For addressing the above problem, the utility model provides a kind of ceramic membrane recoiling device, and this ceramic membrane recoiling device comprises air compressor machine and the air intake valve that communicates with air compressor machine and ceramic membrane.
Alternatively, this recoiling device also comprises pressure maintaining valve, and it is that air intake valve is communicated with the outlet of pressure maintaining valve that said air intake valve communicates with air compressor machine, and the import of pressure maintaining valve is communicated with air compressor machine.
The utility model also provides a kind of ceramic membrane equipment, and this ceramic membrane equipment comprises ceramic membrane, air compressor machine and air intake valve, and said air compressor machine is communicated with air intake valve, and said air intake valve is fixed on the ceramic film body and with said ceramic membrane and communicates.
Alternatively, also comprise pressure maintaining valve, it is that air compressor machine is communicated with the import of pressure maintaining valve that said air compressor machine is communicated with valve, and the outlet of said pressure maintaining valve is communicated with air intake valve.
Alternatively, this ceramic membrane equipment also comprises air inlet pipe, and it is that the outlet of pressure maintaining valve is communicated with an end of air inlet pipe that the outlet of said pressure maintaining valve is communicated with air intake valve, and the other end of air inlet pipe is communicated with air intake valve.
Alternatively, said air intake valve has two, and said ceramic film body and ceramic membrane also have two, and said air intake valve is fixed on the ceramic film body and communicates with said ceramic membrane is that each air intake valve is fixed on the ceramic film body and with a ceramic membrane and is connected.
Compared with prior art, the utlity model has following advantage:
The utility model communicates with ceramic membrane through air intake valve, and air compressor machine is set, so, at the film run duration, utilize compressed air to remove the material that is blocked in the ceramic membrane micropore; Prolong the cleaning frequency, improve flux, reach the purpose of enhancing productivity, and, on wholesomeness; The gas that recoil is used is completely without oily air compressor machine compressed and supplied air, can not produce feed liquid and pollute, and more can not produce waste water, can not produce the wastewater treatment burden; Further, on convenience, aborning, in the of short duration shutdown of ceramic membrane; Start air compressor machine, just can accomplish recoil within three minutes, after the air-flow recoil, the flux of ceramic membrane significantly increases.
