Description

Technical Field

[0001] This invention relates to the field of wastewater filtration, and more specifically, to a novel high-efficiency filtration technology. Background Technology

[0002] Filtration is the process of purifying fluids using specialized devices. There are many types of filtration, and a wide range of systems are used, including solid-liquid, solid-gas, large particles, and small particles. Filtration involves the process of separating the liquid (or gas) from the liquid (or gas) in a suspension (or a gas containing solid particles and generating heat) under the action of a driving force or other external force. Solid particles and other substances are trapped by the filter medium, thereby separating the solids and other substances from the liquid (or gas).

[0003] Wastewater filtration refers to the separation of suspended solid particles from liquids, especially toxic media. Wastewater treatment filtration primarily treats wastewater, enabling its recycling. Applications of wastewater filtration include water supply and drainage systems, continuous casting and rolling mill water systems, blast furnace water systems, turbid / clean circulating water systems, and makeup water systems in the metallurgical industry; turbine cooling water systems in power plants; wet boiler cooling water systems; cooling water systems for large air compressors, large oxygen generators, and large air conditioners; direct-flow cooling filtration systems for steam turbines using seawater, lake water, and river water; and even widespread use in agricultural drip irrigation systems.

[0004] Common wastewater filtration methods include sedimentation and permeation. Sedimentation filtration is time-consuming and inefficient, while permeation filtration requires more screens / layers for higher filtration requirements, resulting in a larger space requirement. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the technical problem to be solved by this invention is to propose a novel high-efficiency filtration technology that is small in size and fast in filtration.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This invention provides a novel high-efficiency filtration technology, comprising: a clear liquid chamber, wherein an upper diversion cavity is provided at the top of the clear liquid chamber and a lower diversion cavity is provided at the bottom of the clear liquid chamber; the clear liquid chamber is also provided with an inlet and an outlet, the inlet communicating with the lower diversion cavity and the outlet communicating with the interior of the clear liquid chamber; and filter tubes, wherein a plurality of filter tubes are disposed in the clear liquid chamber, and chucks are provided at both ends of the filter tubes corresponding to the upper and lower diversion cavities; the upper and lower diversion cavities cooperate to control the inlet and outlet directions of the filter tubes, and the filter tubes are divided into an upstream pipe and a downstream pipe according to the water flow direction; a first diversion isolation plate is provided in the upper diversion cavity of the lower diversion cavity to divide the filter tubes into two parts, one of which is the upstream pipe; a second diversion isolation plate in an L-shape is provided in the upper diversion cavity, the second diversion isolation plate dividing the other part of the filter tubes separated by the first diversion isolation plate into equal parts, one of which is the downstream pipe.

[0008] Furthermore, a third diversion isolation plate is provided in the lower diversion cavity, which divides the other filter tube separated by the second diversion isolation plate into two parts, one of which is the upper flow tube. A fourth diversion isolation plate is provided in the upper diversion cavity.

[0009] Furthermore, the fourth diversion isolation plate divides the other filter tube separated by the third diversion isolation plate into two parts, one of which is a downstream pipe and the other is an upstream pipe. The upstream diversion cavity is provided with a drain outlet for sewage discharge, which is located on the side of the fourth diversion isolation plate away from the third diversion isolation plate.

[0010] In a preferred embodiment of the present invention, the bottom of the clear liquid chamber is further provided with a support frame that provides support.

[0011] In a preferred embodiment of the present invention, the sidewall of the chuck is in close contact with the inner wall of the clear liquid chamber.

[0012] In a preferred embodiment of the present invention, a gap is left between the outer walls of the filter tubes.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] (1) In this invention, the filter tubes inside the filter device are connected in parallel and then in series by a specially designed diversion isolation plate. The raw water flows inside all the filter tubes. At the same time, under the action of pressure, the suspended solids are intercepted through the micropores of the filter tubes. The clean water is collected in the clear liquid chamber of the filter device. The intercepted suspended solids are carried by the water flow to the next stage filter tube. The flow rate of the raw water is reduced, and the number of filter tubes is also reduced accordingly. Thus, by connecting in parallel and then in series, cross-flow filtration can be achieved without a cross-flow pump, so as to achieve the purpose of concentrating suspended solids.

[0015] (2) In this invention, the sewage is repeatedly filtered in the clear liquid chamber, and the filtration efficiency will not be weakened. At the same time, the internal space of the equipment is reasonably utilized, reducing the size of the sewage discharge equipment. This invention also has the advantages of being easy to operate and implement. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1:

[0029] like Figures 1 to 9As shown, this embodiment discloses a novel high-efficiency filtration technology, including: a clear liquid chamber 1, with an upper diversion cavity 10 at the top and a lower diversion cavity 11 at the bottom; an inlet 12 and an outlet 13 on the clear liquid chamber 1, the inlet 12 communicating with the lower diversion cavity 11 and the outlet 13 communicating with the interior of the clear liquid chamber 1; and filter tubes 2, with several filter tubes 2 disposed within the clear liquid chamber 1, and chucks 3 at both ends of the filter tubes 2 corresponding to the upper diversion cavity 10 and the lower diversion cavity 11. The upper diversion chamber 10 and the lower diversion chamber 11 work together to control the inlet and outlet directions of the filter pipe 2. The filter pipe 2 is divided into an upper pipe 20 and a lower pipe 21 according to the water flow direction. The inlet 12 discharges sewage into the lower diversion chamber 11. After the sewage enters the clear liquid chamber 1 through the upper pipe 20, it flows into the upper diversion chamber 10. Since the upper diversion chamber 10 is separated by the second diversion isolation plate 15, the sewage can only enter the separated part and does not pass through the lower pipe 21, thus allowing the sewage to complete two round trip filtrations.

