Description
Technical field
The utility model relates to the powder material comprehensive process industry pressure equalizing devices such as a kind of fly ash, cement, slag micropowder, particularly relates to a kind of storehouse top stable equilibrium device.
Background technology
Coal dust is combustible material, and Class B fire dangerous material, dust has firing property.When coal dust reaches finite concentration in atmosphere, set off an explosion under the effect of external high temperature, collision, friction, vibration, naked light, electro spark, the blast produced after blast can make the dust from flying of deposition, causes subsequent explosion accident.Based on this characteristic of coal dust, Pulverized Coal Bin should transfer out warehouse-in by unreactable gas (as nitrogen, carbon dioxide gas etc.), and top, storehouse is provided with explosion-proof dusting equipment and breathing valve.Explosion-proof dusting equipment generally adopts explosion proof type bag collector, supporting centrifugal blower.Dusty gas enters from bag collector entrance, and through sock filtration, dust granules falls into dust-precipitator and returns ash bucket, and gas is extracted out by centrifugal blower, if the gas extracted out is discharged in air, can cause the wasting of resources; If the gas extracted out enters in storage vault again, when forming negative pressure in the pipeline of the moment that centrifugal blower is closed in connecting fan and large storehouse, the dust in storehouse can be sucked in centrifugal blower by negative pressure, causes certain influence even can damage blower fan to the performance of centrifugal blower.
The pressure act as inside and outside balance storehouse of breathing valve, Ruo Kunei is in malleation or high negative pressure state, can impact, particularly steel silo to the stability of storehouse wall construction, in addition in storehouse, malleation can cause emitting grey phenomenon to occur, and therefore needs to arrange breathing valve to reduce the pressure reduction inside and outside storehouse on top, storehouse.Conventional breathing valve backs down a hole, and rainproof cover is arranged in hole.For Pulverized Coal Bin, common breathing valve makes large storehouse directly be communicated with air, if coal dust dust enters air from breathing valve, then can set off an explosion under the effect of high temperature, collision, friction, vibration, naked light, electro spark.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of storehouse top stable equilibrium device of new structure, make it have more value in industry.
