Abstract
The invention relates to a high-pressure alcoholysis device for producing fatty alcohol. The high-pressure alcoholysis device is designed mainly for solving the problem that much methanol contained in a product produced by a conventional 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; a methanol feeding pipeline and a palm kernel oil feeding pipeline are connected with a tube pass inlet of the material-material heat exchanger; a pipeline arranged at a tube pass outlet of the material-material heat exchanger is connected with an inlet of a heater; a pipeline arranged at an outlet of the heater is connected with an inlet of a reactor; a pipeline arranged at an outlet of the reactor is 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; 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 materials in the reactor and lowering the excessive amount of methanol.
Description
Technical field:
The present invention 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 palm-kernel oil to be sent in heat exchanger by the mass ratio of 1.1: 1, after heat exchange, deliver to heater, be heated to after uniform temperature, deliver to reaction in reactor, because the mass ratio of methyl alcohol and palm-kernel oil is 1.1: 1, the excessive 6-7 of methyl alcohol doubly, in product, also has a large amount of methyl alcohol, to arrive in next procedure and carry out separating methanol processing, increase next procedure energy consumption and burden, increase power consumption and the thermal energy consumption in production process.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of high-pressure alcoholysis device that can reduce methanol content in product.
Above-mentioned purpose is achieved in that it comprises material material heat exchanger, methanol feeding pipeline is connected with the tube side entrance of material material heat exchanger with palm-kernel oil feed pipe, 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 product discharge pipeline; It is characterized in that: we establish several cylindrical efficient mass transfer internals in reactor, and the top and bottom of these cylindrical efficient mass transfer internals are all fixed in reactor, on the surface of each cylindrical efficient mass transfer internals, have spiral groove.
The diameter of described cylindrical efficient mass transfer internals is 50mm, and gash depth is 10mm, and groove width is 10mm.
Advantage of the present invention is: owing to establishing several cylindrical efficient mass transfer internals in reactor, on the surface of each cylindrical efficient mass transfer internals, have spiral groove, material is 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 in reactor, occur strong radially mixing, reduce the time of staying of axial backmixing and material, material is evenly distributed, reduce methyl alcohol excessive amount, according to test, the excessive amount of methyl alcohol can reduce by 50%.
