Aeration blowers used in sewage treatment plants at home and abroad mainly include roots blower, multi-stage centrifugal blower, gear speed increasing single-stage high-speed centrifugal blower, air suspension centrifugal blower and magnetic suspension centrifugal blower. Among them, roots blower and multistage centrifugal blower have been phased out in foreign sewage treatment plants due to their low efficiency, high noise, high energy consumption, large volume and weight and poor flow regulation performance. Gear speed increasing single-stage high-speed centrifugal blower is widely used in sewage treatment plants at home and abroad because of its small volume, light weight, high efficiency, energy saving, wide range of performance regulation and high automation level.
Magnetic suspension single-stage centrifugal blower and air suspension single-stage centrifugal blower belong to the latest form of single-stage high-speed centrifugal blower. Due to the adoption of advanced frequency conversion speed regulation, magnetic suspension bearing and air suspension bearing technology, the gear speed increasing components and lubrication system of the traditional single-stage high-speed centrifugal blower are cancelled, which can meet the requirements of energy conservation, environmental protection, wide range of air volume regulation, low noise and The requirements of low vibration and low maintenance cost are one of the development trends of aeration blower in sewage treatment industry in the future.

Blowers in the chemical and pharmaceutical industry mainly play the following functions: first, as combustion supporting equipment, such as blowers used in sulfuric acid plants to blow air to burn sulfur or pyrite; Second, as oxidation equipment, such as air oxidation of organic waste in sewage treatment plants; It is used as aerobic fermentation equipment in penicillin production plant; Fourth, strengthen air convection. For example, workshops that produce waste gas use fans to blow in fresh air.
Blower plays an important role in smelting industry. The effect of oxygen on iron and steel industry lies in strengthening the smelting process, especially oxygen top blowing converter steelmaking has become a main way for the rapid development of iron and steel industry. The oxygen consumption of steelmaking is very large. It is obtained by deep freezing from the air using air separation equipment. Air compressor, oxygen compressor, heating blower and turbine expander must be used in each set of oxygen generator, which is commonly known as the "four oxygen generators". The steady growth of metallurgical industry will bring good development prospects to the blower Market.
In the production of electric power, metallurgy and other industries, in order to remove the sulfur element in coal and prevent the sulfur dioxide generated during combustion from entering the air pollution environment, the flue gas after combustion is usually collected by flue gas desulfurization and desulfurized by gypsum wet process. The blower is mainly responsible for air supply and oxidation in the flue gas desulfurization process. It is necessary to ensure that the blower can provide sufficient oxygen in the process. For example, insufficient air volume will lead to insufficient oxidation, low quality of by-products, incomplete desulfurization, etc.
At present, "energy conservation and consumption reduction" is the development direction of the cement industry. The state's attention to energy conservation and emission reduction has brought many pressures to cement enterprises with high energy consumption and high pollution, forcing cement enterprises to update cement production equipment and develop in the direction of energy conservation and environmental protection. Cement enterprises have begun to actively carry out technical transformation with the help of new energy-saving production equipment. Fan is one of the important equipment for power consumption in cement industry. The cement industry is a high energy consuming industry. Driven by market demand, the policy of eliminating backward production capacity, the needs of enterprises' own market competition and the progress of cement production technology and equipment, the production mode of new dry process cement has been vigorously promoted and applied. Therefore, promoting the upgrading of blowers is an important way for the cement industry to save energy and reduce consumption. The opportunity of eliminating a large number of backward production capacity and fixed assets in the cement industry.
