[0027] 2. The jet tube of the present invention is evenly distributed with a plurality of micropores, and a main channel is opened in the middle of the jet tube. When the fluid in the inner tube passes through these micropores, a part of the fluid is introduced into the small holes. Due to the limitation of the aperture, the fluid velocity is significantly increased to form a high-kinetic energy jet, which is re-injected into the main fluid channel at high speed, producing a strong disturbance and mixing effect, which can not only increase the turbulence of the fluid, but also effectively break the boundary layer and reduce thermal resistance, thereby improving the heat transfer efficiency.

[0042] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8, an embodiment provided by the present invention: a high-pressure controllable temperature shell-and-tube heat exchanger with an embedded porous jet structure, comprising an outer tube 1, an inner tube 2 is sleeved inside the outer tube 1, a control box 22 is installed on the top of the outer tube 1, and the control box 22 is equipped with a control system, the control system comprises a microprocessor module, a monitoring module, a regulating module, an analysis and processing module and a safety protection module, the monitoring module uses a sensor to collect the temperature of the fluid in the inner tube 2, the pressure on the inner tube 2 and the flow condition of the inner tube 2 in real time, the analysis and processing module analyzes and processes the collected real-time data, the microprocessor module compares the real-time temperature data with the preset temperature, the control and regulation module regulates the heat exchange process, the regulation module uses a control valve to automatically regulate the flow of the fluid in the inner tube 2 to achieve temperature control, and the safety protection module uses an overpressure protection device to protect the safe operation of the heat exchanger;

[0043] The sensor includes a temperature sensor 18 embedded in the inner wall of the inner tube 2 and two groups of pressure sensors 17. The temperature sensor 18 is located between the two groups of pressure sensors 17. The two groups of pressure sensors 17 are respectively located at both ends of the inner tube 2. A differential pressure sensor 16 is installed at the bottom of the outer surface of the outer tube 1. The differential pressure sensor 16 is used to monitor whether the inner tube 2 is blocked.

[0044] Furthermore, the core of the shell-and-tube heat exchanger is a concentric shell-and-tube structure composed of an outer tube 1 and an inner tube 2. A medium circulates in the inner tube 2, which is the fluid to be exchanged, and another medium circulates in the outer tube 1. The medium is a hot fluid, which is mainly used to provide heat for heat exchange, so that the two fluid media can flow in an isolated environment and exchange heat through the tube wall. For better heat exchange, the outer tube 1 and the inner tube 2 are made of copper, titanium or cast iron with good thermal conductivity. The outer tube 1 is first fixed to the mounting frame by welding. Since the welding points are all on the surface of the outer tube 1, it will not affect the subsequent disassembly of the inner tube 2. Then the inner tube 2 is installed inside the outer tube 1 and fixed, and then the other pipelines are connected to the interface of the shell-and-tube heat exchanger in turn. After the installation is completed, the power is turned on to start the heat exchanger to start working;

[0045] A control box 22 is installed on the top of the outer tube 1 by welding. After the heat exchanger is powered on, the control box 22 automatically connects to the wireless communication network of the peripheral device. The maintenance manager sets the heat exchange temperature on the mobile phone APP, and the set temperature is sent to the microprocessor module of the control box 22 through the wireless communication network;

[0046] During the heat exchange process, the high-precision temperature sensor 18 monitors the temperature of the fluid flowing out of the inner tube 2 in real time, so as to automatically adjust the flow rate of the fluid medium in the inner tube 2 and the heat exchange intensity of the fluid flowing in the outer tube 1 according to the preset temperature adjustment control valve, thereby realizing precise temperature control. A pressure sensor 17 is installed at the inlet and outlet of the inner tube 2 to monitor the pressure state of the inner tube 2 when the fluid enters and leaves the inner tube 2. At the same time, by real-time monitoring of the pressure in the inner tube 2, it is easy to understand the operating status and timely discover the abnormality of the heat exchanger. The pressure sensor 17 is used in conjunction with the overpressure protector to ensure that the heat exchanger can be safely and stably operated under extreme conditions. During operation, the two input interfaces of the pressure difference sensor 16 are respectively connected to the inlet and outlet of the inner tube 2, so as to monitor whether the inner tube 2 is blocked. Once the pressure difference sensor 16 detects blockage, the microprocessor immediately generates an alarm signal and sends it to the monitoring end of the staff through the wireless communication network, prompting the staff to go to the site for maintenance and inspection in time. The analysis and processing module processes and analyzes the temperature and pressure data collected by the monitoring module, and then the microprocessor module determines whether the operation of the heat exchanger is abnormal according to the processed pressure data, so as to timely detect the abnormality of the heat exchanger, reduce the maintenance and repair rate, and thus improve the overall working efficiency of the equipment.

