Air-blowing valve, now the pressure in air pressure mud tank enough sludge therein is pressed in filter press, and subsequent air pressure mud tank
In high pressure exhaust gas the effect for playing air blow pressure is also passed in filter press along second pipe, and will be clear in sludge
Liquid is flowed in sump by the 4th pipeline Jing after blow pressure, and the supernatant in clear liquid and sludge concentration tank in sump is equal
Can be excluded by the 3rd pipeline and be recycled, be gone out substantially most water through the sludge of filter press filter pressing
Point, will drop in collecting tank；The 5th pipeline on air pressure mud tank is used for aerofluxuss, and air bleeding valve is opened when aerofluxuss are needed.
A kind of sludge dewatering abatement system and method that the present invention is obtained, which has the technical effect that：
1st, the method that classic screw infusion enters mud mixture is instead of, is operated using air pressure mud tank, reduced because adopting
The expense that screw pump needs to regularly replace the consumable accessory such as stator and produces；
2nd, the forced air injected in air pressure mud tank can subsequently play air blow pressure effect, one-object-many-purposes；
3rd, from the point of view of apparatus, sludge pump does not need high outlet pressure, therefore preparation power substantially reduce；Air compressor machine is
Intermittent operating, reduces energy consumption, and overall power consumption ratio reduces about 12 kilowatts of installed capacitys using the preparation of screw pump, and sets
The standby time for continuously running can shorten -2 hours 1 hour；
4th, pump into air pressure mud tank from mud mixture to start to the process of the casing for filling filter press generally to only need to 30 points
Clock -40 minutes, whole operation period ratio adopts screw pump or common sludge dewatering system will shorten 3 hours or so, and success is real
The requirement for sloughing moisture in sludge of high efficiency, low energy consumption is showed.
