end of the motor. Multiple stirring plates are fixedly arranged on the outer wall of the rotating shaft.
[0007] As a further embodiment of this utility model: a first support rod is fixedly connected to both sides of the bottom of the second desulfurization tank, a storage box is fixedly connected to the bottom of the first support rod, and a second conduit is fixedly installed on the top of the storage box and communicates with its interior, and the second conduit is connected to the interior of the second desulfurization tank.
[0008] As a further embodiment of this utility model: a carbon disulfide sensor is installed at the bottom of the storage tank, and a liquid outlet pipe connected to the inside of the storage tank is fixedly installed on the left side of the storage tank, with a drain valve installed inside the liquid outlet pipe.
[0009] As a further embodiment of this utility model: a suction pump is installed on the right side of the storage tank, and the input end of the suction pump is connected to the inside of the storage tank through a pipe. The output end of the suction pump is fixedly connected to a liquid guide pipe, and one end of the liquid guide pipe passes through the first desulfurization tank and extends into the inside of the first desulfurization tank.
[0010] As a further embodiment of this utility model: support blocks are fixedly connected to both sides of the bottom of the storage box, and a control panel is installed on the front end of the storage box.
[0011] This utility model has the following beneficial effects:
[0012] (1) Through the structural design of the first desulfurization tank, the second desulfurization tank, the activated carbon adsorption mesh barrel, the stirring plate, the rotating shaft, the motor, the hollow annular plate, the annular slot, the threaded slot, the tank cover and the hollow annular threaded block, it is possible to facilitate the disassembly, cleaning and replacement of the activated carbon adsorption mesh barrel, which can effectively improve the processing efficiency of fuel ethanol. At the same time, it is possible to facilitate the stirring of fuel ethanol in the first desulfurization tank and the second desulfurization tank, so that the fuel ethanol can have more sufficient contact with the activated carbon adsorption mesh barrel, thereby improving the desulfurization effect of fuel ethanol. This solves the problem that activated carbon is usually used to absorb sulfides in fuel ethanol to achieve the desulfurization effect, but due to the limited adsorption capacity of activated carbon, it needs to be disassembled, cleaned and replaced frequently. The existing fuel ethanol desulfurization device is troublesome to disassemble and install, which will reduce the processing efficiency of fuel ethanol.
[0013] (2) Through the structural design of the storage tank, outlet pipe, guide pipe, suction pump, drain valve and carbon disulfide sensor, after the fuel ethanol is desulfurized, it will enter the storage tank through the second conduit for temporary storage. At this time, the carbon disulfide sensor can be used to detect the content of sulfides in the fuel ethanol in the storage tank. When the content is lower than the standard value, the drain valve is opened and the fuel ethanol is discharged through the outlet pipe. When the content is higher than the standard value, the suction pump is started and the fuel ethanol is pumped back to the first desulfurization tank for desulfurization again. By making it easy to detect the desulfurized fuel ethanol, the desulfurization quality of the fuel ethanol can be guaranteed, thereby improving the practicality of the device.

[0024] Please see Figure 1-4This utility model provides an embodiment of a fuel ethanol desulfurization device, comprising a first desulfurization tank 1 and a second desulfurization tank 2. The top of the first desulfurization tank 1 is fixedly equipped with an inlet pipe 6 communicating with its interior. Second support rods 17 are fixedly connected to both sides of the bottom of the first desulfurization tank 1, and the bottom of the second support rods 17 is fixedly connected to the second desulfurization tank 2. A first conduit 10 communicating with its interior is fixedly connected to the center of the top of the second desulfurization tank 2, and the first conduit 10 is connected to the interior of the first desulfurization tank 1. Threaded grooves 22 are provided on the left side of both the first desulfurization tank 1 and the second desulfurization tank 2. Hollow annular threaded blocks 24 are threaded onto the inner wall of the threaded grooves 22, and a tank is fixedly connected to the left side of the hollow annular threaded blocks 24. Cover 23, hollow annular plates 18 are fixedly connected to the right side of the first desulfurization tank 1 and the second desulfurization tank 2. The surface of the hollow annular plate 18 is provided with an annular groove 21. An activated carbon adsorption mesh 11 is movably arranged inside the annular groove 21. Motors 16 are installed on the right side of the first desulfurization tank 1 and the second desulfurization tank 2. A rotating shaft 15 is fixedly connected to the output end of the motor 16. Multiple stirring plates 14 are fixedly arranged on the outer wall of the rotating shaft 15. First support rods 12 are fixedly connected to both sides of the bottom of the second desulfurization tank 2. A storage box 3 is fixedly connected to the bottom of the first support rod 12. A second conduit 19 is fixedly arranged on the top of the storage box 3 and communicates with its interior. The second conduit 19 is connected to the interior of the second desulfurization tank 2.
