Description

Technical Field

[0001] The invention relates to the field of wastewater distillation, and more particularly to a thiazole production wastewater distillation system. Background Art

[0002] Thiazole is a nitrogen-containing five-membered aromatic ring compound. Currently, thiazole and its derivatives are widely used in agriculture, chemistry, and drug development due to their unique chemical structure and properties. In the process of producing thiazole, the wastewater produced usually contains organic solvents and other harmful substances. At present, in order to reduce the damage of wastewater to the ecological environment and improve the utilization rate of organic solvents in wastewater, distillation equipment is usually used to distill the wastewater used in thiazole production;

[0003] In the process of equipment distilling waste water, the condenser is a key component in the distillation process. Its function is to condense steam into liquid, so as to realize the recovery and treatment of this part of liquid. After the condenser condenses the steam into liquid, although most of the liquid will flow into the collection container along the tube wall, a small part of the liquid will remain on the inner wall of the condenser to form water stains. When these water stains gradually accumulate and increase, they will affect the heat exchange efficiency of the tube wall, that is, it is easy to make the condensation efficiency of the condenser to the steam gradually reduce. Therefore, it is urgent to design a thiazole production wastewater distillation system to solve the above problems. Summary of the invention

[0056] See also Figures 1 to 17 A thiazole production wastewater distillation system comprises a distillation kettle body 1 and a liquid supply tank 2. A heating component 4 is arranged in the distillation kettle body 1, a pressure relief component 3 is arranged on the distillation kettle body 1, and a recovery component 8 is arranged on the liquid supply tank 2;

[0057] The heating assembly 4 comprises a cylinder 41 fixedly mounted in the distillation kettle body 1, a circulation assembly 5 is arranged in the cylinder 41, an annular slide groove 44 is provided on the cylinder 41, sliding blocks 45 evenly distributed in an annular shape are slidably mounted on the annular slide groove 44, a heating cylinder 42 is fixedly mounted between the sliding blocks 45, a stirring mechanism 48 is installed in the heating cylinder 42, and a scraping component is installed in the heating cylinder 42;

[0058] The recovery component 8 includes a heat-conducting pipe 85 fixedly connected to the distillation kettle body 1, and the heat-conducting pipe 85 is sealed and penetrates and is fixedly installed on the liquid supply box 2, a conduit 84 is fixedly connected between the heat-conducting pipe 85 and the distillation kettle body 1, a condensation component is installed between the heat-conducting pipe 85 cylinder body 41, and a cleaning mechanism 86 is installed in the heat-conducting pipe 85.

[0059] like Fig.11 , Fig.13As shown, a conveying assembly 6 is provided in the liquid supply box 2, and the conveying assembly 6 includes an air supply pipe 62 that is sealed and fixedly installed on the liquid supply box 2, and the rotating shaft 867 is rotatably connected to the inner wall of the air supply pipe 62, the air supply pipe 62 is fixedly connected with an air suction pipe 61, and one end of the air suction pipe 61 is sealed and fixedly installed on the liquid supply box 2, the cylinder 41 is fixedly connected with a water delivery pipe 63, and the heat conduction pipe 85 is sealed and fixedly installed on the water delivery pipe 63, and the water delivery pipe 63 is sealed and fixedly installed on the distillation kettle body 1 and the liquid supply box 2, the air suction pipe 61 and the water delivery pipe 63 are both fixedly connected with a connecting pipe 68, and pistons 69 are sealed and slidably installed in the two connecting pipes 68;

[0060] A servo motor 64 is fixedly installed on the liquid supply box 2, and a rotating shaft is fixedly installed on the driving end of the servo motor 64, and the rotating shaft seal passes through and is rotatably installed on the liquid supply box 2. A disc 65 is fixedly installed on the rotating shaft, and a circular shaft 67 is fixedly installed on the disc 65. A support rod is fixedly installed in the liquid supply box 2, and a push plate 66 is rotatably installed on the support rod. A square opening matching the circular shaft 67 is opened on the push plate 66, and a connecting piece 610 is installed between the two pistons 69 and the push plate 66.

[0061] Before using the equipment to distill wastewater for thiazole production, the wastewater to be distilled is first input into the internal buffer of the liquid supply tank 2, and then the servo motor 64 is started. The operation of the servo motor 64 will drive the push plate 66 to rotate and move through the cooperation of the rotating shaft, the disc 65, the circular shaft 67, and the square mouth. During the rotation and displacement of the push plate 66, the two pistons 69 can be driven to reciprocate relative motion through the cooperation with the two connecting parts 610.

