Abstract
The utility model relates to a propiconazole bromination reaction automatic control system which comprises a bromination still. The propiconazole bromination reaction automatic control system is characterized in that a bromine dropping pipe is arranged on a still body of the bromination still. A flow adjustment valve is arranged on the bromine dropping pipe. A control mechanism of the flow adjustment valve is connected with a distributed control system (DCS). A temperature sensor and a pressure sensor are arranged on the still body of the bromination still. Output signals of the temperature sensor and the pressure sensor are connected with the DCS. When a bromination reaction is carried out, the flow adjustment valve turns on for a short time according to reset time of the DCS and then turns off, so a small amount of bromine enters the bromination still to initiate a reaction. Then the flow adjustment valve is controlled to turn on so as to evenly add the bromine in dropping mode. At the same time, the DCS controls the opening degree of the flow adjustment valve according signals output from the temperature sensor and the pressure sensor, and temperature of the reaction still can be maintained at 35 DEG C or slightly lower than 35 DEG C, and therefore reaction efficiency is improved on the basis of safety.
Description
Technical field
The utility model relates to a kind of propiconazole bromination reaction still, particularly a kind of propiconazole bromination reaction automatic control system.
Background technology
Propiconazole is a kind of interior absorption triazole bactericidal agent with protection and therapeutic action; Can be absorbed by root, stem, leaf portion, and can be soon in the plant strain body on conduction, the control sac fungus; The disease that basidiomycetes and Fungi Imperfecti cause; Particularly to take-all, powdery mildew, rust, root rot, water rice bakanae disease, sigatoka have the better prevention effect.
In the process of producing propiconazole, need in the cyclisation thing, drip bromine, generate bromine ketal and hydrogen bromide.During dropping, at first after the unlatching stirring, drip a small amount of bromine, initiation reaction evenly drips bromine then, and control still temperature dropwises to put into after the back is incubated 0.5 hour again and washes next technological process of still entering less than 35 ℃.Traditional method adopts the dropping of Artificial Control bromine; Its shortcoming is: operating personnel must stand in the aperture of other observation Pressure gauge that does not stop of bromination reaction still and the next corresponding control and regulation valve of thermometer; Need operating personnel's high concentration notice, labour intensity is big, has potential safety hazard.
Summary of the invention
The technical problem that the utility model will solve provides a kind of propiconazole bromination reaction automatic control system that reduces labour intensity and safety.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of propiconazole bromination reaction automatic control system; Comprise the bromination still; Its innovative point is: the kettle of said bromination still is provided with bromine and drips pipe, and said bromine drips on the pipe flow control valve is installed, and the controlling organization of said flow control valve inserts Distributed Control System; Temperature sensor and pressure sensor also are installed on the kettle of said bromination still, and the output signal of said temperature sensor and pressure sensor inserts Distributed Control System.
The advantage of the utility model is: when carrying out bromination reaction, close immediately after the of short duration unlatching of time that flow control valve is set according to Distributed Control System, make to get into a small amount of bromine and initiation reaction in the bromination still; And then control Flow-rate adjustment opening of valves evenly drips bromine; Simultaneously; Distributed Control System is controlled the aperture of flow control valve according to the signal of temperature sensor and pressure sensor output; Make the still temperature maintain 35 ℃ or be slightly less than in 35 ℃ the segment limit, thereby guaranteeing to improve reaction efficiency on the safe basis.
Description of drawings
Fig. 1 is the utility model propiconazole bromination reaction automatic control system structural representation.
The specific embodiment
As shown in Figure 1, comprise that bromination still 1, bromine drip pipe 2, flow control valve 3, temperature sensor 4, pressure sensor 5, Distributed Control System 6, discharge nozzle 7 and feed pipe 8.
The kettle top of above-mentioned bromination still 1 is provided with feed pipe 8, and this feed pipe 8 is communicated with the cyclization still of upper level, and autoclave body bottom is provided with discharge nozzle 7, and discharge nozzle 7 is communicated with the washing still of next technology.
Also be provided with bromine at the kettle top and drip pipe 2, this bromine drips on the pipe 2 flow control valve 3 is installed, and the controlling organization of flow control valve 3 inserts Distributed Control System 6.Temperature sensor 4 and pressure sensor 5 also are installed on the kettle of bromination still 1, and the output signal of temperature sensor 4 and pressure sensor 5 inserts Distributed Control System 6.
When carrying out bromination reaction, close immediately after the of short duration unlatching of time of flow control valve 3 according to Distributed Control System 6 settings, make a small amount of bromine get into initiation reaction in the kettle; Distributed Control System 6 is controlled flow control valve 3 again and is opened evenly dropping bromine then, and simultaneously, temperature sensor 4 is exported to Distributed Control System 6 with pressure sensor 5 with the signal that detects; Distributed Control System 6 is according to the aperture of controlling flow control valve 3; For example: during greater than 35 ℃, reduce the aperture of flow control valve 3 at temperature in the kettle, if temperature is less than 35 ℃ in the kettle; Then strengthen aperture, guaranteeing to improve reaction efficiency on the safe basis.
