Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and specifically discloses a temperature-controlled reaction device for glow pyrolysis sewage treatment. Background Art

[0002] Glow pyrolysis is a technology that uses the plasma generated by glow discharge to decompose compounds, that is, a high voltage is applied in a low-pressure gas to generate plasma, and the high-energy electrons and active particles in the plasma decompose the compounds into smaller molecules or atoms. Therefore, glow pyrolysis is commonly used in environmental engineering to treat harmful gases and wastewater. The advantages of glow pyrolysis are high efficiency, pyrolysis can be achieved at a relatively low temperature, secondly it is controllable, and the pyrolysis process can be controlled by adjusting the discharge parameters; furthermore, it is environmentally friendly and can reduce secondary pollution.

[0003] The invention disclosed in the publication number: CN118405740B discloses a multifunctional composite sewage treatment and purification device, including a placement table and a reaction chamber, and also includes a purification device; wherein, the purification device includes a purification box, a diversion frame, a fixing rod, a sleeve, a wind baffle, a diversion plate and a liquid storage frame. The purification box is fixedly installed above the reaction chamber, the diversion frame is fixedly installed below the purification box, an air inlet is opened below the diversion frame, the fixing rod is fixedly installed on the surface of the air inlet, the sleeve is rotatably installed on the surface of the fixing rod, and the wind baffle is fixedly installed on the surface of the sleeve; although this invention can avoid the excessive flow rate of harmful gases, it lacks a temperature control component and is not suitable for the technical means that will generate heat release during the purification treatment of sewage, nor is it suitable for the method of using glow pyrolysis reaction to treat sewage. Since the glow pyrolysis reaction process is a continuous heat release process, too high a temperature will seriously affect the reaction efficiency of glow pyrolysis, that is, it will cause incomplete pyrolysis of harmful macromolecules in the sewage, resulting in incomplete sewage purification. Therefore, temperature control is the key during the process of using glow pyrolysis to treat sewage. Therefore, when using this device for glow pyrolysis to treat sewage, it shows great deficiencies;

[0004] However, at present, the temperature control device for glow pyrolysis sewage treatment generally uses a water-cooled jacket for temperature control. However, the water-cooled jacket temperature control has the disadvantage of too long heat conduction path, slow temperature exchange rate, resulting in too large axial temperature difference in the reaction chamber and local overheating; however, local overheating in the reaction chamber will trigger a series of chain reactions, seriously affecting the equipment safety and reaction efficiency, and at the same time causing damage to the equipment, further increasing the cost of equipment maintenance and repair. Therefore, it is crucial to control the temperature in the reaction chamber within a reasonable range and minimize the axial temperature difference in the reaction chamber. Summary of the Invention

[0012] Preferably, the water-cooled sleeve is of a spiral structure. A pipe rack for fixing the water-cooled sleeve is installed on the water-cooled sleeve. The water-cooled sleeve is communicated with a second water inlet pipe and a second water outlet pipe. The water-cooled sleeve is communicated with a centrifugal pump through the second water inlet pipe. A second solenoid valve is installed on the second water outlet pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By arranging an isolation cover, the present invention can isolate the cooling chamber from the staff, avoiding direct contact between the staff and the rotating cooling chamber, preventing unnecessary accidents, ensuring the safety of the staff, improving the safety of the equipment, and taking precautions; at the same time, the heat dissipation holes opened on the circumferential surface of the isolation cover are beneficial to the heat dissipation of the cooling chamber itself, helping to improve the temperature exchange rate in the cooling chamber, thereby accelerating the reduction of the temperature in the reaction chamber and keeping it within a reasonable temperature range, enhancing the temperature control effect of the device;

