Abstract
Description
Technical Field
[0001] This invention relates to the field of wastewater treatment technology, and more specifically to a self-cleaning wastewater treatment device. Background Technology
[0002] Industrial production generates large amounts of high-salinity wastewater. Direct discharge of this wastewater would cause significant environmental pollution and would not meet my country's zero-discharge requirements for high-salinity wastewater. High-salinity wastewater treatment is among the most challenging wastewater treatment methods, primarily because highly concentrated brine readily crystallizes. Consequently, current hot flue gas drying processes suffer from crystallization and scaling problems, severely impacting equipment stability and output. This limits the widespread adoption of hot flue gas-based high-salinity wastewater treatment devices.
[0003] Therefore, there is an urgent need for a self-cleaning wastewater treatment device to solve the above problems. Summary of the Invention
[0004] The purpose of this invention is to solve the problem that crystallization and scaling in existing high-salt wastewater treatment devices based on hot flue gas affect the stable operation and output of the equipment, and to provide a self-cleaning wastewater treatment device.
[0005] To achieve the above objectives, the present invention provides a self-cleaning wastewater treatment device, which includes a cylinder, a drive mechanism, a water supply pipeline, a smoke supply pipeline, and an outlet pipeline.
[0006] The driving mechanism is used to drive the cylinder to rotate, the water supply pipeline is used to supply water into the cylinder, the smoke supply pipeline is used to introduce flue gas into the cylinder through the inlet, the outlet pipeline is connected to the outlet of the cylinder and has a number of airfoil blades inside, and the cylinder is provided with abrasive.
[0007] Preferably, a plurality of vertical ribs for lifting the abrasive are provided at intervals on the inner surface of the cylinder, and the height of the vertical ribs is 1%-5% of the radius of the cylinder.
[0008] Preferably, the included angle between adjacent vertical ribs on the inner surface of the cylinder is 10°-45°.
[0009] Preferably, the upright rib is provided with a plurality of protrusions.
[0010] Preferably, the airfoil blades in the outlet pipe are arranged in an alternating manner.
[0011] Preferably, the abrasive comprises steel balls, zirconium oxide, fly ash, and slag.
[0012] Preferably, the driving mechanism includes a ball bearing wheel and a motor for driving the ball bearing wheel to rotate; the inlet end of the cylinder is rotatably connected to the roller inside the first ball bearing wheel, the smoke outlet end of the smoke conveying pipe is connected to the non-rotating part of the first ball bearing wheel, the outlet end of the cylinder is rotatably connected to the roller inside the second ball bearing wheel, the outlet pipe is connected to the outlet of the cylinder through the non-rotating part of the second ball bearing wheel, and the water outlet end of the water conveying pipe extends into the cylinder through the smoke conveying pipe.
[0013] Preferably, the surface of the ball bearing wheel is provided with chain teeth, and the motor drives the cylinder to rotate through the chain teeth via the chain and sprocket, with the cylinder rotating at a speed of 10-25 revolutions per minute.
[0014] Preferably, the airfoil blade is an arc-shaped blade.
[0015] Preferably, the airfoil blade is made of a wear-resistant material, including wear-resistant steel.
[0016] According to the above technical solution, based on this self-cleaning wastewater treatment device, in practical applications, the treatment efficiency of high-salt wastewater can be effectively improved through the combined action of the cylinder, drive mechanism, water supply pipeline, smoke supply pipeline and outlet pipeline, and scale will not form inside the cylinder and airfoil blades, thereby ensuring that the wastewater treatment device can continuously and efficiently treat high-salt wastewater.
[0017] Meanwhile, a number of vertical ribs for lifting the abrasive are provided at intervals on the inner surface of the cylinder. The height of the vertical ribs is 1%-5% of the radius of the cylinder. The included angle between adjacent vertical ribs on the inner surface of the cylinder is 10°-45°. The vertical ribs are provided with a number of protrusions. In practical applications, this can further improve the treatment efficiency of high-salt wastewater and prevent scaling inside the cylinder, thereby ensuring the sustainable and efficient operation of the wastewater treatment equipment.
[0018] The outlet pipe has several airfoil blades arranged in an alternating pattern. These airfoil blades are arc-shaped and can effectively capture incompletely vaporized droplets carried by the high-temperature flue gas, allowing them to continue to crystallize. When the flue gas containing crystalline powder in the cylinder passes through the several airfoil blades arranged in an alternating pattern, it can erode and pulverize the crystals on the airfoil blades, thus achieving self-cleaning of the airfoil blades.
