An air sterilization device with low aerosol bounce includes an air conditioning pipe, a porous filter media, and a UV light generator. This porous filter media, it is secured on the fixing portion. This porous filter media has many irregularly distributed channels. The channel is coated with a coating layer having a thickness between 10 &#x3bc;m to 1000 &#x3bc;m sticking aerosols for avoiding bounce effect. The UV light generator can emit UV light to kill biological aerosols. It is suitable for long-term usage. So, the bounce effect of aerosols can be significantly reduced. The maintenance cost is low. The sterilization effect is excellent. Plus, the flow rate of the air conditioning system remains high.

Air sterilization device with low aerosol bounce

The present invention is a push-pull ventilation hood having a push device to obtain a push air flow and a pull device to exhaust contaminant flow with an exhaust opening and the two devices properly coordinated with each other, wherein, when the push flow flows through a contaminant source, a contaminated flow of the push flow is exhausted through the exhaust opening. Based on the design process according to the present invention, a push-pull hood with the highest efficiency of push velocity can be designed and the push-pull hood can economically and effectively control the contaminant source.

Push-pull type ventilation hood

An air curtain-assisted exhaust method and a device thereof are provided. Air curtain generators are disposed on a worktable to enclose an encircled area in the worktable. A receiving hood is disposed above the worktable, wherein the vertical lower part of the outer edge of the receiving hood completely covers the encircled area. Then, the air curtain generators are started to blow out air curtains toward an opening of the receiving hood, and the receiving hood is started to suck an air flow. A shielding space is defined by the air flow sucked by the receiving hood and the air curtains, so that the air curtains may guide a smoke generated inside the shielding space to the receiving hood to be exhausted, thereby achieving the effect of auxiliary exhaust, and may restrict the smoke in the shielding space to prevent the smoke from diffusing laterally.

Air curtain-assisted exhaust method and device thereof

The present invention is a fume hood capable of exhausting contaminant, having an air pipe in a sash and a suction slot corresponding to the air pipe deposed at the front rim of the bottom surface to obtain an air curtain, where contaminant is efficiently prevented from leakage and energy is saved.
