Energy saving method for circulating water system

Abstract

The invention discloses an energy saving method for a circulating water system. The method comprises the following steps: firstly, detecting duty parameters of the current operation of the system andparameters of related devices; then, in accordance with the principle of economic operation of the circulating water system, creating a standard for the balance test and the calculation of the systemenergy by starting with a circulating water pump group, a pipe network, a heat-exchange device, a refrigeration device, a cooling tower and the like, analyzing the use efficiency of the system energy,evaluating the current use efficiency index of the system energy, and finding out the cause for the high energy consumption of the system; finally, by combining production process requirements, accurately finding out the optimum operating point where the devices are matched with the liquid transportation, and giving an optimum solution for the process energy of the system so as to achieve the purposes of high efficiency and energy saving. By detecting and analyzing the circulating water system, the invention provides a comprehensive, systemic and thorough energy saving method for the circulating water system.

Description

technical field [0001] The invention relates to an energy-saving method, in particular to an energy-saving method for a circulating water system. Background technique [0002] Water pumps are widely used in various fields of the national economy such as electric power, petroleum, chemical industry, metallurgy, environmental protection and municipal administration, and are one of the most important energy-consuming equipment, accounting for about 20% of the total power generation. Circulating water system such as figure 1 As shown, it is mainly composed of pump 1, transmission device 2, motor 3, power supply device 4, speed control device 5, suction pipeline 6, discharge pipeline 7, heat exchange equipment 8 and cooling tower 9, etc. Most circulating water systems have problems such as low efficiency and high energy consumption, which are mainly manifested in: 1) the design efficiency of water pumps and motors is low, and the manufacturing process is backward; 3) The design...

AI Technical Summary

Problems solved by technology

Most circulating water systems have problems such as low efficiency and high energy consumption, which are mainly manifested in: 1) the design efficiency of water pumps and motors is low, and the manufacturing process is backward; 3) The design and construction of the pipeline system are unreasonable, resulting in high local resistance and increased head loss; 4) Leakage of the pipeline system and water flow bypass increase the flow loss; 5) Frequent work changes of water pumps 6) The system cannot be scientifically scheduled according to the actual needs of the process, which increases power loss; 7) Improper operation and maintenance management, failure to replace spare parts in time, increases internal leakage loss
