DETAILED DESCRIPTION

[0034] Hereinafter, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present disclosure. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0035] In the related art, the chemical fiber industry uses a composite air conditioning unit to deliver process air and ambient air to the site due to the requirements of the spinning process. The process air is mainly provided to the fiber cooling device, and the ambient air is mainly used to cool the overall environment of the spinning workshop. The fiber cooling device has high requirements for the air conditioning air, mainly in terms of the temperature of the air conditioning air. The temperature of the air conditioning air directly affects the cooling and crystallization effect of the fiber after being sprayed from the box. At the same time, the fiber will have a certain static electricity after being cooled by air friction, so the air conditioning air has a certain humidity. Some composite air conditioners change the air through the process air blower and the ambient air blower to the humidifying device for humidification. Since the air volume requirements of the fiber cooling device and the on-site ambient air may be different, and the overall spinning device has multiple floors and a large area, it is difficult to make the on-site ambient humidity meet certain requirements by only using the ambient air blower of the composite air conditioner to deliver air to the site. At the same time, with the continuous development and progress of the equipment and process of the chemical fiber industry, the continuous development and production of some porous, fine denier, and special functional fibers have higher requirements for the on-site ambient humidity. In some scenarios, special humidifying equipment is added to the site to meet the on-site humidity requirements, but this increases the cost. Therefore, how to balance the cost and meet the on-site ambient humidity requirements is a problem that needs to be solved.

[0036] To overcome the above problems, the embodiment provides a humidity control device, a field spraying device is added in the composite air conditioning unit, when the humidity of the process field needs to be adjusted, the amount of liquid sprayed to the process field by the first spraying head can be controlled through the control of the electric valve, so as to adjust the humidity of the process field, which is beneficial to meet the humidity demand of the process field. The flexibility of the humidity control device of the embodiment is higher, and a humidifying device specially added for humidifying the process field is not needed.

[0037] The humidity adjusting device provided by the embodiment will be illustrated below with reference to the accompanying drawings.

[0038] Figure 1 A structural schematic diagram of a humidity adjusting device according to an embodiment of the present disclosure is shown; Figure 2 A structural block diagram of a humidity control device according to an embodiment of the present disclosure is shown. As Figure 1 and Figure 2 shown, the humidity adjusting device comprises: an air inlet device 100; a humidifying device 200 connected to the output end of the air inlet device 100, used for humidifying the air provided by the air inlet device 100; a process air supply device 300 and an environment air supply device 400, respectively connected with the humidifying device 200; the process air supply device 300 is used for discharging the humidified air to the cooling device of the process equipment; the environment air supply device 400 is used for discharging the humidified air to the process field; a field spraying device 500, having a first conveying pipeline 501, an electric valve 502 and a plurality of first spraying heads; the first conveying pipeline 501 is used for conveying liquid to the first spraying head; the first spraying head is used for spraying liquid to the process field; the electric valve 502 is used for controlling the flow of the first conveying pipeline 501; a liquid storage device 600, having a first liquid inlet, a second liquid inlet and a liquid outlet; the liquid outlet sends liquid to the humidifying device 200 through a second conveying pipeline; the first liquid inlet is connected with a liquid source; the second liquid inlet is connected with the first conveying pipeline 501 through a recovery pipeline, so as to recover the liquid in the field spraying device 500; a pressure detection member 701, a variable frequency circulating pump 702 and a first controller 703, the pressure detection member 701 and the variable frequency circulating pump 702 are respectively electrically connected with the first controller 703; the pressure detection member 701 is used for detecting the pressure of the first conveying pipeline 501; the variable frequency circulating pump 702 is connected between the liquid storage device 600 and the humidifying device 200.

