[0037] In a first aspect, the present embodiment provides a clarifier, which comprises a throat 1, a first reaction chamber 5, a second reaction chamber 6 and a separation chamber 3. Figure 1 As shown, it comprises a throat 1, a first reaction chamber 5, a second reaction chamber 6 and a separation chamber 3;

[0038] The lower end of the clarifier is closed, and the bottom of the clarifier is a inverted V-shaped structure 18.

[0039] The throat pipe 1 is arranged in the center of the bottom of the clarifier; the first reaction chamber 5 is arranged in the upper part of the throat pipe 1, and the annular second reaction chamber 6 is arranged outside the first reaction chamber 5; the first reaction chamber 5 is connected to the second reaction chamber 6 from the top, and the second reaction chamber 6 is connected to the separation chamber 3 from the bottom; the bottom side of the separation chamber 3 is provided with a sludge discharge pipe 14, and the top of the separation chamber 3 is connected to the water outlet weir 7.

[0040] The throat pipe 1 is in the shape of a horn with a large upper part and a small lower part.

[0041] The annular inclined pipe 4 is arranged between the upper part of the separation chamber 3 and the second reaction chamber 6, and the water outlet of the separation chamber 3 enters the water outlet weir 7 through the annular inclined pipe 4.

[0042] In this embodiment, the sewage with the added medicament enters the first reaction chamber 5 from the throat pipe 1, and a large amount of sewage is subjected to a strong upward impact force due to the sharp reduction of the cross-sectional area of the throat pipe 1 during the upward movement. The sewage and the medicament are subjected to a preliminary flocculation reaction in the first reaction chamber 5 of the throat pipe 1. The sewage subjected to the preliminary flocculation reaction is directly impacted to the top of the second reaction chamber 6 due to the strong upward impact force, so that the water flows from the top of the second reaction chamber 6 to the second reaction chamber 6, and the sewage and the medicament are subjected to a secondary flocculation reaction. The water and impurities in the sewage are further separated, and clear water, flocculation and sludge are obtained. Due to the sudden expansion of the cross-sectional area of the second reaction chamber 6, the flow rate of the water is reduced, the clear water flowing to the separation chamber 3 rises in the separation chamber 3, the flocculation and sludge flowing to the separation chamber 3 descend in the separation chamber 3, and then descend to the bottom of the separation chamber 3, so that the flocculation and sludge are discharged from the sludge discharge pipe 14, and the clear water rises to the annular inclined pipe 4 at the upper end of the separation chamber 3. Since the passage of the annular inclined pipe 4 is in an inclined structure, the clear water with suspended solids is attached to the inner wall of the annular inclined pipe 4. The clear water flows to the water outlet weir 7 through the annular inclined pipe 4, and then is discharged from the water outlet weir 7.

[0043] In this embodiment, the cooperation of the first reaction chamber 5 and the second reaction chamber 6 enables the sewage and the medicament to be fully mixed, increases the flocculation time, improves the clarity of the clear water, and enables the flocculation and sludge to be separated from the clear water. The flocculation and sludge sink downward, and the clear water rises upward, further improving the clarity of the clear water, and the flocculation and sludge are discharged through the sludge discharge pipe 14. Specifically, the flocculation and sludge stay in the first reaction chamber 5 for 15-20s, and stay in the second reaction chamber 6 for 90s at the longest, so as to ensure that the water and sludge in the sewage are fully separated.

[0044] The water is filtered by the annular inclined pipe 4. The annular inclined pipe 4 is combined with the first reaction chamber 5, the second reaction chamber 6 and the separation chamber 3, and the clarity of the water is further improved.

[0045] The bottom of the separation chamber 3 is provided with the inverted V-shaped structure 18. The inclined surface of the inverted V-shaped structure 18 is convenient for the flocculation and sludge to be collected at the bottom of the separation chamber 3, so that the flocculation and sludge are conveniently discharged.

