Abstract
The utility model discloses a high-pressure alcoholysis device and relates to the high-pressure alcoholysis device for producing fatty alcohol, which is designed for mainly solving the problem that much methanol contained in a product produced by the existing high-pressure alcoholysis device needs to enter a next process to be subjected to methanol removing treatment. The high-pressure alcoholysis device comprises a material-material heat exchanger, wherein a methanol charging pipeline and a palm kernel oil charging pipeline are connected with a tube pass inlet of the material-material heat exchanger; a pipeline is arranged at a tube pass outlet of the material-material heat exchanger and connected with an inlet of a heater; a pipeline is arranged at the outlet of the heater and connected with an inlet of a reactor; a pipeline is arranged at an outlet of the reactor and connected with a shell pass inlet of the material-material heat exchanger; a shell pass outlet of the heat exchanger is connected with a product discharging pipeline; a plurality of cylindrical efficient mass transfer inner pieces are arranged in the reactor; the upper ends and the lower ends of the cylindrical efficient mass transfer inner pieces are fixed in the reactor; and a spiral groove is arranged on the surface of each cylindrical efficient mass transfer inner piece. The high-pressure alcoholysis device has the advantages of being capable of strengthening the mixing of the materials in the reactor and lowering the excessive amount of the methanol.
Description
Technical field:
The utility model relates to a kind of high pressure alcoholysis device that fatty alcohol is used of producing.
Background technology:
Existing high pressure alcoholysis device is with high-pressure pump methyl alcohol and the palm-kernel oil mass ratio by 1.1: 1 to be sent in the heat exchanger, deliver to heater after the heat exchange, after being heated to uniform temperature, deliver to the reactor internal reaction, because the mass ratio of methyl alcohol and palm-kernel oil is 1.1: 1, the excessive 6-7 of methyl alcohol doubly, also has a large amount of methyl alcohol in the product, to arrive and carry out the separating methanol processing in the next procedure, increase next procedure energy consumption and burden, namely increase power consumption and the thermal energy consumption in the production process.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of high pressure alcoholysis device that can reduce methanol content in the product.
Above-mentioned purpose is achieved in that it comprises material material heat exchanger, the methanol feeding pipeline is connected with the tube side entrance of palm-kernel oil feed pipe with material material heat exchanger, the tube side outlet of material material heat exchanger has pipeline to be connected with the entrance of heater, the outlet of heater has pipeline to be connected with the entrance of reactor, the outlet of reactor has pipeline to be connected with the shell side entrance of material material heat exchanger, and the shell side outlet of heat exchanger is connected with the product discharge pipe; It is characterized in that: we establish several cylindrical efficient mass transfer internals in reactor, the top and bottom of these cylindrical efficient mass transfer internals all are fixed in the reactor, have spiral groove on the surface of each cylindrical efficient mass transfer internals.
The diameter of described cylindrical efficient mass transfer internals is 50mm, and gash depth is 10mm, and groove width is 10mm.
The utility model has the advantages that: owing in reactor, establish several cylindrical efficient mass transfer internals, have spiral groove on the surface of each cylindrical efficient mass transfer internals, material is shape motion in the shape of a spiral in reactor, so can strengthen the mixing of material in reactor, improve the contact condition of material, increase contact probability, make reaction mass strong radially mixing in reactor, occur, reduce the time of staying of axial backmixing and material, material is evenly distributed, reduce the methyl alcohol excessive amount, according to test, the excessive amount of methyl alcohol can reduce by 50%.
