摘要:
A concentration difference photochemical reactor includes of a photochemical reaction tub and a photocatalyst reaction plate. The photocatalyst reaction plate is formed by combining in sequence a photocatalyst, a metal, a conductive carrier, and a reduction electrode to reduce its internal resistance barrier and increase the electron-hole separation rate excited by photons. By adjusting the concentration difference in the solutions inside the photochemical reaction tub, the location of chemical reactions is changed to increase the efficiency and reduce the use of a sacrificing reagent without the restrictions of thermodynamics.

摘要:
A plasma generating device, has a plurality of cavities shaped like half-ellipsoids, a plasma cavity, and microwave sources. The present invention takes advantage of geometrical properties of the propagation of electromagnetic waves by enclosing an electromagnetic field in the microwave range in overlapping cavities that together are shaped like a plurality of half ellipsoids. Each of the cavities has a first focus and a second focus, with the first foci of the cavities place close to each other. Microwaves entering the cavities at the second foci propagate inside the cavity and are focused at the first foci. The area around the first foci of both half ellipsoids forms a plasma cavity, providing a large volume filled with a microwave field. Thereby an increased volume of an electromagnetic field and thus of a plasma is achieved.
摘要:
The present invention provides a low power consumption desorption apparatus, which utilizes a pair of electrodes coupled to an absorbing material to provide an electric current flowing through the absorbing material so as to desorb the substances absorbed within the absorbing material. By means of the desorption apparatus of the present invention, the absorbing material is able to enhance the desorbing efficiency and reducing power consumption during desorption. The present invention further provides a dehumidifier using the low power consumption desorption apparatus for providing a continuous dry air flow to desorb and regenerate the moisture from the absorbing material so that the dehumidifier is capable of removing moisture in the air repeatedly to reduce the humidity.
