Embodiment Construction

[0014] figure 1 , figure 2 , image 3 It is a structural schematic diagram of an embodiment of the present invention,

[0015] Such as figure 1 and 2 As shown, a vertical cylindrical paddle shaft 1, the end of the paddle shaft 1 is connected with the upper disc 3 through the fixed ring 2, the center of the lower disc 5 is provided with an air inlet, and a short pipe is welded around the lower side of the air inlet as a Air intake guide tube 6, easy self-gathering gas intake pipe 7 ends are placed in the intake guide tube 6. Depend on image 3 It can be seen that the upper disk 3 and the lower disk 5 are connected by arc-shaped blades 4 to form a curved-blade disk turbine. The arc-shaped blades 4 are distributed in a turbine-like shape, with a total of 8 pieces and a cavity in the center. 1 to 4 layers of stirring paddles can be installed on the stirring shaft, and each layer of paddles contains 2 to 12 Rushton turbine blades 8 . figure 1 Two layers of Rushton turbine b...

Abstract

The invention relates to a stirring propeller for sucking and dispersing easy-to-self-polymerized gas, which comprises a vertical cylindrical propeller shaft and an easy-to-self-polymerized gas inlet pipe. The stirring propeller is characterized in that the end of the cylindrical propeller shaft is connected with the upper circular disc of a curved disc turbine through a fixing ring, the center of the lower circular disc of the curved disc turbine is provided with a gas inlet; the periphery of the gas inlet is connected with a gas inlet diversion cylinder, the end of the easy-to-self-polymerized gas inlet pipe is arranged in the gas inlet diversion cylinder, the peripheries of the upper circular disc and the lower circular disc are connected through 4-12 arc-shaped blades which are distributed in a turbine shape. The invention has the advantages that: during the stirring, the strong negative pressure can be generated at the center of the turbine to pump the gas in, thereby reducing the gas conveying pressure and reducing the self-polymerization; the gas pumped in can be sprayed out along the radial directions of the circular discs along the swirling channel, thereby preventing the gas from passing through the low shear zone around the hub, and achieving high stirring efficiency and good dispersing effect; and blades can be additionally arranged on the stirring shaft to enhance the gas dispersing effect.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and relates to an industrial reactor material stirring paddle for gas-liquid mixed reaction, in particular to a stirring paddle for sucking and dispersing self-polymerizing gas. Background technique [0002] Industrial reactors are widely involved in the gas-liquid reaction process. The gas phase material is passed into the bottom of the reaction vessel through the inlet pipe, and is stirred by the stirring paddle to achieve uniform mixing with the liquid phase material for reaction. At present, propellers, inclined-blade turbines or diskless impellers are mostly used in the industry for gas-liquid mixing and stirring blades, and the flow pattern generated by them is often that the fluid flows in a direction parallel to the shaft of the paddle. Axial flow is not conducive to controlling the uniformity of gas distribution and controlling the size of bubbles, and it is easy to produce ag...
