The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in FIGS. 1, 2 and 3, an embodiment relates to a turbulator, which comprises a turbulator pipe 100, wherein the turbulator pipe 100 comprises a first pipe segment 110 and a second pipe segment 120 connected with the first pipe segment 110 in a bending manner, the first pipe segment 110 is provided with a first turbulating channel 111, the second pipe segment 120 is provided with a second turbulating channel 121 communicated with the first turbulating channel 111, and one end of the first turbulating channel 111, which is far away from the second turbulating channel 121, is provided with an outlet 1111 for communicating with a feed port 211 of a swirler 200; the cross-sectional shapes of the first turbulence removing channel 111 and the outlet 1111 are the same as the cross-sectional shape of the feed inlet 211, and an arc-shaped transition channel 130 is arranged between the first turbulence removing channel 111 and the second turbulence removing channel 121.

When the dirty liquid enters the cyclone 200 through the turbulator, the dirty liquid firstly flows into the arc-shaped transition passage 130 through the second turbulator passage 121, then the dirty liquid is partially gathered near the arc surface of the arc-shaped transition passage 130 under the action of the arc-shaped transition passage 130 by centrifugal force, so that the dirty liquid is primarily layered into a concentrated liquid layer and a clear liquid layer, further the dirty liquid entering the first turbulator passage 111 is more gradual, then the layered dirty liquid is modified into a fluid shape identical to the cross-sectional shape of the feed port 211 under the action of the first turbulator passage 111, and finally the fluid flows into the feed port 211 from the outlet 1111. Thus, the shape of the dirty liquid entering the feed inlet 211 is the same as the cross-sectional shape of the feed inlet 211, so that the turbulent flow of the dirty liquid at the feed inlet 211 is eliminated, and the separation effect of the cyclone on the composite powder carrier is improved.

The contaminated liquid is excess sludge in the HPB process, which contains composite powder carriers to which microorganisms are attached and fine-particle impurities, and has a fluid property because the water content of the excess sludge is 97%. Meanwhile, when the dirty liquid flows through the arc-shaped transition channel 130, because the adhesion force to the composite powder carrier will be reduced after the microorganism is aged, the aged microorganism attached to the surface of the composite powder carrier can be stripped by the centrifugal shearing force generated by the dirty liquid in the arc-shaped transition channel 130 in an effective gradient manner, so that the cyclone 200 can screen out the stripped aged microorganism, and the recovery quality of the composite powder carrier is improved.

The bent connection means that the axis of the first pipe segment 110 and the axis of the second pipe segment 120 form an included angle. With particular reference to fig. 2, the axis of the first tube segment 110 is at an angle greater than 90 ° to the axis of the second tube segment 120.

Specifically, in the present embodiment, the feeding hole 211 of the cyclone 200 is a rectangular feeding hole 211 with one side tangential to the wall of the cyclone chamber 210. Correspondingly, the cross-sectional shapes of the first turbulence removing channel 111, the second turbulence removing channel 121 and the outlet 1111 are all rectangles with the same cross-sectional shape as the feed inlet 211. In this way, the dirty liquid flowing into the vortex chamber 210 from the feed inlet 211 contacts the chamber wall of the vortex chamber 210 in a surface contact manner, so that the separation of the composite powder carrier in the dirty liquid can be improved.

In some embodiments, the length of the first turbulence removal channel 111 is greater than 80 cm. Thus, it is ensured that the contaminated liquid can have enough time to be corrected by the first turbulence removing passage 111 when passing through the first turbulence removing passage 111, thereby flowing into the feed port 211 more stably.

As shown in FIG. 3, in some embodiments, the intersections between adjacent sidewalls of the first turbulation channel 111 have a first arcuate transition 1112, and the intersections between adjacent sidewalls of the second turbulation channel 121 have a second arcuate transition 1212. Thus, when the contaminated liquid passes through the first turbulence removing channel 111 and the second turbulence removing channel 121, the composite powder carriers in the contaminated liquid will not be deposited in the first turbulence removing channel 111 and the second turbulence removing channel 121.

