1. Anodic protection stainless steel concentrated sulfuric acid cooler: anodic protection technology is to form a dense oxide film on the metal surface to prevent further corrosion. For the concentrated sulfuric acid cooler, this means that the metal material inside the cooler can be effectively protected, extending the service life of the equipment. The shell-and-tube design allows for more efficient cooling and is easy to monitor and maintain. Its working principle is to use the cooling medium (usually water) in the tube to cool down the concentrated sulfuric acid outside the tube.

2. Anodic protection stainless steel concentrated sulphuric acid distributor, anodic protection concentrated sulphuric acid pipe-trough type acid distributor system has tube type, trough type, trough type and other forms for users to choose, the annual corrosion rate is only 0.01-0.03 mm/A, the acid point is less than 45 points/m ~ 2, and the packing height is effectively reduced. Free ventilation area is large, non-clogging, less entrainment of acid foam, large flexibility of operation. No daily spare parts and maintenance costs. The stainless steel acid divider with anode protection of dry absorption tower in our company is a tank-and-tube type acid divider and a tube type static pressure overflow type acid divider, which is mainly composed of acid divider, acid divider tank and anode protection system.

3. Anodic protection system. When a metal is immersed in an electrolyte solution, a potential is established between the surface of the metal and the solution. The potential of different metals in a given solution is different, and the same metal, due to the existence of electrochemical inhomogeneity between its parts, produces a certain potential difference between different parts, it is this potential difference that leads to the electrochemical corrosion of metals in electrolyte solutions. When a direct current is applied to a metal immersed in an electrolyte solution, the natural corrosion potential of the metal changes, a phenomenon known as polarization. When the current is positive, the potential of the metal as an anode changes in a positive direction is called anodic polarization, whereas when the current is negative, the process by which a metal acts as a cathode and its potential changes in the negative direction is called cathodic polarization. When the metal with the tendency of passivation is anodized, if the current reaches enough value, a passivation film with high corrosion resistance can be formed on the surface of the metal, this passivation can be maintained by continuing to apply a small current, the passivation metal surface solution is very small to prevent metal corrosion, this is the basic principle of anodic protection.

A sulfur trioxide evaporator is a heat exchanger that uses a heat source (steam or flue gas) to sulfur trioxide free SO3 from high concentrations of niacin (free SO3 concentration greater than or equal to 25%) . The structure has horizontal u-tube and vertical straight tube, usually steam heating using horizontal, gas heating using vertical (of course, vertical can also be heated by steam) , the company holds 3 utility model patent certificates for this product.

Second, development and application, our company is an important promoter of the technology, not only for the above product research and development and design, but also responsible for manufacturing and engineering services.

3. Product value and social benefit, anodic protection concentrated sulphuric acid cooler is widely used in sulphuric acid production field because of its high cooling effect, long-term durability and low maintenance cost.
