The utility model for achieving the above object, based on same design, the another kind of technical scheme of employing is: it comprises cylindrical shell 1, water supply installation 5, rotating disc 6 and motor 9; Water supply installation reaches the nozzle 11 that is connected with pipeline by pipeline, valve and constitutes, water supply installation is packed on the cylindrical shell 1, pipeline the inner of water supply installation is fixed with nozzle 11, nozzle 11 is installed in rotating disc 6 front portions, and with 6 one-tenth matched in clearance of rotating disc, and the center of nozzle 11 and rotating disc 6 is on same axis; Rotating disc 6 is fixed on the mounting bracket of the rotating shaft of motor 9 or impeller 7 that is connected with motor shaft or rotation.The surface of described rotating disc 6 can be plane or spherical structure, and is provided with tank or some spicules perpendicular to rotary disk surface of some radial arrangement on its surface.Rotating disc 6 is fixedlyed connected with key pin by axis hole with the rotating shaft of motor 9.
Motor of the present utility model be sealed and matched for 9 one-tenth be installed in the cylindrical shell 1 in stream chamber 8, is connected with prismatic pipe or pipe every between stream chamber 8 and the cylindrical shell 1, be provided with to seal every the end in stream chamber 8 and use end cap 10.
Advantage of the present utility model is in following several respects: 1, the mist pearl of this spray pattern is that radially high velocity jet does not resemble the traditional spray mode to cylinder inboard wall, mist jet in fluid, thereby, in the pipeline in the gas remaining mist pearl less.Dehydration to gas is more favourable.2, carry out the plural serial stage combination, clean-up effect is significantly improved.The parallel connection of this device is made up, and can adapt to the needs of big air quantity.3, water smoke is the centrifugal force that rotates generation by rotating disc at a high speed, makes water droplet produce collision and waits effect to produce, and pressure of supply water is not required.4, without limits to condition of water quality.The water stream channel diameter of rotating disc is relatively big, and the solid particulate matter in the water can not result in blockage.Even adopt nozzle to supply water, nozzle need not produce the mist pearl, and the aperture can be bigger, the also corresponding minimizing of possibility of jamming.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further:
Embodiment 1, and the utility model is made up of the mounting bracket of cylindrical shell 1, water supply installation 5, rotating disc 6, motor 9 or impeller 7 that is connected with motor shaft or rotation.In cylindrical shell 1, be equipped with every stream chamber 8, between stream chamber 8 and cylindrical shell 1, be connected with prismatic pipe or pipe, motor be sealed and matched for 9 one-tenths be installed in the cylindrical shell 1 in stream chamber 8, be provided with sealing with end cap 10 every the end in stream chamber 8, the interior gas of assurance and cylindrical shell is isolated fully; Between stream chamber and cylindrical shell, form the air flow channel of annular.Water supply installation 5 reaches the adapter sleeve 4 that is connected with pipeline by pipeline, valve and constitutes.Rotating disc 6 is fixed on the mounting bracket of the rotating shaft of motor 9 or impeller 7 that is connected with motor shaft or rotation.The adapter sleeve of water supply installation is installed in rotating disc 6 fronts, and adapter sleeve 4 is fixed on the support ring 2.Be separated into inlet air plenum and go out air compartment with inner core spacer ring 12 every inside, stream chamber, utilize the heat radiation of the convection current assurance motor of air.Its way of supplying water is: by coaxial with rotating disc and be connected the inner chamber that adapter sleeve 4 on the water supply line injects water rotating disc, enter the inner chamber of rotating disc when the adapter sleeve water filling after, from link to each other with inner chamber radially or in axial some water channels outside circumference direction penetrate.Do not leak during for the assurance water filling, adopt sealing device between adapter sleeve and the rotating disc.Consult Fig. 1, Fig. 3, Fig. 6 and Fig. 7.
It also can cooperate suit to constitute water-throwing disk by adapter sleeve 4 that is connected with pipeline and rotating disc 6, in adapter sleeve 4, be provided with the adapter sleeve cavity, be provided with the pipeline connecting hole in adapter sleeve cavity outer end, the inner of rotating disc 6 is provided with the rotating disc axle, the rotating disc axle becomes the movable sealing engage sleeves to be contained in the adapter sleeve cavity, be provided with the rotating disc axis hole that does not penetrate the rotating disc outer wall along rotating disc axle the inner, the inner of rotating disc axis hole is connected with the adapter sleeve cavity, water dumping hole more than 1 is set on the rotating disc, and the water dumping hole on the rotating disc is connected with the rotating disc axis hole.Consult Fig. 3, all the other are identical with above-mentioned embodiment.
Embodiment 2, and the utility model directly is ejected into water on the axial surface of rotating disc 6 by the nozzle 11 that is connected on the water supply line.Structure and Fig. 1 as Fig. 2 are basic identical, just the adapter sleeve 4 of water supply installation are changed into nozzle 11, and difference is that rotating disc 6 directly is fixed in the rotating shaft of motor 9, and water is directly injected to rotating disc 6 surfaces.Fig. 4, Fig. 5, Fig. 8 and Fig. 9 are 2 kinds of rotary disk structure schematic diagrames of rotating disc 6, and the mode of rotating disc 6 water dumping mist formations is that the radially tank by rotary disk surface produces, and can also become Surface Machining the spicule of short and small protrusion or cylinder to produce.Because of there is the spicule of some radially tanks or vertical surface on rotating disc 6 surfaces, the water droplet on it under the centrifugal action that rotating disc produces, to circumferencial direction impelling cylinder inboard wall.Because the high speed that rotating disc does not stop rotation, the water droplet that impelling goes out are because of effects such as inertial collisions, water droplet produces atomizing, forms the veil perpendicular to the cylindrical shell cross section one.The water droplet injection direction of veil is vertical with gas flow direction in pipeline or the cylindrical shell, and to the solid particle deposits yields interception function in the gas, and a grit of interception is taken to cylinder inboard wall.The globule and the viscosity between cylinder inboard wall that speckle with dust granules are bigger, and droplet constantly obtains cohesion, form current and discharge from lower mouth, thereby gas is purified.Consult Fig. 2, Fig. 4, Fig. 5, Fig. 8 and Fig. 9.All the other are with embodiment 1.