[0030] Furthermore, the lower diversion chamber 11 and the upper diversion chamber 10 are provided with a first diversion isolation plate 14 that divides the filter tube 2 into two parts, one of which is the upper flow tube 20; the upper diversion chamber 10 is provided with an L-shaped second diversion isolation plate 15, which divides the other part of the filter tube 2 separated by the first diversion isolation plate 14 into equal parts, one of which is the lower flow tube 21; the sewage re-enters the lower diversion chamber 11 through the lower flow tube 21 separated by the second diversion isolation plate 15. Since the lower diversion chamber 11 is simultaneously blocked by the first diversion isolation plate 14 and the third diversion isolation plate 16, the sewage can only enter the separated and unfiltered upper flow tube 20. The sewage re-enters the upper diversion chamber 10 through the upper flow tube 20. Since the upper diversion chamber 10 is simultaneously blocked by the second diversion isolation plate 15 and the fourth diversion isolation plate 17, the sewage can only enter the separated and unfiltered lower flow tube 21, thus allowing the sewage to complete the second round of filtration.

[0031] Furthermore, a third diversion isolation plate 16 is provided in the lower diversion chamber 11. The third diversion isolation plate 16 divides the other part of the filter tube 2 separated by the second diversion isolation plate 15 into two parts, one of which is the upper flow pipe 20. A fourth diversion isolation plate 17 is provided in the upper diversion chamber 10. The fourth diversion isolation plate 17 divides the other part of the filter tube 2 separated by the third diversion isolation plate 16 into two parts, one of which is the lower flow pipe 21 and the other is the upper flow pipe 20. A sewage outlet 18 for sewage discharge is provided in the upper diversion chamber 10. The sewage outlet 18 is located on the side of the fourth diversion isolation plate 17 away from the third diversion isolation plate 16. When the sewage returns to the lower diversion chamber 11, since the lower diversion chamber 11 is blocked by the first diversion isolation plate 14 and the third diversion isolation plate 16 at this time, the sewage can only enter the separated and unused upper flow pipe 20. The sewage re-enters the upper diversion chamber 10 through the upper flow pipe 20 and is discharged out of the clear liquid chamber 1 through the sewage outlet 18.

[0032] In order to enable the clear liquid chamber 1 to be placed vertically on the ground, a support frame 4 is also provided at the bottom of the clear liquid chamber 1 to provide support.

[0033] To prevent sewage from seeping into the clear liquid chamber 1 from the chuck 3, the side wall of the chuck 3 is tightly fitted with the inner wall of the clear liquid chamber 1.

[0034] In order to enable the filter tube 2 to filter sewage better, gaps are left between the outer walls of the filter tube 2.

[0035] The working process and principle of the present invention are as follows: First, the inlet 12 discharges the sewage into the lower diversion chamber 11. After the sewage enters the clear liquid chamber 1 through the upper flow pipe 20, it flows into the upper diversion chamber 10. Since the upper diversion chamber 10 is separated by the second diversion isolation plate 15, the sewage can only enter the separated section and does not pass through the lower flow pipe 21, thereby allowing the sewage to complete two round trip filtrations.

[0036] Subsequently, the sewage re-enters the lower diversion chamber 11 through the lower diversion pipe 21 separated by the second diversion isolation plate 15. Since the lower diversion chamber 11 is simultaneously blocked by the first diversion isolation plate 14 and the third diversion isolation plate 16, the sewage can only enter the separated and unfiltered upper diversion pipe 20. The sewage then re-enters the upper diversion chamber 10 through the upper diversion pipe 20. Since the upper diversion chamber 10 is simultaneously blocked by the second diversion isolation plate 15 and the fourth diversion isolation plate 17, the sewage can only enter the separated and unfiltered lower diversion pipe 21, thus allowing the sewage to complete the second round-trip filtration.

[0037] Then the sewage returns to the lower diversion chamber 11. Since the lower diversion chamber 11 is blocked by the first diversion isolation plate 14 and the third diversion isolation plate 16 at the same time, the sewage can only enter the separated and unpassed upper pipe 20. The sewage enters the upper diversion chamber 10 again through the upper pipe 20 and is discharged out of the clear liquid chamber 1 through the sewage outlet 18.

[0038] Finally, the filtered water can be discharged from the clear liquid chamber 1 through the drain outlet 13. As the wastewater flows within the filter pipe 2, the liquid continuously seeps out, thus achieving filtration efficiency. Because the water flow rate in the wastewater decreases, the flow velocity also decreases. By using equally spaced filter pipes 2, the inflow rate of filter pipes 2 increases, offsetting the decrease in flow velocity caused by the reduced water flow, allowing the wastewater to maintain a high flow velocity, thereby achieving the goal of high-efficiency filtration. Furthermore, the specific reduction in the number of filter pipes 2 in this scheme is calculated based on the data of the original water reduction, thus ensuring that each pipe... The water flow velocity inside the pipe is sufficient to carry away most of the intercepted suspended solids. As the amount of raw liquid decreases, more and more suspended solids are intercepted, and the concentration of suspended solids in the water continues to rise until it is discharged from the last stage filter pipe 2, where the concentration reaches its maximum. The concentration ratio can exceed 100 times that of the raw water. The number of stages can be designed according to specific requirements; the more stages, the greater the concentration ratio. At the same time, the internal space of the equipment is used in a reasonable way to reduce the size of the sewage discharge equipment, so that the equipment has the advantages of small size and fast filtration without affecting the sewage discharge effect.

[0039] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
