Description
[technical field]
The utility model relates to the technical field of dedusting, especially a kind of technical field of bag filter.
[background technique]
The production of calcium zinc organic stabilizer is not related to chemically reacting, and process flow can be divided into 4 steps: raw material weighing, mixing, granulation
And packaging.Raw material weighing is needed according to recipe requirements, and each raw material is poured into stirred tank by different weight proportion.Calcium zinc stabilizer
Raw material be powdery, easily generate fugitive dust in weighing and transmission process, not only will lead to loss of material, it is strong also to will affect worker
Health.
Bag filter is a kind of dry type dust filtration device, and filter bag is using the filter cloth or nonwoven felt of weaving at can
Dusty gas is filtered using the filtration of fabric.The process that bag filter is filtered is divided into two ranks
Section.It is that dusty gas passes through clean filter cloth first, the detention of filter media fibre on the mainly filter cloth of filtration at this time.Its
Secondary is to work as filter bag after a period of use, and due to effects such as sieving, collision, delay, diffusion, electrostatic, filter cloth surface has gathered one
Layer dust, this layer of dust is known as bonding layer, and in motion process hereafter, bonding layer becomes the main filtration layer of filtrate.By bonding layer
Effect, the biggish filter cloth of mesh can also obtain higher filter efficiency.But as dust is in the accumulation of filter cloth surface, cloth
The efficiency and resistance of bag dust collector all can correspondingly increase, and when the pressure difference of filter cloth two sides is very big, some can be attached to
The tiny grit extruding of filter cloth surface is gone down, so that dust collector efficiency declines.In addition, the resistance of bag filter is excessively high also to be made
The air quantity of dust pelletizing system is remarkably decreased, and therefore, it is necessary to timely deashings.The cleaning of existing filter cloth generallys use back flushing type or bastinade
Formula has that ash-removal effect is bad or destroys bonding layer.
[utility model content]
