Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a modular waste heat recovery performance detection device and method. Background Art

[0002] With the continuous growth of global energy demand and the increasing awareness of environmental protection, efficient energy utilization and energy conservation and emission reduction have become important issues in industrial production and sustainable development. In many industries such as steel, chemical, electric power, and building materials, a large amount of waste heat is directly discharged into the environment, which not only causes energy waste but also aggravates environmental pollution. Therefore, waste heat recovery technology has become a key means to improve energy utilization efficiency, reduce production costs, and reduce carbon emissions.

[0003] However, the performance of the waste heat recovery system directly affects the effect of energy recovery. In order to ensure the efficient operation of the waste heat recovery system, its performance needs to be accurately detected and evaluated. The traditional detection method mainly uses flow meters and thermometers to detect the flow and temperature of fluids, including liquids and gases, at both the inlet and outlet ends of the waste heat recovery system, and compare the inlet and outlet temperature differences to detect the waste heat recovery efficiency. However, due to the unstable fluid flow, that is, the fluid flow rate and pressure at the inlet and outlet positions are unstable, the flow meter cannot play the prerequisite of ensuring that the inlet and outlet flow rates are equal. On this basis, the detected temperature comparison and the calculated heat recovery rate are inaccurate, which results in the inability to accurately evaluate the waste heat recovery system.

[0045] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0046] like Figures 1 to 3 As shown, a modular waste heat recovery performance detection device of the present invention comprises:

[0047] A storage barrel 100, used for storing fluid;

[0048] The partition 101 is slidably disposed in the storage barrel 100 and is used to divide the interior of the storage barrel 100 into two chambers. The fluid enters the waste heat recovery system through one chamber and is discharged through the other chamber. When the partition 101 moves in the storage barrel 100, the sizes of the two chambers can be adjusted;

[0049] Two thermometers 102 are respectively disposed in the two chambers and are used to detect the temperature of the fluid in the two chambers;

[0050] Each chamber is connected with an input pipe 103 and an output pipe 104, and a constant pressure module 200 for adjusting the pressure balance of the two chambers is provided on the storage barrel 100;

[0051] The flow path of the fluid that needs to be recovered from waste heat in the present invention is that the fluid enters the chamber through the input pipe 103 on one chamber, and then flows into the waste heat recovery system through the output pipe 104 connected to the chamber for waste heat recovery. The fluid after waste heat recovery enters the corresponding chamber through the input pipe 103 connected to another chamber, and then is discharged through the corresponding output pipe 104.

[0052] In order to provide a stable environment for temperature detection and improve detection accuracy, the present invention adopts the following measures:

[0053] Pressure balance: the two chambers can achieve pressure balance through the constant pressure module 200;

[0054] Balance of the amount of substances. Since the temperatures of the fluids in the two chambers are different, when the fluid is gas, it is necessary to change the position of the partition 101 in the storage barrel 100 to make the volumes of the two chambers different, so that the mass of the gas in the two chambers can be consistent. When the fluid is liquid, it is only necessary to place the partition 101 in the middle of the storage barrel 100 to make the mass of the fluid stored in the two chambers consistent. Based on the temperature detection under the condition of consistent mass, the heat of the fluid before and after passing through the waste heat recovery system can be calculated, and the waste heat recovery rate can be calculated to realize the detection of waste heat recovery performance;

[0055] Since the fluid is always in a flowing state when passing through the storage barrel 100, the device can achieve a stable and dynamic detection effect on the fluid, and it is only necessary to keep the storage quality of the fluid in the two chambers consistent. At the same time, the storage barrel 100 can be used to achieve a temporary storage and buffering effect on the fluid, ensuring that the detection work can be carried out under relatively stable and equal quality conditions. In addition, since multiple parameters of the fluid entering and leaving the waste heat recovery system are equal, this method can simplify the calculation process and achieve a rapid detection effect.

