Description

Technical Field

[0001] The invention relates to the technical field of distillation equipment, in particular to a waste liquid distillation capture and recovery device. Background Art

[0002] Waste liquid distillation treatment utilizes the different boiling points of various substances in the waste liquid to heat the waste liquid so that the substances in the waste liquid reach their boiling point and vaporize and volatilize, and then collect them by condensation to achieve the purpose of separation. This treatment method can recycle recyclable substances in the waste liquid and reduce resource waste. It can also separate organic matter and other substances in the waste liquid, thereby facilitating subsequent purification work. Waste liquid distillation is generally suitable for the treatment of waste liquids containing high-value organic solvents or other volatile components, such as waste liquids generated by chemical, pharmaceutical, printing, electronics, coatings and other industries.

[0003] When using existing waste liquid distillation equipment, the waste liquid stored in the distillation tower is generally heated directly as a whole. However, since the vaporization and volatilization of substances in the waste liquid generally only occur on the liquid surface, the volatilization effect achieved in the middle of the waste liquid is not obvious. Therefore, the speed of waste liquid distillation is greatly limited, affecting work efficiency. At the same time, since the middle of the waste liquid cannot volatilize, the operation method of heating and keeping the waste liquid warm as a whole will cause a large loss of energy.

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0045] like Figures 1 to 3 As shown, a waste liquid distillation capture and recovery device of the present invention comprises a distillation structure 100 for heating distillation waste liquid, a condensation structure 300 for condensing distilled gas, a flow guide structure 200 for transferring the distilled gas to the condensation structure 300, and a drainage structure 400 for discharging the condensed liquid. The distillation structure 100, the flow guide structure 200 and the condensation structure 300 are sequentially connected from bottom to top, and the drainage structure 400 is installed on the condensation structure 300.

[0046] The distillation structure 100 includes a first storage chamber 101 on the outside and a second storage chamber 102 located inside the first storage chamber 101. A channel is formed between the first storage chamber 101 and the second storage chamber 102, and the channel is used for the flow of waste liquid. An opening formed between the top of the first storage chamber 101 and the top of the second storage chamber 102 is set as a liquid dispersion port 103. The liquid dispersion port 103 is annular in shape and horizontally faces the vertical axis direction of the first storage chamber 101. A heating plate 104 is arranged on the inside of the second storage chamber 102, and the shape of the heating plate 104 is conical.

[0047] A plurality of liquid guide holes 105 are provided at the bottom of the second storage chamber 102, and waste liquid in the second storage chamber 102 flows into a channel through the liquid guide holes 105. A power structure is provided in the channel to push the waste liquid in the channel to flow upward along the channel.

[0048] In detail, heating structures such as electric heating wires and electric heating rods can be arranged on the heating plate 104 to realize the heating function. The distillation structure 100 is provided with a pipeline for supplying waste liquid therein, and the pipeline is not shown in the accompanying drawings. A discharge port and a cover plate are arranged at the bottom of the first storage chamber 101. The liquid remaining in the first storage chamber 101 after the distillation process can be discharged through the discharge port.

[0049] The distillation structure 100 can heat and distill the waste liquid therein. Some substances in the waste liquid reach boiling point and volatilize by distillation. The distilled gas enters the condensation structure 300 through the guide structure 200 for condensation, and the condensed liquid is discharged through the drainage structure 400, thereby realizing the distillation recovery of the waste liquid.

[0050] The first storage chamber 101 and the second storage chamber 102 are both in the shape of a buckled bowl, with their openings facing upwards. The second storage chamber 102 is located on the inner side of the first storage chamber 101. The interior of the second storage chamber 102 is used to store waste liquid. The channel formed between the first storage chamber 101 and the second storage chamber 102 is used for the flow of waste liquid. The liquid dispersion port 103 is in the shape of a ring, and its direction is toward the vertical axis of the first storage chamber 101. When the waste liquid flows from the channel into the liquid dispersion port 103, the waste liquid flows to the heating plate 104 through the liquid dispersion port 103. At this time, the waste liquid covers the inner wall of the heating plate 104, and the thickness of the waste liquid is small. The heating plate 104 heats the waste liquid thereon. Since the thickness of the waste liquid is relatively small, the waste liquid is heated quickly. Since the waste liquid covers the inner wall of the heating plate 104 and flows, the coverage area of ​​the waste liquid can be increased. These two aspects can accelerate the distillation speed of the waste liquid, thereby accelerating the waste liquid treatment efficiency. The waste liquid that is not distilled in time flows back into the second storage chamber 102, and the waste liquid in the second storage chamber 102 flows into the channel through the liquid guide hole 105. The power structure can provide thrust for the waste liquid in the channel, so that the waste liquid flows upward along the channel, thus realizing the circulating distillation of the waste liquid. At the same time, since only the waste liquid on the heating plate 104 needs to be heated, and the waste liquid in other positions does not need to be kept at a high temperature, the energy consumption can be greatly reduced.

