Description

Temperature control system

Technical Field

The invention relates to a temperature control system, in particular to a temperature control system for a waste material separation system of a gas-solid system or a liquid-solid system.

Background

When the surface coating of the waste metal is removed, organic compounds on the surface of the waste metal are decomposed by heat, and dust formed by part of the organic compounds after cracking and other finely divided materials is removed by gas-solid system or liquid-solid system separation equipment such as a cyclone separator. Since a part of organic compounds contained in dust is flammable, high concentration of dust is liable to cause combustion and even dust fire when the dust is discharged. Conventional fire extinguishing means make it difficult to control such fires caused by the burning of dust. Secondly, if water is added to the dust to form a slurry mixture in order to reduce the probability of fire, the cost of separation disposal will be increased and new safety or environmental issues may be introduced as a result.

CN110892221A discloses a cyclone temperature control system for a cyclone of a de-coating system comprising a controller, a gas mover and a control valve movable between a fully open position and a closed position. A method of controlling the temperature of a cyclone includes determining a cyclone temperature of the cyclone and comparing the cyclone temperature to a cyclone threshold temperature. The method also includes opening a temperature control valve and directing at least some heating steam from an afterburner of the decoating system to mix with exhaust gas from a kiln of the decoating system to increase a temperature of the exhaust gas if the cyclone temperature is below the cyclone threshold temperature.

However, with respect to the theoretical knowledge of the temperature control of the gas-solid system or liquid-solid system separation equipment/system including the multiple disciplines of chemical, physical, electrical, electronic, mechanical and instrumentation automation, in order to maintain the efficient and stable operation of the equipment/system, the operator of the plant considers more how to know one or more uncertain factors which may exist and/or already exist but are not yet established due to the hysteresis of data acquisition, transmission and processing to optimize the operation environment of the equipment/system and to plan or deploy the operation condition of the equipment/system based on the one or more uncertain factors, so as to enable the monitoring, management and debugging of the equipment/system to be highly automated while minimizing the influence caused by human error, thereby increasing the useful life of the device/system. Secondly, although there are many schemes for monitoring the real-time operation status of the device/system by means of simulation in the prior art, however, there is a limitation in reviewing and predicting the operation condition of the equipment/system by such a stereoscopic model image with synchronous updating capability generated from an external simulation thereof according to the connection manner, structural features and operation state of the equipment/system, for example, when the real-time running state of the equipment and the future running state of the equipment are estimated by checking the state parameter table corresponding to each equipment in the stereo model image, the real-time state parameter table of the equipment is inaccurate, and the change state inside the equipment cannot be reflected timely and effectively due to large errors caused by the hysteresis of data, differences existing in the data and the like, so that the potential fault risk of the equipment or the system cannot be predicted effectively and accurately. Thus, there remains a need in the art for at least one or several aspects of improvement.

Furthermore, on the one hand, due to the differences in understanding to the person skilled in the art; on the other hand, as the inventor studies a lot of documents and patents while making the present invention, but the space is not detailed to list all the details and contents, however, this invention doesn't have these prior art features, but this invention has all the features of the prior art, and the applicant reserves the right to add related prior art in the background art.

Detailed Description

The following detailed description is made with reference to fig. 1 and 2.

The present invention relates to a temperature control system, in particular for separating gaseous and solid or mixed liquid and solid waste. Specifically, the present invention illustrates a scrap separation system 10 for separating and recycling scrap metal, which may include one of the following components: a heater 102, a waste separating device 104, an incinerating device 106, a heat exchanging device 107, a plurality of gas circulation pipes provided between the respective devices for communicating with each other, and other several devices such as a pump, a motor, a fan, or a blower, which are shown or not shown.

According to a preferred embodiment, the unseparated scrap 101 formed of the metal scrap having the organic coating layer may be fed into the combustion chamber inside the heater 102 through the scrap inlet 114 of the heater 102 to be subjected to high-temperature calcination. During the entire heating process, some of the heating steam may be fed into the combustion chamber of the heater 102 through the air inlet 116 located on the heater 102, thereby increasing the temperature in the combustion chamber and further accelerating the calcination of the unseparated waste material. When the temperature of the combustion chamber in the heater 102 reaches a certain temperature, the organic coating on the scrap metal is continuously heated due to the high temperature, and thus the peeling phenomenon occurs, and thus the separation process of the organic coating from the scrap metal is completed, it is noted that the high temperature steam supplied from the outside and the oxygen content in the heater 102 need to be maintained at a low level to prevent the oxide generated by the combustion from accelerating the combustion of the scrap metal itself.

