[0051] Figure 1 This is a general schematic diagram of a demisting and air supply device for the connection area between the wet press section and the drying section of a paper machine according to an embodiment of the present invention; Figure 2 This is another schematic diagram of a demisting and air supply device for the connecting area between the wet press section and the drying section of a paper machine according to an embodiment of the present invention.
[0052] like Figure 1-Figure 2As shown, the demisting and air supply device for the connection area between the wet press section and the drying section of a paper machine according to an embodiment of the present invention comprises a first demisting box 11, a second demisting box 12, a first air supply box 21, a second air supply box 22, a demisting duct 31, and an air supply duct 32;
[0053] Among them, the first demister box 11 is installed on the first frame side panel 41 of the paper machine operating side OS, the first air supply box 21 is also installed on the first frame side panel 41 of the paper machine operating side OS, the second demister box 12 is installed on the second frame side panel 42 of the paper machine transmission side DS, and the second air supply box 22 is also installed on the second frame side panel 42 of the paper machine transmission side DS. The first demister box 11, the second demister box 12, the first air supply box 21, and the second air supply box 22 are all located above the paper machine dryer wire;
[0054] The first demister box 11 and the second demister box 12 are each provided with a plurality of mist extraction ports for removing mist from the connecting area between the wet press section and the drying section of the paper machine. The first air supply box 21 and the second air supply box 22 are each provided with a plurality of air supply ports for blowing hot air to the connecting area between the wet press section and the drying section of the paper machine.
[0055] The demisting duct 31 is used to connect the first demisting box 11 and the second demisting box 12 to the demisting fan duct of the wet pressing section, and the air supply duct 32 is used to connect the first air supply box 21 and the second air supply box 22 to the air supply fan duct of the drying section.
[0056] According to the above technical solution, the demisting and air supply device for the connection area between the wet pressing section and the drying section of the paper machine of the utility model can achieve the following beneficial technical effects: solving the condensation and dripping problem in the connection area between the wet pressing section and the drying section of the paper machine, saving energy and reducing operating costs.
[0057] Specifically, the demisting duct 31 connects the first demisting box 11 and the second demisting box 12 to the wet press section demisting fan duct, thereby extracting the fog in the connection area between the wet press section and the drying section of the paper machine through the demisting port, reducing or even removing the fog or moisture in the area; the air supply duct 32 connects the first air supply box 21 and the second air supply box 22 to the drying section air supply fan duct, thereby blowing hot air to the connection area between the wet press section and the drying section of the paper machine through the air supply port, raising the overall temperature of the area, especially the temperature at the ceiling of the frame, thereby reducing or even avoiding the condensation and dripping problem in the connection area between the wet press section and the drying section of the paper machine. Moreover, directly connecting to the existing wet press section demisting fan duct through the demisting duct 31 and directly connecting to the existing drying section air supply fan duct through the air supply duct 32 will not increase new operating costs, save energy (no additional compressed air is required), and reduce operating costs compared to the existing technology.
[0058] In some embodiments, as Figure 1-Figure 2As shown, the first demister box 11 is located below the first air supply box 21, and the second demister box 12 is located below the second air supply box 22. According to the above technical solution, the demister air supply device for the connection area between the wet press section and the drying section of the paper machine of the present invention can achieve the following beneficial technical effects: the demister air supply effect is better, thereby better solving the condensation and dripping problem in the connection area between the wet press section and the drying section of the paper machine. Specifically, since hot air (hot air) is lighter and easier to rise, and cold air (such as fog or water vapor) is heavier and easier to fall, the demister box is arranged below the air supply box, which can better perform demisting. The air supply box is closer to the frame ceiling, and can also better increase the temperature at the frame ceiling, thereby better solving the condensation and dripping problem in the connection area between the wet press section and the drying section of the paper machine.
