Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment:

[0030] In conjunction with the accompanying drawings, the present invention will be further described in detail by taking the energy-saving technical transformation of the SP system of the 19# water station of a steel plant water supply plant.

[0031] The SP system is a soft water closed system. In this system, the return water used by the user is cooled by the plate heat exchanger, and then enters the water pump inlet for recirculation.

[0032] This system is used for cooling stave and furnace bottom of 4# blast furnace, including 3 water pumps, 2 for normal use and 1 for standby. The design flow rate of each system is 5200m 3 / h. The system is equipped with 3 water pumps.

[0033] 1. Obtain relevant parameters and measure the pipe network resistance loss of the existing water system;

[0034] (1) The nameplate parameters of the pump...

Abstract

The invention discloses an energy-saving method for a stable flow water system, which is characterized by comprising the following steps: firstly, measuring the pipe network resistance loss of the conventional water system; secondly, rectifying and reforming the water system pipe network of the conventional system; thirdly, measuring the water pump lift of the rectified water system; and fourthly, obtaining the optimal water pump suitable for the water system according to characteristics of the water system pipe network, hydrodynamic equations and a water pump working efficiency curve. According to the invention, the energy-saving method for the water system can be easily realized, the power consumption of the water system can be greatly saved through the adoption of the method, the energy-saving effect is remarkable, the selected new water pump can meet the requirement of the current water system, further reserves the follow-up expansion space, so that the design and manufacture cost of the water system is reduced.

Description

technical field [0001] The invention belongs to water delivery or circulation systems in the fields of cooling, circulation, water supply and the like, and relates to an energy-saving method for a stable flow water system. Background technique [0002] Water delivery or circulation systems are widely used in cooling, circulation, water supply and other fields, and their power consumption is huge, reaching 20% ​​of the world's electricity consumption. In the water delivery or circulation system, there are a large number of unreasonable matching problems between the water pump and the system pipe network, resulting in a huge waste of energy. [0003] The energy consumption of the water system is mainly generated by the water pump. In actual engineering, the conventional design of the water system and the selection of water pumps are often designed and matched according to the most unfavorable working conditions, and in order to pursue safety one-sidedly, generally there is a ...
