Wuhan low-temperature liquid oxygen storage tank service life 20 cubic meters low-temperature storage tank price

Description :

　　The radius between oxygen (including liquid oxygen) storage tanks should not be less than the larger of the adjacent tanks. The safe distance between oxygen acetylene cylinders is 5M, and the safe distance between oxygen acetylene and fire sources is 10M. Liquid oxygen storage tanks are suitable for liquid storage of gases such as liquid oxygen and carbon dioxide. Due to their large capacity, liquid oxygen storage tanks can reduce a lot of transportation costs and human resources, and are widely used in gas manufacturing, hospitals, etc., as a centralized gas supply method.

　　Precautions for safe use of liquid oxygen storage tanks: 1. Liquid oxygen storage tanks are generally placed in a safe location near the air separation unit, away from sources of fire, heat, and combustibles. Overpressure of the storage tank is strictly prohibited. 2. Liquid oxygen has magnetic susceptibility, and under the action of discharge, it is easy to form highly chemically active ozone, which is a detonation excitation energy source. therefore

　　Within a radius of 30m around the liquid oxygen storage tank, open flames or electric sparks are strictly prohibited, and explosion-proof electrical appliances must be used. 3. The liquid oxygen in the liquid oxygen storage tank continues to evaporate, and the concentration of acetylene may increase, resulting in accumulation and precipitation. In order to prevent explosion, the liquid oxygen in the liquid oxygen storage tank should be filled and used as much as possible, regularly updated to prevent acetylene accumulation. The acetylene content in the liquid oxygen should be analyzed once a week, and if it exceeds the standard, the liquid oxygen should be emptied. 4. The pressure gauge, vacuum gauge, liquid level gauge, alarm system, safety valve, etc. of the liquid oxygen storage tank should be regularly calibrated to ensure accuracy, sensitivity, and safety.

　　When there is pressure inside the liquid oxygen storage tank, maintenance or fastening is prohibited. When operating under pressure, the staff must develop safety measures and operating procedures.

　　Acetylene cylinders should be equipped with specialized flashback arresters and pressure reducers according to safety regulations. For workplaces that are not fixed or move frequently, they should be installed on dedicated carts. It is strictly prohibited to strike, collide, or apply strong vibrations to prevent the porous packing inside the cylinder from sinking and forming voids, which may affect the storage of acetylene. Acetylene cylinders should be placed upright and should not be used lying down. Because using it lying down can cause acetone in the bottle to flow out with acetylene, and even flow into the rubber tube through the pressure regulator, which is very dangerous. Use a specialized wrench to open the acetylene cylinder. When opening the acetylene cylinder, the operator should stand behind the valve port and move gently and slowly. It is strictly prohibited to exhaust the gas inside the bottle. In winter, 0, 1~0, and 2 MPa should be left, and in summer, 0 and 3 MPa of residual pressure should be left. The usage pressure should not exceed 0.15 Mpa, and the gas transmission speed should not exceed 1.5~2 cubic meters (m3) per hour The temperature of cylinders and acetylene cylinders should not exceed 40C ° C, and they should be protected from direct sunlight in summer. Excessive temperature inside the bottle can reduce the solubility of acetone in acetylene, leading to a sharp increase in pressure inside the bottle.
