Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, and more specifically, to a high-efficiency generator water recycling system. Background Technology

[0002] Acetylene is one of the most basic raw materials for organic chemical products. In my country, the calcium carbide process is the main method for producing acetylene gas. Traditional wet acetylene production technology consumes a large amount of water during the process, and unreacted water is also discharged along with the generated substances, resulting in a waste of water resources. Utility Model Content

[0003] This application provides a highly efficient generator water recycling system, which solves the problem of high water consumption and waste of water resources caused by the discharge of unreacted water along with the generated substances in the traditional wet acetylene production technology.

[0004] This application provides a high-efficiency generator water recycling system, including a generator and a filter press. The generator is connected to an overflow pipe via a pipeline. The outlet of the overflow pipe is connected to the slurry inlet of the filter press via a first pipeline. A drain pipe installed at the bottom of the filter press is connected to a saturated water tank. The saturated water tank is connected to a water pump via a pipeline. A water pump ball valve and a water pump check valve are installed on the pipeline between the water pump and the saturated water tank. The water pump is connected to the generator via a circulating water pipe. A slag discharge port at the bottom of the generator is connected to a slag discharge pipe, and a slag discharge valve is installed on the slag discharge pipe.

[0005] Preferably, the generator is equipped with a liquid level sensor.

[0006] Preferably, one end of the slag discharge pipe is connected to a sedimentation tank.

[0007] Preferably, the sedimentation tank is equipped with a stirring structure, which includes a stirring motor and stirring blades.

[0008] Preferably, a drain pipe is installed at the bottom of the sedimentation tank, and a drain ball valve is provided on the drain pipe.

[0009] Preferably, a slurry discharge pipe is installed at the bottom of the sedimentation tank, the slurry discharge pipe is connected to a mud pump, and the mud pump is connected to the filter press through a second pipe.

[0010] Preferably, a pneumatic ball valve and a check valve are installed on the slurry discharge pipe.

[0011] Preferably, the generator is equipped with a support base.

[0012] As can be seen from the above technical solution, this application provides a highly efficient generator circulating water system. Calcium carbide reacts with water in the generator to produce acetylene and calcium hydroxide. Calcium hydroxide, along with unreacted water, enters the overflow pipe through a pipeline. Utilizing the natural elevation difference, the concentrated slurry flows by gravity from the first pipeline to the belt filter, saving the pumping step. After filtration in the belt filter, the filtered slurry is discharged from the belt filter's slag discharge pipe, and the filtered water flows into the saturated water tank through the drain pipe. When the generator needs water replenishment, the water pump pumps water from the saturated water tank into the generator through the circulating water pipe, realizing the recycling of filtered water and saving water resources. When the liquid level in the generator is detected to be too high, the slag discharge valve is opened, allowing the concentrated slurry to be discharged from the slag discharge port at the bottom of the generator and discharged into the sedimentation tank through the slag discharge pipe. After sedimentation in the sedimentation tank, the concentrated slurry is discharged from the slurry discharge pipe and sent by the mud pump through the second pipeline to the belt filter for dewatering. Since calcium hydroxide is prone to deposit and scale, the stirring structure in the sedimentation tank is to prevent calcium hydroxide from accumulating and clogging the sedimentation tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, after the slurry generated by the generator reaction is dewatered and discharged by the filter press, the filtered water flows into the saturated water tank for storage. When water needs to be added during the reaction in the generator, the water pump pumps the filtered water into the generator through the circulating water pipe for recycling, thus preventing water waste.

[0015] 2. The overflow pipe in this utility model utilizes the natural elevation difference to allow the concentrated slurry to flow by gravity to the filter press, saving the pumping process and energy.

[0016] 3. This utility model sets the first pipe and the slag discharge pipe with a slope of 3 percent to prevent the calcium hydroxide generated in the generator from depositing in the pipe and clogging it.

[0017] 4. The stirring structure added to the sedimentation tank of this utility model is to facilitate the cleaning of the sedimentation tank and prevent calcium hydroxide from scaling in the stirring tank.

[0018] In summary, in a highly efficient generator water recycling system, the slurry generated by the generator reaction is dewatered and discharged through a filter press, and the filtered water flows into a saturated water tank for storage. When water is needed for the reaction in the generator, the water pump pumps the filtered water back into the generator through a circulating water pipe for recycling, preventing water waste. Furthermore, the added stirring structure in the sedimentation tank facilitates cleaning of the sedimentation tank and prevents calcium hydroxide from scaling in the stirring tank.

