Description

Technical Field

[0001] This utility model belongs to the field of fresh air equipment technology, and in particular relates to a fresh air dehumidification device and a glass processing system. Background Technology

[0002] In the deep processing of laminated glass, the glass substrate needs to be heated and softened in a hot bending furnace to achieve the desired shape. After being formed, the glass products need to be transferred to a constant temperature and humidity environment for further processing. This is usually done in a designated workshop where the humidity is controlled by a fresh air dehumidification system.

[0003] Current fresh air dehumidification equipment mainly consists of a regenerative dehumidifier and an air heater: the regenerative dehumidifier is responsible for adsorbing and removing moisture from the environment, while the air heater provides a heat source for the dehumidifier to complete the evaporation of moisture. Actual measurement data shows that the air heater accounts for more than 95% of the total system energy consumption. Its operation mode of treating adsorbed moisture through thermal evaporation is a key factor contributing to the overall increase in production costs.

[0004] However, current fresh air dehumidification equipment is energy-intensive, and when the regenerator or other components are damaged and need repair, the power needs to be cut off and the machine needs to be shut down for maintenance, which affects production efficiency. Utility Model Content

[0005] The purpose of this application is to provide a fresh air dehumidification device, which aims to solve the problem of how to reduce the energy consumption of the fresh air dehumidification device and improve production efficiency.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] In a first aspect, a fresh air dehumidification device is provided for use in conjunction with an external heat source. The fresh air dehumidification device includes: an exhaust fan, a duct assembly, a control component, and a dehumidifier located within a processing workshop. The duct assembly includes a first duct and a second duct. One end of the first duct is connected to the exhaust fan, and the heat source is located at the other end of the first duct. The heat source is used to heat the air within the first duct. The two ends of the second duct are respectively connected to the exhaust fan and the dehumidifier. The dehumidifier has a working state and a shutdown state. When the dehumidifier is in the working state, the control component allows the exhaust fan to drive the air within the first duct to the second duct, and the air flows into the dehumidifier. When the dehumidifier is in the shutdown state, the control component restricts the flow of air from the first duct into the second duct. Two dehumidifiers are provided, with at least one dehumidifier in the working state.

[0008] In some embodiments, the control component includes a first control valve disposed on the first duct. When the dehumidifier is in a stopped state, the first control valve blocks the first duct, and when the dehumidifier is in the working state, the first control valve opens the first duct.

[0009] In some embodiments, the second duct includes a main pipe connected to the exhaust fan and two branch pipes connected to the main pipe, with the two branch pipes respectively connected to the two dehumidifiers.

[0010] In some embodiments, the duct assembly further includes a third duct, one end of which is connected to one of the branch pipes, and the other end of which extends to the outside of the processing workshop and is provided with a fresh air window. When the dehumidifier is in operation, the fresh air window is in a closed state, and when the dehumidifier is in a stopped state, the fresh air window is in an open state. Each of the branch pipes is provided with the third duct.

[0011] In some embodiments, the control component includes a second control valve located in the third air duct, the second control valve being used to control the fresh air window to be in the open state or in the closed state.

[0012] In some embodiments, the dehumidifier includes a main unit, a rotor, and a heater, with the air in the second duct passing sequentially through the heater and the rotor.

[0013] In some embodiments, the duct assembly further includes an exhaust duct, one end of which is connected to the dehumidifier and the other end of which extends outside the processing workshop. The exhaust duct is used to discharge the air flowing through the impeller.

[0014] In some embodiments, the induced draft fan is a centrifugal fan.

[0015] In some embodiments, the duct assembly further includes an exhaust pipe connected to the first duct. When the dehumidifier is in operation, the exhaust pipe is closed; when the dehumidifier is off, air in the first duct flows into the exhaust pipe.

[0016] In a second aspect, a glass processing system is provided, which includes the aforementioned fresh air dehumidification equipment. The glass processing system also includes a hot bending machine located at one end of the first air duct.

[0017] The beneficial effects of this application are as follows: by using a hot bending machine in conjunction with a fresh air dehumidification device, the heat from the hot bending machine is transferred to the air in the first air duct using an exhaust fan and duct assembly, and then the air in the first air duct is guided to the dehumidifier through the second air duct for regeneration and dehumidification. This can effectively reduce the energy consumption of the dehumidifier itself and achieve the purpose of energy saving. At the same time, at least two dehumidifiers are set up and at least one is in working condition. When one dehumidifier is stopped for maintenance, the other dehumidifier can continue to run, thereby avoiding overall shutdown, improving production efficiency and maintaining the stability of a constant humidity environment.