[0046] The throat pipe 1 is provided with the structure of large at the top and small at the bottom. The sewage has a strong impact force when flowing out of the throat pipe 1, and is impacted to the top of the second reaction chamber 6. The sewage is convenient for the flocculation reaction with the reagent in the first reaction chamber 5 with the large throat pipe 1, so as to provide a reaction space for the flocculation reaction of the sewage and the reagent, so that the water and impurities are separated, and the flocculation reaction of the sewage and the reagent is increased.

[0047] The device of the embodiment makes the sewage perform twice flocculation reaction. The size of the flocculation is increased in turn when the sewage performs the flocculation reaction each time, the flocculation effect is increased, and the clarity of the water is further improved after the filtration after the twice flocculation reaction. The twice flocculation reaction and the filtration are continuously performed, the working efficiency is improved, the production cost is reduced, the structures of the clarifier are integrated, the occupied space is reduced, and the device is suitable for popularization and application.

[0048] In some embodiments, the separation chamber 3 is provided with the emptying pipe 8. The emptying pipe 8 is located above the sludge discharge pipe 14. The emptying pipe 8 can be used to discharge any one of the clear water, the sewage, the flocculation or the sludge.

[0049] In some embodiments, the sludge discharge pipe 14 is provided with six sludge discharge pipes. The efficiency of discharging the flocculation and the sludge is increased.

[0050] In some embodiments, the upper portion of the second reaction chamber 6 is provided with a clear water area. The annular inclined pipe 4 and the clear water area are communicated, and the water weir 7 and the clear water area are communicated. The clear water filtered by the annular inclined pipe 4 enters the clear water area and is discharged through the water weir 7.

[0051] In some embodiments, the second reaction chamber 6 is provided with a guide plate at the lower portion. The guide plate extends radially and downwardly from the outer peripheral wall of the throat pipe 1. When the flocculation and the sludge are settled, the flocculation and the sludge fall on the guide plate. The flocculation and the sludge are collected in the same part of the separation chamber 3 by the guide action of the guide plate, so that the flocculation and the sludge are conveniently discharged.

[0052] In some embodiments, the annular inclined pipe 4 comprises a plurality of inclined pipes which are connected side by side in a ring arrangement.

[0053] In the present embodiment, the plurality of inclined pipes are arranged such that the clear water flows through the inclined pipes when being discharged through the water outlet weir 7, and a small amount of impurities in the clear water adhere to the wall surface of the inclined pipe when passing through the annular inclined pipe 4, so that the impurities are separated from the clear water. The plurality of inclined pipes cooperate to increase or decrease the filtering effect and the filtering effect, thereby further improving the clarity of the clear water.

[0054] In some embodiments, the pipe diameter of the plurality of inclined pipes is 32 mm, which increases the adhesion of suspended solids in the clear water to the wall surface of the inclined pipe, thereby further improving the clarity of the clear water.

[0055] According to one embodiment of the present application, as shown in Figure 1 The included angle between the two side walls of the inverted V-shaped structure 18 is 120°-150°, which ensures that the floc and sludge settled at the bottom of the separation chamber 3 can be easily discharged, and also ensures the stability of the structure.

[0056] According to one embodiment of the present application, as shown in Figure 1 It further comprises a first tube sheet reactor 19, a second tube sheet reactor 20 and a third tube sheet reactor 21; the first tube sheet reactor 19, the second tube sheet reactor 20 and the third tube sheet reactor 21 are arranged from top to bottom along the water outlet port of the throat pipe 1, and the first tube sheet reactor 19, the second tube sheet reactor 20 and the third tube sheet reactor 21 are all located in the first reaction chamber 5 of the throat pipe.

[0057] In the present embodiment, the plurality of tube sheet reactors separate the first reaction chamber 5 into a plurality of regions, so that after the sewage added with reagents enters the throat pipe 1, the sewage sequentially performs flocculation reaction in each region, thereby prolonging the time for the sewage to perform preliminary flocculation reaction in the first reaction chamber 5, increasing the rapid flocculation reaction of the sewage, and increasing the flocculation reaction efficiency of the sewage.