[0020] 3. The present invention realizes that when the temperature in the reaction chamber is too high, the rotation speed of the cooling chamber increases, and the speed of the centrifugal pump injecting cold water into the water-cooled sleeve also increases accordingly, thereby increasing the speed of temperature drop in the reaction chamber, accelerating the temperature exchange between the reaction chamber, the cooling chamber and the water-cooled sleeve, and reducing the temperature in the reaction chamber to a reasonable range. When the temperature in the reaction chamber is moderate, the rotation speed of the cooling chamber slows down, and the speed of the centrifugal pump injecting cold water into the water-cooled sleeve also slows down, so that the temperature in the reaction chamber is always controlled within a reasonable range. Therefore, it has a very broad application prospect by setting an arc gear mechanism, a dual-axis motor, a planar spiral gear mechanism and a centrifugal pump, and making their rotation speeds synchronized through a PLC control cabinet, and being electrically connected to a temperature sensor.

On the inner peripheral surface of the cooling chamber 3, stirring plates 4 for agitating the water flow and accelerating its cooling are arranged obliquely and staggeredly. There are six stirring plates 4. Through holes 16 for the water flow to pass through are formed on the stirring plates 4.

A first solenoid valve 23 is installed on the first water inlet pipe 12. An ultrasonic water level detector 28 is arranged at a position of the first water inlet pipe 12 close to the top of the cooling chamber 3 for monitoring the water level within the cooling chamber 3 to avoid the overflow of excessive cold water from the cooling chamber 3.

[0036] Within the cooling chamber 3, a reaction chamber 5 for glow pyrolysis of sewage is rotatably connected by a support pipe 22. The bottom of the reaction chamber 5 is fixedly and tightly connected to the support pipe 22 by welding. A third water outlet pipe 21 is connected in communication with the bottom of the reaction chamber 5. The diameter size of the third water outlet pipe 21 is smaller than the diameter size of the support pipe 22, and the height size of the third water outlet pipe 21 is greater than the height size of the support pipe 22. The third water outlet pipe 21 is arranged within the support pipe 22. A third solenoid valve 25 is installed at the end position of the third water outlet pipe 21 away from the reaction chamber 5.

[0037] A water-cooled sleeve 6 for temperature control is fixedly installed within the reaction chamber 5. The water-cooled sleeve 6 has a spiral structure. A pipe support 18 for fixing the water-cooled sleeve 6 is installed on the water-cooled sleeve 6. An inlet and an outlet are formed on the water-cooled sleeve 6. The inlet is arranged at the bottom of the water-cooled sleeve 6, and the outlet is arranged at the top of the water-cooled sleeve 6. The water-cooled sleeve 6 is connected in communication with a second water inlet pipe 19 through the inlet, and the water-cooled sleeve 6 is connected in communication with a second water outlet pipe 20 through the outlet. A second solenoid valve 24 is installed on the second water outlet pipe 20.

[0038] A temperature sensor 27 for monitoring the temperature in the reaction chamber 5 is disposed on the top of the reaction chamber 5; a reaction chamber cover 17 is installed on the top of the reaction chamber 5, and the reaction chamber cover 17 includes a cover seat 1701 that is fastened to the top of the reaction chamber 5, and a support 1702 is installed on one side of the circumference of the cover seat 1701, and the support 1702 is rotatably connected to one end of a support arm 1703 through a rotating shaft, and a pin seat 1704 is arranged at the other end of the support arm 1703, and a groove 1705 for clamping and fixing is opened on the pin seat 1704, and a connecting column 1706 is installed at the bottom of the support arm 1703. The connecting column 1706 is fastened to the cover body 1707, and the shaft seat 1708 is installed on the other side of the circumference of the cover seat 1701. A pin 1709 for controlling the opening and closing of the cover body 1707 is rotatably connected to the shaft seat 1708 through a rotating shaft. The pin 1709 is a cylindrical structure, and a handle 1710 for easy grasping is provided on the top of the pin 1709. The handle 1710 is a semicircular structure, and the pin 1709 is clamped with the pin seat 1704 through a groove 1705. The staff can open the reaction chamber cover 17 to pour the sewage that needs to be glow cracking treatment into the reaction chamber 5.

