Description

A kind of solution concentration on-line monitoring and control system and method
Technical field
The present invention relates to a kind of solution concentration on-line monitoring and control system and method, especially can on-line monitoring solution concentration also immediately make the control system method of feedback.
Background technology
Because some solution can decompose generate other materials in transportation, cause the concentration that wish is led to the mixed solution of equipment to change, but also cannot on-line monitoring and carry out this solution of accurate quantification, thereby have a strong impact on product effect.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned existence, provide a kind of and can realize on-line monitoring and can reach the system and method to this solution accurate quantification by on-line monitoring instrument and volume pump.
Solution concentration on-line monitoring and a control system, is characterized in that it includes:
Two pipeline parallel connections, are specially the labile solution line of solute and the stable solution line of solute;
One line mixer, together connects with line mixer after two described pipeline parallel connections;
The labile solution on-line monitoring of one solute instrument, described line mixer is connected with the labile solution concentration on-line monitoring of solute instrument;
One volume pump, the probe of the labile solution on-line monitoring of described solute instrument is connected with the volume pump of installing on the labile solution line of solute again.
In motor in described volume pump, be provided with toggle.
In described toggle, slide bar is directly connected with diaphragm.
On described metering pump head, be provided with the retaining valve of controlling suction by keying.
Described on-line monitoring instrument structure is that controller, stube cable, sensing head are connected successively with mounting adapter.
Solution concentration on-line monitoring and a control method, comprise the following steps: the content that A, the labile solution on-line detector of solute import all solutes in the mixed uniformly solution detecting in line mixer according to the labile solution of solute and the stable solution of solute demonstrates reading and sends analog quantity output signals;
B, this current signal immediate feedback to volume pump for regulating the instantaneous delivery of the stable solution of solute, thereby guarantee that the concentration of the labile solution of solute in the solution of the equipment that flows to can be controlled in the scope of technological requirement.
The invention has the beneficial effects as follows: 1, can realize on-line monitoring aborning, highly sensitive; 2, can enhance productivity to greatest extent and guarantee product quality simultaneously; 3, realize the production automation.
Accompanying drawing explanation
Fig. 1 is the labile solution testing process of solute schematic diagram.
Fig. 2 is the principle schematic of the easy decomposing solution on-line monitoring of solute instrument.
Embodiment
As shown in Figure 1: this on-line monitoring solution concentration control system is by the labile solution line of solute and the stable two pipeline parallel connections of solution line of solute, then together connect with line mixer, connect with the labile solution concentration on-line monitoring of solute instrument again, now the probe of the labile solution on-line monitoring of solute instrument is connected with the volume pump of installing on the labile solution line of solute again, thereby------line mixer---the labile solution on-line monitoring of solute instrument---volume pump is controlled the closed-loop path of the pipeline of the labile solution of solute to the solution line that solute is stable to form a labile solution line of volume pump control solute.The content that the labile solution on-line detector of solute imports all solutes in the mixed uniformly solution detecting in line mixer according to the labile solution of solute and the stable solution of solute demonstrates reading and sends analog quantity output signals, this current signal immediate feedback to volume pump for regulating the instantaneous delivery of the stable solution of solute, thereby guarantee that the concentration of the labile solution of solute in the solution of the equipment that flows to can be controlled in the scope of technological requirement.
On-line monitoring instrument structure as described in as shown in Fig. 2 is that controller, stube cable, sensing head are connected successively with mounting adapter.
In system operational process, we establish the labile solution of solute is first solution, and the stable solution of solute is second solution, and all solute stabilizing solution concentration all-the-time stable are constant except the easy decomposing solution of solute.When system boot, with on-line detector, detect supplied materials first and second solution concentration, be designated as initial value.In the time of first solution on-line monitoring instrument energy instant playback supplied materials solution concentration value, this concentration value is transferred to volume pump, according to conversion relation, calculate the amount that need to add first solution, motor in the volume pump of now installing on first solution line drives worm couple to do variable motion by direct-connection transmission, under the effect of toggle, will rotatablely move and change linear reciprocating motion into.Slide bar is directly connected with diaphragm, directly pushes away (drawing) dynamic diaphragm during slide bar to-and-fro movement and agitate back and forth during work, by the retaining valve keying effect on pump head, completes suction object, reaches the function of carrying the first solution that meets technological process and accurate measurement.First solution on-line detector demonstrates reading and sends analog quantity output signals according to the content of all solutes in the solution detecting in first solution and second solution remittance line mixer, this current signal immediate feedback is used for regulating the instantaneous delivery of first solution to volume pump, now the first solution of accurate quantification and second solution are through line mixer through evenly mixing and reach the requirement of technological process, and the equipment that can directly flow to is used.
