The invention relates to an energy-saving regulating and control method and device of an industrial cooling water towering pump. In the invention, under the situation that the operation condition of the original industrial circulating cooling water is not changed, a communication pore is formed or a communication pipe is additionally arranged between a cold water pool and a hot water pool; a frequency converter is additionally arranged on the towering pump; a level instrument and a temperature transmitter are installed in the hot water pool and the cold water pool; a pressure transmitter is additionally arranged on the water outlet pipe of the towering pump; and the frequency converter, the level instrument and the temperature and pressure transmitters are connected to an energy-saving controller. In the invention, a pressure-guaranteed temperature-controlled level method is adopted to regulate and control the towering course of cooling water; and the water level height of the hot water pool or the water level height difference between the hot water pool and the cold water pool is automatically regulated and controlled according to the temperature of the hot water pool and the cold water pool, thereby automatically regulating and controlling the natural overflow rate through the communication pore or communication pipe according to the temperature of hot water and temperature of cold water required by the process, reducing the flow rate of the towering pump, and achieving the purpose of substantial energy saving and consumption reduction on the basis of satisfying the cooling process requirements.
Description
technical field [0001] The invention belongs to the technical field of industrial circulating cooling water, and in particular relates to an energy-saving control method and device for an upper tower pump of industrial cooling water. Background technique [0002] The industrial circulating cooling water system is a main cooling method widely used in thermal processing industries such as metallurgy, ceramics and building materials. The specific cooling process of the industrial circulating cooling water is that the water supply pump pressurizes the low-temperature cold water in the cold water pool to the process equipment. The low-temperature cold water absorbs the heat of the process equipment and turns into high-temperature hot water to return to the hot water pool after cooling, and then lifts the high-temperature hot water in the hot water pool to the cooling tower through the upper tower pump for forced air cooling, so that the heat of the high-temperature hot water can b...
