Embodiment Construction
[0061] Below in conjunction with accompanying drawing and by embodiment the present invention will be further described:
[0062] The circulating cooling water system of a 30,000 tons of aniline and 50,000 tons of nitrobenzene production equipment, such as figure 1 . The system has two GBNF-800 cooling towers, equipped with three parallel circulating water pumps, the model is 350S44A, two are running and one is standby. Single pump flow rate 1116m 3 / h, head 36m, speed 1450r / min. The water pump is equipped with a Siemens Y315L-4 motor with a rated power of 160kW, a rated current of 288A, a motor efficiency of 91.9%, and a rated speed of 1486r / min. The equipment is distributed by layers, and the system is equivalent to five parallel heat exchange user groups, among which the first, second, and third layers of each layer are connected in parallel. There are three devices on the fourth floor, the two devices at the second highest point are connected in parallel, and the devic...

An industrial recirculating-cooling-water-system annual average cooling energy efficiency ratio energy consumption integration evaluation index and a method thereof belong to the industrial energy saving and emission reduction technology field. In the invention, a recirculating-cooling-water-system cooling energy efficiency ratio and an annual average cooling energy efficiency ratio are provided and a calculating formula is given out. Different energy consumption indexes of a plurality of conditions of a recirculating cooling water system under a certain environment are calculated, compared and analyzed. The annual average cooling energy efficiency ratios of a whole year in a plurality of schemes of the recirculating cooling water system are calculated and compared. Through theorical analysis and an example, the annual average cooling energy efficiency ratio can comprehensively reflect energy consumption and energy utilization conditions of each link of the industrial recirculating cooling water system in all the periods of the year, is the energy consumption integration evaluation index and is used for reasonably evaluating an industrial recirculating cooling water system energy consumption condition. A principle and a method of determining an industrial recirculating cooling water system energy efficiency rate and an acceptance standard are provided. The invention provides the annual average cooling energy efficiency ratio energy consumption integration evaluation index and the method, a design and an operation level of the industrial recirculating cooling water system can be increased, and system energy consumption and operation cost are greatly saved.
Description
technical field [0001] The invention relates to an industrial energy consumption evaluation index and method, in particular to an industrial circulating cooling water system annual average cooling energy efficiency ratio energy consumption comprehensive evaluation index and method, belonging to the field of industrial energy conservation and emission reduction. Background technique [0002] Industrial circulating cooling water systems are mainly distributed in petrochemical, metallurgy, thermal power and other high-energy state monopoly industries. The circulating cooling water system is generally composed of heat exchange equipment, circulating water pumps, water pipelines and heat dissipation equipment, and consumes a lot of energy during the operation of the system. The traditional evaluation method that uses the efficiency of the circulating water pump as the energy consumption evaluation index of the circulating cooling water system has the following problems: First, th...
