Embodiment
By reference to the accompanying drawings the application is described in further detail below by embodiment.
Embodiment one
Please refer to Fig. 1, present embodiments provide one and prevent releasing the dense dry systems of phosphorus sludge, comprise sludge thickening tower 10 and chamber-type press filter 20
Sludge thickening tower 10 is for carrying out concentrating and precipitating to the mud sent into.
Chamber-type press filter 20 is communicated with sludge thickening tower 10, dewaters for the thickened sludge sent into sludge thickening tower 10.
What the present embodiment provided anti-ly releases the dense dry systems of phosphorus sludge, first adopts sludge thickening tower to carry out concentrating and precipitating to the mud sent into, adopts chamber-type press filter to dewater to the thickened sludge that sludge thickening tower is sent into afterwards again, can reduce the water ratio after sludge treatment.After to the sludge drying after process, can be used as fuel and use, avoid Sludge landfill to cause secondary pollution.Therefore, this prevents that releasing the dense dry systems of phosphorus sludge has good economic benefit and environmental benefit.
In a particular embodiment, prevent that releasing the dense dry systems of phosphorus sludge also comprises the pressure sludge tank 30 be arranged between sludge thickening tower 10 and chamber-type press filter 20, for the thickened sludge press-in chamber-type press filter 20 sent into by sludge thickening tower 10.The mud that pressure sludge tank 30 can be sent into sludge thickening tower 10 plays the effect of buffering.Concrete, as shown in Figure 1, pressure sludge tank 30 can by extraneous pressurized air by the mud press-in chamber-type press filter 20 in pressure sludge tank 30.
Anti-release the dense dry systems of phosphorus sludge and also comprise the pneumatic diaphragm pump 40 be arranged between sludge thickening tower 10 and pressure sludge tank 30, for by the thickened sludge pump-in pressure sludge tank 30 in upgrading tower 10.Use pneumatic diaphragm pump 40 can adapt to the particular surroundings of sludge treatment well, ensure that mud sends into pressure sludge tank 30 from sludge thickening tower 10 smoothly.
