The present invention utilizes a high-speed serial data transceiver to generate two high-speed electric pulse signals. After passing through a gain network, the signals are used for driving an electro-optic phase modulator (PM) so as to realize phase modulation of photon signals. The present invention may directly use a high-speed digital signal to realize a four-phase modulation function needed by the BB84 quantum key distribution protocol without using a digital to analog converter or an analog switch. This can prevent modulation rate from being restricted by links including digital-to-analogue conversion, switching of the analogue and the like. A dual-electrode electro-optic phase modulator scheme can also effectively reduce requirements for amplitude of a modulation driving signal, thus facilitating realization of high-speed phase modulation, which meets requirements of quantum key distribution.

A catalytic reaction-rectification integrated process and a catalytic reaction-rectification integrated column, and the specialized device of such process is provided. The reactants are preheated and mixed with catalysts, and then fed into a jet agitation reaction section located in the middle of the catalytic reaction-rectification integrated column from a feeding inlet. The jet agitation reaction section is a kettle-like reactor located in the middle of the catalytic reaction-rectification integrated column. After pressurized by a centrifugal pump, the reactant materials are admitted into a subsonic or transonic agitator located within the reaction section. The reactant materials are ejected into the jet agitation reaction section at high speed, to efficiently mix the solid and liquid phases in the reaction section and to reinforce heat and mass transfer efficiency during the reaction. The liquid reaction mixture is separated and purified directly in the catalytic reaction-rectification integrated column.

This invention relates to the core component of a floating valve tray-floating valve. The objective is to provide a parent-and-subsidiary flow-guided floating valve of low pressure drop, high throughput and highly flexible operation that can maintain high efficiency within a wide range of gaseous load changes. The technical proposal is: a parent-and-subsidiary flow-guided floating valve, wherein the body of the parent valve is a symmetrical plane figure with the central axis line as the symmetrical line, the central axis line points to the overflow cofferdam along the direction in which the liquid flows and there are at least 2 legs below the body of the parent valve. The front leg is longer than the rear leg so that when the parent valve is fully open, a 2-10 degree angle opens between the body of the parent valve and the valve orifice toward the overflow cofferdam. On the body of the parent valve is a parent valve hole, on which is the subsidiary valve, which is a movable valve smaller than the parent valve in terms of area with its circumference parallel to that of the parent valve. There are at least 2 legs under the body of the subsidiary valve and the front leg is equal to or longer than the rear leg so that when the subsidiary valve is fully open, a 0-10 degree angle opens between the body of the subsidiary valve and the body of the parent valve toward the overflow cofferdam.
