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.

Working principle of PPH waste gas purification tower: there are multi-stage packing rings inside. During operation, waste gas flows upward from the bottom. Due to tangential entry into the tower, especially the guiding role of the packing layer, the rising flue gas rotates, resulting in good contact between the packing layer and the pollutants in the waste gas and the liquid, which has a large contact area between the gas and the liquid; The droplets will also rotate through the air flow, and the centrifugal force generated will enhance the gas contact at night. After being thrown to the tower wall, the liquid drops will flow down the wall and reach the next layer of packing through the overflow device. The nozzle will atomize again to contact with gas and liquid. The liquid can be effectively separated after full contact with the gas, and the dust particles in the gas will be removed by adhering the water mist to the filler layer. In addition, dust and fog drops will be thrown onto the tower wall under the action of centrifugal force, and flow to the bottom of the tower to be removed, thus reducing the possibility of dust and fog drops brought by air flow from the tower.

PPH storage tank has good temperature resistance, acid and alkali resistance, high strength and impact resistance, longer service life, and no environmental stress fracture damage. At present, the tank has become a necessary equipment for chemical industry, smelting, rare earth, mining, pigment, printing and dyeing, new materials, new energy, and biomedicine. In the next few years, PPH storage tanks will be widely used. Manufacturing process of PPH storage tank: extruding and winding PPH granular materials. The product is formed at one time without welding. PPH tank is welded by polypropylene plate. In terms of corrosion resistance, PPH vertical storage tank and PH vertical storage tank have similar corrosion resistance. From the perspective of safety performance, the PPH tank shell is integrally formed without welding and leakage, while the PPH tank is welded, which is easy to cause leakage and increase unsafe factors. There is a big gap between the other two properties, such as aging resistance.

The anti-corrosion means of PPH storage tank are cathodic protection and coating protection. Coating protection can be divided into two ways, namely, internal anti-corrosion treatment and external anti-corrosion treatment of PPH storage tank. For oil storage or product oil storage tanks, the required performance of anti-corrosion coating in the tank is electrostatic conduction. Therefore, in the process of anti-corrosion treatment of storage tanks, electrostatic conductive coatings are used for anti-corrosion treatment of storage tanks. The treatment of anti-corrosion coating outside the tank is to combine the anti-corrosion performance, weather resistance and aesthetic performance of the tank. In the design of anti-corrosion coating for PPH tank, the temperature resistance characteristics between anti-corrosion coatings must be considered, which is interchangeable. In the alkyd anti-corrosion coating, direct combination use must be avoided. This is because of chemical reaction with zinc powder. Cathodic corrosion protection of storage tank includes impressed current cathodic protection of storage tank bottom plate and protection treatment of storage tank ponding layer anode. Cathodic corrosion protection of storage tank is divided into impressed current cathodic protection on the outside of the bottom plate of the storage tank, and protective treatment on the anode of the ponding layer in the tank.
