The patent No. is that 200810030063.6 Chinese patent discloses " a kind of no-ozone cleanable electrostatic dust collector ", a kind of no-ozone cleanable electrostatic dust collector, contain ionized region, accumulation area, high-voltage ac power and high-voltage DC power supply, ionized region is above accumulation area, high-voltage ac power is connected with ionized region, and high-voltage DC power supply is connected with accumulation area.Adjacent animating electrode sheet is different the two poles of the earth, and the collecting electrode sheet is fixed on the housing by screens, and alternate collecting electrode sheet connects by conductive material, and making adjacent collecting electrode sheet is different the two poles of the earth.But this device high-efficiency dust collecting, almost ozone free produces, no accumulation of static electricity, safety and environmental protection, of many uses.
Above patent has adopted conductive material, in the time of still because of conduction, runs into the danger that abnormal conditions may occur discharging.Material is thicker in addition, and the sheet number that can use is less, and unit volume inner filtration area is limited, thereby filter efficiency also is affected, and can not wash, and can't use for a long time efficiently.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes prior art, provides a kind of simple in structure, easy to manufacture, high efficiency electrostatic dust removal filter capable of washing safely and efficiently.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of high efficiency electrostatic dust removal filter capable of washing, comprise electric conduction of carbon fiber paper 1, frame 6, fixture 7, electric conduction of carbon fiber paper 1 is fixed in the frame 6 by fixture 7, its structural feature is: the outside of electric conduction of carbon fiber paper 1 is provided with insulating barrier 4, and electric conduction of carbon fiber paper 1 is electrically connected with external power source.
Above-mentioned electric conduction of carbon fiber paper 1 is made up of paper substrates 2 and carbon fiber 3, and carbon fiber 3 directionally is fixed on paper substrates 2.
The resistance of above-mentioned electric conduction of carbon fiber paper is less than 1000 Ω/cm

The electric conduction of carbon fiber paper 1 that above-mentioned outside is provided with insulating barrier 4 each other be spaced apart 0.5-5mm, the voltage of connection is 2KV-20KV, its dielectric voltage withstand is greater than 4000V.
Fixing of electric conduction of carbon fiber paper 1 interval by fixture 7, and be placed with felt pad 9 therebetween.
The beneficial effects of the utility model are:
1, adopt the two layers of conductive material of different resistance, the generation that can effectively keep electrostatic field, and coat by insulating barrier, can switch in short distance produces very high electrostatic field, and the increase dust catching efficiency is avoided the danger of discharging and the generation of ozone free simultaneously.
2, adopt paper as electric conductor, therefore can accomplish the thickness that 0.5mm is following, can in limited space, increase the sheet number of control of dust to greatest extent, increase filter area, improve filter efficiency.
3, adopt the fixed interval part, can keep the position relative fixed between the different conductive materials,, thereby further guaranteed strainability with the generation of assurance uniform electric field.
4, conductive material adopts insulating barrier capable of washing to coat, make when laying dust is too much on the whole filter convenient for cleaning, thereby can for a long time efficiently use.
5, design of the present utility model need not the structure of existing cleaner is changed especially, and portability and applicability are strong, can be extensive use of.
