BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the structure of the present invention; Figure 2 It is a schematic diagram of the distribution of the inner clamping grooves in the water boiling kettle; Figure 3 It is the salt water concentration curve in the experiment. DETAILED DESCRIPTION
[0012] like Figure 1-3 As shown, a salt water boiling test device for offshore photovoltaic glass comprises a constant temperature water bath 1 with a magnetic stirring function, a cylindrical water boiling kettle 2 and silicone oil for heat exchange are placed in the constant temperature water bath 1, and the top of the water boiling kettle 2 extends out of a part of the constant temperature water bath 1. The water boiling kettle 2 is filled with salt water 11 with a concentration of 5%, and the liquid level of the salt water 11 is located below the constant temperature water level of the constant temperature water bath 1.
[0013] A group of slots 3 corresponding to the photovoltaic glass 12 are evenly distributed at the bottom of the water boiling kettle 2. There are four slots 3, and each slot 3 is a right triangle structure and is distributed in a diagonal line. In this way, the four photovoltaic glass sheets 12 inserted therein are distributed in a square.
[0014] A magnetic stirring rotor 4 of a constant temperature water bath 1 is placed on the bottom surface of the water boiling kettle 2 inside the slot 3 , that is, inside the four photovoltaic glass sheets 12 .
[0015] A probe insertion hole 8 is provided at the center of the kettle cover 2a on the top of the water boiling kettle 2, and two liquid replenishing holes 10 are provided on the edge of the kettle cover 2a, so that the liquid replenishing holes 10 are all located outside the photovoltaic glass sheet 12. This is because when the photovoltaic glass sheet 13 is inserted into the slot 3, the coating surface of the photovoltaic glass sheet 12 is all distributed inward.
[0016] A placement rack 5 is provided on one side of the constant temperature water bath 1, and a fluid infusion bucket 6, a conductivity meter 7 and a fluid infusion peristaltic pump 8 are placed on the placement rack 5. The conductivity meter 7 and the fluid infusion peristaltic pump 8 form an electrical signal control coordination. The monitoring end 7a of the conductivity meter 7 is inserted into the water boiling kettle from the probe insertion hole 8 and immersed in the salt water 11. The infusion tube 8a of the fluid infusion peristaltic pump 8 has two parallel water outlet ends, and the water outlet ends are closed and inserted into the fluid infusion hole 10 and immersed in the salt water 11.
[0017] A steam discharge hole 14 is also provided on the kettle cover 2a, and a corresponding plug 14a is inserted into the steam discharge hole 14.
[0018] Working process: The photovoltaic glass sheets in the boiling kettle were subjected to a salt water boiling test in a constant temperature water bath. During the test, the conductivity meter constantly detected the concentration of the salt water. Once the concentration exceeded 5%, the conductivity meter started the replenishment peristaltic pump to replenish the pure water in the replenishment bucket into the boiling kettle. After the concentration of the salt water in the boiling kettle returned to 5%, the conductivity meter turned off the replenishment peristaltic pump, thereby ensuring that the concentration of the salt water was always maintained at 5% during the salt water boiling test.
[0019] According to the needs of the experiment, when the constant temperature water bath heats up slowly, less steam is generated and can directly overflow through the gap between the probe insertion hole and the liquid filling hole. However, if the constant temperature water bath needs to heat up quickly and maintain high heating power, more steam will be generated. At this time, the plug on the steam discharge hole will be opened to release a large amount of steam.
