Description
Technical Field
The invention relates to the technical field of dust fall of construction sites, in particular to an automatic adjustment spraying dust fall system based on wind field parameters.
Background
The influence of dust pollution on the air quality of cities and surrounding environments is more and more serious at present, and pollution phenomena such as haze and the like cause the air quality of the current cities to be increasingly deteriorated. The serious air dust pollution problem has caused serious influence on the health of people, and the outbreak of respiratory diseases such as urban population asthma and the like is increased, so that the air dust pollution is reduced, and the method is an important environment-friendly measure for improving the urban air quality.
With the rapid development of national economy, the urban construction process of China is increasingly accelerated. The dense development of urban construction, municipal engineering and other engineering projects causes the outstanding dust pollution problem in urban and peripheral engineering field areas, and leads to the high urban air dust pollution index. As one of the main sources of urban air dust pollution, how to reduce and block dust in exposed engineering sites from entering urban air is a key for improving urban air quality.
In order to reduce building site raise dust, at present mainly adopt simple screen panel or enclose and keep off isolation method at the building site, some serious building sites of raise dust increase simple and easy water spray nozzle at most on enclosing and keep off to carry out the inefficiency and suppress the dirt, the specific practice is: the simple spraying device is installed on the fence of the construction site, and water drops sprayed by the spraying device moisten dust in the air at the close distance of the fence, so that the specific gravity of dust particles is increased and falls down under the action of gravity. The method has low spraying height, small radius and low dust settling efficiency, and wet dust is easy to lose water again in the air and raise, so that the dust settling effect is very low especially in dry areas and autumn and winter drying seasons, and limited dust settling can be achieved by repeated infiltration.
At present, the construction site enclosure spraying dust fall system mainly adopts the following steps: the device described in the publication No. CN106731345 has low dust settling effect, each section of the enclosing shield needs an independent spraying system, and the cost is high. Because the particle size of the water drops is large, more ineffective water drops without infiltrating dust in the air can be caused, the surface tension of the water drops is large, most dust passing through a spraying area cannot be wetted in a short time, a large amount of water resources are wasted, and the problem of low dust falling effect is solved, so that the dust can cross over a surrounding barrier to enter the surrounding air. When the construction site dust falling method and device are adopted, the height requirement that dust passes over the enclosure is ensured by increasing the height of the enclosure. But when the height of the enclosure is increased, the supporting structure and the strength of the enclosure are also increased, so that the enclosure structure is more complex, and the construction cost of the enclosure is greatly increased. Meanwhile, due to the increase of the height of the high enclosure, the wind resistance area of the enclosure is increased, the wind-induced instability damage is easy to occur, the integral overturning collapse damage is easy to occur in strong wind climate or strong wind area, and the potential safety hazard can lead to irreversible casualties and economic losses. When the construction site dust fall method and device disclosed in the above patent are used, due to the fact that the water consumption is large, invalid water drops accumulate, secondary sewage discharge pollution is easily generated after surrounding soil and non-raised dust are soaked, surrounding mud is caused, the environment is influenced, meanwhile, the dust pollution problem is expanded to a farther range by muddy water, meanwhile, sewage with silt flows into urban sewer, and secondary pollution problems such as blockage of the sewer around an engineering site are caused. When the construction site dust falling method and device disclosed in the patent are used, the spraying direction and range cannot be adjusted, only a single spraying mode can be realized, and effective adjustment cannot be performed according to the actual engineering condition and the on-site air flow state, so that waste of resources and ineffective work are caused.

2. By adopting the three-dimensional spraying technology, the spraying height can be adjusted within the range of 0.5-1.5m by controlling parameters such as water pressure, charge quantity, flow and the like in the system, and the spraying radius can meet the requirement of full coverage at the boundary of a construction site. The adjustable spraying height can solve the problem that different environment conditions of different construction sites in different construction stages need different spraying height to prevent dust from flowing out of the construction site when dust concentration is different in the vertical direction of the construction site enclosure boundary, thereby realizing accurate dust fall and improving dust fall rate. And moreover, the dust fall range is enlarged in the height direction, the actual enclosure height is effectively reduced, the wind resistance area of the enclosure is further reduced, the wind-induced effect of the enclosure is reduced, the wind-induced stability of the enclosure with a large area is ensured, the wind-induced safety of the enclosure is improved, and the strong wind overturning accident of the enclosure is effectively prevented.
3. As shown in fig. 11, the hierarchical dust fall can be realized, and according to the wind direction and wind speed fed back by the distributed sensing detection subsystem, the dust distribution caused by the excavation or the soil piling of the construction site and other field reality, the controller is used for automatic control, or the spray functions of different modes and combinations are manually adjusted to carry out the hierarchical dust fall, so that the effective saving of energy sources is realized, the dust fall purpose is improved, and the efficient dust fall control is carried out.
4. Can be recycled, is easy to disassemble, assemble, reorganize and expand, can meet the requirement of quick turnover use of engineering equipment, and avoids waste of disposable equipment.
5. In island engineering and coastal engineering, the seawater filtered by the primary impurities or other secondary water can be directly used as a spraying medium, thereby saving limited precious fresh water or municipal water resources, saving energy and protecting environment.
6. The adopted electrostatic mist technology ensures that the electrostatically charged mist drops are not easy to lose water and dry after being adsorbed on dust, thereby avoiding the problem of secondary dust emission after water loss, realizing the purpose of primary dust fall and having good adaptability in dry areas and autumn and winter drying seasons.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
