Description

Technical Field

[0001] The invention belongs to the technical field of waste liquid treatment, and in particular relates to a heat pump system with heat source recycling. Background Art

[0002] Heat pump technology is an efficient, environmentally friendly and energy-saving technology that can be widely used in industrial production fields such as chemical industry, low-grade thermal energy utilization, seawater desalination, and sewage treatment. After the sewage is evaporated and concentrated by the heat pump, distilled water that meets the discharge standards can be extracted from it. The distilled water can be discharged directly, and the remaining concentrate can be discharged to the sewage treatment plant for treatment, which can greatly reduce the sewage treatment cost of the enterprise.

[0003] When the heat pump system treats sewage, it first passes the sewage liquid into the distillation kettle. Under the low pressure state of the distillation kettle, the boiling point of the liquid is reduced, and only a small amount of steam is needed to evaporate a large amount of water in the liquid. However, since the distillation kettle is in a low pressure state, there is a pressure difference between the distillation kettle and the gas-liquid separator. Under the action of negative pressure, the steam generated inside the distillation kettle is easy to carry mist into the separator. Therefore, a wire mesh demister needs to be installed. When the gas with mist rises through the wire mesh at a certain speed, due to the inertia of the rising mist, the mist collides with the wire mesh filaments and is attached to the surface of the filaments. The diffusion of the mist on the surface of the filaments and the gravity sedimentation of the mist cause the mist to form larger droplets that flow along the filaments to the intersection of the two filaments. The wettability of the filaments, the surface tension of the liquid and the capillary action of the filaments make the droplets larger and larger until the aggregated droplets are so large that the gravity generated by themselves exceeds the combined force of the gas rising force and the liquid surface tension, and the droplets separate from the filaments and fall.

[0004] The heat pump system of the prior art has the following problems: first, the heat source utilization rate of the heat pump system of the prior art is poor; second, the existing wire mesh demisters rely on the water droplets to slowly condense themselves. Under the action of the rising force of the gas, small droplets tend to drip slowly, which can easily cause the wire mesh demister to be blocked. For example, the patent with announcement number CN209286885U absorbs the droplets on the wire mesh through a sponge, but when the gas and liquid passing through the wire mesh have the characteristics of high density and high viscosity, the time for the sponge to absorb the liquid increases, and the absorption efficiency of the sponge decreases, which can easily cause the wire mesh to be blocked. Summary of the invention

[0005] The purpose of the present invention is to provide a liquid fuel sensor device to solve the technical problems in the prior art in view of the shortcomings of the prior art.

[0006] The object of the present invention can be achieved by the following technical solution: A heat pump system with heat source recycling, characterized in that the system comprises the following steps: Step S1: starting the negative pressure component to make the pressure in the distillation kettle negative, then passing the feed liquid into the distillation kettle through the liquid inlet, and the boiling point of the feed liquid in the distillation kettle is reduced; Step S2: a jacket is installed on the distillation kettle, and first steam generated by a steam generator is passed into the jacket of the distillation kettle. The first steam exchanges heat with the feed liquid inside the distillation kettle, and the feed liquid evaporates to generate second steam; Step S3: The first steam is liquefied into a first condensate having a certain temperature after heat exchange with the feed liquid. The first condensate is pumped into the steam generator through the pump body. The heat of the first condensate can be used again by the steam generator. The second steam is passed into the separator. Step S4: When the second steam is passed into the separator, the screen in the separator removes the mist in the second steam, and then the enhanced sponge absorbs the small droplets condensed on the screen, and the connecting rod pulls one side of the enhanced sponge to increase the pore size of the enhanced sponge and improve the adsorption efficiency of the enhanced sponge. At the same time, the pressure roller presses the other side of the enhanced sponge to quickly discharge the water adsorbed by the enhanced sponge, and the second steam is discharged from the separator and passed into the steam condenser; Step S5: After the second steam enters the steam condenser, the water outlet and the water inlet on the steam condenser are closed, and the second steam inside the steam condenser is all passed into the refrigerant evaporator and exchanges heat with the refrigerant evaporator; Step S6: the refrigerant evaporator absorbs the heat of the second steam and promotes the state change of the refrigerant. The second steam entering the refrigerant evaporator exchanges heat with the refrigerant. The liquid refrigerant absorbs the heat of the steam and is converted into a high-temperature and high-pressure gaseous refrigerant. At the same time, the second steam is condensed into a third condensate. The vacuum component extracts the third condensate. The high-temperature and high-pressure gaseous refrigerant is passed into the refrigerant condenser inside the steam generator through a filter. When the refrigerant evaporator is not sufficient to condense and process all the generated second steam, the water outlet and the water inlet are opened, and the steam condenser condenses the excess second steam. The steam condenser condenses the second steam into a second condensate, and the second condensate is extracted from the steam condenser through the vacuum component. Step S7: The refrigerant condenser inside the steam generator converts the high-temperature and high-pressure gaseous refrigerant into liquid, while dissipating heat, which is absorbed and utilized by the steam generator, thereby improving the heat utilization rate of the heat pump system; Step S8: the liquid refrigerant in the refrigerant condenser is depressurized through the pressure relief valve and enters the preheater for preheating, and the preheated refrigerant is passed into the refrigerant evaporator for circulation; Step S9: The steam generator generates first steam by utilizing the heat of the first condensate generated by the thermal liquefaction of the first steam and the feed liquid and the heat of the high-temperature gaseous refrigerant generated by the heat exchange between the second steam and the refrigerant, and passes the first steam into the jacket.

