Preferably, described drying tower is back taper, and described atomizer is high speed centrifugal atomization device.
Preferably, described first air cleaner and the second air cleaner are fine air filter.
Preferably, described back powder device comprises the back powder cylinder be connected with cyclone separator, the back powder pipeline be connected with the top of described drying tower, and described back powder cylinder is connected with described back powder pipeline.
Owing to have employed above-mentioned technical scheme, compared with prior art:
1, the surface area of droplet group of the present utility model is large, and needed for material, drying time is short;
2, in high temperature gas flow, the temperature of charge of moistened surface is no more than the wet-bulb temperature of drying medium, and due to rapid drying, the temperature of final product is not high, is particularly useful for heat sensitive material;
3, directly solution can be made powder-product in drying tower, be easy to realize mechanization, automation, alleviate dirt clearly and fly upward, improve work situation;
4, gas-solid mixture is separated comparatively thorough, and the thermal efficiency is high;
The powder of 5, discharging can not only be recycled, and is beneficial to protection of the environment again.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
