Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically to an industrial heating component. Background Technology

[0002] In related technologies, industrial heating equipment typically incorporates an insulation layer inside the furnace to reduce heat loss during operation, thus achieving a heat preservation effect. However, the insulation layer also absorbs heat, causing its temperature to rise. Since the temperature of the insulation layer is not effectively utilized, there is a problem of energy waste.

[0003] In some technologies, pipes are laid in the insulation layer to achieve waste heat recovery, but the following problems exist: 1. After the industrial heating equipment stops operating, the liquid in the pipe is difficult to drain, which can easily lead to pressure rise and safety risks; 2. The liquid temperature rise is insufficient, and the heat utilization effect is limited; 3. The workload of pipe installation and maintenance is large. Utility Model Content

[0004] The purpose of this invention is to provide an industrial heating component to solve the problems of existing technologies, such as difficulty in draining liquid from pipes laid in insulation layers, low waste heat recovery efficiency, and high operating costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An industrial heating assembly includes: an industrial heating device comprising a furnace body having a hot air passage and a rigid insulation layer; an energy-absorbing element disposed on the rigid insulation layer, the energy-absorbing element having a receiving cavity for containing a heat-conducting medium, the receiving cavity extending through the energy-absorbing element to form an outlet and a vent, the vent being located at the bottom of the energy-absorbing element and the outlet being higher than the vent; a parameter detection element for detecting at least one of the air pressure inside the energy-absorbing element, the heating time of the heat-conducting medium inside the energy-absorbing element, and the temperature of the heat-conducting medium; a vent valve communicating with the vent; an outlet valve communicating with the outlet; and a control unit connected to the parameter detection element and the outlet valve, the control unit controlling the opening and closing of the outlet valve based on the detection result of the parameter detection element.

[0007] According to the above technical means, during the operation of industrial heating equipment, high-temperature gas is present in the hot air channel. This high-temperature gas exchanges heat with the inner circumference of the furnace body, thus the rigid insulation layer inside the furnace body is also at a high temperature. An energy-absorbing component is placed on the rigid insulation layer, which supports and fixes the position of the energy-absorbing component. The energy-absorbing component absorbs heat from the rigid insulation layer to heat the heat-conducting medium inside it. Parameter detection components can detect at least one of the following: the air pressure inside the energy-absorbing component, the heating time of the heat-conducting medium inside the component, and the temperature of the heat-conducting medium. Based on these parameters, it is determined whether the heat-conducting medium has absorbed sufficient heat, for example, when the temperature of the heat-conducting medium reaches a preset temperature, such as 85℃~95℃. Alternatively, when the heat transfer medium has been heated for a preset time, such as 10 to 30 minutes, or when the pressure inside the energy-absorbing component rises to a preset pressure, it indicates that the heat transfer medium has absorbed sufficient heat, resulting in high waste heat recovery efficiency. The control unit then opens the outlet valve, allowing the heat transfer medium to flow out of the energy-absorbing component. The outlet of the energy-absorbing component can be connected to an insulation box or a heat exchanger. The heat transfer medium can be stored in the insulation box or exchange heat with other equipment in the heat exchanger. Finally, the heat from the heat transfer medium is used for indoor heating, heating domestic water, etc. When the heat transfer medium is water, it can also be directly used for bathing, washing clothes, and other daily activities, improving the heat utilization rate of the heat transfer medium. When the industrial heating equipment stops operating, the vent valve can be opened. The vent valve can be opened manually or electrically, allowing the heat transfer medium inside the energy-absorbing component to flow out through the vent. The heat transfer medium can be stored in a container to avoid environmental pollution and facilitate reuse, saving energy and protecting the environment. Draining or nearly draining the heat transfer medium from the energy-absorbing component avoids high-pressure risks and ensures safety.

[0008] Furthermore, the industrial heating assembly also includes a start-stop unit, which is connected to the industrial heating equipment and the control unit, for controlling the start-stop of the industrial heating equipment, and the control unit controls the opening and closing of the vent valve according to the working status of the start-stop unit.

[0009] Based on the above technical means, the on / off state of the vent valve is linked to the working status of the start / stop unit, which can prevent the vent valve from being forgotten to be opened or closed, thus improving the level of intelligence, enhancing safety, and preventing the waste of heat transfer medium.