[0039] The end of the transmission shaft 7 away from the isolation cover 2 is sleeved with an arc gear mechanism 8, and the arc gear mechanism 8 is transmission-connected with the first rotating shaft of the dual-axis motor 9; the arc gear mechanism 8 includes an arc gear 801 sleeved with the transmission shaft 7, and the arc gear 801 has gear teeth only on the lower bottom surface, and the arc gear 801 is meshed with a bevel gear 802, and the bevel gear 802 is fixedly connected with a first gear shaft 803, and the first gear shaft 803 is rotationally connected to the first rotating shaft of the dual-axis motor 9; therefore, the first rotating shaft of the dual-axis motor 9 rotates to make the first rotating shaft of the dual-axis motor 9 rotate. A gear shaft 803 rotates, and at the same time, the bevel gear 802 fixedly connected to the first gear shaft 803 rotates, thereby causing the circular arc gear 801 to rotate, and then the transmission shaft 7 connected to the circular arc gear 801 rotates. When the transmission shaft 7 rotates, the cooling bin 3 fastened thereto also rotates, so that the stirring plate 4 in the cooling bin 3 rotates, stirring the cold water in the cooling bin 3, so that the water flow speed in the cooling bin 3 increases, thereby accelerating the rate of temperature exchange between the cold water in the cooling bin 3 and the reaction bin 5, so that the temperature in the reaction bin 5 is quickly reduced to a reasonable range.

[0040] Among them, the height dimension of the isolation cover 2 is greater than the height dimensions of the cooling bin 3 and the reaction bin 5, which can isolate the cooling bin 3 from the staff to prevent accidents caused by the rotation of the cooling bin 3; the height dimension of the cooling bin 3 is smaller than the height dimension of the reaction bin 5, which can prevent the water flow in the cooling bin 3 from submerging the reaction bin 5, thereby avoiding damage to the equipment and water backflow into the reaction bin 5, affecting the glow cracking treatment of wastewater.

[0041] The arc gear mechanism 8 is drivingly connected to a planar spiral gear mechanism 10 through the second rotating shaft of a dual-axis motor 9. The planar spiral gear mechanism 10 is rotatably connected to a centrifugal pump 11. The centrifugal pump 11 is communicated with the water-cooling sleeve 6 through a second water inlet pipe 19. Among them, the planar spiral gear mechanism 10 includes a second gear shaft 1001 rotatably connected to the second rotating shaft of the dual-axis motor 9. A planar spiral gear 1002 is installed at the end of the second gear shaft 1001. The teeth of the planar spiral gear 1002 are arranged in a planar spiral shape, and the teeth of the planar spiral gear 1002 include two endpoints, namely, a driving end and a driven end. The rotation radius of the driving end is larger than that of the driven end. The planar spiral gear 1002 is conjugately connected to a transmission gear 1003. The transmission gear 1003 is sleeved with a third gear shaft 1004. The third gear shaft 1004 is connected to the rotating shaft of the centrifugal pump 11. When the planar spiral gear 1002 rotates, the driving end of the teeth is arranged in the gap between two adjacent teeth of the transmission gear 1003. This is the initial state. Immediately afterwards, the planar spiral gear 1002 rotates, causing the driven end to rotate and be arranged in the next adjacent gap of the transmission gear 1003. Subsequently, when rotating again, the driving end is arranged in the gap between two adjacent teeth of the transmission gear 1003 again, that is, returning to the initial state. According to the above movement track, the rotation of the planar spiral gear 1002 can drive the rotation of the transmission gear 1003, and at the same time make the rotating shaft of the centrifugal pump 11 rotate, so that the centrifugal pump 11 pumps cold water into the water-cooling sleeve 6.

