An integrated process industry dynamic process control experimental device

Abstract

The invention discloses an integrated experimental device for controlling a dynamic process of a flow industry, and relates to an experimental control device. The device consists of more than two resistance-capacitance water tanks, and a pipeline-free and valve-free integration mode is used for forming the experimental device for simulating dynamic characteristics of an object. A plurality of control system modes are configured for test. A controlled object of the experimental device is formed by integrating basic units which are resistance-capacitance links without pipelines or valves. The fluidic resistance of a throttling hole is regulated in a threaded seat cover way, and is changed from 0 to infinite to simulate a plurality of linear or nonlinear dynamic characteristics. The water tanks are provided with measurement transmitters respectively, a field indication rotor flow meter, a throttling hole plate, a control valve and a circulation water pump are arranged in four paths of water inlet pipelines respectively, and a pressure meter is arranged at an outlet of the water pump. The device can be used for a process control simulation experiment in flow processes of large chemical production devices, equipment and machines, fluid production devices, equipment and machines and the like, and is applied to the automatic teaching and scientific researches of colleges, scientific research institutions, training institutions, factories and the like as well as teaching.

Description

technical field [0001] The invention relates to an experimental device, in particular to an integrated process industry dynamic process control experimental device. Background technique [0002] At present, some of the controlled objects of the process control experimental device are simulated by the similar shape, simplified structure and reduced size of the actual industrial objects, such as rectification towers, neutralization reactors, heat exchangers and electric boilers. Its advantage is intuitive image, beautiful and beautiful stainless steel material, using five parameters (temperature, pressure, flow, liquid level, PH) to name various control system experiments, it seems very real, but it is proved that it is difficult to simulate the process more comprehensively The dynamic characteristics of various towers, kettles, furnaces, kilns, appliances and machines in the industry have great limitations and lack of flexibility in simulation. The problems are as follows: F...
