Description

Technical Field

[0001] The present invention relates to the technical field of polyester production, and specifically to a green energy-saving and consumption-reducing device applied to the production process of polyester polyol. Background Art

[0002] Polyester polyol is one of the main raw materials for synthesizing polyurethane. It is prepared by polycondensation of dibasic organic carboxylic acid, carboxylic anhydride, low molecular weight ester or semi-ester with diol. According to whether the polyester polyol molecular chain contains a benzene ring, it can be divided into two categories: aliphatic polyol and aromatic polyol. Aliphatic polyester polyol is a milky white solid or colorless to light yellow viscous liquid at room temperature. The melting point of solid polyester polyol is relatively low, generally between 25°C and 50°C, and it becomes a viscous liquid after melting. Aliphatic polyester polyols are slightly soluble in water, and the acid value is generally lower than 1.0mgKOH / g. Aromatic polyester polyol is a light yellow to brownish red viscous transparent liquid, with relatively stable chemical properties, generally with a slight aromatic odor, non-toxic, non-corrosive, good compatibility with the vast majority of organic substances, and belongs to non-flammable and non-explosive products. So far, the technology of polyester polyol in China has developed rapidly, but most of them are intermittent production lines and use the batch method for production.

[0003] However, in the prior art, during the operation of the traditional polyester production process, the reaction requires a relatively high temperature (above 220 degrees) and a relatively long reaction time (above 20 hours). As a result, most domestic enterprises have to adopt coal, gas or electric (electromagnetic) heating technologies and use independent reaction kettles for batch production, leading to low production efficiency and high energy consumption. Therefore, it is necessary to propose a green energy-saving and consumption-reducing device applied to the production process of polyester polyol. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] In the present invention, with the cooperation of the heat collection following assembly, the spherical concentrating glass is used to cause the light to refract when passing through the lens, so as to converge to the focal point position. Then, the light intensity, angle, position and pressure signals in the system are collected in real time by the sensor group, and the signals collected by the sensor group are processed by the built-in prediction controller to generate control instructions, so that the control instructions are sequentially transmitted to the driving angle control motor, the driving pulley structure, the angle control brushless motor, the rotating gear driving structure and the azimuth angle gear driving structure through the signal line, so as to form a closed-loop control operation as a whole. And the position of the sun is detected by the light sensor, and the altitude angle and azimuth angle of the sun are calculated in combination with the geographical location, date and time. Then, the built-in prediction controller generates control instructions according to the sun position time control algorithm to ensure that the system can track the sun position in real time, so that an accurate sun position time control algorithm can be used to ensure that the whole can accurately track the sun day by day, realizing the maximum collection of sunlight. Under the data feedback of the sensor group, the driving angle control motor is started according to the angle and azimuth of the sun rays, so that the driving angle control motor drives the output pulley structure to rotate, and the rotational motion is transmitted to the rotating shaft disc track through a belt or a chain, and the rotating shaft disc track drives the L-side frame to rotate, so as to realize the angle adjustment of the condenser lens in the horizontal direction. Secondly, the driving pulley structure drives the rotating screw rod column to rotate through a belt or a chain, and the rotation of the rotating screw rod column causes the sliding seat to move along its axis, and drives the condenser lens to adjust the angle in the vertical direction through the rotating force bearing hinge and the synchronous hinge, thereby accurately controlling the position of the condenser lens, realizing the effective real-time tracking and focusing of sunlight, improving the heat energy collection efficiency, effectively improving the production efficiency and reducing the energy consumption.

[0019] 2. In the present invention, with the cooperation of the dynamic homology component and the homology heat collection component, the angle-controlled brushless motor drives the rotating gear to rotate through its output end, achieving precise angle control. Then, the rotation of the rotating gear is transmitted to the outer gear ring through meshing with the outer gear ring, realizing the transmission of the angle to the homology heat collection component, facilitating the dynamic following of the heat collection following component's light concentration operation for reflection by the homology heat collection component. The outer gear ring forms a rotational connection on the inner bottom surface of the installation housing through the rotating ring at the bottom, ensuring the stable rotation of the outer gear ring. At the same time, when the above-mentioned outer gear ring rotates, the installation fixing frame and the structures it carries are driven by the rotating gear drive structure to perform angular adjustment in the horizontal direction, ensuring that the reflector can perform horizontal tracking following the above-mentioned condenser operation. Then, the reflector is driven by the azimuth angle gear drive structure to perform angular adjustment in the vertical direction, ensuring that the reflector can perform vertical tracking according to the elevation angle of the condenser. Through the combined adjustment in the horizontal and vertical directions, full-angle azimuth tracking of the reflector to the condenser is achieved, ensuring the maximized reflection adjustment operation during light collection.

