Abstract
The present invention discloses an aeration device applied to membrane components and aims at providing an aeration device which is applied to membrane components so as to lead gas to form stable airflow in the inside of the components with a good membrane cleaning effect and can prolong the service life of membrane yarn and be able to carry through to produce water at two ends. The device includes an aeration body and an air collection chamber is arranged in the aeration body. The outside of the aeration body is connected with multiple closed air chambers communicated with the air collection chamber. Each air chamber is provided with multiple aeration holes. The upper part of the aeration body is provided with a water collection chamber and multiple outlet openings are arranged in the water collection chamber. The lower end of the aeration body is provided with multiple inlet openings. The aeration body is provided with a channel to communicate the inlet openings and outlet openings. The aeration device of the present invention leads gas to form continuous and stable airflow after entering the inside of the components so as to lead the up and down aeration of the membrane yarn to be uniform. The present invention has a good pollution removing and guarantees continuous and stable application of the components. And up and down arrangement of gas is uniform and the up and down force of the membrane yarn is consistent. The present invention has prolonged the service life of the membrane yarn.
Description
Technical field
The present invention relates to water treatment field, in particular, relate to a kind of aerating apparatus that is used for hollow fiber film assembly.
Background technology
Hollow fiber film assembly has been widely used in the membrane filtration processing of various Industrial processes now, ultrapure water as washing semi-conductor, the processing of petrochemical wastewater and sea water desaltination etc., in above these fields, pillar or curtain formula external pressure hollow fiber film assembly have been adopted mostly, in above-mentioned external-pressing film assembly, generally adopted gas scouring method to remove film and polluted at present, different manufacturers has used different aeration modes.In above-mentioned membrane module, mostly in the assembly bottom opening, gas enters component internal by the pore that is distributed in the assembly end face and forms aeration.Its shortcoming is:
1. gas directly enters component internal from end face, and the aeration degree of uniformity is poor, and the aeration effect is bad, influences the cleaning performance of film.
2. owing to the restriction of manufacturing process, the end face pore is bigger, and gas consumption is big during aeration, the energy consumption height.
3. a large amount of gases enter from the bottom, film silk root are impacted bigger, easily cause fracture of film silk and fatigue damage, reduce assembly work-ing life.
4. can't carry out both-end and produce water, film silk utilization ratio reduces.
5. the manufacturing process complexity easily forms product defects.
Summary of the invention
The present invention is in order to overcome weak point of the prior art, to provide a kind of membrane module that is used for to make gas form stable air-flow in component internal, and it is effective that film cleans, and can prolong film silk work-ing life and can carry out the aerating apparatus that both-end produces water.
The present invention is achieved through the following technical solutions:
A kind of aerating apparatus that is used for membrane module is characterized in that, comprises the aeration body, is provided with collection chamber in the described aeration body, and the described aeration body outside is connected with a plurality of closed air chambers that are communicated with collection chamber, and each air chamber is provided with a plurality of solarization air caps.
Described aeration body top is provided with collecting chamber, is provided with a plurality of posticums in collecting chamber, is provided with a plurality of prosopyles in aeration body lower end, and described aeration body is provided with the water channel that is communicated with prosopyle and posticum.
The bottom of described collection chamber is connected with the aeration column sealing that has gas passage.
Described aeration body is an open column shape body.
The present invention has following technique effect:
1. gas enters component internal by aerating apparatus, forms the air-flow of continous-stable, and aeration is even up and down to make the film silk, and it is good to remove pollution effects.Guarantee that the assembly continous-stable uses.
2. gas is evenly distributed up and down, and lower stress unanimity on the film silk has prolonged film silk work-ing life.
3. because the aeration effect is better, therefore can reduce gas consumption, energy consumption reduces.
4. establish the product aquaporin in the aerating apparatus, can realize that the membrane module both-end produces water, has improved film silk utilization ratio.
5. can adopt mold injection molding, simplify production technique, the product defects of having avoided complex process to bring.

Embodiment
Below in conjunction with the drawings and specific embodiments to the detailed description of the invention.
The synoptic diagram of aerating apparatus of the present invention such as Fig. 1-shown in Figure 5, comprise aeration body 2, be provided with collection chamber 4 in the described aeration body 2, aeration body 2 outsides are connected with a plurality of closed air chambers 1 that are communicated with collection chamber by the pore 8 on the aeration body, and each air chamber is provided with a plurality of solarization air caps 3.Air chamber quantity is generally the 2-20 sheet, and the quantity of solarization air cap can be selected between 1-1000.For simplified manufacturing technique, the aeration body can be an open column shape body, and the hollow parts upper end closed is as collection chamber.The bottom of collection chamber is tightly connected by sealing-ring 9 with the aeration post 11 that has gas passage 13.
In order to satisfy the needs that both-end produces water, the also double passage that produces water of doing of aeration body.In order to make aeration and to produce water and do not disturb mutually, be provided with collecting chamber 6 on aeration body 2 tops, in collecting chamber, be provided with a plurality of posticums 7, be provided with a plurality of prosopyles 5 in aeration body lower end, the aeration body is provided with the water channel 12 that is communicated with prosopyle and posticum.
This device can adopt plastics or metal to make, the preferred stainless steel of metal, and plastics can adopt materials such as ABS, UPVC, PC, PET, synthetic glass, preferred ABS or UPVC etc.
During use, the end face of the lower end of aeration body and membrane module casting resin 14 forms same plane, and air chamber is distributed between the film silk, air inlet port 16 sealings on aeration post and the end cap 15.Header 10 is communicated with collecting chamber.Gas enters collection chamber 4 by the gas passage 13 in the aeration post 11, thereby enters air chamber 1 by pore 8, enters membrane module inside by solarization air cap 3 again.Because solarization air cap quantity is many, be evenly distributed, thereby the gas that enters in the membrane module is evenly distributed up and down, form the air-flow of continous-stable, aeration is even up and down to make the film silk, and it is good to remove pollution effects, guarantees that the assembly continous-stable uses.And lower stress unanimity on the film silk has prolonged film silk work-ing life.
When the needs both-end produces water, filtered water enters between cast end face 14 and the end cap 15, enter the prosopyle 5 of aeration body bottom under pressure, enter collecting chamber by the water channel on the aeration body 12, posticum 7, flow out from the membrane module the other end by header 10 then, realize that both-end produces the single-ended water outlet of water.
Although relate to a kind of aerating apparatus that is used for membrane module and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from the spirit and scope of the present invention, all variations and modification are all within the scope of the present invention.
