Abstract
A spraying system for controlling air-borne particulate matter, such as coal dust, has a housing including a diverging diffuser portion into which a spray of liquid is injected. The spray causes a flow of air to pass into the diffuser portion and mix with the liquid to form a mist which passes from the diffuser portion to form a diverging jet downstream of the outlet of the diffuser portion. This diverging jet causes air molecules to be drawn into the mist and removed from the air through which the mist is passing.
Claims5
A spraying system for controlling airborne particulate matter, comprising, in combination:
- a. a short open-ended housing including a subsonic diffuser portion having an entrance and an outlet, the diffuser portion diverging from the entrance to the outlet;
- b. a liquid spray nozzle means including a pipe arranged transversely of the housing and mounting adjacent the entrance of the diffuser portion a diverging spray head disposed at the entrance of the diffuser portion for directing a diverging spray toward the outlet of the diffuser portion;
- and
- c. the housing further including air intake means connected to the entrance of the diffuser portion and forming a passage of constant cross-sectional area and of the same size and cross-sectional configuration as the entrance to the diffuser portion and simultaneously forming an extension of the entrance of the diffuser portion, the passage extending from the entrance of the diffuser substantially the same distance as the outlet of the diffuser portion extends from the entrance of the diffuser portion for mixing air with the liquid spray and forming a mist which attracts and entrains particulate matter from air adjacent the mist downstream of the diffuser portion.