[0020] 3. In the present invention, with the cooperation of the variable control component, when the analog energy storage tank inside the heat storage tank stores different forms of thermal energy through the phase change energy storage tank, the solid energy storage tank, and the chemical energy storage tank respectively, the delivery port in the variable control component draws the thermal energy from the analog energy storage tank. After the three groups of multi-temperature section output structures divide the thermal energy into low-temperature section, medium-temperature section, and high-temperature section respectively to output thermal energy in different temperature sections according to the needs of different users, the output controller controls the distribution of the thermal energy according to the actual needs, and converges the thermal energy in different temperature sections to the microcapsule encapsulation structure through the connecting pipe. The microcapsule encapsulation structure outputs the encapsulated thermal energy to the steam generator through the output valve pipe, so as to deliver the thermal energy to the user operation pipeline or the feed water pump delivery pipeline. When the phase change energy storage tank operates, the microcapsule encapsulation structure is used to encapsulate molten salt through microcapsules, increasing the surface area of the phase change material, accelerating the heat exchange rate, and at the same time solving the problem of molten salt corrosion, improving the stability and safety of the overall long-term operation. The solid energy storage tank uses shape memory alloy as the energy storage medium, and uses the thermal-mechanical conversion characteristics to store a large amount of energy in a smaller volume, and at the same time has good cycle stability. Secondly, the chemical energy storage tank uses nanostructured magnesium-based materials to enhance the adsorption and release rate of hydrogen, shorten the energy storage-discharge cycle, and improve the energy conversion efficiency.

According to the above operations, heat energy is transferred to the heat collection and transmission pipeline 11 through the heat-conducting oil and then transported to the heat storage tank 10. The heat storage tank 10 stores the heat energy transported by the heat collection and transmission pipeline 11. And the circulation pump 12 is started according to the instruction of the central processing controller, and the heat-conducting oil in the heat storage tank 10 is transported to the steam generator 14 through the first heat-conducting oil circulation pipeline 13, facilitating the steam generator 14 to generate steam using the heat energy in the heat-conducting oil, and enabling the generated steam to be distributed to the user operation pipeline or the water supply pump delivery pipeline through the output valve pipeline 15. And the heat-conducting oil discharged from the steam generator 14 returns to the heat storage tank 10 through the second heat-conducting oil circulation pipeline 16 to complete a cycle.

When the phase change energy storage tank is operating, the microcapsule encapsulation structure 234 is used to encapsulate molten salt with microcapsules, increase the surface area of the phase change material, accelerate the heat exchange rate, and at the same time solve the problem of molten salt corrosion, improving the stability and safety of the overall long-term operation. The solid energy storage tank uses shape memory alloy as the energy storage medium, and uses the thermal-mechanical energy conversion characteristics to store a large amount of energy in a smaller volume, and at the same time has good cycle stability. Secondly, the chemical energy storage tank uses nanostructured magnesium-based materials to enhance the hydrogen adsorption and release rate, shorten the energy storage-discharge cycle, and improve the energy conversion efficiency.

Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the heat transfer oil centralized heat energy receiver 4, the variable frequency pump 6, the heat energy appropriate distributor 8, the steam generator 14, and the sensor group will not be explained in detail.

