High-efficiency and energy-saving multifunctional centrifugal blower fan

Abstract

The invention discloses a multifunctional centrifugal blower with high efficiency and energy saving, which comprises a shell, an impeller, an impeller chamber, an gas spin chamber, an air inlet, an air outlet and a motor, wherein, the impeller consists of at least one group of arc-shaped channel vanes closed at one side and amplified axially; the shell is internally provided with a round dual chamber or multi-chamber provided with the air inlet and the air outlet. The efficiency of the centrifugal blower is over 80 percent, the energy is saved by more than 10 percent while the noise is lower than 80dB; the impeller is not easy to wear basically and the material is saved by more than one second; also the centrifugal blower has various functions such as ventilation, air supply, air inducing, smoke exhaust, and material absorption and discharge, etc. The comprehensive economic and technical indexes of the centrifugal blower achieve the leading level both at home and abroad, the energy saving effect, the exhaust reduction effect and the economic and social benefits are remarkable.

Description

technical field [0001] The invention is a high-efficiency energy-saving multifunctional centrifugal fan, which belongs to the field of energy-saving equipment manufacturing and automation. Background technique [0002] As we all know, fans are mechanical products with a wide range of uses, large batches, and high energy consumption. From a discipline point of view, fan is the application and development of fluid mechanics. In a thermal power plant, the fan is an important part of the power cycle and one of the important auxiliary machines. The safe and economical operation of wind turbines plays an important role in the safe and economical power generation of power plants. From the perspective of energy, the fan is a type of fluid machinery that can convert the mechanical energy of the prime mover into the pressure potential energy and kinetic energy of the conveyed fluid. Fans are widely used in various sectors of the national economy, such as the ventilation of tunnels ...

AI Technical Summary

Problems solved by technology

However, in terms of the actual application of fans, relevant statistics show that the actual operating efficiency of our country’s running fans is 30% lower than the international advanced level. Low efficiency and serious waste of energy

Although many scholars at home and abroad have carried out long-term and arduous research and achieved certain results, but looking at various research results, they have not jumped out of the traditional theoretical framework of using rotating impellers for energy transfer. Therefore, in improving efficiency, reducing energy consumption, In terms of noise reduction and life extension, although there have been improvements and improvements, no breakthroughs have been made
