Metal small channel reactor

Abstract

The invention discloses a novel metal small channel reactor, relating to the technical field of material mixing and reaction equipment. The novel metal small channel reactor comprises a feeding hole, modules, a discharging hole, a heat exchanger inlet pipe and a heat exchanger outlet pipe, wherein the modules are alternatively stacked between the inlet pipe and the outlet pipe, which are arranged in parallel relatively; and the modules are connected through module connection pipes. Each module of the small channel reactor is composed of a pipe pass and a shell pass; and materials pass through a metering pump and are pre-heated, mixed and reacted in a pipe pass region; and a refrigerant medium in a shell pass region is used for controlling the temperature in the small channel reactor through an external heat exchanger. The mini-type reactor modules have excellent mass transferring and heat transferring effects and can bear very high operation pressure, and the highest pressure can reach 10Mpa; the production efficiency, the reaction speed, the safety and the like are improved to the great extent; and the novel metal small channel reactor has the properties of high strength, small density, good mechanical properties and good toughness and corrosion resistance, engineering enlargement is convenient to realize, and a production process from a laboratory scale to industrial production is finished in one step.

Description

technical field [0001] The invention relates to the technical field of material mixing and reaction equipment, in particular to a small metal channel reactor. Background technique [0002] Microchannel reactor equipment can be subdivided into micromixers, microheat exchangers and microreactors according to their main usage or function. Due to its internal microstructure, the microchannel reactor equipment has a very large specific surface area, which can reach hundreds or even thousands of times of the specific surface area of ​​the stirred tank. Microchannel reactors have excellent heat and mass transfer capabilities, and can achieve instant uniform mixing of materials and efficient heat transfer, so many reactions that cannot be realized in conventional reactors can be realized in microchannel reactors. Existing microchannel reactors are not effective in controlling the flow of feed materials, the pressure is small, the production efficiency is low, and the reaction speed...