[0010] Furthermore, there are multiple energy-absorbing elements, which are spaced apart along the circumference of the furnace body.

[0011] Based on the above-mentioned technical means, the energy-absorbing components can recover waste heat from various areas of the furnace body, improve the waste heat recovery efficiency, and the volume of a single energy-absorbing component does not need to be too large, which can reduce the processing difficulty of the energy-absorbing component, improve production efficiency and service life, and multiple energy-absorbing components can also play a supporting role for the furnace body, improving the structural strength of the furnace body.

[0012] Furthermore, the parameter detection device is used to detect the parameters of at least one of the energy-absorbing devices; and / or, the plurality of outlets are all connected to the outlet valve; and / or, the plurality of vent ports are all connected to the vent valve.

[0013] Based on the above technical means, there is no need to set up multiple parameter detection components, outlet valves and vent valves, which improves the reuse rate of parts, reduces the number of parts, and lowers costs.

[0014] Furthermore, the energy-absorbing component is also provided with an inlet, and the industrial heating assembly also includes an inlet valve, which is connected to the inlet. The control unit is connected to the inlet valve and is used to control the opening and closing of the inlet valve.

[0015] According to the above-mentioned technical means, the heat transfer medium inside the energy absorption component is discharged from the outlet. The control unit can control the inlet valve to open so as to inject new heat transfer medium into the energy absorption component, automatically replenish the heat transfer medium, and achieve continuous circulation heating to improve waste heat efficiency.

[0016] Furthermore, the industrial heating assembly also includes a liquid level detection element, connected to the energy-absorbing element, used to detect the height of the heat-conducting medium inside the energy-absorbing element.

[0017] Based on the above technical means, the sufficiency of the heat-conducting medium in the energy-absorbing component can be improved to enhance the waste heat recovery efficiency, and excessive heat-conducting medium in the energy-absorbing component can be avoided to prevent excessive pressure and improve safety.

[0018] Furthermore, the cavity is provided with a partition, which is perpendicular to the vertical direction. The inlet is lower than the outlet, and the partition is located between the inlet and the outlet in the vertical direction.

[0019] Based on the above technical means, on the one hand, the structural strength of the energy-absorbing component can be increased, and the probability of the energy-absorbing component being damaged under the pressure of the heat-conducting medium can be reduced. On the other hand, it can prevent the low-temperature heat-conducting medium entering from the inlet from rushing directly to the outlet, which would cause the temperature of the heat-conducting medium flowing out of the outlet to be too high, thus improving hot water convection.

[0020] Furthermore, the energy-absorbing component is also provided with a pressure relief port, and the industrial heating assembly also includes a pressure relief valve, which is connected to the pressure relief port. The pressure relief valve switches on and off states according to the pressure difference between the inside and outside of the energy-absorbing component.

[0021] According to the above technical means, when the pressure inside the energy-absorbing component is too high, the pressure relief valve opens under the action of pressure to balance the internal and external air pressure of the energy-absorbing component and prevent the energy-absorbing component from being damaged under the action of pressure.

[0022] Furthermore, the inner circumferential surface of the energy-absorbing component is provided with an anti-scaling coating; and / or, the energy-absorbing component includes an outer casing and an inner casing, the inner casing is detachably disposed within the outer casing, the furnace body is provided with a disassembly port, and the inner casing can pass through the disassembly port.

[0023] Based on the above-mentioned technical means, it is possible to reduce scale on energy-absorbing components, ensure waste heat recovery efficiency, and reduce maintenance costs.

[0024] Furthermore, the industrial heating assembly also includes a pump body connected to the outlet for pumping the heat-conducting medium inside the energy-absorbing element; and / or, the outlet valve is a one-way valve, which prevents the heat-conducting medium from flowing into the energy-absorbing element from the outlet.

[0025] Based on the above technical means, the outflow efficiency of high-temperature heat transfer medium can be improved, and the backflow of high-temperature heat transfer medium can be avoided, thereby improving the flow efficiency of heat transfer medium and thus improving the waste heat recovery efficiency.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0039] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0040] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0041] This utility model embodiment proposes an industrial heating component 1, which includes an industrial heating device 100, an energy-absorbing component 200, a parameter detection component 300, an exhaust valve 400, an outlet valve 500, and a control unit 600.

