Intelligent heat conduction steam-water heat exchange dynamic temperature control method and dynamic temperature control system

Abstract

The invention discloses an intelligent heat conduction steam-water heat exchange dynamic temperature control method. The method comprises the following steps that (1) in the initial stage, the water level and water temperature are detected and compared with a preset water level value and a preset water temperature value respectively; (2) in the heat exchange stage, a heat source inlet and a heating power regulating valve are opened, a control device calculates and predicts time required by a water tank to reach a second preset temperature through an integral formula preset by the control device according to a flow meter, the environment temperature and the temperature of the water tank, and when the water temperature is approximate to the second preset temperature, the heating power regulating valve is closed in advance, and heat stored in a heat exchanger is used for continuously heating the water tank so that the water temperature can reach the second preset temperature. The invention further discloses a dynamic temperature control system. The intelligent heat conduction steam-water heat exchange dynamic temperature control method solves the problem that an ordinary thermostat only detects the water temperature to keep a constant temperature, so internal heat is dissipated or absorbed continuously, the water temperature fluctuates, and response is retarded; the heat source state, the temperature of the water tank and the surrounding environment temperature are synthesized, time required by heating is predicted, accurate control is achieved, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of steam condensation heat exchange and water tank water temperature constant temperature control, in particular to a heat conduction intelligent steam-water heat exchange dynamic temperature control method and a dynamic temperature control system implementing the method. Background technique [0002] With the development of electronic technology, automatic control applications have become more flexible and diverse. Although there are many devices that can realize constant temperature control. Aiming at the heat recovery of waste steam from the autoclave and the precise control of the water temperature, and considering the safety and intelligence, there are very few equipments for constant temperature control of the system from the perspective of thermodynamics. [0003] The general constant temperature box only detects the water temperature, and then adjusts the water temperature to achieve a constant temp...

Problems solved by technology

To make matters worse, part of the outlet of the heat exchanger is directly emptied, and the latent heat of vaporization of a lot of steam that is too late to condense is wasted in the atmosphere.