[0059] In some embodiments, as Figure 1-Figure 2 As shown, the first demister box 11 and the first air supply box 21 form a first integrated demister air supply box, which is separated by a first partition plate 51 in the middle of the box body; the second demister box 12 and the second air supply box 22 form a second integrated demister air supply box, which is separated by a second partition plate 52 in the middle of the box body. According to the above technical solution, the demister air supply device for the connection area between the wet press section and the drying section of the paper machine of the present invention can achieve the following beneficial technical effects: the design of the demister air supply device box body is simple and effective, and can reduce operating costs while ensuring that the condensation and dripping problem in the connection area between the wet press section and the drying section of the paper machine is solved. Specifically, the two boxes (demister box and air supply box) are integrated into one box body, which makes the box body design simpler, saves the box body manufacturing cost, and does not affect the solution to the condensation and dripping problem in the connection area between the wet press section and the drying section of the paper machine.
[0060] In some embodiments, as Figure 1-Figure 2 As shown, the boxes of the demisting boxes (first demisting box 11, second demisting box 12) and the air supply boxes (first air supply box 21, second air supply box 22) can be made of metal plates, and the first partition plate 51 and the second partition plate 52 can also be made of metal plates. For example, the metal plates can be specifically made of stainless steel plates.
[0061] In some embodiments, as Figure 1-Figure 2As shown, the mist extraction direction of the multiple mist extraction ports is parallel to the frame ceiling, and the air supply direction of the multiple air supply ports is parallel to the frame ceiling. According to the above technical solution, the demisting and air supply device for the connection area between the wet press section and the drying section of the paper machine of the present invention can achieve the following beneficial technical effects: the demisting and air supply effect is better, thereby better solving the condensation and dripping problem in the connection area between the wet press section and the drying section of the paper machine. That is, the demisting port of the first demisting box 11 on the operating side of the paper machine is along the transverse direction (CD direction) of the paper machine toward the paper machine transmission side, and the air supply port of the first air supply box 21 on the operating side of the paper machine is also along the transverse direction of the paper machine toward the paper machine transmission side; the demisting port of the second demisting box 12 on the transmission side of the paper machine is along the transverse direction of the paper machine toward the paper machine operating side, and the air supply port of the second air supply box 22 on the transmission side of the paper machine is also along the transverse direction of the paper machine toward the paper machine operating side. In this way, mist and / or hot air can flow better in the connection area between the wet press section and the drying section of the paper machine, and the demisting and air supply effect is better, thereby better solving the condensation and dripping problem in the connection area between the wet press section and the drying section of the paper machine.
[0062] It should be noted that, although it is preferred that the mist extraction direction of the multiple mist extraction ports is parallel to the rack ceiling, and the air supply direction of the multiple air supply ports is parallel to the rack ceiling, this parallelism may not be absolutely parallel, but may be tilted up and down by 10 degrees, for example, and still achieve a good demisting and air supply effect, thereby solving the condensation and dripping problem in the connection area between the wet press section and the drying section of the paper machine.
[0063] In some embodiments, as Figure 1-Figure 2 As shown, the demisting and air supply device for the connection area between the wet press section and the drying section of a paper machine further includes a demisting valve 61 and an air supply valve 62.

[0064] In some embodiments, as Figure 1-Figure 2 As shown, the demisting and air supply device for the connection area between the wet press section and the drying section of a paper machine further includes a hygrometer 71 and a thermometer 72. The hygrometer 71 is disposed on the demisting duct 31, and the thermometer 72 is disposed on the air supply duct 32. According to the above technical solution, the demisting and air supply device for the connection area between the wet press section and the drying section of a paper machine of the present invention can achieve the following beneficial technical effects: it can better control the demisting amount and air supply amount according to humidity and temperature, thereby better solving the problem of condensation and dripping in the connection area between the wet press section and the drying section of the paper machine.
[0065] In some embodiments, as Figure 1-Figure 2As shown, when the humidity measured by hygrometer 71 is less than or equal to 30%, the opening of demisting valve 61 is adjusted from 100% to 60%. According to the above technical solution, the demisting and air supply device for the connection area between the wet press section and the drying section of a paper machine of the present invention can achieve the following beneficial technical effects: after the humidity reaches the standard, the operating cost can be further reduced by reducing the opening of the demisting valve.
