In order to achieve the invariable separation speed and pressure fall even in airflows with different size, a plurality of parallel pre-separating devices (3) are arranged in the invention, wherein, at least one air valve (4) is arranged at front of these pre-separating devices (3) along the flowing direction of the airflow (2); and the air valve (4) is used for adjust the amount of the airflow flowing through the pre-separating devices (3).
Description
Technical field
The present invention relates to a kind of device that is used for filtered air stream, this device comprises that at least one preseparator and being used to after air flow is installed in preseparator that is used to isolate coarse impurities filters the filter element than small impurities.
Background technology
A kind of like this device is for example disclosed by German patent DE 689 05 389 T2.The document has been described a kind of device that is used to filter outside air, and this device has a preseparator, is used to isolate thicker impurity, like dust, pollen etc.Flow path along air stream is connected with a filter element after said preseparator.This filter element is arranged to come filtered air stream by means of some filter cores of for example being processed by suitable cellulose.These filter cores can stop that more tiny impurity particle passes through, and do not have the air of dust stream to flow out basically thereby can let.
A kind of so-called cyclone separator is disclosed in another part Germany Patent document DE 698 16 009 T2.This cyclone separator correspondingly has the guiding device of the air stream rotation that is used to make entering.Thick impurity particle such as dust etc. are brought to the outside through whirlwind and precipitate and isolate.
German utility model DE 298 19 335 U1 have described a kind of device that is used to filter extraneous air, wherein, on the flow path of air stream, are provided with a preseparator and a filter element.This preseparator is made up of a large amount of cyclone separators that is arranged in parallel.
The device of above-mentioned known type all has such shortcoming, that is, under the air stream situation of different sizes, can form the different rates of departure and pressure and fall.This for example installs for after being connected other, and air-conditioning equipment etc. is disadvantageous.
Summary of the invention
Therefore, technical problem to be solved by this invention just provides a kind of device of the above-mentioned type, under the air stream situation of different sizes, also has the constant rate of departure and constant compression force to fall even if make it.
Above-mentioned technical problem solves through a kind of device that is used for filtered air stream; This device comprises that at least one preseparator and being used to after air flow is installed in preseparator that is used to isolate coarse impurities filters the filter element than small impurities; According to the present invention; Be provided with a large amount of preseparators that are provided with in parallel to each other; Wherein, before these preseparators, be provided with at least one air door along air flow, the latter is provided for regulating the air mass flow that flows through said preseparator.
According to the present invention, be provided with a large amount of preseparators of arranging in parallel to each other.At this, there are an air door or a plurality of air door to be used to regulate air stream.The quantity of the said preseparator that said air door has therefore determined to be flow through by air, and the volume of air amount that in the official hour section, flows through said preseparator.So for example just can produce big air stream, just can be in the short time period according to device of the present invention through big volume of air amount.The quantity of the said preseparator that is flow through by air under these circumstances, also increases simultaneously.Therefore air in each preseparator stream keep constant basically, preseparator and also therefore keep constant according to the rate of departure of whole device of the present invention.In addition, can keep the air flow resistance constant, therefore on apparatus of the present invention, can form constant compression force and fall through bigger air fluoran stream surface.
More favourable scheme is that a fan that is used to produce air stream is set.This fan is connected with power supply worthily and for example can be handled by the control cabinl pulpit of rail driving.Especially can be applicable on the rail vehicles according to device of the present invention.
According to a kind of relevant with it further improvement, can said fan be arranged for the air stream that produces different sizes.Like this, for example, device of the present invention is met the different needs through improve the rotating speed of fan by an adjustable drive unit.
Along the flow direction of air stream, said fan is arranged on after the said filter worthily.
According to a kind of decision design of the present invention, be provided with some trim that rated value is according to the rules regulated each air door.Said rated value for example correspondingly is the desired volume of air flow that flows through apparatus of the present invention.At this, said trim has a rated value adjuster, utilizes the position of the said air door of its scalable, falls thereby can form predetermined pressure.
Said preseparator is cyclone separator more worthily.Cyclone separator is well-known known technology, therefore here need not this is given unnecessary details.
Description of drawings
Specify other expansion design of the present invention and advantage by the specific embodiment shown in the drawings below, in the accompanying drawing:
Fig. 1 is the sketch map of a specific embodiment of device of the present invention.
The specific embodiment
Fig. 1 diagrammatically shows a specific embodiment of apparatus of the present invention 1.This device 1 has preseparator 3 in the flow path that is arranged on air stream 2, that be designed to cyclone separator 3.Cyclone separator 3 shown in the figure is symbolically represented the cyclone separator 3 that is arranged in parallel in a large number.Along the flow direction of air, before said cyclone separator 3, be provided with air door 4.By the control device of expression is not through opening or closing this air door 4 among the figure, air stream 2 just flows through said this air door 4 cyclone separator 3 afterwards that is arranged on according to the adjusting position of this air door 4.The adjusting position or the opening degree of said air door 4 depended in the cross section of the free flow of whole cyclone separator therefore.
After said cyclone separator 3, be provided with filter element 5, the latter for example has conventional filter element.Filter element itself is known for those of ordinary skills, therefore here need not this is given unnecessary details.After said filter element 5, be provided with the transformable fan 6 of rotating speed.This fan 6 is driven by energy feed unit 7.
Device shown in the figure for example is before parts on the rail vehicle and the room ventilation equipment that is arranged on this rail vehicle.This device is used to suck outside air.The air of outside at first gets in the said preseparator 3 according to the enable possition of air door 4.In this preseparator 3, the air of coming in from the outside is by preliminary purification, and suspended particulate that thus will be thicker, dust etc. are removed from air stream 2.Then, air stream 2 flows through said filter element 5 and filter element thereof, and meticulousr impurity particle is blocked based on the pore size of the filtration system that is adopted in this air stream 2.At last, air stream 2 is through fan and leave said device 1.Like this, just the surrounding air after purifying is provided for the room ventilation equipment after being connected.
Therefore, said air stream for example is arranged on one during worthily for the said apparatus of the present invention in the duct-like housing flowing through, but all regulated at will fall in isolation of purified speed, filtration grade and the pressure of apparatus of the present invention.Therefore said preseparator 3 has a transformable effective cross section, and the effective cross section looking the open degree of said air door 4 and change is perhaps arranged or rather.Therefore pressure according to device of the present invention fall and can select in advance.In addition, also can be different air stream according to device of the present invention constant degree of purification is provided.