According to a preferred embodiment, after the above-mentioned process of separating the organic coating from the metal scrap, the scrap outlet 115 on the heater 102 can convey the separated scrap 103 to the outside of the apparatus, so that the separated scrap 103 can be processed into new metal products for recycling and avoiding unnecessary waste.

According to a preferred embodiment, when a portion of the non-separated metal scrap is recycled and calcined in the heater 102 after the metal scrap and the organic coating are separated, a large amount of low temperature air entering the combustion chamber of the heater 102 through the air inlet 116 of the heater 102 cools the high temperature steam in the heater 102, and under the effect of this temperature difference, a portion of the organic coating that has not been separated or separated but has not yet been removed from the heater 102 is re-condensed and stays in the heater to be recycled and undergoes a process of being melted to be re-condensed.

According to a preferred embodiment, the high temperature steam that is used for high temperature calcination of the non-separated waste 101 in the heater 102, after heat exchange with the non-separated waste, forms waste steam containing a portion of organic matter steam and/or particulate matter, which leaves the heater 102 through the air outlet 117 of the heater 102 and enters the first passage 100 a. Further, the waste steam containing partially vaporized organics and/or particulates enters the waste separation device 104 via the first channel 100a to further remove particulates from the waste steam and exit the waste separation device 104. Preferably, the waste separation device 104 may be a cyclone or other device capable of gas-solid/liquid-solid system separation.

According to a preferred embodiment, the waste steam primarily separated by the waste separation device 104 enters the incineration device 106 through the first channel 100a to further incinerate residual organic matters in the waste steam by the incineration device 106. The incinerated heating exhaust steam is discharged to the gas polymerization device 108 or the atmosphere through the second passage 100b or the third passage 100 c. The temperature of the heating steam treated by the incineration device 106 in the second channel 100b is higher than the temperature of the exhaust steam containing partially evaporated organic matter and/or particulate matter discharged from the heater 102.

According to a preferred embodiment, the incineration means 106 may comprise an air incinerator 111 or the like for gas heating. Preferably, part of the heating exhaust steam discharged from the incineration apparatus 106 may be recycled and injected into the heater 102 through the fourth passage 100d again. Optionally, a cooling device (not shown), such as one or a combination of air cooling and water cooling devices, may be provided on the circulation gas path of the heating exhaust steam entering the heater 102 through the fourth passage 100d to reduce the temperature of the heating exhaust steam discharged from the incineration device 106 when it again enters the heater 102.

According to a preferred embodiment, a second air pressurization device 105 (e.g., fan, blower) may optionally be provided between the incineration device 106 and the waste separation device 104 to provide the power to feed the waste steam into the incineration device 106. Further, a heat exchanging device 107 may be provided between the incineration device 106 and the gas polymerization device 108 to lower the temperature of the heated exhaust steam discharged from the incineration device 106 when it enters the gas polymerization device 108.

Preferably, at least a portion of the cooled gas discharged from the heat exchanging device 107 may be re-circulated into the heater 102 through a third air pressurizing device 109 located on the sixth passage 100 f. Further, at least another part of the cooled gas discharged from the heat exchanging device 107 may be re-circulated and injected into the incineration device 106 through the fourth air pressurization device 110 located on the fifth passage 100e to control the temperature of the incineration device 106 when treating a large amount of organic matter remaining in the exhaust steam to avoid overheating thereof, and simultaneously control the gas atmosphere inside the incineration device 106. Optionally, a fifth air pressurizing means 112 and a sixth air pressurizing means 113 may be additionally provided to supply oxygen into the incineration device 106 to help burn residual organics in the waste steam and to simultaneously control the gaseous atmosphere in the incineration device 106.

