(3) utility model content
The utility model, in order to make up the deficiencies in the prior art, provides the Novel mixer of a kind of structure application in hydriding reactor simple, easy to use, and this agitator adopts upper and lower two-layer self-priming paddle B.In operation process, the hydrogen on liquid level in still is drawn at the bottom of still by self-priming paddle B, by again disperseing hydrogen at the bottom of still, increases the contact area of hydrogen and material; The catalyst that proportion is larger suspends in the solution.When adopting this combination, the gas circulation that upper-layer paddle effectively disperses by lower floor's oar enters lower area, the bottom bad and bubble of coalescence of dispersion after entering upper area again disperse by the oar of high shear and circulate again, therefore the gas phase time of staying can effectively be extended, improve gas holdup, be conducive to the increase of gas-liquid mass transfer specific area.
The utility model is achieved by the following technical solution:
A kind of hydriding reactor self-absorbing type stirrer, comprise self-priming paddle A, self-priming paddle B, self-priming paddle A, self-priming paddle B is positioned in the hollow shaft of hydriding reactor from top to bottom successively, its special character is: this self-priming paddle comprises columniform shaft, this shaft is communicated with three stationary pipes, between two stationary pipes, angle is 120 °, shaft is fixed by stationary pipes and is communicated with tube connector, tube connector is vertical with shaft or close vertical, the installation cross section, outside of this tube connector is V-type blade, the baffle plate that the bubble of overflowing from oar end is broken up by two paddle arranged outside.
The Novel mixer of the application in hydriding reactor of the present utility model, perforate on shaft, this hole is corresponding with stationary pipes.
The beneficial effects of the utility model are: the rotating shaft of described New type agitation oar has 2 layers of self-priming paddle.The utility model paddle, can increase substantially the contact area of gas holdup and liquid phase, thus improve reaction rate.When self-priming paddle rotates with certain speed, the impeller of high-speed cruising can make large quantity of fluid circulate inside and outside impeller, according to venturi ejector principle, gas on liquid level is discharged from impeller by after the liquid entrainment of high-speed motion by hollow shaft, negative pressure is formed in self-priming paddle, in hydriding reactor, the gas of ullage is sucked by hollow shaft upper end aperture, downward along hollow shaft, and bloated by stirring axis hole, bubble is overflowed from oar end, move to still wall, very little bubble is broken into by baffle plate, gas forms circulation in hydriding reactor, solid particle floats on a liquid, gas fully contacts with particle.Like this, gas is constantly sucked into liquid phase deep layer in hydriding reactor, and is stirred dispersion, go round and begin again, form uniform gas-liquid mixed, realize high efficient gas and liquid contact, strengthening mass-transfer progress, substantially reduces the gas liquid reaction time, improves the utilization rate of hydrogenation reaction speed and hydrogen.
