Abstract
The utility model discloses an automatic control device for sulphonating para-phenetidine, comprising a temperature transmitter, a programmable logic controller, a freezing salt water valve and a charging valve, wherein the temperature transmitter, the freezing salt water valve and the charging valve are connected with the programmable logic controller; the temperature transmitter, the freezing salt water valve and the charging valve are also connected with a sulphonation reaction kettle, the temperature of the sulphonation reaction kettle is detected by the temperature transmitter and the temperature parameter is transmitted to the programmable logic controller, the freezing salt water valve and the charging valve are respectively controlled by the automatic adjustment of the programmable logic controller to adjust the flow amount of the freezing salt water and the charging speed to stabilize the temperature in the sulphonation reaction kettle. The sulphonation reaction is automatically controlled by the programmable logic controller, the charging speed of the para-phenetidine and the flow amount of the freezing salt water are adjusted by the variation in the reaction temperature, thus the sulphonation reaction temperature is stabilized in the preset range of the technology.
Description
Technical field
The utility model relates to the intermedium production technology of a kind of synthetic dyestuffs and surfactant, particularly a kind of automatic control device that is used for the paraphenetidine sulfonation.
Background technology
The paraphenetidine sodium sulfonate is the intermedium of one type of synthetic dyestuffs and surfactant, in industry such as dyestuff, auxiliary agent, medicine, agricultural chemicals, is widely used.The process for sulfonation that adopts when the paraphenetidine sodium sulfonate is produced is: paraphenetidine and oleum carry out sulfonating reaction; Because the requirement of technology; This sulfonating reaction must be carried out at low temperature (≤40 ℃); Because it is sulfonating reaction is the reaction of a fierceness,, heavy then can cause that subsidiary reaction is until causing accident hazard if temperature drift gently then can cause product quality bad.
The existing device of producing paraphenetidine all is by control manually; The instrument non-productive operation; Because the manually-operated labile factor is more, especially the man-induced fluctuations factor is bigger on links such as material metering, charging rate, temperature of reaction, reaction pressure, reaction time, and products obtained therefrom shows that mainly outward appearance, active matter content and stable aspect are all inadequate; Thereby bigger to the quality influence of product, become the present problem demanding prompt solution of dealer of association area.
The utility model content
The utility model technical matters to be solved provides a kind of automatic control device that is used for the paraphenetidine sulfonation; It has carried out automatic control through programmable logic controller to sulfonating reaction; Regulate the charging rate of paraphenetidine and the flow of chilled brine through the variation of temperature of reaction, make the sulfonating reaction temperature stabilization in the scope of process stipulation.
For solveing the technical problem; The utility model provides a kind of automatic control device that is used for the paraphenetidine sulfonation; It is characterized in that; It comprises temperature transmitter, programmable logic controller, chilled brine valve, charging valve; Temperature transmitter, chilled brine valve, charging valve all are connected with programmable logic controller, and temperature transmitter, chilled brine valve, charging valve also are connected with a sulfonating reaction still, and temperature transmitter detects the temperature of sulfonating reaction still and sends temperature parameter to programmable logic controller; Chilled brine valve and charging valve are controlled in automatic adjustment via programmable logic controller respectively, make the temperature stabilization in the sulfonating reaction still with the flow and the charging rate of regulating chilled brine.
The positive progressive effect of the utility model is: the utility model has carried out automatic control through programmable logic controller to sulfonating reaction; Regulate the charging rate of paraphenetidine and the flow of chilled brine through the variation of temperature of reaction; Make the sulfonating reaction temperature stabilization in the scope of process stipulation, ensure safety in production and product quality.
Description of drawings

As shown in Figure 1; The automatic control device that the utility model is used for the paraphenetidine sulfonation comprises temperature transmitter 2, programmable logic controller 4, chilled brine valve 5, charging valve 6; Temperature transmitter 2, chilled brine valve 5, charging valve 6 all are connected with programmable logic controller 4; Temperature transmitter 2, chilled brine valve 5, charging valve 6 also are connected with a sulfonating reaction still 1; Temperature transmitter 2 detects the temperature of sulfonating reaction still 1 and sends temperature parameter to programmable logic controller 4; Control chilled brine valve 5 and charging valve 6 respectively via the automatic adjustment of programmable logic controller 4, make the temperature stabilization in the sulfonating reaction still 1 with the flow and the charging rate of regulating chilled brine.
Earlier add quantitative oleum, open the chilled brine valve and add chilled brine, open and stir at the sulfonating reaction still.Open automatic control device, when reactor temperature is reduced to below 30 ℃, open the charging valve and the chilled brine valve of paraphenetidine automatically, regulate the size and reinforced speed of chilled brine according to temperature automatically, until reinforced finishing.After this in 40 ± 2 ℃ of insulation reaction end in four hours continuously down of temperature.
In sum; The utility model has carried out automatic control through programmable logic controller to sulfonating reaction; Regulate the charging rate of paraphenetidine and the flow of chilled brine through the variation of temperature of reaction; Make the sulfonating reaction temperature stabilization in the scope of process stipulation, ensure safety in production and product quality.
The foregoing description is the principle and the effect thereof of illustrative the utility model only, but not is used to limit the utility model.Any be familiar with this technological personage all can be under the spirit and category of the utility model, the foregoing description is modified or is changed.Therefore, have common knowledge the knowledgeable under such as in the technical field, must contain by the claim of the utility model not breaking away from all equivalence modification or changes that spirit that the utility model discloses and technological thought are accomplished down.
