Description
Technical field
The utility model belongs to production and processing workshop filtering technique application field, more particularly to a kind of metallic dust filtering
Device.
Background technology
Battery explosion reason on fire is varied, but the explosion caused by most common or dust and metallic particles.
All there are one common explosion causes for they, that is, the internal short-circuit caused by dust or metallic particles, and then cause electricity
The inside drastic discharge in pond and energy accumulation, so as to cause the on fire from explosion of battery.Battery explosion caused economic damage on fire
The personnel that become estranged injury can not be estimated.Therefore, in the production process of entire battery, the dust degree in workshop must be controlled one
In fixed range, and the dry wind ventilation opening in workshop is exactly the important sources of metallic dust.If dry wind ventilation can be controlled
The dust of mouth can substantially reduce the dust degree in battery production workshop, reduce the accident rate occurred in cell production process.
Dust has certain energy as other substances.Since the grain size of dust is small, surface area is big, to its surface energy
Also increase.Its surface area of the coal of one piece of 1 g weight only has 5~6c ㎡, and the coal dust floating dust of 1 g, and surface area is up to 2 ㎡.Dust
It is mixed with air, flammable mixed gas can be formed, if meeting open fire or high temp objects, easily caught fire, completed between momentariness burned
Journey discharges a large amount of thermal energy, burning gases is made to increase suddenly, and volume fiercely expands, and forms the very high bulbs of pressure.Existing dedusting
Mode is mainly filter cartridge type dedusting and filter bag type dedusting, and filter cartridge type dedusting is because cartridge surface is V-arrangement gauffer, so compressed air exists
Repeatedly when deashing gauffer point go out it is easy to wear.V-arrangement gauffer space is small and dust can be caused easily to remain or be deposited in blocking filter at V-arrangement
Cylinder increases filtration resistance, to make filter area reduce, filter core is made to be easier breakage, and the frequency of opposite replacement also will increase,
The reason of because of replacement frequency and filter cylinder price higher, so filtering drum dust removing follow-up maintenance expense is certain to higher.
And relative to cloth-sack-type dust removal, for different type gas, the cloth bag of respective type should be selected, and need often more
Cloth bag is changed, cloth bag consumption is larger.When collecting the high dusty gas of humidity, moist keeping measures should be taken, in order to avoid caused because of moisture condensation "
Paste bag ", therefore bag-type dust gas has the humidity of gas certain requirement.
In industry, the filter that each battery uses is irregular, and the filtering that can not meet metallic dust mostly is wanted
It asks, it is smaller that metallic dust possesses grain size（Diameter about 100nm ~ 500nm）The characteristics of.At home, this kind of of metallic dust can be removed
There is also but there are bulky for equipment（Floor space is about 30 squares）, and the features such as involve great expense, can not answer on a large scale
With, and it is low to the efficiency of dust collection of metallic dust.Such cleaner is equally existed in Japan, South Korea, efficiency of dust collection is opposite
It is higher, but involve great expense.
Present workshop can not effectively filter the metallic dust of dry wind air inlet, and the dust degree in workshop is caused to occupy
It is high not under, many unfavorable factors are produced to the production of battery, be easy to cause the short circuit of battery.
