Description

Technical Field

[0001] This utility model relates to the field of triphenylphosphine technology, and more specifically, to a triphenylphosphine wastewater treatment device. Background Technology

[0002] Triphenylphosphine is the most important of the triarylphosphine species. The pure product is a white crystalline solid and is widely used in organic synthesis. It is an important ligand for homogeneous catalysts used in modern petrochemical and fine chemical production, such as Wilkinson catalysts for homogeneous catalytic hydrogenation of olefins and Vittisch reagents used in fine chemicals. Moreover, new applications are constantly being developed, and the demand is increasing year by year.

[0003] Currently, a method for producing triphenylphosphine using toluene as an intermediate has emerged, which improves product yield. However, the production process generates wastewater containing toluene. Since toluene is toxic, it needs to be treated. Traditional methods for treating toluene-containing wastewater include biological and physical methods. Biological methods require the input of large amounts of biological agents, resulting in high costs. Physical methods mainly involve membrane treatment, which not only requires the input of a large number of permeate membranes but also necessitates regular membrane replacement. The high concentration of toluene in the concentrate also requires subsequent treatment. The treatment is not thorough, inconvenient, and inefficient, and further improvements are needed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a triphenylphosphine wastewater treatment device, which has the advantages of simple structure, high efficiency, and no residue, thereby solving the problems mentioned in the background technology.

[0006] (II) Technical Solution

[0007] To achieve the advantages of simple structure, high efficiency, and no residue, the specific technical solution adopted by this utility model is as follows: A triphenylphosphine wastewater treatment device includes a treatment tank and a shaft tube. One end of the treatment tank is rotatably connected to the shaft tube, which is rotatably connected to the treatment tank end via a sealed bearing. An atomizing nozzle is connected through the surface of the shaft tube to improve the dispersion of the wastewater during spraying. An ozone delivery pipe is connected through the other end of the treatment tank, and the other end of the ozone delivery pipe is connected to an ozone pumping device (a common device, not shown in detail in the figure). A diversion pipe is connected through the other end of the ozone delivery pipe. Multiple diversion pipes are arranged, and both ends of the diversion pipe are connected through... The system includes multiple sets of nozzles, each with an air outlet. A water pump is connected to the bottom of the treatment tank, with a circulation pump connected to the other end. A return pipe is connected to the output of the circulation pump, forming a common water circulation structure. The return pipe is rotatably connected to the shaft tube via a water-use rotary connector, a common device used for water circulation without affecting the shaft tube's rotation. A drive motor is fixedly connected to one end of the treatment tank, with a drive gear mounted on its output. A driven gear is fixedly mounted on the surface of the shaft tube, meshing with the drive gear, forming a common drive structure.

[0008] Furthermore, an exhaust pipe is connected to the top surface of the processing box, and the exhaust pipe is connected to the factory's exhaust equipment.

[0009] Furthermore, a drain pipe is connected through the bottom of the treatment tank, and a valve is installed on the surface of the drain pipe to facilitate the staff to open and discharge the treated wastewater inside the treatment tank.

[0010] Furthermore, the atomizing nozzles are arranged in multiple sets at equal intervals, and the atomizing nozzles are at equal angles along the central axis of the tube. The multiple sets of evenly distributed atomizing nozzles improve the uniformity of spraying and work efficiency.

[0011] Furthermore, the air outlets are distributed in multiple sets at equal intervals, and the air outlets are located outside the atomizing nozzle. The multiple sets of evenly distributed air outlets improve the ozone emission efficiency.

[0012] Furthermore, a wastewater inlet is connected to one end of the top surface of the treatment tank, and a sealing cap is spirally fitted onto the top surface of the wastewater inlet. Wastewater is fed into the treatment tank through the wastewater inlet. During ozone treatment, the wastewater inlet is sealed by the sealing cap to prevent gas leakage.