In some embodiments, the second turbulence removing channel 121 includes a reducing channel (not shown), and a connecting channel (not shown) connecting the arc transition channel 130 and the reducing channel, the end of the reducing channel away from the connecting channel has an inlet 1211, the cross-sectional shape of the connecting channel is the same as the cross-sectional shape of the first turbulence removing channel 111, and the cross-sectional shape of the reducing channel gradually changes from the inlet 1211 to the connecting channel. Specifically, the cross-sectional shape of the inlet 1211 is circular, which is the same as the cross-sectional shape of the circular feed tube. When the inlet 1211 is communicated with the circular supply pipe, the polluted liquid can flow into the reducing channel from the circular supply pipe through the inlet 1211, and the fluid shape of the polluted liquid is gradually changed from a circular cross section to a rectangular shape which is the same as the cross section of the first turbulence removing channel 111 under the action of the reducing channel. Therefore, the dirty liquid can avoid turbulence generated by the sudden change of the cross section shape of the fluid under the action of the reducing channel, thereby influencing the separation effect of the arc-shaped transition channel 130 on the dirty liquid.

In some embodiments, the turbulence removal pipe 100 is provided with a first connection flange 140 and a second connection flange 150 at both ends, respectively. In this way, the connection or disconnection of the turbulence removal pipe 100 to the cyclone 200 can be facilitated by the provision of the first connection flange 140, and the connection or disconnection of the turbulence removal pipe 100 to the feed line can be facilitated by the provision of the second connection flange 150.

Further, a sealing member (not shown) is disposed on each of the first connecting flange 140 and the second connecting flange 150. In this way, the tightness of the filtering line is ensured when the turbulence removing pipe 100 is interposed between the feed line and the cyclone 200.

Wherein, the sealing element can be selected from but not limited to a rubber sealing ring.

In some embodiments, the first tube segment 110 and the second tube segment 120 are both comprised of a stainless steel material. In this way, the corrosion resistance of the turbulator is enhanced.

An embodiment relates to a fine particle fluid separation device, which comprises the turbulence eliminator and a cyclone 200 connected with the turbulence eliminator, wherein the cyclone 200 is provided with a cyclone cavity 210 with a feed inlet 211, a sinking port 212 and a spillway overflow port 213, and the feed inlet 211 is communicated with an outlet 1111; the cross-sectional shapes of the first turbulence removing channel 111 and the outlet 1111 are the same as the cross-sectional shape of the feed inlet 211, and an arc-shaped transition channel 130 is arranged between the first turbulence removing channel 111 and the second turbulence removing channel 121.

In the fine particle fluid separation device, the turbulence eliminator is arranged between the feeding pipeline and the feeding hole 211 of the cyclone 200, so that the condition that dirty liquid is easy to generate turbulence at the feeding hole 211 of the cyclone 200 can be avoided, the dirty liquid can smoothly enter the cyclone chamber 210, and further the composite powder carrier can be discharged from the sinking port 212 more.

In some embodiments, the axis of the arc transition passage 130 is disposed parallel to the swirl axis 300 of the swirler 200. When dirty liquid flows into the variable diameter channel from the feeding pipeline through the inlet 1211, the fluid cross-sectional shape of the dirty liquid is gradually changed into the same cross-sectional shape as that of the second turbulence removal channel 121 under the action of the variable diameter channel, and then the composite powder carriers in the dirty liquid are partially gathered to the area close to the centrifugal arc surface under the action of the arc transition channel 130, so that a concentrated liquid layer with high concentration is formed, and a clear liquid layer with low concentration is formed in the area far away from the centrifugal arc surface; then, the layered dirty liquid corrects the fluid shape of the dirty liquid under the action of the first turbulence removal channel 111; finally, the polluted liquid enters the vortex chamber 210 from the rectangular feed inlet 211. Because the axis of the arc surface of the arc transition passage 130 is parallel to the rotational flow axis 300 of the cyclone 200, the thick liquid layer which just enters the rotational flow chamber 210 directly rotates along the chamber wall of the rotational flow chamber 210, thereby improving the effect of the cyclone 200 on the rotational flow separation of the dirty liquid.

The swirling axis 300 is a rotational axis of the dirty liquid that centrifugally rotates in the swirling chamber 210. The centrifugal arc is an arc tangent to the wall of the swirling chamber 210 by one side of the first pipe segment 110.