[0042] Industrial heating equipment 100 includes a furnace body 110, which has a hot air passage 111 and a rigid insulation layer 113. An energy-absorbing element 200 is disposed on the rigid insulation layer 113. The energy-absorbing element 200 has a receiving cavity 290 for containing a heat-conducting medium. The receiving cavity 290 penetrates the energy-absorbing element 200 to form an outlet 210 and a vent 220. The vent 220 is located at the bottom of the energy-absorbing element 200, and the outlet 210 is higher than the vent 220. A parameter detection element 300 detects at least one of the following: air pressure inside the energy-absorbing element 200, heating time of the heat-conducting medium inside the energy-absorbing element 200, and temperature of the heat-conducting medium. A vent valve 400 is connected to the vent 220, and an outlet valve 500 is connected to the outlet 210. A control unit 600 is connected to the parameter detection element 300 and the outlet valve 500, and the control unit 600 controls the opening and closing of the outlet valve 500 based on the detection results of the parameter detection element 300.

[0043] For example, the shape of the energy-absorbing component 200 can be customized according to the internal space of the rigid insulation layer 113. The energy-absorbing component 200 can be constructed as a rectangle, cylinder, or polygon to ensure that the energy-absorbing component 200 fits snugly with the rigid insulation layer 113, increasing the heat exchange area and improving the waste heat recovery efficiency. The material of the energy-absorbing component 200 can be a high-temperature resistant and corrosion-resistant metal, such as stainless steel or nickel-based alloys.

[0044] The rigid insulation layer 113 can prevent the heat of the industrial heating equipment 100 from escaping into the air, thereby reducing energy consumption. The industrial heating equipment 100 can be a regenerator, glass furnace, or other equipment with a rigid insulation layer 113 that can be used in industrial production.

[0045] The parameter detection device 300 is connected to the control unit 600 via a signal line. When the parameter detection device 300 can detect the air pressure inside the energy-absorbing component 200, the parameter detection device 300 may include a pressure sensor; when the parameter detection device 300 can detect the temperature of the heat-conducting medium, the parameter detection device 300 may include a temperature sensor, such as a thermocouple or PT100; when the parameter detection device 300 can detect the heating time of the heat-conducting medium, the parameter detection device 300 may include a timer, clock, etc.

[0046] It should be noted that the heating time of the heat transfer medium is calculated from the moment a certain amount of heat transfer medium is injected into the energy absorption element 200 and the injection of heat transfer medium is stopped, and the calculation stops when the outlet valve 500 is opened.

[0047] Thermal transfer media can include liquids with thermal conductivity such as water, thermal oil, and antifreeze.

[0048] When the industrial heating equipment 100 is running, the hot air channel 111 contains high-temperature gas, which exchanges heat with the inner circumferential surface of the furnace body 110. Therefore, the rigid insulation layer 113 inside the furnace body 110 is also at a high temperature. The energy-absorbing component 200 is placed on the rigid insulation layer 113, which supports and fixes the position of the energy-absorbing component 200. The energy-absorbing component 200 can absorb the heat from the rigid insulation layer 113 to heat the heat-conducting medium inside the energy-absorbing component 200. The parameter detection component 300 can detect at least one of the following: the air pressure inside the energy-absorbing component 200, the heating time of the heat-conducting medium inside the energy-absorbing component 200, and the temperature of the heat-conducting medium. Based on the above parameters, it is determined whether the heat-conducting medium has absorbed sufficient heat, for example, when the temperature of the heat-conducting medium reaches a preset temperature, such as 85°C. When the temperature is between ℃ and 95℃, or when the heat transfer medium is heated for a preset time, such as 10 to 30 minutes, or when the pressure inside the energy-absorbing component 200 rises to a preset pressure, it indicates that the heat transfer medium has absorbed sufficient heat and has high waste heat recovery efficiency. The control unit 600 controls the outlet valve 500 to open, and the heat transfer medium can flow out of the energy-absorbing component 200 through the outlet 210. The outlet 210 of the energy-absorbing component 200 can be connected to an insulation box or a heat exchanger. The heat transfer medium can enter the insulation box for storage, or it can enter the heat exchanger to exchange heat with other equipment. Finally, the heat from the heat transfer medium is used for indoor heating, heating domestic water, etc. When the heat transfer medium is water, it can also be directly used for bathing, washing clothes, and other daily life scenarios, improving the heat utilization rate of the heat transfer medium.

