DETAILED DESCRIPTION
[0027] The present application is further described in detail below with reference to the accompanying drawings.
[0028] The present application discloses a wet nitrogen drying device, which is used to improve the drying effect of special materials and increase the qualified rate of special materials after drying.
[0029] refer to Figure 1 、 Figure 2A wet nitrogen drying device includes a dryer body 110 and a nitrogen supply structure. The dryer body 110 is provided with a vacuum interface 111 and an air pipe interface 112. The vacuum interface 111 and the air pipe interface 112 are both connected to the dryer body 110. The vacuum interface 111 is sleeved on the air pipe interface 112. The vacuum interface 111 is connected to a three-way valve 113. One end of the three-way valve 113 is connected to the vacuum interface 111, and the other end of the three-way valve 113 is connected to a vacuum tube 114. The three-way valve 113 also has an end through which a gas Tube 115, the air pipe 115 passes through the three-way valve 113 and is connected to the air pipe interface 112. The end of the air pipe 115 away from the nitrogen supply structure is connected to the nitrogen supply structure. The nitrogen supply structure is used to introduce nitrogen with a certain humidity into the dryer body 110. When the special material containing ethanol has a low drying effect under a normal drying environment, the nitrogen with a certain humidity can replace the ethanol with crystallization water, and at the same time make the special material with crystallization water, thereby improving the drying effect of the special material and improving the qualified rate of the special material after drying.
[0030] The nitrogen supply structure includes an adjusting element 120, a hygrometer 130 and a humidifying tank 140, wherein purified water is provided in the humidifying tank 140, and a nitrogen supply pipe 141 and a purified water replenishing pipe 142 are connected to the humidifying tank 140. The nitrogen supply pipe 141 is connected to the bottom of the humidifying tank 140, and the purified water replenishing pipe 142 is connected to the top of the humidifying tank 140. The nitrogen supply pipe 141 replenishes nitrogen into the humidifying tank 140, and the purified water replenishing pipe 142 replenishes purified water into the humidifying tank 140. The nitrogen and the purified water are in contact, and the nitrogen has a certain humidity.
[0031] The top of the humidifying tank 140 is also connected to a delivery pipe 143. The regulating element 120 includes a regulating tank 121 and a nitrogen supply pipe. The end of the delivery pipe 143 away from the humidifying tank 140 is connected to the regulating tank 121 and the delivery pipe 143 is connected to the bottom of the regulating tank 121. Furthermore, the bottom of the humidifying tank 140 and the bottom of the regulating tank 121 are both provided with a drain valve 123. In this embodiment, a DN25 valve 152 is used.
[0032] The nitrogen replenishing pipe replenishes nitrogen into the regulating tank 121. In this embodiment, the nitrogen supply pipe 141 and the nitrogen replenishing pipe both provide nitrogen to the humidifying tank 140 and the regulating tank 121 respectively at a pressure of 0.3 MPa.
[0033] Furthermore, the hygrometer 130 includes a first hygrometer 131 and a second hygrometer 132. The first hygrometer 131 is arranged on the delivery pipe 143, and the first hygrometer 131 is used to monitor the humidity of the nitrogen passing into the regulating tank 121 in real time. The second hygrometer 132 is arranged on the nitrogen replenishing pipe, and the second hygrometer 132 is used to monitor the humidity of the nitrogen passing into the regulating tank 121 in real time. According to the data monitored by the first hygrometer 131 and the second hygrometer 132, the humidity of the nitrogen passing from the regulating tank 121 to the dryer body 110 can be calculated.
[0034] The delivery pipe 143, the purified water replenishment pipe 142, the nitrogen supply pipe 141 and the nitrogen replenishment pipe are respectively connected to control valves. In this embodiment, the control valves on the delivery pipe 143, the nitrogen supply pipe 141 and the nitrogen replenishment pipe are DN15-304 valves 151, and the control valve on the purified water replenishment pipe 142 is DN25 valve 152.
[0035] When the first hygrometer 131 detects that the nitrogen humidity flowing into the regulating tank 121 is high, the control valve on the nitrogen replenishing pipe is opened to replenish nitrogen into the regulating tank 121. The second hygrometer 132 monitors the humidity of the nitrogen flowing into the regulating tank 121 through the nitrogen replenishing pipe. The nitrogen humidity in the regulating tank 121 can be calculated based on the data from the first hygrometer 131 and the second hygrometer 132, thereby ensuring that the nitrogen humidity flowing into the dryer body 110 is at a preset humidity. Similarly, when the first hygrometer 131 detects that the nitrogen humidity flowing into the regulating tank 121 is low, it indicates that the purified water content in the humidification tank 140 is low. The control valve on the purified water replenishing pipe 142 can be opened to replenish purified water into the humidification tank 140, thereby achieving precise control of the nitrogen humidity flowing into the dryer body 110.
[0036] The implementation principle of a wet nitrogen drying device in an embodiment of the present application is as follows: when the drying effect of a special material containing ethanol is low under a normal drying environment, nitrogen with a certain humidity can replace the ethanol with crystallization water, and at the same time make the special material with crystallization water, thereby improving the drying effect of the special material and increasing the qualified rate of the special material after drying.
[0037] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
