Abstract
The utility model provides a series combination high-temperature conduction oil heating reaction still. Each reaction still mainly comprises a still body, a clamp sleeve cylinder, an electric heater, a discharging pipe and a liquid accessory inlet. The reaction stills are characterized in that clamp sleeves of two reaction stills are connected in series through a guide pipe at the bottom, a conduction oil bottom valve is arranged between each clamp sleeve and each guide pipe, and the clamp sleeve of each reaction still is provided with a compressed air inlet and a compressed air outlet. Each reaction still is used for reaction that diosgenin is combined to aitificial diosgenin diacetate in an open-loop mode, oil temperature of each clamp sleeve is even, product conversion rate is improved, reaction heating time and still cooling time are greatly shortened, and electric energy is saved.
Description
Technical field
The utility model belongs to chemical production equipment, is specifically related to a kind of high temperature heat conductive oil reacting by heating still of series combination.
Background technology
In by the process of diosgenin through acidylate and the synthetic false diosgenin diacetate of ring-opening reaction, this reaction needs to carry out under high temperature high pressure enclosed condition.The structure of reactor mainly comprises high temperature high voltage resistant stainless steel kettle cylinder, thermal oil jacket cylinder, electric heater, the discharge nozzle bottom the insertion of reactor top, reactor top feed intake manhole, Auxiliary Liquid Material import, valve tube interface, vacuum pressure gauge interface, thermometer boss, discharge nozzle interface etc., the principle of work of reactor is by the thermal oil in the electrically heated chuck, with heating material to 0.6MPa, react complete, by self pressure in the still material is extruded.
Existing ring-opening reaction still all is independent use in process of production, went out the tank needs 5 ~ 6 hours from being heated to material, the question response still naturally cools to 40 ~ 50 ℃ just can cast a batch materials, usually need 5 ~ 6 hours cooling time, not only heat-up time and cooling time long, and the heat energy of thermal oil has been wasted, the utilization ratio of reactor is low like this, production cycle is long, and energy dissipation is large.Because electric heater is heated base only, the thermal oil in the chuck is in a kind of relatively static, and heat-conducting oil speed is slow, thereby makes reactor temperature up and down irregular, affects the transformation efficiency of ring-opening reaction.
Summary of the invention
It is a kind of with short production cycle that the purpose of this utility model will provide exactly, save energy, and Heating temperature is even up and down for reactor, the high temperature heat conductive oil reacting by heating still of the series combination that the transformation efficiency of ring-opening reaction is high.
The high temperature heat conductive oil reacting by heating still of series combination of the present utility model, each reactor mainly comprises kettle cylinder, jacket cylinder, electric heater, discharge nozzle, the Auxiliary Liquid Material import, its improvements are: two reacting kettle jacketing cylindrical shells are passed through bottom conduit coupled in series, the thermal oil bottom valve is housed between jacket cylinder and the conduit, and compressed air inlet port and venting port are equipped with in each reacting kettle jacketing cylindrical shell top.Two reacting kettle jacketing cylinder body bottoms all are designed to pyramidal structure.
Through the reactor after improving, can stir thermal oil in the chuck by passing into pressurized air, temperature is even up and down thereby make thermal oil, stir several minutes after, close corresponding valve.When the reaction of one of them reactor complete, same method thermal oil is pressed into or another reacting kettle jacketing of suction in.Conical design is adopted in the jacket cylinder bottom, is conducive to thermal oil is all changed in another reacting kettle jacketing.Materials conversion rate of the present utility model has improved approximately 5%, and it is nearly 50% that reaction has been shortened heat-up time, and it is nearly 70% that kettle has shortened cooling time, electric energy saving nearly 35%, greatly improved working efficiency.
Principle of work of the present utility model and working process are: the first and second two reacting kettle jacketing cylindrical shells are by bottom conduit coupled in series, before feeding intake, close first reactor thermal oil bottom valve, filling heat-conductive oil in chuck, drop into diosgenin from manhole, add aceticanhydride and Glacial acetic acid from Auxiliary Liquid Material ingress, close all valves, be evacuated to vacuum tightness and reach more than the 0.08MPa, stop to vacuumize.The electric heater energising, give the jacket cylinder heat-conducting oil heating, when temperature in the kettle barrel reaches 160 ℃, open first reactor venting port valve, open the inlet mouth valve entrance pressure contracting air of second reactor, close other valves in the second reacting kettle jacketing, open successively second, first reactor thermal oil bottom valve with, stirred thermal oil 2 ~ 3 minutes by pressurized air, then close close successively first, second reactor thermal oil bottom valve with and the inlet mouth valve, then continue to be heated to the still internal pressure and reach 0.6MPa, open the valve of first reactor discharge nozzle, extrude material.
Before the reaction of first reactor finished, the work of getting ready in the second reactor dropped into saponin and aceticanhydride and Glacial acetic acid, and closes all valves.After the reaction of first reactor is complete, open successively second first reactor thermal oil bottom valve, then open the compressed air inlet port valve, close other valves in the first reacting kettle jacketing, thermal oil in the first reacting kettle jacketing all is pressed in the second reacting kettle jacketing, closes successively the first and second reactor thermal oil bottom valve valves, connect second reactor electric heater power supply, begin heating, other processes repeat first reactor operation steps can realize the purpose of this utility model.
The utility model is used for by the false diosgenin diacetate reaction of diosgenin ring opening synthesis, and the chuck oil temperature is even, has improved conversion rate of products, has greatly shortened reaction heat-up time and kettle cooling time, has saved electric energy.