[0007] As a further optimization or improvement of this solution, step S3 specifically includes the following steps: Step S31: Connect a water supply pipe to the pipeline near the pump body, and install a flow sensor on the water supply pipe; Step S32: The flow sensor detects the flow rate of the first condensate entering the steam generator. When the flow rate decreases, high-temperature water is added to the steam generator through the water supply pipe.

[0008] As a further optimization or improvement of the present solution, the separator comprises a defoaming cylinder and an oblique feed port and an exhaust port installed on the defoaming cylinder, the defoaming cylinder is connected to the distillation kettle through the oblique feed port, and is connected to the steam condenser through the exhaust port, and the interior of the defoaming cylinder is divided into a de-impurity chamber, a buffer chamber, a defoaming chamber and a transmission chamber from bottom to top; A spiral screen cylinder is installed in the impurity removal chamber, and screen holes are provided on the inner wall of the spiral screen cylinder. The impurity removal chamber is connected with the inclined feed port. A defoaming cylinder is installed in the defoaming chamber, and a wire mesh and a reinforced sponge are installed in the defoaming cylinder from bottom to top, and the reinforced sponge is attached to the wire mesh. A motor is installed in the transmission chamber, and the motor is connected to the rotating rod for transmission. The motor drives the rotating rod to rotate. A connecting column is coaxially installed on the rotating rod, and a connecting rod and a pressure roller at different heights in the same plane are installed on the connecting column. The pressure roller presses the reinforced sponge, and the connecting rod pulls the reinforced sponge. The defoaming cylinder is connected with the exhaust port, and a buffer chamber is separated from the impurity removal chamber and the defoaming chamber.

[0009] As a further optimization or improvement of the present solution, a bottom ring groove and a top ring groove are respectively opened in the defoaming cylinder, an annular block is installed on the bottom edge of the reinforced sponge, a top buckle is installed on the top of the reinforced sponge, and a sliding buckle is installed on the connecting rod, one end of the sliding buckle is slidably matched with the top ring groove, and the other end is connected with the top buckle.

[0010] As a further optimization or improvement of this solution, a water tank is installed in the transmission cavity, and a spray pipe is installed on the connecting column. The spray pipe is located between the reinforced sponge and the wire mesh. The nozzle on the spray pipe faces the wire mesh. The spray pipe is connected to the water tank through the connecting column and the internal pipeline of the rotating rod. The spray pipe and the pressure roller are installed on the same plane.

[0011] As a further optimization or improvement of this solution, the vacuum component is a vacuum pump and the preheater is an electric heater.

[0012] As a further optimization or improvement of the present solution, a water outlet and a water inlet are respectively installed on the steam condenser, and circulating water is respectively added into and discharged from the steam condenser through the water outlet and the water inlet.

[0013] As a further optimization or improvement of this solution, a plate heat exchanger is connected in series between the steam condenser and the refrigerant evaporator.

[0014] Beneficial effects of the present invention: (1) The steam generator of the present invention can recycle the heat of the condensed water and high-temperature gaseous refrigerant after the first steam is liquefied, greatly improve the utilization rate of the heat source, reduce the energy consumption of the steam generator, and greatly optimize the heat pump system.

The connecting rod pulls up one end of the reinforcing sponge through a sliding buckle to control the size of the gaps in the reinforcing sponge, thereby improving the absorption efficiency of the reinforcing sponge, allowing the reinforcing sponge to quickly absorb the water droplets condensed from the mist, thereby reducing the probability of screen clogging. At the same time, the pressure roller on the connecting column presses the pressure roller at the other end to quickly discharge the liquid absorbed by the reinforcing sponge.

