Description
Technical field
The present invention relates to a kind of filter, be specifically related to a kind of high efficiency particulate air filter, belong to gas analysis field.
Background technology
In the industries such as petrochemical industry, iron and steel, papermaking, network center, control room, cabinet room etc. maintain various scene and set
Standby is properly functioning, and the control equipment undertaking various control task in a large number has also been concentrated in its indoor, equipment in longtime running, its
Internal semiconductor devices is as easy as rolling off a log to be corroded, and there is hydrogen sulfide, carbon dichloride, sulfide, nitride in air unavoidably
Deng corrosive substance.In prior art, generally dust in air and corrosive substance are filtered respectively, this filter type
Not only used device is many, and filter effect also difficulty reaches the standard required by specification.In weight dirts such as petrochemical industry, iron and steel, papermaking
Dye industry, practitioner, often in contaminated air, adversely affects healthy, and its workshop produces
Waste gas is also required to process.In gas analysis industry, when gas is detected, certain owing to often containing in tested gas
The dust of amount and impurity, so sample gas is before entering sensor, the most all first pass through filter, and filter uses long, just
Can assemble substantial amounts of dust and impurity on filter course, result in blockage filter, affects the degree of accuracy of sensor, causes measuring knot
Fruit produces error, needs regular dismounting cleaning filter filter, uses inconvenience.At present, the core original paper of filter
Being to consider layer, it is glass fibre or polyester fiber that the material of filter course uses, although the filtering layer of this technical scheme can be well
Solve filtration problem, but owing to the material of various filter courses is consistent, when needing the fluid filtered to pass through, passing through of each filter course
Gap is fixing, it is impossible to playing and become the effect that gap filters, there is also impurity simultaneously and be not fixed easily absorption, filtering accuracy is the highest
Defect, needs further to improve.
Summary of the invention
The technical problem to be solved is, the shortcoming overcoming prior art, it is provided that a kind of high efficiency particulate air filter, this mistake
Filter constructions is simple, and modulability is strong, easy to use, can remove the impurity in gas, pernicious gas, moisture, dust etc., multilayer mistake
Filtering layer physical filtering and chemical filtering combine and improve the precision of filtration, can regulate filter course according to the actual conditions of gas,
Playing the filter effect of optimum and be carried out filter course easy to maintenance, this high efficiency particulate air filter is easy to mobile, reduces work strong
Degree, the anticorrosive property of high efficiency particulate air filter extends by force service life, reduces cost.
In order to solve above technical problem, the present invention provides a kind of high efficiency particulate air filter, including filter housings, filter course,
Air inlet pipe and escape pipe, filter course is arranged in filter head housings body, and air inlet pipe and escape pipe are separately positioned on filter housings
Both sides, wherein:
Filter housings is the rectangular structure of hollow, and filter housings upper surface is along the width of filter housings
Having four through holes, through hole is parallel setting between rectangular through holes through hole；
One end of filter course is provided with the fixed plate perpendicular with filter course, and filter course is placed in filter head housings by fixed plate
Internal, fixed plate is made up of the groove extended on base plate and base plate, groove and the suitable guarantee of through hole on filter housings
Groove is just placed in through hole, and groove fits tightly with through hole surrounding, and filter course is fixedly connected in groove, and the surface of base plate sets
With handles；
Filter course is made up of the first filter course, the second filter course, the 3rd filter course and the 4th filter course, and first filters
Layer, the second filter course, the 3rd filter course and the 4th filter course are respectively arranged in through hole by fixed plate, heap in the first filter course
Being filled with activated carbon, the second filter course is non-woven fabrics stacked structure, and the aperture of non-woven fabrics is in 30-40 μm, and third layer filter course is for changing
Learning filter course, the 4th filter course is composite fibre filter course.
The technical scheme that the present invention limits further is:
In aforementioned high efficiency particulate air filter, the threaded bend pipe of import department of air inlet pipe, the openend of bend pipe is horn-like knot
Structure.
The opening part of air inlet pipe is threaded a bend pipe, uses bend pipe can filter dust according to actual conditions swivel elbow
Some impurity gas being badly in need of filtering such as at big place, poisonous gas leakage more, and the opening of bend pipe is horn-like structure, increases
Big contact surface, improves the efficiency filtered.
In aforementioned high efficiency particulate air filter, the width of through hole is equal with the width of filter housings, it is ensured that be arranged in fixed plate
Filter course reduce filter course when being placed in filter head housings body through through hole can be with the space of filter housings inwall, it is ensured that filter
Effect.
In aforementioned high efficiency particulate air filter, activated carbon is cocoanut active charcoal, uses activated carbon landfill the first filter course, removes gas
The impurity that middle particle is bigger, reaches effect that primary filter processes, it also avoid larger particles impurity filter by suction simultaneously and make
The infringement of filter in pairs, it is ensured that in the properly functioning and service life of prolongation filter of work, reduce cost.
In aforementioned high efficiency particulate air filter, the bottom of filter housings is fixedly connected with road wheel by folding rod.
The convenient carrying the most in time of road wheel comes, it is not necessary to personnel take efforts carrying, when filter works
Energy limit working edge is moved through the position of filter.
In aforementioned high efficiency particulate air filter, folding rod is by fixing bar and motion bar forms, and described motion bar is bolted even
Being connected on the lower end of fixing bar, the upper end of described fixing bar is fixedly connected on the bottom of filter housings, fixing on described motion bar
Road wheel described in connection.
Folding rod can put down road wheel and transport specially place when filter uses, and when need not use, upwards rolls over
Stack road wheel, be placed on one side, convenient transportation, firm effect can be reached.
In aforementioned high efficiency particulate air filter, the surface spraying of filter housings has the anticorrosive coat of 8-10mm, and anticorrosive coat is clinkering ring
Oxygen powder or three-layer polyethylene, the environment of filter work is arduouser, at high humidity, works in the environment of pernicious gas is many
Time, filter surfaces is because the reason of humidity and pernicious gas can accelerate corrosion and oxidation so that the surface thickness of filter by
Gradual change is thin, filter shortening in service life, changes filter ordinary, increases cost, and the comparison at filter sprays 8-10mm's
Anticorrosive coat can extend the service life of filter, expands filter applicability, can use in more environment.
In aforementioned high efficiency particulate air filter, chemical filtering layer is highly acidic cation fiber or weakly-basic anion fiber composition；
Composite fibre filter course is made up of two-layer netted Polyester Fibers layer and one layer of blend fibre layer, and blend fibre layer is arranged at two
Between reticulated polyester fibrage；Use composite fibre filter course can solve to become sedimentation and the suction of the purpose that gap filters, beneficially impurity
Attached, improve filtering accuracy.
The invention has the beneficial effects as follows:
Present configuration is simple, and convenient transportation preferably can carry out filtration, purification to gas, and that can remove in gas is various
Harmful substance or harmful components, filtering accuracy is high, effective, and can reach according to the pollution condition of gas transformed filtering layer position
To optimum filter effect, modulability is strong.
