Background
Along with the continuous acceleration of the industrialized process and the urbanization process in China, more and more waste water is generated in the industrial, commercial and civil fields, the waste water is required to be filtered during treatment to reduce the content and turbidity of suspended matters, meanwhile, because of the serious shortage of water resources in China and the increase of the environmental protection supervision, the yield of seawater desalination and the yield of water treatment in enterprises are continuously increased, a seawater desalination device and most of reclaimed water treatment devices are required to use a water filter, the conventional water filter generally takes quartz sand, a metal filter core or a non-metal high polymer material as a filter core material, the non-soluble suspended matters are blocked by the gaps of the filter core material after water enters the filter, the purposes of isolating and removing the suspended matters are achieved, but the suspended matters are gathered on the surface of the water inlet side of the filter core material in the filtering process, and the pressure difference between the two sides of the filter core is, the resistance is increased during water filtration, and the efficiency and the effect of water filtration are reduced.
At present, water treatment devices in China are all based on the pressure difference and backwashing principle, suspended matters are gathered on the water inlet side of a filter element material in the filtering process, the pressure on the water inlet side of the filter element material is continuously increased, the backwashing work opposite to the filtering process needs to be executed when the filtering resistance is increased to a certain value, the suspended matters gathered on the water inlet side of the filter element are reversely washed by using clean water, the performance of the filter element is recovered by the reverse washing, the filter is enabled to reach the design performance again, and the following defects and shortcomings exist in the working principle:
1. In the back washing process, an additional differential pressure monitoring device, a back washing water tank, a back washing pump and a valve for switching the water flow direction are required to be arranged, so that the equipment investment is increased undoubtedly;
2. The back washing process also needs to occupy the normal working time of the filter, and according to different application fields and water quality, the back filtering process usually needs to occupy 5% -10% of the working time of the filter, so that the effective working time of the equipment is greatly reduced, and the benefit of the equipment is reduced;
3. Although the pressure difference of part of filtering equipment after back washing meets the requirement, the filtering effect is obviously reduced, and the water quality after filtering is often reduced, so that the water quality is reduced;
4. The conventional backwashing device cannot solve the problem that the filter element is blocked due to the growth of microorganisms in the filter.
The high-efficiency water filter disclosed by the invention can solve the problems, avoid backwashing time, reduce backwashing equipment, increase equipment benefit, generate continuous and stable filtering effect in the filtering process, and also can be optionally matched with functions of sterilizing and killing microorganisms.

The data in table 2 obtain figure 4 (curve of G along with time change), and it can be seen in figure 4 that the purified water flow G of the water outlet pipe of the high-efficiency water filter is kept in a stable numerical range within 33.5h, the purified water flow G of the water pipe is repeatedly reduced in 33.5h of the traditional backwashing filter, and the purified water is only intermittently produced during backwashing, so that the water purification efficiency is greatly reduced.
by integrating the embodiments 2 to 12, it can be seen from table 1 that the pressure difference value Δ F of the inlet and outlet of the filter barrel (1) decreases with the increase of the diameter a of the air bubble, the taper b of the filter element, and the flow rate c of the air bubble, when the diameter a of the air bubble is greater than 5mm, the pressure difference value Δ F of the inlet and outlet of the filter barrel (1) and the change of the purified water flow rate G at the water pipe are no longer obvious, and the high efficiency water filter is determined by considering the factors of the equipment manufacturing cost, the operating cost, the filtering flow rate, and the like, the size of the air bubble 9 generated by the aeration pipe 3 is 5mm, namely, the value of a is 5mm, the taper of the filter element 2 is 15 °, the value of b is 15 °, the flow rate of the air bubble 9 is 600 to 800L/h, namely, the value of c is.
The working principle of the invention is as follows: a high-efficiency water filter adopts the aeration principle in the sewage treatment process to continuously clean the water inlet side surface of a filter element 2 in a filter barrel 1, and always keeps the suspended matters on the water inlet side of the filter element 2 incapable of gathering, thereby achieving the purpose that the high-efficiency water filter can continuously work and avoiding time waste in the back washing process, sewage enters the filter barrel 1 from a water inlet pipe 4, water is driven to flow into the filter element 2 from the outer surface of the filter element 2 under the action of pressure difference, the filtered water is converged in the filter element 2 and then flows out through a water outlet pipe 5 to complete the filtering process, in the filtering process, bubbles 9 generated by an aeration circulating pump 7 are introduced into an aeration pipe 3, the aeration pipe 3 at the lower part of the filter element 2 continuously emits bubbles 9 with a specific flow and size, the bubbles 9 form disturbance with the outer surface of a conical filter element 2 in the rising process, and continuously generate shearing force for clearing the suspended matters, therefore, suspended matters can not be gathered on the outer surface of the filter element 2, the pressure difference between the inside and the outside of the filter element 2 is stabilized in a specific range, and the continuity and the stability of the water purification work are kept.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
