Tube type precipitation reactor

Abstract

The invention discloses a pipeline-typed precipitation reactor which belongs to the technical field of pipeline reaction devices. The wall of the pipeline-typed precipitation reactor is provided with a jacket, an upper medium inlet and a lower medium outlet, and heating and cooling operations can be realized through heating or cooling the medium according to reaction needs. The interior of the pipeline-typed precipitation reactor is provided with a high-speed agitating impeller which is fixed respectively by an upper end enclosure and a bearing in a lower bracket, and connected with an electric motor at the upper part of the reactor. Two material inlets are arranged along a tangential direction on a top lateral surface of the reactor, and are respectively connected with the pipelines of two constant-voltage material feeders or pumps. Two types of materials are respectively fed into the pipeline-typed precipitation reactor through the two material inlets and carry out instantaneous hybrid reaction under high-speed rotation of the agitating impellers. The bottom of the reactor is open, and precipitation products are discharged through the bottom. The pipeline-typed precipitation reactor is convenient for realizing the size and distribution control of the precipitation reaction particles, reduces manual factors, and obtains narrow distribution and precipitation particle products with good batch stability.

Description

technical field [0001] The invention relates to a pipe-type precipitation reactor, in particular to a reactor in which liquid and liquid are instantly mixed and reacted in the pipe to form precipitation. It belongs to the technical field of pipeline reaction devices. Background technique [0002] The industrial method of obtaining powder materials through precipitation reaction is generally carried out in a reactor. Regardless of the feeding methods such as forward feeding, reverse feeding or combined feeding, the formation of precipitated crystal nuclei and the growth of crystals are often carried out at the same time. Relatively speaking, the distribution of particles is relatively wide, and the feeding process is mostly controlled manually, and the flow rate is controlled. Human factors are more likely to lead to a broad particle distribution of the product or poor stability of the product batch. To obtain powder particles with a narrow distribution, it is hoped that th...
