[0015] Preferably, a first sealing plate is slidably connected inside the first compression chamber, and one end of a first spring is fixedly connected to the lower surface of the first sealing plate. The first spring is fixedly connected to the upper surface of the fixed chamber. A connector is provided below the first sealing plate.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects: Air is heated by heating wires in the heating chamber and enters the drying chamber, where the water vapor of the product in the drying chamber is vaporized. The air then passes through a filter chamber and a heat exchange chamber to reach the condenser. The high-temperature wet steam comes into contact with the condensing fins in the condenser, and the steam liquefies into water droplets upon cooling, flowing down the condensing fins into the collection tank. The dried air returns to the heat exchange chamber through a second pipeline. The design of the second pipeline being wound around the first pipeline allows the air in the second pipeline to be preheated before entering the drying chamber. The air is then heated by the heating chamber (the energy required to heat to the required temperature is reduced) and enters the drying chamber. By dehumidifying the high-temperature wet steam generated during the drying of triazole, the problem of high energy consumption caused by the high humidity of the high-temperature wet steam generated during the drying process cannot be recovered and utilized. Furthermore, the preheating of the air entering the heating chamber by the high-temperature wet steam reduces the heating power consumption of the heating wires. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Example 1

[0029] Please see Figure 1The present invention provides a technical solution: a high-temperature wet steam dehumidification device for drying equipment, comprising a drying box 1, a heat exchange box 3 disposed on one side of the drying box 1, a first pipe 4 disposed inside the heat exchange box 3, the drying box 1 being connected to a condenser 5 through the first pipe 4, a heating box 8 disposed below the drying box 1, the heating box 8 being connected to the condenser 5 through a second pipe 7 disposed inside the heat exchange box 3, and heat exchange occurring between the second pipe 7 and the first pipe 4.

[0030] Preferably, the second conduit 7 is wound around the first conduit 4;

[0031] The outer layer of the heat exchange box 3 is made of heat insulation material.

[0032] Preferably, a liquid collection tank 6 is provided below the condenser 5, the lower surface of the condenser 5 is "V" shaped, and a guide hole is provided at the center line of the lower surface of the condenser 5;

[0033] The condenser 5 is equipped with condensing fins 9, which are connected to refrigeration equipment located outside the condenser 5.

[0034] Preferably, the heating chamber 8 is provided with a heating wire 10, which is used to heat the air entering the heating chamber 8 from the second pipe 7.

[0035] Preferably, a filter box 2 is provided between the drying box 1 and the heat exchange box 3, and a filter layer is provided at the connection between the filter box 2 and the first pipeline 4.

[0036] The working principle and beneficial effects of the above scheme are as follows:

[0037] Air is heated by heating wire 10 in heating chamber 8 and enters drying chamber 1, where the water vapor of the product in drying chamber 1 is vaporized. The air then passes through filter chamber 2 and heat exchange chamber 3 to reach condenser 5. The high-temperature wet steam comes into contact with the condensing fins 9 in condenser 5, and the steam liquefies into water droplets upon cooling, flowing down the condensing fins 9 into collection chamber 6. The dried air returns to heat exchange chamber 3 through second pipe 7. The design of second pipe 7 being wound around first pipe 4 allows the air in second pipe 7 to be preheated before being heated by heating chamber 8 (the energy required to heat to the required temperature is reduced) and then enters drying chamber 1. By dehumidifying the high-temperature wet steam generated during triazole drying, the problem of high energy consumption caused by the high humidity of the high-temperature wet steam generated during drying cannot be recovered and utilized due to the high humidity of the product. Furthermore, the preheating of the air entering heating chamber 8 by high-temperature wet steam reduces the heating power consumption of heating wire 10.