In accordance with a preferred embodiment, to maintain the stability of the entire waste separation system 10, the waste separation system 10 includes a temperature control system 20 for controlling the waste separation device 104. Further, the temperature control system 20 may include a first exhaust gas pressurization device 201, a regulator valve 202, a temperature control device 203, and a regulator passage 204. Specifically, one end of the regulating passage 204 communicates with the second passage 100b, and the connection point with the second passage 100b is located between the incineration device 106 and the connection point where the second passage 100b is connected with the fourth passage 100 d. The other end of the conditioning passage 204 communicates with the first passage 100a, and its connection with the first passage 100a is located between the waste separator 104 and the air outlet 117 of the heater 102. The first exhaust gas pressurizing means 201 and the regulating valve 202 are provided on the regulating passage 204 in this order in the discharge direction of the heating steam. The temperature control device 203 may be electrically and/or communicatively coupled to the first exhaust pressurization device 201, the regulating valve 202, and at least one temperature sensor (not shown) for detecting a temperature of the waste separation device 104. For example, a temperature sensor may be provided at the inlet of the waste separation device 104, at a location between the waste separation device 104 and the connection of the conditioning channel 204 and the first channel 100a, or at another location that facilitates sensing the temperature of the waste separation device 104. Preferably, the temperature control device 203 can control the temperature of the waste separation device 104 by adjusting the operation state of other devices or equipment based on the detection result of the temperature sensor, so that the real-time operation temperature of the waste separation device 104 can be maintained in a state higher than or equal to the standard operation temperature.

According to a preferred embodiment, the first exhaust gas pressurization device 201 is capable of providing power to direct or propel the flow of gas. Specifically, the first exhaust gas pressurizing device 201 is configured to be used at a high temperature, for example, when the gas heated by the incinerator 106 enters the regulating passage 204, the temperature of the gas is as high as thousands of degrees celsius, and the amount of the gas flowing into the regulating passage 204 and the first passage 100a through the second passage 100b is limited by controlling the opening and closing of the regulating valve 202 and the corresponding opening and closing degree thereof. Preferably, the first exhaust gas pressurizing means 201 may be a fan, a blower or other devices for propelling the gas flow, which can withstand high temperatures.

In a waste separation system 10 without a temperature control system 20, according to a preferred embodiment, the temperature of the waste separation device 104 is generally determined by the temperature of the spent steam in the first channel 100 a. If the temperature of the waste material separating apparatus 104 is to be raised, it is a common practice to raise the calcining temperature of the heater 102 to raise the temperature of the exhaust steam discharged from the heater 102, thereby raising the temperature of the waste material separating apparatus 104, but the heater 102 in a high-temperature operating state for a long time may generate a risk of smoke generation or cause damage to the heater 102. Based on conventional wisdom, it is generally believed that lower temperatures are beneficial in reducing the probability of a dust fire, but conversely, the higher temperatures reflected by the experiments can reduce or prevent the occurrence of a dust fire because raising the temperature of the waste separation device 104 removes more organics from the dust, so that the amount of organics in the dust emitted to the atmosphere is reduced, thereby reducing the probability of dust burning.

According to a preferred embodiment, when the temperature control device 203 determines that the real-time operating temperature of the waste separation device 104 is lower than the standard operating temperature based on the detection result of the temperature sensor, the temperature control device 203 controls the regulating valve 202 to be in a partially opened or fully opened state, and activates the first exhaust gas pressurizing device 201. Preferably, the degree of opening and closing of the regulating valve 202 may be determined by the difference between the real-time operating temperature of the waste separation device 104 and the standard operating temperature, the expected rate of temperature rise of the waste separation device 104, and the like. Further, the temperature control device 203 drives the first exhaust gas pressurization device 201 to guide or advance at least a portion of the heating steam discharged from the incineration device 106 into the regulation channel 204, and finally into the first channel 100a to be mixed with a portion of the exhaust steam discharged from the heater 102 in the first channel 100 a.

According to a preferred embodiment, when the temperature control device 203 determines that the real-time operating temperature of the waste separation device 104 is higher than or equal to the standard operating temperature based on the detection result of the temperature sensor, the temperature control device 203 detects the opening and closing degree of the regulating valve 202 and controls the regulating valve 202 to be in a closed state, and simultaneously closes the first waste gas pressurizing device 201 to prevent at least part of the heating steam discharged from the incineration device 106 from entering the regulating channel 204.

