DUST COLLECTOR

PURPOSE:To obtain a dust collector little in pressure loss and capable of utilizing effectively water for the dust collection by providing a horizontal slit-shaped spray nozzle along the peripheral surface of a lower-part conical drum in a water washing type dust collection formed with a Venturi part. CONSTITUTION:A Venturi part 2 wherein the diameter is shrnk in a conical shape is provided in the neighborhood of the center of a tubular drum 1. The spray nozzles 6a, 6b injecting water for the dust collection are provided along the peripheral surface wherein a lower-part conical drum 2a is touched to a ring slit element 4. The spray nozzles 6a, 6b are horizontally provided in a two-stage slit shape along the peripheral surface of the conical drum 2a. Therefore an exhaust gas introduced through an inlet pipe 1a is wrung in a ring slit part 5 and the flow velocity is made speedy. Simultaneously since water is introduced at right angle for the exhaust gas stream through the spray nozzles 6a, 6b, the diffusion and the inertia collision are caused and thereby the dust can be efficiently collected in the water for the dust collection.