[0038] Example 2

[0039] Please see Figure 2-3 Based on Embodiment 1, an adjustment device 11 is provided between the second pipeline 7 and the heating box 8. The adjustment device 11 includes a first compression chamber 1103. One end of the first compression chamber 1103 is fixedly connected to a fusion joint 1101. The fusion joint 1101 is provided with a first inlet 1114 and a second inlet 1115. The first inlet 1114 is connected to the second pipeline 7, and the second inlet 1115 is connected to an air pump.

[0040] The other end of the first compression chamber 1103 is fixedly connected to a fixed chamber 1109, the fixed chamber 1109 is fixedly connected to an outlet 1110, and the outlet 1110 is fixedly connected to the heating box 8.

[0041] Preferably, a first sealing plate 1102 is slidably connected inside the first compression chamber 1103, and one end of a first spring 1105 is fixedly connected to the lower surface of the first sealing plate 1102. The first spring 1105 is fixedly connected to the upper surface of the fixed chamber 1109. A connector 1104 is provided below the first sealing plate 1102. The connector 1104 is fixedly connected to the fixed chamber 1109, and the connector 1104 is hollow and communicates with the outlet 1110.

[0042] Two sets of first contacts 1106 are fixedly connected to the lower end of the inner wall of the first compression chamber 1103. When the two sets of first contacts 1106 are turned on, the heating wire 10 works.

[0043] A second compression chamber 1111 is provided inside the fixed chamber 1109. The second compression chamber 1111 is connected to the outlet 1110. A second sealing plate 1112 is slidably connected inside the second compression chamber 1111. One end of a connecting rod 1108 is fixedly connected to the second sealing plate 1112. The connecting rod 1108 is in the form of... The connecting rod 1108 passes through the fixed chamber 1109. The middle section of the connecting rod 1108 is connected to the fixed chamber 1109 by a second spring 1113. A second contact 1107 is provided on the outer side of the other end of the connecting rod 1108. The air pump works when the two sets of second contacts 1107 are connected.

[0044] Among them, the two sets of connecting rods 1108 are electrically connected.

[0045] Preferably, the first sealing plate 1102 is provided with a plug groove 1116, a fixing plate 1118 is fixedly connected in the plug groove 1116, a sliding plate 1117 is slidably connected in the plug groove 1116, and the sliding plate 1117 is slidably connected to the fixing plate 1118. A third spring 1119 is provided between the sliding plate 1117 and the side of the plug groove 1116, and the two ends of the third spring 1119 are fixedly connected to the sliding plate 1117 and the plug groove 1116, respectively.

[0046] The working principle and beneficial effects of the above scheme are as follows:

[0047] When the air pressure entering the first inlet 1114 through the second pipe 7 is greater than the elastic force of the first spring 1105, the air pressure causes the first sealing plate 1102 to move and gradually approach the plug 1104. When the air pressure reaches the preset pressure, the plug 1104 contacts the sliding plate 1117 and squeezes the sliding plate 1117 to overcome the elastic force of the third spring 1119 and slide to both sides. When the first sealing plate 1102 moves to the plug 1104 and squeezes the sliding plate 1117 to open, the two sets of first contacts 1106 contact the first sealing plate 1102 and conduct the two sets of first contacts 1106. The heating wire 10 works to heat the incoming air. When the airflow reaches the preset pressure, it is conducted and heated at the same time, so that the temperature of the airflow can be maintained within a certain range. Moreover, heating the air when it is conducted can avoid energy waste (when the heating wire 10 works but no airflow enters).

[0048] When the air pressure inside the heating chamber 8 is low and cannot meet the efficiency requirements for product drying, since the second compression chamber 1111 is connected to the heating chamber 8 through the outlet 1110, the low air pressure inside the second compression chamber 1111 will cause the second sealing plate 1112 to drive the connecting rod 1108 to move towards the center against the elastic force of the second spring 1113 until the connecting rod 1108 contacts the second contact point 1107 (the connecting rod 1108 connects the two sets of second contact points 1107). The air pump will then work to pump outside air into the second inlet 1115, so that the heat power of the heating wire 10 inside the heating chamber 8 and the airflow are maintained at a certain ratio. This will further enable the airflow temperature to be maintained within a certain range, which is beneficial for controlling the drying and dehumidification time of the product and improving the quality of the product (triazole).