According to a preferred embodiment, the temperature control system 20 can control the operation temperature of the waste material separating system 10 or the waste material separating device 104 to reduce the occurrence probability of dust fire and improve the dust separating effect, and the dust separating effect of the waste material separating system 10 and the safe and stable operation thereof will depend on whether the devices in the waste material separating system 10 or the temperature control system 20 can stably and effectively maintain reasonable operation state. Therefore, in order to monitor the real-time operation state of the waste material separating system 10 or the temperature control system 20 to optimize the operation condition thereof, thereby maintaining the stable operation of the waste material separating system 10 or the temperature control system 20, the present invention supervises and manages the waste material separating system 10 or the temperature control system 20 through a real-time visualization method. In particular, the method is implemented by a control system of the waste separation system 10 or the temperature control system 20. Further, the control system at least comprises a control unit 100, an acting device 200, a first graphics processor 300, a second graphics processor 400, a graphics conversion unit 500, an operation unit 600 and a monitoring device 700, as shown in fig. 2. The control unit 100 is used to adjust the operating state of the reaction device 200. Preferably, the functional units are connected to each other by means of electrical and/or wired/wireless communication coupling.

According to a preferred embodiment, the monitoring device 700 comprises several sensors arranged in the waste separation system 10 or the temperature control system 20. Specifically, in addition to the aforementioned at least one temperature sensor for detecting the real-time operating temperature of the waste separation device 104, the monitoring device 700 includes several other sensors capable of detecting and acquiring one or more parameters including, but not limited to, the operating temperature of the equipment, pressure, flow rate of the fluid, content of certain organic matter in the dust, displacement of the motor shaft/pump link, and rotational speed of the fan or blower. Further, the plurality of sensors included in the monitoring apparatus 700 are configured with unique device numbers, so that when the waste separation system 10 or the temperature control system 20 is monitored and managed, the sensors can be located to the corresponding devices or corresponding components in the devices through the unique device numbers of the sensors.

According to a preferred embodiment, the control unit 100 may include one or a combination of a dedicated chip, an MCU, a CPU, a cloud server. The control unit 100 is capable of controlling the start-stop of each of the influencing devices 200 and/or adjusting their operating power etc. on the basis of the detection or acquisition data of the monitoring device 700.

According to a preferred embodiment, the action means 200 comprises various devices included in the waste material separating system 10 or the temperature control system 20 of the present embodiment, such as the waste material separating device 104, the incineration device 106 or a plurality of air movers (105, 109, 110, 112, 113) and the like shown in fig. 1, and a plurality of devices such as pumps, motors, fans or blowers and the like which are not shown. Further, at least one other part of the sensors included in the monitoring device 700, in addition to at least one part of the sensors for detecting temperature, pressure, flow, degree of opening and closing of the valve, and a certain organic matter mass fraction, is disposed inside each of the devices in the waste separation system 10 or the temperature control system 20. In particular, at least part of the sensors located inside each device are arranged correspondingly on the acting means inside the device, such as for example the blades of an air impeller, such as a fan or blower, the impeller inside the pump device, the valve stem inside part of a control valve, the drive shaft of an electric motor or the crankshaft of an engine, a connecting rod, etc. I.e. a component whose spatial position changes relatively as a function of time during operation of the apparatus, can be defined as the active device.

According to a preferred embodiment, an attitude sensor can be arranged, for example, on at least one blade or vane (105, 109, 110, 112, 113) of the air impeller for measuring the operating state thereof. Or the attitude sensor is arranged on a driving shaft of the motor or a crankshaft and a connecting rod of the engine and is used for measuring the motion state of the motor. On the other hand, a plurality of temperature sensor gaps can be arranged on at least one fan blade or blade of the air impeller (105, 109, 110, 112, 113) for measuring the temperature of the air impeller, so as to further represent the temperature gradient change of the air impeller (105, 109, 110, 112, 113) in various places through a stereo model image simulation mode, thereby facilitating the manager to judge the operation state of the equipment through images.

According to a preferred embodiment, the control unit 100 is capable of driving the first graphic processor 300 to perform a planar image flow simulation of the real-time operation state of the apparatus based on the real-time detection and collection data of the apparatus internal action device, and controlling the second graphic processor 400 to perform a stereoscopic model image simulation of the motion state change of the apparatus internal action device based on the detection and collection data of the apparatus internal action device in combination with the planar image flow simulation image of the first graphic processor 300. Further, the simulation images output by the first graphic processor 300 and the second graphic processor 400 can be displayed on the operation unit 600, so that the manager can check the current operation status of each action device 200 in time. Preferably, the operation unit 600 may be an operation display device, such as a computer, a tablet computer, etc., disposed in a factory building.

