Abstract

The utility model discloses a high-voltage static electricity dust remover for air purifier. The double-region electric field is formed by the pole matching of a honeycomb board 1 and a needle bar 2. The needle bar 2 is composed of a needle type segment 4 and a rod type segment 5. A discharge region is composed of the needle type segment and a honeycomb wall. A dust collection region is composed of the rod type segment and a honeycomb wall. The electric ionizing and the dust collection can be respectively carried out in the two electric fields. The utility model has the advantages of large area of dust collection, small damage, small occupation space, simple production process and low cost.

Description

High-voltage static electricity dust remover for air purifier

The utility model belongs to electrostatic dust collection equipment, makes the field in particular for room air dust and bacteria removing cleaning equipment.

The electrostatic generator that is used for indoor air cleaner, compare with industrial electrostatic dust collection equipment, be subjected to the restriction of two aspects: the one, the restriction of space size, the spatial volume of indoor air cleaner electrostatic generator is as far as possible little, to satisfy gas purifier in the bijou appearance requirement of indoor use, therefore used electric field should have bigger efficient-dutycycle; Restriction on the other hand derives from the low noise requirement of use, therefore in comprising the air purifier parts of electrostatic field, all should reduce the resistance loss of gas coming through as far as possible, to reduce noise, the power of blower fan is selected in also corresponding reduction simultaneously for use, reduces daily expending.The electrostatic equipment of present commercially available air purifier generally adopts the fine rule discharge to gather dust or netted discharge is gathered dust, and this dual mode is all taken into account above 2 points unsatisfactorily, and the former efficient-dutycycle is low; Latter Yi Yin micronic dust is clogged and flow resistance is raise.

The purpose of this utility model is, overcome the above shortcoming of prior art, design a kind of efficient-dutycycle height, indoor air cleaner electrostatic precipitation, bactericidal device that the gas flow resistance is little, and make it to have advantage rational in infrastructure, that energy consumption is low, manufacturing process is simple, with low cost.

The purpose of this utility model is to realize by following design.

The electrode of electrostatic field part is become by honeycomb plate, needle bar utmost point combo, is fixed on needle bar on the needle bar frame and inserts geometric center position at honeycomb, and needle bar has needle-like section and bar-shaped section two parts.

After adopting above design, the performance of electrostatic precipitator has obtained tangible improvement, adopts compact hexagon end face structure, compare with other end face structure, and the mechanical strength height, therefore unit space volume specific collection area maximum has higher efficient-dutycycle; By pin section shape and the bar-shaped section needle bar formula discharge electrode of forming, both had that fine rule discharge electrode corona current is big, tip portion not dust stratification, advantage that rate of ionization is high, also have the characteristics that major diameter discharge electrode field intensity is even, current density is big, needle-like section and bar-shaped section formation two-region electric field structure, needle-like section and cell walls are formed region of discharge; Bar-shaped section and cell walls composition dust collection section, the two-region structure makes ionization and gathers dust carries out in two electric fields respectively, has both helped the charged of aerosol dust and migration, is easy to make the diffusional charging of submicron order (＜0.4 μ m) bacterium again.

Fig. 1 is a basic block diagram of the present utility model, and the hexagon end face honeycomb 6 that is made by sheet copper links and rabbets into honeycomb plate 1, and for for simplicity, the part honeycomb that only draws among the figure, in fact whole honeycomb plate 1 are piled up by honeycomb 6 phase embeddings and formed.Be fixed on needle bar 2 on the needle bar frame 3 and insert geometric center position at honeycomb, needle bar 2 has needle-like section 4 and bar-shaped section 5 two parts.

In implementing experiment, the honeycomb needle bar adopts the thin space structure, and homopolarity is apart from 25mm, and electric-field intensity 8kv, electric field produce effective corona, air velocity＞2m/s continuously; When dust collection rate＞95%, resistance is decreased and is 2-3mmH ₂The O post.

Though the utility model honeycomb needle bar two-region electrostatic precipitator is to propose at the Electrostatic Treatment purpose to the very severe indoor air cleaner of volume and noise requirement, but its application is far above on indoor air cleaner, in fact, in other industry and civilian dedusting field, the utility model all has use widely.

Claims

1, a kind of high voltage electrostatic dust precipitator is made up of power supply, electrode etc., it is characterized in that, its electrode part, become by honeycomb plate 1 needle bar 2 utmost point combos, be fixed on needle bar 2 on the needle bar frame 3 and insert geometric center position at honeycomb 6, needle bar 2 has needle-like section 4 and bar-shaped section 5 two parts.
