Description

Technical Field

[0001] The present invention relates to the technical field of pipeline energy storage, and in particular to a highly efficient and intelligent cold and heat storage and transportation equipment. Background Art

[0002] The insulated pipe of a thermal power plant is a device used to transmit steam or cooling water. It is composed of a protective layer and an insulation layer. The fluid is transmitted to the destination through the hollow pipe inside the insulation layer. At present, the energy storage devices of thermal power plants, the energy storage devices at the cooling and heating ends, and the energy storage devices at the energy consumption end are above-ground tanks or pits, which occupy a large area and have large heat losses. Energy exchange and transmission require the construction of additional pipelines, and the investment cost is huge.

[0003] Since the existing heat storage pipeline reduces the flow rate of the fluid to increase the energy transfer rate through fluid momentum loss, however, the flow rate of the fluid in the thermal power plant will change due to factors such as the external environment or operating power, which will reduce the flow pressure of the fluid and reduce the effective energy transfer rate. Summary of the invention

[0004] Based on this, it is necessary to provide a high-efficiency intelligent cold and heat storage and transportation equipment to address the problem that the existing high-efficiency intelligent cold and heat storage and transportation equipment is easily prone to reduce the effective energy transfer rate due to changes in fluid flow.

[0005] A highly efficient and intelligent cold and heat storage and transportation equipment comprises a protection tank and a monitoring system, wherein the monitoring system is installed inside the protection tank, one end of the monitoring system passes through the protection tank, an energy storage steel pipe is fixedly connected to the inside of the protection tank, a fluid guiding mechanism is installed on the surface of the protection tank, one end of the fluid guiding mechanism passes through the protection tank in turn and extends to the inside of the energy storage steel pipe.

[0006] Furthermore, the fluid guiding mechanism includes a two-way infusion pump fixedly connected to the surface of the protection tank, one end of the two-way infusion pump is connected to the energy storage steel pipe, one end of the two-way infusion pump is fixedly connected and connected to a first liquid guide tube, one end of the first liquid guide tube penetrates into the interior of the protection tank, the surface of the first liquid guide tube is fixedly connected and connected to an elastic liquid storage bag, both ends of the elastic liquid storage bag are fixedly connected to guide plates that are slidably connected to the protection tank and the energy storage steel pipe, and the guide plates are staggered with the inlet and outlet of the protection tank.

[0007] In one of the embodiments, the fluid guiding mechanism can not only autonomously regulate the pressure and temperature of the passing fluid when it passes through, so as to improve the ability of the conveying equipment to store cold and heat efficiently and intelligently, thereby solving the problem that the existing efficient and intelligent cold and heat storage conveying equipment is easily reduced in the effective energy transfer rate due to changes in the fluid flow rate; at the same time, an elastic liquid storage bag connected to the energy storage fluid is used, which can not only indirectly increase the contact area between the energy storage fluid and the passing fluid, further improve the cold and heat storage performance of the passing fluid, but also use the reflux guiding component to accelerate the blending rate of the energy storage fluid inside the energy storage steel pipe and the energy storage fluid inside the elastic liquid storage bag while ensuring the expansion degree of the elastic liquid storage bag, so that the temperature of the energy storage fluid is more uniform, and the cold and heat storage performance of the passing fluid is further improved.

[0008] Furthermore, the fluid guiding mechanism also includes a positioning component, which also includes two circular frames fixedly connected between the protection tank and the energy storage steel pipe, and a guide port is opened on the surface of the circular frame, and the guide port is arranged between two adjacent guide plates, and the guide port is staggered with the first liquid guide tube and the elastic liquid storage bag.

[0009] In one of the embodiments, the positioning component can not only effectively limit the moving trajectory of the guide plate to ensure that the guide plate can stably guide the passing fluid, but also the positioning component can cooperate with the guide plate to limit the flow path of the passing fluid to ensure that the passing fluid can evenly cover the surface of the energy storage steel pipe.

[0010] Furthermore, the fluid guiding mechanism also includes a reflux guiding assembly, which includes a reflux cylinder fixedly connected to the inside of the protection tank, one end of the reflux cylinder is connected to the energy storage steel pipe, the surface of the reflux cylinder is fixedly connected and connected to a second liquid guide tube distributed in a ring shape, one end of the second liquid guide tube sequentially penetrates the protection tank and the adjacent circular frame and is fixedly connected and connected to the adjacent elastic liquid storage bag, the inside of the reflux cylinder is slidably connected with a flow limiting disk in contact with the second liquid guide tube, the cross-sectional shape of the flow limiting disk is a right-angled trapezoid, the distance between the second liquid guide tube at the top and the flow limiting disk is set to A, the distance between the second liquid guide tube at the bottom and the flow limiting disk is set to B, the length ratio between A and B is one to eight, one end of the flow limiting disk is fixedly connected to an electric cylinder, one end of the electric cylinder penetrates the reflux cylinder and is fixedly connected to the protection tank.