Preferably, in the case where the operation device is constituted by a hand-held portable terminal device having a display portion, the planar image output from the first graphic processor 300 and the stereoscopic model image output from the second graphic processor 400 are alternatively displayed on the operation device in a time-sharing manner, wherein the action units selected on the planar or stereoscopic model image are displayed in a manner corresponding to at least one known exterior component of the temperature control system. Since the temperature control system is prone to inaccurate temperature measurement caused by the fact that condensed steam is solidified into an organic coating to cover the conveying channel, the channel is often provided with a plurality of detachable air pressurizing devices, and if only the parts related to faults are displayed on a plane and three-dimensional model image, a maintenance worker cannot accurately find the access channel and even cannot understand the specific direction of the access channel. Under the condition that a field maintenance worker only holds a small display screen, the plane or three-dimensional model picture is displayed in a time-sharing alternative mode, the display area can be only enlarged, and the maintenance worker cannot be assisted to accurately find a passage entering a fault part. The invention therefore provides that the detection unit 700 provided on the operating device within the temperature control system is stored in a manner correlated with the component whose detachment is dependent, so that the operating device, which is displayed alternatively on the operating device in a time-shared manner, will also correlate with the structural component displayed in relation thereto, in particular at least one component whose detachment is dependent, in particular at least one component whose detachment is visible on the outer surface. For example, when the fourth air pressurizing device 110 located inside the conveying channel is stored as the second air pressurizing set in combination with the third air pressurizing device 109 and the channel connecting the two, that is, the third and fourth air pressurizing devices and the connecting channel of the two together constitute the second air pressurizing set; said second air pressurization assembly is located inside the surface not visible, distinct from the fifth air pressurization device 112 and the sixth air pressurization device 113 located in the outer region of the channel, but in an upstream-downstream relationship with said first air pressurization assembly constituted by the fifth air pressurization device 112 and the sixth air pressurization device 113 located in the outer region of the channel. When the second air pressurization assembly located inside has excessive pressure due to blockage transmission, the control unit indicates that the second air pressurization assembly is in an abnormal working state based on a blockage signal given by the sudden increase of the motor current, and the action devices (the third air pressurization device 109 and the fourth air pressurization device 110, namely the first air pressurization assembly) displayed on the operation device are highlighted (for example, in red) alternatively in a time-sharing manner, wherein the fact that the first air pressurization assembly is displayed in red on the operation device in a kit manner sometimes does not allow a maintenance worker to understand the problem faced by the first air pressurization assembly, especially the position of a fault object to be eliminated. To this end, the invention provides that the selected effect device (component or kit to be debugged) on the planar or volumetric model image is displayed in a manner corresponding to at least one known appearance component of the temperature control system, which appearance component is located outside the temperature control system in a macroscopic manner, wherein preferably said appearance component is formed by components located in at least two positions of the surface cleaning device "radially opposite" the selected effect device, whereby when the effect device displayed on the operating device is selected in a time-shared manner, the operating device will poll at least two volumetric model images different from each other in a time-shared manner, including not only the selected effect device, at least one component in a dependent relationship with its removal, but also at least one appearance component located outside the temperature control system in a macroscopic manner, the stereo model images are at least images of two visual angles different from each other, so that maintenance personnel can accurately find out the fault part and the fault kit and jointly determine the disassembly passage and the approach mode of the fault part and the fault kit according to the displayed plane images.

According to a preferred embodiment, the functional means inside each process tool in the waste separation system 10 or the temperature control system 20 of the present embodiment are given a uniform code set according to a preset definition rule. Preferably, each code corresponds to a unique component, and the unified code may correspond to a device number of the sensor provided on the corresponding component. When the real-time dynamic simulation of the temperature control system is performed by the first graphic processor 300 and the second graphic processor 400, the corresponding codes of the acting devices are called to at least obtain the planar image/stereoscopic model image graphic components of the corresponding acting devices for further simulation imaging. On the other hand, the planar image/stereo model image graphic component of the corresponding action device can be obtained by transferring the device number of the sensor corresponding to the action device in the form of a lookup table for further use in the simulation imaging. Preferably, the codes called by the first graphics processor 300 and the second graphics processor 400 are unique and identical.

