Abstract
The utility model discloses a kind of air cleaning unit, comprising: casing, formaldehyde removing layer and anion releasing layer; Be provided with air inlet in the side of casing, be provided with gas outlet at the opposite side of casing, described formaldehyde removing layer and anion releasing layer are disposed side by side in casing and air inlet and gas outlet are separated; It is characterized in that, described formaldehyde removing layer comprise air filtration matrix and to be attached on air filtration matrix directly with formaldehyde generation chemical reaction remove formaldehyde coating; Described anion releasing layer comprises air filtration matrix and is attached to the modified verdelite layer on air filtration matrix.When air to be clean flows through formaldehyde removing layer, the pernicious gas such as formaldehyde and organic volatile can immediately with except formaldehyde coating generation chemical reaction, reaction speed is fast, and formaldehyde clearance is high.Meanwhile, owing to being provided with anion releasing layer in casing, make the air after purifying very pure and fresh, free from extraneous odour.
Description
Technical field
The utility model relates to air purification field, particularly relates to a kind of air cleaning unit.
Background technology
Newly purchasing in vehicle or newly-decorated house, various ornament materials capital more or less discharges some pernicious gases such as formaldehyde and organic volatile, if do not removed, will affect the healthy of people.
For eliminating the indoor harmful gas such as formaldehyde and organic volatile, the main mode adopting photocatalyst catalytic decomposition at present, but because the reaction speed of photocatalyst catalytic decomposition own is slower, and formaldehyde clearance is not high, the object of purifying formaldehyde just must be reached in conjunction with the adsorption filtration layer of Spaced distribution.The utility model patent being CN203442979U as one section of publication number discloses a kind of air cleaner, and active carbon and activated silica filter course and photocatalyst filter layer are carried out combination design.The design of this multiple filtration structure adds the volume of clarifier undoubtedly.
For reducing the volume of air purifier, in industry, also someone proposes formaldehyde removing liquid to evaporate, and utilizes the formaldehyde removing liquid of evaporation to carry out decomposing formaldehyde, if one section of publication number is for as described in the utility model patent of CN203810572U.Although this mode can reduce the volume of air purifier, the formaldehyde removing liquid after volatilization easily enters indoor and causes secondary pollution.Meanwhile, formaldehyde removing liquid needs special liquid holding device, and formaldehyde removing liquid is volatilized needs corresponding heater, complex structure.
Summary of the invention
For the defect existed in prior art, the purpose of this utility model is to provide one to have formaldehyde removing layer, goes formaldehyde efficiency high, and structure is simple, the air cleaning unit of compact.
For reaching above object, the utility model adopts following technical scheme.
A kind of air cleaning unit, comprising: casing, formaldehyde removing layer and anion releasing layer; Be provided with air inlet in the side of casing, be provided with gas outlet at the opposite side of casing, described formaldehyde removing layer and anion releasing layer are disposed side by side in casing and air inlet and gas outlet are separated; It is characterized in that, described formaldehyde removing layer comprise air filtration matrix and to be attached on air filtration matrix directly with formaldehyde generation chemical reaction remove formaldehyde coating; Described anion releasing layer comprises air filtration matrix and is attached to the modified verdelite layer on air filtration matrix.
Further illustrating as such scheme, is also provided with photocatalyst purification layer in casing, and described photocatalyst purification layer comprises uviol lamp and is attached with the air filtration matrix of photocatalyst layer.
Further illustrating as such scheme, described air filtration matrix comprises: air filtration pieces, activated charcoal strainer, one or more in activated silica screen pack.
Further illustrating as such scheme, the thickness of described air filtration pieces is 1-10mm.
Further illustrating as such scheme, described air filtration pieces is provided with the filter bores of multiple aperture between 0.1-2mm.
Further illustrating as such scheme, described modified verdelite layer is for being attached to the nano-particle layer on air filtration matrix.
Further illustrating as such scheme, described photocatalyst layer is Nano titanium dioxide layer.
Compared with prior art, the utility model has following beneficial effect:
One, by attachment on air filtration matrix directly with formaldehyde generation chemical reaction remove formaldehyde coating, when air to be clean flows through formaldehyde removing layer, the pernicious gas such as formaldehyde and organic volatile can immediately with except formaldehyde coating generation chemical reaction, reaction speed is fast, and formaldehyde clearance is high.Meanwhile, owing to being provided with anion releasing layer in casing, make the air after purifying very pure and fresh, free from extraneous odour.
Two, by increasing photocatalyst purification layer in casing, utilizing the two-layer decomposition of the pernicious gas such as formaldehyde removing layer and photocatalyst purification layer PARA FORMALDEHYDE PRILLS(91,95), the formaldehyde in air to be clean can be removed completely.
Three, whole air cleaning unit only has simple two to three layers for the treatment of facilities, compared with existing air purifier, has the advantages that structure is simple, volume is little.During practical application, the air cleaning unit that the utility model can be provided directly is installed on the air outlet of fan or air-conditioning, easy to use, and practicality is good.

Detailed description of the invention
For setting forth essence of the present utility model further, by reference to the accompanying drawings detailed description of the invention of the present utility model is described as follows.
As shown in Figure 1, a kind of air cleaning unit, comprising: casing 1, formaldehyde removing layer 2, photocatalyst purification layer 3 and anion releasing layer 4.
Be provided with air inlet 11 in the side of casing 1, be provided with gas outlet 12 at the opposite side of casing 1, described formaldehyde removing layer 2, photocatalyst purification layer 3 and anion releasing layer 4 are all disposed side by side on the inside of casing 1, and arrange successively from air inlet 11 toward direction, gas outlet 12.
Wherein, described formaldehyde removing layer 2 comprise air filtration pieces 21 and be attached on air filtration pieces 21 except formaldehyde coating 22.In the present embodiment, preferred air filtration pieces 21 is the polyethylene air filter that 5mm is thick, and air filtration pieces 21 is provided with the filter bores of multiple aperture between 0.1-2mm.Preferably except comprising amine compound, cyanamide compounds, the water-soluble high-molecular compound of hydroxyl and nano titanium oxide in formaldehyde coating 22.More specifically, the preparation relating to formaldehyde removal functional coating see a kind of formaldehyde scavenger of the applicant's earlier application (publication number is CN1695753), can repeat no more here.
Described photocatalyst purification layer 3 comprises uviol lamp 31 and is attached with the metal-air filter 33 of photocatalyst layer 32.In the present embodiment, preferred light catalyst layer is Nano titanium dioxide layer, and the thickness of preferred light catalyst layer is 4mm, and the thickness of preferable alloy air filtration pieces 33 is 6mm.
The modified verdelite layer 42 that described anion releasing layer 4 comprises air filtration pieces 41 and is attached on air filtration pieces 41.In the present embodiment, preferred air filtration pieces 41 is the polypropylene air filtration pieces that 3mm is thick, and preferred modified verdelite layer 42 is for being attached to the nano-particle layer on air filtration pieces 41.