[0049] Example 3

[0050] Please see Figure 4-6Based on embodiments 1-2, a cleaning device 12 is provided inside the filter box 2. The cleaning device 12 includes a bracket 1201, which is fixedly connected to the top of the filter box 2. A mounting plate 1204 is fixedly connected to the top of the bracket 1201. A motor 1202 is fixedly connected to the filter box 2. One end of a first rotating shaft 1203 is fixedly connected to the output end of the motor 1202. The other end of the first rotating shaft 1203 is rotatably connected to the mounting plate 1204. A first gear 1205 is fixedly connected to the first rotating shaft 1203. The first gear 1205 meshes with a second gear 1206. The second gear 1206 is fixedly connected to a second rotating shaft 1207. The upper end of the second rotating shaft 1207 is rotatably connected to the mounting plate 1204. The lower end of the second rotating shaft 1207 is inserted into a threaded shaft 1208. The threaded shaft 1208 is threadedly connected to the upper surface of the filter box 2.

[0051] The joint section between the second rotating shaft 1207 and the threaded shaft 1208 is non-circular.

[0052] Preferably, the lower end of the threaded shaft 1208 penetrates the upper surface of the filter box 2, and the threaded shaft 1208 located inside the filter box 2 is fixedly connected to the limiting plate 1209, and a drive ring 1216 is rotatably connected to the edge of the limiting plate 1209.

[0053] A drive gear 1211 is rotatably connected to the limiting plate 1209, and the drive gear 1211 meshes with the drive ring 1216;

[0054] A second pulley 1212 is fixedly connected to the drive gear 1211, and a first pulley 1210 is fixedly connected to the threaded shaft 1208. The first pulley 1210 and the second pulley 1212 are connected by a belt.

[0055] A column 1215 is fixedly connected to the drive ring 1216, and a rotating ring 1214 is sleeved on the drive ring 1216. An arc-shaped groove is provided inside the rotating ring 1214, and the column 1215 is slidably connected to the arc-shaped groove inside the rotating ring 1214.

[0056] The rotating ring 1214 is provided with cleaning bristles;

[0057] The limiting plate 1209 is provided with a limiting groove 1213, and the rotating ring 1214 is located in the limiting groove 1213.

[0058] The working principle and beneficial effects of the above scheme are as follows:

[0059] When motor 1202 starts, it drives the first gear 1205 to rotate. The second gear 1206, meshing with the first gear 1205, drives the second shaft 1207 to rotate. Because the joint between the second shaft 1207 and the threaded shaft 1208 is non-circular, and the threaded shaft 1208 is threadedly connected to the filter box 2, the threaded shaft 1208 moves up and down with the rotation of the second shaft 1207. Through the cooperation of the first pulley 1210 and the second pulley 1212, the rotation of the threaded shaft 1208 is transmitted to the drive gear 1211. Due to the meshing of the drive gear 1211 with the drive ring 1216 and the transmission ratio between the first pulley 1210 and the second pulley 1212, the speeds of the drive ring 1216 and the threaded shaft 1208 are different. The drive ring 1216 and the limiting plate 1209 rotate at different speeds, resulting in relative movement between them. The column 1215 on the drive ring 1216 slides through the arc-shaped groove of the rotating ring 1214, which is limited by the limiting groove 1213 on the limiting plate 1209. This causes the rotating ring 1214 to rotate around the drive ring 1216. Ultimately, the movement of the rotating ring 1214 is a composite movement consisting of rotation around the threaded shaft 1208, rotation around the drive ring 1216, and up-and-down movement along the inner wall of the filter box 2. This means that the rotating ring 1214 can contact any position on the inner wall of the filter box 2. The cleaning bristles on the outside of the rotating ring 1214 completely clean the inner wall and filter layer of the filter box 2 as the rotating ring 1214 moves, avoiding both waste and interference with the passage of high-temperature wet steam.

