Abstract
The invention discloses a pulsed tubular membrane. With the adoption of intermittent operation, operations of introducing compressed gas in a pulsed mode and cleaning the membrane surface and membrane pore pollutants as well as automatic control, the system can stably operate for a long time and does not need to be cleaned, the daily cleaning, maintenance and management are simplified, and the operating cost and management cost are reduced. The pulsed tubular membrane can be widely applied to the industries such as chemical industry, metallurgy, foods, medicines, papermaking, printing and dyeing and sewage treatment.
Description
Technical field
The invention belongs to technical field of water treatment, be specially the treater that a kind of solid-liquid (muddy water) is separated.
Background technology
Membrane technique is an emerging high-tech, is also the science and technology of a multi-crossed disciplines.Membrane technique that is ripe and that studying comprises micro-filtration, ultrafiltration, nanofiltration, reverse osmosis, dialysis, kidney machine, electrodialysis, the electrolysis of chlorine industry film, gas delivery, mineral membrane, seepage slope, liquid film, Co ntrolled release, membrane contactor, membrane reactor and microbial film etc. at present.Film and film engineering have entered multiple scientific research and industrial application, are widely used in the fields such as information, the energy, oil, chemical industry, heavy industry, light industry, food, beverage, medical treatment, medicine, military affairs, environmental protection and biotechnology.Promoter action is significantly created to social progress, Economic development, standard of living and environment protection etc.; China also takes much count of membrane technique; the project entering industrial circle increases; however; the membrane science technology of China is compared with Foreign Advanced Lerel; still have larger gap, therefore also have very large development space.
Summary of the invention
Have for hollow-fibre membrane: 1. easily block, need strict pre-filtering.2. cleaning difficulty.3. change film costly, once damage, scrap for whole.4. in fibre pipe, resistance to flow is very large, and the pressure-losses is comparatively large, should not process the shortcomings such as thick liquid, the object of the invention is to the above-mentioned shortcoming can avoiding hollow-fibre membrane.
Described pulsed tubular membrane, comprise be connected with tubular membrane (2) fresh feed pump (1), tensimeter on connecting tube and valve, the blast main be connected with tubular membrane (2) and gas-holder (4), electrical control cubicles (3) and time controling and Liquid level technique.
Described pulsed tubular membrane, is characterized in that by time controller, makes feed liquor and air inlet be that interval is carried out, the pollutent of timely cleaning filter membranes surface and fenestra.
Described pulsed tubular membrane top hole pressure pressure-controlling is at 0.1-0.4MPa.
The compressed air pressure that described pulsed tubular membrane passes into is greater than fresh feed pump more than top hole pressure 0.01MPa.
Described fresh feed pump adopts time controling, often runs several minutes to dozens of minutes and just shuts down several seconds to a few minutes
Clock; The keying of the time controller of fresh feed pump is controlled by the liquid level in former pond.
Described reservoir outlet is equipped with electrically operated valve, is controlled by time controller, and per minute is supplied gas for several times, and the time of at every turn supplying gas, compressed-air actuated pressure should be greater than pump outlet more than pressure 0.01MPa at 0.2 second to several seconds.
Above-mentioned pulsed tubular membrane, film surface and fenestra have self-cleaning function, and Automated condtrol, and the system that can ensure is run steadily in the long term and without the need to cleaning, simplifies daily cleaning, maintenance and management, reduce running cost and handling cost.The industries such as chemical industry, metallurgy, food, medicine, papermaking, printing and dyeing and sewage disposal can be widely used in.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present invention:
In figure: 1---fresh feed pump, 2---tubular membrane (2-1: inlet mouth, 2-2: opening for feed,
2-3: water outlet, 2-4: dope mouth), 3---electrical control cubicles, 4---gas-holder.
Embodiment
Below in conjunction with Figure of description, the invention will be further described.
As shown in the figure, pulsed tubular membrane, comprises fresh feed pump (1), tubular membrane (2), electrical control cubicles (3), gas-holder (4) and connecting tube.The import of fresh feed pump (1) is connected with former pond, outlet is connected with (2-2) interface of tubular membrane (2), (2-1) interface of tubular membrane (2) lower end is connected with gas-holder (4), (2-3) interface of tubular membrane (2) side is water outlet, and (2-4) interface on tubular membrane (2) top is connected with former pond.
Whole system has time controling and Liquid level function, controls fresh feed pump and pressure lock, guarantees that the operation of fresh feed pump meets processing requirement.
Pulsed tubular membrane adopts cross flow filter form, is characterized in that tubular membrane is by self-cleaning function, and tubular membrane is erect and installed, and N props up parallel connection.Water and pressurized air enter from the bottom of tubular membrane, the former water that need be filtered by fresh feed pump or biological reaction tank water are squeezed in tubular membrane, tubular membrane is utilized to carry out separating clarifying to former water or biological reaction tank water, the pressurized air of pulsed conveying simultaneously, makes particulate pollutant float in water with pressurized air and is back to former pond or biological reaction tank.
In separating clarifying process, fresh feed pump is controlled by time controller, often runs several minutes to dozens of minutes and just shuts down several seconds to several minutes, and then often runs several minutes to dozens of minutes, hockets continuously.Shutting down several seconds objects to several minutes is the pressure bounce-back filter membrane allowing the liquid of the cleaner liquid side of tubular membrane conduct oneself with dignity by liquid, reaches clean filter membrane surface and fenestra pollutent.Compressed-air actuated conveying adopts time controller to control, and per minute is supplied gas for several times, and the time of at every turn supplying gas, object allows suspended particulate be suspended in water with pressurized air be back to former pond or biological reaction tank at 0.2 second to several seconds.
The feature of pulsed tubular membrane application art of the present invention is:
1. tubular membrane is erect and is installed, and according to the size of the water yield, can prop up parallel connection by N.
2. cross flow filter form, water and pressurized air enter bottom tubular membrane.
3. water pump is controlled by time controller, intermittent operation, clean filter membrane.
4. carry pressurized air to adopt time controller to control, discharge suspended particulate.