[0058] According to one embodiment of the present application, as shown in Figure 1 It further comprises a fourth tube sheet reactor 22, a fifth tube sheet reactor 23 and a sixth tube sheet reactor 24, which are arranged in sequence from the water inlet end of the second reaction chamber 6 to the water outlet end of the second reaction chamber 6.

[0059] In the embodiment, the plurality of tube plate reactors are arranged to divide the second reaction chamber 6 into a plurality of areas, so that after the sewage in the first reaction chamber 5 enters the second reaction chamber 6, the sewage sequentially performs flocculation reaction in each area, the time for the sewage to perform secondary flocculation reaction in the second reaction chamber 6 is prolonged, the sewage quickly generates flocculation reaction is increased, and the flocculation reaction efficiency of the sewage is increased.

[0060] According to one embodiment of the present application, as shown in Figure 1 The tube plate reactor comprises a partition plate, a plurality of through holes and a plurality of pipes are distributed on the partition plate, the plurality of pipes are connected with the partition plate, and the plurality of pipes extend towards the bottom of the filter, the plurality of pipes correspond to the plurality of through holes respectively, the pipes and the through holes are in communication, the pipe diameter of the pipes is equal to the hole diameter of the through holes, and the partition plate is fixedly connected with the inner side wall of the first reaction chamber of the throat pipe.

[0061] In the embodiment, the partition plate has the effects of reducing the water flow amount and prolonging the flocculation reaction time of the sewage, and has the effect of increasing the water flow rate, thereby increasing the flocculation reaction of the sewage quickly. The partition plate has the effect of collecting water due to the pipes, thereby increasing the flow rate of the sewage through the through holes.

[0062] According to one embodiment of the present application, the plurality of through holes have a hole diameter R, and R>25mm.

[0063] In the embodiment, the tube plate reactor with a small through hole diameter has a fast water flow rate, and the through hole diameter R>25mm is arranged to ensure that the flocculation reaction of the sewage can pass through the through holes. In actual sewage treatment sites, the maximum length of the formed flocculation is generally less than 10mm, so the through hole of the embodiment can ensure that the flocculation can pass through in the case of increasing the water flow rate.

[0064] According to one embodiment of the present application, the through hole diameters of the first tube plate reactor 19, the second tube plate reactor 20 and the third tube plate reactor 21 are R1, R2 and R3 respectively.

[0065] R2>R1, R2>R3, R1<R3 or R1=R3.

[0066] Specifically, R1 is 25mm-32mm, R2 is 50mm-75mm, and R3 is 32mm-40mm.

[0067] In the embodiment, the through-hole aperture relationship among the first tube sheet reactor 19, the second tube sheet reactor 20 and the third tube sheet reactor 21 is such that the water flow rate changes in the form of fast-slow-fast alternately when the water flow in the first reaction chamber 5 passes through the third tube sheet reactor 21, the second tube sheet reactor 20 and the first tube sheet reactor 19 in turn during the water flow rising, so as to improve the reaction time and reaction efficiency of the flocculation reaction of the sewage in the first reaction chamber 5.

[0068] According to one embodiment of the present application, the through-hole apertures of the fourth tube sheet reactor 22, the fifth tube sheet reactor 23 and the sixth tube sheet reactor 24 are R4, R5 and R6 in turn.

[0069] Wherein, R5 < R4, R5 < R6, R4 < R6 or R4 = R6.

[0070] Specifically, R4 is 40mm-50mm, R5 is 25mm-32mm and R6 is 50mm-75mm.

[0071] In the embodiment, the through-hole aperture relationship among the fourth tube sheet reactor 22, the fifth tube sheet reactor 23 and the sixth tube sheet reactor 24 is such that the water flow rate changes in the form of slow-fast-slow alternately when the water flow in the second reaction chamber 6 passes through the fourth tube sheet reactor 22, the fifth tube sheet reactor 23 and the sixth tube sheet reactor 24 in turn during the water flow falling, so as to improve the reaction time and reaction efficiency of the flocculation reaction of the sewage in the second reaction chamber 6.

