Abstract
The invention relates to a rectifying device which realizes various fine chemical batch rectifying operations by installing a DCS (distributed control system) automatic control system. The device comprises a rectifying tank, a rectifying tower, a heating medium connected to the rectifying tank, a condenser connected to the outlet of the rectifying tower, with the condenser connected with a receiving groove, a water tank and a backflow pipeline that communicates the condenser and the rectifying tower. The rectifying device is controlled by a DCS, and the control points are respectively arranged: 1) between the heating medium and the rectifying tank; 2) between the condenser and the water tank; 3) on the route of the backflow pipeline. By a computer program designed for different chemical materials and installation of the DCS automatic control system, the device of the invention realizes automatic control of the operation process, and effectively improves operation security, thus not only improving rectifying efficiency and saving resources, but also ensuring automation of safe production effectively.
Description
Technical field
The present invention relates to the fine chemistry industry separation field, realize various fine chemistry industry batch fractionating operations through the DCS robot control system(RCS) is installed specifically.
Background technology
Present general chemical industry rectifier unit branch: 1) the batch fractionating device generally all is to adopt the flow theory that the rectifying reflux ratio is realized control manually.Must carry out frequent control manually with each skill control parameter variation in this control procedure, so just bring the fatigability of operation and generally can not realize best skill control point operation, rectification efficiency is low, serious waste of resources; 2) though serialization rectifier unit part has realized automation, general automatic program is simple relatively, only designs several steadiness parameters (like temperature, pressure etc.); Technically; These parameters are constant, can not change with the variation of operating time, then must rely on equipment such as increasing rectifying column to satisfy if any wanting to change parameter (like temperature etc.); So just cause scale of investment big, operating condition is single.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide computer program and the installation DCS robot control system(RCS) of a kind of design to different chemical materials that the automation chemical industry batch fractionating device that automation is controlled is carried out in operating process.
Technical scheme of the present invention is: the present invention includes rectifying still, rectifying column; Be connected with heat medium on the rectifying still; The outlet of rectifying column is connected with condenser; The reflux line that is connected with groove, water tank on the condenser and is communicated with condenser and rectifying column, said rectifier unit is controlled by DCS, and each control point is separately positioned on: 1) between heat medium and the rectifying still; 2) between condenser and the water tank; 3) on the reflux line path.
The control point also comprises: 1) between rectifying still and the rectifying column; 2) between condenser and the groove; 3) between rectifying column and the condenser.
Be respectively equipped with warning device on each control point.
Advantage of the present invention is: the present invention carries out automation control to the computer program and the installation DCS robot control system(RCS) of different chemical materials to operating process through a kind of design, has effectively improved processing safety, thereby has not only improved rectification efficiency, economizes on resources; And can effectively guarantee the automation of keeping the safety in production.Further the present invention establishes warning device respectively on each different control points of DCS; With when the DCS failover can not accurately be controlled; When causing rectifier unit not carry out rectifying according to predetermined parameters, warning device work this moment reminds operating personnel in time to get rid of dependent failure; To guarantee accurately carrying out of rectifying, improve and respectively isolate the purity of heating up in a steamer thing.
Description of drawings
Fig. 1 is a structural representation of the present invention
1 is that heat medium, 2 is that rectifying still, 3 is that rectifying column, 4 is that condenser, 5 is that water tank, 6 is groove among the figure.
The specific embodiment
The present invention includes rectifying still 2, rectifying column 3; Be connected with heat medium 1 on the rectifying still 2; The outlet of rectifying column 3 is connected with condenser 4, the reflux line that is connected with groove 6, water tank 5 on the condenser 4 and is communicated with condenser 4 and rectifying column 3, and said rectifier unit is controlled by DCS; Each control point is separately positioned on: 1) between heat medium 1 and the rectifying still 2, with the parameters such as heating-up temperature, heat time heating time of control rectifying still 2; 2) between rectifying still 2 and the rectifying column 3, detect the evaporation capacity of rectifying still 2 gases and the flow of liquid with implementation; 3) between rectifying column 3 and the condenser 4, evaporate the gas flow that from rectifying column 3 with real-time detection; 4) between condenser 4 and the groove 6, to detect the amount of distillate; 5) between condenser 4 and the water tank 5, with the condensation temperature of control condenser 4; 6) on the reflux line path, with the amount of liquid of control backflow; Further on each control point, be respectively equipped with warning device.
The course of work of the present invention does; Earlier set various technical parameters according to the chemical material of rectifying in advance, realize some control in real time through each control point then, when technical staff's operate miss or on the DCS system breaks down; The warning device that is arranged on each control point is reported to the police; Pointing out which control point to go wrong, thereby can in the very first time, in time fix a breakdown, guarantee distillation process normally, accurately carry out.
