A multi-fluid intelligent batching control method

Abstract

The invention discloses a multi-fluid intelligent batching control method. The temperature, pressure and liquid level are monitored synchronously on the rectification tank, and the temperature of the fluid in the tank is adjusted through heat-conducting oil; the temperature, pressure and liquid level in the reaction tank are precisely controlled. Variation range; control the synchronization of liquid level, pressure and temperature in the finished product tank, mainly liquid level control, control the valves at the inlet and outlet to ensure constant temperature and pressure in the finished product tank; the reaction process in the reactor, comprehensively consider the temperature , flow, pressure, and liquid level, the software realizes the full-scale subsection fuzzy logic control through the logic operation function block, and converts the temperature deviation value into the flow deviation signal, which is used as the input side interference in the fuzzy logic control process The conditional effect or the difference input link that affects the main control flow parameters realizes the four-in-one synchronous and precise control of temperature, flow, pressure, and liquid level, ensuring the safety of the chemical reaction process.

Description

technical field [0001] The invention belongs to the technical field of fluid control, and in particular relates to a multi-fluid intelligent batching control method, through data mining, data analysis, and data processing of relevant process parameters in the chemical reaction process, so as to realize the intelligent optimization and coordination of the multi-fluid distribution process. Precise control of ingredient flow. Background technique [0002] At present, the multi-fluid intelligent batching system is in its infancy and development stage. With the development of industrialization and the optimization of industrial structure, it is imminent for enterprises to upgrade and transform their process production lines. At present, the control of the fluid valves of the batching system is mainly completed by manual operation. Since the production environment is mostly explosion-proof, not only higher quality requirements are put forward for the operators, but also there are...

[0003] In addition, the flow control in the prior art usually only depends on setting the set value and the safety threshold. After the sensor detects that the set value / safety threshold is reached, the valve is activated / closed. There is no more intelligent material control system and However, during the reaction process, the material does not change simply linearly, and some parameters change in real time. Therefore, the traditional method has low precision in simple regulation and cannot guarantee that the system material reaction is in an optimal state.
