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.

What are the anti-corrosion treatment of PPH storage tank? For PPH storage tanks storing oil and product oil, since the performance required by the anti-corrosion materials in PPH storage tanks is electrostatic conduction, all PPH storage tanks shall be subject to anti-corrosion treatment with electrostatic conduction coating. The treatment of the external anti-corrosion coating of the tank is a comprehensive treatment that takes into account the anti-corrosion performance, weather resistance and aesthetic performance of the tank. In the design of anti-corrosion coating for PPH storage tank, it is necessary to consider that each anti-corrosion coating has temperature resistance and compatibility. If the alkyd anti-corrosion coating is used, it is necessary to avoid direct matching, because it will react with zinc powder. The cathodic corrosion protection of the tank is divided into impressed current cathodic protection on the outside of the bottom plate of the tank, and protective treatment on the anode of the ponding layer in the tank.

The small softening point of PPH storage tank is 108 ℃, and the large fragmentation point is - 70 ℃, so PP storage tank can generally be used to hold liquid with temperature ranging from - 40 ℃ to 60 ℃. The feed inlet, discharge outlet, liquid level gauge outlet, flange, etc. on the PPH storage tank body are all integrally formed and welded at one time, without additional feed inlet and outlet. When containing acid-base substances, acid-base resistant gaskets shall be provided. When organic substances (especially organic solvents) are contained, insoluble rubber gaskets shall be provided. PPH storage tank is made of polypropylene, which can contain inorganic acids, malic acid, salts, ammonium, alkalis, oils and most gaseous organic substances at normal temperature and pressure. PPH storage tank cannot be used to contain strong oxidants, such as concentrated sulfuric acid, concentrated nitric acid, etc. When using PPH storage tank, we should not forget that it is just a tool we use. If the tool is not used properly, it will also break down. Therefore, why we use PPH storage tank with different life depends on how we treat them.

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.

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 use of PPH storage tank, the process of reaction material mainly depends on the change of storage tank temperature to realize the reaction. When designing PPH storage tank, its pressure and temperature should be standardized. The pressure here refers to the gauge pressure unless otherwise specified. Working pressure refers to the possible high pressure at the top of the container during normal operation. Design pressure: the pressure used to determine the shell thickness at the corresponding design temperature. 1.05 times the high working pressure shall be taken for the internal pressure vessel, and the static pressure of the liquid shall be included. The design pressure of external pressure vessel shall not be less than the possible large internal and external pressure difference under normal operation; Test pressure: refers to the pressure at the top of the vessel under pressure test; The vacuum vessel is designed according to the external pressure. When a safety control device (such as a vacuum relief valve) is installed, the design pressure is taken as the smaller value of 1.25 times the internal and external pressure difference or 0.1MPa, or 0.1MPa if there is no safety control device.
