Cooling tower filler performance experiment detection system

Abstract

The invention discloses a cooling tower filler performance experiment detection system, and belongs to the technical field of filler performance detection. The system comprises an air mixing area andan air exhaust area which are arranged on the outer side of a filler performance detection laboratory, a variable frequency fan a is arranged between the filler performance detection laboratory and the air exhaust area, an electric shutter a is arranged between the filler performance detection laboratory and the air mixing area, and an electric shutter b is arranged between the air mixing area andthe air exhaust area; the air exhaust area is provided with two symmetrical air exhaust outlets, and variable frequency fans b are arranged at the air exhaust outlets. The system has the beneficial effects that the environment wet bulb temperature in the test is accurately controlled, the test precision is high, and the filler test error, time and material resources can be greatly reduced; due tothe fact that the system adopts hot air backflow recycling, filler testing can be conducted in winter, and the time range of filler testing is widened. And the whole system adopts full-automatic control and acquisition, so that the manpower can be greatly saved, and the test precision is guaranteed.

Description

technical field [0001] The invention relates to a cooling tower packing performance experimental detection system, which belongs to the technical field of packing performance detection. Background technique [0002] Today, with the rapid economic development, energy consumption is increasing day by day. How to use energy efficiently and reduce energy waste has become a difficult problem to be solved. As a device for heat exchange and heat dissipation, cooling towers are more and more widely used with the deepening of the process of big data. Cooling tower fill is the main part of cooling tower heat and mass transfer exchange, and its heat dissipation capacity directly affects the overall operation effect of cooling tower. At present, the parameters to measure the performance of the packing are the cooling number, the bulk mass coefficient and the packing resistance, etc. The heat transfer capacity of the packing is related to the temperature and humidity. The existing techn...

Problems solved by technology

At present, the parameters to measure the performance of the packing are the cooling number, the bulk mass coefficient and the packing resistance, etc. The heat transfer capacity of the packing is related to the temperature and humidity. In the prior art, the performance of the packing is evaluated by testing the performance of the cooling tower (such as the publication number: CN206920370U, patent name: a cooling tower packing detection test device for eliminating wall flow loss, and publication number: CN107328809A, patent name: cooling tower packing detection test device and packing detection method for eliminating wall flow loss), a great waste of manpower , material resources; due to the fluctuation of external temperature and humidity, the test results fluctuate greatly, and the performance of the filler cannot be accurately evaluated, and the error is large; the wet bulb temperature of the external environment in winter is lower than 10°C, and the performance of the filler cannot be evaluated
