Description

Technical Field

[0001] The present invention relates to the technical field related to heat exchange equipment, and in particular to a plate and shell type heat exchange equipment. Background Art

[0002] As a key device for achieving heat transfer, heat exchange equipment plays an extremely important role in many fields such as industrial production, energy utilization and daily life. Whether it is the heating or cooling of reaction materials in chemical production, the heating and cooling of indoor air in the HVAC system, or the recovery and utilization of waste heat in power equipment, it is inseparable from the efficient operation of heat exchange equipment. Shell and tube heat exchanger is one of the more common types of heat exchange equipment. Its interior is composed of a tube bundle and an outer shell. Heat exchange is achieved through the temperature difference between the fluid inside and outside the tube bundle. The emergence of plate heat exchanger has solved the problem of heat transfer efficiency to a certain extent. It is composed of a series of corrugated metal plates stacked together to form narrow and tortuous fluid channels between adjacent plates. With the rapid development of modern industry towards high efficiency, energy saving and compactness, as well as the continuous improvement of equipment reliability and stability requirements, the current heat exchange equipment can no longer fully meet the needs of actual production and life. Therefore, a plate and shell heat exchange equipment is particularly needed.

[0003] However, the existing plate and shell heat exchange equipment is not designed with a vibration device. In terms of heat transfer efficiency, when the fluid flows between the heat exchange plates, a boundary layer is easily formed near the surface of the plate. The fluid flow rate in the boundary layer is low and the heat transfer resistance is large. Without a vibration device, the boundary layer is difficult to be effectively disturbed, and heat transfer mainly relies on heat conduction, which is inefficient. For fluids with high viscosity or low flow rate, the boundary layer has a more significant impact, which greatly limits the improvement of the overall heat transfer coefficient. It is difficult to use the impact force and high-frequency oscillation generated by vibration to prevent dirt from adhering to and accumulating on the surface of the heat exchange plate. At the same time, no cleaning device is designed. During the heat exchange process, the impurities, minerals, microorganisms and other substances contained in the fluid will gradually deposit on the surface of the heat exchange plate. As the operating time increases, the deposits continue to accumulate to form a dirt layer. The thermal conductivity of the dirt is much lower than that of the metal heat exchange plate, which greatly increases the thermal resistance and seriously hinders heat transfer, resulting in a significant decrease in heat exchange efficiency and more energy consumption for heating or cooling the fluid, resulting in a large amount of energy waste. Summary of the invention

[0004] The object of the present invention is to provide a plate and shell heat exchange device to solve the problem that the existing plate and shell heat exchange device proposed in the above background technology is not designed with a vibration device. In terms of heat transfer efficiency, when the fluid flows between the heat exchange plates, a boundary layer is easily formed near the surface of the plate. The fluid flow rate in the boundary layer is low and the heat transfer resistance is large. If there is no vibration device, the boundary layer is difficult to be effectively disturbed, and the heat transfer mainly relies on heat conduction, which is inefficient. For fluids with high viscosity or low flow rate, the boundary layer has a more significant impact, which greatly limits the improvement of the overall heat transfer coefficient. It is difficult to use the impact force and high-frequency oscillation generated by vibration to prevent dirt from adhering to and accumulating on the surface of the heat exchange plate. At the same time, no cleaning device is designed. During the heat exchange process, the impurities, minerals, microorganisms and other substances contained in the fluid will gradually deposit on the surface of the heat exchange plate. As the running time increases, the sediments continue to accumulate to form a dirt layer. The thermal conductivity of the dirt is much lower than that of the metal heat exchange plate, which greatly increases the thermal resistance and seriously hinders the heat transfer, resulting in a significant decrease in heat exchange efficiency, consuming more energy for heating or cooling the fluid, and causing a large amount of energy waste.