[0062] The air suction pipe 61 and the water delivery pipe 63 are both equipped with a check valve and a delivery valve (not shown in the figure but not marked). Fig.13 As can be seen in FIG. 1 , the two valves at the bottom are check valves, and the two valves at the top are delivery valves). When the piston 69 at one side of the water delivery pipe 63 is forced to move to the left (as shown in FIG. 1 ), the piston 69 at one side of the water delivery pipe 63 is forced to move to the left (as shown in FIG. 1 ). Fig.13 The delivery valve in the water delivery pipe 63 is in a closed state. Therefore, the air pressure in the water delivery pipe 63, between the check valve and the delivery valve and the piston 69 will gradually decrease. During this process, the corresponding check valve will automatically open upward (as shown in FIG. Fig.13The water in the liquid supply tank 2 will be pumped into the water pipe 63 and the lower end of the delivery valve, and when the piston 69 on this side is forced to move to the right, the piston 69 will squeeze the water between the corresponding check valve and the delivery valve. During this process, the check valve is closed, and the delivery valve will be gradually opened, and the water entering the water pipe 63 will be squeezed to the upper end of the delivery valve. The above operation is then repeated to intermittently pump the waste water buffered in the liquid supply tank 2 into the cylinder 41. Similarly, when the piston 69 on one side of the air suction pipe 61 is forced to move back and forth left and right, the outside air can be intermittently sucked into the air suction pipe 61.

[0063] like Fig.11 , Fig.14 As shown, a filter assembly 7 is provided in the water pipe 63, and the filter assembly 7 includes an elastic ring 71 fixedly installed in the water pipe 63, a shaft rod is rotatably installed in the elastic ring 71, two shaft rods are provided, a filter screen 72 is fixedly installed between the two shaft rods, and the filter screen 72 is sealingly rotatably installed in the elastic ring 71, a knocking plate 73 is fixedly installed on the filter screen 72, a knocking ball 74 is fixedly installed in the elastic ring 71, a blocking plate 75 is fixedly installed in the elastic ring 71, a discharge pipe 76 is fixedly connected to the elastic ring 71, and the discharge pipe 76 seals and penetrates and is fixedly installed on the water pipe 63.

[0064] When the water pipe 63 intermittently inputs wastewater into the cylinder 41, the filter screen 72 can filter the solid particles and suspended matter in the wastewater, thereby effectively improving the efficiency and effect of the subsequent heating cylinder 42 heating the wastewater, and improving the distillation effect of the equipment on the wastewater (if the wastewater contains a large amount of solid impurities, such as suspended solids or dissolved solid particles, these solids will reduce the heat transfer efficiency of the wastewater). In addition, by intercepting solid impurities in the wastewater, the risk of impurities clogging the water pipe 63 can also be effectively reduced.

[0065] The heat conducting pipe 85 is arranged at the inner diameter of the water pipe 63, which is slightly smaller than the inner diameter of the water pipe 63. The purpose is that when the wastewater flows in the water pipe 63 and the water flows through the heat conducting pipe 85, the gap between the heat conducting pipe 85 and the inner wall of the water pipe 63 is small. Therefore, when the water flows through the heat conducting pipe 85, the flow rate of the water flow will increase. At this time, the impact force generated by the flow of the water will push the filter screen 72 to rotate backward, that is, the filter screen 72 rotates clockwise (such as Fig.14 The knocking ball 74 contacts the knocking plate 73, and the knocking force of the knocking ball 74 on the knocking plate 73 is transmitted to the filter 72, thereby achieving the effect of knocking and shaking off the filtered impurities on the filter 72, which can effectively improve the effect and efficiency of the filter 72 on continuous wastewater filtration.

[0066] Torsion springs (not shown) are fixedly installed between the two shafts and the elastic ring 71. Since the servo motor 64 cooperates with the conveying assembly 6 to supply water to the water pipe 63 intermittently, when the impact force generated by the water flow weakens, the filter screen 72 will rotate and reset under the action of the elastic force of the two torsion springs, so that the subsequent water flow intermittently drives the filter screen 72 to rotate, and the knocking ball 74 intermittently knocks the filter screen 72 to clean it.

[0067] At the same time, when the water flow impacts the filter screen 72 and the filter screen 72 rotates, the lower end of the filter screen 72 is limited by the blocking plate 75 (such as Fig.14 ), which can effectively ensure that the filter screen 72 can only rotate in the clockwise direction (as shown in FIG. Fig.14 The two torsion springs drive the filter 72 to rotate and reset under the action of their own elastic force. When the lower end of the filter 72 contacts the blocking plate 75, the blocking plate 75 can also produce a certain knocking effect on the filter 72, further improving the knocking and cleaning effect of the impurities intercepted on the filter 72.