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] See Figure 1 This application proposes a highly efficient generator water recycling system to address the problems of high water consumption and waste caused by the discharge of unreacted water along with the generated substances in traditional wet acetylene production technology. The system involves dewatering and discharging the slurry produced by the generator reaction through a filter press, with the filtered water flowing into a saturated water tank for storage. When water is needed for the reaction in the generator, a water pump pumps the filtered water back into the generator through a circulating water pipe for recycling, preventing water waste. Furthermore, the addition of a stirring structure in the sedimentation tank facilitates cleaning and prevents calcium hydroxide from forming scale in the stirring tank.

[0025] Specifically, a high-efficiency generator water recycling system includes a generator 1 and a filter press 17. The generator 1 is connected to an overflow pipe 2 via a pipeline. The outlet of the overflow pipe 2 is connected to the slurry inlet 24 of the filter press 17 via a first pipeline 3. A drain pipe 18 installed at the bottom of the filter press 17 is connected to a saturated water tank 19. The saturated water tank 19 is connected to a water pump 20 via a pipeline. A water pump ball valve 21 and a water pump check valve 22 are installed on the pipeline between the water pump 20 and the saturated water tank 19. The water pump 20 is connected to the generator 1 via a circulating water pipe 23. A slag discharge port 4 at the bottom of the generator 1 is connected to a slag discharge pipe 6. A slag discharge valve 5 is installed on the slag discharge pipe 6. Calcium carbide and water react in the generator 1 to produce acetylene. Alkyne and calcium hydroxide, along with unreacted water, enter overflow pipe 2 through a pipe. Utilizing the natural elevation difference, the concentrated slurry flows by gravity from the first pipe 3 to the filter press 17, saving the pumping step. After filtration in the filter press 17, the filtered slurry is discharged from the filter press discharge pipe 25, and the filtered water flows into the saturated water tank 19 from the drain pipe 18. When the generator needs water replenishment, the water pump pumps water from the saturated water tank 19 into the generator 1 through the circulating water pipe 23, realizing the recycling of filtered water and saving water resources. The first pipe 3 and the discharge pipe 6 are set with a 3% slope to prevent the calcium hydroxide generated in the generator 1 from depositing in the pipes and clogging them.

[0026] The generator 1 is equipped with a liquid level sensor 26. One end of the slag discharge pipe 6 is connected to a sedimentation tank 7. The sedimentation tank 7 is equipped with a stirring structure, which includes a stirring motor 8 and stirring blades 9. A sludge discharge pipe 11 is installed at the bottom of the sedimentation tank 7, and a sludge discharge ball valve 10 is installed on the sludge discharge pipe 11. A slurry discharge pipe 12 is installed at the bottom of the sedimentation tank 7, and a mud pump 15 is connected to the mud pump 15. The mud pump 15 is connected to the filter press 17 through a second pipe 16. A pneumatic ball valve 13 and a check valve 14 are installed on the slurry discharge pipe 12. The liquid level sensor 26 on the generator 1 can detect the liquid level in the generator 1. When the liquid level in generator 1 is detected to be too high, the slag discharge valve 5 is opened, allowing the concentrated slurry to be discharged from the slag discharge port 4 at the bottom of generator 1 and discharged into the sedimentation tank 7 through the slag discharge pipe 6. After sedimentation in the sedimentation tank 7, the concentrated slurry is discharged from the slurry discharge pipe 12 and sent by the mud pump 15 through the second pipe 16 to the filter press 17 for dewatering. Since calcium hydroxide is prone to deposit and scale, the stirring structure in the sedimentation tank 7 is to prevent calcium hydroxide from accumulating and clogging in the sedimentation tank 7. A support base 27 is installed on generator 1, which serves to fix and support generator 1.

[0027] As can be seen from the above technical solution, a highly efficient generator water recycling system is implemented where calcium carbide reacts with water in generator 1 to produce acetylene and calcium hydroxide. The calcium hydroxide, along with unreacted water, enters overflow pipe 2 through a pipe. Utilizing the natural elevation difference, the concentrated slurry flows by gravity from the first pipe 3 to the filter press 17, eliminating the need for pumping. After filtration in the filter press 17, the filtered slurry is discharged from the filter press discharge pipe 25, and the filtered water flows from the drain pipe 18 into the saturated water tank 19. When the generator needs replenishment, a water pump fills the saturated water tank 19. Water is pumped into generator 1 through circulating water pipe 23 to achieve water recycling and save water resources. When the liquid level in generator 1 is detected to be too high, the slag discharge valve 5 is opened to discharge the concentrated slurry from the slag discharge port 4 at the bottom of generator 1 and into sedimentation tank 7 through slag discharge pipe 6. The concentrated slurry after sedimentation in sedimentation tank 7 is discharged from slurry discharge pipe 12 and sent to filter press 17 for dewatering by mud pump 15 through second pipe 16. Since calcium hydroxide is easy to deposit and form scale, the stirring structure in sedimentation tank 7 is to prevent calcium hydroxide from accumulating in sedimentation tank 7 and forming scale and blockage.