[0047] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 , an embodiment provided by the present invention: a high-pressure controllable temperature shell-and-tube heat exchanger with an embedded porous jet structure, a jet tube 15 is installed inside the inner tube 2, micropores 19 are evenly arranged inside the jet tube 15, a main channel is opened in the middle of the jet tube 15, and the main channel is located on the inner side of the micropores 19, a main channel is opened in the middle of the jet tube 15, and the main channel is located on the inner side of the micropores 19, one end of the inner tube 2 is an inner tube inlet 10, and a flange 4 is installed at one end of the inner tube inlet 10;

[0048] An outer tube inlet pipe 5 is installed at the top of the outer tube 1, and an outer tube outlet pipe 6 is installed at the bottom of the outer tube 1. The opening ends of the outer tube outlet pipe 6 and the outer tube inlet pipe 5 are both installed with flange 20;

[0049] The other end of the inner tube 2 is an inner tube outlet 11 , which is located behind the hexagonal side plate 7 , and the inner wall of the inner tube outlet 11 is provided with threads.

[0050] Furthermore, a jet tube 15 is welded inside the inner tube 2. The jet tube 15 is made of a material with good thermal conductivity and excellent corrosion resistance, such as stainless steel. A plurality of micropores 19 are evenly distributed on the jet tube 15, and a main channel is opened in the middle of the jet tube 15. When the fluid in the inner tube 2 passes through these micropores 19, a part of the fluid is introduced into the small holes. Due to the limitation of the aperture, the fluid velocity is significantly increased to form a high-kinetic energy jet, which is re-injected into the main fluid channel at high speed, producing a strong disturbance and mixing effect, which can not only increase the turbulence of the fluid, but also effectively break the boundary layer and reduce thermal resistance, thereby improving the heat transfer efficiency. At the same time, the high-speed fluid takes away the sediment and impurities on the tube wall, has a certain self-cleaning function, and reduces the maintenance cost and maintenance frequency. The inner tube inlet 10 is the fluid inlet port. A flange 4 is installed at the port 10 by welding, an outer tube inlet pipe 5 is welded to the top of the outer tube 1, a flange 20 is welded to the top of the outer tube inlet pipe 5, an outer tube outlet pipe 6 is welded to the bottom of the outer tube 1, and a flange 20 is welded to the port of the outer tube outlet pipe 6. The input pipe of the hot fluid is fixed to the flange 20 at the outer tube inlet pipe 5 by bolts, and the output pipe of the hot fluid is fixed to the flange 20 at the outer tube outlet pipe 6 by bolts. The input pipeline of the fluid to be heated is fixed to the flange 4 by bolts, and it is ensured that the filter device 12 is fixed between the flange 4 and the input pipeline of the fluid to be heated, so as to filter the fluid in advance and remove impurities such as scale therein. A thread is arranged inside the inner tube outlet 11 for installing the fixed fluid output pipeline to avoid fluid leakage caused by unstable connection, thereby affecting the heat exchange efficiency.

[0051] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 An embodiment of the present invention is: a high-pressure temperature-controllable shell-and-tube heat exchanger with an embedded porous jet structure, wherein a filter device 12 is installed at one end of the flange 14, and a differential pressure sensor 23 is installed at the bottom of the outer tube 1. The differential pressure sensor 23 is used to monitor the blockage of the filter device 12, and the differential pressure sensor 23 is electrically connected to the microprocessor module.

[0052] Furthermore, when connecting flange 4 and the fluid input pipeline, the filter device 12 is placed between the two and fixed by bolts. After fixing, the middle part of the filter device 12 is embedded in the inner tube inlet 10 and the input pipeline to avoid leakage. Since the filter device 12 is easy to disassemble, different filter devices 12 can be replaced according to the specific situation of the heat exchanger in actual use. The scale inhibitor filter is mainly used. The food-grade rich phosphate is wrapped by the filter membrane. When the fluid flows through, it reacts with the calcium and magnesium particles therein to form a soluble complex, thereby avoiding the formation of insoluble substances such as calcium carbonate and magnesium carbonate. Since the filter membrane has a smaller mesh, it can pass through the material. The large particles of impurities and particles in the fluid are intercepted and effectively prevented from adhering to scale and other sediments, which greatly reduces the maintenance frequency and cleaning cost. The two input ends of the differential pressure sensor 23 are respectively connected to the inlet and outlet of the filter device 12. By monitoring the pressure difference between the input and output ends of the filter device 12, it is determined whether the filter device 12 is blocked by impurities. Once the filter device 12 is blocked, the microprocessor module will send relevant information to the staff, prompting the staff to replace the clean filter device 12 as soon as possible, and clean the blocked filter device 12 to avoid affecting the normal filtering effect of the filter device 12 and the flow rate of the fluid.