[0068] The impurities that fall off the filter screen 72 due to the knocking will fall into the discharge pipe 76 under the action of gravity and the push of water flow, thereby achieving the effect of collecting impurities. When the equipment finishes distilling the wastewater, the valve on the discharge pipe 76 can be opened to collect the impurities gathered in the discharge pipe 76.

[0069] In addition, the purpose of setting the filter screen 72 to be sealed and rotatably installed in the elastic ring 71 is that when the water flow and the elastic force of the torsion spring drive the filter screen 72 to rotate inside the elastic ring 71, it can effectively prevent waste water from flowing out from the gap between the filter screen 72 and the elastic ring 71, thereby weakening the overall waste filtering effect of the filter screen 72. The purpose of setting the elastic ring 71 to be made of elastic material is to ensure that when the filter screen 72 is subjected to force and performs an arc rotation inside the elastic ring 71, the inner wall of the elastic ring 71 of the filter screen 72 will not hinder the movement of the filter screen 72.

[0070] like Figure 1 - Figure 7 As shown, the circulation component 5 includes an elastic telescopic rod 51 fixedly installed in the cylinder 41, and two elastic telescopic rods 51 are provided. A sealing plate 52 is fixedly installed between the two elastic telescopic rods 51, and the sealing plate 52 is sealingly slidably installed in the cylinder 41. An elastic sealing ring 53 is sealingly rotatably installed at the lower end of the heating cylinder 42, and one end of the elastic sealing ring 53 is fixedly connected to the sealing plate 52;

[0071] The cylinder 41 is provided with grooves evenly distributed in an annular shape, on which elastic baffle plates 2 57 are fixedly installed, on which reset springs 1 54 are fixedly installed, on which reset springs 1 54 are fixedly installed connecting blocks 55, and the connecting blocks 55 are all penetrated and fixedly installed on the corresponding elastic baffle plates 2 57, between which water-carrying plates 56 are fixedly installed, and the water-carrying plates 56 are sealingly and slidably installed between the cylinder 41 and the heating cylinder 42.

[0072] A reflux pipe 9 is fixedly connected between the cylinder body 41 and the liquid supply box 2, and the reflux pipe 9 passes through and is fixedly installed on the distillation kettle body 1. A sealing cover 43 is sealed and installed on the heating cylinder 42. A plate body 46 evenly distributed in a ring shape is fixedly installed on the heating cylinder 42. A liquid inlet pipe 47 is fixedly connected to the heating cylinder 42. Two liquid inlet pipes 47 are provided, and electric valves are installed on the two liquid inlet pipes 47.

[0073] The sealing cover 43 is provided with a plurality of air outlet holes (shown but not labeled in the figure, from Figure 3 As can be seen in FIG. 1 , when the wastewater in the heating cylinder 42 is heated, the steam generated can continue to move upward through the multiple air outlets (such as Figure 2 direction shown).

[0074] The heating cylinder 42 has an annular cavity in which a heater (which can be Figure 8 As can be seen in the figure, when the heating tube 42 is needed to heat the wastewater, the heater is started, and the operation of the heater will heat the wastewater inside the heating tube 42 by the wall of the heating tube 42.

[0075] An ultrasonic water level detector (not shown) is fixedly installed at the lower end of the sealing cover 43. The ultrasonic water level detector is an existing device. When the device starts running, the ultrasonic water level detector transmits ultrasonic pulses to the liquid surface, measures the ultrasonic round-trip time, and calculates the distance from the liquid surface to the sensor, thereby confirming the height of the water level.

[0076] When the water pipe 63 starts to inject water into the cylinder body 41, the water flow is intercepted by the water-carrying plate 56, and the water flow enters the heating cylinder 42 along the two liquid inlet pipes 47. When the ultrasonic water level detector at the lower end of the sealing cover 43 detects that the water level inside the heating cylinder 42 has reached a suitable height, it will send a signal to the two electric valves, so that the two electric valves are automatically closed, that is, the injection of water into the heating cylinder 42 is stopped, so that the heating cylinder 42 can heat and distill only a small part of the wastewater at a time. This can not only effectively reduce the energy consumption required for heating the wastewater (because a smaller liquid volume can reach the required evaporation temperature more quickly, thereby reducing the overall energy consumption required for wastewater heating), but also effectively improve the precise control of the wastewater heating temperature (a smaller volume of liquid can reach the target temperature more quickly), thereby improving the distillation effect of the wastewater.