When the pressure roller presses the top of the reinforced sponge, the spray pipe separates the wire mesh and the reinforced sponge to prevent the pressure roller from pressing the bottom of the reinforced sponge into the wire mesh and causing damage to the reinforced sponge.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 6 , a heat pump system with heat source recycling, characterized in that the system comprises the following steps: Step S1: starting the negative pressure component to make the pressure in the distillation kettle 1 negative, then passing the feed liquid into the distillation kettle 1 through the liquid inlet 2, so that the boiling point of the feed liquid in the distillation kettle 1 is reduced; Step S2: a jacket is installed on the distillation kettle 1, and the first steam generated by the steam generator 10 is passed into the jacket of the distillation kettle 1, and the first steam exchanges heat with the feed liquid inside the distillation kettle 1, and the feed liquid evaporates to generate second steam; Step S3: The first steam is liquefied into a first condensate having a certain temperature after heat exchange with the feed liquid. The first condensate is pumped into the steam generator 10 through the pump body 12. The heat of the first condensate can be used again by the steam generator 10. The second steam is passed into the separator 4. Step S4: When the second steam is passed into the separator 4, the screen 413 in the separator 4 removes the mist in the second steam, and then the enhanced sponge 414 adsorbs the small droplets condensed on the screen 413, and the connecting rod 420 pulls one side of the enhanced sponge 414 to increase the pore size of the enhanced sponge 414 and the adsorption efficiency of the enhanced sponge 414. At the same time, the pressure roller 419 presses the other side of the enhanced sponge 414 to quickly discharge the water adsorbed by the enhanced sponge 414, and the second steam is discharged from the separator 4 and passed into the steam condenser 5; Step S5: After the second steam enters the steam condenser 5, the water outlet 6 and the water inlet 7 on the steam condenser 5 are closed, and the second steam inside the steam condenser 5 is all passed into the refrigerant evaporator 8 and exchanges heat with the refrigerant evaporator 8; Step S6: the refrigerant evaporator 8 absorbs the heat of the second steam and promotes the state change of the refrigerant. The second steam entering the refrigerant evaporator 8 exchanges heat with the refrigerant. The liquid refrigerant absorbs the heat of the steam and is converted into a high-temperature and high-pressure gaseous refrigerant. At the same time, the second steam is condensed into a third condensate. The vacuum component 11 extracts the third condensate. The high-temperature and high-pressure gaseous refrigerant passes through the filter 14 and enters the refrigerant condenser inside the steam generator 10. When the refrigerant evaporator 8 is not sufficient to condense and process all the generated second steam, the water outlet 6 and the water inlet 7 are opened, and the steam condenser 5 condenses the excess second steam. The steam condenser 5 condenses the second steam into a second condensate, and the second condensate is extracted from the steam condenser 5 through the vacuum component 11. Step S7: The refrigerant condenser inside the steam generator 10 converts the high-temperature and high-pressure gaseous refrigerant into liquid state, while dissipating heat, which is absorbed and utilized by the steam generator 10, thereby improving the heat utilization rate of the heat pump system; Step S8: the liquid refrigerant in the refrigerant condenser is depressurized through the pressure relief valve 13 and enters the preheater 9 for preheating, and the preheated refrigerant is passed into the refrigerant evaporator 8 for circulation; Step S9: the steam generator 10 generates first steam by utilizing the heat of the first condensate generated by the thermal liquefaction of the first steam and the feed liquid and the heat of the high-temperature gaseous refrigerant generated by the heat exchange between the second steam and the refrigerant, and passes the first steam into the jacket.

[0029] Specifically, a water outlet 6 and a water inlet 7 are respectively installed on the steam condenser 5, and circulating water is respectively added into the steam condenser 5 and discharged through the water outlet 6 and the water inlet 7.

[0030] It should be noted that the present invention can realize heat source recovery through two circulation lines. In the first line, after the feed liquid is passed into the distillation kettle 1, most of the water inside the feed liquid is evaporated by the distillation kettle 1 to produce a second steam, and the concentrated feed liquid is discharged from the distillation kettle 1. The second steam is successively passed into the steam condenser 5 and the refrigerant evaporator 8, and the heat of the second steam is recycled by the steam generator 10; in the second line, the condensed water generated by the first steam in the inner cavity of the distillation kettle 1 by the steam generator 10 can enter the steam generator 10 again through the pump body 12 for recycling.

