Description

Dynamic core bag filters desludging device

Technical field

The utility model relates to sludge filtrating technology fields, and in particular to a kind of dynamic core bag filtering desludging device.

Background technique

It looks back China's fixed-end forces industry, especially urban wastewater treatment firm primary sludge and biochemistry pool excess sludge is handled The state of development of disposition, may be summarized to be: starting evening, development are fast.Basic handling technology are as follows: concentration basin, dehydration (sheet frame, belt Deng), the dry, carbonization of blade etc..As environmentally friendly system is more and more perfect, it is desirable that be increasingly stringenter and living standards of the people It is continuously improved, environmental consciousness is more and more stronger, us certainly will be required to find new technical point and broken through.

Water environment pollution and shortage of water resources are the two large problems that the whole world is faced with.Currently, China's total amount of sewage discharge is 395 × 108m3, for root it was predicted that the year two thousand fifty, China's total amount of sewage discharge is up to 1200 × 108m3.It is attached to and can produce simultaneously The primary sludge and biochemistry pool excess sludge of raw 12 × 108t.If sludge cannot be dealt carefully with, polluter meeting again It is re-released into ambient enviroment, ambient enviroment is caused seriously to pollute.While sewage treatment realize sludge minimizing, Stabilize, innoxious and recycling, realize the benign cycle of water and the sustainable use of water resource, be we now there is an urgent need to It solves the problems, such as.

Utility model content

In order to solve the above-mentioned technical problem the deficiency in, the purpose of this utility model is that: a kind of dynamic core bag mistake is provided Desludging device is filtered, benign water circulation is can be realized, sludge is effectively handled, is also not easy to block the filtering of dynamic core bag Device.

The technical scheme adopted by the utility model for solving the technical problem is:

The dynamic core bag filters desludging device, including shell, and the lower part of shell is arranged sludge pipe, row is arranged on sludge pipe Enters mud pipe is arranged in slurry valve, the side of lower part of the housing, and high-pressure hydraulic pump is arranged in enters mud pipe, and the inside setting dynamic core bag of shell filters Backwash tube is arranged in the upper end of device, shell, and the lower end of backwash tube is linked into dynamic core bag type filter, on the backwash tube Backwashing pump is set, and hot air pipe, outlet tube and circulation pipe, the external blowing hot wind of hot air pipe is respectively set in the side of shell The Single port of machine, circulation pipe is connected with the inside of dynamic core bag type filter, and another port is linked into dynamic core bag type filter Circulating pump is arranged on circulation pipe in outside, is also connected with sewage pipe in enters mud pipe, the sewage pipe connect high-pressure hydraulic pump and shell it Between pipeline on, blowdown valve is set on sewage pipe.

In use, the primary sludge of moisture content 99.2-99.6% and biochemistry pool excess sludge (hereinafter referred to as biochemical sludge) It is squeezed into dynamic core bag type filter by high-pressure hydraulic pump first, biochemical sludge is in fluidized state in dynamic core bag type filter, Using the special construction of dynamic core bag type filter, filter sludge while, also carries out dehydration compression to sludge, according to requirement of engineering, The filtered moisture percentage in sewage sludge of dynamic core bag type filter can be down to 60%.After biochemical sludge stops entering, dynamic core bag mistake Filter self-loopa automatically turns on, by the continuous circulating filtration of circulating pump, by the filtrate in shell on the outside of dynamic core bag type filter It is transported in dynamic core bag type filter and filters again, until stop after biochemical sludge whole filtering and concentrating to specified requirement, meanwhile, Liquid valve is opened, filtrate is discharged by outlet tube.Then hot hair dryer is opened by filter cake stripping, and (moisture content reaches design to be wanted filter cake The sludge asked) it is discharged by sludge pipe, it is transported to other treatment process outside.With the continuous operation of dynamic core bag type filter, strainer meeting It is constantly stifled by the dirt of biochemical sludge, it needs to backwash dynamic core bag type filter after reaching a certain level.It opens Backwashing pump squeezes into clear water opposite direction in dynamic core bag type filter, filter under the action of water flow, in dynamic core bag type filter The automatic diffusion of net is opened, and cleaning is more thorough, will not have any impact to dynamic core bag type filter, opens blowdown valve, recoil Wash water is discharged by sewage pipe, is handled into sewage treatment plant.

Further preferably, dynamic core bag type filter includes the mounting rack of upper and lower two sides distribution, is inserted between upper and lower mounting rack Multiple groups support frame is arranged strainer between support frame, has certain elasticity between strainer and support frame, can be reversed flushing.

Further preferably, liquid valve is set on the outlet tube.

Further preferably, support frame is in triangular prism shaped.

Compared with prior art, the utility model has the following beneficial effects:

The utility model has not only saved the auxiliary facilities such as concentration basin, dewaterer, dehydration machine room, and occupied area it is small, Operating cost is low, system is stable, Automatic Control, and the special construction of dynamic core bag type filter makes filtering reduce dirty stifled wind Danger, improves service life.The utility model integrates sludge condensation, sludge dewatering, the main table of excellent process performance Now in:

1) occupied area is small, saves the auxiliary facilities such as sludge concentration tank, dehydration machine room, dewaterer.

2) system run all right, according to different engine requests biochemical sludge can be filtered to required value (moisture content >= 60%).

3) the special construction of dynamic core bag type filter makes dynamic core bag type filter reduce dirty stifled risk when running, mentions High service life.

4) this technology does not need to add the medicaments such as PAC, PAM, can save operating cost.