[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during use, the activated carbon adsorption mesh 11 inside the first desulfurization tank 1 and the second desulfurization tank 2 can absorb sulfides in fuel ethanol multiple times, thereby improving the desulfurization effect. After a period of time, the activated carbon adsorption mesh 11 can be disassembled by rotating the tank cover 23 until the hollow annular threaded block 24 disengages from the threaded groove 22. Then, the activated carbon adsorption mesh 11 can be pulled until it disengages from both the first desulfurization tank 1 and the second desulfurization tank 2, thus completing the disassembly of the activated carbon adsorption mesh 11. Similarly, with the hollow annular plate 18 and the threaded groove 22, the activated carbon adsorption mesh 11 can be easily installed. By facilitating the disassembly, cleaning, and replacement of the activated carbon adsorption mesh 11, the processing efficiency of fuel ethanol can be effectively improved. The desulfurization efficiency is improved by using a motor 16 to drive a rotating shaft 15 to rotate during the flow of fuel ethanol through the first desulfurization tank 1 and the second desulfurization tank 2. The rotating shaft 15 drives the stirring plate 14 to rotate, which in turn stirs the fuel ethanol in the first desulfurization tank 1 and the second desulfurization tank 2. This allows the fuel ethanol to come into more thorough contact with the activated carbon adsorption mesh 11, thereby improving the desulfurization effect of the fuel ethanol. This solves the problem that while activated carbon is usually used to absorb sulfides in fuel ethanol to achieve desulfurization, its limited adsorption capacity requires frequent disassembly, cleaning, and replacement. The existing fuel ethanol desulfurization devices are cumbersome to disassemble and install, which reduces the processing efficiency of fuel ethanol.
[0026] A carbon disulfide sensor 20 is installed at the bottom of the storage tank 3. A liquid outlet pipe 4 connected to the inside of the storage tank 3 is fixedly installed on the left side of the storage tank 3. A drain valve 13 is installed inside the liquid outlet pipe 4. A suction pump 8 is installed on the right side of the storage tank 3. The input end of the suction pump 8 is connected to the inside of the storage tank 3 through a pipe. A liquid guide pipe 7 is fixedly connected to the output end of the suction pump 8. One end of the liquid guide pipe 7 passes through the first desulfurization tank 1 and extends into the inside of the first desulfurization tank 1. Support blocks 5 are fixedly connected to both sides of the bottom of the storage tank 3. A control panel 9 is installed on the front side of the storage tank 3.
[0027] Specifically, such as Figure 1 and Figure 2 As shown, during use, after the fuel ethanol is desulfurized, it enters the storage tank 3 through the second conduit 19 for temporary storage. At this time, the carbon disulfide sensor 20 can be used to detect the sulfide content in the fuel ethanol in the storage tank 3. When the content is lower than the standard value, the drain valve 13 is opened and the fuel ethanol is discharged through the outlet pipe 4. When the content is higher than the standard value, the suction pump 8 is started and the fuel ethanol is pumped back to the first desulfurization tank 1 for desulfurization again. By facilitating the detection of the desulfurized fuel ethanol, the desulfurization quality of the fuel ethanol can be guaranteed, thereby improving the practicality of the device.
[0028] Working Principle: In this application, when desulfurization of fuel ethanol is required, an appropriate amount of fuel ethanol is poured into the first desulfurization tank 1 through the inlet pipe 6. At this time, the fuel ethanol will pass through the first desulfurization tank 1, the first conduit 10, the second desulfurization tank 2, and the second conduit 19, and finally fall into the storage tank 3. During this process, the activated carbon adsorption mesh 11 inside the first and second desulfurization tanks 1 and 2 can absorb the sulfides in the fuel ethanol multiple times, thereby improving the desulfurization effect. During this process, the output end of the motor 16 can drive the rotating shaft 15 to rotate, and the rotating shaft 15 can drive the stirring plate 14 to rotate. The rotating stirring plate 14 can agitate the fuel ethanol in the first and second desulfurization tanks 1 and 2, so that the fuel ethanol can come into more sufficient contact with the activated carbon adsorption mesh 11, thereby improving the desulfurization effect of the fuel ethanol. Secondly, after a period of time, the tank cover 23 can be rotated until the hollow annular threaded block 24 is discharged from the tank. The activated carbon adsorption screen 11 is disengaged from the threaded groove 22, and then pulled until it detaches from both the first desulfurization tank 1 and the second desulfurization tank 2, thus completing the disassembly of the activated carbon adsorption screen 11. Similarly, with the hollow annular plate 18 and the threaded groove 22, the activated carbon adsorption screen 11 can be easily installed. By facilitating the disassembly, cleaning, and replacement of the activated carbon adsorption screen 11, the processing efficiency of fuel ethanol can be effectively improved. Finally, after the fuel ethanol desulfurization is completed, it will enter the storage tank through the second conduit 19. The fuel ethanol is temporarily stored in tank 3. At this time, the carbon disulfide sensor 20 can be used to detect the sulfide content in the fuel ethanol in tank 3. When the content is lower than the standard value, the drain valve 13 is opened and the fuel ethanol is discharged through the outlet pipe 4. When the content is higher than the standard value, the suction pump 8 is started and the fuel ethanol is pumped back to the first desulfurization tank 1 for desulfurization again. By facilitating the detection of the desulfurized fuel ethanol, the desulfurization quality of the fuel ethanol can be guaranteed, thereby improving the practicality of the device.