[0056] Of course, in some cases, the fluid for waste heat recovery may also be plasma, supercritical fluid, non-flowing fluid, suspension, emulsion, etc.;

[0057] By setting up the constant pressure module 200, the pressure balance in the two chambers is ensured, thereby avoiding flow and temperature measurement errors caused by pressure fluctuations; by adjusting the position of the partition 101, the fluid quality in the two chambers is kept consistent, providing a stable basic condition for temperature detection; the device can perform real-time detection of the flowing fluid to ensure the accuracy and reliability of the detection results; the device is suitable for a variety of fluids and can meet the needs of different industrial scenarios; temperature detection is performed under conditions of consistent quality, which simplifies the heat calculation process and improves calculation efficiency.

[0058] During the process of fluid entering the chamber, the fluid entering the chamber will cause the chamber pressure to fluctuate due to the unstable fluid delivery. Although the constant pressure module 200 will keep the pressure of the two chambers balanced, this fluctuation will also cause the instantaneous change of the amount of fluid in the chamber. To reduce the impact of this fluctuation on the detection, the following method can be used: Figure 3 In the manner shown, the number of partitions 101 is set to two, and the space between the two partitions 101 is set to a buffer space. In this way, when the fluid enters the chamber, the fluctuating fluid will push the two partitions 101 to move relative to each other, and the two partitions 101 will squeeze the space between them. At this time, the compressed air in the buffer space is used to cache the partition 101 and the fluid in the chamber, thereby reducing fluctuations and improving detection accuracy.

[0059] Further, such as Figure 3 As shown, a transverse tube 105 is coaxially arranged on the storage barrel 100, and the transverse tube 105 passes through the storage barrel 100 and slides relatively, and the partition 101 is slidably installed on the transverse tube 105. A through hole is opened on the outer wall of the transverse tube 105 between the two partitions 101, and the through hole is connected to the outside through the transverse tube 105;

[0060] The outer wall of the transverse tube 105 between the two partitions 101 is connected to each partition 101 via a plurality of springs 107;

[0061] When the size of the two chambers needs to be adjusted, it can be achieved by pushing the cross tube 105 to move. When the partition 101 plays a caching role for the fluid in the space, the partition 101 slides on the cross tube 105 and uses the spring 107 to provide the partition 101 with reset and caching elastic force. The air between the two partitions 101 can enter and exit through the air holes 106 and the cross tube 105, so that the purpose of adjusting the size of the chamber is achieved and the caching effect is achieved; of course, the compressed air in the closed space between the two partitions 101 can also be used to cache the partition 101, but this method is not perfect, and there is a risk of air leakage, which affects the caching effect;

[0062] During the production process, one end of the storage barrel 100 is opened and a cover is installed. The partition 101 can be pre-assembled on the cross tube 105. Then the cross tube 105 is passed through the storage barrel 100, and the cover is replaced on the opening of the storage barrel 100. It has a simple structure and is easy to assemble.

[0063] As a preferred embodiment of the above, Figure 1 and Figure 3 As shown, the input pipe 103 is located at the bottom of the storage bucket 100, and the output pipe 104 is located at the top of the storage bucket 100;

[0064] A guide plate 108 is provided on the inner wall of each chamber in the storage barrel 100, the conical surface of the guide plate 108 faces downward, and the output end of the input pipe 103 on the storage barrel 100 faces the conical surface of the guide plate 108;

[0065] The fluid will enter the chamber through the input pipe 103. At this time, the fluid will start to fill the chamber from the bottom of the chamber, and the air in the original chamber will be pushed upward and enter the output pipe 104, thereby preventing air from remaining in the chamber and affecting the amount of fluid in the chamber. When the fluid is a gas, the gas will be blown onto the guide plate 108 and with the help of the guide plate 108, the gas will diffuse to the lower side of the interior of the chamber, so as to prevent the gas from directly gathering on the upper side of the interior of the chamber, and the air in the lower side of the original chamber cannot be discharged in time. When the fluid is a liquid, the air in the original chamber will be squeezed by the liquid and automatically discharged. Therefore, the above-mentioned structural method is mainly used for gas. Of course, the guide plate 108 can also have a buffering and diffusion effect on the liquid.

