摘要:
A fast heat transfer device is provided. The device dissipates heat and generates power at the same time. A liquid flow is used to absorb heat for forming a vapor gas flow; then, the gas flow drives a blade turbine and a power generator; and, finally, the gas flow is cooled down to become the original liquid flow for recycling. Thus, the present invention dissipates heat and generates power simultaneously with a minimized size and a reduced cost together with energy conservation.

A DC steam plasma torch includes front, middle and rear sections. The front section includes a first amount and a first electrode attached to the first amount, thus defining co-axial first internal and external coolant channels. The middle section includes a second mount and a second electrode co-axially connected to the second mount, thus defining co-axial second internal and external coolant channels. The rear section includes an insulating transient element connected to the second electrode, a window frame connected to the insulating transient element and a window provided in the window frame. A first swirl generator is provided between the first and second sections to receive primary working gas and generating a swirl in the same. A second swirl generator is provided between the middle and rear sections to receive auxiliary working gas and generating a swirl in the same.

A dynamically real-time adaptive trommel screen system is revealed. The dynamically adaptive trommel screen system includes a fixture, a trommel screen disposed on the fixture for screening a mixture into regenerated filter granules and screened residues, a structured duct for transporting the regenerated filter granules and an enclosure for collecting the screened residues, a tilt control member arranged on the fixture for adjusting the tilt angle of the trommel screen, and a feedback controller that controls the tilt control member according to the mass flow rate of the screened residues when the trommel screen operates so as to adjust the tilt angle of the trommel screen instantly and dynamically. By the feedback controller and the tilt control member, the tilt angle of the trommel screen is adjusted in a real-time and dynamic way so as to increase the screening efficiency. Moreover, the state of fractured filter granules is acquired from the feedback controller so that a certain amount of fresh filter granules can be refilled into the filter system for improving the filtration efficiency.

The present invention is an AC/DC (alternating current to direct current) converter. The converter contains two semi-stages. One is the boost-flyback semi-stage that has excellent self-PFC property when operating in DCM even though the boost output is close to the peak value of the line voltage. Moreover, it allows part input power transferred to load directly through the flyback path so the power conversion efficiency is improved. The other one is the D/DC semi-stage that provides another parallel power flow path and improves the regulation speed.

The present invention provides a plasma torch device. The device comprises a front electrode, a back electrode and a vortex flow generator. The torch roots of the back electrode are moved by fixed magnets. By controlling the magnets coordinated with vortex air flow, the torch roots are moved back and forth periodically on inner surface of the back electrode. The torch roots do not stay at the same place for long for preventing increasing local heat burden of the electrode. Thus, life time and maintenance cycle of the electrode is prolonged with reduced operational cost of plasma torch and enhanced reliability of the device.

Incinerator ashes, which is obtained after treating municipal solid waste, incinerator ashes or its plasma vitrified slag is made into mineral fibers. Cullet is added during manufacturing the mineral fibers for conditioning. The mineral fibers thus obtained have a good strength and could raise value of recycled product. In addition, it could reduce impact of the incinerator ashes to the environment and environmental protection is achieved.

Disclosed is a method for making a refractory material from aluminum residues of aluminum recycling. At first, the aluminum residues is mixed with adhesive solution so that the percentage by weight of the adhesive solution is 5 wt % to 10 wt %. The mixture is granulated into grains. The grains are filled in a mold, pressed and then removed from the mold so that the grains are turned into a green body. The green body is heated in a furnace at a range of temperature from 1100° C. to 1400° C. so that the grains are sintered and become a refractory material.