[0042] Among them, the centrifugal pump 11, the water extraction pump 14, the dual-axis motor 9, the first solenoid valve 23, the second solenoid valve 24, the third solenoid valve 25, as well as the temperature sensor 27 and the ultrasonic water level detector 28 are all electrically connected to a PLC control cabinet 26. When the temperature in the reaction chamber 5 rises, the temperature sensor 27 monitors it and sends an electrical signal to the PLC control cabinet 26. Subsequently, the dual-axis motor 9 is started. The rotation speeds of the two rotating shafts of the dual-axis motor 9 can be adjusted according to the temperature monitored by the temperature sensor 27. When the temperature sensor 27 monitors that the temperature in the reaction chamber 5 is too high, the rotation speed of the dual-axis motor 9 increases. When the temperature sensor 27 monitors that the temperature in the reaction chamber 5 decreases, the rotation speed of the dual-axis motor 9 slows down.

[0043] The startup of the biaxial motor 9 causes the arc gear mechanism 8 and the planar spiral gear mechanism 10 to operate simultaneously. At this time, the cooling bin 3 rotates following the operation of the arc gear mechanism 8, causing the cold water in the cooling bin 3 to rotate. Meanwhile, with the agitation of the stirring plate 4, the heat exchange in the reaction chamber 5 is accelerated, reducing the temperature in the reaction chamber 5. At the same time, the operation of the planar spiral gear mechanism 10 causes the centrifugal pump 11 to continuously inject cold water into the water-cooled sleeve 6 through the second water inlet pipe 19. The spiral structure of the water-cooled sleeve 6 can make the heat exchange in the reaction chamber 5 more uniform, reducing the axial temperature difference in the reaction chamber 5 and making the glow pyrolysis reaction more complete. By cooperating the cooling bin 3 and the water-cooled sleeve 6 to exchange the temperature in the reaction chamber 5, the temperature in the reaction chamber 5 can be evenly and rapidly reduced to a reasonable range, avoiding the phenomena of excessive local temperature and excessive axial temperature difference. Therefore, it has a very broad application prospect.

[0044] The working principle of the present invention is as follows:

[0045] First, the staff grasps the handle 1710, causing the pin shaft 1709 to rotate within the shaft seat 1708. At the same time, the pin shaft 1709 is disengaged from the groove 1705 of the pin seat 1704. Meanwhile, the support arm 1703 rotates within the support 1702, causing the cover body 1707 to disengage from the cover seat 1701, thus opening the reaction chamber cover 17. Then, the sewage to be subjected to glow pyrolysis treatment is poured into the reaction chamber 5. After pouring is completed, the reaction chamber cover 17 is closed again. Subsequently, the first solenoid valve 23 is opened, and cold water is injected into the cooling bin 3 through the first water inlet pipe 12. When the ultrasonic water level detector 28 monitors that the water level reaches the preset standard, the ultrasonic water level detector 28 sends an electrical signal to the PLC control cabinet 26, and the first solenoid valve 23 closes, stopping the injection of cold water into the cooling bin 3.

[0046] Subsequently, a glow pyrolysis reaction occurs in the reaction chamber 5 to treat the sewage. At this time, the temperature in the reaction chamber 5 begins to rise. When the temperature sensor 27 detects that the temperature is about to exceed the preset reasonable range, the temperature sensor 27 sends an electrical signal to the PLC control cabinet 26. The PLC control cabinet 26 controls the start and operation of the double-shaft motor 9. Subsequently, the first rotating shaft of the double-shaft motor 9 drives the first gear shaft 803 to rotate, and at the same time, the tapered gear 802 fixedly sleeved with it rotates. Immediately afterwards, the arc gear 801 rotates, causing the transmission shaft 7 fixedly sleeved with it to rotate. The rotation of the transmission shaft 7 causes the cooling chamber 3 to rotate, and the stirring plates 4 obliquely and staggeredly arranged on the inner wall of the cooling chamber 3 also rotate accordingly, thereby agitating the cold water in the cooling chamber 3 to exchange the temperature with the temperature in the reaction chamber 5. The agitation of the cold water in the cooling chamber 3 by the stirring plates 4 can accelerate the process of temperature exchange and quickly reduce the temperature in the reaction chamber 5. At the same time, through holes 16 for water flow to pass through are provided on the stirring plates 4. The setting of the through holes 16 can prevent the splashing of water during agitation and avoid the overflow of water from the cooling chamber 3. A baffle 30 is provided at the top of the cooling chamber 3, and the baffle 30 is also used to block the overflow of water from the cooling chamber 3 to prevent damage to the equipment caused by water overflow. After the cold water in the cooling chamber 3 has undergone temperature exchange for a period of time, the PLC control cabinet 26 turns on the water pump 14 and the first solenoid valve 23. The water pump 14 pumps the water that has undergone temperature exchange in the cooling chamber 3 through the first water outlet pipe 13 and fills new cold water through the first water inlet pipe 12 to start a new round of temperature exchange process.

