The vertical kiln calcination and air supply in the cement industry uses a vertical kiln for cement calcination, which has the characteristics of low thermal consumption, low investment, and high efficiency. Positive displacement Roots blowers are widely used for air supply in cement calcination due to their hard exhaust characteristics and pressure self-adaptivity. For the cement vertical kiln, the required air pressure often changes due to changes in the height of the material layer in the kiln. As the material layer height increases, the required air pressure also increases, and a positive displacement Roots blower can well meet this requirement due to its hard exhaust characteristics.

Application in Iron and Casting Industry:

Medium and small blast furnaces and cupolas require Roots blowers for air supply. Positive displacement Roots blowers have become key equipment in metallurgical and casting plants due to their advantages of high pressure, stable performance, and reliable use compared with high-pressure centrifugal fans.

Application in Chemical Industry:

In the chemical industry, positive displacement Roots blowers are used to transport sulfur dioxide in sulfuric acid plants and nitrous fumes in explosives factories.

Application in Urban Gas Industry:

With the development of urban construction, gas pipelines have gradually entered thousands of households. Positive displacement Roots blowers can be used in various occasions due to their high pressure and good air tightness.

Application in Sewage Treatment Industry:

Positive displacement Roots blowers are used in sewage treatment plants for biochemical reaction aeration. When selecting a blower, the air pressure depends on the water depth, pipeline resistance, and water viscosity, and the air volume depends on the water volume.

Application in Aquaculture Industry:

Positive displacement Roots blowers are widely used in aquaculture due to their maximum common air supply, suitable pressure, and non-polluting output gas. In addition to increasing the dissolved oxygen content in water, they can also accelerate the oxidation and decomposition of certain harmful substances in water, which is important for purifying water quality. For shrimp seed breeding, the air supply rate per minute should reach at least 1.59% of the total water volume.

Large-scale thermal power plants use positive displacement Roots blowers, mainly for 300,000 kW thermal power generator sets, using negative pressure ash discharge hoppers and ash silo gasification blowers, which can agitate the ash to increase its fluidity.