[0051] By making the heating plate 104 conical and directly heating the waste liquid on the heating plate 104, the coverage area of ​​the waste liquid is increased and the thickness is reduced, which significantly speeds up the heating speed of the waste liquid, thereby accelerating the distillation process. The combination of rapid evaporation of the waste liquid on the heating plate 104 and the circulation flow design effectively improves the distillation efficiency and shortens the processing time; only the waste liquid on the heating plate 104 is centrally heated, rather than heating the entire distillation tower or waste liquid storage container as in the traditional method, which greatly reduces unnecessary energy consumption. This targeted heating strategy can significantly improve the efficiency of the distillation process. Reducing energy consumption is in line with the environmental protection concept of energy conservation and emission reduction; the designed annular opening liquid dispersion port 103 and the conical heating area heating plate 104 ensure that heat can be absorbed by the waste liquid in a more concentrated and efficient manner, reducing heat loss and improving the utilization rate of thermal energy; by allowing the waste liquid to circulate and continuously pass through the heating plate 104, the continuity and stability of the waste liquid treatment can be enhanced, and the waste liquid deposition can be avoided; in summary, this technical solution not only significantly improves the efficiency and speed of waste liquid treatment, but also performs well in energy conservation and emission reduction and optimizing resource utilization, and is an important progress in the field of waste liquid treatment.

[0052] like Figure 3 As shown, the power structure includes a motor 107 installed at the bottom of the first storage chamber 101, and a rotating shaft 108 is provided at the output end of the motor 107. The rotating shaft 108 passes through the first storage chamber 101 and the second storage chamber 102. A plurality of fan plates 109 for promoting the flow of waste liquid are provided on the rotating shaft 108 in the channel;

[0053] The first storage chamber 101 and the second storage chamber 102 are connected via a plurality of connecting rods 106 , and the liquid guide hole 105 is inclined in a direction away from the rotation shaft 108 .

[0054] In detail, the connecting rod 106 can connect the first storage chamber 101 and the second storage chamber 102 to fix their positions. The motor 107 can drive the multiple fan plates 109 to rotate through the rotating shaft 108. The fan plates 109 can provide centrifugal driving force for the waste liquid in the channel, so that the waste liquid flows upward along the channel and is discharged to the heating plate 104 through the liquid dispersion port 103, thereby providing power for the circulation of the waste liquid.

[0055] Since the liquid guide hole 105 is inclined, when the waste liquid flows into the channel through the liquid guide hole 105, the flow direction of the waste liquid is the same as the direction in which the fan plate 109 provides the driving force for the waste liquid. This makes it convenient for the fan plate 109 to directly accelerate the flow of the waste liquid without changing the flow direction of the waste liquid.

[0056] It should be noted that the waste liquid rises in the channel under the push of the fan plate 109 . When the waste liquid level rises to the height of the liquid diffusion port 103 , the waste liquid can naturally flow through the liquid diffusion port 103 onto the heating plate 104 .

[0057] like Figure 4 As shown, the guide structure 200 includes a fixed cylinder 201 fixed on the top of the first storage chamber 101, the fixed cylinder 201 is connected to the inside of the first storage chamber 101, a guide pipe 202 and a partition 203 are provided in the middle of the fixed cylinder 201, the two ends of the guide pipe 202 are respectively located at the upper and lower sides of the partition 203, the guide pipe 202 is fixed on the partition 203, the partition 203 is rotatably mounted on the inner wall of the fixed cylinder 201, the guide pipe 202 is used to transport the gas of the waste liquid distillation, the partition 203 is used to separate the internal space of the fixed cylinder 201, and the rotating shaft 108 is fixedly connected to the partition 203;

[0058] The guide tube 202 is conical in shape, and the conical opening faces the distillation structure 100. The projection of the guide tube 202 on the horizontal plane is vortex-shaped. When the shaft 108 drives the guide tube 202 to rotate, the rotation direction of the guide tube 202 is the same as its spiral direction.

[0059] In detail, the fixed cylinder 201 is fixed on the first storage chamber 101, the distillation area in the heating plate 104 is opposite to the fixed cylinder 201, the flow guide tube 202 is used to separate the internal space of the fixed cylinder 201, the lower space of the flow guide tube 202 is connected with the first storage chamber 101, and the upper space of the fixed cylinder 201 is connected with the condensation structure 300, and the distilled gas can flow into the condensation structure 300 through the flow guide tube 202.

