Description

Technical Field

[0001] The invention relates to the field of mesotrione preparation, in particular to a sewage discharge device used for mesotrione synthesis. Background Art

[0002] The mesotrione production process generates a large amount of organic wastewater, which is divided into acidic and alkaline wastewater. The acidic wastewater contains high concentrations of sulfuric acid, while the alkaline wastewater contains large amounts of triethylamine. Direct discharge into rivers can have a serious impact on fish and shrimp. Traditional wastewater treatment methods first neutralize the acidic and alkaline wastewaters, then filter press to remove inorganic salts, and then perform multi-effect evaporation to reduce the organic matter content in the wastewater.

[0003] However, this method will first consume a large amount of heat, and the waste gas generated during the production of mesotrione has heat. In traditional equipment, the heat of these waste gases will be naturally dissipated during the subsequent treatment process and will not be utilized. Moreover, the heating and drying sludge in traditional equipment not only consumes a lot of heat, but also has a low sludge drying efficiency. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a sewage discharge device for mesotrione synthesis, which solves the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a sewage discharge device for mesotrione synthesis, comprising a treatment box, wherein insulation boxes are fixedly installed at the upper and lower ends of the treatment box, and further comprising a plurality of matrix-distributed heating rods located within the treatment box, wherein the upper and lower ends of the heating rods are respectively connected to the upper and lower insulation boxes by heat pipes, wherein an air separation chamber is installed within the insulation box, wherein two air pipes are installed on the air separation chamber, wherein the air pipes transport external high-temperature exhaust gas into the air separation chamber and circulate through the heat pipes and the heating rods to heat the heating rods;

[0006] It also includes a decontamination assembly, which is arranged in the processing box. The heating rod and the heat pipe are both passed through the decontamination assembly. Two hoists are fixedly installed in the insulation box above. The hoists are connected to the decontamination assembly with cables and are used to move the decontamination assembly up and down in the processing box.

[0007] Wastewater discharge components are installed on both sides of the upper end of the treatment box. When the decontamination component moves to the uppermost end, the wastewater discharge component opens, and two streams of wastewater enter the treatment box and mix above the decontamination component.

[0008] It also includes a plurality of vertical pipes, which pass through the decontamination assembly. When the decontamination assembly moves to the bottom, the wastewater above the decontamination assembly enters the decontamination assembly through the vertical pipes;

[0009] A sewage outlet is installed on one side of the bottom of the processing box, and a plurality of waste gas inlet pipes are installed corresponding to the sewage outlet on the other side.

[0010] Preferably, the decontamination component includes a water tank and a drying pipe. The water tank is located in the treatment tank. The drying pipes are provided with a plurality of drying pipes distributed in a matrix, corresponding to the number and position of the heating rods. The upper end of the drying pipe is fixed to the bottom surface of the water tank and is connected to the interior of the water tank. The heating rod passes through the drying pipe and is slidably connected to it. The end of the heating rod inside the drying pipe does not contact the inner wall of the drying pipe. The heating rod contacts the inner wall of the end of the drying pipe away from the water tank and seals the bottom end of the drying pipe. The heat-conducting pipes at the top all pass through the water tank and are slidably sealed therewith. The water tank is fixed to the end of the cable away from the elevator. The riser passes through the water tank. When the water tank moves to the lower end, the bottom end of the heating rod moves relatively to above the bottom end of the drying pipe. At this time, the bottom end of the drying pipe is in an open state, and the wastewater in the treatment tank can enter the water tank through the riser. When the water tank moves to the top, the upper end of the heating rod moves from the inside of the upper end of the drying pipe to the lower end of the drying pipe, but the drying pipe is always sealed.

[0011] Preferably, the drying pipe is a vertical through-type structure, the end of the drying pipe connected to the water tank is a trumpet-shaped opening structure, and the end away from the water tank is a conical contraction structure.

[0012] Preferably, two groups of through holes distributed vertically are provided on the side of the standpipe, and the through holes are connected to the interior of the standpipe. Each group of through holes is provided with a plurality of through holes, which are distributed in a surrounding array on the outside of the standpipe. The inside of the standpipe is a cavity structure between the two groups of through holes. When the water tank moves to the lowest end, the standpipe moves upward relative to the water tank. At this time, the upper group of through holes on the standpipe are outside the water tank, and the lower group of through holes on the standpipe are inside the water tank.

[0013] Preferably, a sealing ring is further included, which is sleeved on the side of the water tank and contacts the inner wall of the treatment tank to seal the water tank and the treatment tank.