[0066] like Figures 4 to 5 As shown, the constant pressure module 200 includes:

[0067] Two wide channels 201 are respectively installed on the outer walls of the two output pipes 104, and the output pipes 104 are connected to the wide channels 201 thereon;

[0068] Two auxiliary pipes 202 are respectively connected and installed on the two wide channels 201;

[0069] The sealing column 203 is located between the two output tubes 104, and the end of the sealing column 203 is slidably inserted into the output tube 104 through the end of the output tube 104. The outer wall of the sealing column 203 is used to block the connection position between the wide channel 201 and the output tube 104, and adjust the blocking area;

[0070] Due to the use of the sealing column 203, the outer ends of the two output pipes 104 are horizontal and opposite to each other, and the shape of the output pipe 104 is right-angled or arched, so that a sealing column 203 can act on the two output pipes 104 at the same time; the fluid in the chamber can be discharged through the output pipe 104, the wide channel 201 and the auxiliary pipe 202, and the sealing column 203 can fully block, semi-block or fully open the connecting position between the wide channel 201 and the output pipe 104, so that the flow rate and pressure of the fluid discharged from the chamber can be adjusted by moving the position of the sealing column 203; in the natural state, the position of the sealing column 203 is not limited. When the fluid for pre-waste heat recovery enters the output pipe 104 through a chamber, the fluid will generate pressure on the end of the sealing column 203. At this time, the pressure The sealing column 203 will be pushed to move, and the wide channel 201 corresponding to the chamber is fully open to the connection position with the output pipe 104. The sealing column 203 completely blocks the wide channel 201 corresponding to the other chamber. When the fluid enters the other chamber after waste heat recovery, the fluid in the chamber will also enter the output pipe 104 and exert a force on the other end of the sealing column 203. As the amount of fluid in the chamber increases and the pressure increases, the sealing column 203 gradually moves in the opposite direction until the pressure at both ends of the sealing column 203 is balanced. At this time, the fluids in the two chambers can be normally transported through the two output pipes 104 respectively, and the fluid pressures in the two chambers are balanced through the sealing column 203, thereby achieving the effect of balanced pressure and ensuring the normal transportation of the fluid.

[0071] In the specific implementation process, the blocking area of ​​the wide channel 201 by the sealing column 203 in the equilibrium state can be set with reference to the type of fluid and the flow rate of the fluid in the natural state. Of course, it can also be set by a structure or method that can adjust the connecting diameter between the wide channel 201 and the output pipe 104, which are all within the protection scope of this case.

[0072] In order to facilitate the fluid in the output pipe 104 to smoothly generate thrust on the end of the sealing column 203, as shown in FIG. Figure 5 As shown, both ends of the sealing column 203 are arranged to be inclined surfaces 204 facing the storage barrel 100, so that even if the end of the sealing column 203 contacts the inner wall of the output tube 104, the fluid can still act on the inclined surface 204 and push the sealing column 203 to move.

[0073] For the control of detection timing, such as Figure 4 As shown, a slider 205 is provided on the outer wall of the sealing column 203, and the slider 205 is slidably installed on the outer wall of the storage barrel 100 along the moving direction of the sealing column 203;

[0074] A micro switch 206 is fixed on the storage barrel 100, and a detection head 207 is arranged on the micro switch 206. When the sealing column 203 moves, the sealing column 203 will drive the slider 205 to move synchronously, and the slider 205 can limit the sealing column 203 to prevent the sealing column 203 from rotating. When the side of the slider 205 moves to the position of the detection head 207, the detection head 207 contacts the side of the slider 205. At this time, the micro switch 206 detects the position of the slider 205, and the pressure in the two chambers is balanced, and the two thermometers 102 are controlled to perform temperature detection on the two chambers, thereby realizing automatic control of the temperature detection timing and avoiding the tedious operation of manually observing the position of the sealing column 203 and then performing temperature detection.

