Utility model content

The task of the utility model is to provide a kind of filter device for moveable equipment, can be realized difference Filter element and the coordination of the optimization of different filtration duties.

The task is solved using the feature of the utility model.

According to the filter device of the utility model, it is used for moveable equipment, the filter device to have at least one Moveable equipment is arranged in first filter element and the second filter element, first filter element and the second filter element In air-deflector, wherein one of two filter elements are configured to folder filter and another filter element is configured to inhale Attached filter, wherein the filter element is directly constituted adjacent to one another, wherein folder filter is configured to particle filtering Device and adsorption filter are configured to honeycomb filter, and the honeycomb filter has multiple channels, and the channel passes through Conduit wall limits.

In order to solve the task, filter element constitutes individually from one another and directly adjacent to one another in air-deflector Middle assembly.It can also be envisaged that in one and identical frame part particulate filter and honeycomb filter combined side Case.Alternatively, honeycomb filter and particulate filter can also be directly mutually bonded.Thus particulate filter and honeycomb are generated The function of formula filter separates, so that two filter elements can design independently of one another.Honeycomb filter can be with herein It designs in this way, so that can be realized the high strainability for the air stream that guidance passes through in small pressure loss.

Particulate filter can be configured to folder filter in advantageous further composition, have by on-woven At least one layer made of object, fiberglass media or diaphragm medium (such as with PTFE membrane or nanofiber diaphragm).Equally It is contemplated that the combination (all-glass paper for example including synthesis share) of different media.The collapsible mistake being made of adhesive-bonded fabric Filter is low cost and has high strainability based on relatively large filter surfaces.

Honeycomb filter has many channels, and the channel is limited by conduit wall.Such filter has special Low air drag.High filtration surface is generated by the multiple channels limited by conduit wall simultaneously, this causes extra high gas Strainability.Honeycomb filter can be special about desired air drag and the special applications well of desired gas absorption power Surely it is conditioned.External dimensions, length and the quantity in channel and the cross section in channel can be modified thus.

Honeycomb filter can with blockiness be constituted, wherein multiple sections are in the form of honeycomb ceramics in keeping frame It keeps and is assembled into honeycomb filter.Keep frame that can for example be molded manufacture.

In a kind of implementation modification for keeping frame, the holding frame is constructed by least two sections, wherein institute Stating section is part enclosure, especially half-shell.The section herein basic configuration especially having the same, i.e. equivalent and It can be connected with each other turnablely.The hinge of jointing can be set thus.It can make the assembly of holding frame frame due to being segmented It is further simplified.

It is regarded as particularly advantageously, section clamping lock each other, that is, by locking or clamping interconnection, by tensioning Element is mutually tensioned or mutually tightens.

Honeycomb filter can have active carbon.Here, filter element can be formed by active carbon completely.Alternatively It is contemplated that active carbon is mixed with other absorbent materials.Herein especially it is contemplated that the use of silicic acid.Activity The mixture of charcoal or active carbon and silicic acid mixes with bonding agent and is formed as honeycomb filter.Such filter, which has, to be used In the high strainability for removing undesirable gaseous component part.

Advantageous honeycomb ceramics or honeycomb filter have the active carbon of at least 55% weight.Furthermore honeycomb filter can To include attendants.Advantageous attendants are, for example, vitreous carbon and/or aluminosilicate.The cell density of honeycomb ceramics, also The number of channels of i.e. every surface elemant is preferably 10 to 120 cell/cm2, particularly preferably 40 to 95 cell/cm2 Between.

Honeycomb ceramics may be equipped with dipping.It can be into one by the way that the dipping being adapted to the use scope of honeycomb filter is arranged Step improves absorption property.

Honeycomb filter can form fluid rectifier.Especially generate enter air homogenization, if it is described into If entering relatively long channel of the air by honeycomb filter.Noise is reduced by the rectification of fluid, to reduce entrance The noise emission of air guidance.

Indoor air filtration instrument including the filter device according to the utility model for moveable equipment has Air delivery unit and filter device, wherein the filter element streamwise of filter device is seen individually or be can be set by group Before or after air delivery unit.In this design advantageously, the transport that gets into the air particle such as dust and Pollen is prevented from by the first filter element.Another filter element removes gaseous component part from getting into the air.By sky The gaseous component part of gas supply unit transmitting is also included and (falls into wherein).

Not only first filter element of the particularly effective separation of particle but also pernicious gas in folder filter form It is generated in the case where combination with the second filter element of honeycomb filter form being separately formed.

In a kind of alternative design, the first filter element is configured to prefilter and in the first filter element and the Third filter element can be set between two filter elements.The first filter element can be used as coarse filter herein, and second crosses filtering element Part is as adsorption filter and third filter element is constituted as fine filter.In this design, draw with into air The particle led is prevented by the filter element for being configured to coarse filter.Finer particle, especially first in moveable equipment The particle generated in into air guiding device passes through the filter element, the preferred third filter element quilt that are configured to fine filter It prevents.It is also contemplated that honeycomb filter is assemblied in front of particulate filter.Undesirable gaseous attendants are by bee Socket filter prevents.

Multiple filter stages are set in another alternative design.

Advantageously, the active charcoal of adsorption filter.

Advantageously, adsorption filter forms fluid rectifier.

Advantageously, it constitutes to honeycomb filter range selector, wherein multiple sections are keeping frame in the form of honeycomb ceramics It is middle to keep and be assembled into honeycomb filter.

Advantageously, the holding frame is to be molded manufacture.

Advantageously, the moveable equipment is implemented as portable indoor air filtration instrument.

According to the indoor air filtration instrument of the utility model, the indoor air filtration instrument has air delivery unit With the filter device according to the utility model.

Advantageously, the indoor air filtration instrument has the equipment for air wetting or sets for what is heated and cool down It is standby.

Advantageously, according to the indoor air filtration instrument of the utility model, the indoor air filtration instrument is equipped with third Filter element, wherein the first filter element can be used as prefilter composition, and the second filter element is constituted simultaneously as adsorption filter And third filter element is constituted as fine filter.

Moveable equipment can be portable indoor air filtration instrument/indoor air cleaning instrument device or combined instrument (indoor air cleaner, air humidifier, air-conditioning) is used for the filtering and purification of the air in the room of building.