[0014] Preferably, the wastewater discharge assembly includes a water inlet pipe, a cone plug, a plug ring, a rocker arm and a torsion spring. The water inlet pipe is installed at the external side of the treatment box and is connected to the inside of the treatment box. The plug ring is fixedly installed in the treatment box and corresponds to the water inlet pipe. One end of the rocker arm is connected to the end of the cone plug away from the water inlet pipe. The torsion spring is between the cone plug and the plug ring and connects the two. When the torsion spring is not under force, the cone plug is screwed into the plug ring and seals the plug ring. When the water tank moves up to lift the rocker arm, the cone plug can be screwed out of the plug ring. At this time, the water inlet pipe is connected to the water tank, and the torsion spring is twisted under force.

[0015] Preferably, it also includes a roller, which is installed on the end of the rocker arm away from the cone plug and is rotatably connected thereto, and the roller can contact the water tank.

[0016] Preferably, the cone plug is a cone-shaped structure, with a plurality of spiral tracks provided on the cone-shaped side surface, and the inner ring of the plug ring is provided with spiral protrusions that cooperate with the spiral tracks.

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

[0018] 1. The sewage discharge device for mesotrione synthesis is provided with a decontamination component, a heating rod, a riser and a gas separation chamber. The high-temperature waste gas generated in the early stage of the mesotrione chemical reaction can circulate through the two gas separation chambers to heat the heating rod. Then, when the wastewater enters the water tank, it can enter the drying pipe. The wastewater in the drying pipe contacts the heating rod, and the organic pollutants therein can agglomerate and adhere to the heating rod to form sludge. Then, the elevator works periodically, first lifting the water tank to move the heating rod downward relative to the drying pipe. At this time, the sludge outside the heating rod will be discharged by the drying pipe. The bottom is scraped off and accumulated at the bottom of the drying pipe, and then the water tank is lowered, and the heating rod is moved up relative to the drying pipe until its bottom enters the drying pipe. The bottom of the drying pipe loses its seal, and the wastewater at the upper end inside it will push out the sludge deposited at the bottom. At this time, the wastewater above the water tank will enter the water tank through the riser for replenishment, and then continue to be heated by the heating rod to discharge the sludge. Therefore, when synthesizing mesotrione, the organic wastewater can use the residual heat of the waste gas to dry the sludge, and the matrix periodic drying is adopted, which has higher precipitation efficiency and saves more heat.

[0019] 2. The sewage discharge device used for mesotrione synthesis has a large amount of wastewater inside the drying pipe. When the sludge is pushed out of the drying pipe, part of the wastewater inside will flow out, and the wastewater above will be immediately replenished. Therefore, the wastewater inside the drying pipe will be heated by the heating rod multiple times until the sludge content in the water decreases as it goes down. When the number of drying pipes is sufficient, the effect of large-flow wastewater treatment can be achieved.

[0020] 3. The sewage discharge device for mesotrione synthesis is provided with a wastewater discharge assembly. When the water tank moves upward, the volume of the cavity above the treatment tank will become smaller and smaller until it becomes a thinner cavity. At this time, when the water tank lifts the rocker arm, the cone plug can be rotated out of the plug ring, and the water inlet pipe is connected to the water tank, so that external wastewater can enter the treatment tank. The left and right wastewater discharge assemblies can respectively connect acidic wastewater and alkaline wastewater. When mixing, the pH value can be balanced and inorganic salts can be precipitated. The compressed chamber can quickly mix the two without stirring, and the combination efficiency is higher. Each time the water tank moves downward, the mixed wastewater will pass through the riser into the water tank, and then move upward to be replenished with new wastewater. Separate treatment consumes less energy, and the reaction is sufficient, which is suitable for adding drugs.

[0021] 4. The sewage discharge device for mesotrione synthesis is provided with a sewage discharge port and an exhaust gas inlet pipe. The exhaust gas inlet pipe can be connected to the gas pipeline. The excess exhaust gas is used to further dry and blow out the sludge at the bottom of the treatment box, thereby further reducing the moisture content in the sludge during collection.

[0036] like Figure 1-9 As shown, a sewage discharge device for mesotrione synthesis includes a treatment box 1, with insulation boxes 2 fixedly installed at the upper and lower ends of the treatment box 1, and a plurality of heating rods 3 distributed in a matrix. The heating rods 3 are located in the treatment box 1, and the upper and lower ends of the heating rods 3 are respectively connected to the upper and lower insulation boxes 2 by heat pipes 4. An air distribution chamber 5 is installed in the insulation box 2, and two air pipes 10 are installed on the air distribution chamber 5. The air pipes 10 transport the external high-temperature exhaust gas into the air distribution chamber 5 and circulate it through the heat pipes 4 and the heating rods 3 to heat the heating rods 3.

