DETAILED DESCRIPTION

[0018] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0019] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0020] The present invention provides a humidity control device for a textile workshop, which includes an adjustable air supply port 3, a steam humidification mechanism 4 and a main air duct (not shown in the figure). An induced draft fan (not shown in the figure) is provided at the air inlet end of the main air duct, and a plurality of independent ports are provided at the air outlet end of the main air duct, each of which is connected to an air supply pipe 1 so as to distribute air and steam to various areas of the textile workshop. A control valve is provided at the port of the main air duct so as to realize the air supply control of the air supply pipe 1. An electric auxiliary heating component 46 (such as an electric heating pipe, an electric heating wire) is installed at the air inlet end of the air supply pipe 1, and the air outlet end of the air supply pipe 1 is connected to the adjustable air supply port 3 through a connecting cone pipe 2.

[0021] The induced draft fan starts, sucking in filtered external air, which then enters the main air duct. By adjusting the on and off of the control valve, the air flows through the main air duct to the corresponding air supply duct 1. The steam generated by the steam humidification mechanism 4 is injected into the air supply duct 1 and mixed with the air. According to the actual humidity requirements and layout of the workshop, the adjustable air supply port 3 can adjust the opening and direction of its air outlet, thereby accurately controlling the humidity level in different areas.

[0022] like Figures 1 to 5 As shown, the steam humidification mechanism 4 includes a steam humidification tube 5, a drying tank 8 and a steam generating device (not shown in the figure). A dry steam inlet 20 is provided at one end of the steam humidification tube 5, and two groups of connection ports 19 connected to its inner cavity are provided on the side wall of the steam humidification tube 5. A U-shaped inner tube 18 is sleeved inside the steam humidification tube 5, and the two ports of the inner tube 18 are respectively connected to the corresponding connection ports 19. There are multiple groups of steam humidification tubes 5, and they are distributed equidistantly vertically. The other end of the steam humidification tube 5 is a humidification end, and a plurality of spray holes 12 are provided on the tube body of the humidification end. The humidification ends of these steam humidification tubes 5 pass through the inner cavity of the air supply tube 1 from one side and are fixed.

[0023] All steam humidification pipes 5 are connected in parallel through a pipeline system, and the pipeline system is composed of a plurality of connecting pipes 17 respectively connected to corresponding connection ports 19. One end of the pipeline system is connected to the steam generating device through the main delivery pipe 11, and the other end thereof is connected to the steam inlet 14 of the drying tank 8 through a pipeline. The dry steam inlets 20 of all steam humidification pipes 5 are connected to the second delivery pipe 10 through a connector, and the steam outlet 15 of the drying tank 8 is connected to the second delivery pipe 10 through a first delivery pipe 9, and a regulating valve 16 is installed on the pipeline of the first delivery pipe 9.

[0024] The bottom wall of the air supply pipe 1 near the air outlet is concave to form a water collection tray 6, and a connected drain port 7 is provided at the bottom of the water collection tray 6. During the humidity adjustment process in the textile workshop, condensed water may be generated inside the air supply pipe 1 due to the mixing of air and steam and the change in temperature. If the condensed water is not collected and processed in time, it may drip into the workshop, causing damage to production equipment or products, and may even cause safety hazards. The water collection tray 6 can collect and temporarily store condensed water, and the accumulated liquid can be discharged by opening the drain port 7.

[0025] like Figures 6 to 8As shown, the drying tank 8 is fixed to the outer wall of the air supply pipe 1 through a support frame, and an inverted cone-shaped partition 26 is provided inside the drying tank 8, and the partition 26 divides the inner cavity of the drying tank 8 into a drying chamber and an evaporation chamber. The steam outlet 15 is located at the top of the drying tank 8, and the bottom of the drying tank 8 is provided with a condensed water outlet 13 connected to its inner cavity. The steam inlet 14 is tangent to the outer wall of the drying tank 8 and connected to the evaporation chamber. The partition 26 is provided with a plurality of air inlet holes 22 to allow steam to enter the drying chamber from the evaporation chamber, and the bottom of the partition 26 is provided with a guide pipe 23 facing the condensed water outlet 13.

[0026] A spiral plate 24 spirally ascending around the guide tube 23 is provided in the evaporation chamber, and a vertical guide plate 25 is provided between the upper and lower gaps of the spiral plate 24 (i.e., between the pitches of the spiral plate 24), and the guide plate 25 extends along the direction of the spiral plate 24 (spirally ascending). An air duct 27 is formed between the guide plate 25 and the inner wall of the drying tank 8, and the inlet of the air duct 27 faces the steam inlet 14. The guide plate 25 gradually approaches the inner wall of the drying tank 8 from its starting end, so that the air duct 27 gradually shrinks from the inlet to its outlet.

[0027] The steam enters the evaporation chamber tangentially to form a circulation, and is accelerated by the air duct 27 and then spirally rises. Due to the difference in gravity between the steam and the small water droplets in the steam, the small water droplets have a larger mass, and are more likely to be thrown toward the outer wall of the drying tank 8 under the same centrifugal force than the steam. Under the action of the centrifugal force, the small water droplets in the steam will be gradually separated, and a "stratification" phenomenon will occur between the steam and the water droplets.

