Description

Filter element with the honeycomb ceramics for air cleaning

Technical field

The utility model relates to a kind of filter elements.

Background technique

By 20,10/,049 052 A1 of WO it has been known that there is a kind of filter element, which is configured to so-called combined type mistake Filter.Such filter element is filtered to particle and adsorbed gas.Such filter element may be used to occupant Carriage keeps no harmful substance as much as possible.

Must make in high degree the room of building keep being safe from harm human health substance, particularly gas and steaming Vapour.Thus more and more using mobile air purifier in housework.

Under the premise of this, proposed in 10 2,013 011 457 A1 of DE: using loose form or bulk forms Active carbon.It is especially set out: to use the active carbon of particle form.The application of the active carbon of this form has passed through said combination formula Filter has long been known to everyone, these combined filters additionally show pleated structure (Faltenstruktur).

In this context, a kind of active carbon formed body as known in 101 04 882 B4 of DE, the active carbon formed body With honeycomb.Active carbon formed body is inhaled by squeezing out the mixture including active carbon and other materials and being made and be used as Attached formula filter.

A kind of other filter element as known in 101 50 062 B4 of DE, the active charcoal forming of the filter element Body, the active carbon formed body have honeycomb.

10 2,004 063 434 B4 of DE discloses a kind of other active carbon formed body with channel.

Utility model content

The purpose of this utility model is: providing filtered air without problems for space as closed as possible, wherein from The harmful substance being present in aerosol, gas, fine droplet or solia particle is almost removed in air, and is used The filter element of simple structure in a kind of structure.

According to the utility model, above-mentioned purpose is achieved using filter element comprising: main body, the main body have suitable In the material of adsorbed gas and steam, wherein main-body structure is at honeycomb ceramics, it is characterised in that: filter element is for being at least portion Closed space is divided to provide filtered air, wherein to remove from air and be present in aerosol, gas, drop or solid Harmful substance in particle.

Recognized according to the utility model: honeycomb ceramics can be realized the beneficial technical effect of the utility model: cross filtering element The very compact construction of part.It is micro- between the inflow side and outflow side of filter element to further recognize that honeycomb ceramics causes The small pressure loss and the problem of therefore seldom cause equipment aspect.Surprisedly recognize: usually used having is lived The filter element of property charcoal spherolite or active carbon particle shows the relatively high pressure loss compared with honeycomb ceramics.

In addition, honeycomb ceramics although have open channel and only because the medium and channel that need to filter wall edge flowing side To contact thus carry out the absorption of script, honeycomb ceramics but surprisedly shows good adsorption capacity (Adsorptionsleistung)。

It is that whole system is (indoor according to the volume flow of indoor air cleaner by application according to the present utility model Air purifier includes filter) reach in 30m³/ h to 1000m³Formaldehyde pure air between/h exports ratio (F-CADR) Add up purge amount with the formaldehyde of the > 1500mg of the Chinese Industrial Standards (CIS) for the indoor air-purification device for meeting GBT standard 18801-2015 (F-CCM)。

Value for other pernicious gases such as toluene or benzene is similarly positioned within the scope of this herein.

Filtered air can be provided without problems for space as closed as possible on this point, wherein from air In almost remove the harmful substance being present in aerosol, gas, fine droplet or solia particle, and use structure The filter element of upper simple structure.

Therefore the purpose that text head is addressed is achieved.

Honeycomb ceramics can have extraordinary absorption power (Adsorptionsdynamik).Therefore, according to volume flow Reached by whole system in 30m³/ h and 1000m³F-CADR between/h and the Interior Space for meeting GBT standard 18801-2015 The F-CCM of the > 1500mg of the Chinese Industrial Standards (CIS) of air purifying apparatus.

Honeycomb can be made of active carbon or active charcoal.Can easily by active carbon in the form of lotion or as The component part of lotion is extruded into honeycomb ceramics.

Active carbon share on honeycomb ceramics can be in 50 weight % between 80 weight %.Thus honeycomb has sufficient amount Active carbon and be still stable in mechanical aspects.

Channel and/or honeycomb ceramics can be configured in honeycomb ceramics can be run through by wide-open channel.It need to filter Air can flow through these channels, and not occur the apparent pressure loss between inflow side and outflow side.

Dipping portion (Impraegnierung) has can be set in honeycomb ceramics.By the way that the use model with honeycomb filter is arranged Enclosing the dipping portion to match can be further improved adsorption capacity.

Beneficial honeycomb ceramics in other words honeycomb filter include at least 55 weight % active carbon.In addition, honeycomb mistake Filter can contain attendants.Beneficial attendants are such as vitreous carbon and/or aluminosilicate.The lattice density of honeycomb ceramics, The number of channels of i.e. each square measure is preferably in 10 lattice/cm2 and 120 lattice/cm²Between, particularly preferably in 40 lattice/cm2 and 95 Lattice/cm²Between.

The wall thickness of conduit wall can be between 150 microns and 450 microns.Therefore the bee with large number of channel is realized Nest body.

The quantity in the channel in honeycomb ceramics in a beneficial manner can 40 channel/square centimeters and 100 channels/ Between square centimeter.This channel density is it is verified that be particularly useful for guaranteeing small pressure in the case where adsorbing power height Loss.

It is preferably according to the utility model:

It is provided with for honeycomb ceramics including the appropriately combined of channel density, wall thickness and active carbon share；

The space is configured to the room of building；

Filter element is the component part of portable room air filtration device.Space for example can be in house or house Space.Especially Asia, particularly China must always reliably to house carry out formaldehyde and other pernicious gases it is net Change.This purpose can be well realized in the filter element of type described herein as.

Filter element can be configured to combined filter, which has the filtration grade being filtered to particle. Fine particles such as pollen can also be filtered in this way.

Filter element can be configured to combined filter, the filter element have the filtration grade that dust is filtered and The filtration grade that aerosol is filtered.Therefore, filter element can satisfy the room air for meeting GBT standard 18801-2015 It the rank P4 or F4 of the Chinese Industrial Standards (CIS) of purification device and correspondingly applies in for example private housework, office building or public builds In building.