[0011] In one of the embodiments, the reflux guide component can accelerate the blending rate of the energy storage fluid inside the energy storage steel tube and the energy storage fluid inside the elastic liquid storage bag while ensuring the expansion degree of the elastic liquid storage bag, so that the temperature of the energy storage fluid is more uniform, and further improves the cold and heat storage performance of the passing fluid.

[0012] Furthermore, the number of the first liquid guiding tubes, the elastic liquid storage bag, the guide plates and the guide ports is no less than ten, and the number ratio of the first liquid guiding tubes, the elastic liquid storage bag, the guide plates and the guide ports is one:one:two:one.

[0013] In one embodiment, this can diffuse the flow path of the fluid to ensure that the passing fluid can evenly cover the surface of the energy storage steel pipe.

[0014] Furthermore, the cross-sectional shape of the guide plate is wavy, and the end surface of the guide plate facing away from the elastic liquid storage bag is porous and rough.

[0015] In one embodiment, this can reduce the flow rate of the passing fluid, and the fluid momentum loss will further increase the heat, thereby allowing the heat of the hot fluid to be fully transferred to the thermal storage fluid.

[0016] Furthermore, a slide groove is provided at the opposite ends of the two circular frames, and a slider fixedly connected to the guide plate is slidably connected inside the slide groove. The vertical cross-section of the slide groove and the slider is an arc shape, and the center point of the cross-section of the slide groove and the slider coincides with the axis of the circular frame.

[0017] In one of the embodiments, this can effectively limit the guide plate to slide along the arc of the protection tank and the energy storage steel pipe.

[0018] Furthermore, a sealing ring is embedded and installed on the inner side of the reflux cylinder, and the sealing ring is sleeved on the surface of the output shaft of the electric cylinder.

[0019] In one embodiment, this can prevent the energy storage fluid from leaking between the return tube and the electric cylinder, so as to ensure the overall sealing of the conveying device.

[0020] Furthermore, the bidirectional infusion pump is fixedly connected to the first liquid guiding tube and is communicated with a liquid diversion valve.

[0021] In one embodiment, this enables the bidirectional infusion pump to uniformly deliver the storage fluid into the first catheter to ensure that each elastic reservoir can be uniformly expanded.

[0022] Furthermore, the monitoring system includes: a temperature monitoring module for real-time monitoring of the temperature of the passing fluid;

[0023] Flow monitoring module, used to monitor the flow of the passing fluid in real time;

[0024] The leakage monitoring module is used to monitor in real time whether the flow pressure of the passing fluid changes, so as to determine whether the protection tank and the energy storage steel pipe are leaking;

[0025] The water quality monitoring module is used to monitor the quality of the fluid passing through the water material in real time, so as to predict the degree of impurity accumulation inside the protective tank and facilitate timely maintenance;

[0026] The comprehensive system configuration module is used to comprehensively control the operation of electrical components and upload the monitoring data to the matching cloud database in real time.

[0027] In one embodiment, temperature monitoring, flow monitoring and pressure monitoring can cooperate with each other to adjust the cold and heat storage effect;

[0028] Furthermore, the protective tank and the energy storage steel pipe are 8 to 12 meters long. Multiple units can be combined by welding, plugging, and special connectors to extend infinitely to form a "pipeline" to achieve the "transportation" of the "energy storage medium". The inlet and outlet of the fluid guiding mechanism can be installed on the side of the protective tank as needed. It can be installed on each unit or at intervals.

[0029] The fluid guiding mechanism of the above-mentioned efficient intelligent cold and heat storage conveying equipment can not only automatically adjust the pressure and temperature of the passing fluid, so as to improve the conveying equipment's ability to efficiently and intelligently store cold and heat, but also solve the problem that the existing efficient intelligent cold and heat storage conveying equipment is prone to reduce the effective energy transfer rate due to changes in fluid flow;

[0030] The device can be buried directly underground, taking advantage of the natural constant ground temperature, with low heat loss, unaffected by ultraviolet rays from the sun, long life, and does not occupy ground space. Multiple monomers can be combined to form a pipeline without the need to build a special pipeline, thus achieving the purpose of "transporting" media and energy exchange, saving investment costs.

