A kind of drum type brake exhaust emission control filter
Technical field
The present invention relates to technical field of purification filtration more particularly to a kind of drum type brake exhaust emission control filters.
Background technology
It is used in a variety of applications using the filter plant of dry filter, with cleaning exhaust gas or others in various industry
Device in generated exhaust gas (being commonly referred to as exhaust gas below).Dry-type filtering apparatus is relative to wet filter equipment (example
Such as rinse-system) for, what very special advantage was the foreign matter of relatively simple appearance filters out method, because these are not
It can be in conjunction in the liquid phase.
However, will have problem when in the exhaust gas that foreign matter is included in adhesion properties.Such as exhaust gas includes
Tar dirt or exhaust gas come from spray painting/painting installation, especially moist spray painting/japanning.The reason is that such viscosity is different
Object meeting preferential deposition is gradually blocked in the hole of filter.Due to their adhesion properties, they can closely be attached to
Filtering surface, and from there through the cleaning systems for using dry filter commonly used using gas-pressurized, can not incite somebody to action
It is removed from filtering surface.Thus filter is rapidly lost its cleaning capacity and must not be not replaced.
It is known that filtering can be added when dry filter is used to filter the exhaust gas of the foreign matter comprising adhesion properties
Auxiliary agent.This can be in the upstream of dry filter, by injecting filtration adjuvant in supplying the non-purified air-flow to dry filter
And it realizes.It can also coat filtering before the dirt gas side of dry filter and abnormal contact using filtration adjuvant
Surface (so-called " precoating ").The filtration adjuvant is used to establish the bonding with sticky foreign matter in exhaust gas, and ensures to coagulate
Polymers is made of filtration adjuvant with the foreign matter for being attached to substrate surface, and the condensation product can be held using traditional clean method
It changes places removal.The example of filtration adjuvant is added directly in the raw gas stream of dry filter upstream in DE4211465C2
Middle disclosure.It can for example be known from DE19715195A1 come precoating filtering surface using filtration adjuvant.In addition, above-mentioned two
In piece document, the method for providing the material for collecting generation after the cleaning of filter, and optionally in its processing
The method for enabling it be back to non-purified air-flow later.
DE19924130A1 and DE10361266A1 discloses a kind of method, wherein is generated after filter element cleaning
Material be collected in collection vessel, and collected material is stirred in collection vessel by the forced air being blown into
It mixes, so that it is attached to filtering surface again.
Invention content
In order to solve the above technical problem, the present invention provides a kind of drum type brake exhaust emission control filters, including:
Filter assemblies comprising multiple filter elements, the multiple filter element are arranged in order, and each filter element includes
Multi-layered filtering element and detecting element, the multi-layered filtering element is for filtering exhaust gas, and the detecting element is for detecting by corresponding
The filtered purification efficiency of multi-layered filtering element;
Barrel shape support element, is set in the outside of the filter assemblies, and the inside of the barrel shape support element has at least one
A fastener, hanging buckle is at least one filter element, to support the filter assemblies.
Further, the multiple filter element surrounds the inside of the barrel shape support element, and with rectangular, round or honeycomb
The mode of shape array is arranged.
Further, the multi-layered filtering element includes multiple filtering layers made of unlike material.
Further, the barrel shape support element has the inner surface contacted with the filter assemblies, the material of the inner surface
Material is selected as flexibility or the material with certain elasticity.
Further, the barrel shape support element has the outer surface opposite with the inner surface, and the outer surface is selected as
Hard material.
Further, the material selection of the barrel shape support element is gas permeable material.
Further, the drum type brake exhaust emission control filter further includes:
Alarm is connect with multiple detecting elements, for detecting corresponding multilayer filter in the detecting element
The gas that core filters out is alarmed when not up to standard.
Further, the alarm sends out sound or light alarm.
Further, it can show that the gas which filter element filters out is not up to standard simultaneously when the alarm equipment alarm.
The filter assemblies of the present invention can carry out layering to exhaust gas, to improve degree of purification and filter efficiency, and
And since with multiple filter elements, the filtering material of filtering different material can be arranged, to carry out comprehensive filtering to exhaust gas,
To obtain clean gas.In addition, a detecting element is arranged to each filter element, which mistake can be detected in time
Filter unit goes wrong, and to replace in time, and then improves degree of purification.
According to the following detailed description of specific embodiments of the present invention in conjunction with the accompanying drawings, those skilled in the art will be brighter
The above and other objects, advantages and features of the present invention.