[0066] In some embodiments, as Figure 1-Figure 2 As shown, when the temperature measured by thermometer 72 is greater than or equal to 80 degrees Celsius, the opening of air supply valve 62 is adjusted from 100% to 50%. According to the above technical solution, the demisting and air supply device for the connection area between the wet press section and the drying section of a paper machine of the present invention can achieve the following beneficial technical effects: after the temperature reaches the standard, the operating cost can be further reduced by reducing the opening of the air supply valve.
[0067] In some embodiments, as Figure 1-Figure 2 As shown, the humidity data measured by the hygrometer 71 and the temperature data measured by the thermometer 72 can be displayed online on the distributed control system screen so as to monitor the humidity and temperature in time and adjust the opening of the defogger valve 61 and / or the air supply valve 62 in time.
[0068] In some embodiments, as Figure 1-Figure 2 As shown, the first demister box 11 and the second demister box 12 are connected, and the first air supply box 21 and the second air supply box 22 are also connected. According to the above technical solution, the demisting and air supply device for the connection area between the wet press section and the drying section of a paper machine of the present invention can achieve the following beneficial technical effects: only a single demisting duct is required to connect the connected first and second demister boxes to the wet press section demisting fan duct, and only a single air supply duct is required to connect the connected first and second air supply boxes to the drying section air supply fan duct, thereby shortening the length of the demisting duct and the air supply duct, and reducing the construction cost of the device.
[0069] In some embodiments, as Figure 1-Figure 2 As shown, multiple mist extraction ports are evenly spaced along the machine's longitudinal direction (MD), and multiple air supply ports are evenly spaced along the machine's longitudinal direction. According to the above technical solution, the demisting and air supply device for the connection area between the wet press section and the dryer section of a paper machine of the present invention can achieve the following beneficial technical effects: the multiple mist extraction ports and air supply ports evenly cover the longitudinal space between the wet press section and the dryer section of the paper machine, improving the demisting and air supply effect, thereby better solving the problem of condensation and dripping in the connection area between the wet press section and the dryer section of the paper machine.

[0070] In some embodiments, as Figure 1-Figure 2As shown, multiple mist extraction ports and multiple air supply ports are vertically staggered. Based on the above technical solution, the demisting and air supply device for the connection area between the wet press section and the dryer section of a paper machine can achieve the following beneficial technical effects: it reduces the mutual influence between the mist extraction ports and the air supply ports, thereby better solving the problem of condensation and dripping in the connection area between the wet press section and the dryer section of the paper machine. For example, each mist extraction port can be located between two adjacent air supply ports, and each air supply port can be located between two adjacent mist extraction ports.
[0071] The operation mode of the demisting and air supply device for the connection area between the wet press section and the drying section of a paper machine according to an embodiment of the utility model can be as follows:
[0072] When the paper machine is just started, the air temperature in the frame ceiling area of the connection area between the wet press section and the drying section of the paper machine is low, the moisture is large, and condensation is easy to occur. At this time, the defogger valve 61 is opened (opening degree 100%), and since the defogger pipe 31 connects the first defogger box 11 and the second defogger box 12 to the wet press section defogger fan pipe, the mist in the connection area between the wet press section and the drying section of the paper machine is extracted through the mist extraction port, reducing or even removing the mist or moisture in the area; the air supply valve 62 is opened (opening degree 100%), and since the air supply pipe 32 connects the first air supply box 21 and the second air supply box 22 to the dryer section air supply fan pipe, hot air is blown to the connection area between the wet press section and the drying section of the paper machine through the air supply port, raising the overall temperature of the area, especially the temperature at the frame ceiling, thereby reducing or even avoiding the condensation and dripping problem in the connection area between the wet press section and the drying section of the paper machine.
[0073] When the humidity measured by the hygrometer 71 is lower than or equal to 30%, the opening of the defogger valve 61 can be adjusted from 100% to 60%.
[0074] When the temperature measured by the thermometer 72 is higher than or equal to 80 degrees Celsius, the opening of the air supply valve 62 can be adjusted from 100% to 50%.
[0075] The above describes the specific implementation methods of the present invention, but those skilled in the art will understand that the above specific implementation methods do not constitute a limitation of the present invention. Those skilled in the art can make various modifications based on the above disclosure without exceeding the scope of the present invention.
