(3) summary of the invention
The shortcoming that existing hydrogenation reactor mass-transfer efficiency is low, sealing is poor in order to solve, metering is inaccurate, the utility model provide that a kind of mass-transfer efficiency height, sealing are strong, the ultrasonic hydrogenation reactor of accurate measurement.
The utility model adopts following technical scheme:
A kind of ultrasonic exciting hydrogenation reactor comprises reaction vessel and hydrogen air accumulator, and described reaction vessel is arranged in the pendulum cover, and described pendulum cover is connected with swing mechanism; Be connected with control valve and Pressure gauge between described reaction vessel and the described hydrogen air accumulator, the air inlet, working hole, the exhaust outlet that are communicated with described hydrogen air accumulator, reaction vessel and the external world are respectively arranged on the described control valve, and described Pressure gauge communicates with the inner chamber of described control valve; Described reaction vessel is provided with heater and attemperating unit; The bottom of described reaction vessel is provided with ultrasonic oscillator, and described ultrasonic oscillator is connected with the supersonic generator signal.The power of described swing mechanism connects and reduction box between the two from motor.Described control valve can be a single valve, also can be that a plurality of valves are formed by connecting.
Further, the exit of described reaction vessel has blind nut to compress hermetically-sealed construction.
Further, described heater is covered on the outer wall of described reaction vessel.
Reaction container bottom is provided with ultrasonic oscillator, and ultrasonic wave is more violent by the vibration of bottom excitation material, increases gas-liquid contact area and transmission speed, strengthens the mass transfer and the reaction of gas-liquid in the reactor, can select ultrasonic frequency and power according to material characteristic.Reactor content is imported and exported and is adopted blind nut to compress hermetically-sealed construction, makes the interior gas of reactor not have leakage, and reactor adopts stainless steel material, reactor is not corroded also can bears pressure.Control valve can be finished air inlet and degassing function well, contains Pressure gauge, accurately assaying reaction pressure and the consumption that measures hydrogen; Also have heater and attemperating unit, can control reaction temperature effectively.Adopt reaction vessel integral body to wave structure, make the reaction vessel that is arranged in the pendulum cover wave under the mechanical force of swing mechanism, the oscillating force of generation promotes the mass transfer and the reaction of gas-liquid in the reaction vessel, can select hunting frequency as required.
The beneficial effect of hydrogenation reactor described in the utility model is mainly reflected in: (1) has adopted ultrasonic exciting, has further aggravated the mass transfer of gas-liquid, has promoted hydrogenation reaction; (2) adopt blind nut to compress hermetically-sealed construction, help improving reaction pressure and fast reaction speed.(3) adopt the heating equipment, help improving reaction temperature and fast reaction speed.(4) adopt reaction vessel integral body to wave structure, strengthened the mass transfer of gas-liquid, help hydrogenation reaction; (5) the reaction compartment sealing is reliable, does not have movable sealing.
