Embodiment

[0013] Example: such as figure 1 and figure 2 As shown, this embodiment provides a method for temperature control of the reactor, including two parts: the temperature-controlled reactor device and the specific implementation process of the temperature control of the reactor.

[0014] The temperature-controlled reactor equipment mainly includes the main component reactor, the important valve overflow valve, water inlet valve, exhaust valve and steam valve, and the auxiliary valve feeding valve and discharging valve. The important valve plays a key role in the control process of the whole system, and is used to control the temperature change of the reactor. Among them, the steam valve constitutes the control variable of the temperature control loop, and other valves assist in realizing the temperature control of the reactor.

[0015] The concrete realization steps of the temperature control method of reactor of the present invention are as follows:

Abstract

The invention discloses a temperature control method for a reaction kettle. An existing reaction kettle has no temperature automatic adjustment function and is incapable of automatically feeding back to a control system, and thus the system can not control the temperature of the existing reaction kettle well and ensure efficient and qualified products. According to the temperature control method for the reaction kettle, switchover between a proportion integration division (PID) control state and manual operation is set automatically through an actual temperature value. The temperature control method for the reaction kettle is characterized in that actual temperature is divided into different stratification, thus the purposes that different temperature is controlled by different PID control method, different PID control method has a different PID control parameter and a different regulating characteristic are achieved. According to the temperature control method, functions such as data collection, process identification, feedback mechanism and adjustment optimization are realized, the temperature control method for the reaction kettle has the advantages that the control of the actual temperature of the reaction kettle is accurate, manual operation is convenient and fast, products are qualified and certain degree of intellectualization is achieved.

Description

technical field [0001] The invention belongs to the technical field of industrial control, and in particular relates to a temperature control method for a reactor. Background technique [0002] At present, the temperature control of batch reactors is an important link in the industrial process. How to ensure the production of qualified products that meet market standards is a key issue that enterprises care about. The temperature control of the traditional reactor mainly relies on manual intervention, which requires a lot of manual operations, which has the problems of low efficiency, high labor costs, and untimely handling of system abnormal responses. The reactor does not have the function of automatically adjusting the temperature, nor does it have the ability to feed back to the control system independently, so the system cannot control the temperature of the reactor well to ensure efficient and qualified production of products. Although many advanced control method...