[0019] By using abrasives including steel balls, zirconium oxide, fly ash, and slag, the efficiency of wastewater treatment can be further improved and scale formation inside the cylinder can be prevented. Attached Figure Description

[0028] This invention provides a self-cleaning wastewater treatment device, such as... Figure 1-2 As shown, the self-cleaning wastewater treatment device includes a cylinder 1, a drive mechanism, a water supply pipeline 6, a smoke supply pipeline 8, and an outlet pipeline 9.
[0029] The driving mechanism is used to drive the cylinder 1 to rotate, the water supply pipe 6 is used to supply water into the cylinder 1, the smoke supply pipe 8 is used to supply flue gas into the cylinder 1 through the inlet 4, the outlet pipe 9 is connected to the outlet 5 of the cylinder 1 and is provided with a number of airfoil blades 10, and the cylinder 1 is provided with abrasive 3.
[0030] In a preferred embodiment, the abrasive 3 includes steel balls, zirconium oxide, fly ash, and slag, which can further improve the wastewater treatment efficiency and ensure that no scale forms inside the cylinder 1.
[0031] According to the above technical solution, based on this self-cleaning wastewater treatment device, in practical applications, the treatment efficiency of high-salt wastewater can be effectively improved through the combined action of the cylinder, drive mechanism, water supply pipeline, smoke supply pipeline and outlet pipeline, and scale will not form inside the cylinder and airfoil blades, thereby ensuring that the wastewater treatment device can continuously and efficiently treat high-salt wastewater.

[0035] In a further preferred embodiment, the vertical rib 2 is provided with a plurality of protrusions.
[0036] In this invention, by further providing a plurality of vertical ribs 2 at intervals on the inner surface of the cylinder 1 for lifting the abrasive 3, and making the height of the vertical ribs 2 1%-5% of the radius of the cylinder 1, and the included angle between adjacent vertical ribs 2 on the inner surface of the cylinder 1 10°-45°, and by providing a plurality of protrusions on the vertical ribs 2, the treatment efficiency for high-salt wastewater can be effectively improved in practical applications, and scale will not form inside the cylinder 1, thereby ensuring the sustainable and efficient operation of the wastewater treatment equipment. In one specific embodiment, the number of vertical ribs 2 provided inside the cylinder 1 can be set according to the size of the cylinder 1 and the need for anti-scaling inside the cylinder 1. Similarly, the number of protrusions on the vertical ribs 2 can be set according to the size of the vertical ribs 2 and the need for anti-scaling inside the cylinder 1.
[0037] In the self-cleaning wastewater treatment device of the present invention, preferably, a plurality of airfoil blades 10 in the outlet pipe 9 are staggered, and the airfoil blades 10 are arc-shaped blades. By further staggering and arranging the plurality of airfoil blades 10 in an arc shape, the incompletely vaporized droplets carried by the high-temperature flue gas can be more effectively captured, allowing them to continue to crystallize. Furthermore, when the flue gas containing crystalline powder in the cylinder 1 passes through the staggered airfoil blades 10, the crystals on the airfoil blades 10 can be eroded and pulverized, achieving self-cleaning of the airfoil blades 10. Moreover, by further using a wear-resistant material, including wear-resistant steel, the service life of the airfoil blades 10 can be effectively extended.
[0038] In the self-cleaning wastewater treatment device of the present invention, in a preferred embodiment, the driving mechanism includes a ball bearing wheel 7 and a motor for driving the ball bearing wheel 7 to rotate; wherein, the ball bearing wheel 7 may be, for example, a ball bearing.
[0039] The inlet end of the cylinder 1 is rotatably connected to the roller inside the first ball bearing wheel 7. The smoke outlet end of the smoke conveying pipe 8 is connected to the non-rotating part of the first ball bearing wheel 7. The outlet end of the cylinder 1 is rotatably connected to the roller inside the second ball bearing wheel 7. The outlet pipe 9 is connected to the outlet 5 of the cylinder 1 through the non-rotating part of the second ball bearing wheel 7. The water outlet end of the water conveying pipe 6 extends into the cylinder 1 through the smoke conveying pipe 8.
[0040] In one specific embodiment, the surface of the ball bearing wheel 7 is provided with chain teeth, and the motor drives the cylinder 1 to rotate through the chain teeth via the chain and sprocket. The rotational speed of the cylinder 1 is 10-25 revolutions per minute.
