Air jet for removing polluting oil

Abstract

The present invention relates to an air jet for removing pollutant oil, and more particularly to an air jet capable of removing oil deposited on a small mud flat, sand or sedimentary soil in a coastal or inland area by injecting compressed air to float the oil on the water surface together with gas discharge. The air jet comprises: a hollow cylindrical air pipe open at both ends, the air pipe serving as a channel through which injected compressed air moves; a communication pipe having a diameter smaller than that of the air pipe and penetrating the air pipe to communicate the inside and outside of the air pipe, the outside of the air pipe being connected with an air hose for supplying compressed air; and an injection nozzle coupled with the communication pipe in the air pipe, the injection nozzle serving to accelerate compressed air supplied to the communication pipe and to rapidly inject the compressed air through the air pipe to an area polluted with oil.

1 . An air jet for removing pollutant air, comprising:
 a hollow cylindrical air pipe open at both ends, the air pipe serving as a channel through which injected compressed air moves;   a communication pipe having a diameter smaller than that of the air pipe and penetrating the air pipe to communicate the inside and outside of the air pipe, the outside of the air pipe being connected with an air hose for supplying compressed air; and   an injection nozzle coupled with the communication pipe inside the air pipe, the injection nozzle serving to accelerate compressed air supplied to the communication pipe and to rapidly inject the compressed air through the air pipe to an area polluted with oil.   
     
     
         2 . An air jet for removing pollutant air, comprising:
 a plurality of hollow cylindrical air pipes which are open at both ends and arranged in parallel, the air pipes serving as channels through which injected compressed air moves;   a coupling member serving to fixedly couple the air pipes to each other;   a communication pipe having a diameter smaller than that of the air pipes and penetrating the air pipes to communicate the inside and outside of the air pipes, the outside of the air pipes being connected with an air hose for supplying compressed air; and   a plurality of injection nozzles coupled to the communication pipe inside the air pipes, the injection nozzles serving to accelerate compressed air supplied to the communication pipes and to rapidly inject the compressed air through the air pipes to an area polluted with oil.   
     
     
         3 . The air jet of  claim 2 , wherein the communication pipe consists of: a plurality of penetration pipes penetrating the respective air pipes; a plurality of discharge pipes which are connected to the respective penetration pipes inside the air pipes and to which the injection nozzles are coupled; and a manifold which connects the penetration pipes outside the air pipes with an injection pipe connected to the air hose. 
     
     
         4 . The air jet of  claim 1 , wherein the injection direction of the injection nozzle is directed toward one or both open ends of the air pipe. 
     
     
         5 . The air jet of  claim 2 , wherein the injection direction of the injection nozzle is directed toward one or both open ends of the air pipe.