Preferably, when the first graphic processor 300 and the second graphic processor 400 are used to perform real-time dynamic simulation on the waste separation system 10 or the temperature control system 20, only codes related to the action devices inside the equipment and/or equipment numbers of sensors corresponding to the action devices need to be called, and data searching, analysis screening and matching are not needed, so that a great deal of operation time is saved. Secondly, if the real-time running state information of different devices is required to be obtained by checking the real-time dynamic images simulated by the first graphic processor 300 and the second graphic processor 400, besides directly clicking the corresponding devices in the planar image flow image and/or the stereo model image, the codes of the acting devices or the device numbers of the sensors corresponding to the acting devices can be called in a lookup table mode to position the relevant devices, so as to further check the real-time running state of the acting devices in the devices.

According to a preferred embodiment, the first graphic processor 300 can simulate the real-time status of each device under the temperature control system by means of plane image simulation, i.e. can combine the graphic components corresponding to the devices with the attribute data for display. For example, the first graphic processor 300 can display the operation status of the waste separation system 10 and the respective effect devices 200 under the temperature control system 20 in the form of, for example, a PID or PFD flow chart based on the connection schematic of the waste separation system 10 and the temperature control system 20 shown in fig. 1. When the corresponding equipment in the plane image is clicked, various operating parameters of the equipment in the current state, including but not limited to operating temperature, pressure or flow and the like, are displayed. Further, the first graphic processor 300 stores graphic or digital information related to the serial numbers, structural compositions, design parameters, functions, and the like of the respective devices in the waste material separating system 10 or the temperature control system 20 in advance. Preferably, the first graphic processor 300 is capable of displaying parameters of all variables related to the operation state of each equipment in the waste material separation system 10 or the temperature control system 20 and attribute information thereof, and driving the corresponding alarm module to inform the manager of the possible unexpected risk condition in the current state in an acoustic/optical manner when the control unit 100 detects that the equipment-related parameters are higher or lower than the standard threshold.

According to a preferred embodiment, the second graphic processor 400 is capable of displaying real-time motion state changes of the working devices within the simulation and simultaneous update apparatus based on data detected and collected by sensors corresponding to the respective working devices disposed within the working device 200. Preferably, the change in motion state comprises at least a change in mechanical motion of the action means and a change in temperature gradient. The mechanical motion variation is configured as a stereo model image output by the second graphic processor 400 with respect to the real-time rotation state of the effect device inside the apparatus. Preferably, the stereoscopic model image can be displayed by means of picture frequency stream. For example, the description will be made by taking the air movers (105, 109, 110, 112, 113) as examples. When the output power of (105, 109, 110, 112, 113) of the air mover is adjusted by the control unit 100 to change the rotation speed of its fan blade or vane, the control unit 100 can synchronously drive the second graphic processor 400 to adapt to the change in the rotation speed of the fan blade or vane so as to synchronously simulate a moving image showing its increased or decreased rotation. For the temperature gradient change, the temperature values of the points can be collected or detected by a plurality of temperature sensors disposed on the blades or vanes (105, 109, 110, 112, 113) of the air impeller, and the temperatures of the points of the blades or vanes can be indicated by various representations such as different colors, grayscales and patterns. Preferably, each temperature change value can be associated with a different characterization to build a relational database to enable the temperature change of the device to have a characterization form corresponding thereto.

Preferably, there is a certain hysteresis in the transmission and analysis of data, and a parameter such as a rotation speed at a certain time interval is characterized by an average value in the time period, so that the current operation state of the device is judged only by looking at a dynamic change value of a relevant parameter of the device, and the output power of the device is adjusted to be relatively lagged and have a certain error based on the parameter of the current operation state, so that the simulation of the change state of an internal action device of the device by the second graphic processor 400 in real time enables a manager to know the operation state of the device in time according to the current motion state of the action device, so that the control unit 100 and/or the manager can judge the expected risk that the device may exist based on the current motion state of the action device. For example, when each power parameter is fixed, the rotation speed of the blades or vanes of the air impeller (105, 109, 110, 112, 113) tends to be stable under ideal conditions, and different setting parameters correspond to a plurality of different rotation states and corresponding standard rotation images, and the standard rotation images are stored in a database of the system. Preferably, the standard rotation image of the blades or vanes of the air mover (105, 109, 110, 112, 113) is represented by the same rotation speed of any point on a circle formed by the centrifugal rotation of points on the edges of the blades or vanes. For example, each dot's rotational speed may be characterized by a different color, sharpness or brightness, etc., and thus the color of each dot having the same rotational speed may be the same.

