One micron to several hundred micron large. The other is a gaseous pollutant, such as a gas, such as a odor, a volatile organic chemical, etc., which has a simple chemical structure, is composed of a variety of chemical elements, and is very small, only the size of the Amy to the nanometer. .

  • Air with contaminants also has a method of electrostatically removing dust generated by high voltage, or discharging negative ions to make negatively charged dust particles suspended in the air, and then collecting them in a neutral or positive charge.
  • Activated carbon, molecular sieves, zeolites are also used as filter materials, or ozone, oxidants, ultraviolet lamps, and photocatalysts or different catalytic catalysts are used to oxidatively catalyze the decomposition of pollutants.
  • filter elements used are arranged in such a way that the filters are arranged in parallel one after another in parallel with the inlet and outlet ports, and only one exhaust fan or blower is provided to drive the air flow from upstream to downstream.
  • filters have different physical and chemical characteristics, there are ways to use filtration, there are ways to use adsorption, and there are ways to use ionization. Some filters have large wind resistance and some have less wind resistance. A filter with a large wind resistance or a filter with a higher density generally has a very superior filtering effect, and also has a large accommodation capacity when filtering pollution.
  • fans such as electric fans, dehumidifiers, humidifiers, and cooling fans. Air conditioners, heaters, etc.
  • These electrical devices with fans have their own functions. Because the motors of these fans have different torques, it is impossible for these electrical devices to be used with filters with different wind resistance. Adding filters will increase the fan. The load on the motor may cause the fan motor of these electrical devices to overheat or even burn out.
  • the multiple electrical devices containing the fan are placed in one place not only occupying space, but also completely utilizing repeated components such as motor fans, etc., also causing a waste and not being environmentally friendly.
  • air ventilation devices or environmental devices which use a fanless fan (an electric fan without a fan fan) as a means for circulating air in the room.

  • the device can be converted into an air filter device by adding a filter. Because these airless amplifiers designed with no fan blades rely mainly on two air flow paths to achieve ventilation.
  • One of the paths is a high-pressure air (first air flow) 96 by a high-torque, high-pressure motor 91. This air flow path flows in the casing.
  • a filter 94 is added to the air 96 flow path, The pressure of the air 96 flowing in the housing is weakened, and the low pressure air is sent out from the venturi nozzle 92, The effect of pulling the surrounding air 97 can be achieved.
  • Another air flow path is a wall-attaching effect of the hollow circular casing, and the surrounding air (second air flow) 97 flows through the hollow casing. If a filter 95 is added to the air flow path, The appearance of the hollow circular casing is changed. Thus, the Coanda effect will disappear due to the change in appearance, and the surrounding air 97 will not be pulled and flowed.
