Detailed Description
The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:
as shown in fig. 1-2, the symbols 1-10 in the figures are respectively expressed as: the device comprises a negative conductive orifice plate 1, a positive conductive frame 2, a metal round tube 3, a discharge needle electrode 4, an insulating connecting column 5, an air inlet 6, an air outlet 7, a circulation gap 8, a conductive rod 9 and a stainless steel frame 10.
Example (b): as shown in fig. 1 to 2, the needle electrode discharge circular hole dust and bacteria removing device of the present embodiment includes a negative conductive hole plate 1, a positive conductive frame 2, a metal circular tube 3, a discharge needle electrode 4, and a power supply. The negative conductive pore plate 1 and the positive conductive frame 2 are arranged in parallel and connected through a plurality of insulating connecting columns 5. A plurality of through holes are formed in the negative conductive pore plate 1, and each metal round pipe 3 is inserted into the through hole of the negative conductive pore plate 1; one end of the metal round pipe 3 is an air inlet 6, and the other end is an air outlet 7; the air inlet 6 faces the positive conductive frame 2. One end of the discharge needle electrode 4 is a pointed end which is inserted in the metal round tube, and the other end of the discharge needle electrode 4 is connected with the grid-shaped positive electrode conducting frame 2; a plurality of circulation gaps 8 for air to pass through are formed on the positive conductive frame 2; the negative conductive pore plate 1 and the positive conductive frame 2 are respectively electrically connected with the negative electrode and the positive electrode of the power supply.
The edge of the negative conductive pore plate 1 is provided with a stainless steel frame 10; the stainless steel frame 10 may be adapted to the inner diameter of the air treatment device. The stainless steel also has the characteristic of weak conductivity, so that the stainless steel frame 10 can avoid the electric leakage degree of the shell of the air treatment device when the metal round tube 3 and the discharge pin 4 are in electric leakage, and simultaneously, the service life of the air treatment device is prolonged without replacement for the whole life.
The negative conductive orifice plate 1 and the positive conductive frame 2 are made of metal. The axes of the discharge needle electrode 4 and the metal round tube 3 are coincided, the discharge distances from the discharge needle electrode 4 to the inner wall of the metal round tube 3 are equal, a disc-shaped high-strength electrostatic field with gradually decreasing intensity from the axis to the inner wall can be formed after power is supplied by a power supply, a low field strength dead angle cannot be generated, and the ozone release amount generated due to air ionization can be effectively controlled by selecting proper voltage.
In the process that the air flows through the metal round tube 3, the electric field charge and the diffusion charge are realized when the particles in the air move in the electric field of the air, so that the particles in the air are positively charged. The discharge needle 4 and the metal round tube 3 form a disc-shaped high-intensity electrostatic field. Under the action of the electric field force, suspended particles in the air are charged to carry positive charges and are then adsorbed by the metal round tube 3 serving as the negative electrode, and microorganisms are ionized, carbonized and killed under the action of the high-strength electric field.
Specifically, the positive conductive frame 2 is formed by connecting a plurality of conductive rods 9 which are intersected in a staggered manner to form a grid shape, a gap between the conductive rods 9 is a circulation gap 8, and air exhausted from an air outlet 7 of the metal round tube 3 can pass through the positive conductive frame 2 from the circulation gap 8. The distance between the air outlet 7 of the metal round tube 3 and the positive conductive frame 2 is larger than or equal to the radius of the metal round tube 3. The arrangement mode can avoid the direct collision of the air discharged from the air outlet 7 with the positive conductive frame 2, and reduce the resistance of the positive conductive frame 2 to the air.
Specifically, the discharge pin 4 is inserted into the metal round tube 3 from the air outlet 7 of the metal round tube 3. The distance between the needle point of the discharge needle electrode 4 and the air inlet 6 of the metal round tube 3 is 1/6-1/4 of the length of the metal round tube. The reason for selecting the arrangement mode is that if the needle point of the discharge needle electrode 4 is too close to the air inlet 6 of the metal round tube 3, the ionic wind can be reduced, the corona is unstable, the ionization region can be thinned, and the positive charge and the ionization degree of the particulate matters and the microorganisms are influenced when the particulate matters and the microorganisms pass through, so that the particulate matters and the microorganisms can not be effectively ionized, or the particulate matters and the microorganisms can not be provided with enough positive charge to be absorbed by the dust collection region; if the needle point of the discharge needle electrode 4 is too far away from the air inlet 6 of the metal circular tube 3, a part of tube body of the tube cavity of the metal circular tube 3 close to the air inlet 6 cannot be matched with the discharge needle electrode 4 to generate an ionization region, the tube cavity of the section loses the use value, the region of the dust collection region is correspondingly reduced at the moment, and the dust removal effect is reduced. If the needle tip is out of range, the dust collecting effect will be reduced proportionally.
Specifically, the length of the round metal pipe 3 is not less than 1.2 times the inner diameter thereof. The one-time passing rate can be improved by limiting the length-to-inner diameter ratio of the metal round tube 3, the dust removal and sterilization efficiency is improved, and the dust removal and sterilization efficiency is 30m3In the test chamber, the removal rate of 1 hour can reach more than 98 percent. When the length-to-inner diameter ratio of the tube is less than 1.2 times, the dust collecting area in the tube cavity is short and narrow, ionized particulate matters and microorganisms cannot be completely adsorbed when rapidly passing through the dust collecting area under the influence of wind speed, and therefore the one-time passing rate is reduced. On the contrary, when the length-to-inner diameter ratio of the pipe is larger, the dust collecting area is longerThe longer the degree, the higher the one-pass rate.
Specifically, in this embodiment, the number of the metal circular tubes 3 is the same as the number of the discharge pin electrodes 4, and one discharge pin electrode 4 is inserted into each metal circular tube 3 and is coaxially disposed. The axis of the metal round tube 3 is vertical to the negative conductive orifice plate 1. The coaxial error between the metal circular tube 3 and the discharge needle electrode 4 is less than 0.1mm, so that the electric field in the metal circular tube 3 is more uniform.
Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims, and therefore, the description thereof is not repeated herein.
