Description
Technical field
The utility model relates to the intermittent production equipment technical field of chemical industry, is specifically related to a kind of vacuum distillation system.
Background technology
In vacuum distillation system, we need to carry out sampling to the cut distilled out and detect, and just need pipeline after the condenser adds sample tap.Sample tap is in the past a downward sample tap, when sampling by the upper valve open of sample tap, material is entered in short circuit head, then valve open lower valve is closed in pass, samples at lower valve with sampling bottle.Such method shortcoming is that the inventory had in pipeline is larger, releasing a large amount of material, then receive with sampling bottle, causing, when sampling, water clock occurs, if when the toxic, excitant, volatility, smell etc. of special material are larger, easily cause the working environment of workman to become very poor.For the product of costliness, certain loss can be caused.
In the material process that distillation is a large amount of, a storage tank is not enough, needs to change storage tank in still-process.Need the valve of closing outlet during replacing, and change within the extremely short time, execute-in-place inconvenience, poor stability.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of vacuum distillation system easy to use.
For solving the problem, technical solution adopted in the utility model is:
A kind of vacuum distillation system, it comprises reactor, the condenser be connected with reactor and the reception storage tank be connected with condenser by tube connector and stand-by storage, described tube connector is provided with the first threeway for sampling and for switching the second threeway receiving storage tank;
The supervisor two ends of described first threeway are provided with the first valve and the second valve, and the arm of the first threeway is provided with the 3rd valve, the first threeway is horizontally disposed with, and described 3rd valve openings upward;
Described second threeway one end is connected with the first valve or the second valve, and all the other two ends are connected with reception storage tank and stand-by storage respectively;
Described reception storage tank is connected with vacuum generator by pipeline with stand-by storage.
As further improvement of the utility model, the tube connector of one section of level is set between the first described threeway and condenser, this tube connector is provided with visor.
The beneficial effect adopting technique scheme to produce is:
The utility model is by arranging the first threeway, and the first threeway is horizontally disposed with, arm is opening up, when needs sample time, first closing the valve near receiving storage tank, making in pipeline, to store a certain amount of material, then the valve near condenser is closed, in the supervisor of the first threeway, store a certain amount of material like this, then open the 3rd valve, sampled by sampling bottle or suction pipe.In sampling process, only have the small part material in the supervisor of the first threeway to expose in the environment, a large amount of materials of reactor and reception storage tank are in air-tight state, and the arm mouth of pipe of the first threeway upward, can not cause the water clock of material.Therefore, all can not impact for reaction system and external environment condition, security is high.
Arrange the second threeway and stand-by storage, after reception storage tank material is filled, directly carried out the switching of storage tank by the valve be arranged in the second threeway, simple and efficient to handle, security is high.
The setting of visor can make operating personnel see the storage capacity of material in pipeline, and carry out the opening and closing operations of valve according to the amount of material, accuracy is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 reactor, 2 condensers, 3 first threeways, 4 first valves, 5 second valves, 6 the 3rd valves, 7 vacuum generators, 8 receive storage tank, 9 visors, 10 second threeways, 11 the 4th valves, 12 the 5th valves, 13 stand-by storages.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, utility model is described in further detail:
A kind of vacuum distillation system as shown in Figure 1, it comprises reactor 1, the condenser 2 be connected with reactor and the reception storage tank 8 be connected with condenser 2 by tube connector and stand-by storage 13, described tube connector is provided with the first threeway 3 for sampling and for switching the second threeway 10 receiving storage tank; The arm that the supervisor two ends of described first threeway 3 are provided with the first valve 4 and the second valve 5, first threeway 3 is provided with the 3rd valve 6, first threeway 3 be horizontally disposed with, described 3rd valve 6 is opening up; Described second threeway 10 one end is connected with the second valve 5, and all the other two ends are connected with reception storage tank 8 and stand-by storage 13 respectively; Described reception storage tank 8 is connected with vacuum generator 7 by pipeline with stand-by storage 13.
The tube connector of one section of level is set between the first described threeway 3 and condenser 2, this tube connector is provided with visor 9.
In the present embodiment, described second threeway 10 Single port is connected with the second valve 5, the downstream that all the other two-port arrange the 4th valve 11 and the 5th valve the 12, four valve 11 is respectively connected with reception storage tank 8 by tube connector, and the downstream of the 5th valve 12 is connected with stand-by storage 13 by tube connector.
Receive storage tank 8 and stand-by storage 13 and the connecting line of vacuum generator 7 also arranged corresponding by-pass valve control (scheming not shown), for coordinating the switching of storage tank.
In the process of vacuum distillation, as need sampling operation be carried out, first close valve downstream (the second valve 5) near sample tap (the 3rd valve 6), stockpile in making material in supervisor's (straight tube) of the first threeway 3, closing upstream valve (the first valve 4) makes sampling area depart from vacuum system, slow unlatching the 3rd valve 6 makes it balance to atmospheric pressure, with a fine rule, sampling bottle is hung in sampling pipe, the 3rd valve 6 is closed successively after sampling, open upstream valve downstream, proceed still-process.Whole sampling process does not destroy former vacuum system, does not produce the evaporating, emitting, dripping or leaking of liquid or gas of material.
Valve described in the present embodiment all can adopt ball valve.The application is by the ingenious setting to three-way device and valve installation position, both the problem that sampling in vacuum distillation system is inconvenient, easily cause material water clock, contaminated environment had been solved, also the problem changed in still-process and receive storage tank inconvenience can be solved, therefore, the technical scheme that the application provides is overall, easy to use in vacuum distillation process, greatly reduce the operation easier of operating personnel, and there is better security.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in previous embodiment, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of the utility model embodiment technical scheme.