[0049] When the industrial heating equipment 100 stops operating, the vent valve 400 can be opened. The vent valve 400 can be opened manually or electrically. The heat transfer medium inside the energy absorption component 200 flows out of the energy absorption component 200 through the vent port 220. The heat transfer medium can be stored in a container to avoid environmental pollution and facilitate continued use next time. It is energy-saving and environmentally friendly. The heat transfer medium inside the energy absorption component 200 is emptied or almost emptied to avoid high pressure risks and ensure safety.

[0050] For example, the rigid insulation layer 113 has an installation area. The distance between the inner side of the installation area and the inner circumferential surface of the furnace body 110 is H1, and the distance between the outer side of the installation area and the inner circumferential surface of the furnace body 110 is H2. The thickness of the furnace body 110 can be H3, H1 can be 1 / 3 of H3, and H2 can be 2 / 3 of H3. The energy-absorbing component 200 is located in the installation area. In this way, the inner circumferential surface of the furnace body 110 is generally about 500°C, and the energy-absorbing component 200 is located in an area of ​​about 150°C.

[0051] In some embodiments, such as Figure 2 As shown, the industrial heating assembly 1 also includes a start-stop unit 130, which is connected to the start-stop of the industrial heating equipment 100. The control unit 600 controls the opening and closing of the vent valve 400 according to the working status of the start-stop unit 130.

[0052] Specifically, when the start-stop unit 130 controls the industrial heating equipment 100 to start moving, the control unit 600 receives the corresponding electrical signal. The control unit 600 can control the vent valve 400 to close, and then inject a heat-conducting medium into the energy-absorbing component 200 to absorb the waste heat of the industrial heating equipment 100.

[0053] When the start / stop unit 130 controls the industrial heating equipment 100 to stop moving, the control unit 600 receives the corresponding electrical signal and can control the vent valve 400 to open, so that the heat transfer medium in the energy absorption component 200 flows out from the vent port 220, avoiding pressure increase and improving safety.

[0054] In this way, the on / off state of the vent valve 400 is linked to the working state of the start / stop unit 130, which can prevent the vent valve 400 from being forgotten to open or close, thus improving the level of intelligence, enhancing safety, and preventing the waste of heat transfer medium.

[0055] In some embodiments, such as Figure 1 As shown, there are multiple energy-absorbing components 200, which are spaced apart along the circumference of the furnace body 110. In this way, the energy-absorbing components 200 can recover waste heat from various areas of the furnace body 110, improving waste heat recovery efficiency. Furthermore, the volume of a single energy-absorbing component 200 does not need to be too large, which reduces the processing difficulty of the energy-absorbing component 200, improves production efficiency and service life, and the multiple energy-absorbing components 200 can also provide support for the furnace body 110, improving the structural strength of the furnace body 110.

[0056] In some embodiments, such as Figure 2 As shown, the parameter detection element 300 is used to detect the parameters of at least one energy-absorbing element 200. Since the temperature in each area of ​​the furnace body 110 is basically the same, detecting the parameters of one energy-absorbing element 200 can roughly obtain the parameters of the other energy-absorbing elements 200. In this way, there is no need to set up multiple parameter detection elements 300, which improves the reuse rate of parameter detection elements 300, reduces the number of parts, and reduces costs.

[0057] Of course, in some embodiments, there are also multiple parameter detection elements 300, and multiple parameter detection elements 300 are set one-to-one with multiple energy absorption elements 200. Each parameter detection element 300 detects the parameters of its corresponding energy absorption element 200.

