Cloud intelligent control energy-saving system for unattended circulating water station

Abstract

The invention discloses an unattended circulating water station cloud intelligent control energy-saving system which is provided with a circulating loop jointly formed by a tail end heat exchange assembly, a cooling tower and a water pump assembly, and a cloud intelligent control platform is configured to generate first heat Q1 and second heat Q2 based on materials. Determining a first theoretical value of the heat exchange quantity Q4 of the tail end heat exchange assembly according to the third heat quantity Q3 of the heating agent or the cooling agent transferred to the equipment and the treated material; the actual water consumption H of the circulation loop is determined based on the temperature difference range of the circulation loop and heat exchanged by the tail end heat exchange assembly needed by material reaction; and determining working performance parameters of the water pump assembly based on the actual water consumption and the pipe network pressure difference. The reverse control mode is adopted, the real heat exchange amount and the water supply amount are calculated in real time through tail end process analysis, the water supply amount is accurately controlled, the whole system is real-time data, the tail end process changes, the water supply amount of the water supply end is fed back in time, and accurate water supply of the tail end is kept all the time.

Description

technical field [0001] The invention relates to the technical field of energy-saving systems, in particular to a cloud intelligent control energy-saving system for an unattended circulating water station. Background technique [0002] At present, the circulating water station (also known as the circulating water system) in the industrial field is a large energy consumer (electricity + water) and a large labor force of the energy consumption unit. It requires a large number of full-time personnel to manage and maintain, usually dozens to hundreds of people. There are more than 1,000 people, and the energy consumption also accounts for more than 20% of the entire factory. However, the technology and equipment of my country's current circulating water system are relatively backward, the degree of intelligence is low, and it is basically manual operation, the professional level of personnel is not high, the system maintenance is not in place, and the maintenance cost remains hig...

Problems solved by technology

Although this technology has a certain energy-saving benefit, the equipment has been updated, and the performance of the pump system has also been improved to a certain extent, but the energy-saving potential of the pump system is far from being tapped, and it does not involve other links except the pump system. The energy saving is not complete, and the power saving rate is generally 8% to 10%. There are a number of circulating water pump energy saving companies in China. The basic principle of energy saving is: through the development of professional testing tools, the current, voltage, water volume, pressure and other parameters of the pump system are tested in detail. , and then tailor-made high-efficiency energy-saving water pumps and high-efficiency motors according to the measured data, and replaced the old water pumps and motors with customized high-efficiency water pumps and high-efficiency motors. The power saving rate can generally reach 10-15%. The electricity rate can reach 20% (see patent: a new type of high-efficiency energy-saving water pump, patent number: ZL201821590903.X)

The common feature of the existing technologies is that the work is limited to the pump room, focusing on the pump system, without considering the energy saving of the whole process of the circulating water station, let alone the energy saving of the process optimization, energy saving of the management standard and the intelligent control of the whole process