[0031] At the same time, an elastic liquid storage bag connected to the energy storage fluid is used, which can not only indirectly increase the contact area between the energy storage fluid and the passing fluid, further improve the cold and heat storage performance of the passing fluid, but also use the reflux guide component to accelerate the blending rate of the energy storage fluid inside the energy storage steel pipe and the energy storage fluid inside the elastic liquid storage bag under the premise of ensuring the expansion degree of the elastic liquid storage bag, so that the temperature of the energy storage fluid is more uniform, and the cold and heat storage performance of the passing fluid is further improved.

[0048] Combine the following Figure 1 - Figure 8 The invention describes the efficient and intelligent cold and heat storage and transportation equipment.

[0049] In one embodiment, a highly efficient and intelligent cold and heat storage and transportation equipment includes a protection tank 100 and a monitoring system 200. The monitoring system 200 is installed inside the protection tank 100. One end of the monitoring system 200 passes through the protection tank 100. The inside of the protection tank 100 is fixedly connected with an energy storage steel pipe 300. A fluid guiding mechanism 400 is installed on the surface of the protection tank 100. One end of the fluid guiding mechanism 400 passes through the protection tank 100 in sequence and extends to the inside of the energy storage steel pipe 300. The length of the protection tank 100 and the energy storage steel pipe 300 is 8 to 12 meters. Multiple monomers can be combined by welding, plugging, and special connectors to be infinitely extended to form a "pipeline" to achieve "transportation" of "energy storage medium". The inlet and outlet of the fluid guiding mechanism 400 can be installed on the side of the protection tank 100 as needed. It can be installed on each monomer or installed at intervals.

[0050] There is an insulation layer between the protection tank 100 (the material can be steel, or plastic, etc.) and the energy storage steel pipe 300 (the insulation material can be polyurethane rigid foam plastic, other insulation materials, or a composite of them). The protection tank 100 can be directly buried underground without occupying ground space to reduce heat loss, and the water temperature is higher than the normal pressure gasification temperature to store more thermal energy. The material of the energy storage steel pipe 300 can be a submerged arc butt-welded spiral steel pipe or a ductile iron pipe or a special alloy metal material. The diameter of the energy storage steel pipe 300 is DN2600 or more. When the storage medium of the energy storage steel pipe 300 is water, it can be pressurized and stored. The water temperature is higher than the normal pressure gasification temperature. The gaps at both ends of the energy storage steel pipe 300 and the protection tank 100 are sealed by special end seals. The inner wall of the protection tank 100 is provided with a polyurethane composite insulation layer. The thickness of the polyurethane composite insulation layer is five to ten centimeters. The thickness of the insulation layer is increased according to the insulation requirements. One end of the protection tank 100 is fixedly connected and connected to a fluid inlet pipe. and a heat storage fluid inlet pipe, the passing fluid inlet pipe and the heat storage fluid inlet pipe are respectively arranged on the outer side and the inner side of the energy storage steel pipe 300, one end of the passing fluid inlet pipe is fixedly connected and connected with a two-way water pump, one end of the two-way water pump is fixedly connected and connected with a heat exchanger, the other end of the protection tank 100 is fixedly connected and connected with a passing fluid outlet pipe and a heat storage fluid outlet pipe, the passing fluid outlet pipe and the heat storage fluid outlet pipe are respectively arranged on the outer side and the inner side of the energy storage steel pipe 300, the bottom of the protection tank 100 is fixedly connected and connected with a drain pipe, the drain pipe and the surface of the heat storage fluid outlet pipe are fixedly connected and connected with a solenoid valve, the device can be used individually or in series, the specific number of uses needs to be selected according to actual needs, which will not be elaborated here, and because the transported hot water can be combined with flash evaporation technology to achieve rapid steam transportation, so as to make up for the shortcomings of long-distance steam transportation pipelines with large heat loss, large safety hazards and high material requirements, and reduce the cost of steam use. In summary, this effectively solves the problem of inconsistency between heat supply and demand in time and space, improves the flexibility of thermal energy utilization, and also effectively solves energy management in the fields of renewable energy consumption, power system regulation and multi-energy complementarity;

[0051] After the passing fluid enters the interior of the protection tank 100 through the passing fluid inlet pipe, the passing fluid flows between the protection tank 100 and the energy storage steel pipe 300, and the passing fluid enters between two adjacent guide plates 440 along the guide port 452. During this process, if the heat of the passing fluid is high, the passing fluid will evenly transfer the heat to the energy storage steel pipe 300, and the energy storage steel pipe 300 will transfer the heat to the energy storage fluid to complete heat storage. Otherwise, the energy storage fluid will transfer the heat to the passing fluid through the energy storage steel pipe 300 to complete cold storage, and then the passing fluid will be discharged through the passing fluid outlet pipe.

