Waste heat reutilization control system

Abstract

The invention aims to solve the problem of providing a scientific and efficient waste heat reutilization control system. The technical solution is that the waste heat utilization control system is mainly composed of a regulated power supply circuit, a relay state driving circuit, a pressure sensor constant-current power supply circuit, a pressure signal amplification circuit, a temperature signal input port, a temperature signal amplification circuit, a central controller operation oscillating circuit, a valve on-off state display circuit, a central control chip circuit, a three-way valve state control circuit, a reset circuit, an actuator control circuit and an A / D conversion voltage reference circuit; and the relay state driving circuit is electrically connected with the pressure signal amplification circuit, and the pressure sensor constant-current power supply circuit is electrically connected with the pressure signal amplification circuit. The waste heat reutilization control system has the beneficial effects that waste heat can be converted into other utilizable resources more efficiently and more reasonably, thereby achieving the purposes of saving energy, reducing emission, reducing the production cost, and increasing profits.

Description

Technical field [0001] The invention relates to the technical field of energy reuse, in particular to a waste heat reuse control system. Background technique [0002] In the process of industrial production, due to machine friction, cooling and other reasons, a large amount of waste heat will be generated. In the early stage, this waste heat will be directly discharged. In the near future, some enterprises will use this waste heat for heating and other environments. However, the utilization methods of these enterprises lack scientific and effective methods. In actual applications, considerable waste heat has caused losses, resulting in waste of resources and energy. In addition, the implementation of a single enterprise has its own specific environmental requirements and limitations, and is non-replicable and non-promotable. [0003] With the increase in energy costs year by year, the reuse of waste heat is gradually being valued by enterprises, but there is still a lack of scien...
