Description

Technical Field

[0002] Low-temperature evaporation technology is widely used in chemical industry, pharmaceutical industry, environmental protection and other fields. For example, in the chemical industry, low-temperature evaporation technology can be used for concentration, purification, crystallization and other processes; in the pharmaceutical industry, it can be used for concentration and purification of drug solutions; in the environmental protection industry, it can be used for wastewater treatment, waste liquid recovery and other fields. Low-temperature evaporation equipment is equipment that realizes low-temperature evaporation technology. It is mainly composed of evaporator, condenser, vacuum system, heating system, control system and other parts. The evaporator is the core component of the equipment and is used to provide a place for liquid evaporation; the condenser is used to recover the evaporated steam to realize energy recycling; the vacuum system is used to reduce the pressure in the evaporator and reduce the boiling point of the liquid; the heating system is used to provide the heat required for evaporation; the control system is responsible for the operation and monitoring of the entire equipment.

[0003] The evaporator in the existing low-temperature evaporation equipment is mainly composed of an evaporating kettle and a heater. When in use, the waste liquid is first passed into the evaporating kettle through a pipeline, and then the heater heats the waste liquid. The vacuum system draws a vacuum to evaporate the liquid in the waste liquid, thereby achieving the purpose of low-temperature evaporation and drying. However, the evaporation speed is too slow, which is time-consuming and labor-intensive, and has high energy consumption. In addition, solids will be produced in the waste liquid during the evaporation process. Workers need to break the vacuum when enough solids have accumulated and release the solids and residual liquid together. Then, they need to use a sieve to filter out the solids from the residual liquid, and the filtrate is re-injected into the evaporating kettle for evaporation. The solids are placed in an oven for drying. The operation is time-consuming and labor-intensive, and the energy consumption is higher. Therefore, it is urgent to design a low-temperature evaporation and drying device for high-concentration hazardous waste liquid. Summary of the invention

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] ① Through the low-temperature evaporation mechanism, the high-concentration hazardous waste liquid low-temperature evaporation and drying device can reduce heat loss while realizing low-temperature evaporation technology, which helps to reduce energy consumption. At the same time, it can realize automatic supply of waste liquid, does not require manual operation, saves time and effort, and can rotate the stirring evaporator through the stirring mechanism to separate the area stained with waste liquid from the waste liquid. Through the stirring evaporator, the evaporation area of ​​the waste liquid is increased, which helps to increase the evaporation rate and reduce energy consumption. Through the efficiency-enhancing stirring element, the evaporation area of ​​the waste liquid is further increased, which helps to further increase the evaporation rate and further reduce energy consumption. Through the speed-increasing structure, the air flow rate at the gas-liquid interface can be increased, which can increase the evaporation rate again. The evaporation rate is faster, saving time and effort, less energy loss, high energy utilization rate, and low energy consumption, thereby improving the practicality of the high-concentration hazardous waste liquid low-temperature evaporation and drying device.

[0021] ② Through the flow distribution mechanism, the hot fluid can flow inside the stirring evaporator and the efficiency-enhancing stirring member to maintain the temperature of the stirring evaporator and the efficiency-enhancing stirring member, which helps to increase the heat dissipation speed. At the same time, the flow distribution mechanism can inject the circulated hot fluid into the interlayer cavity of the low-temperature evaporation mechanism and the filter residue mechanism to utilize the waste heat, which has better energy utilization and helps to reduce energy consumption. The solids generated in the waste liquid can be pushed out through the filter residue mechanism without breaking the vacuum environment, which helps to further reduce energy consumption. The pushed out solids can be collected through the toggle mechanism, and the solids collected by the toggle mechanism are heated by the low-temperature evaporation mechanism. The liquid on the surface of the solid is evaporated under negative pressure to achieve drying, which helps to reduce energy consumption again. At the same time, the toggle mechanism can also stir the solid and turn the solid over, which helps to increase the evaporation rate. Through the cleaner, workers can transfer the dried solid out, which saves time and effort. The stripping mechanism can scrape off the solids adhering to the stirring evaporator and the efficiency-enhancing stirring piece to ensure that the stirring evaporator and the efficiency-enhancing stirring piece are not covered by the solid, so as to maintain the efficiency of the stirring evaporator and the efficiency-enhancing stirring piece to transfer heat to the waste liquid, which helps to further increase the evaporation rate and improve the low-temperature evaporation and drying device for high-concentration hazardous waste liquid.

