1. Range

This standard rules the define,type,modal,method for installing, technical requirement, experimental method,inspection method,inspection gulation,Marker,package,shipment,storage of Cartridge Type Dust Collector

This standard is adapt to the design and build of cartridge type dust collectors using air filter cartridge using filter material of Celloluse,Cellulose/Polyester blended Polyester+Menbrane air filter cartridge.

This Standard is not adapt toexplosion-proof type.

2Definition

Below the standard uses defines

2.1 Membrane Filter Media

In filter material surface to paste the duplicate pore membrane to enhance certain performance index the filter material.

2.2 Filter Media Used for Cartridge

After the special handling processing, has the close pore structure also the quality of material toughs it out, can make the multi-pleat circular filter drum, also has certain performance index

filter material.

2.3 Air Filter Cartridge

By the filter cartridge took the filtering element composes the multi-pleats, the circular, the tube shape, match by in the metal or the chemical material support the core filtering element.

2.4 Cartridge Type Dust Collector

By the filter cartridge took the filtering element composes or uses the pulse injection the dust remover.

2.5 Induction The Spray Nozzle

Has many times induction performance, increases the injection quantity, causes when the filter drum clear ash injection pressure, air current even cloth in filter drum endophragm spray nozzle.

2.6 Steel Consumption Quantity

The dust remover main body quality (enters, between discharge flange, arranges above ash mouth flange part, not including support and heat insulating layer, but including must want technological ladder platform equipment quality) and ratio of the filtration area.

2.7 Membrane Fastness

The fastness the membrane adheres to the filter media, indicated by Mpa.

2.8 Burst

Paper or cardboard in unit area along with increases evenly the most tremendous pressure, indicated by Mpa.

2.9 Deflection

Under the standard condition, the curving end clamp stipulation filter paper test specimen to 15° the angle time strength or the moment of force, indicated by mN or mN.m.

2.10 Filter Paper Total Thickness

Filter paper total thickness = filter paper thickness + corrugated thickness

2.11 Corrugated Tthickness

The corrugated shape filter paper corrugated ripple depth, indicated by mm.

2.12 Volatility

Under the stipulation condition, the material which on the filter paper can volatilize (for example

solvent and water and so on) quality, by % expression.

2.13 Resin Content

On the filter paper includes the resin quality, by % expression

3 Iinstallation of Air Filter Cartridge

3.1 the requirement of filter cartridge installation

3.1.1 Vertical installment

3.1.2Filter drum size series and specification

3.2 Filter drum size series and specification

5. inspection rule

5.1 Membrane filter media, filter cartridge and dust collector used in cartridge dust collector must be inspected qualified by manufacturing plant and enclosed with inspection qualified certificate.

5.2 All dust collector parts must be inspected qualified ,and the outsoucing must have qualified certificate.

5.3 Membrane filter media used in filter cartridge,filter cartridge and dust collector examination includes exwork inspection and form inspection.

5.4 Membrane filter media used in filter cartridge’s inspection item according to table15

5.5 Exwork examination

5.5.1 The membrane and filter cartridge used in the cartridge dust collector should be inspected according to table 15,16,15 seperately when exwork inspection

5.5.2 According to other specification examination in ordering agreement stipulation

5.8 Form examination

5.8.1 If there is one of the conditions,membrane filter media and filter cartridge used in cartridge dust collector should have form examination.

5.8.1.1 When Producing for the first time or trial product design finalization

5.8.1.2 When the The stereotypia product structure, the manufacture craft, the material have change greatly, possibly affects the product performance

5.8.1.3 When lot production

5.8.2 The form inspection of Membrane filter media,cartridge and dust collector’s form Cartridge dust collector should be carried on according to table15,16and 15 stipulation.

5.8.3 Form check sample sampling, should extract through in the exwork examination quality products. Each kind of membrana tectoria filter material to extract the test specimen to carry on the pattern examination together every year. each kind of filter drum with the different membrana tectoria to extract one to carry on the form examination every year; The dust remover extracts one every year or in experimenting

scene to extract one to carry on the form examination.

5.8.4 form inspection criterior

5.8.4.1 If in the extraction sample examination project or two basic terms are unqualified, then determines this product is unqualified.

5.8.4.2 If the sample is unqualified, then extracts two to carry on the examination again, if still had one itemt to be unqualified, then determined this batch of products was the defective works, two

samples only then determined completely as the quality products.