[0053] See also Figure 3 and Figure 5 An embodiment of the present invention is a high-pressure temperature-controllable shell-and-tube heat exchanger with an embedded porous jet structure, wherein an open groove 29 is provided at one end of the outer tube 1, a pressure sensor 13 is installed on the inner wall of the open groove 29, a positioning side plate 3 is installed on the outer surface of the inner tube 2, and the positioning side plate 3 is embedded in the open groove 29, and an open groove 8 is provided at the other end of the outer tube 1, a hexagonal side plate 7 is installed on the outer surface of the inner tube 2 through threaded embedding, and the hexagonal side plate 7 is threadedly embedded in the open groove 18.

[0054] Furthermore, when installing the outer tube 1 and the inner tube 2, first connect the data line installed on the outer tube 1 to a voltage of 5V to power only the pressure sensor 13, and when the installation is completed, disconnect the data line from the 5V voltage to avoid damage to the equipment caused by the heat exchanger running at an excessively low voltage when using the heat exchanger for heat exchange. The inner tube 2 is embedded in the outer tube 1 and pushed into the outer tube 1 until the pressure sensor 13 detects the pressure, then the push is stopped. At this time, the hexagonal side plate 7 is put on the inner tube 2 from the inner tube outlet 11, and is threadedly engaged between the outer tube 1 and the inner tube 2, and the hexagonal side plate 7 is tightened. This installation method is easy to disassemble and helps to facilitate maintenance and cleaning.

[0056] A spiral guide vane 14 is installed inside the outer tube 1 , and the spiral guide vane 14 is located outside the inner tube 2 , and the spiral guide vane 14 is located in front of the sealing gasket 21 .

[0057] Furthermore, the sealing gasket 21 is fixed in the outer tube 1, which increases the sealing between the outer tube 1 and the inner tube 2, preventing the fluid in the outer tube 1 from flowing out from the gap between the outer tube 1 and the inner tube 2, thereby affecting the heat exchange efficiency. The spiral guide vane 14 is welded to the inside of the outer tube 1. Since the spiral guide vane 14 is spiral, it effectively extends the running trajectory of the fluid in the outer tube 1, increases the contact time between the fluid and the inner tube 2, and thus improves the heat exchange efficiency.

[0058] Furthermore, the method for using the high-pressure temperature-controllable shell-and-tube heat exchanger comprises the following steps:

[0059] Step S1, sleeve the inner tube 2 into the outer tube 1, and fix it with the hexagonal side plate 7, and then install the outer tube 1 and the inner tube 2 in the waiting position;

[0060] Step S2, first filter the fluid to be heated by the filter device 12, then let the fluid flow into the inner tube 2 from the inner tube inlet 10, and at the same time let the hot fluid flow into the outer tube inlet 5 to perform a heat exchange process, so as to heat the fluid to be heated in the inner tube 2;

[0061] Step S3: During the heat exchange process, the monitoring module monitors the heat exchange process of the shell-and-tube heat exchanger in real time;

[0062] Step S4, finally the heated fluid flows out from the outer tube outlet pipe 6, and the heated fluid flows out from the inner tube outlet 11;

[0063] In step S3, the following steps are also included:

[0064] Step S31 , real-time monitoring of the temperature of the fluid flowing out of the inner tube outlet 11 , and temperature control by automatically adjusting the flow rate of the fluid in the inner tube 2 .

[0065] Working principle: First, fix the outer tube 1 on the mounting frame by welding, then connect the data line installed on the outer tube 1 to the voltage of 5V, only power the pressure sensor 13, and then push the inner tube 2 into the outer tube 1 until the pressure sensor 13 detects the pressure, then stop pushing it forward, at this time, put the hexagonal side plate 7 on the inner tube 2 from the inner tube outlet 11, and insert it between the outer tube 1 and the inner tube 2 through the thread, and tighten the hexagonal side plate 7, and then connect other pipelines to the interface of the shell and tube heat exchanger in turn. After the installation is completed, turn on the power to start the heat exchanger to start working;

[0066] During the heat exchange process, the high-precision temperature sensor 18 monitors the temperature of the fluid flowing out of the inner tube 2 in real time, the pressure sensor 17 monitors the pressure state of the inner tube 2 when the fluid enters and leaves the inner tube 2, and the pressure difference sensor 16 monitors whether the inner tube 2 is blocked. Once the pressure difference sensor 16 detects blockage, the microprocessor immediately generates an alarm signal and sends it to the monitoring end of the staff through the wireless communication network, prompting the staff to go to the site for maintenance and inspection in time.
