Description

Technical Field

[0001] The utility model relates to the technical field of dry fog dust suppression, in particular to a spray box used for dry fog dust suppression. Background Art

[0002] Dry fog dust suppression is an advanced dust control technology that disperses water molecules into very small particles by spraying fine dry mist. These particles are much smaller than traditional water mist. When these tiny water particles come into contact with dust particles in the air, they will adsorb and deposit on the surface of the dust, increase the weight of the dust particles, and make them settle to the ground. Dry fog dust suppression is widely used in mining, construction, ports, road construction and other industries to improve the cleanliness and safety of the working environment. The spray terminal of the dry fog dust removal device is a spray box. Water and air are mixed in the spray box and sprayed out in the form of mist.

[0003] The existing spray box has a fixed size and cannot be adjusted. When installing (such as installing on one side of a material turning robot arm), the size of the spray box needs to be customized according to the size of the required installation location, and its use cost is relatively high.

[0004] Therefore, we propose a spray box for dry fog dust suppression in order to solve the above problems. Utility Model Content
