Venturi sprinkler for controlling smoke and apparatus for removing smoke and poisonous gas

摘要

Provided is an apparatus for removing smoke and poisonous gas comprising: a main body including a flow part for supplying water, and a nozzle connected to the flow part and having a width smaller than that of the flow part; a frame enclosing the main body and having a suction part for controlling smoke; and a heat sensitive unit fixed to seal the nozzle. When the flow part, the nozzle and the frame inject, at a high speed, a pressurized fluid through the nozzle, the fluid is injected in a vortex flow toward an inlet of a Venturi pipe-shaped mixing chamber arranged in a lower portion of the main body, and a negative pressure explained in Bernoulli's theorem is generated to form a vacuum in the space between the nozzle and the mixing chamber, thus enabling the suction of smoke and poisonous gas. The smoke and poisonous gas are mixed with water in the mixing chamber so as to be trapped in the water or dissolved and dispersed in the water. The suction part is formed in the area which encloses the nozzle such that the suction part can operate together with a vacuum ejector. The frame is arranged so as to enclose the heat sensitive unit.
