Roots Blower Because of the universality and applicability of the application field, it is classified in the category of general machinery. The assembly and use conditions of Roots blower are very simple, but in different fields, the use methods of Roots blower are different. The author followed up and discussed this issue with relevant personnel of Jinan Xushi Precision Machinery Co., Ltd. for a long time, and summarized the following usage methods for your reference in different fields: (1) Sewage treatment
Municipal sewage project is what we usually call a sewage treatment plant with a wide distribution. The main purpose of Roots blower is to supply oxygen for aeration. The primary purpose is to provide oxygen supply and flow for the reaction bacteria in the biochemical tank, ensure the normal survival of the bacteria, so as to remove harmful and reactive substances in the sewage through the bacteria, Provide a good environment for the next step of sedimentation and other treatment. This type of Roots blower usually supplies dozens or even hundreds of ponds through the main pipeline, so it generally requires large flow and long operation time, which puts forward strict requirements for the operation of Roots blower itself. The author has learned that many manufacturers, such as the double oil tank and low-noise fan produced by Jinan Xushi Precision Machinery Co., Ltd., can better meet the user's requirements, and have excellent functions of maintenance free and low noise, which are suitable for various large, medium and small sewage projects.
Because of the structure problem of Roots blower itself, the noise value is relatively high. Many water purification systems are usually located indoors or in urban areas, and Roots blower is often replaced by such users. However, Roots blower is still widely used in suburban and noise controlled water purification projects, Compared with other types of oxygen supply fans, Roots blower has the advantages of large flow and stable air supply, and is also suitable for this type of system.
(3) Desulfurization and denitration
Flue gas treatment, desulfurization and denitrification, power plant dust removal and other systems are used more often. The operation of desulfurization and denitrification system is also handled in the reaction tower or reaction pool by means of pipeline air supply. The use of this type of Roots blower is generally characterized by large scale, large model and high pressure. Therefore, in terms of model selection, large air volume and large pressure, more than 200 models, bipolar series connection and high-pressure water cooling have become the best choice for users. The price and quality of products in the market vary, so it is important to select a stable and reliable manufacturer with relevant qualifications and technology accumulation.
(4) Pneumatic conveying Strictly speaking, the above desulfurization and denitrification can also be placed in the field of pneumatic conveying. The reason why it is taken out separately as a system is the particularity of desulfurization and denitrification. In general, for pneumatic conveying system, Roots blower is always the air source provider, so the Roots blower combined with pneumatic conveying has the characteristics of large pressure at the moment of starting, large air volume at starting, many use gaps, high pipeline pressure, and long general conveying distance. Therefore, when selecting Roots fan, it is necessary to select a fan with good heat resistance, stable bearing performance, and the ability to adapt to repeated startup and low natural loss of the fan.
