With respect to a test meter employed for a test device, comprising:
a) Atmospheric weather parameter detection part:

C) Ventilation amount and wind speed detection part:
The test instrument is an L-shaped standard type Pitot tube and a micropressure meter.

Each measuring point is provided with a corresponding filter paper, each filter paper is arranged between the adjacent high-level water receiving devices, and before the water-absorbing filter paper is tested, a tester carries out drying treatment on the filter paper, so that the water-absorbing effect of the filter paper is ensured. The filter paper is not damaged before and after the test, and the quality change can reflect the splash quantity. After the test, the filter papers are collected and summarized uniformly, so that the filter papers are prevented from being lost and the moisture is prevented from evaporating, and the test precision is ensured.
In the embodiment of the invention, a filter paper wet absorption method is adopted to carry out a splash performance test of the cooling tower, namely, a filter paper weighing method is adopted to determine the splash amount and the splash rate. The filter paper weighing method is to firstly put the filter paper into a sealed plastic bag to weigh, take out the filter paper and put the filter paper at a certain measuring point to collect splashed water drops in the test, and put the filter paper into the plastic bag to weigh again after the collection time is t minutes, wherein the weight difference is the amount of splashed water collected at a certain position in the time.
In a preferred embodiment, for each first water receiving inclined plate, the first water receiving inclined plate is divided into a plurality of sampling points, the splashing amount of one sampling point is calculated first, and the obtained splashing amounts of all sampling points are calculated, so that the splashing amount of one sampling point of the first water receiving inclined plate is calculated, specifically:
calculating and obtaining the splashing amount of a sampling point of the first water receiving inclined plate according to a second formula; wherein the second formula is as follows:
wherein S i is the splash amount of a sampling point, M 1 is the weight of the filter paper before collecting the water drops, M 2 is the weight of the filter paper after collecting the water drops, t is the sampling time, and A is the area of the filter paper.
After the splash amount of each sampling point is obtained, calculating according to a first formula to obtain a first average splash amount of the first water receiving inclined plate; wherein, the first formula is:
Wherein, And N is the total number of sampling points, and S i is the splashing amount of one sampling point.
According to the embodiment of the invention, the data obtained when the splashing amount of the water receiving inclined plate of the high-level water receiving mechanical ventilation cooling tower is detected can be more accurate through the detection device, and the more accurate splashing amount can be obtained through a corresponding calculation method.
For step S2, in a preferred embodiment, the calculating the first water splashing rate of each first water collecting inclined plate according to the average water splashing amount of each first water collecting inclined plate, taking a first water collecting inclined plate with the smallest first water splashing rate as a target water collecting inclined plate, taking the material of the target water collecting inclined plate as a target material, and taking the shape of the target water collecting inclined plate as a target shape specifically includes:
In this example, the amount of splash was defined as the difference in weight of the water absorbing filter papers before and after the test; the splash rate is defined as the ratio of the total splash water per unit time to the effective circulating water. The difference between the splashing amount and the splashing rate is: the splash rate is dimensionless, and the core is the ratio of splash water to shower water;
calculating a first splashing rate of each first water receiving sloping plate according to the average splashing amount of each first water receiving sloping plate, wherein the first splashing rate specifically comprises:
calculating a first splash rate of each first water receiving inclined plate according to the following formula:
wherein e is the first splash rate, A 1 is the average splashing amount of the first water collecting inclined plate, A 1 is the splashing area of the first water collecting inclined plate, and q is the circulating water amount of the mechanical ventilation cooling tower.
