Two-stage sulfur dioxide low-speed high-pressure fan award
Fixed tube heat exchanger consists of tube bundle, tube plate, shell, head, folded plate, etc. Tube bundle ends fixed in the tube plate, the tube can be expanded (the inner hole of the tube with mechanical expansion, so that the tube wall from the inward to outward extrusion and fixed in the tube plate) or welded to the tube plate. The tube bundle is placed within the tube shell, with headers and flanges fixed at both ends. In this way, one fluid flows from the inside of the tube and the other from the outside. The space between the two heads and the tube plate is used to distribute or collect the fluids inside the tube. The two fluids do not mix with each other, but only exchange heat through the tube wall.
Advantages: simple and compact structure, high pressure resistance, low cost and easy to clean the tube side.
Disadvantages: Risk of blockage when the tube is damaged or needs to be replaced.
When the difference between the wall temperature of the tube bundle and the shell or the coefficient of linear expansion of the material is large, a large thermal stress will be generated in the shell and the tube bundle. A flexible compensation ring (also called expansion joint) should be installed on the shell to reduce the thermal stress.

The fan is developed for high pressure requirements of the acid production process in the highland areas of western China or in the plain areas, and is mainly used for transporting acid-sulphur dioxide gas. The heart of the impeller is designed to be two-stage compression, which solves the two major problems of compression ratio, corrosion of the sulfuric acid, and strong adhesion that affect product quality.
The fan has the advantages of low rotation speed, comparable compression ratio, simple structure, convenient operation and maintenance, long service life, etc. It is an ideal product suitable for high-pressure acid production process in high altitude areas.
