[0025] Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound, which is a colorless and odorless transparent liquid at room temperature, and is a hygroscopic flammable liquid. It has the characteristics of high polarity, high boiling point, good thermal stability, non-protic, and water miscible, and can be dissolved in ethanol, propanol, benzene and chloroform and most organic substances. It is known as "universal solvent", which can be used as organic solvent, reaction medium and organic synthesis intermediate, and also can be used as dyeing solvent, dye removal agent, dyeing carrier and absorption agent for recovering acetylene and sulfur dioxide of synthetic fibers.

[0026] Dimethyl sulfoxide has higher requirements for moisture control, especially in medical and electronic product application fields. At present, in the related technology, dimethyl sulfoxide generated by continuous preparation process is transported to DMSO temporary storage tank for temporary storage, and then transported to DMSO storage tank through material conveying pipeline for storage and sales. However, during the transportation of dimethyl sulfoxide from the DMSO temporary storage tank to the DMSO storage tank, there is humid air in the material conveying pipeline and the inside of the DMSO storage tank, and dimethyl sulfoxide has hydrophilicity and is easy to absorb water in a humid environment, resulting in unqualified moisture index of dimethyl sulfoxide, affecting product quality and use range, and causing economic loss to enterprises.

[0027] In order to solve the above problems, the application provides a dimethyl sulfoxide continuous automatic moisture-proof storage system, and the embodiments of the application are further described below with reference to the drawings.

[0028] Reference Figure 1The application provides a continuous automatic humidity isolation storage system for dimethyl sulfoxide, which comprises a DMSO temporary storage tank 100, a control device, two DMSO storage tanks 400, two feeding pipelines 110, two material automatic control valves 120, two DMSO storage tanks 400, two material level detectors 410, two moisture detectors, two pressure detectors, two nitrogen conveying pipelines 210, two nitrogen control valves 220, two gas phase conveying pipelines 320 and two storage tank breather valves 330; the DMSO storage tank 400 is in one-to-one correspondence with the feeding pipeline 110, the material automatic control valve 120, the DMSO storage tank 400, the material level detector 410, the moisture detector, the pressure detector, the nitrogen conveying pipeline 210, the nitrogen control valve 220, the gas phase conveying pipeline 320 and the storage tank breather valve 330, respectively; two material output ends are arranged on the DMSO temporary storage tank 100, and the two material output ends are in one-to-one correspondence with the two feeding pipelines 110; the input end of the feeding pipeline 110 is connected with the corresponding material output end on the DMSO temporary storage tank 100; the output end of the feeding pipeline 110 is connected with the input end of the corresponding DMSO storage tank 400; the material automatic control valve 120 is arranged on the corresponding feeding pipeline 110; the output end of the nitrogen conveying pipeline 210 is communicated with the corresponding feeding pipeline 110 and the inside of the corresponding DMSO storage tank 400 through the feeding pipeline 110; the material automatic control valve 120 is arranged close to the DMSO temporary storage tank 100; the nitrogen control valve 220 is arranged on the corresponding nitrogen conveying pipeline 210; the material level detector 410, the moisture detector and the pressure detector are arranged on the corresponding DMSO storage tank 400, respectively; the gas phase conveying pipeline 320 is communicated with the inside of the DMSO storage tank 400 through the gas phase conveying port on the corresponding DMSO storage tank 400; and the storage tank breather valve 330 is arranged on the corresponding gas phase conveying pipeline 320; the control device is connected with each material automatic control valve 120, nitrogen control valve 220, material level detector 410, moisture detector and pressure detector, respectively.

[0029] It should be noted that by setting the tank breather valve 330 in the gas phase conveying pipeline 320, the pressure in the corresponding DMSO storage tank 400 is controlled, the gas leakage is reduced, and the tank explosion is prevented. The most important role of the tank breather valve 330 is to control the pressure difference between the inside and outside of the DMSO storage tank 400, thereby controlling the pressure in the DMSO storage tank 400. When the pressure in the DMSO storage tank 400 rises, the tank breather valve 330 will automatically open to release the excessive pressure, so that the pressure in the DMSO storage tank 400 does not exceed the predetermined value. On the contrary, when the pressure in the DMSO storage tank 400 decreases, the tank breather valve 330 will automatically close and suck the air outside into the DMSO storage tank 400 through the pipeline to keep the pressure in the DMSO storage tank 400 from being too low. The volatile liquids such as chemicals and petroleum in the DMSO storage tank 400 will be affected by the external air pressure, resulting in evaporation and leakage. If there is no breather valve installed inside the tank, the risk of gas leakage will increase. The tank breather valve 330 can reduce the risk of gas leakage by adjusting the pressure difference between the inside and outside of the DMSO storage tank 400. Because excessive high or low pressure may cause the DMSO storage tank 400 to explode and cause irreparable loss to the manufacturer and workers, one of the functions of the tank breather valve 330 is to reduce the risk of pressure change by adjusting the pressure difference between the inside and outside of the DMSO storage tank 400, thereby avoiding the explosion of the DMSO storage tank 400.

