During the processing of PPH winding tank, there are three core points: tank body fabrication, internal and external weld welding, and manhole installation. These three core points will affect the integrity, aging resistance, leakage resistance, service life, mechanical strength and other properties of the tank. PPH granular material is melted on the spiral extrusion winding unit, and then the melted extrusion material forms a tank on the mold, and demoulding is carried out after the temperature is reduced to a certain degree, so as to ensure the integrity of the tank. However, the traditional processing method is plate butt welding to form a tank body. Since the z width of the plate is 2000 mm and the tank body height is generally more than 2000 mm, in actual processing, the tank body is formed by manual welding of sections of the tank body. Then, to be safe, a stiffening ring is added at the joint of the tank body. PPH winding tank is formed by direct processing of PPH particles, without secondary processing. Traditionally, particles are processed into plates, and then the plates are processed into tank bodies; In addition, the PPH winding tank has no problems of joints, welds and leakage, and the overall mechanical strength is far greater than that of tanks processed by traditional processes because of the need for chamfer welding.

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.

HDPE is a part of the plastic recycling market with rapid growth. This is mainly because it is easy to reprocess, has a limited degradation characteristics and is widely used in packaging. The main recycling is to reprocess 25% of recycled materials, such as post consumer recyclables (PCR), with pure HDPE to make bottles not in contact with food. In addition, due to the good insulation performance of HDPE storage tanks, polyethylene is used in many cables, and has good impact resistance even in low environment, In addition, this type of storage tank is more convenient for processing, and can be processed again after use, but it can not be used in industries directly contacting food after secondary processing.

PPH waste gas treatment tower is generally divided into cylindrical tower body or square tower body. The cylindrical tower body is generally vertical tower, and the square tower body is generally horizontal tower. There are multi-stage packing rings inside. During operation, the waste gas flows upward from the bottom of the tower. Due to tangential entry into the tower, especially the guiding effect of the packing layer, the flue gas rotates and rises, resulting in full contact between the packing layer and the waste gas, which sprays the downstream liquid into droplets, leaving a large contact area between gas and liquid; The liquid droplets will also be driven by the air flow to rotate, and the centrifugal force generated will strengthen the air contact at night. They will fall onto the tower wall and flow down along the wall, passing through the overflow device to the next layer of packing, and then the spray nozzle will atomize again for gas-liquid contact.