[0052] like Figure 2 , Figure 3 , Figure 4, Figure 5 , Figure 6 and Figure 7 As shown, the fluid guiding mechanism 400 includes a two-way infusion pump 410 fixedly connected to the surface of the protection tank 100, one end of the two-way infusion pump 410 is connected to the energy storage steel pipe 300, one end of the two-way infusion pump 410 is fixedly connected and connected to a first liquid guide tube 420, one end of the first liquid guide tube 420 penetrates into the interior of the protection tank 100, the surface of the first liquid guide tube 420 is fixedly connected and connected to an elastic liquid storage capsule 430, and both ends of the elastic liquid storage capsule 430 are fixedly connected to the protection tank 100 and the energy storage steel pipe 300. The guide plate 440 is slidably connected to the tube 300, and the inlet and outlet of the guide plate 440 are staggered with the protection tank 100; the number of the first liquid guide tube 420, the elastic liquid storage capsule 430, the guide plate 440 and the guide port 452 is not less than ten, and the number ratio of the first liquid guide tube 420, the elastic liquid storage capsule 430, the guide plate 440 and the guide port 452 is one to one to two to one; the cross-sectional shape of the guide plate 440 is wavy, and the end surface of the guide plate 440 facing away from the elastic liquid storage capsule 430 is porous and rough;

[0053] The porous rough structure can reduce the flow rate of the passing fluid when the passing fluid enters the porous rough structure. According to the Bernoulli principle, the fluid momentum loss will further increase the heat, so that the heat of the porous rough fluid can be fully transferred to the surface of the energy storage steel pipe 300, so as to improve the fluid heat storage effect;

[0054] In the process of the passing fluid passing through the guide plate 440, the energy storage fluid inside the elastic liquid storage bag 430 exchanges heat with the passing fluid through the elastic liquid storage bag 430 and the guide plate 440, which can increase the indirect contact area between the energy storage fluid and the passing fluid to improve the overall cold and heat storage effect of the device.

[0055] like Figure 5 and Figure 6 As shown, the fluid guiding mechanism 400 also includes a positioning assembly 450, and the positioning assembly 450 also includes two circular frames 451, both of which are fixedly connected between the protection tank 100 and the energy storage steel pipe 300. The surface of the circular frame 451 is provided with a guide port 452, and the guide port 452 is arranged between two adjacent guide plates 440, and the guide port 452 is staggered with the first liquid guide tube 420 and the elastic liquid storage capsule 430; the opposite ends of the two circular frames 451 are provided with a slide groove 453, and the inside of the slide groove 453 is slidably connected with a slider 454 fixedly connected to the guide plate 440; the vertical cross-section shape of the slide groove 453 and the slider 454 is an arc shape, and the cross-section center point of the slide groove 453 and the slider 454 coincides with the axis line of the circular frame 451;

[0056] The two circular frames 451 can firmly confine the elastic liquid storage bag 430 and the guide plate 440 between the protection tank 100 and the energy storage steel pipe 300. At the same time, the slide groove 453 can also limit the guide plate 440 to slide along the arc between the protection tank 100 and the energy storage steel pipe 300 through the slider 454 to ensure that the distance between two adjacent guide plates 440 can be normally increased or reduced.

[0057] like Figure 3 , Figure 4 and Figure 7 As shown, the fluid guiding mechanism 400 also includes a reflux guiding assembly 460, which includes a reflux cylinder 461 fixedly connected to the inside of the protection tank 100, one end of the reflux cylinder 461 is connected to the energy storage steel pipe 300, and the surface of the reflux cylinder 461 is fixedly connected and connected to a second liquid guide tube 462 distributed in an annular shape, one end of the second liquid guide tube 462 sequentially penetrates the protection tank 100 and the adjacent round frame 451 and is fixedly connected and connected to the adjacent elastic liquid storage capsule 430, and the interior of the reflux cylinder 461 is slidably connected to a flow limiting disk 463 in contact with the second liquid guide tube 462, and the cross-sectional shape of the flow limiting disk 463 is a straight The shape of the angular trapezoid, the spacing between the top second liquid guide tube 462 and the flow limiting disk 463 is set to A, the spacing between the bottom second liquid guide tube 462 and the flow limiting disk 463 is set to B, the length ratio between A and B is 1:8, one end of the flow limiting disk 463 is fixedly connected to an electric cylinder 464, one end of the electric cylinder 464 passes through the reflux cylinder 461 and is fixedly connected to the protection tank 100; a sealing ring 465 is embedded and installed on the inner side of the reflux cylinder 461, and the sealing ring 465 is sleeved on the surface of the output shaft of the electric cylinder 464; the bidirectional infusion pump 410 is fixedly connected to the first liquid guide tube 420 and is connected to a liquid diverter valve 470;

