Abstract

The invention relates to a tubular continuous reactor, which comprises reactor, heat exchanger and material pot used to contain materials. Wherein, it is characterized in that: it also comprises pre-mixer, circulate pump and flux controller; said mixer is tubular and mounted inside the heat exchanger, while its input via pre-mixer is connected to the output of circulate pump and the outlet of material pot with flux controller; the outlet of tubular reactor is connected to the buffer pot whose top has product outlet and bottom has input connected to another outlet of material pot with flux controller to connect the circulate pump; before reaction, the system is filled with final products, then start the circulate pump and material valve, via the power of circulate pump, the reaction materials are mixed by pre-mixer, to enter into tubular reactor to process esterification; and part of product will enter into thermal-insulated pot via the outlet of buffer pot to be stored, and another part enters into circulate pump to be stored in reactor.

Description

Technical field

[0001] The invention provides a tubular continuous reaction device, which belongs to the technical field of esterification reaction. Background technique

[0002] The traditional esterification reaction device mostly includes a liquid raw material metering device, a reactor with a dynamic agitator, a heat exchange device, a liquefied gas raw material vaporization tank, and a metering device. The gas raw material is subjected to bubbling absorption esterification reaction in the reactor. The disadvantage is that the latent heat of vaporization of the liquefied gas raw material is very large, and it needs to be heated and vaporized before entering the reactor. During the esterification reaction, a large amount of heat needs to be released when the reaction raw material is converted from a gaseous state to a liquid state. This heat needs to be cooled by a heat exchange device. High energy consumption and low efficiency. Moreover, the raw materials in the react...