[0039] The air inlet device 100 is used for providing air for the humidity control device. In some examples, the air inlet device 100 comprises: a return air passage 110, a fresh air passage 120, a first fan 130, a first filtering sub-device 140 and a temperature adjusting sub-device 150; wherein the first fan 130 is used for conveying the return air of the return air passage 110 and the fresh air of the fresh air passage 120 to the first filtering sub-device 140 for filtering, and conveying the filtered air to the temperature adjusting sub-device 150 for temperature adjustment.

[0040] Specifically, the air inlet device 100 has a mixing chamber, the mixing chamber is provided with the first fan 130, and the mixing chamber has a fresh air outlet and a return air outlet. The fresh air outlet and the return air outlet can be located at different sides of the mixing chamber, for example, the fresh air outlet and the return air outlet are located at two adjacent sides of the mixing chamber, and the return air outlet can be located at a side of the mixing chamber away from the output end. In addition, the mixing chamber can also have an exhaust air outlet connected with an exhaust air pipeline to form an exhaust air passage 160 for discharging air in the humidity control device; the exhaust air outlet can be located at the same side as the fresh air outlet. Optionally, the return air outlet, the fresh air outlet and the exhaust air outlet are respectively provided with control valves to control the opening or closing of the corresponding air outlets. In other examples, the air inlet device 100 can also not be provided with the return air passage 110.

[0041] The fresh air outlet is connected with a fresh air pipeline to form a fresh air passage 120 for air outside the process site to enter the humidity control device. The return air outlet is connected with a return air pipeline to form a return air passage 110 for air in the process site to flow back to the humidity control device.

[0042] The first filtering sub-device 140 can include a coarse filter for removing a small amount of solid particle impurities in the air. The first filtering sub-device 140 can be arranged at a side of the first fan 130 away from the return air outlet, and a preset interval can be provided between the first filtering sub-device 140 and the first fan 130. In other examples, the temperature adjusting sub-device 150 can also be arranged at the output end of the humidifying device 200.

[0043] A temperature adjusting sub-device 150 can be arranged at a side of the first filtering sub-device 140 away from the first fan 130, and the temperature adjusting sub-device 150 is used for heating or cooling the filtered air, which can be arranged according to actual needs. The temperature adjusting sub-device 150 can include a heat exchanger, which can be a surface cooler (also known as a surface cooler).

[0044] The air after filtering and temperature adjustment enters the humidifying device 200 for humidification. The humidifying device 200 can use a spray humidification method to humidify the entering air. The humidifying device 200 can specifically include a humidifying chamber and a plurality of second spray heads, the plurality of second spray heads are used for atomizing liquid delivered by a second delivery pipeline and spraying the liquid into the mixing chamber, so that the liquid can be fully mixed with the air in the mixing chamber.

[0045] Optionally, in order to improve the mixing effect of the liquid and the wind, the second conveying pipeline can comprise a first guide section, a first liquid outlet section extending from top to bottom, a second guide section, and a second liquid outlet section extending from bottom to top; the first guide section is used to guide the liquid to the first liquid outlet section; the liquid flows from top to bottom in the first liquid outlet section, part of the liquid is sprayed from the plurality of second spray heads connected with the first liquid outlet section, and the other part of the liquid flows to the second guide section and continues to flow to the second liquid outlet section; the liquid flows from bottom to top in the second liquid outlet section, part of the liquid is sprayed from the second spray heads connected with the second liquid outlet section, and the other part of the liquid will be conveyed to the first spray heads by the first conveying pipeline 501. The number of the above-mentioned first liquid outlet section and the second liquid outlet section can be set according to actual needs, and the number of the first guide section and the second guide section can also be set according to actual needs.

[0046] Optionally, the liquid outlet section of the second liquid outlet section can be connected with a three-way joint, so that part of the liquid flowing out of the second liquid outlet section can be conveyed to the first spray heads through the first conveying pipeline 501, and the other part of the liquid can be conveyed to the first liquid outlet section to continue to humidify the wind entering the humidifying bin. Alternatively, the liquid outlet section of the second liquid outlet section can be connected with a three-way joint, and the two outlets of the three-way joint can also be connected with two first conveying pipelines 501 respectively, and the two first conveying pipelines 501 can correspond to different workshop sites respectively.

