Abstract

The invention relates to a strong pressure type sludge deep dehydration system, belonging to the technical field of environmental geotechnics. The strong pressure type sludge deep dehydration system is composed of a stroke support, a front top plate, a rear top plate, a shrinking steel rod, a piston grouting pump, a discharging plate and more than two arranged dehydrating units; According to the strong pressure type sludge deep dehydration system, the piston grouting pump is adopted to grout under strong pressure, so that a problem that sludge with low moisture content is difficultly fed is solved; the dehydrating units have shrinking functions and can realize sludge deep dehydration under strong pushing action of a hydraulic oil cylinder; the discharging plate can be used for discharging the dehydrated sludge automatically under the cooperative action of the shrinking steel rod and a mechanical arm; the whole system can realize continuous and automatic operation, and the time and labor costs are saved; and the strong pressure type mechanical dehydration mode is adopted, the energy consumption is low, the effect is good, the dehydration treatment cost is reduced and the follow-up sludge disposal way is expanded.

Description

technical field

[0001] The invention relates to a sludge strong pressure deep dewatering system, which belongs to the technical field of environmental geotechnical engineering. Background technique

[0002] With the rapid improvement of my country's sewage treatment capacity, sludge production has increased sharply. Relevant data show that in 2015, the national production of wet sludge (with a moisture content of about 83%) was nearly 40 million tons, with an average annual growth rate of more than 20%. Handling the situation is grim.

[0003] The high moisture content of sludge is a key factor restricting the treatment and disposal of sludge. At present, the equipment used for sludge dewatering in sewage treatment plants in my country includes centrifugal dewatering machines, belt filter press sludge dewatering machines, plate and frame filter press dewaterers and diaphragm plate and frame filter press dewaterers. The dewatering centrifuge has high energy consumption, high...
