Problems solved by technology

[0003] At present, the calculation of the cooling efficiency of the cooling tower is based on the field test. After screening the reasonable time period data, it is calculated according to the relevant formula. The result can only reflect the operation status of the cooling tower at the time of the test. The timeliness is poor, the labor cost is high, and it cannot be used for a long time. Monitor cooling tower health

Embodiment Construction

[0056] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0057]A cooling tower is a device that uses water as a circulating coolant to discharge waste heat from industrial production or refrigeration processes into the atmosphere. Its principle is to use water and air to exchange heat and cold to generate steam, and the steam evaporates to take away heat to achieve cooling. Cooling towers are divided into: natural ventilation cooling towers, mechanical ventilation cooling towers and mixed ventilation cooling towers according to ventilation methods; cooling towers are divided into wet cooling towers, dry cooling towers and wet and dry cooling towers according to the contact mode of hot water and air Tower; Cooling towers are divided into counter-flow cooling towers, cross-f...

Abstract

The invention belongs to the field of tests, and particularly relates to a method and a system for monitoring the cooling efficiency of a cooling tower. The method comprises the following steps of: obtaining real-time parameters and design parameters of the cooling tower; calculating actually measured flow of air entering the tower, an actually measured gas-water ratio and a corrected cooling number according to the real-time parameters and the design parameters; determining a corrected gas-water ratio according to the actually measured gas-water ratio, the corrected cooling number and a design curve in the design parameters; and monitoring the cooling efficiency of the cooling tower according to the calculating actually measured flow of air entering the tower, the corrected gas-water ratio and designed flow of water entering the tower in the design parameters. The method realizes monitoring the cooling efficiency of the cooling tower in real time, is high in real-time property, is lower in cost, and is higher in energy consumption ratio, and enables the cooling tower to be in the optimal operation state.

Description

technical field [0001] The invention belongs to the field of testing, in particular to a method and system for monitoring the cooling efficiency of a cooling tower. Background technique [0002] With the increasing requirements of urban construction and planning, cooling towers are used more and more in industrial sectors such as electric power and chemical industry. As one of the important auxiliary equipment in industries such as power plants and chemical plants, the operating status of cooling towers directly affects The safe and economical operation of the main engine, at the same time, the cooling tower is also one of the auxiliary equipment that consumes a lot of power in the factory. With the improvement of environmental protection indicators and energy-saving consumption requirements, the economic operation of cooling towers will become more and more important. [0003] At present, the calculation of the cooling efficiency of the cooling tower is based on the field ...