[0045] Usage method and working principle of this device: Firstly, when conducting the production operation of polyester polyol, the polysphere glass 1 is used to cause the light to refract when passing through the lens, so as to converge to the focal position. Then, the sensor group is used to collect the light intensity, angle, position and pressure signals in the system in real time, and the signals collected by the sensor group are processed by the built-in predictive controller to generate control instructions, so that the control instructions are sequentially transmitted to the drive angle control motor 191, the drive pulley structure 197, the angle control brushless motor 171, the rotating gear drive structure 181 and the azimuth angle gear drive structure 183 through the signal line, so as to form a closed-loop control operation as a whole. And the position of the sun is detected by the optical sensor, and the altitude angle and azimuth angle of the sun are calculated in combination with the geographical location, date and time. Then, the built-in predictive controller generates control instructions according to the time control algorithm of the sun position, ensuring that the system can track the sun position in real time, so that it can ensure that the whole can accurately track the sun day by day under the precise time control algorithm of the sun position, realizing the maximization of sunlight collection. Under the data feedback of the sensor group, the drive angle control motor 191 is started according to the angle and azimuth of the sun rays, so that the drive angle control motor 191 drives the output pulley structure 192 to rotate, and the rotational motion is transmitted to the rotating shaft disc track 193 through a belt or a chain, and the rotating shaft disc track 193 drives the L-side frame 194 to rotate, so as to realize the angle adjustment of the condenser lens 199 in the horizontal direction. Secondly, the drive pulley structure 197 drives the rotating lead screw column 195 to rotate through a belt or a chain, and the rotation of the rotating lead screw column 195 causes the sliding seat 196 to move along its axis, and drives the condenser lens 199 to adjust the angle in the vertical direction through the rotating force-bearing hinge 198 and the synchronous hinge 1990, so as to accurately control the position of the condenser lens 199, realize the effective tracking and focusing of sunlight, and improve the heat energy collection efficiency. Then, synchronously, the angle control brushless motor 171 drives the rotating gear 170 to rotate through its output end to realize precise angle control. Then, the rotation of the rotating gear 170 is transmitted to the outer gear ring 172 through the meshing with the outer gear ring 172, realizing the angle transmission to the same concentration heat collection component 18, so that the same concentration heat collection component 18 can reflect dynamically following the condensing operation of the heat collection following component 19. And the outer gear ring 172 forms a rotational connection on the inner bottom surface of the installation shell 2 through the rotating ring at the bottom, ensuring that the outer gear ring 172 can rotate smoothly. At the same time, when the above-mentioned outer gear ring 172 rotates, the installation fixing frame 180 and the structures it carries are driven by the rotating gear drive structure 181 to adjust the angle in the horizontal direction, ensuring that the reflector 184 can follow the operation of the above-mentioned condenser lens 199 for horizontal tracking. Then, the reflector 184 is driven by the azimuth angle gear drive structure 183 to adjust the angle in the vertical direction, ensuring that the reflector 184 can track in the vertical direction according to the altitude angle of the condenser lens 199. Through the combined adjustment in the horizontal direction and the vertical direction, the reflector 184 realizes the full-angle azimuth tracking of the condenser lens 199.Ensure the maximized reflection adjustment operation during light collection. When the sunlight collected is introduced through the opening of the vacuum tube type heat collection channel 3, after being refracted by the angular heat collection prism 21, it irradiates the absorption coating on the inner wall. Among them, two groups of angular fine-tuning cylinders 20 can adjust the position of the angular heat collection prism 21, so as to collect light more effectively. Then the absorption coating absorbs the light energy and converts it into heat energy, enabling the heat energy to be transferred to the heat transfer oil through the heat transfer oil centralized heat receiver 4. The heat transfer oil is guided to the heat energy appropriate distributor 8 through the three-way valve 7, and then distributed to different usage points according to requirements. Furthermore, through the three-way valve 7 according to the instructions of the central processing controller, the flow direction of the heat transfer oil is controlled to reasonably distribute the heat energy to different application scenarios. Then the heat energy appropriate distributor 8 distributes the heat energy according to the actual demand and transfers it to the processing cabinet structure 5. Among them, the heat transfer oil centralized heat receiver 4 transfers the heat energy to the variable frequency pump 6. The variable frequency pump 6 adjusts the flow rate and pressure of the heat transfer oil according to the instructions of the central processing controller, and based on the above operations, enables the heat energy to be transferred to the heat collection and transportation pipeline 11 through the heat transfer oil and transported to the heat storage tank 10. The heat storage tank 10 stores the heat energy transported by the heat collection and transportation pipeline 11, and the circulation pump 12 is started according to the instructions of the central processing controller to transport the heat transfer oil in the heat storage tank 10 to the steam generator 14 through the first heat transfer oil circulation pipeline 13, facilitating the steam generator 14 to generate steam using the heat energy in the heat transfer oil, and enabling the generated steam to be distributed to the user operation pipeline or the feed water pump delivery pipeline through the output valve pipeline 15. Among them, the heat transfer oil discharged from the steam generator 14 returns to the heat storage tank 10 through the second heat transfer oil circulation pipeline 16 to complete a cycle. Among them, when different forms of heat energy are respectively stored in the analog energy storage tank 22 inside the heat storage tank 10 through the phase change energy storage tank, the solid energy storage tank, and the chemical energy storage tank, the delivery port 231 in the variable control component 23 draws out the heat energy from the analog energy storage tank 22, and the three groups of multi-temperature section output structures 232 respectively divide the heat energy into low-temperature section, medium-temperature section, and high-temperature section to output heat energy in different temperature sections according to the needs of different users. The output controller 236 controls the distribution of the heat energy according to the actual demand, and converges the heat energy in different temperature sections to the microcapsule encapsulation structure 234 through the connecting pipe 233. The microcapsule encapsulation structure 234 outputs the encapsulated heat energy to the steam generator 14 through the output valve pipe 235, enabling the heat energy to be transported to the user operation pipeline or the feed water pump delivery pipeline. Among them, during the operation of the phase change energy storage tank, the microcapsule encapsulation structure 234 is used to encapsulate molten salt with microcapsules, increasing the surface area of the phase change material, accelerating the heat exchange rate, while solving the problem of molten salt corrosion and improving the overall long-term operation stability and safety. The solid energy storage tank uses shape memory alloy as the energy storage medium, and utilizes the thermal-mechanical conversion characteristics to enable a large amount of energy to be stored in a smaller volume, and at the same time has good cycle stability. Secondly, the chemical energy storage tank uses nanostructured magnesium-based materials to enhance the hydrogen adsorption and release rate and shorten the energy storage-discharge cycle.Improve energy conversion efficiency.