[0058] In some embodiments, such as Figure 2As shown, multiple outlets 210 are all connected to outlet valve 500. It can be understood that the industrial heating component 1 includes an outlet pipe, which has a main outlet line and multiple outlet branches. The multiple outlets 210 are connected to the multiple outlet branches in a one-to-one correspondence. The main outlet line is connected to outlet valve 500, so that all multiple outlets 210 are connected to outlet valve 500.

[0059] This eliminates the need for multiple outlet valves 500, increases the reusability of outlet valves 500, reduces the number of parts, and lowers costs.

[0060] Of course, in some embodiments, there are also multiple outlet valves 500, and multiple outlet valves 500 are set one-to-one with multiple energy-absorbing elements 200, with each outlet valve 500 connected to the outlet 210 of its corresponding energy-absorbing element 200.

[0061] In some embodiments, such as Figure 2 As shown, multiple vent ports 220 are all connected to the vent valve 400. It can be understood that the industrial heating assembly 1 includes a vent pipe with a main vent line and multiple vent branches. The multiple vent ports 220 are connected to the multiple vent branches in a one-to-one correspondence. The main vent line is connected to the vent valve 400, so that all multiple vent ports 220 are connected to the vent valve 400.

[0062] This eliminates the need for multiple vent valves 400, increases the reusability of vent valves 400, reduces the number of parts, and lowers costs.

[0063] Of course, in some embodiments, there are also multiple vent valves 400, and multiple vent valves 400 are set one-to-one with multiple energy-absorbing elements 200. Each vent valve 400 is connected to the vent port 220 of its corresponding energy-absorbing element 200.

[0064] In some embodiments, such as Figure 2 As shown, the energy-absorbing component 200 is also provided with an inlet 230, and the industrial heating component 1 also includes an inlet valve 510, which is connected to the inlet 230. The control unit 600 is connected to the inlet valve 510 and is used to control the opening and closing of the inlet valve 510.

[0065] For example, inlet 230 can be connected to a storage device containing a heat-conducting medium.

[0066] The heat transfer medium inside the energy absorption element 200 is discharged from the outlet 210. The control unit 600 can control the inlet valve 510 to open, so as to inject new heat transfer medium into the energy absorption element 200. The heat transfer medium is automatically replenished, which has a high degree of intelligence, realizes continuous circulation heating, and improves waste heat efficiency.

[0067] The inlet valve 510 can be integrated with a one-way function to prevent the heat transfer medium inside the energy absorption component 200 from flowing out from the inlet 230.

[0068] In some embodiments, such as Figure 2 As shown, the industrial heating assembly 1 also includes a liquid level detection element 700, which is connected to the energy absorption element 200. The liquid level detection element 700 is used to detect the height of the heat-conducting medium inside the energy absorption element 200.

[0069] The liquid level detection element 700 can be an electronic liquid level sensor or a transparent high-temperature resistant tube. The transparent high-temperature resistant tube is connected to the energy absorption element 200 and extends out of the furnace body 110 so that the operator can directly observe the liquid level.

[0070] Based on the detection results from the liquid level detection device 700, the operator can actively inject heat-conducting medium into the energy-absorbing component 200. Furthermore, the liquid level detection device 700 can also be electrically connected to the control unit 600, which can control the opening and closing of the inlet valve 510 based on the detection results from the liquid level detection device 700, thereby automatically injecting heat-conducting medium into the energy-absorbing component 200.

[0071] This ensures sufficient replenishment of heat-conducting medium within the energy-absorbing component 200, thereby improving waste heat recovery efficiency and preventing excessive pressure caused by excessive heat-conducting medium within the energy-absorbing component 200, thus enhancing safety.

[0072] Furthermore, such as Figure 3 and Figure 4 As shown, the energy-absorbing component 200 has a partition 240 inside, which is perpendicular to the vertical direction. The inlet 230 is lower than the outlet 210, and the partition 240 is located between the inlet 230 and the outlet 210 in the vertical direction.

[0073] By setting the baffle 240, on the one hand, the structural strength of the energy-absorbing component 200 can be increased, and the probability of the energy-absorbing component 200 being damaged under the pressure of the heat-conducting medium can be reduced. On the other hand, it can prevent the low-temperature heat-conducting medium entering from the inlet 230 from directly rushing to the outlet 210, which would cause the temperature of the heat-conducting medium flowing out of the outlet 210 to be too high, thus improving the hot water convection.