[0058] When it is necessary to blend the energy storage fluid inside the energy storage steel pipe 300 with the energy storage fluid inside the elastic liquid storage capsule 430, the staff manually controls the electric cylinder 464 to shorten, and the electric cylinder 464 drives the flow limiting disk 463 away from the energy storage steel pipe 300. When the electric cylinder 464 shortens to the right position, the connection between the reflux tube 461 and the second liquid guide tube 462 is no longer blocked. At the same time, the staff manually controls the two-way infusion pump 410 to suck the energy storage fluid inside into the first liquid guide tube 420, and the energy storage fluid enters the elastic liquid storage capsule 430 through the first liquid guide tube 420. At this time, the original energy storage fluid inside the elastic liquid storage capsule 430 is squeezed into the second liquid guide tube 462, and the energy storage fluid enters the reflux tube 461 along the second liquid guide tube 462. The reflux tube 461 introduces the energy storage fluid into the energy storage steel pipe 300, so that the energy storage fluid blends together.

[0059] Since the blocking area of ​​the connection between the reflux cylinder 461 and the second liquid guide tube 462 by the flow limiting disk 463 gradually decreases from top to bottom, this can not only increase the flow resistance of the energy storage fluid inside the upper elastic liquid storage bag 430 to the energy storage steel pipe 300, but also reduce the flow resistance of the energy storage fluid inside the lower elastic liquid storage bag 430 to the energy storage steel pipe 300, so that the elastic liquid storage bag 430 always maintains the corresponding expansion force to limit the position of the guide plate 440, so as to ensure the flow pressure of the fluid passing through the guide plate 440.

[0060] like Figure 2 and Figure 8 As shown, the monitoring system 200 includes:

[0061] The temperature monitoring module 210 is used to monitor the temperature of the passing fluid in real time;

[0062] A flow monitoring module 220 is used to monitor the flow of the fluid passing through in real time;

[0063] The leakage monitoring module 230 is used to monitor in real time whether the flow pressure of the passing fluid changes, so as to determine whether the protection tank 100 and the energy storage steel pipe 300 have leakage;

[0064] The water quality monitoring module 240 is used to monitor the quality of the fluid passing through the water material in real time, so as to predict the degree of impurity accumulation inside the protection tank 100 and facilitate timely maintenance;

[0065] The integrated system configuration module 250 is used to comprehensively control the operation of electrical components and upload the monitoring data to a matching cloud database in real time.

[0066] Working principle: The flow monitoring module 220 monitors the flow pressure of the fluid in real time and transmits the monitoring data to the integrated system configuration module 250. The integrated system configuration module 250 compares the monitoring data with the preset data. When the difference between the monitoring data and the preset data exceeds the preset value, it indicates that the fluid passing pressure is too large or too small. At this time, the integrated system configuration module 250 controls the bidirectional infusion pump 410 according to the preset program to extract the thermal storage fluid inside the elastic liquid storage bag 430 through the first liquid guide tube 420 and transport it to the energy storage steel pipe 300. Inside, or correspondingly, the heat storage fluid inside the energy storage steel pipe 300 is extracted and transported to the inside of the elastic liquid storage bag 430 through the first liquid guide pipe 420. At this time, the elastic liquid storage bag 430 shrinks or expands accordingly, and the elastic liquid storage bag 430 synchronously drives the two guide plates 440 to move away or approach. At this time, the distance between the two adjacent guide plates 440 increases or decreases accordingly, which can effectively reduce or increase the fluid pressure between the protection tank 100 and the energy storage steel pipe 300, so as to ensure that the passing fluid can evenly transfer heat to the surface of the energy storage steel pipe 300.

[0067] It should be noted that the temperature monitoring module 210, flow monitoring module 220, leakage monitoring module 230, water quality monitoring module 240, integrated system configuration module 250, bidirectional infusion pump 410, electric cylinder 464 and liquid diverter valve 470 in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the temperature monitoring module 210, flow monitoring module 220, leakage monitoring module 230, water quality monitoring module 240, integrated system configuration module 250, bidirectional infusion pump 410 and electric cylinder 464 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0068] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
