[0022] like Figure 1-3 As shown in the embodiment, a heat cascade utilization device for workshop temperature and humidity control includes a workshop 10. An oil storage tank 11, a boiler 12, and an oven 13 are sequentially connected outside the workshop 10. A film is conveyed from the workshop 10 to the oven 13 and then rolled back into the workshop 10. The characteristic feature is that a steam generating device 14 is provided between the boiler 12 and the oven 13. The steam generating device 14 includes a steam heat exchange pipe 142 and a heat exchange chamber 141. The heat exchange chamber 141 is connected to both the boiler 12 and the oven 13. The steam heat exchange pipe 142 is connected to the workshop 10 through a steam pipe 15.
[0023] The steam generating device 14 is set up, and heat exchange chamber 141 and steam heat exchange pipe 142 are respectively filled with heat transfer oil and water. The high-temperature heat transfer oil heated by boiler 12 exchanges heat with water in the steam generating device 14. The water in the steam heat exchange pipe 142 is heated and boiled by high-temperature heat transfer oil to form steam and is discharged into workshop 10 along steam pipe 15 to regulate the temperature and humidity of workshop 10.
[0024] In this embodiment, the oil storage tank 11, the boiler 12, and the oven 13 are connected by a pipeline. The oil storage tank 11 stores heat transfer oil, which is then transported from the oil storage tank 11 to the boiler 12. After being heated by the boiler 12, the heat transfer oil is transported to the oven 13 to provide heat to the oven 13 and raise its temperature. After completing the heat exchange in the oven 13, the heat transfer oil cools down and returns to the oil storage tank 11, thus realizing a heat transfer oil circulation loop.
[0025] The oven 13 is equipped with a heat transfer oil pipe, and the heat transfer oil is delivered to the heat transfer oil pipe inside the oven 13 to heat up the oven 13.
[0026] Furthermore, workshop 10 is equipped with coating, cutting, and pressing units to process the film. The temperature and humidity within workshop 10 are critical during coating, cutting, and pressing processes; suitable temperature and humidity are beneficial to the quality and performance of the film processing. Further, the film is conveyed from the coating unit to the drying oven 13, where it is cured before returning to the pressing unit within workshop 10 for pressing and then wound up to the winding unit.
[0027] like Figure 2-3 As shown, in another preferred embodiment, the heat exchange chamber 141 is provided with a first liquid inlet 145 and a first liquid outlet 146; the first liquid inlet 145 is connected to the boiler 12, the first liquid outlet 146 is connected to the oven 13, and the first liquid outlet 146 is provided on the side wall of the steam generating device 14 near the top.
[0028] The position of the first outlet 146 is set to ensure that the heat transfer oil entering the heat exchange chamber 141 covers the steam heat exchange tube 142 with the largest possible area, thereby increasing the heat exchange area, improving the heat exchange effect, and increasing the steam flow rate formed by the water in the steam heat exchange tube 142.
[0029] like Figure 2-3 As shown, the steam heat exchanger tube 142 is provided with a second liquid inlet 147 and a second liquid outlet 148; the second liquid inlet 147 is connected to the steam trap 20 through the condensate pipe 21, and the second liquid outlet 148 is connected to the workshop 10 through the steam pipe 15.
[0030] Furthermore, such as Figure 1 and Figure 3As shown, one end of the condensate pipe 21 is connected to the steam trap 20, and the other end is connected to the steam heat exchanger 142 of the steam generating device 14 and extends to the bottom of the steam heat exchanger 142 to avoid interference with the steam output above the steam heat exchanger 142.
[0031] like Figure 1 As shown, in another preferred embodiment, two branches are connected in parallel between the boiler 12 and the oven 13. One of the two branches is equipped with a first valve 16, and the other is equipped with a second valve 17 and a steam generating device 14. The second valve 17 is located at the liquid inlet end of the steam generating device 14.
[0032] Two branches are connected in parallel, with the branch equipped with the first valve 16 serving as a backup branch to improve pipeline safety.
[0033] In this embodiment, both the first valve 16 and the second valve 17 are shut-off valves.
[0034] Specifically, when the temperature and humidity inside workshop 10 are suitable and steam is not needed to regulate the temperature and humidity inside workshop 10, the steam pipeline is closed and no longer supplies steam to workshop 10; therefore, the backup branch is activated (i.e., the first valve 16 is opened) and the branch where the steam generating device 14 is located is closed (i.e., the second valve 17 is closed) so that the steam generating device 14 no longer generates new steam to increase the pressure of the steam pipeline.
