In the environment-friendly dust-settling device for highway engineering construction according to this embodiment, in some embodiments, as shown in fig. 1 and fig. 2, casters 12 are installed at four corner positions of the bottom of the liquid storage tank 1. The present embodiment facilitates the movement of the position of the dust settling device by providing casters 12.
In some embodiments, as shown in fig. 1 and fig. 2, a handle 13 is further installed at one end of the liquid storage tank 1. The present embodiment is provided with the handle 13 so that the user pushes the dust settling device through the handle 13.
The environment-friendly dust fall device for highway engineering construction comprises a liquid storage tank 1 and an air box 2, wherein the liquid storage tank 1 is provided with a first liquid storage cavity for storing a first foaming agent, a second liquid storage cavity for storing a second foaming agent and a third liquid storage cavity for storing spray water; specifically, the first foaming agent can be in a liquid state with good fluidity without bubbles under the stirring of compressed air; the second bubble agent can generate uniform and continuous foam under the stirring of compressed air; the top of the liquid storage tank 1 is provided with a liquid tank cover 11, and the air box 2 is arranged on the liquid tank cover 11;
the outer wall of the bellows 2 is provided with a first liquid spraying component 3 for generating bubbles, a second liquid spraying component 4 for conveying foam units and a third liquid spraying component 5 for conveying water mist; the first liquid spraying component 3, the second liquid spraying component 4 and the third liquid spraying component 5 are respectively connected with the first liquid storage cavity, the second liquid storage cavity and the third liquid storage cavity.
Specifically, the first liquid spraying component 3 generates bubbles with larger volume from the first foaming agent under the action of air flow generated by the air box 2, and the second liquid spraying component 4 generates continuous foam from the second foaming agent under the action of air flow generated by the air box 2; the third spray assembly 5 causes spray water to produce mist under the action of the air flow generated by the air box 2.
When large-area dust emission occurs on an engineering construction site and dust fall treatment is required to be carried out rapidly, the air box 2 continuously generates high-speed air flow, then water mist is generated under the action of the air flow generated by the air box 2 through the third liquid spraying component 5 to form primary atomization of spray water, the generated water mist is guided to the air outlet end of the air box 2 through the third liquid spraying component 5, so that the water mist is atomized secondarily under the impact of the high-speed air flow, and the water mist after the secondary atomization is sprayed into the air in a dispersed manner under the carrying of the high-speed air flow discharged by the air box 2, so as to trap and subside dust emission particles in the air;
when more particles exist on the ground of an engineering construction site and lower dust suspended near the ground appears, if dust fall is carried out in a mode of spraying water mist, on one hand, the water mist particles are smaller, the spraying range is difficult to control, the water mist with higher spraying height is likely to drift out of a construction area along with wind, adverse effects are likely to be caused on the external environment, and on the other hand, in order to fully cover the dust range, the spraying quantity of the water mist is required to be increased, so that the waste of spraying water is caused; at the moment, continuous foam is generated under the action of air flow generated by the air box 2 through the second liquid spraying component 4, the generated continuous foam is guided to the air outlet end of the air box 2, the continuous foam is dispersed into small foam units under the impact of high-speed air flow, and the foam units are dispersed in a dust raising area under the driving of the air flow to collect and settle dust raising particles in the air in the dust raising area; compared with water mist, the foam unit has larger mass and larger surface area, has larger sedimentation speed, can ensure the trapping effect on dust particles, is easier to control the spraying range, ensures more accurate spraying and saves water;
when the engineering construction site is in a relatively closed space and the dust falling speed requirement is relatively low, bubbles with larger volume are generated under the action of air flow generated by the air box 2 through the first liquid spraying component 3, the bubbles fly in the dust raising space along with the air flow, the bubbles are broken after adsorbing dust raising particles and are converted into liquid drops, and the trapped dust raising particles fall to the ground, and as the surface area of the bubbles generated by the first air spraying agent in unit volume is far larger than the surface of water mist generated by spraying water in unit volume, the dust trapping efficiency is higher, and the water consumption is less;
according to the embodiment, the first spraying component, the second spraying component and the third spraying component are arranged on the bellows 2, and the first spraying component, the second spraying component and the third spraying component are respectively connected with the first liquid storage cavity storing the first foaming agent, the second liquid storage cavity storing the second foaming agent and the third liquid storage cavity storing spraying water, so that dust can be trapped and reduced according to actual dust-reducing working conditions, and the dust-reducing effect can be effectively improved, and the dust-reducing water consumption can be reduced.
