Description
Technical field
The present invention relates to filter technology fields, and in particular to a kind of adaptive fabric filter of joint backwash
Background technique
Fabric filter is its tool of rotor type fibre filtrate using rotor type fibre filtrate as the Series Filter of technological core
Have the advantages that high granule filter material backwash wash degree, backwash and initial filter water water consumption are few；There is fibre filtering material specific surface area again
Greatly, the advantage that filtering accuracy is high, holding filth capacity is big, void ratio is high；Also with adapting to, different medium ability is strong, backwashes simultaneously
The feature that effect is good, filter bed utilization rate is big.When filtering, rotor type fibre filtering material forms hole in filter and is from top to bottom in
The filter bed of the near ideal of up big and down small change of gradient distribution, the structure of filter bed are conducive to effective point of solid suspension in water
From big solid suspension will be trapped on top, and the small solid suspension for failing to be trapped is by downlink, due to filter bed
Gap gradually becomes smaller, and will be trapped in lower part.Filter bed to be formed in filter by rotor type fibre filtering material not only has
There is the high-precision of filtering, while also there is the high filtering velocity of filtering.Filter backwash when, water flow, air-flow brute force attack under, filter
Bed expansion, filtrate float, and fibre bundle is gradually in bulked state, since rotor type fibre filtering material is with rotor, rotor band
Kinetodesma tow makees insufficient rotation, waves, and mutually impacts, to greatly speed up the suspension adhered on fibre bundle
The separation of grain, improves the cleaning speed of filtrate, has saved the water consumption of backwash, has saved the energy of backwash.
The fabric filter of the prior art, which requires to adopt, to be configured additional hydraulic system and driving device and carried out to liquid
Filter and backwash result in the manufacturing cost for leading to fabric filter high in this way, and energy consumption is high, and maintenance is more difficult, poor reliability.
