Agitated reactor without dead angle

Abstract

The invention discloses an agitated reactor without a dead angle, and belongs to the technical field of reaction kettles. The agitated reactor without the dead angle comprises a reactor body, a bubble agitator, an air inlet valve, an air inlet pipe, an air compressor, a discharging pipe, a discharging valve and bubble overflowing holes. The agitated reactor without the dead angle is characterized in that the reactor body is a cone-base reactor, the bubble agitator is of an inverted-cone shape, the bubble overflowing holes are formed in the side face of a conical body of the bubble agitator, the bubble agitator is arranged at the bottom of the reactor body, the conical top of the bubble agitator is connected with the air inlet pipe, the air inlet valve is installed on the air inlet pipe, the air inlet valve is connected with the air compressor, the conical side face of the bubble agitator is an inwards-concave cambered surface, the equal-hole-diameter bubble overflowing holes are formed in the conical side face of the bubble agitator, the diameter of each bubble overflowing hole is 2-5mm, and the bubble overflowing holes are evenly distributed along the inwards-concave side face of the conical body. The agitated reactor without the dead angle has the advantages of being simple in structure, convenient to install and maintain and low in power consumption.

Description

technical field [0001] A stirred reactor without dead ends relates to the technical field of reactors. Background technique [0002] In chemical production, in order to fully mix and react the liquid-solid phase, the materials in the reactor are fully stirred and mixed in the form of spiral stirring, so that they can fully react. However, mechanical stirring, through the gear shifting of the motor through the gearbox, can reduce the speed of the stirring and then stir the materials in the reactor. However, the motor consumes a lot of power, the speed change device needs maintenance, and the production cost is high. Production also has the use of bubbling stirring. The bubbling stirring device of the prior art Chinese patent CN201887067U discloses a bubbling stirring type cashmere tank replenishment device, but its structure is complicated, and the bubbling form of the air outlet on the square tube is adopted.

Problems solved by technology

However, mechanical stirring, through the gear shifting of the motor through the gearbox, can reduce the speed of the stirring and then stir the materials in the reactor, but the motor consumes a lot of power, the speed change device needs maintenance, and the production cost is high.

Production also has the use of bubbling stirring. The bubbling stirring device of the prior art Chinese patent CN201887067U discloses a bubbling stirring type cashmere tank replenishment device, but its structure is complicated, and the bubbling form of the air outlet on the square tube is adopted. The gas flow can stir the materials in the reactor through the air outlet holes in the vertical and horizontal directions of the square tube. This kind of stirring device has shortcomings. The speed is also vertically upward. After the bubbles leave the air outlet, they quickly leave the reaction interface in the direction of the upward speed synthesized by the two speeds. The power consumption is large and the stirring efficiency is low; the second is easy to form a dead corner at the bottom of the reaction kettle; the third is multiple bubbling stirring parts. Placed at the bottom, and the structure is complex, easy to block, not conducive to cleaning

Chinese patent CN102078778A has a simple structure and is easy to clean and maintain, but there are also dead spots in the bottom of the reactor and the direction of the initial velocity is vertically upward, and the floating velocity of the bubbles is also vertically upward. Quickly break away from the reaction interface, the defects of low bubble stirring efficiency and large power consumption