[0047] It can be understood that: the setting position and arrangement mode of the second spray heads can be set according to actual needs. The specific structure of the second conveying pipeline can be set according to actual needs. The specific structure of the humidifying device 200 is not limited to this and can be set according to actual needs.

[0048] The process air supply device 300 and the environmental air supply device 400 can be connected with the side of the humidifying device 200 away from the air inlet device 100. The process air supply device 300 and the environmental air supply device 400 can be two relatively independent channels.

[0049] The electric valve 502 is arranged in the first conveying pipeline 501 of the on-site spraying device 500, and is used to control the flow of the fluid in the first conveying pipeline 501. For example, when the demand for humidity in the process site is large, the opening degree of the electric valve 502 is increased; when the demand for humidity in the process site is small, the opening degree of the electric valve 502 can be reduced; when the wind output from the environmental air supply device 400 meets the humidity demand of the process site, the electric valve 502 can be closed, and the on-site spraying device 500 stops spraying liquid to the process site.

[0050] The layout and number of the first conveying pipeline 501 can be set according to actual needs. For example, when there are multiple floors in the application site, the liquid can be guided into the first conveying pipeline 501 corresponding to each floor through a tee joint. When there are multiple workshop sites in a floor, the liquid can also be guided into the first conveying pipeline 501 corresponding to each workshop site through a tee joint. Of course, the first conveying pipeline 501 can have one, which can be arranged along the distribution of the workshop site.

[0051] The process site of each workshop is respectively provided with a first spray head corresponding thereto. The layout position and number of the first spray head can be set according to actual needs, which are not limited in the embodiment.

[0052] The liquid storage device 600 can obtain liquid from a liquid source such as a public liquid system, or can recover liquid from the pipeline conveying the liquid in the humidity control equipment, which can not only ensure that the liquid can meet the demand, but also save liquid resources.

[0053] Since the liquid supplied to the spray device 500 in the site will change in pressure and flow when the electric valve 502 is opened or the opening degree is adjusted, and the pressure and flow of the liquid supplied to the humidifying device 200 will also change, thereby affecting the humidifying effect of the humidifying device 200. Therefore, a pressure detection member 701 can be arranged in the first conveying pipeline 501, which is used to detect the pressure of the first conveying pipeline 501; wherein the pressure detection member 701 can include a pressure sensor. The first controller 703 determines whether pressure fluctuation occurs according to the detection result of the pressure detection member 701, and if it is determined that pressure fluctuation occurs, the frequency of the variable frequency circulating pump 702 is adjusted until the detection result of the pressure detection member 701 tends to be stable, so that the humidifying device 200 is not affected when the spray device 500 in the site works, and the reliability of the humidity control equipment is ensured. Wherein the first controller 703 can adopt a DCS (Distributed Control System) or other electronic components with control function.

[0054] Specifically, when the opening degree of the electric valve 502 increases, the pressure detected by the pressure detection member 701 will increase and start to fluctuate, and the corresponding pressure of the humidifying device 200 will decrease and fluctuate accordingly, then the frequency of the variable frequency circulating pump 702 can be increased by the first controller 703 to make the pressure detected by the pressure detection member 701 tend to be stable.

[0055] Optionally, the pressure detection member 701 is located on the side of the electric valve 502 facing the humidifying device 200;

[0056] The interface of the first conveying pipeline 501 connected with the recovery pipeline is located between the pressure detection member 701 and the electric valve 502.

[0057] In some scenarios, when it is required to increase the humidity of the process site, the liquid provided by the liquid storage device 600 can be partially allowed to enter the process site through the first spraying head by controlling the electric valve 502 to be opened, or the liquid sprayed to the process site through the first spraying head can be increased by controlling the opening degree of the electric valve 502 to be increased, so as to increase the humidity of the process site and meet the humidity requirement of the process site.

