Problems solved by technology

The particle size distribution is better than that of the reactor, but the stability is poor, especially the proportion of small particles is large, the product dispersion is significantly reduced, the repeatability of the particle size distribution is low, and it is difficult to control accurately
The reason is that the flow shape of the material in the chute is unstable, the flow rate near the edge is low, the reaction is slow, and the particles are large. The flow rate in the center is high, the reaction is fast, and the particles are small. Therefore, the proportion of extremely small particles and extremely large particles in the product is large, and the product performance is poor.

experiment example

[0040] By adopting different nozzle diameters of the outlet section of nitric water feed pipe 1 and the diameter of the outlet section of barium brine feed pipe 2, it is proved that the nozzle diameter of the outlet section of nitric water feed pipe 1 and the outlet section of barium brine feed pipe 2 are The diameter of the orifice can lead to disordered distribution of barium sulfate particles.

[0041] Experimental process: barium sulfate is obtained by using the barium sulfate reactor used in the present invention, and the barium sulfate particle size distribution diagram is obtained by a BT-9300S laser particle size distribution analyzer. In the barium sulfate particle size distribution diagram, the horizontal axis of the coordinate axis represents the particle size of barium sulfate (in microns), the vertical axis of the coordinate axis of the S-shaped curve corresponds to the value of the vertical axis of the left coordinate axis, and the S-shaped curve represents the pa...

Abstract

The invention provides a precipitated barium sulfate continuous chemical combination reactor, which comprises a nitrate water feeding pipe, a barium brine feeding pipe, a discharging pipe, a tank bodyand a stirring mechanism; a first through hole is formed in the top of the tank body, the nitrate water feeding pipe is inserted into the first through hole and can move up and down relative to the tank body, and a second through hole is formed in the lower portion of the tank body; a barium brine feeding pipe is inserted into the second through hole, a pipe opening of the barium brine feeding pipe is located under a pipe opening of the nitrate water feeding pipe and is opposite to the pipe opening of the nitrate water feeding pipe, a third through hole is formed in the bottom of the tank body, the discharging pipe is inserted into the third through hole, and the stirring mechanism is fixed relative to the tank body and stirs the liquid in the tank body. The particle size and the particlesize distribution of barium sulfate are controlled by changing the distance between the nitrate water feeding pipe and the barium brine feeding pipe.

Description

technical field [0001] The invention relates to the field of continuous compounding reactors for precipitated barium sulfate, in particular to a continuous compounding reactor for precipitated barium sulfate capable of controlling the barium sulfate particle size and particle size distribution. Background technique [0002] The compounding process of barium sulfate precipitation by Glauber's salt method is extremely important, and it is a key step in controlling particle size and particle size distribution. The application fields of barium sulfate with different particle sizes and distribution forms are also very different. Therefore, the ability to precisely control the particle size and distribution of barium sulfate is a dream pursued by the barium sulfate industry by Glauber's salt method for decades. Previously, the reactors used in the industry mainly include batch reactors and chute reactors. [0003] The reaction kettle produces barium sulfate intermittently, and n...
