Plasma-generating device, plasma surgical device, use of a plasma-generating device and method of generating a plasma

The present invention relates to a plasma-generating device comprising an anode, a cathode and an elongate plasma channel which extends substantially in the direction from said cathode to said anode. The plasma channel has a throttling portion which is arranged in said plasma channel between said cathode and an outlet opening arranged in said anode. Said throttling portion divides said plasma channel into a high pressure chamber, which is positioned on a side of the throttling portion closest to the cathode, and has a first maximum cross-sectional surface transversely to the longitudinal direction of the plasma channel, and a low pressure chamber, which opens into said anode and has a second maximum cross-sectional surface transversely to the longitudinal direction of the plasma channel, said throttling portion having a third cross-sectional surface transversely to the longitudinal direction of the plasma channel which is smaller than said first maximum cross-sectional surface and said second maximum cross-sectional surface. Moreover at least one intermediate electrode is arranged between said cathode and said throttling portion. The invention also relates to a plasma surgical device, use of such a plasma surgical device in surgery and a method of generating a plasma.

Method for coal bed methane mining by multi-element thermal fluid foam displacement

The invention discloses a method for coal bed methane mining by multi-element thermal fluid foam displacement. Multi-element thermal fluid is injected into a coal bed of an injection-production well group through an injection well, and foaming agent is injected at intervals. A multi-element thermal fluid foam slug is formed in the coal bed to displace the coal bed methane in order to improve the recovery efficiency of the coal bed methane. The method specifically includes that extracted coal bed methane is compressed and mixed with compressed air, and then the mixture is injected into a multi-element thermal fluid generation device for ignition, extracted processed ground water is mixed to produce the multi-element thermal fluid mainly with high-temperature and high-pressure water vapor and mixed gas of carbon dioxide and nitrogen, the produced multi-element thermal fluid is injected into the underground coal bed through the injection well, a foaming system composed of preferred alkyl ether sulfonate and corrosion inhibitor is injected from an oil jacket annulus at intervals, the multi-element thermal fluid foam slug is formed under the ground to displace the coal bed methane, and water is drained and gas is recovered from a production well. The method has the advantages that fuel is easy to obtain, principles are clear and distinct, and the like, and can provide guidance for implementation of well stimulation of the coal bed methane.

Long distance concentrated phase conveying system and method with auxiliary blowing apparatus

The invention relates to a long-distance dense-phase conveying system provided with an assistant blowing device and a method thereof. The conveying system comprises an air control apparatus formed by an air compressor, an air storage tank and a system control apparatus; a material storage bin and an on-line sub-bin which are formed by a material tank, a bin controller and a solid-air separator; a sending tank; a fluidization conveyor formed by a streamline casing, a guiding clapboard and an air inlet; a tube liner provided with air inlets arranged by an outer conveying pipe according to subsections and a dense-phase conveying pipeline formed by the assistant blowing device . The tube liner is fixedly connected with the inner upper wall of the outer conveying pipe; the assistant blowing device is fixedly connected and communicated with the outer pipe and tube liner. The dense-phase conveying method comprising the following steps: materials enters the sending tank from the material storage bin and then enters the dense-phase conveying pipeline through the fluidization conveyor and under the effect of compressed air to form a series of material plugs flowing in the conveying pipeline and finally the material reaches the sub-bin for processing and manufacturing. The invention has the advantages that the energy cost is low; the damage to material during the conveying process is less; the wearing to pipeline can be reduced; and the service life is long.

Instream hydro power generator

ActiveUS8506244B2Smoothly accelerate and redirect and decelerateReduces and minimizesPropellersRotary propellersCavitationWater flow
A turbine apparatus is immersed in an ambient stream of a flowing fluid, such as water, so as to encapture a portion of the flowing fluid and extract power therefrom, before returning it back into the ambient stream, which may be a tidal flow of ocean water, or a relative flow of water behind a boat. The apparatus includes a converging intake duct with an inlet opening that faces forward into the ambient stream flow, a spiral volute casing that redirects the fluid into a spiral flow, a rotor arranged coaxially on the spiral axis, and an exhaust duct that diverges and curves from an exhaust inlet coaxial with the spiral axis to an exhaust outlet that opens rearwardly into the ambient flow. The rotor has a peripheral rotor inlet around the circumference of a first stage thereof and an axial rotor outlet at one axial end thereof, and is arranged with its rotor axis coinciding with the spiral axis oriented transverse to the ambient stream flow. The rotor redirects the fluid from the spiral tangential and radial direction at the rotor inlet to the axial direction at the rotor outlet, while extracting power therefrom. Fluid flow channels are designed to achieve smooth acceleration, redirection, power transfer, and deceleration of the fluid preferably without turbulence and cavitation, and preferably using streamlines to develop the surface contours of complex channel components.