[0035] Furthermore, a first oil pump 18 is installed between the boiler 12 and the branch; a second oil pump 19 is also installed on the branch where the steam generating device 14 is located, and the second oil pump 19 is located at the liquid outlet end of the steam generating device 14.
[0036] The first oil pump 18 and the second oil pump 19 are used to pressurize and transport the heat transfer oil in the pipeline.
[0037] Furthermore, a check valve 24 is provided between the second oil pump 19 and the oven 13.
[0038] The one-way valve 24 is designed to prevent the heat transfer oil in the oven 13 from flowing back into the steam generating device 14.
[0039] like Figure 1-3 As shown, in another preferred embodiment, a steam trap 20 is provided on the steam pipe 15, and the steam trap 20 is connected to the steam heat exchange pipe 142 through the condensate pipe 21.
[0040] As steam flows in the steam pipe 15, it condenses upon contact with the condenser due to the temperature of the pipe wall. This means that some of the steam will form water. The condensed water is then recovered through the steam trap 20 into the steam heat exchange tube 142 of the steam generating device 14, which helps to save water resources and improve system efficiency.
[0041] Furthermore, a third valve 28 is provided on the steam pipe 15, which is located between the steam trap 20 and the steam generating device 14.
[0042] The third valve 28 is a shut-off valve. The opening and closing of the third valve 28 is used to control whether steam enters workshop 10.
[0043] Furthermore, a water storage tank 25 and a shut-off valve are installed on the condensate pipe 21; the shut-off valve is located between the water storage tank 25 and the steam heat exchange pipe 142.
[0044] The water storage tank 25 recovers and stores the condensate in the steam pipe 15, and the shut-off valve controls whether water is supplied to the steam generating device 14.
[0045] like Figure 2-3 As shown, in another preferred embodiment, a pressure valve 22 is provided on the steam generating device 14.
[0046] The steam generating device 14 includes a tank body 144 and a tank cover 143. The tank body 144 includes a heat exchange chamber 141, and a steam heat exchange pipe 142 is formed between the tank body 144 and the tank cover 143.
[0047] Pressure valve 22 is located on tank cover 143 or at the second liquid outlet 148.
[0048] The pressure valve 22 is designed to ensure the safety of the steam generating device 14 and the pipeline. When the pressure inside the steam generating device 14 is too high, the pressure valve 22 will be automatically opened to release the gas.
[0049] like Figure 1 As shown, in another preferred embodiment, a spraying device 23 is provided in the workshop 10; the spraying device 23 is connected to the steam pipe 15.
[0050] The spray device 23 includes pipelines and multiple spray heads 231; the installation of the spray device 23 expands the coverage of steam on the workshop 10.
[0051] like Figure 1 As shown, in another preferred embodiment, a temperature and humidity sensor 26 and a temperature and humidity display are provided in the workshop 10. The temperature and humidity sensor 26 is used to detect the temperature in the workshop 10 in real time and transmit it to the temperature and humidity display for digital display. The temperature and humidity sensor 26 is connected to the first valve 16, the second valve 17 and the third valve 28 through the temperature and humidity controller 27 to control the opening and closing of the first valve 16, the second valve 17 and the third valve 28.
[0052] Specifically, the temperature and humidity sensor 26 is a DHT series or SHT series; the temperature and humidity display is an LCD display or an OLED display; and the temperature and humidity controller 27 is a PLC.
[0053] The valve can be automatically opened and closed by setting the temperature and humidity sensor 26, the temperature and humidity controller 27 and the temperature and humidity display.
[0054] like Figure 1-3 As shown, this utility model has two states during use:
[0055] In the first state, the temperature and humidity of workshop 10 are suitable, and there is no need to introduce steam. At this time, open the first valve 16 and close the second valve 17 and the third valve 28.
[0056] In the second state, the temperature and humidity of workshop 10 need to be regulated by steam. At this time, the first valve 16 is closed and the second valve 17 and the third valve 28 are opened.
[0057] In the first state, only the circulation loop of the heat transfer oil is involved. The heat transfer oil is stored in the oil storage tank 11, passes through the boiler 12, the first valve 16 and the oven 13 in sequence, and finally returns to the oil storage tank 11.
[0058] In the second state, there are heat transfer oil circuit, steam flow path and condensate flow path. The heat transfer oil circuit starts from the oil storage tank 11 and passes through the boiler 12, steam generating device 14 and oven 13 in sequence, and finally returns to the oil storage tank 11. The steam flow path starts from the steam generating device 14 and passes through the steam trap 20 to the workshop 10. The condensate flow path starts from the steam trap 20 to the steam generating device 14.
[0059] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