[0027] Please see Figures 1 to 3 This application provides a fresh air dehumidification device and a glass processing system. The fresh air dehumidification device is used in conjunction with an external heat source to solve the problems of high energy consumption and the need to shut down the machine for maintenance, which affects production efficiency. The heat source can be a hot bending machine, which can discharge high-temperature gas during operation. The temperature range of the discharged high-temperature gas is 80-130°C, depending on the location of the air outlet.

[0028] Please see Figures 1 to 3 The fresh air dehumidification equipment includes: an exhaust fan 20, a duct assembly 10, a control assembly 30, and a dehumidifier 40 located in the processing workshop; the processing workshop can be a closed space, and the glass processed by the hot bending furnace can be placed in the processing workshop, and the processing workshop maintains stable environmental humidity and temperature through the dehumidifier 40.

[0029] Please see Figures 1 to 3 The duct assembly 10 includes a first duct 11 and a second duct 12. One end of the first duct 11 is connected to the exhaust fan 20, and the hot bending machine is located at the other end of the first duct 11. The hot bending machine is used to heat the air inside the first duct 11. It can be understood that the hot bending machine can directly discharge its own high-temperature gas into the first duct 11 to heat the air inside the first duct 11, or the hot bending machine can heat the first duct 11 with its own high-temperature gas, and the temperature of the air inside the first duct 11 will rise through heat conduction.

[0030] Please see Figures 1 to 3The two ends of the second duct 12 are respectively connected to the exhaust fan 20 and the dehumidifier 40; wherein, the dehumidifier 40 has a working state and a shutdown state. When the dehumidifier 40 is in the working state, the control component 30 allows the exhaust fan 20 to drive the air in the first duct 11 to the second duct 12 and make the air flow into the dehumidifier 40; since the air entering the dehumidifier 40 is first heated by the hot bending machine, the amount of heating required by the dehumidifier 40 can be reduced, so that the dehumidifier 40 only needs a small amount of energy to make the air reach the required temperature, thus reducing energy consumption.

[0031] Please see Figures 1 to 3 When the dehumidifier 40 is in the stopped state, the control component 30 restricts the flow of air from the first air duct 11 into the second air duct 12, thereby preventing the dehumidifier 40 from being damaged by high-temperature gas. Two dehumidifiers 40 are provided, with at least one dehumidifier 40 in the operating state. It is understood that both dehumidifiers 40 can be in operating state simultaneously, with the second air duct 12 simultaneously supplying air to both dehumidifiers 40 independently, thus fully utilizing the waste heat of the hot bending machine. Alternatively, one dehumidifier 40 can be in operating state while the other is in standby, maintenance, or repair state, thereby avoiding downtime that would affect normal production. It is also understood that three or more dehumidifiers 40 can be provided; there is no limitation here, and the selection can be made according to the actual situation.

[0032] Please see Figures 1 to 3 This application embodiment uses a hot bending machine in conjunction with a fresh air dehumidification device. The heat from the hot bending machine is transferred to the air in the first air duct 11 by the exhaust fan 20 and the air duct assembly 10. The air in the first air duct 11 is then guided to the dehumidifier 40 through the second air duct 12 for regeneration dehumidification. This can effectively reduce the energy consumption of the dehumidifier 40 itself and achieve the purpose of energy saving. At the same time, at least two dehumidifiers 40 are set up and at least one is in working condition. When one dehumidifier 40 is stopped for maintenance, the other dehumidifier 40 can continue to run, thereby avoiding overall shutdown, improving production efficiency and maintaining the stability of a constant humidity environment.

[0033] Please see Figures 1 to 3 In some embodiments, the control component 30 includes a first control valve 31 disposed on the first air duct 11. When the dehumidifier 40 is in the off state, the first control valve 31 blocks the first air duct 11. When the dehumidifier 40 is in the working state, the first control valve 31 opens the first air duct 11.

[0034] Optionally, the first control valve 31 is a pneumatic damper. The main components of the pneumatic damper, such as the valve body and valve plate, are typically made of heat-resistant alloy steel, stainless steel, or have a high-temperature resistant coating. Sealing materials can be heat-resistant graphite, ceramic fiber, etc., enabling long-term stable operation in environments such as high-temperature flue gas and hot air ducts. It can generally withstand 200℃~450℃, and up to 800℃ or higher. The actuator of the pneumatic damper is fast-acting and simple in structure, driven by compressed air, with a stable power source that is not easily affected by high-temperature environments. The valve mechanism often uses wear-resistant bearings and high-temperature resistant seals, combined with mechanical limiters and pneumatic buffer structures, enabling it to maintain consistent action and sealing performance during high-frequency opening and closing and long-term operation, thus possessing the characteristics of high-temperature resistance and durability.