[0058] The humidity control device provided by the embodiment can control the amount of liquid sprayed to the process site by the first spraying head by controlling the opening degree of the electric valve 502 when it is required to adjust the humidity of the process site, so as to adjust the humidity of the process site and meet the humidity requirement of the process site. The humidity control device has high flexibility and relatively low cost. In addition, the pressure detection member 701 is arranged in the first conveying pipeline 501, the variable frequency circulating pump 702 is arranged between the liquid storage device 600 and the humidifying device 200, and the first controller 703 electrically connected with the pressure detection member 701 and the variable frequency circulating pump 702 is arranged. The working reliability of the humidifying device 200 can be ensured while the on-site spraying device 500 works, so as to ensure the working reliability of the humidity control device.

[0059] As shown in FIGS. Figure 1 and Figure 3 In some embodiments, the on-site spraying device 500 further comprises: a second controller 704 electrically connected with the electric valve 502; a humidity sensor 705 and / or a timer 706 electrically connected with the second controller 704; wherein the humidity sensor 705 is used to detect the humidity of the process site; and the timer 706 is used to record the working time length of the on-site spraying device. The second controller 704 can be a DCS or other electronic components with control function.

[0060] In some examples, the on-site spraying device 500 further comprises: a second controller 704 and a humidity sensor 705, the humidity sensor 705 and the electric valve 502 are electrically connected with the second controller 704, and the second controller 704 controls the opening degree of the electric valve 502 according to the detection result of the humidity sensor 705. For example, when the second controller 704 determines that the current humidity of the process site is lower than the target humidity according to the detection result of the humidity sensor 705, the second controller 704 controls the electric valve 502 to be opened or controls the opening degree of the electric valve 502 to be increased; when the second controller 704 determines that the current humidity of the process site reaches the target humidity according to the detection result of the humidity sensor 705, the second controller 704 controls the electric valve 502 to be closed or controls the opening degree of the electric valve 502 to be decreased.

[0061] In some examples, the field spraying device 500 further comprises a second controller 704 and a timer 706, the timer 706 and the electric valve 502 are electrically connected with the second controller 704, the second controller 704 can control the electric valve 502 to open when the timer 706 starts timing, and control the electric valve 502 to close when the timer 706 finishes timing.

[0062] In some examples, the field spraying device 500 further comprises a second controller 704, a humidity sensor 705 and a counter, the humidity sensor 705, the timer 706 and the electric valve 502 are electrically connected with the second controller 704. In the implementation process, the second controller 704 controls the electric valve 502 to open when the timer 706 starts timing, and controls the electric valve 502 to close when the timer 706 finishes timing. During the timing of the timer 706, the second controller 704 can control the opening degree of the electric valve 502 according to the detection result of the humidity sensor 705.

[0063] In the embodiment, the above setting can realize the automatic control of the humidity of the process field. In addition, the first controller 703 is used to realize the pressure control, and the second controller 704 is used to realize the humidity control in the embodiment, and the two controls are relatively independent, which is beneficial to ensure the reliable operation of the humidity control device and the field spraying device 500.

[0064] In other embodiments, the electric valve 502 can also be electrically connected with the first controller 703, and the first controller 703 is used to control the electric valve 502 to open for a preset time length every interval of a preset time period.

[0065] In some embodiments, the humidity control device further comprises a check valve 640 connected in the recovery pipeline, which is used to block the liquid in the liquid storage device 600 from flowing to the first spraying head through the recovery pipeline, so as to ensure the working reliability of the field spraying device 500.

