Accompanying drawing explanation
Fig. 1 is the structural representation of sound wave demister of the present invention;
Fig. 2 is the absorption tower front view of sound wave demister of the present invention.
Detailed description of the invention
For the benefit of to the understanding of structure of the present invention, below think and coordinate drawings and Examples to be described.
Composition graphs 1 is with shown in Fig. 2, sound wave demister of the present invention, adopt low frequency high energy sound wave, be arranged on the support component on absorption tower wall 1, absorption tower wall 1 has a support component at least, sound wave demister comprises horn-like sound wave diffuser 2, sonic generator 3 and compressed air supply and purifier 4, horn-like sound wave diffuser 2 is located in tower, and fixed by bolt 5 and absorption tower wall 1, sonic generator 3 is located at outside tower, compressed air supply and purifier 4 comprise tube connector 41, pneumatic even part 42, y-type filter 43 and magnetic valve 44, the pneumatic part 42 that connects is provided with a Pressure gauge 45, in order to measure air pressure, pneumatic even part 42 is connected to one end of tube connector 41, y-type filter 43 was connected by articulation 46 with pneumatic company between part 42, and between articulation 46 and y-type filter 43, be provided with a ball valve 47, this ball valve 47 controls y-type filter 43, the other end of tube connector 41 is provided with magnetic valve 44, magnetic valve 44 is fixed by fixed head 48 and tube connector 41, wherein, sonic generator 3 is connected by a crossover sub 6 with tube connector 41, in order to adjust air pressure and air inlet, one end of sonic generator 3 is located in the entrance of absorption tower wall 1, and one end of tube connector 41 is provided with a switch valve 7 in the pneumatic outside connecting part 42, in order to control compressed-air actuated entering.
