Abstract
The invention discloses a kind of " herringbone " array air filter, including filter frame and 1 group is with upper filter, Combination filter element, filter core with one it is horizontally-arranged be 1 group, every group is made of several filter cores and Combination filter element.Herringbone is arranged using Combination filter element as the top of herringbone, Combination filter element is made of two filter cores of the V-type being connected to form in windward side, the filter core of herringbone two-arm is respectively arranged parallel, and the plane and ventilation end face that each filter core air inlet face is formed keep an angle, and filter flow area increases.Under the premise of not increasing auxiliary filtration apparatus, filter efficiency is improved, while meeting the needs of ventilation filter cleannes, while suitably reducing ventilation resistance, improves drafting efficiency.
Description
Technical field
The present invention relates to a kind of new air filters, belong to field of fluid machinery.
Background technique
Existing all types of labyrinth type filters or inertial filter, are all made of filter core and frame, and the cloth of filter core
Set that be all perpendicular to ventilating surface stay aligned in a row or multiple rows of.In the case where not increasing other accessory filtration equipment, such filter
Sand and dust filter efficiency approximation and ventilating surface average flow velocity at quadratic power parabolic relation, and as mean flow rate is got over
Greatly, filter efficiency is lower.In order to obtain enough filter effects, filter ventilating surface needs are increased accordingly.
On locomotive or motor-car, to the limited space that filter provides, many occasions cannot provide big lead to filter
Wind area, the filter efficiency for sacrificing filter of finally having to；Or increase auxiliary filtration apparatus, ventilation can be obviously increased in this way
Resistance is lost more than gain.
Summary of the invention
Technical problem solved by the invention is to provide a kind of " herringbone " array air filter, assists not increasing
Under the premise of filtering equipment, filter efficiency is improved.
The technical solution adopted by the present invention is that a kind of " herringbone " array air filter, including in frame and frame extremely
Few row's filter core, it is characterised in that: have cartridge combination in frame, filter core is in circular array, and the top of herringbone is a combination
Filter core, Combination filter element are made of two filter cores of the V-type being connected to form in windward side, the plane that each filter core air inlet face is formed with
Filter end face of divulging information keeps an angle of inclination beta, 0 ° of 90 ° of < β <, retention gap between the filter core between two neighboring herringbone,
Retain a direct current region, filters more than two rows of filter cores, front and back direct current region is staggered mutually.
The invention has the advantages that arranged by the herringbone of filter inner filter core, not plus auxiliary filtration apparatus, together
When meet the needs of ventilation filter cleannes, while suitably reducing ventilation resistance, improve drafting efficiency.
Detailed description of the invention
Fig. 1 is the diagrammatic cross-section of " herringbone " array air filter of the invention.
In the figure, it is marked as 1- filter core, 2- frame, 3- Combination filter element, 5- filter ventilation end face, 61- direct current, 62- oblique flow.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
Referring to Fig.1, product of the present invention mainly includes with flowering structure: 1 set of filter frame 2 and 1 group is with upper filter 1, combination
Filter core 3 form, filter core with one it is horizontally-arranged be 1 group, every group is made of several filter cores and Combination filter element.Herringbone arrangement is to combine filter
Core is the top of herringbone, and Combination filter element is made of two filter cores of the V-type being connected to form in windward side, and the filter core of herringbone two-arm is each
From being arranged parallel, the plane and ventilation end face that each filter core air inlet face is formed keep an angle.
Filter core 1 and Combination filter element 3, it is diagonally disposed according to herringbone, the air intake surface of wide L is changed to the oblique air inlet of wide S
Face.The inclination angle of the face S and filter ventilation end face is β.Angle of inclination beta makes straight-flow air be changed into oblique flow, increases through flow cross section
Product.Ignore filter core THICKNESS CALCULATION flow area, it is assumed that filter height h, and filter element is completely the same, filter core consistency
Unanimously, then newly the flow area of design filter is Sh, and the flow area of existing structure filter is Lh.It can by trigonometric function
Know, S=L/cos β, the as normal filtration device structure at β=0 °, at 0 ° 90 ° of < β <, cos β < 1, i.e. S > L, filtering
Device flow area increases.Air end face average speed is that flow removes filter end face flow area, new to design under filter speed
Drop.According to filter sand and dust filter efficiency and air velocity at the relationship of quadratic power negative correlation, newly designing filter be can be improved
Sand and dust filter efficiency.
It will be seen from figure 1 that be connected two herringbones between filter core between keep certain interval, remain a part of direct current
Region, the partial region cannot amplify flow area, i.e., newly the design increased flow area of filter will be less than (cos β -1) times.
Such as example shown in Fig. 1, under β=45 °, average every 6 channels have 4 channels to be changed to oblique flow, and 2 channels are still
Direct current is so kept, then newly designs 1.276 times that filter flow area is former filtering flow area, speed will be reduced to
78.36%.Certain existing type filter flow faces average speed is about 5m/s, then newly designs filter flow faces average speed
For 3.918m/s, sand and dust filter efficiency will improve about 16%, and ventilation resistance will reduce about 67Pa.