[0077] At the same time, when the heating cylinder 42 has completed the heating and distillation of the internal wastewater, the ultrasonic water level detector and the electric valve can be used to open the electric valve again, so that the wastewater on the water-carrying plate 56 flows into the heating cylinder 42 again, and then the above operation is repeated to achieve the effect of continuous heating of the wastewater.

[0078] Moreover, the amount of waste water heated each time inside the heating cylinder 42 is relatively small, so as to ensure the impact force of the water flow from the water pipe 63 to the inside of the cylinder 41 on the multiple plates 46, so that the multiple plates 46 can cooperate to drive the heating cylinder 42 and the waste water inside the heating cylinder 42 to rotate intermittently (at the same time, when the amount of waste water heated by the heating cylinder 42 at a single time is relatively small, it can also effectively reduce the situation in which waste water splashes out from the air outlet on the sealing cover 43 during the rotation of the waste water inside the heating cylinder 42). At the same time, the amount of distilled waste water heated each time in the heating cylinder 42 can be adjusted up and down according to the impact force of the water flow output by the water pipe 63 (that is, the driving force of the servo motor 64), so as to effectively improve the flexibility of the use of the equipment.

[0079] like Figure 1 - Fig.14 As shown, the stirring mechanism 48 includes a reciprocating screw 481 rotatably mounted on the sealing plate 52, and the reciprocating screw 481 is sealed and installed on the heating tube 42, a placement groove is provided at the lower end of the heating tube 42, and a ring-shaped uniformly distributed tooth block 484 is fixedly installed on the placement groove, a rotating gear 485 is fixedly installed on the reciprocating screw 481, and the tooth block 484 is matched with the rotating gear 485, a slider 482 is installed on the reciprocating screw 481 through a ball nut, a fixed block 483 is threadedly mounted on the slider 482, and a ring-shaped uniformly distributed collecting box 486 is fixedly installed on the fixed block 483, a plurality of water filtering holes are provided on the collecting box 486, and a feed port 487 is provided on the collecting box 486.

[0080] The scraping component includes a square groove opened on the heating tube 42, on which an elastic baffle 410 is fixedly installed, on which a return spring 2 is fixedly installed, on which a support block 49 is fixedly installed at the lower end of the return spring 2, and the support block 49 is sealed and fixedly installed on the elastic baffle 410, and a scraper rod 411 is fixedly installed on the support block 49.

[0081] When the heating cylinder 42 is intermittently rotated by the impact of the water flow, the waste water inside it and the multiple tooth blocks 484 and the scraper 411 thereon will be driven to rotate together. At this time, the multiple water filtering holes on the multiple collecting boxes 486 can achieve the effect of stirring and mixing the rotating waste water, that is, effectively improve the uniformity of heating the internal waste water by the heating cylinder 42. During the rotation process, the multiple tooth blocks 484 can cooperate with the rotating gear 485, the reciprocating screw rod 481, and the slider 482 to make the multiple collecting boxes 486 intermittently move up and down (such as Fig. 9In the process of intermittent reciprocating up and down movement of the multiple collecting boxes 486 under force, the wastewater in the heating cylinder 42 can be further stirred and mixed, that is, the uniformity of heating of the entire wastewater inside the heating cylinder 42 can be further improved.

[0082] At the same time, when the heating cylinder 42 is intermittently rotated under force, one end of the multiple collecting boxes 486 that contacts the inner wall of the heating cylinder 42 can scrape off impurities such as crystals on the inner wall of the heating cylinder 42 (in the process of continuous heating of the wastewater by the heating cylinder 42, the solubility of some dissolved substances in the wastewater will be reduced, thereby prompting them to precipitate from the solution, forming crystals or precipitated impurities adhering to the inner wall of the heating cylinder 42, and when the impurities adhering to the cylinder wall gradually increase, the heating effect of the heating cylinder 42 on the wastewater inside it will gradually decrease), and when the multiple collecting boxes 486 intermittently move up and down, the crystals and other impurities on the inner wall of the entire heating cylinder 42 can be scraped off (the scraped impurities will fall on the inner bottom wall of the heating cylinder 42 under the action of gravity), which can effectively improve the effect and efficiency of the heating cylinder 42 continuously heating the wastewater inside it.

