Introduction to typical uses of Roots fans (II)

  • When unloading ash from the gas power plant ash bank (or ash hopper), in order to prevent the caking of coal ash, the compressed air discharged from the blower is usually heated and dried and sent to the gasification tank at the bottom of the ash bank or ash hopper, so that the coal ash attached to the surface of the gasification plate is fluidized and easily flows out of the ash unloading port. Unloading from the cement depot has a similar application.
  • Use the hose suction head to clean the dust on the pot body and platform, and the air after removing the dust is pumped out by the vacuum pump. In addition to stationary vacuum trucks to clean all kinds of loose material and dust.
  • In some large-scale fish and shrimp farms, blowers are usually utilized to drum air into the breeding tanks in order to increase the dissolved content of oxygen in the water, accelerate the oxidative decomposition of certain harmful substances, contribute to the purification of water quality, and promote the growth of fish and shrimp. Similar devices are also used for oxygenation and mixing in aquariums and live fish tanks.
  • In the gas-solid two-phase contact of chemical reaction, the solid particles are placed on the air cloth plate, and the compressed air provided by the blower is utilized to make the particulate material float and fluidize, and make full contact with other reactants or catalysts, which can improve the speed and efficiency of the reaction. For example, the use of nai to produce phthalic anhydride, the roasting of sulfurous iron ore to produce sulfur dioxide and so on.
