For the treatment of corrosive gases (such as acid and alkaline waste gas) in PPH waste gas tower, liquid absorption method is often used. The key to control the waste gas by liquid absorption is the selection of purification equipment. The main development is acid and alkaline waste gas purification process and equipment with high purification efficiency, simple operation and management, and long service life. This process and product are characterized by simple structure, low energy consumption, high purification efficiency and wide application range, and can effectively remove water-soluble gases such as hydrogen chloride (HCl), hydrogen fluoride (HF), ammonia (NH3), sulfuric acid mist (H2SO4), chromic acid mist (CrO3), cyanuric acid gas (HCN), alkali vapor (NaOH), hydrogen sulfide gas (H2S), formalin (HCHO), etc. The acid mist waste gas is introduced into the purification tower through the air duct. After passing through the packing layer, the waste gas and sodium hydride absorption liquid are fully contacted, absorbed and neutralized by gas-liquid two-phase reaction. After purification, the acid mist waste gas is dewatered and defogged by the demister, and then discharged into the atmosphere by the fan. The absorption liquid is sprayed down from the tower top after being pressurized by the water pump at the tower bottom, and then flows back to the tower bottom for recycling.

The storage tank is a new spiral wound disposable product with no welding cracks and better sealing performance. The thickness of PPH storage tank is not affected by the manufacturing materials. The external welding of PPH storage tank is a process that uses the imported automatic extrusion welding unit to make the large weld of the storage tank with high 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. Welding process characteristics of PPH storage tank bottom: 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; It can reduce flash, and the joints are smooth and beautiful.

Welding technology of PPH storage tank. In terms of automatic welding equipment and welding materials for large storage tanks, the degree of localization is not high enough, especially the automatic welding wire matching the imported high-strength steel plate, which still depends on imports and has high prices. This is a problem that China's PPH storage tank manufacturers must solve in the future; The research and application history of submerged arc automatic transverse welding for flip chip storage tank is not long, and there are still many problems to be solved; There is no doubt that CO2 semi-automatic gas shielded welding technology has obvious advantages over traditional shielded metal arc welding, but there are still many problems to be solved if this method is to be widely popularized and applied outdoors. First, the auxiliary equipment should be portable and flexible, and the wiring should have sufficient length. According to different weldments or parts, corresponding wind proof auxiliary devices shall be developed. It can be predicted that the development trend of welding technology of pph tank manufacturers will have a good application prospect in the welding fields such as petrochemical industry; Gas shielded welding with flux cored wire will be the development direction of large pph tank manufacturers. In the welding of low-temperature storage tank, automatic welding is beneficial to ensure the stability of low-temperature impact performance of heat affected zone.

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 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.
