Description
Technical field
The utility model relates to sewage treatment field more particularly to a kind of online frequency modulation on pulse film surface automatically cleaning dresses of ceramic membrane
It sets.
Background technique
Currently, be an important option of water treatment technology using ceramic film process sewage, but ceramic membrane uses one section
After will be contaminated and even block, and dirt is difficult to wash in film, needs in use so as to cause ceramic membrane
Frequently backwash, and also to use medicament specially to be cleaned within a very short time, also therefore lead to ceramic membrane service life
Short, fluctuation of service, operating cost are high.
Utility model content
The purpose of this utility model is to provide a kind of online frequency modulation on pulse film surface cleaning apparatus for self of ceramic membrane, existing to solve
The problem of with the presence of technology.
The utility model uses following technical scheme:
A kind of online frequency modulation on pulse film surface cleaning apparatus for self of ceramic membrane, including ceramic film component 3, ceramic film component 3 include
Ceramic membrane 2 inside shell 7 and shell 7, the lower part of shell 7 are provided with water inlet, and water inlet connects sewage by sewage conduct
Source 8 is provided with circulating pump 1 on sewage conduct；The top of shell 7 is provided with water outlet, sets on the outlet conduit outside water outlet
It is equipped with and manually adjusts pump 6；Water purification outlet 10 is provided on the side wall of shell 7；
It further include the pneumatic diaphragm pump 4 being arranged in parallel with the circulating pump 1, pneumatic diaphragm pump 4 connects gas source by pipeline
9。
The gas source 9 also passes through the air inlet of 7 bottom of pipeline connected with outer casing.
The gas source 9 connects the air inlet on pneumatic diaphragm pump 4 and shell 7 by Pneumatic valve 5.
The utility model has the beneficial effects that the utility model can operate normally purification sewage in ceramic film water treatment equipment
In the state of effectively clean film surface pollution of the ceramic membrane in water process, reduce the backwash frequency of ceramic film water treatment equipment,
Greatly extend film surface cleaning frequency and ceramic membrane service life.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The utility model provides a kind of online frequency modulation on pulse film surface cleaning apparatus for self of ceramic membrane, including ceramic film component 3, should
Ceramic film component 3 is the prior art, and ceramic film component 3 includes shell 7, is equipped with poroid ceramic membrane 2, shell 7 inside shell 7
Lower part with wastewater inlet, top with concentrated water export, side have water purification outlet 10, ceramic film component can to sewage into
After row purification, water purification and concentrated water are discharged.
The wastewater inlet of shell connects source of sewage 8 by sewage conduct, connects on sewage conduct and sewage is pumped into shell 7
The circulating pump 1 that portion is purified, and manual modulation valve 6 is connected on the concentrated water water outlet external pipe of shell upper, sewage passes through
The pressurization of circulating pump 1 is squeezed into ceramic film component 3, and after the inner hole for flowing through ceramic membrane 2, water purification is discharged from water purification outlet, and concentrated water is from dense
Water out discharge, and the manual modulation valve 6 being arranged on concentrated water pipeline, can be by manually adjusting aperture, by adjusting manual
The opening degree size of regulating valve 6 can make sewage have different pressure inside ceramic film component, and then can make water purification
Pass through the outer wall output of ceramic membrane.After ceramic film component work long hours, dirt will not be gone out by concentrated water outlet drain completely,
Can be in ceramic membrane encrustation, the time dirt of longer accumulation is more, thus under keeping ceramic membrane blocking water yield serious.
Therefore, the utility model is being arranged in parallel setting pneumatic diaphragm pump 4 on pipeline with circulating pump 1, and pneumatic diaphragm pump 4 is logical
Piping connects gas source 9.Pneumatic diaphragm pump 4 is that one kind using compressed air causes volume as power, by pump interior diaphragm reciprocal transformation
The positive displacement pump of variation, working principle is similar to plunger pump, therefore pneumatic diaphragm pump is different from electrodynamic pump, and electrodynamic pump water outlet is even
What speed was uninterruptedly discharged, and pneumatic diaphragm pump 4 can move reciprocatingly with the variation of compressed air tolerance size, so that dirty
The water that water enters in shell is periodic breaks, that is, exporting one one water flow into shell, hydraulic pressure is
Pulse wave.
After pneumatic diaphragm pump 4 is in parallel with circulating pump 1, pneumatic diaphragm pump 4 is made by the size that control gas source exports tolerance
Alternately water supply frequency is pressed, so that generating water into the sewage in ceramic film component shell 7 in the state of 1 normal water supply of circulating pump
The pulse of stream, hydraulic pressure, and then continuous stream impulse is formed in ceramic membrane inner hole, strengthen the pottery of cross-flow filtration by pulse water flow
Porcelain film film surface pollution object pre-washing function realizes that film surface automatically cleaning extends the fouling membrane period, to obtain optimal film surface cleaning effect
Fruit more effectively removes the dirt in membrane tube.
In actual use, can by change circulating pump 1 parameter, the parameter of pneumatic diaphragm pump 4 make water flow and
The variation of tolerance generating period realizes the adjustment of pulse frequency width, normal cross-flow filtration technique is made to become frequency modulation on pulse cross-flow work
Skill forms continual stream impulse in film inner hole, more effectively removes the dirt in membrane tube.
The utility model gas source 9 also passes through the air inlet of 7 bottom of pipeline connected with outer casing, and gas source 9 is connected by Pneumatic valve 5
Air inlet on pneumatic diaphragm pump 4 and shell 7.It is mixed to can be used for carrying out the sludge settling of shell interior bottom portion gas, prevents sludge
It is deposited in outer casing bottom accumulation, while outer casing bottom can also be open, for sludge settling of the gas after mixed to be discharged to the outside, prevented
Accumulate inside the shell, and the mixed rear excessive sludge fouling on ceramic membrane of gas can be prevented.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model.