[0083] At the same time, when the heating cylinder 42 starts to heat the waste water inside it, the water pipe 63 continues to transport water to the inside of the cylinder 41, and the water will gather above the water carrying plate 56. When the weight of the water above the water carrying plate 56 is greater than the limit value that the multiple return springs 54 can withstand, the weight of the water will drive the water carrying plate 56 to move downward (such as Figure 6 When the lower end of the water-carrying plate 56 contacts the sealing plate 52, the water-carrying plate 56 presses the sealing plate 52, causing the sealing plate 52 to move downward together. When the sealing plate 52 moves downward, it drives the reciprocating screw rod 1 481 and the multiple collecting boxes 486 to move downward together. When the two elastic telescopic rods 2 51 are compressed to the limit, the lower ends of the multiple collecting boxes 486 just contact the inner bottom wall of the heating tube 42, that is, the water-carrying plate 56 and the sealing plate 52 stop moving.

[0084] When the plurality of collecting boxes 486 are in contact with the inner bottom wall of the heating cylinder 42, and the heating cylinder 42 is still subjected to force to intermittently drive the scraper rod 411 to rotate, the lower end of the collecting box 486 can scrape and clean the impurities such as crystals adhering to and collected on the inner bottom wall of the heating cylinder 42, thereby further cleaning the inner cylinder wall of the heating cylinder 42, further improving the continuous heating effect of the heating cylinder 42 on the internal wastewater, and from Figure 7 It can be seen that, affected by the setting orientation of the water pipe 63, the water flow generates an impact force to drive the heating cylinder 42 to rotate clockwise, so the impurities scraped by the multiple collection boxes 486 will continue to accumulate on the inclined surface of the collection box 486;

[0085] When the scraper rod 411 is rotated by force and contacts the collection box 486, the resistance of the collection box 486 to the scraper rod 411 and the driving force of the heating tube 42 on the scraper rod 411 will cause the scraper rod 411 to move upward along the inclined surface of the collection box 486. When the scraper rod 411 moves, it will push the impurities accumulated on the inclined surface of the collection box 486 to move upward together until the impurities are pushed to the feed inlet 487 and fall into the corresponding collection box 486 under the action of their own gravity, thereby achieving the effect of scraping and collecting impurities in the collection box 486, and when the scraper rod 411 moves to the upper end of the collection box 486 (such as Fig.10 When the collecting box 486 is still rotated under the force (in the direction shown), the low pressure exerted by the collecting box 486 on it disappears, and the scraper rod 411 moves downward and resets under the elastic force of the reset spring 2. The above operation is then repeated to remove the accumulated impurities on the inclined surfaces of the remaining collecting boxes 486 (and the multiple water filter holes on the collecting box 486 have small apertures. Therefore, when impurities enter the collecting box 486 and the collecting box 486 is still stirring and mixing the wastewater, it is difficult for the internal impurities to flow out from the multiple water filter holes on the collecting box 486 under the impact of the water flow).

[0086] The purpose of installing the elastic baffle 410 on the square groove is that when the scraper rod 411 is squeezed or stretched to move the reset spring 2 up and down, the elastic baffle 410 can be compressed and deformed, which can effectively prevent the waste water inside the heating tube 42 from entering the square groove and corroding the reset spring 2, thereby effectively improving the service life of the reset spring 2.

[0087] A door body is rotatably mounted on the distillation kettle body 1, and a sealing ring is fixedly mounted on the door body. The sealing ring can effectively reduce the water vapor generated by the heating cylinder 42 heating the waste water and the outflow from the gap between the door body and the distillation kettle body 1, thereby effectively ensuring the sealing effect of the distillation kettle body 1. At the same time, when the equipment finishes distilling the waste water, the sealing cover 43 is removed from the heating cylinder 42 by opening the door body, and then the multiple collecting boxes 486 can be taken out from the inside of the heating cylinder 42 by rotating the fixing block 483, so that the staff can pour out the impurities collected in the multiple collecting boxes 486 for cleaning. When the impurities in the multiple collecting boxes 486 are cleaned, the multiple collecting boxes 486 can be quickly fixed on the reciprocating screw rod 481 through the cooperation of the fixing block 483 and the slider 482. The operation is simple, which can effectively improve the convenience of using the equipment. Moreover, by taking out the multiple collecting boxes 486 from the heating cylinder 42 for cleaning, it is also convenient for the staff to further clean the inner wall of the heating cylinder 42, thereby further ensuring the subsequent heating effect of the heating cylinder 42 on the waste water.