[0072] According to one embodiment of the present application, as shown in Figure 1 the second reaction chamber 6 is provided with a baffle 2 at the bottom, the baffle 2 extends downward from the periphery of the bottom of the second reaction chamber 6, and the included angle between the baffle 2 and the outer wall of the second reaction chamber 6 is 140°-150°.

[0073] In the embodiment, the water flow direction of the second reaction chamber 6 can be guided by the baffle, so that the floc and sludge are settled at the bottom of the separation chamber 3, and are convenient to discharge.

[0074] According to one embodiment of the present application, as shown in Figure 1 the throat pipe 1 inlet port width is A, the throat pipe 1 height is B, the throat pipe 1 outlet port width is C, the first reaction chamber 5 width is D, the distance between the top of the throat pipe 1 and the top of the second reaction chamber 6 is E, and the separation chamber 3 height is F.

[0075] Wherein, A:B:C:D:E:F:G = 1:18-22:5-8:9-12:2-3:9-11:25-30.

[0076] In the embodiment, the sewage treatment speed is improved, the clarity of the clear water obtained after sewage treatment is improved, the compactness of the structure is further increased, and the reliability of the structure is improved through the relationship setting between the structures of the clarifier.

[0077] According to one embodiment of the application, the sludge discharge pipe 14 is provided with an automatic sludge discharge program, and when the sludge accumulation in the separation chamber 3 reaches a set liquid level, a sludge discharge response program is triggered to automatically discharge sludge.

[0078] In the embodiment, the sludge discharge program is arranged on the sludge discharge pipe 14, and when the floc and sludge accumulation reaches a certain liquid level, the sludge discharge response program is triggered to automatically discharge sludge, thereby increasing the effect of automatic sewage treatment. The sludge discharge valve on the sludge discharge pipe 14 is a quick-opening slow-closing sludge discharge valve, and the sludge discharge time is 10s-30s, which ensures that the amount of clear water discharged with the sludge is reduced during the sludge discharge process.

[0079] In a second aspect, as shown in Figure 2 The water purifier provided by the embodiment has the clarifier described above, and further comprises a cyclone reaction zone 15, a preliminary suspended clarification zone 16, and a sludge chamber 10.

[0080] The cyclone reaction zone 15 is inverted conical; and the preliminary suspended clarification zone 16 is arranged above the cyclone reaction zone 15.

[0081] The clarifier is arranged above the preliminary suspended clarification zone 16, and the clarifier is in communication with the preliminary suspended clarification zone 16 through the throat pipe 1.

[0082] The preliminary suspended clarification zone 16 is provided with a central cylinder 9, the lower part of the central cylinder 9 is in the shape of an inverted circular truncated cone, the central cylinder 9 extends downward into the cyclone reaction zone 15, and a central cylinder sludge discharge pipe 17 is arranged at the side near the bottom of the central cylinder 9, the central cylinder sludge discharge pipe 17 penetrates the conical surface of the cyclone reaction zone 15 and is connected to the sludge chamber 10, and the sludge chamber 10 is arranged around the lower part of the outer periphery of the cyclone reaction zone 15.

[0083] The bottom of the cyclone reaction zone 15 is provided with a water inlet main pipe 11.

[0084] When the embodiment is implemented, the primary suspension clarification zone 16 is arranged on the inverted cone-shaped cyclone reaction zone 15, the clarifier is arranged above the primary suspension clarification zone 16, the throat pipe 1 outside the clarifier is connected to the primary suspension clarification zone 16, so that the clarifier is communicated with the primary suspension clarification zone 16 through the throat pipe 1, and the central cylinder 9 is arranged in the center of the primary suspension clarification zone 16, the top of the central cylinder 9 is an open structure, the bottom of the central cylinder 9 is a closed structure, the lower part of the central cylinder 9 is an inverted circular platform, the central cylinder 9 extends downward into the cyclone reaction zone 15, and the central cylinder 9 is provided with a central cylinder sludge discharge pipe 17 near the bottom of the side surface, the central cylinder sludge discharge pipe 17 penetrates the conical surface of the cyclone reaction zone 15 and is communicated with the sludge chamber 10, the sludge chamber 10 is arranged around the outer periphery of the lower part of the cyclone reaction chamber, and the water inlet main pipe 11 is connected to the bottom of the cyclone reaction zone 15.