[0060] The rotating shaft 108 can drive the partition 203 and the guide tube 202 to rotate. Due to the limitation of the shape and rotation direction of the guide tube 202, when the gas enters the guide tube 202, other impurity liquids entrained in the gas move toward the inner wall of the guide tube 202 due to the action of gravity, and the impurity liquids are adsorbed on the inner wall of the guide tube 202. As the guide tube 202 rotates, the impurity liquids are affected by the centrifugal force and move outward along the vortex direction of the guide tube 202, that is, the impurity liquids move toward the inlet position of the distilled gas. At this time, as the impurity liquids move, their centrifugal radius increases, thereby accelerating the discharge of the impurity liquids, and the impurity liquids fall back into the distillation structure 100, while the distilled gas is subject to a small centrifugal action provided by the guide tube 202, so it can pass through the guide tube 202 normally, thereby achieving the purification of the distilled gas.

[0061] like Figure 5 As shown, the condensation structure 300 includes a condensation chamber 301 fixedly sleeved on the outer wall of the fixed cylinder 201, a fixed slot plate 302 is arranged in the condensation chamber 301, a condensation pipe 303 is arranged in the fixed slot plate 302, the output end of the guide pipe 202 is connected to the fixed slot plate 302 and distillation gas is supplied into the fixed slot plate 302, and the condensation pipe 303 condenses the distillation gas;

[0062] The fixed slot plate 302 is ring-shaped, with its opening facing downward.

[0063] In detail, the condensation chamber 301 is cylindrical in shape, which is fixedly mounted on the outer wall of the fixed cylinder 201. The fixed slot plate 302 is coaxially arranged in the condensation chamber 301, and the fixed slot plate 302 is connected to the guide tube 202. When the guide tube 202 rotates, it can drive the fixed slot plate 302 to rotate synchronously. The condensation tube 303 in the fixed slot plate 302 is used for condensing and recovering the distilled gas.

[0064] like Figure 5 As shown, it also includes a straight tube 304, which is along the radial direction of the condensing chamber 301, one end of the straight tube 304 is connected to the output end of the guide tube 202, and the other end of the straight tube 304 is connected to the fixed slot plate 302;

[0065] The input end of the flow guide tube 202 is located between the output end of the straight tube 304 and the axis of the fixed tube 201 .

[0066] In detail, the length of the straight tube 304 is larger than the vortex radius of the guide tube 202 at the input end of the guide tube 202. Therefore, when the guide tube 202 drives the straight tube 304 to rotate, the linear velocity of the output end of the straight tube 304 is faster. At this time, due to the speed difference between the output end of the straight tube 304 and the input end of the guide tube 202, the gas can be automatically sucked into the guide tube 202 and discharged into the fixed groove plate 302 through the straight tube 304, thereby achieving the purpose of pressurized air intake. At this time, the pressure in the distillation structure 100 decreases, while the pressure in the condensation chamber 301 increases, so that the distillation work is carried out under negative pressure to reduce the distillation temperature, while the condensation is carried out under high pressure to increase the condensation speed.

[0067] The pressure difference between the distillation structure 100 and the condensation structure 300 is affected by the rotation speed of the draft tube 202 and the length of the straight tube 304 .

[0068] like Figure 5 As shown, a support ring 305 and a liquid-absorbing cotton 306 are provided at the bottom opening of the fixed slot plate 302. The support ring 305 is used to support the liquid-absorbing cotton 306. The gas in the fixed slot plate 302 flows downward into the liquid-absorbing cotton 306 through the bottom opening of the fixed slot plate 302.

[0069] A plurality of pressure rollers 307 are rotatably disposed in the condensation chamber 301 , and the pressure rollers 307 are used to roll the liquid-absorbing cotton 306 .

[0070] In detail, the condensed liquid and the uncondensed gas in the fixed groove plate 302 can all enter the liquid absorbent cotton 306, thereby achieving comprehensive absorption of the distilled gas and improving the capture and recovery effect. When the fixed groove plate 302 rotates, it can drive the liquid absorbent cotton 306 to rotate synchronously, and the pressure roller 307 moves relative to the liquid absorbent cotton 306. The pressure roller 307 continuously rolls the liquid absorbent cotton 306, thereby quickly squeezing out the liquid adsorbed on the liquid absorbent cotton 306, which is convenient for liquid recovery and allows the liquid absorbent cotton 306 to continue to adsorb the liquid in the fixed groove plate 302. The support ring 305 is used to cooperate with the pressure roller 307 and squeeze the liquid absorbent cotton 306.

[0071] like Figure 5 As shown, it also includes a turntable 308 rotatably mounted on the outer wall of the fixed cylinder 201 , and the turntable 308 is connected to the support ring 305 .

[0072] In detail, the turntable 308 provides support for the fixed slot plate 302 , the condenser tube 303 , the support ring 305 and the absorbent cotton 306 .