[0037] The cleaning assembly 6 is also included, which is arranged in the processing box 1. The heating rod 3 and the heat pipe 4 both pass through the cleaning assembly 6. Two hoists 7 are fixedly installed in the upper insulation box 2. The hoists 7 are connected to the cleaning assembly 6 by cables 8 and are used to move the cleaning assembly 6 up and down in the processing box 1.

[0038] Wastewater discharge components 9 are installed on both side walls of the upper end of the treatment box 1. When the decontamination component 6 moves to the uppermost end, the wastewater discharge component 9 opens, and two streams of wastewater enter the treatment box 1 and mix above the decontamination component 6;

[0039] It also includes a plurality of vertical pipes 11, which pass through the decontamination assembly 6. When the decontamination assembly 6 moves to the bottom, the wastewater above the decontamination assembly 6 enters the decontamination assembly 6 through the vertical pipes 11.

[0040] A sewage outlet 12 is installed on one side of the bottom of the processing box 1, and a plurality of waste gas inlet pipes 13 are installed on the other side corresponding to the sewage outlet 12.

[0041] The insulation box 2 is used to prevent the heat inside the gas distribution chamber 5 from dissipating. The gas pipe 10 is used to connect the early gas collection equipment. When the temperature of the exhaust gas absorbed by the early machinery and equipment is not enough or the exhaust gas is small, it can also be connected to steam or the waste heat gas from the remaining reaction combustion chambers. A variety of heating methods can also be used according to the actual conditions of the factory. The elevator 7 includes a motor and a winch. When the decontamination component 6 is large enough, the specifications of the motor can be adjusted according to the situation. The elevator 7 is used for periodic control of lifting the decontamination component 6. The sewage outlet 12 is a square trough type. The sludge can be gradually discharged from the sewage outlet 12, and the exhaust gas inlet pipe 13 can also further dry the sludge, and the airflow can also be used to push the sludge out.

[0042] The decontamination component 6 includes a water tank 601 and a drying tube 602. The water tank 601 is located in the treatment box 1. The drying tubes 602 are provided with a plurality of matrix distributions, corresponding to the number and position of the heating rods 3. The upper end of the drying tube 602 is fixed to the bottom surface of the water tank 601 and is connected to the interior of the water tank 601. The heating rod 3 passes through the drying tube 602 and is slidably connected thereto. One end of the heating rod 3 inside the drying tube 602 does not contact the inner wall of the drying tube 602. The heating rod 3 contacts the inner wall of the drying tube 602 at one end away from the water tank 601 and seals the bottom end of the drying tube 602, which is located above the heat conduction tube. The tubes 4 all pass through the water tank 601 and are slidingly sealed with it. The water tank 601 is fixed to the end of the cable 8 away from the elevator 7. The vertical pipe 11 passes through the water tank 601. When the water tank 601 moves to the lowermost end, the bottom end of the heating rod 3 moves relatively to the top of the bottom end of the drying pipe 602. At this time, the bottom end of the drying pipe 602 is in an open state, and the wastewater in the treatment box 1 can enter the water tank 601 through the vertical pipe 11. When the water tank 601 moves to the top, the upper end of the heating rod 3 moves from the inside of the upper end of the drying pipe 602 to the lower end of the drying pipe 602, but the drying pipe 602 is always sealed.

[0043] The bottom end of the drying tube 602 matches the diameter of the heating rod 3. The drying tube 602 moves to scrape off the sludge on the outside of the heating rod 3, and when the bottom end of the drying tube 602 is inserted into the heating rod 3, the waste water therein will not drip.

[0044] The drying pipe 602 is a vertical through-type structure. The end of the drying pipe 602 connected to the water tank 601 is a trumpet-shaped opening structure, and the end away from the water tank 601 is a conical contraction structure.

[0045] The conical contraction structure makes it easier to collect the sludge outside the heating rod 3, and the trumpet-shaped opening structure allows wastewater to enter the interior thereof.

[0046] Two groups of through holes 14 are provided on the side of the standpipe 11, distributed vertically. The through holes 14 are connected to the interior of the standpipe 11. Each group of through holes 14 is provided with multiple through holes, which are distributed in a surrounding array on the outside of the standpipe 11. The inside of the standpipe 11 is a cavity structure between the two groups of through holes 14. When the water tank 601 moves to the lowest end, the standpipe 11 moves upward relative to the water tank 601. At this time, the upper group of through holes 14 on the standpipe 11 is outside the water tank 601, and the lower group of through holes 14 on the standpipe 11 is inside the water tank 601.

