Description

Rotation drum type static air purifier

Technical field

The present invention relates to a kind of air cleaning unit, a kind of device that utilizes dust and polar molecule and compound thereof in the electrostatic field separation of air particularly is provided.

Background technology

Mainly be nitrogen and oxygen in the pure air, belong to nonpolar covalent bond molecule.After air is polluted, there are a large amount of nonpolar molecules and compound thereof, for example CO, CO ₂, NO and other hydrocarbon etc.Be subject to the electric field action principle according to dust in the air and polar molecule and carry out air cleaning, be used to improve environment and IAQ and reclaim available resource.

Utilize the technology of electrostatic depuration air to receive people's attention in recent years, successively disclose many innovation and creation, like Chinese patent 200520011650,200510063213,200320118464,200720192708 etc.These innovation and creation ubiquities can not high efficiency separation and the ability that absorbs molecular state pernicious gas and compound in the air.

Summary of the invention

The purpose of this invention is to provide a kind of rotation drum type static air purifier, add static electric field in the drum type mesh structure of this device, constitute drum type static sieve.When the air that is cleaned sieves through drum type static, dust granules and polar molecule and compound thereof in the Electrostatic Absorption air between screen cloth.Through rotation drum type static sieve, the dust granules of absorption and polar molecule and compound thereof are dissolved in the liquid below the drum type static sieve circumference.

Rotation drum type static air purifier of the present invention; Include a drum type static sieve that can in rotating shaft, freely rotate; Drum type static sieve is made up of multilayer screen cloth closed assembly, conductor wires five equilibrium placement vertically on circumference in the screen cloth, and every strip conductor wire rod is connected to external power source by resistor network.External power source is connected with each conductor wires with the transverter that is connected with circumference outer contact wire rod through the transverter that is connected with circumference inner screen conductor wires, and the resistor network between conductor wires forms air through the multi-dimensional electric field between the inner wire wire rod of space after to the external voltage dividing potential drop.Electric-field intensity is confirmed according to the spacing of conductor wires and the size of separated object particle.Separated air is got into by the middle part of drum type static sieve top, vertically through drum type static sieve, discharges from the two ends of axle.Airborne dust and polar molecule and compound thereof are adsorbed between the conductor wires under electrostatic field.Drum type electrostatic separation sieve slowly runs under the driven by motor in distributor, and the too high liquid of rotating speed is prone to get into air communication channel.With the rotation of drum type static sieve, the material that is adsorbed is sent in the liquid tank of drum type static sieve below, is collected and dissolving by the liquid in the liquid tank.Molecule that liquid in the liquid tank adsorbs as required and compound chemistry character are selected, and make when not having specific (special) requirements to use water as solution.Liquid circulates via liquid inlet and outlet or changes in the liquid tank.

Every screen cloth of drum type static sieve is pressed near the quadrature bonding forming by conductor wires and insulation wire rod, and conductor wires is in the circumferential plane separately with the insulation wire rod.One end of drum type static sieve adopts insulating polymer sealings such as resin; Through seal receptacle conductor wires is connected to the printed circuit board (PCB) in the distributor; The end of each conductor wires is welded in the circuit with resistor network, and skin is connected with rotary converter respectively with the conductor wires of internal layer.Brush on the transverter is connected external power source with the conductor wires of correspondence.External power source is divided into three independent current sources, and the two-way power supply that wherein is connected to internal layer and outer contact wire rod forms the static electric field between along the circumferential direction per two strip conductor wire rods.The Third Road power supply is connected between internal layer power supply and the outer power supply, forms radially the static electric field between every layer of screen cloth conductor wires.In the screen cloth rotary course, the liquid in the liquid tank reduces the electrostatic potential between screen cloth because surface tension can be stopped up the mesh of screen cloth.Need on drum type static sieve, electromagnetic shaker be installed, make screen cloth produce whole high-frequency vibration, shake off the liquid between screen cloth.

The size of screen cloth mesh is selected according to the volume of device and the power of electrostatic field, and device size is big, and the screen cloth mesh increases, and the voltage that adds also appropriateness increases.But after mesh increases, reduce the adsorption capacity of air Semi-polarity molecule and compound.Maximum mesh size should not make spacing between conductor wires greater than 3mm.When only being used for purifying air large-size particle thing such as dust, the spacing of mesh can be bigger.When requirement strengthens the effect of air cleaning, must increase the axial length of drum type static sieve, or adopt separated air to sieve end entering, discharge from the other end from drum type static.

Air through drum type static sieve can adopt fan forced providing, and also can be provided by the air outside supercharging device.The air that gets into drum type static sieve will leach airborne large-size particle through filter.
