Description
Technical field
The utility model belongs to the refining purification technique of fine chemical product, specifically is a kind of real-time discharge system under the high vacuum rectification condition.
Background technology
The material that material through the chemical industry rectifying separation generally includes has a variety of, and isolated every kind of material will be installed corresponding receiving vessel usually and receives in the distillation process, and what of receiving vessel are according to how many decisions of component of material.Therefore receiving vessel not of uniform size can occupy either large or small locus in industry spot.Existing many, the assorted situation of industry spot Space Facilities that solve mostly are through pump material to be transferred to finished product storehouse container perhaps to solve through the packaged type container.
But the material under high vacuum condition shifts, and product pump can have influence on the stability that system produces owing to influencing the system vacuum operating condition in the process that outside system, shifts material.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned existence, a kind of simple in structure, easy and simple to handle, on-the-spot temporary receiving vessel of minimizing rectifying separation material component is provided, real-time discharge system under the high vacuum rectification condition of reduction fixed investment.
The technical scheme that the utility model is adopted to achieve these goals is following:
A kind of under the high vacuum rectification condition real-time discharge system; It comprises intermediate storage tank, three liquid-level switches, magnetic valve and product pumps; Wherein magnetic valve comprises magnetic valve A and magnetic valve B; It is characterized in that said three liquid-level switches are successively set on from top to bottom on the intermediate storage tank and connect magnetic valve A, product pump and magnetic valve B respectively; The lower end outlet conduit of intermediate storage tank connects product pump, and said magnetic valve A is arranged between intermediate storage tank and the product pump, and magnetic valve B is arranged between product pump and the finished container.
The technical scheme that is more preferably in the utility model is that said liquid-level switch adopts Fork LIquid Level Switch, and magnetic valve B is identical with the material component quantity of product pump outlet
The utility model can effectively solve the unstable problem of discharging of high vacuum rectification system; Significantly reduce the on-the-spot temporary receiving vessel of rectifying separation material component; Reduce fixed investment, therefore have advantages such as simple in structure, with low cost, handled easily, can make and improve Enterprises'Competitiveness effectively.

Among the figure: 1-intermediate storage tank, 2-liquid-level switch, 3-magnetic valve A, 4-magnetic valve B, 5-product pump.
The specific embodiment
Further specify below in conjunction with the technical scheme of accompanying drawing the utility model,
As shown in Figure 1: a kind of under the high vacuum rectification condition real-time discharge system, it comprises intermediate storage tank 1, three liquid-level switches 2, magnetic valve and product pumps 5, wherein magnetic valve comprises magnetic valve A3 and magnetic valve B4.Said three liquid-level switches 2 are successively set on the intermediate storage tank 1 from top to bottom and connect magnetic valve A, product pump 5 and magnetic valve B respectively; The lower end outlet conduit of intermediate storage tank 1 connects product pump 5; Said magnetic valve A3 is arranged between intermediate storage tank 1 and the product pump 5, and magnetic valve B4 is arranged between product pump 5 and the finished container.
Outlet conduit connects one of product pump under the discharging intermediate storage tank of distillation system, and three liquid-level switches are installed on the discharging intermediate storage tank, the start and stop and the fault judgement of control product pump, and the High High Level fault alarm, the high-order startup, low level stops.Cut off with magnetic valve A in the middle of discharging intermediate storage tank and the product pump, cut off with magnetic valve B in the middle of product pump and the finished container, high speed discharging stage magnetic valve A and magnetic valve B open, and material is closed magnetic valve A and magnetic valve B after shifting and finishing automatically.
As shown in Figure 2: native system has adopted DCS system one cover, one of magnetic valve, and one of product pump, three of Fork LIquid Level Switch, magnetic valve B is some.Wherein what of magnetic valve B are provided with the corresponding magnetic valve B of each material according to what of material component.When Fork LIquid Level Switch was flooded corresponding tuning fork in liquid level, output switching signal got into the DCS system, and the DCS system sends command adapted thereto control magnetic valve A, magnetic valve B and product pump work and stops.Before system puts into operation, debug system, when the high speed discharging was set, magnetic valve A left earlier, lagged behind to start product pump in three seconds, and three seconds opens solenoid valve B again lag behind; When stopping discharging, magnetic valve A closes earlier, and lagging behind stopped product pump in 3 seconds, lagged behind and closed magnetic valve B in three seconds.When high level switch lost efficacy, the alerting that can send warning signal of superelevation liquid-level switch.During this high vacuum rectification system works, gaseous phase materials gets into separator through becoming liquid state after the condenser condenses, except that a part of feed back to rectifying column, all the other flow into discharging intermediate storage tanks.The material liquid level is when flooding too high liquid level tuning fork, and the DCS system sends instruction, and control magnetic valve A opens, and starts product pump then, opens corresponding solenoid valve B again.Discharging intermediate storage tank material shifts when finishing, and the low level Fork LIquid Level Switch is sent corresponding signal to the DCS system, and the DCS system sends the signal that magnetic valve A closes immediately, stops discharging pump, closes magnetic valve B, and original state is replied by system, waits for discharging next time.
