Description
Technical field
The present invention relates to a kind of sludge dehydration device, specifically, it relates to a kind of is the sludge dehydration device of core component with plum blossom tubular membrane element, and it can dewater to the mud that various wastewater produces.
Background technology
In sewage disposal process, can separate and produce a large amount of mud, these moisture percentage in sewage sludge are higher, are flowable state, and the subsequent treatment difficulty is very big, and the processing of mud and disposal for ease needs mud is dewatered.The sludge dewatering expense accounts for 15% of total disposal cost, and therefore, the energy consumption that reduces sludge dewatering is very crucial.Device for dehydrating sladge waste commonly used at present mainly contains rolling-type sludge dewatering equipment, belt filter pressing dehydrator, plate compression dewaterer and traditional extrusion equipment.The structure of the dewaterer that these are known is all very complicated, and volume is bigger, and energy consumption is higher, increases the cost of sludge dewatering.Simultaneously, the mud extraction of these equipment is discontinuous, also can make the waste sludge of living face produce capillarity sometimes.
Patent No. CN1666965A discloses a kind of waste sludge dewater unit, through knot cake processing mode the on-the-spot various waste sludges that produce of industry is carried out processed, and the advantage of this device is mud extraction continuously, and shortcoming is a complex structure, and energy consumption is higher.
Summary of the invention
The objective of the invention is to, a kind of sludge dehydration device that can solve the prior art problem is provided.
For realizing above-mentioned purpose; The present invention includes dewaterer body and bubbling device two parts; Wherein the dewaterer body comprises stoste import, filter core, filtrate pipe, collector tube, drain pipe, stoste outlet, filtered solid outlet, overfall, and bubbling device is made up of blowing pipe, valve, hydraulic pump and filtrate tank.
In the described dewaterer body, stoste import and stoste outlet lay respectively at the dewaterer two bottom sides; Filter core adopts plum blossom tubular type separating film element, and a plurality of filter cores are arranged and form dewater unit, and each row filter core top connects a filtrate pipe, and all filtrate pipes connect collector tube in the same side, and collector tube connects drain pipe.One side is provided with overflow pipe on dewaterer top, and the top connects bubbling device through blowing pipe.Filtrate (liquid is established on the dewaterer right side, and filtrate (liquid connects bubbling device.The dewaterer bottom is a filtered solid outlet.
The said plum blossom tubular type separating film element that is used for filter core comprises outlet pipe, plum blossom chimney filter, filter cloth, filter cloth snap ring, filter pocket, base.The plum blossom chimney filter is that the center is the plum blossom shape and is distributed in around it with the outlet pipe, and plum blossom chimney filter quantity is 4 or 6, and is very close to each other between the plum blossom chimney filter, is welded on the outlet pipe; On the plum blossom chimney filter filter pocket is arranged, each filter pocket width is 3-5mm, and length is 4/5ths of plum blossom chimney filter length, and spacing is 2-4mm between the filter pocket; Filter cloth wraps in the plum blossom chimney filter outside, covers the plum blossom chimney filter fully, and the monoblock filter cloth is fixed through two filter cloth snap rings up and down; Whole membrane component supports through the cup dolly of hollow, and said base and plum blossom chimney filter connect together through welding.
Described bubbling device is divided into air purge and liquid is washed, and wherein air purge is divided into again along washing and back washing.
The liquid part of touching of the present invention is not used metal fully, has outstanding Corrosion Protection for strongly corrosion liquid, metal mixture etc.The material of dewaterer body interior is in the resin interlining, and the material of filter core can be selected from PP, PPS, PVDF, Teflon as required, thereby avoids the metal erosion problem.
Sludge dehydration device of the present invention, the cleaning of the drying of filtration back filter cake, discharge, filter cloth etc. can fully automatic operation.Owing to do not have drive unit, simple in structure, so can tackle the bigger situation of filter area.In addition, adopt seal tube, realized leak free stable dewatering and filtering for the very important sealing of filter.

The specific embodiment
For realizing above-mentioned purpose; The present invention includes dewaterer body 1 and bubbling device 2 two parts; Wherein dewaterer body 1 comprises stoste import 11, filter core 12, filtrate pipe 13, collector tube 14, filtrate (liquid 15, filtered solid outlet 16, stoste outlet 17, overfall 18, blowing pipe 19, and bubbling device 2 is made up of valve 21, valve 22, valve 23, filter pump 24 and filtrate tank 25.
Stoste is pressed into through stoste import 11 carries out filtering means dehydration in the dewaterer body 1.Filtrating arrives filtrate pipe 13 through filter core 12, is collected together by collector tube 14 then, finally under the suction of filter pump 25, is recovered in the filtrate tank 26 through filtrate (liquid 15.When the stoste in the dewaterer body 1 is excessive, return former liquid bath through overfall 18.
When utilizing compressed air to clean, at first valve 22 is opened automatically, utilizes purge gas to push back former liquid bath to stoste through stoste outlet 17, when stoste is removed when clean; Valve 22 is closed automatically, and valve 21 is opened automatically then, makes attached to the drying of ventilating of the filter cake on the filter core 12; Behind filtration cakes torrefaction, pressure increases in the dewaterer, and valve 21 is closed automatically; Valve 22 is opened, and through purge gas the solid, shaped filter cake is come off from filter core 12, when filter cake comes off fully; Pressure reduces in the dewaterer, and valve 22 is closed automatically, and filter cake is discharged from the filtered solid outlet 15 of dewaterer body 1 bottom and reclaimed.
When utilizing the clear water back washing, the same compressed air that passes through earlier is the stoste emptying in the dewaterer body 1, and valve 23 is opened automatically then, feeds back washing water, and filter cake is reclaimed with the slurries shape.
