The forming process of PPH storage tank adopts spiral extrusion winding technology with reliable quality. The main processes include tank extrusion winding, external welding, internal seam welding, pipe orifice installation, etc. Can body extrusion winding is the process of using PPH spiral extrusion winding unit to process PPH granules into can body molding. The system adopts the process of hot melting PPH particles, extruding them, and then winding them onto steel dies to form cans. The production efficiency of this process is about 5-8 times higher than that of manual process, and the product is flat and beautiful, with good integrity, no joints, good corrosion resistance and leakage resistance. The tank body is thin at the top and thick at the bottom, and the size and shape of the product are not limited. External welding is the process of using the imported automatic extrusion welding unit to make the large weld of the tank with large stress be welded in one time. The new PPH granular material with the same property as the tank body is hot melted at the large weld seam, and is integrated with the tank bottom and tank body. The process features high mechanization and automation, and stable product quality. The weld specifications can be designed according to the stress characteristics of the product to give full play to the integrity of the weld, reduce flash, and make the joint smooth and beautiful. In addition, the ultraviolet absorber is added to PPH granular material to resist aging and extend the service life.

PPH tank body extrusion winding production tank body butt welding is the process of using PPH spiral extrusion winding unit to process PPH particles into tank body molding. The system adopts the process of hot melting PPH particles, extruding them, and then winding them onto steel dies to form cans. The production efficiency is 5-8 times higher than that of manual production. The product has good integrity, no seams, good corrosion resistance, good leakage resistance, flat and beautiful product, thin tank body and thick tank body, low price, unlimited product size and shape, and the product is processed with granular materials, with good anti-aging performance. Polypropylene tank itself has the advantage of internal and external anti-corrosion, so it can be stored in some highly corrosive environments. Because linear polyethylene is used, it has good service performance, and the special structure of polypropylene rolling tank is used, so the service life can basically reach more than 15 years. In addition, it can be used under normal atmospheric temperature and pressure when it is stored.

PPH storage tank mainly includes core processes such as tank body fabrication, bottom, top, manhole, internal and external welding of inlet and outlet flange interface, which will directly affect the integrity, aging resistance, leakage prevention, service life and mechanical strength of the entire PPH storage tank. PPH storage tank body is manufactured by spiral extrusion winding technology. PPH particles are melted on the spiral extrusion winding machine, and then the molten extrusion materials form a can body on the mold. When the temperature is reduced to a certain extent, the tank can be demoulded to ensure the integrity of the tank. However, in the traditional processing form of polypropylene tank, the plate is welded into the tank. Since the very wide plate is 2000 mm, the height of the tank body is generally more than 2000 mm. In actual processing, the tank bodies are welded one by one and then formed manually. Then, for safety reasons, a stiffening ring is added at the connection of the tank.

The internal welding of PPH storage tank is an automatic long arm extrusion welding process, which is an important step in all processes. The new PPH granular material with the same nature as the tank body is hot melted at the internal weld seam, and is integrated with the tank bottom and tank body. The principle is the same as that of external welding, but its equipment is different. Internal welding process characteristics of PPH storage tank: high mechanization and automation, stable product quality; The weld specifications can be designed according to the stress characteristics of the products, so as to give full play to the integrity of the weld; The product has good integrity, the weld is integrated with the parent body, and has good corrosion resistance and leakage resistance; It can reduce flash, and the joints are smooth and beautiful. UV absorber is added to PPH granules to prevent aging and prolong service life.

The working principle of PPH waste gas tower is to separate the pollutants in the gas and convert them into harmless substances to purify the gas. It belongs to differential contact countercurrent type. The packing in the tower body is the basic component of gas-liquid two-phase contact. After the gas outside the tower body enters the tower body, the gas enters the packing layer. On the packing layer, there is spray liquid from the top and spray liquid in front, and a layer of liquid film is formed on the packing. When the gas flows through the packing gap, it contacts with the packing liquid film for absorption or comprehensive reaction, The packing layer can provide sufficient surface area without causing excessive resistance to the gas flow. The absorbed or integrated gas is collected by the demister and discharged out of the tower through the air outlet.

The performance characteristics of PPH storage tank are anti-corrosion and free of leakage. Easy to install, maintain and replace. Long service life, good sealing performance. High polymer plastic sliding roller can prevent the strip steel surface from being pulled during pickling. PPH storage tanks are commonly used for the storage and temporary storage of production materials in chemical, petroleum, medicine, food, grease, printing and dyeing, metallurgy, environmental protection, light industry and other industries. Because PPH storage tank has unique advantages over traditional anti-corrosion tank. Next, the advantages of PPH storage tank are introduced in detail. PPH storage tank has good integrity, no welding, no leakage, impact resistance, high tensile strength, good aging resistance, and meets the hygienic food standards. Due to the good performance of LLDPE and the special structure of polypropylene rolling tank, the service life of LLDPE can reach more than 15 years. Good chemical resistance. Except for some solutions that can make it expand, it can bear most of the material solutions. Polypropylene tank has the characteristics of internal and external anti-corrosion, and can be placed in a highly corrosive environment. Generally, the working conditions of storage tanks are atmospheric temperature and pressure; Under special circumstances, the working conditions of the storage tank can be lower than 70 ℃, and the hydraulic pressure can be less than 1 kg/cm2.