[0013] Furthermore, an online pH meter is installed on the surface of the treatment tank, and a pH display for use with the online pH meter is fixedly installed on the surface of the treatment tank. The probe of the online pH meter extends into the wastewater to detect the pH value of the wastewater. The staff can observe the value through the pH display. When the pH value is close to neutral, it means that the acidic substances in the intermediate products of the wastewater have been basically oxidized, and the final products are water and a small amount of water-soluble carbon dioxide. Then the valve can be opened to discharge the treated wastewater.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a triphenylphosphine wastewater treatment device, which has the following beneficial effects:

[0016] (1) This utility model is equipped with an ozone delivery pipe and a circulation pump. When treating the toluene-containing wastewater generated during the production of triphenylphosphine, the toluene-containing wastewater can be put into the treatment tank first, and ethanol can be added as an organic solvent. Then, the circulation pump is started, and the circulation pump pumps the toluene-containing wastewater into the shaft pipe and sprays it out along the atomizing nozzle. At the same time, ozone is introduced into the ozone delivery pipe, and the ozone is blown out along the gas outlet and comes into contact with the atomized toluene-containing wastewater. Through the strong oxidation effect of ozone, the toluene in the toluene-containing wastewater is gradually oxidized and decomposed into carbon dioxide and water. Carbon dioxide and excess ozone are discharged along the exhaust pipe. Since carbon dioxide and ozone are both part of the air, they will not cause air pollution. The final product water will not cause pollution. Finally, it is treated into a pollution-free product with no harmful residues. Through the circulation action of the circulation pump, the toluene-containing wastewater is subjected to multiple strong oxidations to remove intermediate products, further avoiding intermediate product residues. The treatment is thorough and efficient. Compared with the traditional biological method and membrane treatment method, this application has less residue, thorough treatment, low cost, rapid reaction and high working efficiency.

[0017] (2) The present invention is equipped with a shaft tube. During the treatment, the drive motor drives the drive gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the shaft tube to rotate. The rotation of the shaft tube drives the atomizing nozzle to rotate, so that it forms an all-round spray, which expands the distribution range of toluene-containing wastewater, further improves the reaction efficiency with ozone, and thus further improves the oxidation efficiency and the treatment efficiency.

Figure 1-4As shown, the triphenylphosphine wastewater treatment device according to an embodiment of this utility model includes a treatment tank 1 and a shaft tube 7. One end of the treatment tank 1 is rotatably connected to the shaft tube 7, which is rotatably connected to one end of the treatment tank 1 via a sealed bearing. An atomizing nozzle 8 is connected through the surface of the shaft tube 7, which improves the dispersion of the wastewater during spraying. The other end of the treatment tank 1 is connected to an ozone delivery pipe 2, which is connected to an ozone pumping device (a common device, not shown in detail in the figure).

The treatment tank 1 is connected to a nozzle 4, with multiple sets of nozzles 4 arranged. Each nozzle 4 has an air outlet 5, also with multiple sets of outlets 5. A water suction pipe 17 is connected through the bottom of the treatment tank 1, and a circulation pump 16 is connected to the other end of the water suction pipe 17. A return pipe 14 is connected to the output end of the circulation pump 16, forming a common water circulation structure.

The water-use rotary connector 13 is a common device used for the rotatable connection of water without affecting the rotation of the shaft tube 7. A drive motor 10 is fixedly connected to one end of the treatment tank 1, and the output end of the drive motor 10... A drive gear 11 is installed, and a driven gear 12 is fixedly installed on the surface of the shaft tube 7, with the driven gear 12 meshing with the drive gear 11. This is a common drive structure. When treating toluene-containing wastewater generated during the production of triphenylphosphine, the toluene-containing wastewater can first be added to the treatment tank 1, with ethanol added as an organic solvent. Then, the circulation pump 16 is started, pumping the toluene-containing wastewater into the shaft tube 7, where it is sprayed out along the atomizing nozzle 8. Simultaneously, ozone is introduced through the ozone delivery pipe 2, and the ozone is blown out through the outlet 5, contacting the atomized toluene-containing wastewater. Through the strong oxidizing effect of the ozone, the toluene-containing wastewater... Toluene in the water is gradually oxidized and decomposed into carbon dioxide and water. Carbon dioxide and excess ozone are discharged through exhaust pipe 6. Since carbon dioxide and ozone are both part of the air, they will not cause air pollution. The final product, water, will not cause pollution either. It is ultimately treated into a pollution-free product with no harmful residues. Through the circulation of pump 16, the toluene-containing wastewater is subjected to multiple strong oxidation processes to remove intermediate products, further avoiding intermediate product residues. The treatment is thorough and efficient. Compared with traditional biological and membrane treatment methods, this application has less residue, more thorough treatment, lower cost, faster reaction, and higher working efficiency.

