The invention relates to a folded air purification filter for heating, ventilating and air-conditioning, which comprises a frame and a composite gradient fiber filter screen. The composite gradient fiber filter screen is composed of a first non-woven filter material arranged on the outer layer and an inner layer The second non-woven filter material is composed of: the first non-woven filter material and the second non-woven filter material are folded and fixed in the frame after being combined through gradients. The invention changes the traditional single-layer pleated filter material into a composite pleated filter material with a gradient, so that large-scale particles in the air can enter the inside of the filter material, thereby increasing the dust holding capacity and improving the efficiency level of the filter. The clogging problem caused by the filter cake on the surface of the material can be eliminated, the airflow resistance can be reduced, and the service life of the filter can be extended.
Description
Technical field
The present invention relates to the gas purification field in the HVAC, particularly relate to a kind of HVAC Foldable air polishing filter.
Background technology
The gas purification filter that existing HVAC is used uses individual layer filtrate Foldable air filter mostly, and filter efficiency is generally G3～M5 (thick, middle effect) by existing European standard classification, and does not generally arrange the second road filter.Owing to adopt individual layer folded form filtrate, fibre fineness, the porosity of an interior filtrate that adopts of filter are identical, therefore can only be limited to the particle that captures a certain particle size range.Folded form filtrate V-arrangement arrangement makes air velocity deflection enter filtrate in addition, is subjected to inertia-responsive particle easily to accumulate in the V word bottom of filtrate in the gas, can form upwardly extending dirt cake gradually at filter material surface.Therefore cause that the effective passage section of filter material surface reduces gradually, filtration velocity rises gradually, causes filter efficiency to descend gradually, the air cleaner resistance also rises gradually simultaneously.If adopt the resistance G1～G3 that rises slowly slightly to imitate air cleaner, can be difficult to reach the requirement of surrounding air cleanliness factor because of filter efficiency is low.Shown in Figure 1 is that the Foldable air filter filters the dusty gas schematic diagram in the prior art.
Summary of the invention
Technical problem to be solved by this invention provides a kind of HVAC Foldable air polishing filter, solves blockage problem, reduction gas-flow resistance that the filter material surface filter cake forms, reaches to prolong the filter purpose in service life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of HVAC Foldable air polishing filter is provided, comprise framework and complex gradient fabric screen, described complex gradient fabric screen constitutes with second non-woven filter material that is arranged on internal layer by being arranged on outer field first non-woven filter material; Described first non-woven filter material and second non-woven filter material are by folding being fixed in the described framework in gradient combination back.
The thickness of described first non-woven filter material is thicker than the thickness of described second non-woven filter material.
The fibre diameter of described first non-woven filter material is thicker than the fibre diameter of described second non-woven filter material; The filling rate of described first non-woven filter material is littler than the filling rate of described second non-woven filter material.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the present invention compared with prior art, have following advantage and good effect: the present invention changes into the complex wrapping filtrate that has gradient with the folding filtrate of conventional monolayers, make the bigger particle of air mesoscale can enter filtering material inside, thereby the increase dust containing capacity when improving the filter clogging effect grade, solves the blockage problem that the filter material surface filter cake forms, reduce gas-flow resistance, prolong the service life of filter.

Fig. 1 is that the Foldable air filter filters the dusty gas schematic diagram in the prior art;
Fig. 2 is an overall structure schematic diagram of the present invention;
Fig. 3 is a complex gradient fabric screen structural representation among the present invention;
Fig. 4 is that the complex gradient fabric screen captures schematic diagram to particle among the present invention.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiments of the present invention relate to a kind of HVAC Foldable air polishing filter.Fig. 2 shows overall schematic of the present invention, and it mainly is made up of framework 1,2 two parts of complex gradient fabric screen.The complex gradient fabric screen 2 folding frameworks 1 that enter.Fig. 3 is complex gradient fabric screen schematic diagram among the present invention, non-woven filter material 3 thick by the outer layer fiber diameter, that filling rate is less and inner fiber diameter non-woven filter material 4 thin, that filling rate is bigger carries out the gradient stack and constitutes, and the thickness of outer field non-woven filter material 3 is thicker than the non-woven filter material 4 of internal layer, and the non-woven filter material 4 of outer field non-woven filter material 3 and internal layer is by folding being fixed in the framework 1 in gradient combination back.The present invention makes the range scale of trap particulate matter wider because employing complex gradient filtrate is compound by the different filtrates of fabric structure parameter such as fibre diameter, filling rate, thickness are carried out organic stack.Outer employing fibre diameter is thick, the less non-woven filter material of filling rate helps the particle that particle diameter is bigger in the dust-contained airflow and is packed into filtering layer, increase dust containing capacity, slow down even avoid the generation of the upwardly extending filter cake of V-type bottom end surface, prolong air cleaner service life.Internal layer employing fibre diameter is thin, filling rate is bigger, helps further capturing particle diameter smaller particles thing, improves the level of efficiency of air cleaner.Inside and outside composite filtering material adopts the gradient combination to help improving efficiency of air filter, reduces gas-flow resistance, and simple in structure, easy to maintenance.
The present invention can be according to the actual requirement to air purity of particle yardstick distribution situation and indoor occupant and equipment in the dust laden air, determine the fabric structure parameter that each layer of composite filtering material fiber is different, particle at the different scale scope effectively captures respectively, dusty gas is carried out just imitating, the middle effect, even the disposable filtering of high-medium efficient, as shown in Figure 4, dusty gas is behind process complex gradient fabric screen, large-scale particle is caught by outer field non-woven filter material, small-sized particle is caught by the non-woven filter material of internal layer, thereby produces purified gas.The mounting means of the present invention in ventilation and air conditioning system is identical with existing technology, replaces with easy to maintenance.
Be not difficult to find, the present invention changes into the complex wrapping filtrate that has gradient with the folding filtrate of conventional monolayers, make the bigger particle of air mesoscale can enter filtering material inside, thereby increase dust containing capacity, when improving the filter clogging effect grade, solve the blockage problem that the filter material surface filter cake forms, reduce gas-flow resistance, prolong the service life of filter.
