Embodiment
[0045] Firstly, test the air parameters of the inlet tower, the air parameters above the water eliminator and the air parameters above the hot channel of the mist removal module. Calculate the air parameters of each part to calculate the weighted average moisture content of the air, where the mass flow weighted average moisture content of the air above the water eliminator is d 1m , the mass flow weighted average moisture content of the air above the hot aisle of the defogging module is d 2m , the average moisture content of the air entering the tower is d 3m . In this embodiment, the water-saving rate η ws =(d 1m -d 2m ) / (d 1m -d 3m )=(0.02965-0.02399) / (0.02965-0.00405)×100%=22.1%. .

The invention discloses a method for calculating the water saving rate of a condensation type fog-dispersing water-saving cooling tower. The method comprises the following three steps: firstly, testing parameters of air entering the tower, parameters of air above a dehydrator and parameters of air above a heat channel of a fog dispersal module, and calculating the moisture content of the air through the air parameters; calculating the average moisture content of each test point through the air moisture content; and calculating the water saving rate of the cooling tower through the average moisture content. According to the method, the water-saving effect of the condensation type fog-dispersing water-saving cooling tower is investigated through the moisture content change of the air, and clear meaning and feasible process are realized; the water saving rate of the condensation type fog-dispersing water-saving cooling tower can be calculated under different working conditions, the understanding of a water saving rate test is improved, and the water-saving effect of the condensation type fog-dispersing water-saving cooling tower can be directly evaluated on site; and the method essentially relies on a ratio of a recycled water quantity to an evaporated water quantity.
Description
technical field [0001] The invention belongs to the technical field of cooling towers, and in particular relates to a method for calculating the water-saving rate of a condensation-type fog-elimination and water-saving cooling tower. Background technique [0002] With the continuous enhancement of people's awareness of environmental protection and water conservation, condensing fog-elimination and water-saving cooling towers have been continuously used in my country in recent years, but the performance of technical products of different manufacturers is uneven, and my country has not formulated regulations on condensing Relevant standards for test methods of water saving rate of fog water-saving cooling towers. The traditional method of direct measurement of water saving through a specially set water receiving device and flow measuring device requires special design during the installation stage of the cooling tower, which increases the installation cost and is technically di...