[0075] Further, such as Figure 4 As shown, the side wall of the slider 205 facing the detection head 207 is set to a trapezoidal or conical shape. The trapezoidal or conical setting can use the inclined surface of the corresponding shape to guide and transition the detection head 207, so as to avoid the slider 205 from colliding with the outer wall of the detection head 207 when moving; of course, in order to improve the tightness of the contact between the detection head 207 and the slider 205, the detection head 207 needs to be able to perform a small range of elastic movement on the micro switch 206; the purpose of setting the side wall of the slider 205 to a trapezoidal shape is to provide a larger contact area for the relative position of the slider 205 and the detection head 207, within which the pressures in the two chambers can be determined to be within the specified balance range, and the purpose of setting the side wall of the slider 205 to a cone is to reduce the contact area, thereby reducing the balance range and improving the detection accuracy;

[0076] In a specific implementation process, the side wall of the slider 205 can be set to be a trapezoid. The inclined surface of the trapezoid is not described in detail, and the plane width of the trapezoid can be changed and adjusted as needed.

[0077] To facilitate the use of the device, Figure 1 As shown, a handle 300 and a base 301 may be provided on the storage bucket 100. The handle 300 and the base 301 may be used to facilitate workers to hold and transfer the device, thereby improving the convenience of use.

[0078] Since the partition 101 and the cross tube 105 need to be adjusted in position, a power module needs to be provided, such as Figure 1 and Figure 2 As shown, an adjustment frame 400 is slidably provided on the outer wall of the storage barrel 100, the moving direction of the adjustment frame 400 is parallel to the moving direction of the transverse tube 105, the two ends of the adjustment frame 400 are connected to the two ends of the transverse tube 105, the side wall of the adjustment frame 400 is provided with teeth, and a micro motor 401 is provided on the outer wall of the storage barrel 100, and a gear 402 is provided at the output end of the micro motor 401, and the gear 402 is meshed with the teeth on the adjustment frame 400;

[0079] A shield 403 is provided on the outer side of the micro motor 401 and the gear 402, and the shield 403 is fixed on the storage barrel 100;

[0080] The micro motor 401 and the gear 402 can provide power for the movement of the adjustment frame 400, thereby adjusting the position of the partition 101 and the cross pipe 105. The shield 403 can shield the micro motor 401 and the gear 402 to prevent the running micro motor 401 and the gear 402 from causing harm to the workers.

[0081] A detection method of a modular waste heat recovery performance detection device of the present invention comprises the following steps:

[0082] Connect the two input pipes 103 and the two output pipes 104 on the storage bucket 100 to the pipeline;

[0083] The fluid enters a chamber in the storage barrel 100 and fills the chamber. Then, the fluid is discharged from the chamber to an external waste heat recovery system for waste heat recovery. The fluid after waste heat recovery enters another chamber in the storage barrel 100. When the fluid fills the chamber, the fluid is discharged again.

[0084] When the fluid is initially transported in the two chambers, the constant pressure module 200 will float. When the constant pressure module 200 is stable, the pressure in the two chambers reaches equilibrium.

[0085] Using two thermometers 102 to detect the temperature of the fluid in the two chambers;

[0086] According to the temperature of the fluid in the chamber and the temperature difference of the fluid in the two chambers, the position of the partition 101 in the storage barrel 100 is adjusted until the amount of the fluid in the two chambers reaches equilibrium;

[0087] When the amount of material in the two chambers is balanced, the temperature detected by the two thermometers 102 is recorded, and the temperature is used to calculate the heat change before and after the fluid passes through the waste heat recovery system and the waste heat recovery rate, thereby completing the detection of the performance of the waste heat recovery system.

[0088] The above are only preferred embodiments 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.