[0060] Example 4

[0061] Based on embodiments 1-3 above, a turbine fan is installed in the gas pipeline. The turbine fan is used to regulate the gas flow rate in the gas pipeline. The turbine fan adjusts the gas flow rate in the gas pipeline to a target flow rate, which is obtained by a flow rate determining device. The flow rate determining device includes:

[0062] The first temperature sensor is installed at the inlet of condenser 5 to detect the temperature of the high-temperature wet steam at the inlet of condenser 5.

[0063] The second temperature sensor is located at the outlet of condenser 5 and is used to detect the gas temperature at the outlet of condenser 5.

[0064] The third temperature sensor is installed inside the heating chamber 8 and is used to detect the gas temperature inside the heating chamber 8.

[0065] The first humidity sensor is installed at the inlet of condenser 5 to detect the relative humidity of the high-temperature wet steam at the inlet of condenser 5;

[0066] The second humidity sensor is located at the outlet of condenser 5 and is used to detect the relative humidity of the gas at the outlet of condenser 5.

[0067] A controller, electrically connected to the first temperature sensor, the second temperature sensor, the third temperature sensor, the first humidity sensor, and the second humidity sensor respectively, operates based on the first temperature sensor, the second temperature sensor, the third temperature sensor, the first humidity sensor, and the second humidity sensor, and includes:

[0068] Step 1: The controller obtains the target rotational speed of the turbine fan based on the first temperature sensor, the second temperature sensor, the third temperature sensor, the first humidity sensor, the second humidity sensor, and the formula:

[0069]

[0070] Where A is the target speed of the turbine fan, W1 is the temperature of the high-temperature wet steam at the inlet of the condenser 5 detected by the first temperature sensor, W2 is the gas temperature at the outlet of the condenser 5 detected by the second temperature sensor, W3 is the gas temperature inside the heating box 8 detected by the third temperature sensor, S1 is the relative humidity of the high-temperature wet steam at the inlet of the condenser 5 detected by the first humidity sensor, S2 is the relative humidity of the gas at the outlet of the condenser 5 detected by the second humidity sensor, A0 is the preset speed of the turbine fan, and e is the natural constant.

[0071] Step 2: The controller controls the turbine fan to adjust its speed to the target speed, thereby changing the gas flow rate to obtain the optimal gas flow rate for dehumidification and drying of the equipment.

[0072] The working principle and beneficial effects of the above technical solution are as follows: A first temperature sensor is installed at the inlet of condenser 5 to detect the temperature of the high-temperature humid steam at the inlet of condenser 5; a second temperature sensor is installed at the outlet of condenser 5 to detect the gas temperature at the outlet of condenser 5; a third temperature sensor is installed inside the heating chamber 8 to detect the gas temperature inside the heating chamber 8; a first humidity sensor is installed at the inlet of condenser 5 to detect the relative humidity of the high-temperature humid steam at the inlet of condenser 5; and a second humidity sensor is installed at the outlet of condenser 5 to detect the relative humidity of the gas at the outlet of condenser 5. Then, based on the temperatures of the high-temperature humid steam at the inlet of condenser 5 detected by the first temperature sensor, the gas temperature at the outlet of condenser 5 detected by the second temperature sensor, the gas temperature inside the heating chamber 8 detected by the third temperature sensor, the relative humidity of the high-temperature humid steam at the inlet of condenser 5 detected by the first humidity sensor, the relative humidity of the gas at the outlet of condenser 5 detected by the second humidity sensor, and the formula, the target speed of the turbine fan can be calculated. The controller then controls the turbine fan to adjust its speed to the target speed, thereby changing the gas flow rate and obtaining the optimal gas flow rate for dehumidification and drying, which helps to increase the dehumidification and drying efficiency of the equipment and save energy.