Further, when the rotation speed of the fan blade or the vane deviates from the standard rotation speed, for example, the rotation speed of the fan blade or the vane is gradually reduced due to the deposition of too much dust on the fan blade or the vane, or the rotation speed of the fan blade or the vane is indirectly affected by the slight damage of other components for indirectly driving the rotation of the fan blade or the vane of the first exhaust gas pressurizing device 201 due to the long-term high temperature caused by the heated steam discharged from the burning device 106, at this time, the real-time rotation image of the fan blade or the vane is different from the standard rotation image. For example, a real-time rotation image of a fan blade or a blade shows that a circle formed by centrifugally rotating points on the edge of the fan blade or the blade shows a state in which the colors of the points along the circumferential direction of the circle are different or continuously changed in a three-dimensional model image. Specifically, through the simulated image constructed by intuitive color change, the change trend of the rotation of the fan blades or vanes of the air impeller (105, 109, 110, 112, 113) can be reflected on the basis of the rotation of the fan blades or vanes, so that a manager can know the current operation state of the equipment in time. Next, the control unit 100 can acquire the dynamic simulation image of the internal action device of the device uploaded by the second graphic processor 400 in real time, compare the dynamic simulation image with the standard rotation image preset in the database, and feed back the analysis result to the administrator through the operation unit 600 to prompt the administrator to make device adjustment and optimization in advance.

According to a preferred embodiment, the graphical conversion unit 500 stores graphical data relating to the design layout of the waste separation system 10 or the temperature control system 20, the mechanical and/or electrical connections of the systems or devices to each other, and the plant structural layout. Further, the graphic conversion unit 500 can combine the attribute information of the device with the graphic data to drive the second graphic processor 400 to output a stereoscopic model image corresponding to the planar image in synchronization. For example, the graphic conversion unit 500 can simulate the connection layout of the trash separation system 10 or the temperature control system 20 with a planar image or a stereoscopic image in proportion to the physical devices. Next, based on the attitude sensors installed on the internal operation devices of each device, on the basis that the internal structural features of each device are displayed through the second graphic processor 400, the control unit 100 drives the second graphic processor 400 to simulate the motion state change of the operation device in combination with the stored data of the graphic conversion unit 500, and outputs a certain proportion of a stereoscopic model image to the operation unit 600 so that the manager can at least determine the current operation state of the device. The attribute information of the device includes a device model, a specification and a size, a material and a structure, a spatial position, and the like. Furthermore, the attribute information of the device also includes operation condition information and warning information of the device. Preferably, the warning information is warning information or status information when the device reaches a warning threshold.

According to a preferred embodiment, the plane image output by the first graphic processor 300 is correlated with the stereoscopic model image output by the second graphic processor 400, so that when the manager clicks on the device or action means included in one of the plane image and/or the stereoscopic model image, the manager can simultaneously locate or mark the corresponding device or action means in the other. Specifically, when the manager clicks a certain device in the plane image, the second graphic processor 400 can display a stereoscopic model image corresponding to the device according to a preset correspondence rule in response to the clicking operation. Furthermore, when a certain device in the plane image is clicked, a parameter table related to the operation state of the device is synchronously displayed, and the parameter table includes, in addition to the parameters of the whole device, such as the operation temperature, the operation pressure, the operation flow rate, and the like, unified codes corresponding to each action device in the device and device numbers of a plurality of sensors corresponding to each action device. Preferably, the planar image is further positioned to the corresponding action device inside the apparatus by selecting a code or a number capable of representing the corresponding action device or sensor, and the planar image related thereto is displayed, and at the same time, the second graphic processor 400 is capable of further switching the stereoscopic model image to the inside of the apparatus in response to the click operation and according to a preset corresponding rule, so that a manager can know the operation state inside the apparatus, thereby more timely and accurately monitoring the operation state of the waste separation system 10 or the temperature control system 20.

