the temperature is kept at 20 ℃, the relative humidity of the environment is 40%, and the atmospheric pressure is 101kpa, a plurality of groups of experiments are carried out, and the experimental data of primary pollution, secondary pollution and tertiary pollution are respectively shown in table 1, table 2 and table 3.
TABLE 1 relationship of spray time with TSP concentration under first-class contamination
| TSP concentration (mg/m)3) | 0.8 | 0.9 | 1.0 | 1.1 | 1.2 | 1.3 | 1.4 |
| Reduced to 0.6mg/cm3Required time(s) | 23.13 | 50.08 | 73.15 | 93.11 | 110.09 | 124.30 | 136.25 |
| ΔT/ΔC | 269.5 | 230.7 | 199.6 | 169.8 | 142.1 | 119.5 | 105.1 |
Multiple experiments are carried out to obtain multiple groups of data, when the pollution is the first class, a fitting curve is shown in figure 3, and the fitting curve shows that the total delta T/delta C is 0.2CX 1000 (the measured TSP concentration is C), namely, the spraying time needs to be increased by 0.2 when the TSP concentration is increased by 0.1CX 100s, then:
T1＝(C-0.8)×0.2C×100+23。
TABLE 2 relationship of spray time with TSP concentration under secondary pollution
| TSP concentration (mg/m)3) | 1.5 | 1.6 | 1.7 | 1.8 | 1.9 |
| Reduced to 0.6mg/cm3Required time(s) | 146.76 | 152.65 | 156.63 | 160.61 | 163.33 |
| ΔT/ΔC | 58.9 | 48.1 | 39.8 | 32.9 | 27.2 |
| TSP concentration (mg/m)3) | 2.0 | 2.1 | 2.2 | 2.3 | 2.4 |
| Reduced to 0.6mg/cm3Required time(s) | 165.58 | 167.44 | 169.30 | 170.84 | 172.11 |
| ΔT/ΔC | 22.5 | 18.6 | 15.4 | 12.7 | 10.5 |
In the case of secondary contamination, the fitted curve is shown in FIG. 4, and it was found from the fitted curve that Δ T/Δ C was always 0.15CX 1000 (the measured TSP concentration is C), namely, the spraying time needs to be increased by 0.15 when the TSP concentration is increased by 0.1CX 100s, then:
T2＝(C-0.8)×0.15C×100+136。
TABLE 3 relationship of spray time with TSP concentration under three-level pollution
| TSP concentration (mg/m)3) | 2.5 | 2.6 | 2.7 | 2.8 | 2.9 |
| Spraying to 0.6mg/cm3Required time(s) | 173.16 | 173.66 | 174.06 | 174.39 | 174.59 |
| ΔT/ΔC | 5.0 | 4.0 | 3.3 | 2.6 | 2.1 |
| TSP concentration (mg/m)3) | 3.0 | 3.1 | 3.2 | 3.3 | 3.4 |
| Spraying to 0.6mg/cm3Required time(s) | 174.86 | 175.03 | 175.17 | 175.28 | 175.3 |
| ΔT/ΔC | 1.7 | 1.4 | 1.1 | 0.91 | 0.74 |
The fitted curve is shown in fig. 5 for tertiary contamination, and it was found from the fitted curve that Δ T/Δ C was always 0.12CX 1000 (the measured TSP concentration is C), namely, the spraying time needs to be increased by 0.12 when the TSP concentration is increased by 0.1CX 100s, then:
T3＝(C-0.8)×0.12C×100+173。
from the fitted curve shown in fig. 5, it can be seen that when the TSP concentration is greater than 2.4mg/m3, the sprinkling time varies only within a small range, all approaching 175 s.
The influence of temperature and humidity on the spraying efficiency is analyzed through experiments.
Experiments show that the spray head sprays fan-shaped mist spray for 10s, the sprayed liquid a ml/s has exponentially multiplied length with the evaporation time under the ambient air pressure of 101kpa, the temperature is X (centigrade) when evaporation is carried out, the evaporation time(s) is Y, and the experimental data comprise: -1.06X +360 (evaporation time 360s at 0 degrees celsius), average evaporation rate 10a/Y ml/s, and evaporation capacity at temperature Q ═ T × 10/a (-1.06X +360), assuming T seconds of injection, equal to the amount of liquid injected T ═ T × 10/(-1.06X + 360);
experiments show that the relationship between the time required for reducing the TSP concentration from 1.8 to 0.8 and the relative humidity at the temperature of 20 ℃ under the ambient pressure of 101kpa is close to a linear function relationship with the spraying time. For every 5% increase in relative humidity, the spraying time is reduced by 3s on average, i.e. 3a ml of sprayed spray liquid is reduced, i.e. for every 1% increase in humidity, the volume of spray liquid can be reduced by 0.6a ml, which is equal to the spray volume with a spray t of 0.6 s.
The calculation formula of the spraying time is determined through the experimental analysis:
the dust concentration, the temperature and the humidity of the construction section detected by the dust concentration sensor and the temperature and humidity sensor are C, X and n respectively;
when the concentration is 0.8mg/m3≤C≤1.4mg/m3When the pollution is generated, namely the first-level pollution is generated,
when the concentration is 1.4mg/m3≤C≤2.4mg/m3When the pollution is generated, namely the secondary pollution is generated,
when C is more than 2.4mg/m3When the pollution is not available, namely the pollution of the third level exists,
because the laboratory calculation result is obtained by reducing the ratio of the actual engineering condition and the like, and the laboratory is not consistent with the actual engineering condition, when the space is increased, the diffusion speed and the range of molecules are increased, and the required spraying processing time is longer than the laboratory calculation time. Through a plurality of groups of comparison tests, the construction spraying time is as follows:
t1＝T1×α1(α1＝1.6)；t2＝T2×α2(α2＝1.4)；t3＝T3×α3(α3＝1.3)。
the dust fall process is the process that water smoke and raise dust granule combine to subside, and when spray set started, water smoke concentration in the air was sharply increased, and water smoke and raise dust granule bonding rate are lower, so under the unchangeable prerequisite of total amount of spraying, the extension sprays the time, can effectively increase dust fall efficiency, and 6s are given as a circulation of spraying in the formula, calculate respectively and spray time and spray the interval time.
The reasonable time of each spraying is obtained by combining the conditions:
when the concentration is 0.8mg/m3≤C≤1.4mg/m3When the water is polluted at first level, the main control module presses down to calculate the spraying time t1And interval time t1′：
t1′＝6-t1；
When the concentration is 1.4mg/m3≤C≤2.4mg/m3When the secondary pollution is caused, the main control module presses down to calculate the spraying time t2And interval time t2′：
t2′＝6-t2；
When C is more than 2.4mg/m3When in time, namely three-level pollution, the main control module presses down two modes to calculate the spraying time t3And interval time t3′：
t3′＝6-t3；