[0030] It should be noted that by nitrogen sealing the DMSO storage tank 400, the humidity in the DMSO storage tank 400 can be controlled. The humidity in the DMSO storage tank 400 has an important influence on the quality and stability of the stored dimethyl sulfoxide. By nitrogen sealing, the humidity can be controlled, the entry of moisture can be reduced, and the stability of the stored material can be maintained. The nitrogen sealing of the DMSO storage tank 400 can reduce the contact between the stored material and the external environment, reduce the risk of accidents and pollution, and thus improve the safety of the storage system.

[0031] It should be noted that, Figure 1 P1 and P2 in the formula respectively represent pressure detectors corresponding to the two DMSO storage tanks 400.

[0032] In the present application, the material level detector 410 is used to detect the liquid level of the material in the corresponding DMSO storage tank 400 in real time, obtain the material level detection result and send it to the control device, the moisture tester is used to measure the moisture content in the corresponding DMSO storage tank 400 in real time, obtain the storage tank moisture content detection result and send it to the control device, and the pressure detector is used to detect the pressure in the corresponding DMSO storage tank 400 in real time, obtain the current pressure value and send it to the control device; before the dimethyl sulfoxide material is transported into the DMSO storage tank 400, the control device controls the nitrogen control valve 220 to open, and the nitrogen delivery pipeline 210 injects nitrogen into the corresponding DMSO storage tank through the corresponding feeding pipeline 110, expelling the air in the feeding pipeline 110 and the DMSO storage tank 400. In the static state, nitrogen can fully fill the feeding pipeline 110 and the tank space of the DMSO storage tank 400, effectively expelling the air from the corresponding gas phase delivery pipeline 320, and the control device is used to control one of the two material control valves to open, and the dimethyl sulfoxide material temporarily stored in the DMSO temporary storage tank 100 is transported from the feeding pipeline 110 corresponding to the open material control valve to the corresponding DMSO storage tank 400 for storage. At the same time, when the pressure in the DMSO storage tank 400 is too high, the tank breather valve 330 will automatically open, and the nitrogen in the tank will be squeezed out of the corresponding gas phase delivery pipeline 320 while the material is being transported into the tank; when the control device determines that the moisture content detection result in the DMSO storage tank 400 exceeds the preset threshold value of the moisture in the tank, the control device controls the corresponding material automatic valve 120 to close, and performs nitrogen sealing operation on the DMSO storage tank 400, and at the same time, the control device controls the other material automatic valve 120 to open, so that the dimethyl sulfoxide material in the DMSO temporary storage tank 100 can continue to be transported from the other material delivery pipeline to the other DMSO storage tank 400 for storage, realizing continuous automatic moisture-proof storage of dimethyl sulfoxide. By using the tank body to seal and isolate the storage of dimethyl sulfoxide, dimethyl sulfoxide will not come into contact with the outside air, so it will not absorb the moisture in the air, and the storage effect is good. Through this setting, the continuous automatic moisture-proof storage of dimethyl sulfoxide can be realized, and the problem of unqualified quality caused by the absorption of moisture in the humid air during storage of dimethyl sulfoxide can be effectively avoided.

[0033] Reference Figure 1 It can be understood that the dimethyl sulfoxide continuous automatic moisture-proof storage system also includes a waste gas treatment device 300, and the one end of the gas phase delivery pipeline 320 away from the corresponding DMSO storage tank 400 is connected to the input end of the waste gas treatment device 300.

[0034] It should be noted that by setting the waste gas treatment device 300, the waste gas transported from the gas phase conveying pipeline 320 is purified and directly discharged to pollute the environment.

[0035] Referring to Figure 1 It can be understood that the dimethyl sulfoxide continuous automatic humidity isolation storage system further comprises a waste gas output pipeline 310, and the input end of the waste gas output pipeline 310 is connected with the input end of the waste gas treatment device 300.

[0036] It should be noted that by setting the waste gas output pipeline 310 on the waste gas treatment device 300, the waste gas is discharged from the waste gas output pipeline 310 after the waste gas treatment device 300 purifies the transported waste gas to meet the standard.

[0037] Referring to Figure 1 It can be understood that the dimethyl sulfoxide continuous automatic humidity isolation storage system further comprises a nitrogen tank 200, and the nitrogen tank 200 is provided with two nitrogen output ports, and the two nitrogen output ports correspond to the two nitrogen conveying pipelines 210 one by one, and the output end of the nitrogen conveying pipeline 210 is communicated with the inside of the nitrogen tank 200 through the corresponding nitrogen output port.

[0038] It should be noted that the nitrogen tank 200 is used for storing nitrogen.

[0039] It can be understood that the nitrogen control valve 220 is a self-sealing nitrogen valve.

[0040] It should be noted that the self-sealing nitrogen valve is a valve used for controlling the flow of nitrogen in the pipeline.

[0041] In some embodiments, the main components of the self-sealing nitrogen valve include a valve body, a spring, an adjusting rod, a sealing ring, etc. When it is necessary to control the flow of nitrogen, the opening degree of the valve can be changed by adjusting the adjusting rod, so as to control the flow of nitrogen. At the same time, due to the use of sealing ring and spring and other components, the valve has good sealing performance and can effectively prevent nitrogen leakage.
