Description

Swirler and swirl system

Technical Field

The disclosure relates to the technical field of water treatment, in particular to a swirler and a swirling flow system.

Background

Hydrocyclones are devices that use a rotating flow for classification, and are also used for concentration and dewatering. The liquid is fed under pressure into the cyclone along the feed pipe and then undergoes a rotary motion under the restriction of the wall. The coarse particles are thrown to the wall of the vessel due to the large inertial centrifugal force and gradually flow downwards to be discharged from the bottom to be settled. The fine particles move to the wall of the device at a lower speed, and are driven by the liquid flowing towards the center to flow out of the overflow pipe to form overflow. Because the hydrocyclone separation precision is limited, micron-sized impurities (bacteria and the like) exist in overflow liquid, only pretreatment can be carried out, and items such as direct drinking water and the like which have requirements on water quality cannot be directly realized, so that the application is limited.

In one embodiment, the radial cross-section of the swirl portion 101 is circular; the radial section of the sand accumulation part 102 is circular, the diameter of the radial section of the sand accumulation part 102 refers to the inner diameter of the radial section of the sand accumulation part 102, and the wall thickness of the sand accumulation part 102 is not counted; the inlet of the overflow part is communicated with the main body part, the outlet of the overflow part extends out of the water producing part 103, and the outlet of the overflow part is not communicated with the water producing part 103. The swirling portion 101, the water generating portion 103, and the overflow portion are coaxially provided.

In some other embodiments, the outflow end of the sand trap 102 is connected to a sand drain 108.

In the cyclone 100 provided in at least one embodiment, the cyclone part and the ultrafiltration part are combined, the quality of water produced by the cyclone is guaranteed through physical entrapment, the floor area is saved to a certain extent, fluid is enabled to make spiral motion along the inner wall of the cyclone part 101 through the cyclone part 101, and separated gravel is collected through the sand accumulation part 102; the fluid which turns upwards flows into the overflow part again, part of the fluid passes through the ultrafiltration part 104, flows into the water generating part 103 in a cross flow filtration mode and flows from the water generating part 103; because of cross-flow filtration, most of the fluid flows out through the overflow part; because the overflow part is provided with the ultrafiltration part 104, the separation precision can be improved to a certain degree, and because the overflow part is inserted into the water production part 103, the damage of the ultrafiltration part 104 caused by high-speed water flow can be delayed to a certain degree.

In some embodiments, water production section 103 is configured to collect water filtered by ultrafiltration section 104 and flow out of an outlet of water production section 103. The lower end of the water producing section 103 is flush with the upper end of the sand accumulating section 102, which facilitates the spatial positioning of the lower end of the ultrafiltration section 104. At least part of the upper structure of the water-producing portion 103 protrudes from the swirling portion 101.

In some embodiments, the overflow section further comprises an upper tube 105, wherein the upper end of the upper tube 105 extends out of the water-producing section 103, and the lower end of the upper tube 105 is communicated with the upper end of the ultrafiltration section 104.

In some embodiments, cyclone 100 further comprises an inlet tube 109, inlet tube 109 being in communication with cyclone section 101, inlet tube 109 being adapted to facilitate providing an initial velocity to fluid entering cyclone section 101. In one embodiment, the inlet pipe 109 is provided at an upper end of the cyclone part 101.

In some embodiments, the outlet of the inlet pipe 109 is arranged tangentially to the outer circumference of the swirling part 101, and when a certain pressure is applied to the fluid in the inlet pipe 109, the fluid enters the swirling part 101 tangentially, and then spirally moves along the inner wall of the swirling part 101 and flows downwards.

In some embodiments, the lower end face of the overflow is flush with the upper end face of the sand trap 102; this is favorable to reducing the turbid liquid that contains more sand and gets into overflow portion.

In some other embodiments, the lower end surface of the overflow portion is higher than the upper end surface of the sand-accumulating portion 102, so that the turbid liquid containing more sand can be further reduced from entering the overflow portion.

In some embodiments, a closure cap 110 is attached between the edge of the lower end of the overflow section and the edge of the lower end of the water-producing section, which prevents the upturned fluid in the main body section from directly entering the water-producing section, i.e., ensures that the upturned fluid does not enter the water-producing section after passing through the ultrafiltration section 104.

In some embodiments, the ultrafiltration section 104 is a tubular ceramic membrane. In one embodiment, the cyclone 100 has a diameter of 50mm to 150mm, and both ends of the ultrafiltration section 104 are not sealed; the filtration pore size of the tubular ceramic membrane is 50nm to 200nm, for example: the filtering aperture of the tubular ceramic membrane is 100nm or 150 nm; it should be noted that the specific filter pore size can be selected according to actual needs.

Referring to FIG. 2, in some embodiments, the diameter of the radial cross-section of inlet tube 109 decreases from the inlet of inlet tube 109 toward the outlet of inlet tube 109, which may increase the initial velocity of the fluid entering swirl portion 101.

In one or more embodiments of the present disclosure, there is also provided a swirling system, including: at least one cyclone 100, which is a high precision, short flow cyclone system in series with hydrocyclones 100.

step S2, making the fluid after swirling flow out along an overflow path;

and step S3, performing cross-flow filtration on at least part of the fluid flowing along the overflow path, and collecting the fluid after the cross-flow filtration.

The water purification method also comprises the steps that the fluid flowing out along the overflow path flows downwards in a spiral flow mode, and the fluid after the rotational flow flows out along the overflow path; the water purification method repeats steps S1 and S2 at least once for the fluid flowing along the overflow path.

step S1, the fluid is made to enter from the inlet pipe 109 of the cyclone 100 and flow downward in a spiral flow manner by the cyclone 101;

step S3, performing cross-flow filtration on at least a part of the fluid flowing along the overflow path through the ultrafiltration part 104 of the overflow part, and collecting the fluid subjected to cross-flow filtration by the water generation part 103.

In this water purification method, since the plurality of cyclones 100 are connected in series, the fluid flowing out of the outlet of the overflow portion of the cyclone 100 located at the first position enters the water inlet pipe of the cyclone 100 located at the second position, and the fluid flowing out of the outlet of the overflow portion of the cyclone 100 located at the second position enters the cyclone 100 located at the third position, and the flow sequentially progresses, and the fluid flows out of the outlet of the overflow portion of the cyclone 100 located at the end position and then enters the next water treatment process. The water from each water-producing portion 103 of the plurality of cyclones 100 connected in series is collected for later use.

It should be noted that the number of the cyclones 100 used in the water purification method is one or more, and when two or more cyclones 100 are used, the number of the cyclones 100 may be 2 to 20, and the like.