[0088] When the water-carrying plate 56 moves downward under the gravity of the water body, the upper end of the water-carrying plate 56 moves below the upper end of the return pipe 9 (e.g. Figure 6 The waste water in the cylinder 41 will flow back to the liquid supply box 2 through the return pipe 9, and the diameter of the return pipe 9 is slightly larger than the diameter of the water delivery pipe 63. Therefore, when the water-carrying plate 56 presses the sealing plate 52 and stops moving for a period of time, the weight of the water on the water-carrying plate 56 will gradually decrease. When the weight of the water is less than the limit value that the multiple reset springs 54 can withstand, the water-carrying plate 56 and the sealing plate 52 can be moved up and reset (as shown in the direction ... Figure 6 When the weight of the water above the water-carrying plate 56 is again greater than the limit value that the multiple return springs 54 can withstand, the water-carrying plate 56 can be driven to move down again, and this cycle can be repeated to achieve the effect of multiple collecting boxes 486 intermittently scraping and collecting impurities adhered to and accumulated on the inner bottom wall of the heating tube 42.

[0089] At the same time, the purpose of installing the elastic sealing ring 53 between the sealing plate 52 and the heating tube 42 is to Figure 5 As the sealing plate 52 and the water-carrying plate 56 gradually move away from the lower end of the heating cylinder 42, the elastic sealing ring 53 can effectively prevent water from flowing into the lower end of the heating cylinder 42 and corroding the reciprocating screw 481.

[0090] When the water-carrying plate 56 is subjected to force to drive the multiple connecting blocks 55 thereon to move up and down, the multiple elastic baffles 57 can be compressed and tensilely deformed, which can effectively prevent the waste water inside the heating tube 42 from flowing into the multiple grooves and corroding the multiple return springs 54, thereby effectively improving the service life of the multiple return springs 54.

[0091] like Figure 1 - Figure 4 , Fig.11 , Fig.15 , Fig.16 As shown, the condensation component includes a condenser 81 fixedly installed on the heat conduction tube 85, a one-way liquid supply pipe 82 is fixedly connected between the condenser 81 and the cylinder 41, a one-way liquid return pipe 83 is fixedly connected between the condenser 81 and the cylinder 41, and the one-way liquid supply pipe 82 and the one-way liquid return pipe 83 are both sealed and penetrated and fixedly installed on the distillation kettle body 1.

[0092] After the wastewater in the heating cylinder 42 is continuously heated to steam, the steam will eventually flow into the heat conducting pipe 85. When the steam in the heat conducting pipe 85 flows through the pipe wall inside the liquid supply tank 2, the wastewater buffered inside the liquid supply tank 2 will perform preliminary cooling treatment on the steam. The heat absorbed by the wastewater when condensing the steam can achieve the effect of preheating itself, which can effectively improve the heating speed of the wastewater by the subsequent heating cylinder 42.

[0093] When the steam flows through the position of the condenser 81, the condensate inside the condenser 81 can further condense the steam inside the heat pipe 85. When the steam temperature is reduced to below the saturation temperature of the steam, the molecular movement speed of the steam is reduced and the distance between the molecules is reduced, the steam can be condensed into liquid. The liquid condensed inside the heat pipe 85 will eventually flow along the conduit 84 into the cache at the lower end of the distillation kettle body 1.

[0094] The distillation kettle body 1 is fixedly connected with a drain pipe (from Figure 2 As can be seen in the figure, a stop valve is installed on the discharge pipe. When the equipment finishes distilling the wastewater and the steam is condensed into liquid, the condensed liquid cached inside the distillation kettle body 1 can be collected by opening the stop valve.

[0095] At the same time, during the process of driving the sealing plate 52 to move up and down by the weight of the water inside the cylinder 41 (such as Figure 3 The one-way liquid supply pipe 82 and the one-way liquid return pipe 83 cooperate to achieve the effect of continuous flow of the condensate stored in the condenser pipe 81, that is, when the sealing plate 52 is forced to move downward (such as Figure 3 When the sealing plate 52 is forced to move upward, the suction force generated by the upward movement of the sealing plate 52 will draw part of the condensate in the condenser 81 back to the cylinder 41 through the one-way return pipe 83. In this way, the condensate stored in the condenser 81 can be continuously replaced, and the condensation rate of the steam by the condensate in the condenser 81 can be effectively improved (the flowing condensate will continuously take away the heat released during the condensation of the steam, so that the surface temperature of the heat transfer pipe 85 remains low, thereby enhancing the condensation rate of the steam).