[0028] In one embodiment, an exhaust pipe 6 is connected through the top surface of the processing box 1, and the exhaust pipe 6 is connected to the factory's exhaust equipment.

[0029] In one embodiment, a drain pipe 18 is connected through the bottom surface of the treatment tank 1, and a valve is installed on the surface of the drain pipe 18 to facilitate the staff to open and discharge the treated wastewater inside the treatment tank 1.

[0030] In one embodiment, multiple sets of atomizing nozzles 8 are arranged at equal intervals, and the atomizing nozzles 8 are at equal angles along the central axis of the shaft tube 7. The multiple sets of evenly distributed atomizing nozzles 8 improve the uniformity of spraying and working efficiency. During treatment, the drive motor 10 drives the drive gear 11 to rotate, which in turn drives the driven gear 12 to rotate, which in turn drives the shaft tube 7 to rotate. The rotation of the shaft tube 7 drives the atomizing nozzles 8 to rotate, so that it forms an all-round spray, expands the distribution range of toluene-containing wastewater, further improves the reaction efficiency with ozone, and thus further improves the oxidation efficiency and treatment efficiency.

[0031] In one embodiment, multiple sets of air outlets 5 are evenly distributed, and the air outlets 5 are located outside the atomizing nozzle 8. The multiple sets of evenly distributed air outlets 5 improve the ozone emission efficiency.

[0032] In one embodiment, a wastewater inlet 9 is connected to one end of the top surface of the treatment tank 1, and a sealing cap is spirally fitted on the top surface of the wastewater inlet 9. Wastewater is fed into the treatment tank 1 through the wastewater inlet 9. During ozone treatment, the wastewater inlet 9 is sealed by the sealing cap to prevent gas leakage.

[0033] In one embodiment, an online pH meter 15 is installed on the surface of the treatment tank 1, and a pH display 19 for use with the online pH meter 15 is fixedly installed on the surface of the treatment tank 1. The probe of the online pH meter 15 extends into the wastewater to detect the pH value of the wastewater. The staff can observe the value through the pH display 19. When the pH value is close to neutral, it means that the acidic substances in the intermediate products of the wastewater have been basically oxidized, and the final products are water and a small amount of water-soluble carbon dioxide. Then the valve can be opened to discharge the treated wastewater.

[0034] Working Principle: When treating toluene-containing wastewater generated during the production of triphenylphosphine, the wastewater is first placed in treatment tank 1, with ethanol added as an organic solvent. Then, circulation pump 16 is started, pumping the wastewater into the shaft pipe 7, where it is sprayed out through atomizing nozzles 8. Simultaneously, ozone is introduced through ozone delivery pipe 2, and the ozone is blown out through outlet 5, contacting the atomized toluene-containing wastewater. Through the strong oxidizing effect of ozone, the toluene in the wastewater is gradually oxidized and decomposed into carbon dioxide and water. Carbon dioxide and excess ozone are discharged through exhaust pipe 6. Since carbon dioxide and ozone are both part of the air, they do not cause air pollution, and the final product, water, does not cause pollution. The wastewater is thus treated to produce... The process produces no polluting byproducts and leaves no harmful residues. Through the circulation of the circulating pump 16, the toluene-containing wastewater undergoes multiple strong oxidation processes to remove intermediate products, further preventing intermediate product residues. The treatment is thorough and efficient. Compared to traditional biological and membrane treatment methods, this application results in less residue, more thorough treatment, lower cost, faster reaction, and higher work efficiency. During treatment, the drive motor 10 drives the drive gear 11 to rotate, which in turn drives the driven gear 12 to rotate, which in turn drives the shaft tube 7 to rotate. The rotation of the shaft tube 7 drives the atomizing nozzle 8 to rotate, forming an all-round spray, expanding the distribution range of the toluene-containing wastewater, further improving the reaction efficiency with ozone, thereby further improving the oxidation efficiency and treatment efficiency.
