Description
Technical field
The invention belongs to separation method field, especially a kind of industrial dust filtration system.
Background technique
Filtration dust catcher is that dusty gas is made to pass through certain filtering material to reach solid dust in separation gas
A kind of high-effective dust-removing equipment.There are two main classes for filtration dust catcher.One kind is the bag using fibrous braid as filter medium
Formula deduster；Another kind of is using gravel bed filter of the particulate matters as filter medium such as sand, gravel, coke.
Sack cleaner is that the materials such as cotton, hair or staple fibre are processed into fabric as filtrate, and filter bag is made to dust-laden
Gas is filtered.When dust-contained airflow is by filtrate hole, dust is got off by detention, and cleaning gas tream is discharged after passing through filter bag.
The dust on filter bag is deposited on by mechanical oscillation, is dropped in ash bucket from filter material surface.
The mesh of filtrate itself is larger, and generally 20~50 μm, the filtrate of surface nappy is 5~10 μm.Therefore, new filter
The efficiency of dust collection of bag is lower.The effects of dust particles are because of sieving, inertial collision, interception, diffusion, electrostatic and gravitational settling, so that
Thick grit generates " bridge formation " phenomenon first by detention between mesh, quickly at the beginning of filter cloth surface forms one layer of so-called dust
Layer.After bonding layer is formed, it has become the main filtration layer of filter bag, and filter cloth only plays to form particle bonding layer and support its
Skeleton function.After dust bonding layer is formed, become filter cloth to all effective filtering material of thick, fine dust, filter efficiency increases severely.
For 1 μm or more of grit, mainly by inertial collision, grit below for 1 μm, mainly by diffusion, total filter efficiency can
Up to 99% or more.With accumulation of the dust on filter bag, efficiency of dust collection is continuously increased, while resistance also increases accordingly.Work as resistance
When reaching a certain level, the pressure difference of filter bag two sides can be attached to some the fine dusts on filtrate and squeeze the past, make to remove
Dirt efficiency is decreased obviously, while dust remover resistance crosses conference and is remarkably decreased the processing gas amount of dust pelletizing system, influences production system
The exhaust effect of system.Therefore, after dust remover resistance reaches certain numerical value, deashing is carried out in time, and cannot be destroyed when deashing
Otherwise dust bonding layer can cause efficiency of dust collection to significantly reduce.
Filtrate of good performance should have that dust containing capacity is big, hygroscopicity is small, high-efficient, resistance is low, long service life, simultaneously also
Should have the advantages that high temperature resistant, wear-resisting, corrosion-resistant, high mechanical strength.The characteristic of filtrate is in addition to related with the property of fiber itself
Outside, also there are much relations with filter material surface structure.The smooth filtrate dust containing capacity in surface is small, and deashing is convenient, is suitable for dust content
Low, tough dust, the rate of filtration used at this time should not be too high.
The filtrate type of sack cleaner is more.Natural fiber, inorfil and synthetic fibers can be divided by filtrate material
Deng；Two class of filter cloth and felt can be divided by filter structure.With the development of the chemical industry, there are many novel filters resistant to high temperature
Material, as aromatic polyamide (nylon and polyamide fibre) can be used for 200 DEG C or so for a long time.Polytetrafluoroethylene (PTFE), polyester fiber (terylene) etc.
The appearance of new material expands the application field of sack cleaner.
However that there are still filter efficiencies is relatively low for filtration system in the prior art, shortage removes harmful organic substance in air
The disadvantages of removing solid capacity.