[0047] Working principle:

[0048] First, the hot fluid enters the distribution inlet pipe 56 through the hot fluid injection pipe 112, and then the hot fluid enters the right distribution circular box 52 through the distribution inlet pipe 56, and then the hot fluid passes through the right distribution flow hole 55 to enter the heat storage outer clamp chamber 33, and then the hot fluid passes through the flow short pipe 46, the adaptation groove 43, the delivery channel 44, the semicircular channel 45, another delivery channel 44, another adaptation groove 43, and the flow long pipe 47 to enter the heat storage inner clamp chamber 35, and then the temperature of the efficiencies stirring disc 41 and the stirring evaporation outer cylinder 31 rises, and then the hot fluid inside the heat storage inner clamp chamber 35 passes through the left distribution flow hole 53 to enter the left distribution circular box 51, and then the hot fluid passes through the distribution outlet pipe 54 to enter the interlayer cavity at the left end of the insulation clamp chamber box 103, and then the hot fluid passes through the tapered The interlayer cavity on the interlayer tube 104, the interlayer cavity on the filter residue interlayer vertical tube 71, the interlayer cavity on the filter residue interlayer horizontal tube 72, and the interlayer cavity on the filter residue interlayer curved tube 75 enter the interlayer cavity on the right end of the insulation interlayer box 103. In this process, the hot fluid heats the insulation interlayer box 103 and the tapered interlayer tube 104, and then the hot fluid flows back to the heating equipment through the heat flow discharge pipe 113. Then the insulation interlayer box 103, the tapered interlayer tube 104, the stirring evaporation outer cylinder 31, and the efficiency-enhancing stirring disc 41 heat the waste liquid to increase the temperature of the waste liquid, and then the waste liquid evaporates. Then the vacuum pump 109 works under the control of the intelligent controller 110, and then the air and steam in the cavity where the efficiency-enhancing stirring disc 41 is located enter the speed-increasing circulation through the right circulation through hole 67. The ring cavity 62 moves the air and steam in the chamber 801 into the speed-increasing circulation cavity 62 through the exhaust hole 814, and then the intelligent controller 110 controls the driving duct fan 66 to work, and then the air in the speed-increasing circulation cavity 62, the left circulation through hole 65, the arc groove 64, the cavity where the efficiency-enhancing stirring flying disc 41 is located, and the right circulation through hole 67 circulates counterclockwise under the drive of the driving duct fan 66, and then the air flow rate at the gas-liquid interface increases, so that the evaporation rate of the waste liquid is increased, and then the air and steam inside the speed-increasing circulation cavity 62 enter the condenser 107 through the suction pipe 108, and then the condenser 107 cools the steam to liquefy the steam into liquid, and at the same time the air is discharged through the vacuum pump 109, and people can release the liquid inside the condenser 107, and then The rear stirring motor 21 works under the control of the intelligent controller 110, and then the stirring motor 21 drives the stirring short shaft 25 to rotate through the stirring pulley 22, the stirring belt 23, and the transmission pulley 24, and then the stirring short shaft 25 drives the stirring evaporation middle cylinder 32 to rotate, and then the stirring evaporation middle cylinder 32 drives the stirring evaporation outer cylinder 31 to rotate, and then the stirring evaporation outer cylinder 31 drives the efficiency-enhancing stirring flying disc 41 to rotate, and then the stirring evaporation outer cylinder 31 and the efficiency-enhancing stirring flying disc 41 will stir the waste liquid when they rotate out of the waste liquid, thereby increasing the evaporation area of ​​the waste liquid and accelerating the evaporation speed. At the same time, a thin layer of waste liquid will adhere to the area of ​​the stirring evaporation outer cylinder 31 and the efficiency-enhancing stirring flying disc 41 that has just rotated out of the waste liquid, thereby increasing the evaporation area of ​​the waste liquid and accelerating the evaporation speed.Afterwards, the substances in the waste liquid precipitate to form solids and adhere to the surfaces of the stirring evaporation