[0074] In some embodiments, such as Figure 2 As shown, the energy-absorbing component 200 is also provided with a pressure relief port 250, and the industrial heating component 1 also includes a pressure relief valve 800, which is connected to the pressure relief port 250. The pressure relief valve 800 switches between on and off states according to the pressure difference inside and outside the energy-absorbing component 200.

[0075] The pressure relief valve 800 may include an expansion valve.

[0076] In this way, when the pressure inside the energy-absorbing component 200 is too high, the pressure relief valve 800 opens under the action of pressure, balancing the internal and external air pressure of the energy-absorbing component 200 and preventing the energy-absorbing component 200 from being damaged under the action of pressure.

[0077] In some embodiments, such as Figure 3 As shown, the inner circumferential surface of the energy-absorbing component 200 is provided with an anti-scaling coating 260. This prevents excessive scale buildup inside the energy-absorbing component 200 from affecting its energy absorption efficiency, ensuring waste heat recovery efficiency, and reducing maintenance costs.

[0078] In some embodiments, such as Figure 4 As shown, the energy-absorbing component 200 includes an outer casing 270 and an inner casing 280. The inner casing 280 is detachably disposed inside the outer casing 270. The furnace body 110 is provided with a disassembly port, through which the inner casing 280 can pass.

[0079] In this way, the inner casing 280 can be removed separately from the furnace body 110, and the inner casing 280 can be cleaned to reduce scale on the inner casing 280, ensure waste heat recovery efficiency, and reduce maintenance costs.

[0080] In some embodiments, such as Figure 2 As shown, the industrial heating assembly 1 also includes a pump body 900, which is connected to the outlet 210. The pump body 900 is used to pump the heat-conducting medium inside the energy-absorbing component 200. This improves the outflow efficiency of the high-temperature heat-conducting medium.

[0081] In some embodiments, the outlet valve 500 is a one-way valve that prevents the heat transfer medium from flowing from the outlet 210 into the energy absorption element 200. The outlet valve 500 and the pump body 900 can be integrated into a single structure. This avoids the backflow of the high-temperature heat transfer medium, improves the flow efficiency of the heat transfer medium, and thus improves the waste heat recovery efficiency.

[0082] The working process of industrial heating component 1 is described below with reference to the accompanying drawings:

[0083] First, the start-stop unit 130 controls the industrial heating equipment 100 to start running. The hot air channel 111 contains high-temperature gas, and the rigid insulation layer 113 in the furnace body 110 heats up. At the same time, the control unit 600 receives the electrical signal from the start-stop unit 130, controls the vent valve 400 to close, and controls the inlet valve 510 to open, injecting heat-conducting medium into the energy-absorbing component 200 through the inlet 230. The heat-conducting medium absorbs the heat of the rigid insulation layer 113.

[0084] Then, the parameter detection unit 300 continuously detects parameters such as the air pressure inside the energy-absorbing component 200, the heating time of the heat-conducting medium inside the energy-absorbing component 200, and the temperature of the heat-conducting medium. When the pressure, time, or temperature meets the requirements, the control unit 600 receives the electrical signal from the parameter detection unit 300 and controls the outlet valve 500 to open, so that the high-temperature heat-conducting medium flows out from the outlet 210 to the outside of the energy-absorbing component 200.

[0085] Next, when the liquid level detection device 700 detects that the liquid level of the energy absorber 200 has reached a low point, the control unit 600 receives the electrical signal from the liquid level detection device 700, controls the outlet valve 500 to close, and controls the inlet valve 510 to open, injecting heat transfer medium into the energy absorber 200 through the inlet 230, and repeats the above working process. During this working process, if the pressure inside the energy absorber 200 is too high, the pressure relief valve 800 opens to balance the internal and external pressure of the energy absorber 200.

[0086] Finally, the start-stop unit 130 controls the industrial heating equipment 100 to stop operating. The control unit 600 receives the electrical signal from the start-stop unit 130, controls the vent valve 400 to open, and controls the inlet valve 510 and outlet valve 500 to close, so as to vent the heat-conducting medium in the energy-absorbing component 200 through the vent port 220.
