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.

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 key requirements of PPH tank design are: no danger, reliable: the data of high strength and toughness of materials, and the interchangeability structure of media should have sufficient rigidity and pressure bending performance, and the sealing performance should be good. Meet process request: function request of life request. Good comprehensive economy has high consumption efficiency, low consumption coefficient, reasonable structure, complicated manufacturing, convenient transportation and convenient equipment. Easy to operate, maintain and control: maintain and better control. Good environmental performance of PPH storage tank: At present, great progress has been made in the design scheme, engineering construction and data information of large and medium-sized storage tanks in China. However, our country still lacks experience in the design and construction of high strength data of large storage tanks. In the future, our country should strengthen the development and implementation of large storage tanks to make the production process of large storage tanks more carbon friendly.

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.

In the case of selecting the form of HDPE storage tank, it must still be determined according to the requirements, and it can perform well in terms of quality. Fortunately, superior product quality is certainly a basis for recognition. The better the product is, the more popular it will be. Its characteristics in all aspects are better, which is also a key to the requirements of industrial production and application. Products with good reputation will be more reassuring, so that they can be better in service level. If they are better in service level, they must be a basis for seeking good results, and then they can benefit from good product quality. Because there are many specifications of products, in order to meet the application requirements of different occasions, it is still necessary to select products based on actual requirements. In addition, HDPE tank repair can be made of polymer composite materials. The leakage test or hydraulic test shall be carried out after the bucket is repaired or replaced according to the internal and external inspection regulations.