[0035] It is understandable that a first control valve 31 is provided on both sides of the exhaust fan 20 to improve the reliability of the cut-off and prevent the first air duct 11 from supplying high-temperature air to the dehumidifier 40 when the dehumidifier 40 is in a stopped state, which would cause damage to the dehumidifier 40.

[0036] Please see Figures 1 to 3 In some embodiments, the second duct 12 includes a main pipe 121 connected to the exhaust fan 20 and two branch pipes 122 connected to the main pipe 121, and the two branch pipes 122 are respectively connected to the two dehumidifiers 40.

[0037] Please see Figures 1 to 3 Optionally, two dehumidifiers 40 can be connected in parallel to the main pipe 121 via two branch pipes 122, so that the two dehumidifiers 40 can operate independently and the main pipe 121 can independently supply air to the two branch pipes 122, which can realize the splitting and parallel supply of air, improve the overall capacity and efficiency of dehumidification treatment, and ensure that the fresh air dehumidification equipment can better maintain the constant humidity environment in the processing workshop under the cooperation of multiple machines.

[0038] Please see Figures 1 to 3 Optionally, each branch pipe 122 is equipped with a pneumatic air valve. The pneumatic air valve can control the cut-off and conduction of the corresponding branch pipe 122. A control cylinder knob and a cylinder magnetic switch can also be added to detect the valve position signal of the pneumatic air valve, thereby facilitating on-site operation and observation, ensuring the safety of the dehumidifier 40 in standby mode, that is, the waste heat of the hot bending furnace cannot enter the rotor 42 of the dehumidifier 40 in the shutdown mode, thus extending the service life of the dehumidifier 40.

[0039] Please see Figures 1 to 3In some embodiments, the duct assembly 10 further includes a third duct 13, one end of which is connected to one of the branch pipes 122, and the other end of which extends to the outside and is provided with a fresh air window 24. When the dehumidifier 40 is in operation, the fresh air window 24 is in a closed state, and when the dehumidifier 40 is in a stopped state, the fresh air window 24 is in an open state; the third duct 13 is provided on each of the branch pipes 122.

[0040] Optionally, by adding a third air duct 13 and a fresh air window 24, when the dehumidifier 40 switches from the working state to the shutdown state, the start valve on the corresponding branch pipe 122 is closed to block the high-temperature air from the hot bending machine from being delivered to the dehumidifier 40. At the same time, the fresh air window 24 is switched to the open state to introduce fresh, cool air from outside the processing workshop into the dehumidifier 40 to cool the rotor 42 of the dehumidifier 40, so that the temperature of the regeneration air system of the dehumidifier 40 is within a suitable range. For example, when the regeneration air system of the dehumidifier 40 cools down to 50 degrees Celsius, and after receiving the shutdown command, the dehumidifier 40 runs for another 180 seconds before completely shutting down, thereby preventing the temperature of the dehumidifier 40 from running out of control.

[0041] Please see Figures 1 to 3 In some embodiments, the control component 30 includes a second control valve 32 located in the third air duct 13, and the second control valve 32 is used to control the fresh air window 24 to be in the open state or in the closed state.

[0042] Optionally, the second control valve 32 is also a pneumatic valve. By setting the second control valve 32 to control the opening and closing state of the fresh air window 24, the introduction of air can be automatically adjusted, thereby improving the intelligent management and energy efficiency of the system.

[0043] Please see Figures 3 to 4 In some embodiments, the dehumidifier 40 includes a main unit 41, a rotor 42, and a heater 43, and the air from the second air duct 12 passes sequentially through the heater 43 and the rotor 42.

[0044] Understandably, heater 43 can be used to heat the air supplied from the second air duct 12. Since the air in the second air duct 12 first absorbs the heat from the hot bending machine, heater 43 can use lower power to heat the air to the required temperature. For example, if the temperature of the air supplied from the hot bending machine is 80 degrees Celsius and the required air temperature is 90 degrees Celsius, heater 43 can then heat the air from 80 degrees Celsius to the required 90 degrees Celsius without heating the air from room temperature to 90 degrees Celsius. The heated air is then supplied to the rotor 42 to bake the rotor 42 and evaporate the water vapor on the rotor 42, ultimately reducing energy consumption and achieving the purpose of energy saving.

[0045] Please see Figures 2 to 4 In some embodiments, the duct assembly 10 further includes an exhaust duct 15, one end of which is connected to the dehumidifier 40 and the other end of which extends to the outside. The exhaust duct 15 is used to exhaust the air flowing through the impeller 42.

[0046] Optionally, the air transferred from the heater 43 to the rotor 42, after baking the rotor 42, is discharged to the outside of the processing workshop through the exhaust pipe 15, thereby avoiding affecting the processing environment of the processing workshop. By adding the exhaust pipe 15 to discharge the air flowing through the rotor 42 to the outside, the evaporated moisture can be effectively removed, preventing the moisture from flowing back and polluting the indoor environment.

