Is formed. The overflow water circulation path is connected to the storage tank 80, and water injection devices 90 and 100 are installed in the trickle chamber and the wind-relaxing shutter, and a part of the dust supplied from the upper side of the trickle chamber is condensed by the water spray to the storage chamber. Dropping and passing dust is dropped in the process of passing through the wind-relaxing shutter and the water spraying device, the remaining dust is filtered by the filter 110 installed in the exhaust chamber, the float floating in the storage chamber is applied to the external blowing pressure It is discharged to the float discharge port by horizontal transfer. The overflowed water from the storage chamber is overflowed through the overflow water circulation passage, filled in the storage tank, and circulated by being supplied to the injector by a pump. 120 is periodically removed.

The trickle chamber 20 is connected to the dust transfer duct 130 and a water spray device is formed therein. The water spray device 90 is vertically sprayed onto a pipe 91 attached to the wall of the trickle chamber. It has a structure in which the nozzle 92 is formed.

The dust transfer duct 130 is a duct for sucking and discharging dust inside the factory with an intake fan, and directly connecting the sucked dust to the trickle chamber or via a primary dust removing device such as a cyclone dust collector, and finally discharging dust. It is coupled to flow into the trickle chamber by connecting to the transfer duct.

The dust flowing into the trickle chamber through the dust transfer duct flows into the trickle chamber at high speed by the blowing pressure from the intake fan or cyclone, and the cross section of the trickle chamber is significantly larger than the cross-sectional area of the transfer duct. The phenomenon occurs, and in that state, the specific gravity is increased by mixing with the water sprayed from the injector, and condensation occurs between the dusts, thereby falling by gravity.

In order to effectively perform dust condensation by the injection of water, the pipe constituting the water spray device is disposed on each wall of the trickle chamber 20, as shown in FIG. 2, and a nozzle 92 formed in the pipe 91. ) Is installed so that it is directed upward and sprayed toward the falling dust.

Gumbles, which have a low specific gravity among the dusts wetted by water, float on the surface of the storage chamber, and heavy lumps or condensed dust settle to the bottom of the storage chamber.

Storage chamber 40 is configured to be inclined to the bottom so that it can be periodically discharged after receiving the precipitate 150 effectively to allow the sediment to settle towards the bottom of the center, and to discharge and remove the precipitate periodically The device forms a drain valve 120 at the top of the bottom.

Wind-relaxing shutter 50 is a device for inducing the condensation of dust through water spray in a state in which the speed of dust flowed through the transfer duct 130 is reduced and the flow is delayed by switching to turbulent state. It consists of a series of shutters 51 arrange | positioned, The water spraying apparatus 100 is installed behind each shutter.

Wind speed shutter is to effectively disturb the flow of dust by varying the direction of the blade (51a) of each shutter, the present invention, as an embodiment of the present invention arranges the shutter blades in the form of a comb, the wing of the rightmost shutter is a downflow And the blade of the intermediate shutter induces an upflow, and the next shutter is configured to adjust the direction of the blade to induce an upward flow.

According to the above embodiment, the dust flows through the trickle chamber as shown in Fig. 3, while flowing through the respective wind-relaxing shutters, the velocity decreases and is disturbed, causing more contact with the water sprayed by the water spray device. By having an effective condensation will occur.

The lower end of the shutter is lowered to a depth of about 1 cm from the water level line WL of the storage chamber so that the dust flows horizontally only through the shutter. Even in this case, the float 151 is caused by the wind pressure of the dust. It can flow horizontally while passing through the shutter blades facing the surface of the water or the lower end of the shutter, and can exit the float discharge port.

The water spraying device 100 in contact with each wind-relaxing shutter is used to gradually condense dust, etc., which has not been filtered out in the trickle chamber, and thus the nozzle 102 is placed on a series of pipes 101 vertically aligned with the shutter. It forms and serves to spray water toward the dust flow through the shutter.

Most of the dust and gum flow introduced through the transfer duct are filtered in the course of passing through the trickle chamber and the storage chamber, and the microscopic dusts, which are not filtered out, are filtered by the filter 110 installed in the exhaust chamber 30 for the final treatment. do.

The filter installed in the exhaust chamber is preferably a planetary filter useful for adsorption of fine dust, and the filter is detachably coupled to the exhaust chamber so that it can be replaced periodically.
