Abstract
The utility model provides a turbine-impeller self-sucking stirrer, comprising a joint and a hollow rotary shaft which is connected with the joint. The hollow rotary shaft is communicated with a suction hole on the joint. A recurrent pipe is vertically fixed on the lower end of the hollow rotary shaft and is communicated with the hollow rotary shaft. The outer wall of the recurrent pipe is fixed with a left vane and a right vane which are in parallel with the hollow rotary shaft. The utility model has the advantages of simple structure and light weight, can reduce the strength requirement and the stirring power requirement of the hollow rotary shaft, obviously improves a gas and liquid contacting effect, has an even degree of scatter, reaches a better mixing level, and therefore, improves reaction efficiency. The utility model is suitable for the reaction of gas and liquid and for the heterogeneous reaction of gas, solid and liquid.
Description
The utility model relates to a kind of agitator, particularly a kind of turbine oar self-absorbing type stirrer.
The agitator that adopts in the heterogeneous phase chemistry preparation feedback is of all kinds, as non-self-absorbing type stirrer, comprises frame, turbine type, flat leaf oar formula etc., and when this class agitator was used for gas, liquid or gas, solid, liquid reaction, utilization rate was not high, and mass transfer effect is poor; On chemical industry, prepare dimethyl ester as the liquid phase oxidative carbonylation of methanol method, be 90～150 ℃ of reaction temperatures, under reaction pressure 1.0～5.0MPA condition, the gas that carries out, liquid, Gu three-phase heterogeneous reaction, and for the three-phase system of different suspension concentrations and ventilation levels, the performance of suspension reactor is bordering on gas-liquid systems to a great extent, usually adopt self-absorbing type stirrer, as two disc turbine oars of six leaves and prismatic agitator etc., but for the liquid phase oxidative carbonylation of methanol method prepares the dimethyl ester reaction system, because extremely strong corrosivity is arranged, solid content is higher, and catalyst easily deposits factors such as obstruction, is not suitable for adopting the self-absorbing type stirrer of parts complexity as mentioned above.
It is a kind of simple in structure that the purpose of this utility model is to provide, and mass transfer effect is good, is applicable to the turbine oar self-absorbing type stirrer of gas, liquid and gas, liquid, solid heterogeneous reaction.
The utility model turbine oar self-absorbing type stirrer is to realize like this, it comprises joint, the hollow rotating shaft that is connected with joint, hollow rotating shaft communicates with suction hole on the joint, the recurrent canal that is vertically fixed on the hollow rotating shaft lower end and is communicated with it is fixed with the left and right blade parallel with hollow rotating shaft on recurrent canal outer wall.Wherein, recurrent canal is generally 1～2, totally 2～4 pieces of blades.
The operation principle of the utility model turbine oar self-absorbing type stirrer is, rotate with certain speed in liquid center by hollow rotating shaft, the low-pressure area of blade back is communicated with the liquid superjacent air space, thereby utilize the portion of energy of hollow rotating shaft to suck gas from liquid level, disperse bubble by blade again, reach, make gas in liquid, keep (recirculation) sufficiently long time being scattered in the whole liquid after the gas pulverizing, produce bigger phase contact area, help reaction and carry out.Under the certain situation of agitator structure, size, material, its air inflow depends on mixing speed, raising along with mixing speed, the degree of scatter of gas and solid improves thereupon, and blade form behind the height turbulence, increase inspiratory capacity, after rotating speed surpassed critical speed, reaction effect was better.
The advantage of the utility model turbine oar self-absorbing type stirrer is simple in structure, in light weight, can reduce requirement of strength and power of agitator to hollow rotating shaft, significantly improve gas-liquid contact effect, degree of scatter is even, reach good mixed-level, and the relation between energy coordination optimization throughput and speed of agitator, thereby reaction efficiency improved.Be applicable to the gentle solid-liquid heterogeneous reaction of gas liquid reaction for preparing dimethyl carbonate as the liquid phase oxidative carbonylation of methanol method.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
