Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described:
Fluid-tight distillation equipment, comprise distillation still 1, described distillation still 1 is connected with king-post 3 by evaporation tube 2, the top of king-post 3 is provided with liquid seal device 4, the top of liquid seal device 4 is provided with condenser 5, described liquid seal device 4 and condenser 5 Flange joint, condenser 5 is tightly connected by vacuum tube 6 and front fractionation accumulator tank 7, vavuum pump unit 8, the side of described liquid seal device 4 is provided with the discharge nozzle 10 with valve first 9, discharge nozzle 10 and feed liquid receiving slit 11 are tightly connected, and described feed liquid receiving slit 11 seals the blow-down pipe 13 be provided with valve second 12; The interlayer of described condenser 5 connects and composes closed circuit by oil pipe first 14 and Heat preservation slot device first 15; The interlayer of described discharge nozzle 10 and the interlayer of vacuum tube 6 connect and compose closed circuit by oil pipe second 16 and Heat preservation slot device second 17.
Described liquid seal device 4 is provided with liquid distributor 18 and feed liquid receiver 19, and liquid distributor 18 is fixedly connected with condenser 5 by ring flange, and the base of described feed liquid receiver 19 is fixedly connected with king-post 3 by transverse slat support 20.
Described liquid material distributor 18 is the hemispherical container with mesh 21.
The diameter of described mesh 21 is 2cm.
Distillage is often very high to temperature requirement, so the present invention respectively forms structure all with interlayer, utilizes conduction oil to ensure the temperature in each stage.
The in indicated in Fig. 1 is that supervisor's oil in the finger external world returns, and out is that supervisor's oil in the finger external world enters, and is used for by delivered heat to the conduction oil in Heat preservation groove first 24 and Heat preservation groove second 26, controls the conduction oil temperature in Heat preservation groove by this way.
Working environment of the present invention is vacuum environment, first utilizes vavuum pump unit 8 to vacuumize, until the show value of display list reaches 980mmHg.Subsequently, from charging aperture 22, material is rendered in distillation still 1, utilize the conduction oil in chuck that distillation still 1 is heated up gradually, stop heating up when the temperature of distillation still 1 reaches 220 DEG C.
In the process that temperature constantly rises, material melts gradually and arrives vaporization again, and gas flows to king-post 3 through evaporation tube 2, arrives at condenser 5 through king-post 3 and liquid seal device 4.The temperature of condenser needs to control below the fusing point of distillage, that is to ensure that the temperature of condenser will lower than the fusing point of distillage, condenser 5 connects and composes closed circuit by oil pipe first 14 and Heat preservation slot device first 15, the circulating pump first 23 of Heat preservation slot device first 15 drives the insulation oil shuttling movement of Heat preservation groove first 24, regulate the temperature of extraneous supervisor's oil to regulate the conduction oil temperature in Heat preservation groove first 24 as required, make the temperature in Heat preservation groove 24 meet condenser 5 temperature required.Gas is liquefied as liquid through condenser 5, and liquid flows out from the mesh of liquid distributor 18, in instillation feed liquid receiver 19.Feed liquid after such rectifying is just collected in feed liquid receiver 19 and discharge nozzle 10, flows in feed liquid receiving slit 11 through discharge nozzle 10.Discharge nozzle 10 is band insulating tubes with dissection, the temperature of discharge nozzle 10, vacuum tube 6 needs higher than the fusing point of distillage 10 DEG C-15 DEG C, the interlayer of discharge nozzle 10 and the interlayer of vacuum tube 6 connect and compose closed circuit by oil pipe second 16 and Heat preservation slot device second 17, equally by regulating the oily conduction oil temperature regulated in Heat preservation groove second 26 of extraneous supervisor, again through the effect of circulating pump second 25, guarantee that discharge nozzle 10 and vacuum tube 6 reach the temperature requirement of specifying.
If midway needs sampling, directly open valve first 9, feed liquid flows in feed liquid receiving slit 11, and valve-off first 9, prevents air to be mixed into, and opens the valve second 12 be arranged on blow-down pipe 13 subsequently, directly samples in feed liquid receiving slit 11.So just, make use of fluid-tight principle effectively prevents air to be mixed into, and solves the problem that legacy equipment exists explosion safety hidden danger.
Above-mentioned, be only preferred embodiment of the present invention, be not used for limiting scope of the present invention, all equalizations of doing according to the form described in the claims in the present invention scope, structure, feature change and modify, and all should be included in right of the present invention.