[0031] The steam generator 10 of the present invention can recycle the heat of the condensed water and high-temperature gaseous refrigerant after the first steam is liquefied, greatly improve the utilization rate of the heat source, reduce the energy consumption of the steam generator 10, and greatly optimize the heat pump system. The present invention significantly reduces energy consumption by recovering and utilizing the waste heat of the secondary steam. Compared with traditional evaporation technology, the present invention can save a lot of energy and improve energy utilization; when treating waste liquid, the present invention will not produce secondary pollution and meet environmental protection requirements. The present invention can reduce the amount of waste liquid discharged and reduce pollution to the environment through efficient waste liquid treatment. The present invention can be applied to the treatment of a variety of waste liquids, including radioactive waste liquids, industrial waste liquids, etc. The present invention has low operating costs and low maintenance costs. The heat pump system has high economic benefits, high system stability, strong reliability, and can operate normally in various harsh environments.

[0032] See also Figure 1 , the step S3 specifically comprises the following steps: Step S31: Connect the water supply pipe 3 to the pipeline near the pump body 12, and install a flow sensor on the water supply pipe 3; Step S32: the flow sensor detects the flow rate of the first condensate entering the steam generator 10 . When the flow rate decreases, high-temperature water is added into the steam generator 10 through the water supply pipe 3 .

[0033] It should be noted that the high-temperature water added by the water supply pipe 3 is water outside the system. Since water will be consumed when circulating in the heat pump system, high-temperature water is added to the system through the water supply pipe 3 to balance the water circulation of the system and effectively prevent high-pressure fluctuations caused by water temperature fluctuations.

[0034] See also Figure 2-Figure 7The separator 4 includes a defoaming cylinder 401 and an oblique feed port 403 and an exhaust port 402 installed on the defoaming cylinder 401. The defoaming cylinder 401 is connected to the distillation kettle 1 through the oblique feed port 403 and is connected to the steam condenser 5 through the exhaust port 402. The interior of the defoaming cylinder 401 is divided into a defoaming chamber 409, a buffer chamber 406, a defoaming chamber 407 and a transmission chamber 408 from bottom to top; a spiral screen drum 404 is installed in the defoaming chamber 409, and a screen hole 405 is provided on the inner wall of the spiral screen drum 404. The defoaming chamber 409 is connected to the oblique feed port 403. A defoaming cylinder 415 is installed in the defoaming chamber 407. The defoaming cylinder 415 A wire mesh 413 and a reinforced sponge 414 are installed in sequence from bottom to top inside, and the reinforced sponge 414 is attached to the wire mesh 413, a motor 410 is installed inside the transmission chamber 408, the motor 410 is in transmission connection with the rotating rod 412, the motor 410 drives the rotating rod 412 to rotate, a connecting column 418 is coaxially installed on the rotating rod 412, a connecting rod 420 and a pressure roller 419 at different heights in the same plane are installed on the connecting column 418, the pressure roller 419 presses the reinforced sponge 414, the connecting rod 420 pulls the reinforced sponge 414, the defoaming cylinder 415 is connected to the exhaust port 402, and a buffer chamber 406 is separated from the defoaming chamber 409 and the defoaming chamber 407.

[0035] Specifically, a bottom ring groove 417 and a top ring groove 416 are respectively provided in the defoaming cylinder 415, a ring block 424 is installed on the bottom edge of the reinforced sponge 414, a top buckle 423 is installed on the top of the reinforced sponge 414, and a sliding buckle 421 is installed on the connecting rod 420, one end of the sliding buckle 421 is slidably matched with the top ring groove 416, and the other end is matched and connected with the top buckle 423.

[0036] It should be noted that when the separator 4 is in use, the steam generated by the evaporation of the liquid inside the distillation kettle 1 is passed into the defoaming cylinder 401 through the inclined feed port 403. At this time, the steam passes through the impurity removal chamber 409, the buffer chamber 406 and the defoaming chamber 407 in turn, and is finally transported to the steam condenser 5 through the exhaust port 402.

