Abstract

The invention relates to a micro-channel reactor for producing nano sulfate and belongs to the technical field of chemical reaction equipment. The micro-channel reactor provided by the invention has the benefits that through the arrangement of a three-layer structure and a multistage reaction unit, feeding is more accurate, and reaction materials are more uniformly mixed, and the laminar flow phenomenon of feed liquid occurring in the collision reaction process is overcome, so that the reaction is closer to a flow state, the contact in the reaction process is more full, and the reaction is more thorough; the re-agglomeration of nano sulfate generated by collision reaction can be effectively avoided, so that a product is kept in a nanometer form and is uniform in particle size, and further, a high-quality nano sulfate product is prepared.

Description

technical field [0001] The invention relates to a microchannel reactor, more particularly, the invention relates to a microchannel reactor for producing nano-sulfate, belonging to the technical field of chemical reaction equipment. Background technique [0002] Currently through BaCl 2 with NaSO 4 Preparation of Nano-BaSO by Reaction 4 The reaction method of collision is mainly used, and the BaCl prepared according to the one-to-one feed ratio is about to be used. 2 with NaSO 4 The solution is accurately metered by the metering pump and injected from both ends of the reactor at the same time, and the two groups of solutions are collided and combined in the reactor at a certain speed and pressure to form BaSO 4 a way of reacting. Other nano sulfates such as the preparation of nano calcium sulfate whiskers can also be prepared by the above method. [0003] The method for producing nano barium sulfate in the existing reactor mainly has the following deficiencies: [0004...
