PPS Dust Filter Bag Efficient Smoke Filtration Air Filter For
Asphalt Mixing Plant
1. Introduction
Dust filter bag is the key part in the operation of bag filter dust
collector, usually cylindrical filter bag, hanging vertically in
the dust collector, its fabric and design pursuit of
high-efficiency filtration, easy to dust stripping and durable
effect. The selection of dust bag is crucial, directly affecting
the dust removal effect of the dust collector, the selection needs
to take into account the temperature, humidity and chemical nature
of the gas, the size of the particles, the concentration of dust,
the filtration air speed, dust removal method and other factors.
The dust bag has a dust removal efficiency of up to 99.99% and can
effectively separate dust from the flue gas. The life of dust bag
is closely related to the operation status and cost of dust
collector, so it is very important to choose suitable filter
material and design reasonable structure.
Application of dust bag: industrial exhaust gas treatment dust
removal system manufacturer of waste incinerators, coal-fired
boilers, fluidized bed boilers and other flue gas filtration
asphalt concrete mixing, building materials, cement ceramics, lime,
gypsum and other production sites.
2. Classification:
(1) High temperature resistant needle felt
Application: Compared with other filtration materials, the abrasion
resistance, bending resistance and peeling strength of glass fiber
filtration materials are significantly improved. The filtration
speed can reach more than 1.0m/min, and the running resistance is
low. Mace filter material is widely used in iron and steel,
non-ferrous smelting, chemical industry, carbon black, building
materials, electric power and other sectors. Suitable temperature:
below 260.
(2) Glass fiber dust bag
Usage: The filter material has excellent alkali resistance, fully
suitable for filtering alkali flue gas, the filter material is not
subject to corrosion. Suitable temperature: 80-260.
(3) Metas dust bag:
Uses: a special process is used to wrap a dense
polytetrafluoroethylene (ptfe0) protective layer on the surface of
each yarn of the glass fiber filter cloth, so that the filter
material has good resistance to acid and alkali, corrosion, high
temperature, friction and bending resistance, the surface is smooth
and hydrophobic, and the surface of the filter cloth can not be
covered with dust. Use temperature: long-term working temperature
260, short-term temperature 300.
(4) Anti-static dustproof bag:
Use: In general, when the concentration of industrial dust reaches
a certain level, if the electrostatic discharge spark or external
ignition, such as surface dust, coal dust and chemical dust, it is
easy to cause explosions and fires. Suitable temperature: 80-130.
(5) P84 high temperature resistant needle punched filter felt:
Usage: high temperature resistant, can be used for a long time
below 260℃, and has good chemical resistance. It has very
significant filtering effect on dusty gas with acid and alkali
characteristics, which makes it have higher dust removal efficiency
in waste incineration industry.
(6) PPS high temperature resistant dust bag:
Use: With complete strength and internal chemical resistance, it
can maintain good filtration performance in harsh environment and
achieve ideal service life.
(7) Fluoromax dust bag:
Uses: It has the advantages of high temperature resistance, acid
and alkali corrosion resistance, abrasion resistance and bending
resistance. It is easy to remove dust, water and oil repellent. It
can capture high air volume and high concentration of dust. It
overcomes the characteristics of other chemical fiber elongation
and low temperature resistance, and the price is cheaper than other
high temperature resistant filter media. It is suitable for
temperature 80-230.