[0047] Optionally, a fourth control valve 34 is provided on the exhaust duct 15.

[0048] Please see Figures 2 to 4 In some embodiments, the induced draft fan 20 is a centrifugal fan. The fresh air dehumidification equipment also includes a maintenance platform connected to the induced draft fan 20, through which the centrifugal fan can be maintained.

[0049] Optionally, the motor and impeller of the centrifugal fan can be made of high-temperature resistant alloys, stainless steel, or other materials, enabling it to withstand high-temperature gases up to 250°C. The volute structure of the centrifugal fan also helps to smoothly expel the high-temperature airflow, preventing localized heat buildup. The centrifugal fan's drive system (direct drive or belt drive) and rolling / sliding bearing system remain stable under long-term operation with lubrication and maintenance. Combined with its robust structure and good operational balance, it is less prone to vibration and fatigue damage, resulting in a long service life and easy maintenance in industrial applications.

[0050] Please see Figures 2 to 4 In some embodiments, the duct assembly 10 further includes an exhaust pipe 14, which is connected to the first duct 11. When the dehumidifier 40 is in operation, the exhaust pipe 14 is closed; when the dehumidifier 40 is in shutdown, air in the first duct 11 flows into the exhaust pipe 14.

[0051] Optionally, a third control valve 33 is provided on the exhaust pipe 14, and a fourth control valve 34 is provided on the exhaust pipe 15.

[0052] Optionally, by connecting the exhaust pipe 14 to the first air duct 11 and opening the exhaust pipe 14 to discharge air when the dehumidifier 40 stops, it is possible to avoid the accumulation of hot air causing excessive system pressure or energy waste. At the same time, it can be closed during operation so that the air in the first air duct 11 is concentrated and delivered to the dehumidifier 40, thereby improving the energy recovery rate and system flexibility.

[0053] Please see Figures 2 to 4 The working process of the fresh air dehumidification equipment is as follows:

[0054] First, when the dehumidifier 40 is in operation, the first control valves 31 and the pneumatic valves on the branch pipes 122 are opened, while the second control valve 32 and the third control valve 33 on the exhaust pipe 14 are closed. This allows the induced draft fan 20 to drive the hot air in the first duct 11 to the second duct 12, and then into the dehumidifier 40 through the second duct 12. The hot air then passes through the heater 43, which can provide auxiliary heating if the waste heat is insufficient, thereby providing energy for the moisture absorbed by the evaporator rotor 42. Finally, the air is discharged outdoors through the exhaust pipe 15.

[0055] If one dehumidifier 40 needs to be stopped for maintenance, close the pneumatic valve on the corresponding branch pipe 122 and open its corresponding second control valve 32 to allow outdoor air to be introduced into the rotor 42 of the dehumidifier 40 that needs maintenance through the fresh air window 24, so that the temperature of the rotor 42 does not exceed 50 degrees Celsius; while the pneumatic valve on the other branch pipe 122 remains open, that is, the other dehumidifier 40 can continue to work, ensuring that the processing workshop maintains a constant humidity environment.

[0056] Optionally, the first duct 11, the second duct 12, and the third duct 13 can all be made of galvanized material and fitted with insulation sleeves to prevent rust and reduce heat loss. The insulation sleeves can be made of rock wool with a thickness of 30mm.

[0057] Optionally, the operating power of heater 43 can be reduced by utilizing the waste heat from the hot bending machine; if the waste heat from the hot bending machine is sufficient, heater 43 can be completely shut off. By integrating the fresh air dehumidification equipment with the hot bending machine, the waste heat from the glass processing process can be fully utilized to replace or reduce the energy consumption of heater 43, while multiple dehumidifiers 40 can ensure continuous production and improve glass processing efficiency.

[0058] Please see Figures 2 to 4This utility model also proposes a glass processing system, which includes a fresh air dehumidification device. The specific structure of the fresh air dehumidification device is as described in the above embodiments. Since this glass processing system adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0059] In some embodiments, the glass processing system further includes a hot bending machine located at one end of the first air duct 11.

[0060] Optionally, the glass processing system uses simple electrical components to recover the high-temperature exhaust gas from the hot bending furnace and use it for the dehumidifier 40. Through simple operation, the hot bending machine and the existing dehumidifier 40 can be linked for control, making full use of the high-temperature exhaust gas from the hot bending furnace, reducing the amount of regenerative heating required by the dehumidifier 40, saving energy consumption, and at the same time protecting the rotor 42 from damage caused by high-temperature baking when the machine is stopped.

[0061] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
