Shell and tube heat exchangers are mainly used for sulphuric acid production from minerals, sulphur-burning sulphuric acid, smelting flue gas sulphuric acid production, gypsum sulphuric acid production, hydrogen sulfide acid gas sulphuric acid production, waste sulfuric acid Heat exchange and air preheating of reformed gas in various sulphuric acid plants such as regeneration and steel plant analysis gas sulphuric acid plants.
At present, our company’s shell-and-tube heat exchanger products cover 5-800kt/a sulphuric acid plants, and realize the diversification of design forms to cope with different working conditions. Types of requirements: If divided by the form of heat exchange tubes, shell-and-tube heat exchangers mainly include smooth tubes and convergent tubes; they are distinguished by gas baffle devices on the shell side, such as disc ring type, single circle type, and double Design forms such as round-cut type and longitudinal scouring of heat exchange tube with spoiler device. In addition, depending on the scale of the sulphuric acid plant, the gas flow channel in the shell side is designed in single-channel, dual-channel and multi-channel styles. And use different materials to adapt to the corresponding media.
For each of your cases, we are tailor-made, professionally designed, not applied, not rigid; in the processing process, we strive for perfection, so as to make the product quality superior. You vote for me to trust, and I repay with meticulous products and services.
