Abstract

The utility model relates to a synthesis reactor, and the utility model is particularly applicable to a catalytic hydrogenation producing process of castor oil and other thermosensitive oil and grease. The technic proposal of the utility model is that: the utility model includes a reactor body, a drive mechanism which is arranged on the reactor body, a plurality of material inlets and outlets which are arranged at the outside of the reactor body, a mixing shaft and mixing blades which are arranged in the reactor body, the utility model is characterized in that: the mixing blades which are fixed on the mixing shaft are arranged into a plurality of groups from up to down, wherein, the group which is arranged at the lowest is a turbine type structure which consists of a plurality of blades, and others are dual-blade relay type cycling mixing blades. The ratio of the height of the reactor body and the diameter is about 3:1, the relay type cycling mixing blades use a plurality of groups from up to down, the blades of each group of the mixing blades are radial and in a reverse deflection angle. The improvement with a plurality of aspects increases the effective volume of the materials in the reactor; the relay type cycling mixing blades can facilitate the materials which are arranged higher in the reactor to flow and mix between the upper and lower layers thoroughly; the bottom part of a mixing machine uses the turbine type mixing blades, then the gas can pass through the bottom part of the reactor body, the gas can be shattered into the bubbles by the mixing of the turbine blades at the lower part, the gas is dispersed in the fluid body, the liquid and gas contact surface is increased, and the solubility of the gas in the liquid is also increased.

Description

A kind of synthesis reaction vessel

One, technical field: the utility model relates to a kind of synthesis reaction vessel, and the catalytic hydrogenation production process that is specially adapted to grease is used.

Two, background technology: existing reactor comprises the compositions such as several feed inlet and outlets, the shaft in the kettle and paddle that driving mechanism, the kettle on kettle, the kettle is outer.The height of general reactor kettle, diameter are than being 1.5-2: 1, and withstand voltage degree is low; And the blade of paddle adopts symmetry, single ramp structure form, like this when paddle rotates, fluid has formed in reactor up or down and has flowed to, be unfavorable for the abundant mixing of the various compositions in the fluid, thereby prolonged mixing time and reaction time, reduced the operating efficiency of reactor.

Three, summary of the invention: the purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of high pressure resistant and can produce multithread to the synthesis reaction vessel that stirs.

Its technical scheme is outer several feed inlet and outlets, interior shaft and the paddle of kettle of driving mechanism, kettle that comprises on kettle, the kettle, it is characterized in that: the paddle upper and lower settings that is fixed on the shaft is several groups, wherein the most beneath one group is the turbotype structure that multiple-blade is formed, and other is the relay-type circulation paddle of twayblade.Kettle height and diameter were than about 3: 1, and relay-type circulation paddle adopts many up and down groups, and the blade radial of every group of paddle is reverse deflection angle.The inner wall of kettle device has heat exchanger and appendix, with it the kettle of Pei Heing outward respectively device inlet and outlet connectors is arranged, and offer manhole in a side of kettle.More than the improvement of several aspects, brought special-effect:

1, the kettle draw ratio is about 3: 1.This ratio can make equal wall thickness equipment can bear higher pressure, and the shared dischargeable capacity of material increases in the still, reduces invalid volume.

2, according to the size of reactor volume, two groups or more relay-type circulation paddle of upper and lower settings making the mixing of fully flowing between the material levels in the higher still.

3, the turbine type paddle is adopted in the agitator bottom, and gas feeds at autoclave body bottom, is subjected to the stirring of bottom turbine leaf, smashes bubble, and gas dispersion at fluid, is increased liquid, gas contact-making surface, increases the solubility of gas in liquid.

Four, description of drawings: accompanying drawing is the structure chart that has provided a kind of oil hydrogenation reactor.

Five, specific embodiment:

With reference to accompanying drawing, drive motors 1 is contained in the top of kettle 11, and the kettle outside is provided with charge door 2, air inlet 8, heat exchanger interface 7 and 9, discharging opening 13 and a manhole 3 that makes things convenient for personnel to pass in and out; Comprise the escape pipe 12 of the heat exchanger coils 5, air inlet pipe and the air inlet pipe that are coiled in inwall in the kettle, link to each other with motor on the shaft 10 that to autoclave body bottom, center fixed has two groups of relay-type circulation paddles 4 and one group of turbine type paddle 6 down.Two groups of relay-type circulation paddles 4 are made up of two groups of blades of horizontal symmetrical respectively, every group of blade radial is reverse deflection angle, and when rotating like this, liquid forms two kinds of reverse flow up and down vertically from inside to outside, composition composition in the kettle is mixed, improve reaction speed.The turbine type paddle is adopted in the agitator bottom simultaneously, and gas feeds at autoclave body bottom, is subjected to the stirring of bottom turbine leaf, smashes bubble, and gas dispersion at fluid, is increased liquid, gas contact-making surface, increases the solubility of gas in liquid.

Claims

1, a kind of synthesis reaction vessel, comprise outer several feed inlet and outlets, interior shaft and the paddle of kettle of driving mechanism, kettle on kettle, the kettle, it is characterized in that: the paddle upper and lower settings that is fixed on the shaft is several groups, wherein the most beneath one group is the turbotype structure that multiple-blade is formed, other is the relay-type circulation paddle of twayblade, and the blade radial of every group of paddle is reverse deflection angle structure.

2, according to claim 1 described synthesis reaction vessel, it is characterized in that: kettle height and diameter were than about 3: 1, and relay-type circulation paddle adopts many up and down groups.