outer cylinder 31 and the efficiency-enhancing stirring disc 41. Then, the stripping flap 12 applies pressure to the stripping comb teeth 14 under the action of the elastic tension of the stripping tension spring 13, so that the ends of the stripping comb teeth 14 are pressed on the surface of the stirring evaporation outer cylinder 31. Then, the stripping comb teeth 14 slide on the surfaces of the efficiency-enhancing stirring disc 41 and the stirring evaporation outer cylinder 31 to scrape off the solids attached to the surfaces of the stirring evaporation outer cylinder 31 and the efficiency-enhancing stirring disc 41. The scraped solids fall into the waste liquid and sink. The solids pass through the tapered sandwich tube 104 and the filter residue sandwich vertical tube 71 and enter the filter residue sandwich horizontal tube 72. Then, as the evaporation work proceeds, the liquid level of the waste liquid above the tapered sandwich tube 104 will gradually drop, and then the liquid level meter 11 5 The liquid level is detected in real time and the information is sent to the intelligent controller 110. When the liquid level is lower than the minimum value preset in the intelligent controller 110, the intelligent controller 110 controls the solenoid valve to open, so that the waste liquid enters the space where the efficiency-enhancing stirring disc 41 is located through the waste liquid pipe 111. Then the liquid level gradually increases. When the liquid level reaches the maximum value preset in the intelligent controller 110, the intelligent controller 110 controls the solenoid valve to close, so as to maintain the liquid level, so that the stirring evaporation outer cylinder 31 and the lower part of the efficiency-enhancing stirring disc 41 remain immersed in the waste liquid. Then, as the evaporation work proceeds, the solids inside the tapered sandwich tube 104, the filter residue sandwich vertical tube 71, and the filter residue sandwich horizontal tube 72 gradually increase, and then the intelligent controller 110 opens the filter residue. Motor 73, then the residue motor 73 drives the residue auger 74 to rotate, and then the residue auger 74 pushes the solid to move upward inside the residue sandwich elbow 75 and the single-layer inclined tube 76, and the solid-liquid separation is achieved when the solid moves to a position above the liquid surface, and then the solid is discharged from the top of the single-layer inclined tube 76, and then the solid falls into the inside of the toggle cavity 816, and then the heat-insulating sandwich cavity box 103 heats the solid to evaporate the liquid on the surface of the solid, and then the stirring evaporation outer cylinder 31 is driven by the toggle main shaft 812, the toggle main wheel 811, the toggle wide band 810, the toggle slave wheel 809, the toggle short shaft 808, the meshing action between the tapered bevel gear 94 and the tapered concave tooth groove 93, the cleaning of the rough head 91, the toggle horizontal shaft 805, the toggle radial rod 806 with the toggle The horizontal bar 807 rotates, and then the horizontal bar 807 is moved to stir the solid, so that the liquid on the surface of the solid evaporates quickly until the solid is dried. After a lot of solids accumulate in the moving cavity 816, the vacuum pump 109 is controlled by the intelligent controller 110 to stop vacuuming, and then the locking bolt 97 is rotated, and then the locking bolt 97 is separated from the cavity partition plate 802, and then the sealing baffle 96 is pulled to move to the right, and then the sealing baffle 96 passes through the sealing sandwich door 95, the moving horizontal shaft 805, and the cleaning rough head 91 to move the cleaning vertical plate 92 to the right, and then the tapered bevel gear 94 is pulled out from the tapered concave tooth groove 93, and then the cleaning vertical plate 92 pushes the solid inside the moving cavity 816 to move to the right, and then the solid is discharged from the discharge port, and then the sealing baffle 96 is pushed to the left.Then the tapered bevel gear 94 is inserted into the tapered concave tooth groove 93, the vertical plate 92 is cleaned and reset to the left, and then the locking bolt 97 is reversed, and then the locking bolt 97 fixes the sealing baffle 96 and the compartment vertical plate 802 together to achieve sealing, and then the vacuum pump 109 is controlled by the intelligent controller 110 to evacuate the vacuum, and then the evaporation work is continued as above.
