  • Patent number: 9931641
    Abstract: The present invention is an air purification method and device. Due to the lower airflow resistance that the present invention induces, an exhaust fan or blower with motor of lower torque is adopted. Consequently, the whole air purification is operated at a lower noise level. Lower operational voltage is applicable for the high-voltage electrostatic precipitator device and provides a similar or superior performance and effectiveness for dust removal. The air purification device/system is designed with higher flexibility and of more compact in dimension and size. Dust is removed from the environment by a high voltage electrostatic precipitator. The airflow stream within a high-voltage electrostatic precipitator is such that the direction of the path of the airflow is changed at least twice.

  • Patent number: 9895462
    Abstract: The present invention discloses an air purification apparatus. The air purification apparatus comprising: a casing which contains at least one apparatus air inlet and at least one apparatus air outlet; at least one main filter which is being installed at the apparatus air inlet and/or within the casing; at the periphery of the main filter, there locates a primary air flow inlet and a secondary air flow inlet. When a primary air flow is drawn to flow from the upstream to the downstream positions inside the casing, the primary air flow is adapted to pass by at least one edge of the exterior of the main filter, resulting at least two exterior surfaces of the main filter being exerted with different atmospheric pressures. Through the secondary air flow inlet, a secondary air flow is entrained through the main filter and flows from its exterior surface is exerted with higher atmospheric pressure to its exterior surface is exerted with lower atmospheric pressure.

  • Patent number: 9121837
    Abstract: The present invention is related to an environmental monitoring and analyzing device. The device contains a plurality of sensors, a control unit and a display unit. The different types of sensor obtain values of different environmental parameters. The control unit receives the obtained values of the environmental parameters and compares the obtained values against predetermined standards and criteria which define parameter ranges of the different environmental parameters. A display unit displays a real-time air quality report including a user-friendly interpretation of the obtained values and recommendations in response to the obtained values. By implementing this invention into an embodiment, the environmental monitoring analyzing is carried out instantly by considering the interrelationship of the obtained values of the different environmental parameters. The analyzed results are therefore much more accurate.