[0066] In some examples, the humidity control device further comprises a bypass pipeline and a bypass valve 650, two ends of the bypass pipeline are respectively communicated with the recovery pipeline, and the bypass valve 650 is installed in the bypass pipeline. The bypass valve 650 can be a manually operated valve, and the opening degree of the bypass valve 650 can be manually adjusted according to the actual situation to adjust the pressure of the humidity control device, so as to ensure the pressure stability of the liquid circulation and the stable operation of the whole humidity control device. In addition, when the check valve 640 fails, the liquid in the conveying pipeline can also be recovered to the liquid storage device 600 through the corresponding pipeline of the bypass valve 650.

[0067] In some embodiments, the liquid storage device 600 comprises a liquid storage tank 610, a filter combination net 620 and a floating ball valve 630; the filter combination net 620 is installed in the liquid storage tank 610 and divides the space in the liquid storage tank 610 into a first sub-space 611 and a second sub-space 612; the first sub-space 611 is located on the side of the filter combination net 620 facing the liquid outlet; the second sub-space 612 is located on the side of the filter combination net 620 facing away from the liquid outlet, so that the filter combination net 620 can filter the liquid flowing from the second sub-space 612 to the liquid outlet; the first sub-space 611 is in communication with the second liquid inlet; the second sub-space 612 is in communication with the first liquid inlet, and the first liquid inlet is arranged close to the top end of the second sub-space 612.

[0068] The filter combination net 620 is used to filter impurities in the liquid. The filter combination net 620 can comprise a plurality of layers of filter nets. In the plurality of layers of filter nets, the sizes of the filter holes in at least two layers of filter nets can be different. Alternatively, the sizes of the filter holes in each layer of filter nets in the plurality of layers of filter nets are the same. The filter combination net 620 can divide the liquid storage space in the liquid storage tank 610 into the first sub-space 611 and the second sub-space 612, and the volume of the second sub-space 612 is greater than that of the first sub-space 611, for example, the volume of the second sub-space 612 can be twice or three times that of the first sub-space 611. The first sub-space 611 is in communication with the second liquid inlet and the liquid outlet, so that the liquid in the recovery pipeline can enter the first sub-space 611 and then flow out of the liquid outlet; the second sub-space 612 is connected with the first liquid inlet, so that the liquid provided by the liquid source needs to pass through the filter combination net 620 for filtration before entering the first sub-space 611 and then flowing out of the liquid outlet.

[0069] The first liquid inlet is arranged close to the top end of the second sub-space 612, so that relatively more liquid can be stored in the liquid storage tank 610. For example, the liquid storage tank 610 can be in the form of a box, the side wall of the liquid storage tank 610 facing the second conveying pipeline is provided with a liquid outlet, and the liquid outlet is arranged close to the lower edge of the side wall; the top wall of the liquid storage tank 610 is provided with a second liquid inlet, and the second liquid inlet is arranged close to the edge of the top wall facing away from the second sub-space 612; the side wall of the liquid storage tank 610 facing away from the liquid outlet is provided with a first liquid inlet, and the first liquid inlet can be arranged close to the upper edge of the side wall. In other examples, the liquid outlet and the first liquid inlet can also be located on two adjacent side walls of the liquid storage tank 610.

[0070] In some examples, the liquid storage device 600 further comprises a float valve 630 for blocking the communication between the liquid storage tank 610 and the liquid source when the liquid level in the liquid storage tank 610 reaches a target height, so as to control the liquid level. For example, the float valve 630 can comprise a floating ball, a connecting rod connected between the floating ball and a blocking seat, and the blocking seat can be hinged to a structure such as a pipeline or a joint at the first liquid inlet, and the hinge point is close to the lower edge. When the floating ball floats up with the rising of the liquid level in the liquid storage tank 610, the floating ball will drive the blocking seat to rotate until the blocking seat blocks the first liquid inlet to block the liquid source from continuously supplying liquid to the liquid storage tank 610. When the floating ball drops with the drop of the liquid level, the floating ball will drive the blocking seat to rotate to open the first liquid inlet, so that the liquid in the liquid source can flow to the liquid storage tank 610.