According to a preferred embodiment, the plane image output by the first graphic processor 300 and the stereoscopic model image output by the second graphic processor 400 can be switched in real time, and the plane image and the stereoscopic model image can be displayed on the same screen. Specifically, in addition to clicking on a device in the planar image or selecting a code or number that can represent a corresponding influencing device or sensor, a corresponding code may also be entered directly in a search field of the planar image to directly locate the stereoscopic image to the relevant device or influencing device. Secondly, the same screen display of the plane image and the stereo model image includes but is not limited to the modes of up-down screen and left-right screen.

According to a preferred embodiment, when the manager changes the graphic data of the waste separation system 10 or the temperature control system 20 and/or the attribute information of each action device 200 in the waste separation system 10 or the temperature control system 20 when viewing the operation state of each device in the waste separation system 10 or the temperature control system 20 through the planar image and/or the stereoscopic model image, the first graphic processor 300 and/or the second graphic processor 400 synchronously updates the image thereof and the related state information included in the image in response to the change, so that the first graphic processor 300 and/or the second graphic processor 400 can display the real-time image corresponding to the waste separation system 10 or the temperature control system 20 and each device in the system to the manager in a manner of keeping the image and the attribute information consistent. Unlike the conventional serial mode, the synchronous on-screen mode of operation significantly reduces the impact of data delay transmission, display on the operating condition determination and optimization of waste separation system 10 or temperature control system 20.

According to a preferred embodiment, when the first graphic processor 300 and/or the second graphic processor 400 outputs the corresponding plane image and/or the stereoscopic model image, the control unit 100 will synchronously establish a past database, a current database and an expected database for describing the temporal/spatial attributes of each action device 200 based on the correlation between the analog image and the attribute information included in the analog image. Specifically, the temporal and/or spatial attributes included in the equipment are constantly being updated in connection with the operation of the waste separation system 10 or the temperature control system 20. The time attributes of a device include its corresponding time location, the start runtime and the end runtime of the device, either static or dynamic. Further, for a stationary object, the spatial attributes of the device may include the spatial extent, spatial location, and outline dimensions of the device itself. For dynamic objects, such as the effector inside the apparatus, the spatial attributes may include the spatial extent, spatial location, and corresponding outline dimensions of the effector.

According to a preferred embodiment, the past database, the current database, and the prospective database of each affector 200 are also continuously updated as each affector 200 continues to operate. For example, the control unit 100 can summarize the current plane image and/or stereo model image into the past database based on a certain time period, the current database needs to have high timeliness, for example, hundreds of thousands of refresh times per second, and for the plane image and/or stereo model image simulation image which is not refreshed in time, the plane image and/or stereo model image simulation image can be automatically categorized into the past database according to the preset time period. The expected database, which is used to characterize changes that may have occurred in the future in the reaction device 200, is derived by the control unit 100 by combining the past and current databases of the reaction device 200 and by means of simulation calculations.

Further, based on the past plane image/stereoscopic model image and the current plane image/stereoscopic model image for representing the operation state of the internal working device of the apparatus, the control unit 100 can analyze and compare the past image and the current image, and simulate an operation state image which may not appear in each working device 200 by an algorithm by combining attribute information and graphic data information included in the images. Especially for the role devices inside the equipment, it is necessary to establish a database of expectations associated therewith so that the administrator can optimize the operating environment of the equipment or system in advance according to the changes in the operating status of the role devices 200 reflected in the database of expectations. In particular, changes in the operating conditions of any equipment, especially minor changes in its internal operating means, can have an effect on other equipment upstream and downstream thereof, which in turn can affect efficient and stable operation of the entire waste separation system 10 or temperature control system 20. Therefore, knowing the possible fault risk of the equipment in advance can help a manager to avoid major accidents in time, and meanwhile, the manager can adjust the relevant operation parameters of the equipment with possible faults and the equipment adjacent to the equipment to ensure the continuous and stable operation of the waste separation system 10 or the temperature control system 20, so that the separation and recovery effect of metal waste is improved, and the probability of dust fire is reduced.

It should be noted that the above-mentioned embodiments are exemplary, and that those skilled in the art, having benefit of this disclosure, may devise various solutions which are within the scope of this disclosure and are within the scope of the invention. It should be understood by those skilled in the art that the present specification and figures are illustrative only and are not limiting upon the claims. The scope of the invention is defined by the claims and their equivalents.
