摘要:
A wet electrostatic precipitator (ESP) is disclosed to have a housing, several discharge wires, two roughened collection electrodes coated with TiO2 or SiO2 nanoparticles, two porous metallic plates, and two roughened glass plates coated with TiO2 or SiO2 nanoparticles. The porous metallic plates and the glass plates coated with TiO2 or SiO2 nanoparticles located above the collection electrodes are used to enhance the uniformity of the water film. When particles are introduced into the ESP, they are charged by gas ions generated by corona discharge, and then migrate to collection electrodes due to electrostatic force. Finally, particles are removed by uniform water film flowing downward along the collection electrodes. Furthermore, pulse jet passing through the small holes on the collection plates is used to clean discharge wires, maintaining electric corona strength and prolonging the operation life.

A wet electrostatic precipitator is disclosed to include a condensation-growth chamber, a precipitation chamber connecting with the condensation-growth chamber, three dual-sleeve members mounted in the precipitation chamber, three discharge electrodes connecting with the dual-sleeve members, two insulating members covering on the inner surface of the precipitation chamber, and two ground electrodes mounted on the outside of the precipitation chamber. Thus, a uniform water film is formed on the surface of the insulating members to wash away the particles from waste gas. The condensation-growth chamber is provided for the particles to grow therein and thereby enhances the collection efficiency. The insulating member acts as a shield between the discharge electrodes and the ground electrodes and thereby avoids a short circuit or sparks.

This invention provides a high-efficiency parallel plate wet denuder (PPWD) for gas absorption, the absorption surfaces thereof are composed of two hydrophilic porous glass plates on which TiO2 particles are coated and subsequently are irradiated with UV light to form super-hydrophilic surfaces, so that it further enhances the formation of uniform water film and increases gas absorption efficiency. This invention can be used in the manual sampling devices for acidic/basic gases, the gas absorption equipments for acidic/basic gases and gas-particle denuder sampling devices, besides it can also be coupled with an ion chromatograph to make semi-continuous acidic/basic gas-particle monitors.

A magnetic field generating unit includes a first magnetic component, a second magnetic component, and a third magnetic component. The first magnetic component has a first magnetic pole, the second magnetic component surrounds the first magnetic component. The second magnetic component has a second magnetic pole facing the same direction as the first magnetic pole, and the first magnetic pole is opposite to the second magnetic pole. The third magnetic component surrounds the first magnetic component, and the third magnetic component is located between the first magnetic component and the second magnetic component. The third magnetic component has a third magnetic pole and a fourth magnetic pole, and the third magnetic pole is opposite to the fourth magnetic pole. The third magnetic pole faces the first magnetic component and the fourth magnetic pole faces the second magnetic component. The arrangement manner of the magnetic components may generate a uniform planar magnetic field.

摘要:
Enhanced paging mechanisms are proposed for Machine Type Communication (MTC) devices in 3GPP networks. First, adaptive paging is proposed to adaptively allocate extra paging occasions for MTC devices with no extra procedure or power consumption on normal UEs. Second, group paging is proposed to simultaneously page a plurality of MTC devices with one paging. Group paging is controlled in different levels for optimized signaling and easier management. In one embodiment, group broadcasting and group release are used. Third, paging with response policy is proposed to pre-define or dynamically configure paging response policies for MTC devices.
摘要:
A method of dynamic resource transaction in wireless OFDMA systems is proposed. In macro-femto overlay network architecture, network and traffic condition varies dynamically. Dynamic resource transaction is a powerful mechanism to achieve effective interference mitigation and flexible radio resource management to enhance resource utilization as well as to improve link performance. Dynamic resource transaction can be performed by signaling or message exchange through backhaul network or air-interface connections. The signal or message through backhaul network can be directly exchanged among multiple base stations or be routed through a centralized self-organizing network (SON) server. In one embodiment, dynamic resource transaction is used to achieve adaptive reservation region configuration, a solution to avoid interference and frequent handover for high-speed mobile stations.