[0028] The small water droplets thrown toward the outer wall of the drying tank 8 will collide with each other during the flow process, and due to the surface tension and viscosity between the water droplets, they will combine into larger water droplets. When the gravity of the water droplets is greater than the dynamic force (such as drag force and lift) it receives in the steam flow rate, the behavior of the water droplets is dominated by gravity, and then it flows down along the outer edge of the air duct 27 and finally falls to the bottom of the evaporation chamber.

[0029] The interior of the drying chamber is filled with a mesh adsorption pad 21. When the steam and the residual water droplets pass through the adsorption pad 21, the water droplets collide with the filaments that make up the mesh structure and adhere to the surface. The water droplets diffuse on the surface of the filaments and are affected by gravity, gradually gathering into larger droplets. Using the wettability of the filaments, the surface tension of the liquid and the capillary action, the droplets continue to grow until their own gravity exceeds the combined force of the gas rising force and the surface tension of the liquid, and then fall off the filaments. After being gathered by the partition 26, they fall to the bottom of the evaporation chamber through the guide tube 23.

[0030] like Figures 9 to 12As shown, the adjustable air outlet 3 includes an air cylinder 28 and a shaft seat 30. One end of the air cylinder 28 is fixedly connected to the connecting cone 2, and the other end of the air cylinder 28 is provided with a protective cover, and a driving mechanism is provided inside the protective cover. The protective cover includes two sets of side ring plates 32, which are fixed to the outer side wall of the air cylinder 28 at intervals, and a guard plate 31 is installed between the two sets of side ring plates 32.

[0031] The shaft seat 30 is installed at the axis of the wind tube 28 through the support rod 45. The end of the shaft seat 30 facing the conical tube 2 is provided with a conical guide portion 34, which plays the role of breaking wind and guiding flow. A plurality of fan blades 33 are installed between the shaft seat 30 and the wind tube 28, and the driving mechanism is drivingly connected to all the fan blades 33.

[0032] The driving mechanism includes a guide ring 35, and the outer wall of the wind tube 28 is provided with multiple groups of support frames 40, and the support frames 40 are installed with rollers 41. The guide ring 35 is supported on the outer wall of the wind tube 28 by the rollers 41, so that the guide ring 35 can rotate relative to the wind tube 28. The contact between the rollers 41 and the guide ring 35 provides a stable rolling support for the guide ring 35. The outer wall of the wind tube 28 is also provided with a sleeve 37 corresponding to the fan blade 33, and the rotating shaft 36 of the fan blade 33 passes through the sleeve 37 to ensure the stability of the fan blade 33. A connecting plate 44 is fixed to the end of the rotating shaft 36, and a guide hole 43 is opened at one end of the connecting plate 44. The outer wall of the guide ring 35 is provided with a connecting column 42 corresponding to the connecting plate 44, and the connecting column 42 passes through the corresponding guide hole 43, thereby realizing the connection and synchronous movement between the guide ring 35 and the fan blade 33. A rack 39 is fixed to one side of the guide ring 35 , a servo motor 29 is fixed to one side of the guard plate 31 , a gear 38 is fixed to the motor shaft of the servo motor 29 , and the gear 38 is meshed with the rack 39 .

[0033] When the servo motor 29 is started, it drives the gear 38 to rotate, transmits power through the rack 39, and drives the guide ring 35 to rotate in the circumferential direction. The rotation of the guide ring 35 drives the connecting column 42 thereon to move, and then drives the rotating shaft 36 to rotate, so as to realize the opening and closing of the fan blades 33. By controlling the forward and reverse rotation and the running time of the servo motor 29, the opening and closing of the fan blades 33 and the opening and closing angles can be controlled.

[0034] A number of humidity sensors are installed in the textile workshop to monitor the humidity levels in different areas of the workshop in real time. When the humidity sensor in the area detects that the humidity is lower than the preset value, it immediately sends a command to the control system to control the electric auxiliary heating component 46, the induced draft fan, and the steam generating equipment to start one after another. The induced draft fan is responsible for introducing the filtered external air into the main air duct, and sending it to the air supply duct 1 in the corresponding area by adjusting the on and off of the corresponding control valve. In the air supply duct 1, the air flowing through the electric auxiliary heating component 46 is heated to increase the temperature, and the air supply duct 1, the connecting cone 2 and the adjustable air supply port 3 are preheated, which helps to prevent condensation problems caused by temperature differences during the steam transportation process. After the evaporation supply has been supplied for a period of time, the electric auxiliary heating component 46 stops heating.

[0035] The steam generated by the steam generating device is sent into the pipeline system along the main delivery pipe 11. The pipeline system distributes the steam to the inner pipe 18, and uses the latent heat of the steam to heat the inner cavity of the steam humidification pipe 5 to avoid condensation problems caused by temperature differences. The steam coming out of the pipeline system enters the drying tank 8 to remove the entrained liquid droplets, and then enters each steam humidification pipe 5 through the second delivery pipe 10, and finally sprays out from the spray hole 12. The sprayed steam is mixed with the air introduced by the induced draft fan, thereby increasing the humidity of the air. By adjusting the opening and closing angle of the fan blades 33 in the adjustable air supply port 3, the humid air is delivered to the target area.

[0036] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention.