[0073] like Figure 6 to Figure 7As shown, the drainage structure 400 includes a drainage chamber 401, a circular cavity and an arc-shaped cavity 402 are arranged in the drainage chamber 401, and the circular cavity and the arc-shaped cavity 402 are coaxial, a rotating wheel 403 is rotatably arranged in the circular cavity, a plurality of guide grooves are opened on the rotating wheel 403, and the length direction of the guide groove is along the radial direction of the rotating wheel 403, a baffle 404 is slidably arranged in the guide groove, and the baffle 404 is connected to the rotating wheel 403 by a spring 405, when the baffle 404 moves into the circular cavity, the inner wall of the circular cavity blocks the baffle 404, and when the baffle 404 moves into the arc-shaped cavity 402, the baffle 404 moves outward and abuts against the inner wall of the arc-shaped cavity 402;

[0074] The inner wall of the circular cavity is in sliding contact with the outer wall of the rotating wheel 403 , the top of the drainage chamber 401 is connected to the condensation chamber 301 through a vertical long tube 406 , and a drainage pipe 407 for discharging condensed liquid is provided at the bottom of the drainage chamber 401 .

[0075] In detail, the rotating wheel 403 occupies the entire circular cavity, and the arc-shaped cavity 402 is used for the discharge of condensed liquid. As the pressure roller 307 squeezes the absorbent cotton 306, the condensed liquid enters the condensation chamber 301 and flows into the long tube 406. The liquid in the long tube 406 flows downward into the arc-shaped cavity 402. As the amount of liquid increases, the pressure of the liquid on the baffle 404 in the arc-shaped cavity 402 increases. The liquid can push the rotating wheel 403 to rotate through the baffle 404 in the arc-shaped cavity 402, and the rotating wheel 403 drives multiple baffles 404 to rotate synchronously. When the baffle 404 in the circular cavity moves into the arc-shaped cavity 402, the spring 405 pushes the baffle 404 to move outward and abut against the inner wall of the arc-shaped cavity 402. At this time, the two adjacent baffles 404 separate the space between them independently. As the rotating wheel 403 rotates, the space can carry the liquid to the position of the drain pipe 407 and discharge the liquid through the drain pipe 407, thereby realizing the liquid discharge work.

[0076] The inner wall of one end of the arc-shaped cavity 402 is set as an inclined surface. When the baffle 404 moves to the inclined surface position, the inclined surface can push the baffle 404 to retract into the guide groove, and the spring 405 is compressed, thereby realizing the continuous rotation of the wheel 403 and the liquid extraction work.

[0077] It should be noted that the pressure in the condensation chamber 301 can also promote the liquid, and a sufficient amount of liquid is always retained in the long tube 406, thereby preventing the gas in the condensation chamber 301 from being discharged through the drainage structure 400, thereby achieving the purpose of only draining the liquid without exhausting the gas. At the same time, this structure can prevent external gas from entering the condensation chamber 301.

[0078] like Figure 6 As shown, a hollow shaft 408 is rotatably inserted in the middle of the discharge chamber 401 , the rotating wheel 403 is mounted on the hollow shaft 408 , and the guide groove on the rotating wheel 403 extends to the inside of the hollow shaft 408 .

[0079] In detail, when the baffle 404 slides in the guide groove, if the baffle 404 is not connected to the inside of the hollow shaft 408, the space inside the wheel 403 will change and cause the air pressure to change, which will affect the movement of the baffle 404. The way in which the guide groove is connected to the hollow shaft 408 can ensure that the air pressure in the guide groove is normal.

[0080] like Figure 6 As shown, a plurality of clamping rods 409 are arranged on the outer wall of the hollow shaft 408 outside the drainage chamber 401. The clamping rods 409 are arranged along the radial direction of the hollow shaft 408. An arc plate 410 is horizontally slidably arranged on the outer wall of the drainage chamber 401. The arc plate 410 is provided with an arc groove for clamping the end of the clamping rod 409. The arc plate 410 is connected to the drainage chamber 401 by a spring piece 411.

[0081] In detail, the arc plate 410 uses the pushing action of the spring piece 411 to clamp a clamping rod 409 on the hollow shaft 408. At this time, the hollow shaft 408 cannot rotate. As the liquid in the long tube 406 increases, its pressure increases. When the pressure overcomes the elastic force of the spring piece 411, the hollow shaft 408 drives a clamping rod 409 to disengage from the arc groove on the arc plate 410 and rotate the hollow shaft 408. The next clamping rod 409 moves to the arc plate 410 and slides into the arc groove, thereby clamping the hollow shaft 408 again through the arc plate 410. During the rotation of the hollow shaft 408, it can discharge part of the liquid through the discharge pipe 407.

[0082] It should be noted that, as the hollow shaft 408 rotates, there is at least one clamping rod 409 on the arc plate 410 .

[0083] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
