However, this design method has a hidden danger of liquid storage tank pollution. After the discharged liquid is reheated by steam, the gas pressure increases. When the discharge port is not enough to completely release the pressure, the reheated gas will pass through the automatic control valve of the discharge. Anti-sleeping into the liquid tank delivery pipeline (automatic regulating valves are not completely tight in the strict sense, and there are certain leaks), which will seriously pollute the liquid storage tank

The invention discloses a device for preventing a liquid storage tank from being polluted and a control method and belongs to the technical field of liquid temporary storage equipment. The device for preventing the liquid storage tank from being polluted comprises a liquid purity analysis mechanism, a liquid storage mechanism and a liquid discharge mechanism. The liquid storage mechanism is connected with air separation equipment through the liquid purity analysis mechanism. The liquid discharge mechanism is also connected with the air separation equipment through the liquid purity analysis mechanism. By means of the device for preventing the liquid storage tank from being polluted and the control method, the situation that after discharged liquid is reheated by steam in an evaporation cylinder, the pressure of gas rises, and the reheated gas flows back into the liquid storage tank through an automatic discharge control valve and pollutes the liquid storage tank when discharge outlets are insufficient and the pressure is completely released can be prevented.
Description
technical field [0001] The invention relates to the technical field of liquid temporary storage equipment, in particular to a device and control method for preventing contamination of a liquid storage tank. Background technique [0002] At present, the smelting of high-quality steel in the metallurgical industry requires higher and higher purity of nitrogen and argon. Generally, the purity is required to be above 99.9995%. If the purity of the gas supply is low, it will have a serious impact on the quality of special steel. Therefore, the air separation system responsible for gas supply must ensure the purity of liquid nitrogen and liquid argon. [0003] At present, the air separation equipment can not only produce gas products with qualified purity, but also produce liquid products with higher purity. The liquid delivery pipeline and the liquid discharge pipeline are connected together. The liquid discharge of liquid oxygen, liquid nitrogen and liquid argon is generally di...