By calculating the first splashing rate of each first water receiving sloping plate, the splashing rates of a plurality of water receiving sloping plates with different structures and different materials can be obtained, in a preferred embodiment, the first water receiving sloping plates at least comprise an original water receiving sloping plate and an improved water receiving sloping plate, then as shown in fig. 3-4, fig. 3 is a splashing rate change rule corresponding to the original water receiving sloping plate and changing along with the water spraying density under the same splashing prevention filler coverage area, and fig. 4 is a splashing rate change rule corresponding to the improved water receiving sloping plate and changing along with the water spraying density under the same splashing prevention filler coverage area;
From the test results of fig. 3 and 4, it can be seen that when the water spraying density is increased from 13.25m 3/(m 2, h) to 17.5m 3/(m 2, h), the water spraying rate of the original water collecting inclined plate assembly is increased from 0.0000462 to 0.0000719, 55.6% is increased, and the water spraying rate of the improved water collecting inclined plate assembly is increased from 0.00001 to 0.000013, and 30% is increased. With the increase of the water spraying density, the water splashing rate is gradually increased, but under the same water spraying density, the water splashing rate of the improved water collecting inclined plate is obviously smaller than that of the original water collecting inclined plate, the improved water collecting inclined plate can be selected as a target water collecting inclined plate, the material of the improved water collecting inclined plate is used as a target material, and the shape of the improved water collecting inclined plate is used as a target shape;
For step S3, in a preferred embodiment, a plurality of second average splashing amounts of the plurality of second water collecting inclined plates corresponding to the same water spraying density are obtained, and a corresponding second splashing rate is calculated according to the second average splashing amount of each second water collecting inclined plate; specifically, the calculating process and method of the second splash rate are consistent with the calculating process and method of the first splash rate, and are not described herein again;
The material of each second water collecting inclined plate is a target material, the shape of each second water collecting inclined plate is a target shape, and the splash-proof filler coverage area of each second water collecting inclined plate is different; that is, the material of each second water-collecting inclined plate can be the material of the improved water-collecting inclined plate, and the shape of each second water-collecting inclined plate can be the shape of the improved water-collecting inclined plate, so that the splash patterns of the second water-collecting inclined plate corresponding to different coverage areas can be obtained under the same water-spraying density, and the splash patterns of the second water-collecting inclined plate corresponding to different coverage areas are shown in fig. 5;
From the test results of fig. 5, the splashing rate of the improved water receiving sloping plate is obviously lower than that of the original water receiving sloping plate, and when the improved water receiving sloping plate is adopted, the splashing rate gradually decreases along with the increase of the coverage area of the splashing-preventing filler; however, when the splash packing area is larger than 1/2, the splash rate is less changed. The splash rate of the improved water recovery swash plate-1/2 coverage (at which the splash rate is 0.00001) is reduced by about 78.4% compared to the original water recovery swash plate-1/2 coverage (at which the splash rate is 0.0000462). And compared with the original water receiving inclined plate-1/2 cover (at the moment, the splashing rate is 0.0000462), the splashing rate of the improved water receiving inclined plate-full cover (at the moment, the splashing rate is 0.000007) is reduced by about 84.8%; therefore, the improved water collecting inclined plate can further explain that when the area of the splash-proof packing is larger than 1/2, the splash rate is less changed;
for step S4, in a preferred embodiment, each second water receiving sloping plate with the second water splashing rate not greater than the preset water splashing rate is used as each second target water receiving plate, and the target range of the coverage area of the splash-proof filler is determined according to the coverage area of the splash-proof filler of each second target water receiving plate, which specifically includes:
From the test results of fig. 5, it can be seen that, when the water spray density is the same, that is, when the water spray density is 13.25m 3/(m 2. H), the improved water collecting inclined plate with 1/2 coverage area, the improved water collecting inclined plate with 2/3 coverage area and the improved water collecting inclined plate with full coverage area have the water spray rate of the three water collecting inclined plate assemblies not greater than the preset water spray rate; in a preferred embodiment, the predetermined splash rate is 0.00001.
And according to the second water receiving inclined plates (the improved water receiving inclined plate with the second water splashing rate not larger than the preset water splashing rate, the improved water receiving inclined plate with the 2/3 coverage area and the improved water receiving inclined plate with the full coverage area) serving as the second target water receiving plates, and according to the splash-proof filler coverage areas of the second target water receiving plates, obtaining a target splash-proof filler coverage area range, namely, the target splash-proof filler coverage area range can be from 1/2 coverage area to full coverage area.
For step S5, in a preferred embodiment, the water receiving sloping plate having the same shape and the same material as the target material and having the splash-proof filler coverage area within the range of the target splash-proof filler coverage area is used as the water receiving sloping plate meeting the splash-proof standard, that is, the water receiving sloping plate having the splash-proof filler coverage area within the range of the target splash-proof filler coverage area (1/2 coverage area-full coverage area) is used as the water receiving sloping plate meeting the splash-proof standard according to the target shape (may be the shape corresponding to the improved water receiving sloping plate), the target material (may be the material corresponding to the improved water receiving sloping plate) determined in the above step, and the plurality of water receiving sloping plates meeting the splash-proof standard are arranged under the mechanical ventilation cooling tower, so that the splash-proof rate can be reduced, and the splash-proof requirement of the mechanical ventilation cooling tower can be met.
