1、 Sulfuric acid heater [Sulfuric acid heat exchanger] Main purpose
  ·Sulfuric acid heater is also called sulfuric acid heating equipment or sulfuric acid heat exchanger. Its super corrosion and anti-aging performance makes it widely used in chemical industry, pickling, electroplating, medicine, anodizing and other industries. At the same time, because of its temperature resistance * *, it is suitable for both steam heating and hot water heating.
2、 Basic introduction of sulfuric acid heater [sulfuric acid heat exchanger]
  · teflon The full English name of plastics is Polytetrafluoroethylene, which is called Teflon, PTFE, F4, etc. for short; Chinese name“ Plastic King ”、“ Teflon ”、“ Teflon ”, "Teflon", etc. It has unparalleled chemical stability and cold and hot stability (- 250~260 ℃). Sulfuric acid heater tube sheet And tube bundle (φ 3-10mm capillary ）Advanced powder metallurgy It is made by sintering technology and has excellent properties.
  
  ·There are many types of sulfuric acid heaters, including immersion heaters in the shapes of W, L, U, O, flat and surround Heat exchanger , as well as tower heat exchanger and shell and tube heat exchanger, in which tower heat exchanger and shell and tube heat exchanger (also called shell Tubular heat exchanger ）According to different heat exchange processes and heat exchange media, the shell of the can be made of metal materials or polymer materials; ·The unique and advanced welding method is adopted to make the connection strength between the tube bundle and the tube plate of the sulfuric acid heater equipment reach 1.5 Mpa， It solves the problem that the traditional welding method of fluoroplastic heat exchanger has micro leakage and needs leakage pipe. Through combination, the sulfuric acid heater can be made into various forms, which is an ideal choice for heat transfer of strong corrosive, strong acid and strong oxidizing media, and is popular with users;
  ·The sulfuric acid heater can be used for steam heating, hot water heating or cold water cooling. It is suitable for heating, water cooling, refrigeration, evaporation concentration and seawater cooling of electroplating, electrolysis, phosphating, pickling, aluminum polishing, degreasing, anodic oxidation and other surface treatment processes;
  The working pressure, working temperature, heat transfer coefficient and installation method of sulfuric acid heater vary greatly according to different types, tube shell materials and heat medium. Our company selects * * reasonable and * * economical design scheme according to the user's actual working conditions to * * meet the user's use requirements to a large extent.
Main features of trisulfuric acid heater [sulfuric acid heat exchanger]
  ·Sulfuric acid heater has excellent corrosion resistance: F4 is a chemical inert material, which can work in all media except element fluorine, molten alkali metal, chlorine trifluoride, uranium hexafluoride and perfluorocarbon under high temperature. Such as: various strong acids and bases, sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, sodium hypochlorite, naphthalene, benzene, xylene, acetone, aqua regia, chlorine, toluene, various organic solvents, etc;
  ·Sulfuric acid heater equipment has good anti scaling performance: F4 pipe's chemical inertia, surface smoothness, curvature and high expansion coefficient make it difficult to scale its heat transfer surface, ensuring a relatively stable heat transfer coefficient;
  
  ·The sulfuric acid heater has good heat transfer performance: due to its small pipe diameter, no temperature difference gradient, and thin wall tubes, it overcomes the shortcomings of low thermal conductivity of polytetrafluoroethylene material, so that its total heat transfer coefficient can reach 200-350 (W/m2. K);

·Long service life and low comprehensive cost of sulfuric acid heater: Teflon has no photosensitive gene, so it has excellent resistance to atmospheric aging. Its service life in strong corrosive media is 20 to 30 times that of stainless steel. In addition, our company has thoroughly solved the problems such as easy to hang up in use in the past, which has greatly increased its service life;
·Small resistance of sulfuric acid heater: due to the small friction coefficient, low roughness and excellent lubrication performance of F4, the resistance of fluid in the tube bundle is smaller than that of metal tube.