[0047] Meanwhile, the second rotating shaft of the double-shaft motor 9 drives the operation of the planar spiral gear mechanism 10. The second rotating shaft of the double-shaft motor 9 causes the second gear shaft 1001 to rotate. Subsequently, the planar spiral gear 1002 fixedly connected to the second gear shaft 1001 rotates. The rotation of the planar spiral gear 1002 drives the transmission gear 1003 to rotate, causing the third gear shaft 1004 to rotate, thereby causing the rotating shaft of the centrifugal pump 11 connected to it to rotate, and the centrifugal pump 11 operates accordingly. At the same time, the second solenoid valve 24 is opened. Cold water enters from the water inlet of the centrifugal pump 11 and is pumped into the water-cooled sleeve 6 through the second water inlet pipe 19. Due to the opening of the second solenoid valve 24, the cold water can flow out from the second water outlet pipe 20 through the second solenoid valve 24, ensuring the fluidity of the cold water in the water-cooled sleeve 6, enabling continuous temperature exchange between the water-cooled sleeve 6 and the reaction chamber 5, accelerating the cooling process in the reaction chamber 5, and making it drop to a reasonable temperature range more quickly. At the same time, the spiral structure of the water-cooled sleeve 6 can make the temperature exchange in the reaction chamber 5 more uniform and reduce the axial temperature difference in the reaction chamber 5.

[0048] However, when the sewage in the reaction chamber 5 has completed the glow pyrolysis reaction, the third solenoid valve 25 is opened by the PLC control cabinet 26, so that the sewage in the reaction chamber 5 flows out from the third water outlet pipe 21 and enters the next operation process.

[0049] Furthermore, the temperature monitored by the temperature sensor 27 can be used to send an electrical signal to the PLC control cabinet to adjust the rotation speeds of the two rotating shafts of the dual-axis motor 9. When the temperature sensor 27 detects that the temperature in the reaction chamber 5 is too high, the rotation speed of the dual-axis motor 9 increases, the agitation rate of the cooling chamber 3 and the cold water in the cooling chamber 3 increases. At the same time, the speed of the centrifugal pump 11 pumping cold water into the water-cooled sleeve 6 increases, and the circulation frequency of the cold water in the water-cooled sleeve 6 increases. Thus, the temperature exchange in the reaction chamber 5 is accelerated. When the temperature sensor 27 detects that the temperature in the reaction chamber 5 drops to a reasonable range, the rotation speed of the dual-axis motor 9 slows down, the agitation rate of the cooling chamber 3 and the cold water in the cooling chamber 3 slows down. At the same time, the speed of the centrifugal pump 11 pumping cold water into the water-cooled sleeve 6 slows down, and the circulation frequency of the cold water in the water-cooled sleeve 6 slows down accordingly, which helps to keep the temperature in the reaction chamber 5 at the current state, thereby realizing temperature control, avoiding equipment damage caused by excessive local temperature and large axial temperature difference, and reducing the frequency and cost of equipment maintenance. Therefore, it has a very broad application prospect.
