Description
(1) technical field
The utility model relates to a kind of device that enclosure space is carried out air cleaning, especially a kind of air purifier of new generation with functions such as high-pressure electrostatic precipitation and photoelectrocatalysis.It can remove particles such as volatile compound, dust, is applicable to fields such as indoor air purification, environmental protection and health care
(2) background technology
There is defective in known high-pressure electrostatic control of dust technology in application, promptly can only can not be at volatile compound at pollutants such as dust granules.Chinese patent application CN1830573A provides improved high-voltage electrostatic field, and it activates titanium dioxide at coated photochemical catalyst on the electrode under the electric field catalysis effect, to satisfy the effect of removing volatile compound.Yet still there is defective in this improved electric field, and the photochemical catalyst in that electrode surface applies comes off easily, and nano material comes off and causes secondary pollution, and there is very big potential safety hazard in human body.
(3) summary of the invention
The purpose of this utility model is to provide a kind of photocatalysis and the higher air cleaning unit of dust catching efficiency.
The utility model is achieved by the following technical solution:
A kind of air cleaning unit, comprise at least one group of sparking electrode and cylindric collecting electrode with discharge part, be provided with high-tension circuit between sparking electrode and the collecting electrode, the port of export of described collecting electrode or inner chamber are provided with the photocatalysis load, and photocatalysis load surface is provided with titanium dioxide layer.
Sparking electrode discharge generation corona zone, dust granule and contaminant molecule are attracted on the barrel through collecting electrode the time through electric charge on the corona zone band, have finished the process of control of dust; Volatile compound is through the photocatalysis treatment district, because the UV-activated photocatalysis that electric field action produces down, decomposing pollutant, this process advantages of simple.Promptly do not influence dust collecting effect, can satisfy the effect of removing volatile compound again.
Above technical scheme can be further improved by following measure:
Described photocatalysis load is made by one in plastics, sponge, ceramic foam plate or the glass.
The cross section of described photocatalysis load is circular, or cross, or the rice font, or the H type, or emitting shape, or cellular.
Described photocatalysis load is filled in the collecting electrode, photocatalysis load and collecting electrode interference fit.
Described photocatalysis load one end is buckled in the port of export of collecting electrode.
For further strengthening light-catalysed effect, the downstream of described photocatalysis load is provided with another sparking electrode, and two sparking electrodes lay respectively at the collecting electrode two ends.Because the photocatalysis load itself has certain windage, add that the additional wind-force effect of machine is far longer than ion wind, therefore second ion wind that sparking electrode produced can not flow backwards and form against the wind.
Described sparking electrode is wire, and described photocatalysis load is cylindric, and collecting electrode and photocatalysis load all sky are enclosed within outside the sparking electrode.Because sparking electrode evenly discharges to whole collecting electrode, therefore can realize that at front end control of dust purifies, can realize the photoelectrocatalysis reaction in the rear end, wire electrode can be fixed with spring.
For making things convenient for the collecting electrode dismounting to clean, described sparking electrode is contained on the support, and this support passes collecting electrode and photocatalysis load.
Described photocatalysis load is a support, and described sparking electrode is contained on this support, and described support and sparking electrode are located in the inner chamber of collecting electrode.Described sparking electrode is wire.
The utility model is simple and compact for structure, and cost easy to manufacture is low, photocatalysis and dust catching efficiency height, and it is little to take up room.