[0096] The cylinder 41 is fixedly connected with a pipe body, and the pipe body seal passes through and is fixedly installed on the distillation kettle body 1, through which the cylinder 41 and the lower end of the sealing plate 52 (such as Figure 3 Condensate is injected into the condenser tube 81 in the direction shown in the figure, and the condensate inside the condenser tube 81 is replaced regularly to ensure the condensation effect of the condensate stored inside the condenser tube 81 on the steam inside the heat pipe 85.

[0097] The diameter of the guide tube 84 is much smaller than that of the heat pipe 85 , in order to increase the condensation time of the steam inside the heat pipe 85 and improve the condensation effect of the steam inside the heat pipe 85 .

[0098] like Fig.15 - Fig.17As shown, the cleaning mechanism 86 includes a reciprocating screw rod 861 rotatably installed in the heat pipe 85, a displacement frame 862 is installed on the reciprocating screw rod 861 through a ball nut, a fixing ring 863 is fixedly installed on the displacement frame 862, a limiting rod 864 is fixedly installed between the fixing ring 863 and the heat pipe 85, two limiting rods 864 are provided, an annular air bag 865 is fixedly installed on the fixing ring 863, a sponge 866 is fixedly installed on the annular air bag 865, and exhaust holes evenly distributed in a ring shape are opened on the annular air bag 865, a rotating shaft 867 is sealed and penetrated and rotatably installed on the heat pipe 85, a fan 868 is fixedly installed on the rotating shaft 867, a bevel gear 1 is fixedly installed on the rotating shaft 867, and a bevel gear 2 meshing with the bevel gear 1 is fixedly installed on the reciprocating screw rod 861.

[0099] The servo motor 64 cooperates with the conveying assembly 6 to intermittently draw gas into the suction pipe 61, which will flow along the air supply pipe 62 (such as Fig.13 The air moves upward (in the direction shown in the figure) and is finally discharged from the multiple circular holes opened on the air supply pipe 62 (from Fig.16 As can be seen in the figure, the air supply pipe 62 is provided with a plurality of circular holes. When the gas in the air supply pipe 62 flows through the fan 868, the gas drives the fan 868 to drive the rotating shaft 867 to rotate intermittently. During the rotation of the rotating shaft 867, the displacement frame 862 drives the fixing ring 863, the annular airbag 865, and the sponge 866 to intermittently reciprocate up and down through the cooperation of the bevel gear 1 and the bevel gear 2 and the reciprocating screw 2 861 (as shown in FIG. 1 ). Fig.16 In the direction shown), while the sponge 866 moves back and forth up and down, the water stains adhering to the heat pipe 85 can be wiped (when the steam encounters the cooled wall of the heat pipe 85 and is condensed into liquid, most of the liquid will move downward along the wall, while a small part of the liquid will remain on the wall to form water stains, and when the heat pipe 85 continues to condense the steam, the water stains on its internal wall will gradually increase, and when the water stains on the wall gradually increase, the heat conduction effect of the wall on the steam will gradually decrease, that is, the condensation speed of the steam will gradually decrease), thereby effectively ensuring the dryness of the inner wall of the heat pipe 85 and ensuring the condensation effect of the waste water and condensate inside the liquid supply box 2 on the internal steam through the heat pipe 85.

[0100] like Fig.12 , Fig.15 - Fig.17As shown, the pressure relief assembly 3 includes a pressure relief pipe 31 fixedly connected to the distillation kettle body 1, a square block is fixedly installed in the pressure relief pipe 31, two square blocks are provided, an elastic telescopic rod 33 is fixedly installed on the two square blocks, a sealing disk 34 is fixedly installed between the two elastic telescopic rods 33, and the sealing disk 34 is sealingly slidably installed in the pressure relief pipe 31, a delivery pipe 32 is fixedly connected between the pressure relief pipe 31 and the annular air bag 865, two delivery pipes 32 are provided, and the two delivery pipes 32 are sealed and penetrated and fixedly installed on the heat conduction pipe 85.

[0101] When the heating cylinder 42 continues to heat the wastewater inside, the pressure inside the distillation kettle body 1 gradually increases, and the gas (including steam) generated by the heating inside the distillation kettle body 1 pushes the sealing plate 34 (such as Fig.12 In the direction shown), the gas inside the distillation kettle body 1 enters into the two conveying pipes 32 along the pressure relief pipe 31, thereby achieving the effect of automatic pressure relief inside the distillation kettle body 1, and effectively improving the safety of the process of continuous heating of wastewater in the distillation kettle body 1 and the heating cylinder 42.

