The rectification device comprises a rectification kettle and a rectification tower; heating media are connected onto the rectification kettle; a condenser is connected to an outlet of the rectification tower; a receiving tank, a water box and a backflow pipeline are connected onto the condenser; the backflow pipeline is used for communicating the condenser with the rectification tower; the rectification device is controlled by the DCS; and control points are respectively arranged 1 between the heating media and the rectification kettle, 2, between the condenser and the water box and 3, on a path of the backflow pipeline. By the aid of the design, the rectification device automatically controls operation process according to computer programs of different chemical materials and by mounting the DCS automatic control system, and effectively improves operation safety, thereby not only increasing rectification efficiency and saving resources, but also being capable of effectively ensuring automation of safety production.
Description
Technical field
The utility model relates to the fine chemistry industry separation field, realizes various fine chemistry industry batch fractionating operations by 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, but general automatic program is simple relatively, only design several steadiness parameters (as 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 (as temperature etc.), so just cause scale of investment big, operating condition is single.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide computer program and the installation DCS robot control system(RCS) of a kind of design at different chemical materials that the automation chemical industry batch fractionating device that automation is controlled is carried out in operating process.
The technical solution of the utility model is: the utility model comprises 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, described 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.
The utility model has the advantages that: the utility model carries out automation control at the computer program and the installation DCS robot control system(RCS) of different chemical materials to operating process by a kind of design, effectively improved processing safety, thereby not only improve rectification efficiency, economize on resources; And can effectively guarantee the automation of keeping the safety in production.Further the utility model is established warning device respectively on each different control points of DCS, in the time of can not accurately controlling to hinder for some reason as DCS, when causing rectifier unit not carry out rectifying according to predetermined parameters, warning device work this moment, remind 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 utility model
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 utility model comprises 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, described 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, the gas flow that evaporates 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 utility model is, earlier set various technical parameters according to the chemical material of rectifying in advance, realize a some control in real time by 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.
