Abstract
The utility model relates to an automatic liquid phase separation control system, which comprises a separating tank, a water pump and a control valve, and a water phase outlet of the separating tank is connected with the water pump and the control valve in sequence. The control system has main technical characteristics that the separating tank is also connected with an acidometer, the probe of the acidometer is mounted in the separating tank, the output end of the acidometer is connected with the data collecting end of a PID controller, and the control end of the PID controller is connected with the control valve. In the utility model, the automatic control function of the liquid phase separation under the unstable condition is fulfilled by adding the acidometer and the PID controller, the realization method is simple, and the application range is extensive; and moreover, the control system avoids the easy occurrence of errors in the manual operation, thereby improving the separation effect and work efficiency.
Description
Technical field
The utility model belongs to the liquid separation technology field, especially a kind of liquid phase separation automatic control system.
Background technology
In chemical process, often need utilize the difference in specific gravity of two kinds of non soluble liquids to carry out the phase-splitting separating treatment.For example, in the naphthalene recycling process that bisnaphthol is produced, naphthalene need be sent in the knockout drum with the mixed liquor of alkaline water naphthalene is separated with alkaline water.Existing isolation technics is when carrying out separating treatment, usually adopt the manual mode of operation or adopt fixing pattern and condition to carry out, if the component ratio of continuous feed is stable inadequately, under the unfixed again situation of pressure of discharging simultaneously, be difficult to stable or liquid phase separation exactly, and occur bust easily, influenced separating effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of reasonable in design is provided, can realizes automatic separating treatment under various conditions, improves the liquid phase separation automatic control system of separating effect.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of liquid phase separation automatic control system, comprise knockout drum, water pump and by-pass valve control, the water outlet of knockout drum is connected successively with water pump and by-pass valve control, knockout drum also connects an acidometer, the probe of this acidometer is installed in the knockout drum, the output of this acidometer is connected with the data acquisition end of PID controller, and the control end of this PID controller is connected with by-pass valve control.
And described acidometer adopts the 40A holding wire to be connected with the PID controller, and the PID controller adopts the 40A holding wire to be connected with by-pass valve control.
And that described acidometer adopts is LP-8016, and that described by-pass valve control adopts is SDDF-D-X.
Advantage of the present utility model and good effect are:
1. this automatic control system has made full use of the acidity difference between two kinds of unstable liquid phases, detect the acid-base value in the knockout drum in real time and testing result exported to the PID controller by acidometer is installed, carry out the automatic adjusting of water output by PID controller by-pass valve control, realized the automation separating treatment function of liquid phase under instability condition, the problem of avoiding manually-operated to go wrong easily improves separating effect and operating efficiency.
2. this automatic control system implementation method is simple, has captured the difficult problem that two kinds of immiscible unstable liquid phases realize separating substances, can be used for the separating treatment field of all organic facies that acidity and difference of specific gravity are arranged and water.
3. the utility model has been realized the automatic control function of liquid phase separation under instability condition by increasing acidometer and PID controller, its implementation is simple, the scope of application is extensive, the problem of having avoided manually-operated to go wrong easily improves separating effect and operating efficiency.
Description of drawings
Fig. 1 is a system of the present utility model connection diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
A kind of liquid phase separation automatic control system as shown in Figure 1, is connected and composed by knockout drum, acidometer, PID controller, water pump and by-pass valve control, and the water outlet of knockout drum is connected successively with water pump and by-pass valve control.Knockout drum also is connected with acidometer, and its connected mode is: the probe of acidometer is installed in the interface place that sets in the knockout drum.The output of acidometer is connected with the data acquisition end of PID controller and realizes the real-time detection and the output of meter several times, the control end of this PID controller is connected with by-pass valve control, the PID controller is handled the real-time testing result of acidometer, and result is passed through the control of its control end realization to by-pass valve control.In the present embodiment, between described acidometer and the PID controller be connected and PID controller and by-pass valve control between be connected and all adopt the 40A holding wire to be connected, wherein, what acidometer adopted is the LP-8016 model, and what by-pass valve control adopted is the SDDF-D-X autocontrol valve.
Operation principle of the present utility model is: the probe of acidometer is reached the interface place that sets in the knockout drum, the pH value that detects liquid when acidometer is greater than 9 the time, then acidometer is to PID controller output index signal A, the PID controller is handled the back and is sent increasing aperture signal to by-pass valve control, increases water yield; When the detected pH value of acidometer less than 8 the time, then acidometer is to PID controller output index signal B, the PID controller is handled the back and is sent to by-pass valve control and reduce the aperture signal, reduces water yield.This mode interlocks in autocontrol valve acidometer by the PID controller, realize that automation is unattended, has guaranteed the stable separation of liquid phase.
Present embodiment is illustrative; rather than it is determinate; therefore can not limit protection domain of the present utility model according to this, every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to the scope of the utility model protection equally.