[0047] The through hole 14 facilitates the wastewater above the water tank 601 to enter the water tank 601, and providing multiple through holes 14 can improve the entry efficiency.

[0048] It also includes a sealing ring 603, which is sleeved on the side of the water tank 601 and contacts the inner wall of the treatment box 1, and is used to seal the water tank 601 and the treatment box 1.

[0049] Prevent waste water above the water tank 601 from flowing to the lower part.

[0050] The wastewater discharge assembly 9 includes an inlet pipe 901, a conical plug 902, a plug ring 903, a rocker arm 904 and a torsion spring 905. The inlet pipe 901 is installed on the external side of the treatment box 1 and is connected to the inside of the treatment box 1. The plug ring 903 is fixedly installed in the treatment box 1 and corresponds to the inlet pipe 901. One end of the rocker arm 904 is connected to the end of the conical plug 902 away from the water inlet pipe 901. The torsion spring 905 is between the conical plug 902 and the plug ring 903 and connects the two. When the torsion spring 905 is not under force, the conical plug 902 is screwed into the plug ring 903 and seals the plug ring 903. When the water tank 601 moves up and lifts the rocker arm 904, the conical plug 902 can be screwed out of the plug ring 903. At this time, the water inlet pipe 901 is connected to the water tank 601, and the torsion spring 905 is twisted under force.

[0051] The plug ring 903 and the cone plug 902 can both be made of hard plastic or rubber metal, and have a certain sealing property after being screwed in together.

[0052] It also includes a roller 906, which is installed on the end of the rocker arm 904 away from the cone plug 902 and is rotatably connected thereto, and the roller 906 can contact the water tank 601.

[0053] Roller 906 is used to reduce friction and increase the service life of the equipment.

[0054] The cone plug 902 is a cone-shaped structure with a plurality of spiral paths provided on its cone-shaped side surface. The inner ring of the plug ring 903 is provided with spiral protrusions that match the spiral paths.

[0055] After the two are unscrewed, wastewater can enter the treatment box 1 through the spiral channel or the gap between the spiral protrusions.

[0056] During use, the high-temperature exhaust gas generated by the early mesotrione chemical reaction can circulate through the two gas separation chambers 5 and is also connected to the exhaust gas inlet pipe 13. The gas separation chamber 5 can transfer heat to the heating rod 3 through the heat conduction pipe 4 to heat the heating rod 3. Then, when the wastewater enters the water tank 601, it can enter the drying pipe 602. The wastewater in the drying pipe 602 contacts the heating rod 3, and the organic pollutants and precipitated inorganic salts therein can agglomerate and adhere to the heating rod 3 to form sludge. Then the elevator 7 works periodically, first lifting the water tank 601 to move the heating rod 3 downward relative to the drying pipe 602. At this time, the outside of the heating rod 3 The sludge will be scraped off from the bottom of the drying pipe 602 and accumulated at the bottom of the drying pipe 602. When the water tank 601 moves up, the volume of the upper cavity in the treatment box 1 will become smaller and smaller until it becomes a thinner cavity. At this time, when the water tank 601 lifts the rocker arm 904, the cone plug 902 can be screwed out from the plug ring 903, and the water inlet pipe 901 is connected to the water tank 601. External wastewater can enter the treatment box 1. The left and right wastewater discharge components 9 can be connected to acidic wastewater and alkaline wastewater respectively. During mixing, the pH value can be balanced and inorganic salts can be precipitated. The compressed chamber can make the two mix quickly without stirring. Then lower the water tank 601, and move the heating rod 3 upward relative to the drying pipe 602 until its bottom end enters the drying pipe 602. The bottom of the drying pipe 602 loses its seal, and the wastewater at the upper end inside it will push out the sludge deposited at its bottom. At this time, the wastewater above the water tank 601 will enter the water tank 601 through the riser 11 for replenishment. Since when the drying pipe 602 pushes out the sludge, part of the wastewater inside it will flow out, and the wastewater above will be replenished immediately, so the wastewater inside the drying pipe 602 will be heated by the heating rod 3 multiple times until the sludge content in the water becomes less as it goes down, and then the sludge will continue to be heated by the heating rod 3 to be discharged. The waste gas inlet pipe 13 can be connected to the gas pipe 10, and the excess waste gas can be used to continue to dry and blow out the sludge at the bottom of the treatment box 1, further reducing the moisture content in the sludge while collecting it.
