Roots blower

Roots blower: application areas and comprehensive introduction

Roots blower, as a volumetric fan, has been widely used in multiple industries due to its unique structure and working principle. This article will provide a detailed introduction to Roots blower and explore its applications in different fields.

1、 Introduction to Roots blower

Roots blower mainly consists of five parts: casing, wall panel, impeller, oil tank, and muffler. Its working principle is to rotate two three bladed impellers relative to each other in a space sealed by the casing and wall panel, forming a continuous process of intake, compression, and exhaust. This structure reduces the vibration and noise of the Roots blower during operation. At the same time, its impeller and shaft are an integral structure without wear, ensuring the long-lasting stability of the fan performance.

Roots blower has various advantages, such as simple structure, convenient manufacturing, clean air delivery, and long service life. In addition, due to the use of a three blade rotor structure and a reasonable structure at the inlet and outlet of the shell, the Roots blower performs well in gas conveying and pressurization systems, especially suitable for low pressure situations.

2、 Roots blower application field

Chemical industry: In chemical processes, Roots blowers are used for various tasks, such as conveying chemical raw materials, conveying reaction gases, aeration and stirring, sewage treatment, ventilation and exhaust, gas pressurization, and pulse dust removal. These applications all involve the pneumatic conveying performance provided by Roots blowers.

Wastewater treatment industry: The wastewater treatment industry is one of the main application areas of Roots blowers. In the process of sewage treatment, oxygen needs to be injected into the sewage tank to promote the oxidation synthesis process of microorganisms. Roots blower can provide quantitative oxygen according to different water depths, promote microbial growth, and help decompose suspended solids and organic compounds in wastewater.

Aquaculture industry: In the field of aquaculture, Roots blowers are widely used for oxygenation and aeration. By installing an aeration tray at the bottom of the water tank and connecting a Roots blower, oxygen can be regularly supplied to the water, increasing the oxygen content in the water and helping aquaculture enterprises increase production.

Desulfurization and oxidation: Roots blower plays an important role in the desulfurization and oxidation process in industries such as thermal power plants. By treating pollutants such as sulfur dioxide in smoke and dust gases, environmental pollution is reduced and ecological environment is protected.

Powder conveying: Roots blower is also widely used in the field of powder conveying. Although the Roots blower itself cannot transport gases containing a large amount of solid media, it can transport clean air and cooperate with other equipment to achieve the transportation of powdered materials. In addition, in pneumatic conveying systems, Roots blowers are also used for the transportation of powdered materials such as feed, lime powder, monosodium glutamate (MSG), soybean husks, and silica.

3、 Summary

Roots blower, as an efficient and stable gas conveying equipment, has been widely used in multiple industries. Its unique structure and working principle make Roots blower perform well in gas conveying and pressurization systems, especially in low pressure situations with significant advantages. With the continuous progress of technology and the rapid development of industry, the application fields of Roots blower will continue to expand, providing more reliable gas transportation solutions for various industries.
