Description
Technical field
The invention belongs to technical field of sludge treatment, be specifically related to a kind of no filter-fabric vertical compression sludge high-pressure water extracter.
Background technology
The mud that sewage work produces, conventionally account for 0.5% to 1% of sewage total amount, be accompanied by the increase of sewage quantity, the sludge quantity that sewage disposal produces also increases thereupon, expect national sewage load in 2015 and will reach 55,000,000,000 tons, 3,500 ten thousand tons of dewatered sludge generations.Growing with each passing day of current Chinese sludge creation amount seriously falls behind and forms sharp-pointed contradiction with processing power wretched insufficiency, processing means, and a large amount of wet mud is arbitrarily transported outward, simply landfill or stacking, causes many cities to become " mud besieged city ".For this situation, develop advanced deeply dehydrating sludge technology extremely urgent.
Sludge dewatering is an important link of whole sludge treatment technique, its objective is and makes solid enrichment, reduces sludge volume, for the ultimate disposal of mud creates conditions.For mud liquid phase is separated with solid phase, must overcome the bonding force between them, so the subject matter that sludge dewatering runs into is energy problem.Multi-form for bonding force, the different extraneous measure of autotelic employing can obtain different dehydrating effects.Sludge dewatering and mummification comprise natural-dehydration, mechanical dehydration and several modes of thermal treatment mummification.Time of natural-dehydration is long, efficiency is low, and place resource occupation is serious; The energy consumption of thermal treatment mummification is serious, high cost; These two kinds of modes are difficult to promote on a large scale.General big-and-middle-sized sewage work of China all adopts mechanical dehydration mode to reduce the water ratio of mud at present.
Mechanical sludge dewatering is take porous material as dehydration medium, using dehydration medium both sides pressure difference as impellent, moisture in mud is forced through dehydration medium, form with filtrate is discharged, solid particulate is trapped within on dehydration medium, become the filter cake (sometimes claiming mud cake) after dehydration, thereby realize the object of sludge dewatering.The method of conventional mechanical sludge dewatering has following three kinds:
(1) vacuum hydro-extraction: press mode (vacuumizing) that moisture in mud is got rid of by pair.
(2) centrifuge dehydration: moisture in mud is got rid of by centrifugal force.
(3) filter-press dehydration: by mechanical presses mode, moisture in mud is extruded, filter-press dehydration includes again belt type filter-pressing dehydration plant, Die Shi filter-press dehydration and filter press dehydration.
The water ratio height of dewatered sludge is relevant with sludge quality and dewatering Principle; Generally, the moisture content of the cake of vacuum hydro-extraction is 70-80%, and centrifuge dehydration is 80-85%; In filter-press dehydration, the moisture content of the cake of belt type filter-pressing dehydration plant is that the moisture content of the cake of 80-85%, Die Shi filter-press dehydration is 80-85%; The moisture content of the cake of filter press dehydration is 50-80%.
Before within 2012, national regulation Sludge landfill is disposed, water ratio must be down to below 60%, and before burning disposal, water ratio must be down to below 50%; Visible sludge vacuum dehydration, centrifuge dehydration all do not reach landfill and burn the requirement to moisture percentage in sewage sludge; Although the filter press water extracter dehydrated sludge cake water ratio in filter-press dehydration can reach 50% sometimes, but effect is unstable, and can not automatic discharging in work, need to drop into a large amount of human assistances and carry out mud cake cleaning, filter cloth needs often cleaning, changes, and running cost is higher, and level of automation is very low, complicated operation, inefficiency.