[0102] The multiple exhaust holes on the annular airbag 865 are relatively small, and the sum of the diameters of the multiple exhaust holes is smaller than the two delivery pipes 32, so that when the steam flows into the annular airbag 865 along the two delivery pipes 32 and is discharged along the multiple exhaust holes, the gas inside the annular airbag 865 will continue to increase;

[0103] When the gas in the annular airbag 865 increases, the gas can squeeze the inner wall of the annular airbag 865 to make it expand continuously. Since the fixed ring 863 limits the movement of the inner side of the annular airbag 865, when the gas squeezes the inner wall of the annular airbag 865, the annular airbag 865 will be forced to expand outward to squeeze the sponge 866 (such as Fig.17 In the direction shown, the position of the sponge 866 marked in the figure is the outside, and the position of the fixing ring 863 is the inside), so that the water absorbed by the sponge 866 can be automatically squeezed out, thereby improving the dryness of the sponge 866 during continuous use, and effectively ensuring that the sponge 866 can effectively absorb water stains on the inner wall of the heat pipe 85 when it is continuously moved up and down under force.

[0104] At the same time, when the internal pressure of the distillation kettle body 1 gradually decreases, the sealing disk 34 can be moved down and reset under the action of the elastic force of the two elastic telescopic rods 33 and the self-gravity of the sealing disk 34. That is, at this time, the two delivery pipes 32 stop supplying gas to the annular air bag 865. When the gas inside the annular air bag 865 is continuously discharged from multiple exhaust holes, the annular air bag 865 will gradually rebound and reset. Thereafter, the above operation is repeated to achieve the effect of squeezing the sponge 866 to absorb moisture again.

[0105] Instructions for use: When it is necessary to distill wastewater for thiazole production, start the servo motor 64. The operation of the servo motor 64 will cooperate with the conveying component 6 to filter the wastewater buffered in the liquid supply tank 2 through the filter screen 72, and then intermittently input it into the cylinder 41 and the heating cylinder 42. At this time, through the cooperation of the ultrasonic water level detector (existing equipment) and the two electric valves, the heating cylinder 42 can heat only a small part of the wastewater at a time. At the same time, in the process of conveying water to the inside of the cylinder 41, the impact force generated by the water flow will push the heating cylinder 42 to rotate intermittently. At this time, in cooperation with the stirring mechanism 48, the collecting box 486 can be moved up and down reciprocatingly and rotated to mix and stir the wastewater inside the heating cylinder 42. In addition, during the rotation of the heating cylinder 42, multiple collecting boxes 486 can be used to scrape off impurities such as crystals formed by heating on the inner wall of the heating cylinder 42.

[0106] When the wastewater in the cylinder 41 and above the water-carrying plate 56 gradually increases and the weight of the wastewater exceeds the limit value that the plurality of return springs 54 can bear, the water-carrying plate 56 will be forced to start moving downward (such as Figure 3 When the water-carrying plate 56 presses the sealing plate 52 to make the lower ends of the plurality of collecting boxes 486 contact the heating cylinder 42, the scraping component cooperates with the plurality of collecting boxes 486 to enable the collecting boxes 486 to scrape and collect impurities such as crystals adhered to and accumulated on the inner bottom wall of the heating cylinder 42.

[0107] When the steam formed by heating the wastewater in the heating tube 42 flows into the heat pipe 85, and the steam flows through the liquid supply tank 2, the wastewater buffered in the liquid supply tank 2 can be preliminarily condensed through the heat pipe 85, and the steam inside the heat pipe 85 can be condensed again through the condensing component, and the condensed liquid will flow into the distillation kettle body 1 through the conduit 84 for temporary storage.

[0108] At the same time, through the cooperation of the servo motor 64, the conveying component 6 and the cleaning mechanism 86, the sponge 866 can be driven to move up and down under force to wipe the water stains adhered to the inner wall of the heat pipe 85 (in the process of steam being continuously condensed into liquid inside the heat pipe 85, some liquid will adhere to the wall of the heat pipe 85). This can effectively ensure the dryness of the inner wall of the heat pipe 85 and improve the effect of continuous condensation of steam inside the heat pipe 85. When the air pressure inside the distillation kettle body 1 continues to increase, the pressure relief component 3 can achieve the effect of automatic pressure relief inside the distillation kettle body 1. Through the cooperation of the pressure relief component 3 and the annular airbag 865, the moisture adsorbed by the sponge 866 can be automatically squeezed out, thereby effectively ensuring the dryness of the sponge 866.

[0109] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
