The invention relates to a device and a process for homogenizing a fabric dust collecting electrode surface water film for a wet electrostatic dust collector / demister. The device comprises a shell, a guide vane, a discharge electrode fixing device, a discharge electrode, a dust collecting electrode square tube, an insulated case, a support device, a film distributing device, a dust collecting electrode length adjusting device and a homogenizing rod; the water distribution amount is adjusted by an adjusting valve, the thickness of the collecting electrode surface water film is controlled by a PLC; water flows into the upper part of a fabric collecting electrode through a water distribution hole to form an initial water film and then downwards spreads to the bottom in a corrugated shape; a wall-cooling wall surface formed by the water film contacts with a flue gas counterflow to generate friction lift force to be mutually coupled with flue gas condensed water and capillary characteristics of fiber fabrics, thereby promoting the rapid formation of the water film with uniform thickness; in the process of precipitating water condensation nuclei in the flue gas, micro fine particulate matters are condensed and the particle size is increased; and a grey cake layer formed by the micro fine particulate matters on the surface of the fabrics is fractured and shed in a flaky shape. The device has the outstanding effects of dust removal, demisting, energy saving and consumption reduction.

Switching device tank, arc extinguish chamber which uses switching device tank and high voltage switching device
InactiveCN104362036AAvoid the problem of being broken downAvoid impact erosionHigh-tension/heavy-dress switchesAir-break switchesDecomposerIonization
The invention discloses a switching device tank, an arc extinguish chamber which uses the switching device tank and a high voltage switching device. The arc extinguish chamber which uses the switching device tank is characterized in that an insulation sleeve and an insulation pad in the arc extinguish chamber are matched in touch mode or integrally arranged so as to form a hood body, the hood body covers the periphery of an electricity connection main body so as to separate a tank body together with an end cover from the electricity connection main body, and the internal face of the hood body is a baffling face used to block insulating gas ejected out from a blowout side of the hood body and baffle and deflect the insulating gas ejected out. When the switching device tank, the arc extinguish chamber which uses the switching device tank and the high voltage switching device are used, the insulating gas ejected out from a nozzle of a slave electricity connection end extinguishes high voltage arcs in a fracture mouth, and then is ejected out from a blowout side of the electricity connection main body, and simultaneously the insulating gas is not only still high in flow velocity and temperature, but also mingled with a certain amount of metal dust and ionization decomposer, and then the high temperature and high velocity mixed gas can crash onto the baffling face of the hood body, and therefore the mixed gas ejected out from the blowout side of the electricity connection main body is prevented from impacting and eroding the internal face of the tank body.

Bipolar transistor with floating ring structure
InactiveCN103681816AIncrease the areaReduce aggregationSemiconductor devicesOhmic contactEngineering
The invention relates to a bipolar transistor with a floating ring structure. The bipolar transistor comprises a substrate, a buffer zone, a collector region, a base region and an emission area, wherein ohmic contact areas are respectively arranged on the boundaries of the collector region and the base region; an emitting electrode is positioned on the emission area; a collecting electrode is positioned on the ohmic contact area of the collector region; a base electrode is positioned on the ohmic contact area of the base region; a plurality of floating rings are arranged at the periphery of the ohmic contact area of the collector region, positioned on the surface of the collector region and close to the ohmic contact area. Due to the adoption of the scheme, the technical problem that over high electric field strength at the edge of the ohmic contact area of the collecting electrode caused by an LBJT suppresses the improvement of blocking voltage in the prior art is avoided. Therefore, the bipolar transistor can bear higher blocking voltage.
