Circular inverted cone type bubbling stirred tank reactor

Abstract

The invention relates to the technical field of bubbling stirred tank reactors. A circular inverted cone bubbling stirred tank reactor provided by the invention comprises a reaction kettle, a circular inverted cone bubbler, an inlet valve, an air inlet pipe, a discharge valve, a discharging pipe, bubbling holes, a connecting device, etc. The circular inverted cone bubbler is installed at a central part at the lower part of the reaction kettle and is connected with the air inlet pipe; the air inlet pipe is provided with the inlet valve; the bottom of the reaction kettle is connected with the discharging pipe, and the discharging pipe is provided with the discharge valve; the circular inverted cone bubbler is provided with N bubbling holes with varying directions; the external surface of the circular inverted cone bubbler is in a streamline shape, flowing resistance of a fluid is small, the moving trajectory of agitated bubbles is long, continuous stirring effects last for a long time, and high stirring efficiency is obtained; the bubbling holes are located at the lower part of a circular inverted cone, and bubbles move along an inclined downward direction at first and act on the bottom of the reaction kettle, leaving no stirring dead angle.

Description

technical field [0001] The invention relates to the technical field of bubbling stirred reactors. Background technique [0002] In chemical production, in order to fully mix and react the liquid-solid phase materials, the reaction kettle can be stirred by bubbling. The bubbling and stirring device of the prior art Chinese patent CN201887067U discloses a bubbling and stirring type cashmere tank rehydration device. The air hole realizes the stirring of the material in the reaction tank. This kind of stirring device has disadvantages. One is the vertically upward air outlet, the initial velocity direction is vertically upward, and the floating speed of the bubble is also vertically upward. The upward speed direction of the two-speed synthesis is quickly separated from the reaction interface, and the stirring efficiency is low, so the power consumption is large; second, it is easy to form a stirring dead angle at the bottom of the reactor; third, multiple bubbling stirring part...

The bubbling and stirring device of the prior art Chinese patent CN201887067U discloses a bubbling and stirring type cashmere tank rehydration device. The air hole realizes the stirring of the material in the reaction tank. This kind of stirring device has disadvantages. One is the vertically upward air outlet, the initial velocity direction is vertically upward, and the floating speed of the bubble is also vertically upward. The upward speed direction of the two-speed synthesis is quickly separated from the reaction interface, and the stirring efficiency is low, so the power consumption is large; second, it is easy to form a stirring dead angle at the bottom of the reactor; third, multiple bubbling stirring parts are placed at the bottom, and the structure is complex and easy to block , not conducive to cleaning

The Chinese patent with the application number 200910252129.0 has a simple structure and is easy to clean and maintain. However, there are also dead spots in the bottom of the reactor and the direction of the initial velocity is vertically upward. The floating speed of the bubbles is also vertically upward. The upward speed direction quickly breaks away from the reaction interface, the defects of large power consumption and low stirring efficiency