[0085] The sewage added with the medicament enters the cyclone reaction zone 15 through the water inlet main pipe 11. Since the cyclone reaction zone 15 is an inverted cone structure, the sewage entering the cyclone reaction zone 15 rises in the cyclone reaction zone 15 in a cyclone flow mode, forms an agitating mode, so that the sewage is mixed with the medicament in the process of cyclone, the sewage and the medicament are flocculated, the separated impurities enter the central cylinder 9, and the sewage continues to rise to the primary suspension clarification zone 16, and then enters the clarifier through the throat pipe 1. The clarifier further clarifies the sewage to improve the purification effect of the clean water. The impurities falling in the central cylinder 9 are discharged through the central cylinder sludge discharge pipe 17 and fall into the sludge chamber 10.

[0086] In the embodiment, the cyclone reaction zone 15 and the clarifier cooperate, the sewage is subjected to the first-stage flocculation reaction in the cyclone reaction zone 15, then is subjected to the second-stage flocculation reaction in the first reaction chamber 5 of the clarifier, is subjected to the third-stage flocculation reaction in the second reaction chamber 6, and is filtered through the annular inclined pipe 4, so that the sewage is subjected to multiple procedures, the clarity of the clean water is improved, the sewage treatment in different stages is simultaneously performed, the continuous purification of the sewage is realized, and the work efficiency of the sewage purification is improved. The clarifier is arranged above the cyclone reaction zone 15, the integration of the structure is increased, and the area occupied by the clarifier is reduced. The sludge chamber 10 is used for collecting the impurities, so that the impurities generated in the flocculation reaction do not enter the clarifier with the sewage.

[0087] In the embodiment, in the water purifier structure provided with the clarifier, when the sewage enters the primary suspension clarification zone 16, the sewage is in contact with the bottom of the clarifier in the process of slowly rising, the bottom of the clarifier is an inverted V-shaped structure 18, the cross-sectional area of the bottom of the clarifier gradually decreases, the rising speed is accelerated, and the sewage enters the throat pipe at a faster speed. When the water purifier device is in a state of being filled with water, the inverted V-shaped structure 18 of the bottom of the clarifier bears more stress of the gravity of water, prevents the device from being deformed, and increases the reliability of the structure of the device.

[0088] In the present embodiment, the water purifier can treat sewage with high turbidity of 2000-5000 NTU, and the structure below the clarifier of the water purifier can reduce the turbidity of the sewage to 100-300 NTU. The sewage enters the first reaction chamber 5, the second reaction chamber 6 and the annular inclined pipe 4 in the clarifier for sewage treatment, so that the turbidity of the treated clear water can reach ≤3 NTU.

[0089] In some embodiments, the bottom of the central cylinder 9 is a tilted structure with high center and low periphery, facilitating the collection and discharge of impurities.

[0090] According to one embodiment of the present application, as shown in Figure 2 The top of the sludge chamber 10 is provided with a supernatant discharge port 13, and the bottom is provided with a sludge discharge valve 12.

[0091] In the present embodiment, the top of the central cylinder 9 is open, so that part of the sewage enters the central cylinder 9 along with the impurities. The sewage flows into the sludge chamber 10 along with the impurities through the central cylinder sludge discharge pipe 17 on the central cylinder 9. The impurities settle at the bottom of the sludge chamber 10, and the sewage and the impurities are separated. The sewage rises and is discharged from the supernatant discharge port 13, and the impurities are discharged through the control of the sludge discharge valve 12. The sewage has undergone a flocculation reaction once, and the impurities have been separated in the sludge chamber 10, so the sewage is preliminarily purified and can be used in applications with low requirements for clear water clarity.