[0048] Working principle: When in use, the staff will first check the environment around the entire device and the status of its various parts. If there is a problem, the entire device will be repaired or replaced in time. After the inspection, the staff will first place the support frame 1 on a flat ground to ensure its levelness and stability, providing a solid foundation for subsequent installation. The shell 2 is fixedly installed on the top of the support frame 1, and tightened with suitable bolts and nuts to ensure a firm connection. The shell-side fluid inlet 3, shell-side fluid outlet 4, plate-side fluid outlet 7 and plate-side fluid inlet 8 are installed at the corresponding positions of the shell 2. During the installation process, attention should be paid to the sealing treatment. Sealing gaskets can be used to prevent leakage. Install sealing port 1 5 and sealing port 2 6 to ensure that their size and structure are symmetrical and the installation position is accurate to ensure sealing performance , install the vibration component 9 inside the shell 2, first fix the spring seat 907 and the mounting base 912 at the corresponding positions of the inner wall of the shell 2 respectively, put the multi-plate body 901 on the vibration rod 905 through the limiting hole 904, ensure that the plates are arranged neatly, install the telescopic spring 909 on the spring seat 907, then connect the spring pad 910 with the telescopic spring 909, and make the limiting column 908 pass through the through hole 2 911 and the limiting groove 906, install the electric cylinder 913 on the mounting base 912, connect the telescopic rod 914 with the vibration rod 905, install the cleaning component 10 on the inner wall of the shell 2, fix the motor 1001, connect the rotating rod 1002 with the output end of the motor 1001, install the cleaning brush 1003 on the outside of the rotating rod 1002, and Install the sliding block 1004 at one end of the rotating rod 1002, fix the slide rail 1006 on the inner wall of the shell 2, make the sliding block 1004 and the slide rail 1006 slidably connected, check whether the installation of each component is firm, the connection is correct, and the sealing is good, turn on the power, start the electric cylinder 913, observe the vibration of the vibration rod 905, adjust the parameters of the electric cylinder 913, ensure that the vibration frequency and amplitude meet the design requirements, start the motor 1001, check the rotation of the rotating rod 1002 and the cleaning brush 1003, ensure that they can smoothly perform circular cleaning motion, respectively introduce an appropriate amount of fluid into the shell side fluid inlet 3 and the plate side fluid inlet 8, observe the flow of the fluid and the heat exchange effect, adjust the inlet and outlet flow and temperature, so that the equipment can achieve optimal operation state, according to the set parameters and procedures, hot fluid and cold fluid are continuously introduced into the shell-side fluid inlet 3 and the plate-side fluid inlet 8 to carry out the heat exchange process. The electric cylinder 913 of the vibration component 9 works according to the set frequency and amplitude, driving the vibration rod 905 to vibrate, thereby vibrating the plate body 901, disturbing the fluid, improving the heat transfer efficiency and reducing the dirt deposition. The motor 1001 of the cleaning component 10 is started regularly to drive the rotating rod 1002 and the cleaning brush 1003 to do a circular cleaning motion to remove the dirt on the surface of the plate body 901. During the operation of the equipment, the temperature, pressure, flow rate and other parameters of the inlet and outlet fluids, as well as the vibration and cleaning conditions of the equipment are monitored in real time to ensure the normal operation of the equipment. The hot fluid enters the shell 2 from the shell-side fluid inlet 3,The cold fluid enters the channel between the plate body 901 from the plate side fluid inlet 8, and the hot fluid and the cold fluid flow on both sides of the plate body 901, and heat is exchanged through the plate. The concave-convex texture 902 on the outer side of the plate body 901 increases the contact area between the fluid and the plate. At the same time, the vibration component 9 causes the fluid to generate strong disturbances, breaking the laminar flow and forming turbulence, which enhances the mixing and collision between fluid molecules and accelerates the heat transfer speed. The hot fluid after heat exchange flows out from the shell side fluid outlet 4, and the cold fluid flows out from the plate side fluid outlet 7. After the electric cylinder 913 is energized, its active end drives the telescopic rod 914 to reciprocate, and the telescopic rod 914 and the vibration rod 905 The plate body 901 is fixedly connected so that the vibration rod 905 reciprocates in the limiting hole 904 of the plate body 901. The vibration of the vibration rod 905 is limited by the cooperation of the limiting column 908 and the limiting groove 906 to ensure the stability and accuracy of the vibration. The telescopic spring 909 plays a role of buffering and energy storage during the vibration process. When the vibration rod 905 moves to one side, the telescopic spring 909 is compressed to store energy. When the vibration rod 905 moves in the opposite direction, the telescopic spring 909 releases energy to reduce the impact of vibration on the equipment structure. At the same time, the continuity and stability of the vibration are ensured. The plate body 901 vibrates synchronously with the vibration of the vibration rod 905, which has an impact on the shell and The plate fluid is disturbed to improve the heat transfer efficiency and reduce the dirt deposition. After the motor 1001 is started, its output end drives the rotating rod 1002 to rotate. The sliding block 1004 at one end of the rotating rod 1002 is slidably connected with the sliding rail 1006 on the inner wall of the shell 2 through the sliding groove 1005. Since the sliding rail 1006 is a circular ring structure, the sliding block 1004 moves in a circular motion along the sliding rail 1006, thereby driving the rotating rod 1002 and the cleaning brush 1003 to do a circular cleaning motion. The cleaning brush 1003 contacts the surface of the plate body 901 during the rotation process to remove the dirt on the surface of the plate to ensure that the plate always maintains good heat transfer performance. Two sets of cleaning brushes 1003, sliding block 1004 and slide slot 1005 are symmetrically distributed about the vertical center line of rotating rod 1002, making the cleaning process more uniform and comprehensive. Finally, the staff regularly checks the wear of various components, such as vibration rod 905, cleaning brush 1003, etc. If there is wear, replace them in time, check the sealing performance of sealing components, such as sealing port 15, sealing port 26, etc. If there is leakage, repair or replace the sealing gasket in time, regularly clean the dirt and impurities inside the equipment to ensure the smooth flow of fluid channels, and regularly maintain and service electrical equipment such as electric cylinder 913 and motor 1001, check their electrical and mechanical properties, and ensure their normal operation.

[0049] The above shows and describes the basic principles, main features and advantages of the present invention. 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.
