Background
With the increasing interest of China on air quality, the construction industry focuses more on the treatment method of the dust, and at present, the common existing technologies in the industry are as follows: in dry seasons, a large amount of dust can be generated in a construction process of a building construction area, air is polluted, and certain damage is caused to the bodies of field workers; along with the rapid development of urban construction, the construction engineering quantity of old buildings is larger and larger, but a large amount of smoke dust is often caused in the construction engineering, and the air environment in the city is greatly influenced. In the construction projects of old buildings, because the coordinated working schedules of residents of old buildings are inconsistent, in order to not delay the construction period of the construction projects, a mode of 'talking while dismantling' is often adopted: and preferentially building the houses of the coordinated residents which are removed, and then gradually building the houses of the subsequent coordinated residents. However, a large amount of dust generated in such construction works greatly affects the life of residents who have not been removed, and is not favorable for ensuring the health of residents who have not been removed.
At present, the main modes for reducing the raised dust on the construction site include a covered dust screen, a sprinkler for sprinkling water and a fog gun; the existing sprinkling truck is adopted to sprinkle water to reduce dust raising, only a soil layer on the surface is soaked, and a large amount of dust raising is generated in the process of excavating earthwork; the existing fog gun and dust screen are adopted to reduce the dust emission, and the effect is poor in the windy weather state. In summary, the problems of the prior art are as follows: the dust is reduced in the current watering of adoption watering lorry, only soaks the soil layer on surface, still can produce a large amount of dust at the excavation earthwork in-process. The existing fog gun and dust screen are adopted to reduce the dust emission, and the effect is poor in the windy weather state.

and 4, step 4: processing the pollution diffusion simulation file, and analyzing to obtain pollution indexes of different dust emission areas as prediction results;
and 5: and monitoring the prediction results of different dust emission areas, giving an alarm when the prediction results exceed a set index range, and accurately positioning the pollution source by combining the positioning information of the corresponding areas.
Step 6, when the dust concentration exceeds the preset range of the control system, the control system controls the spraying method to carry out spraying dust removal;
and 7: a PVC water pipe is laid in the building, a water pump is installed outside the house building, and the water pump is respectively communicated with the PVC water pipe and the sprinkler;
and 8: storing water and soaking, and starting a water pump to convey water in the sprinkler into the building and soak for a certain time;
and step 9: sprinkling water to the exterior of the building;
and step 10, monitoring the dust concentration in real time by the dust sensor, and controlling the spraying method to stop spraying and dedusting by the control system when the dust concentration reaches the standard of the control system.
Step 7, after the water pump is started, observing for at least 10 minutes, gradually adjusting the spraying amount according to the observation condition until the wall surface is wet and water is not accumulated on the ground, opening each spraying head and adjusting the water amount, wherein the water amount is continuously sprayed;
and 9, arranging at least 2 spray heads on one wall for water spraying.
In the step 9, the vinyl acetate polymerization derivative is added into the water during sprinkling to improve the dust inhibition effect.
The external sprinkling is specifically that the sprinkler is used for regularly sprinkling towards the outside of the building.
The invention has the beneficial effects that:
by sprinkling water outside the building, the wall, the roof and the ground in the building are wetted, and then sprinkling water outside the building, powder on the inner wall and the outer wall of the building are fully contacted with the water, so that the powder is attached to the water, a large amount of dust is prevented from flying in the building process of the building, the diffusion of the flying dust to surrounding buildings is reduced, the influence of building engineering on the life of residents who are not moved away is prevented, and the health of the residents who are not moved away is favorably ensured; under windy weather condition, according to can keeping good effect, can protect the hard tube through the steel billet can not warp to can aim at the regional limit of construction excavation and spout water, can drive the hard tube of water spray through rotating electrical machines and rotate the water spray, improve the dust removal area. The method for removing the raise dust in the building construction area can be intelligently controlled through the control system, and manual operation is omitted.