[0037] The steam first enters the spiral screen drum 404 inside the impurity removal chamber 409. After entering the spiral screen drum 404, the steam rotates along the spiral blades on the inner wall of the spiral screen drum 404 and generates centrifugal force, and the impurities inside the steam are thrown out of the spiral screen drum 404 through the screen holes 405 under the action of the centrifugal force, thereby reducing the impurity content in the steam and reducing the phenomenon of impurities blocking the wire mesh 413. After passing through the spiral screen drum 404, the steam enters the buffer chamber 406. After the steam enters the buffer chamber 406, the vortex generated by the steam is buffered, so that the steam enters the wire mesh 413 in a steady state, thereby improving the defoaming efficiency of the wire mesh 413; when the steam enters the defoaming chamber 407, the steam first passes through the wire mesh 413, and the mist mixed in the steam is attached to the wire mesh 413, and the mist attached to the wire mesh 413 condenses into water droplets, which are absorbed by the enhanced sponge 414, thereby reducing the probability of clogging the wire mesh 413.

[0038] When the tiny water droplets in the mist have the characteristics of high density and high viscosity, the absorption efficiency of the enhanced sponge 414 decreases, and the water absorption time of the enhanced sponge 414 increases. If there are too many mists mixed with steam, the screen 413 will still be blocked. Figure 5 and Figure 6 The present invention starts the motor 410, and the motor 410 drives the rotating rod 412 and the connecting column 418 to rotate synchronously through the gears. The connecting column 418 drives the connecting rod 420 to rotate. The connecting rod 420 pulls one end of the enhanced sponge 414 through the slider 421 to control the gap size of the enhanced sponge 414, improve the absorption efficiency of the enhanced sponge 414, and enable the enhanced sponge 414 to quickly absorb the water droplets condensed from the mist, thereby reducing the probability of clogging of the screen 413. At the same time, the pressure roller 419 on the connecting column 418 presses the pressure roller 419 at the other end to quickly discharge the liquid absorbed by the enhanced sponge 414.

[0039] See also Figure 5-Figure 8 A water tank 411 is installed in the transmission cavity 408, and a spray pipe 422 is installed on the connecting column 418. The spray pipe 422 is located between the reinforced sponge 414 and the wire mesh 413. The nozzle on the spray pipe 422 faces the wire mesh 413. The spray pipe 422 is connected to the water tank 411 through the connecting column 418 and the internal pipeline of the rotating rod 412. The spray pipe 422 and the pressure roller 419 are installed on the same plane.

[0040] It should be noted that if the mist contains acidic substances, after the mist enters the screen 413, the moisture in the steam dissolves the acidic substances in the mist into weak acid, and corrodes the screen 413. In order to avoid the above phenomenon, the present invention installs a spray pipe 422 on the connecting column 418, and connects the spray pipe 422 to the water tank 411 through the connecting column 418 and the internal pipeline of the rotating rod 412. When the motor 410 drives the rotating rod 412 to rotate, the water tank 411 supplies water to the spray pipe 422 through the water pump, so that the spray pipe 422 flushes the screen 413 through the water spray hole at the bottom, and washes away the mist containing acidic substances inside the screen 413, so as to prevent the acidic substances in the mist from corroding the screen 413.

[0041] Specifically, in order to ensure the absorption efficiency of the enhanced sponge 414, it is generally necessary to install the enhanced sponge 414 on the screen 413, see Figure 7 and Figure 8However, since the reinforcing sponge 414 is attached to the wire mesh 413, when the pressure roller 419 presses the reinforcing sponge 414, the bottom of the reinforcing sponge 414 is easily embedded in the wire mesh 413, damaging the reinforcing sponge 414, and making it difficult to clean the sponge scraps inside the wire mesh 413. In order to avoid the above situation, the spray pipe 422 is installed between the wire mesh 413 and the reinforcing sponge 414, and the spray pipe 422 is located at the bottom of the pressure roller 419. When the pressure roller 419 presses the top of the reinforcing sponge 414, the spray pipe 422 separates the wire mesh 413 and the reinforcing sponge 414, preventing the pressure roller 419 from pressing the bottom of the reinforcing sponge 414 into the wire mesh 413, causing damage to the reinforcing sponge 414.

[0042] It should be noted that a heat dissipation hole 425 is provided on the top of the defoaming cylinder 401 for dissipating heat during operation of the motor 410 .

[0043] See also Figure 1 The vacuum component 11 is a vacuum pump, and the preheater 9 is an electric heater.

[0044] It should be noted that the vacuum component 11 preferably uses a vacuum pump, and an ejector can also be used instead of the vacuum component 11; the preheater 9 preferably uses an electric heater.

[0045] See also Figure 1 A plate heat exchanger is connected in series between the steam condenser 5 and the refrigerant evaporator 8.

[0046] It should be noted that in order to increase the heating capacity of the heat pump system, a small evaporator is connected in series between the steam condenser 5 and the refrigerant evaporator 8, and the evaporator is a plate heat exchanger.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
