A resonance type space particle purification device and control method

Abstract

The invention discloses a resonance-type space particulate matter purifying device and a control method. The resonance-type space particulate matter purifying device comprises a pair of resonance driving plates arranged in parallel, an adsorption plate, a controller, a high voltage pulse modulator and an adjustable negative high voltage power source. The high voltage pulse modulator and the negative high voltage power source are both electrically connected with the controller. Two output ends of the high voltage pulse modulator are connected with the two resonance driving plates through wires correspondingly, and the negative voltage output end of the adjustable negative high voltage power source is connected with the adsorption plate through a wire. An area between the pair of resonance driving plates arranged in parallel forms a resonant cavity. The adsorption plate is located under the resonant cavity. The high voltage pulse modulator generates bipolar SPWM high voltage pulses. According to the resonance-type space particulate matter purifying device and the control method, particulate matter can be resonated through the resonant cavity, interaction force of the particulate matter is enhanced, and thus the adsorption effect of the space particulate matter is improved obviously. By combining the resonant cavity with a negative voltage electric field, the structure is simple, installation is made convenient, and meanwhile the efficiently-mute characteristic is achieved.

Description

technical field [0001] The patent of the present invention relates to the technical field of environmental governance, in particular to a resonant space particle purification device and a control method. Background technique [0002] my country's economy is developing rapidly, people's living standards are constantly improving, and the public is enjoying the fruits of economic development. However, rapid industrialization and urbanization have led to rapid energy consumption, high population concentration, and ecological environment damage. Unscientific development has brought serious consequences. Air quality continues to deteriorate, directly causing many cities across the country to be shrouded in "smog". Environmental governance caused by "smog" has attracted much attention, so there is an urgent need for an efficient and universal particle control device and method. [0003] Existing patents on smog control methods, such as patents with publication numbers CN104591519A...

However, rapid industrialization and urbanization have led to rapid energy consumption, high population concentration, and ecological environment damage. Unscientific development has brought serious consequences. Air quality continues to deteriorate, directly causing many cities across the country to be shrouded in "smog". Environmental governance caused by "smog" has attracted much attention, so there is an urgent need for an efficient and universal particle control device and method

[0003] Existing patents on smog control methods, such as patents with publication numbers CN104591519A, CN104826431A, CN103394275A, CN104248899A, CN103977650A, CN204739608U, control smog from the source, use sludge to absorb or water-soluble soot, etc., before exhaust gas is discharged into the atmosphere Purification of exhaust gas is carried out before the process. Although this method of controlling smog from the source is also a mature and commonly used method, it is relatively targeted and difficult to achieve general use.

For example, patents with publication numbers CN204987301U, CN203916378U, CN204307493U, CN105879522A, CN105999922A, CN104511218A, CN104815496A, and CN104410706A use spraying to carry out wet deposition of smog, thereby reducing the concentration of space particles. Control the smog, but it is a waste of water resources

For example, the patents whose publication numbers are CN105986559A and CN104454100A use a blower or the like to blow the smog away by the wind to control the smog. This method can reduce the smog to a certain extent, but it has higher requirements on the wind force.

For example, patents with publication numbers CN104190168A, CN105013271A, CN104846770A, CN104844307A, CN104437861A, CN205517048U, and CN105642060A purify the air, inhale smog, and discharge clean air after purification. This method is more commonly used, but the scope of treatment is small, and it is suitable for local haze removal

For example, in the patent with the publication number CN105642443A, the method of magnetizing the mist and then using electrostatic adsorption is very novel, but this method has no effect on particles that cannot be magnetized
