Abstract
The utility model relates to a folded air purification filter for heating, ventilating and air conditioning, which comprises a frame and a composite gradient fabric screen, wherein the composite gradient fabric screen is composed of a first non-weaving filter material arranged on the outer layer and a second non-weaving filter material arranged on the inner layer, and the first non-weaving filter material and the second non-weaving filter material are fixed in the frame in folded mode after being performed with gradient combination. The folded air purification filter adopts the gradient composite folded filter material to take place of the traditional single-layer folded filter material so that grains with large sizes in the air can enter the interior of the filter materials, accordingly dust-holding capacity is increased, grade of filter efficiency is improved, the problem of blocking caused by filter cakes on the surface of the filter materials is solved, airflow resistance is reduced, and service life of the filter is prolonged.
Description
Technical field
The utility model relates to the gas purification field in the HVAC, particularly relates to a kind of HVAC and uses the 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 get into filtrate in addition, receives inertia-responsive particle to be prone 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 sketch map in the prior art.
Summary of the invention
The utility model technical problem to be solved provides a kind of HVAC and uses the 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 utility model solves the technical scheme that its technical problem adopted: provide a kind of HVAC to use the Foldable air polishing filter; 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 through gradient combination after folding being fixed in the described framework.
The thickness of described first non-woven filter material is than the thicker 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 utility model compared with prior art has following advantage and good effect: the utility model is changed into the complex wrapping filtrate that has gradient with the folding filtrate of conventional monolayers; Make the bigger particle of air mesoscale can get into 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.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The embodiment of the utility model relates to a kind of HVAC and uses the Foldable air polishing filter.Fig. 2 shows the overall schematic of the utility model, 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 a complex gradient fabric screen sketch map in the utility model; 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 through folding being fixed in the framework 1 after the gradient combination.The utility model makes the range scale of trap particulate matter wider because employing complex gradient filtrate is compound through 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 gradient combination to help improving efficiency of air filter, reduces gas-flow resistance, and simple in structure, easy to maintenance.
The utility model 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; Confirm the fabric structure parameter that each layer of composite filtering material fiber is different; Particle to the different scale scope effectively captures respectively, and dusty gas is carried out the disposable filtering of effect, middle effect even high-medium efficient just, and is 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, and small-sized particle is caught by the non-woven filter material of internal layer, thereby produces purified gas.The mounting means of the utility model in ventilation and air conditioning system is identical with existing techniques, and replacement is with easy to maintenance.
Be not difficult to find; The utility model is changed into the complex wrapping filtrate that has gradient with the folding filtrate of conventional monolayers, makes the bigger particle of air mesoscale can get into filtering material inside, thereby increases 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.