[0041] In this invention, by rotatably connecting the inlet end of the cylinder 1 to the roller inside the first ball bearing wheel 7, connecting the smoke-conducting end of the smoke-conducting pipe 8 to the non-rotating part of the first ball bearing wheel 7, rotatably connecting the outlet end of the cylinder 1 to the roller inside the second ball bearing wheel 7, and connecting the outlet pipe 9 to the outlet 5 of the cylinder 1 through the non-rotating part of the second ball bearing wheel 7, the smoke-conducting pipe 8 and the outlet pipe 9 remain stationary when the motor synchronously drives the two ball bearing wheels 7 at the inlet and outlet ends of the cylinder 1 to rotate, thereby driving the cylinder 1 to rotate at a set speed. Furthermore, the water-conducting pipe 6 is set based on the stationary smoke-conducting pipe 8, and the outlet end of the water-conducting pipe 6 extends into the interior of the cylinder 1, thus achieving water delivery without affecting the rotation of the cylinder 1. Of course, the cylinder 1, the driving mechanism, the water-conducting pipe 6, the smoke-conducting pipe 8, and the outlet pipe 9 can also be installed and connected in other ways, as long as they have the same function.
[0042] The present invention will be described in detail below through embodiments, but the scope of protection of the present invention is not limited thereto.
[0043] Example 1
[0044] Adopting such Figure 1 The self-cleaning wastewater treatment device shown is implemented as follows: Specifically, the self-cleaning wastewater treatment device includes a cylinder 1, a drive mechanism, a water supply pipeline 6, a smoke supply pipeline 8, and an outlet pipeline 9.
[0045] The driving mechanism is used to drive the cylinder 1 to rotate, the water supply pipe 6 is used to supply water into the cylinder 1, the smoke supply pipe 8 is used to introduce flue gas into the cylinder 1 through the inlet 4, the outlet pipe 9 is connected to the outlet 5 of the cylinder 1 and is provided with a plurality of airfoil blades 10, and the cylinder 1 is provided with abrasive 3; the abrasive 3 is fly ash.
[0046] The driving mechanism includes a ball bearing wheel 7 and a motor for driving the ball bearing wheel 7 to rotate; the surface of the ball bearing wheel 7 is provided with chain teeth, and the motor drives the cylinder 1 to rotate through the chain teeth via a chain and a sprocket; the inlet end of the cylinder 1 is rotatably connected to the roller inside the first ball bearing wheel 7, the smoke outlet end of the smoke conveying pipe 8 is connected to the non-rotating part of the first ball bearing wheel 7, the outlet end of the cylinder 1 is rotatably connected to the roller inside the second ball bearing wheel 7, the outlet pipe 9 is connected to the outlet 5 of the cylinder 1 through the non-rotating part of the second ball bearing wheel 7, and the water outlet end of the water conveying pipe 6 extends into the cylinder 1 through the smoke conveying pipe 8.
[0047] In practical applications, high-temperature flue gas is fed into cylinder 1 through inlet 4 via flue gas pipeline 8, while high-salt wastewater is fed into cylinder 1 through water pipeline 6. The motor is started, driving cylinder 1 to rotate at 15 rpm via two ball bearing rollers 7. This causes the low-heat-capacity abrasive 3 inside cylinder 1 to rise, exchanging heat with the high-temperature flue gas. The high-salt wastewater turns into steam, and salt crystals precipitate. Simultaneously, due to mutual collision and friction, the low-heat-capacity abrasive 3 precipitates within cylinder 1 and interacts with the high-temperature flue gas. The crystalline salt powder on the surface of the cylinder 1 is carried by the hot flue gas into the airfoil blades 10 in the outlet pipe 9. The incompletely vaporized water droplets formed by the collision in the cylinder 1 are captured by the airfoil blades 10 and vaporized by heat exchange on the upper surface of the airfoil blades 10 to form a crystalline layer. When the crystalline powder pulverized in the cylinder 1 is carried into the airfoil blades 10 by the high temperature hot flue gas, the powder abrades the airfoil blades 10, and the crystalline layer on the surface of the airfoil blades 10 is abraded into powder, which is discharged from the outlet with the high temperature hot flue gas.

At the same time, it has good applicability even when the high-temperature flue gas contains dust.
[0049] Example 2
[0050] Referring to Embodiment 1, the difference is that a plurality of vertical ribs 2 for lifting the abrasive 3 are provided at intervals on the inner surface of the cylinder 1. The height of the vertical ribs 2 is 3% of the radius of the cylinder 1. The included angle between adjacent vertical ribs 2 on the inner surface of the cylinder 1 is 25°. A plurality of protrusions are provided on the vertical ribs 2.
[0051] Testing has shown that the self-cleaning wastewater treatment device described in this invention, through the combined action of the cylinder, drive mechanism, water supply pipeline, flue gas supply pipeline, and outlet pipeline, can more effectively improve the treatment efficiency of high-salt wastewater, and will not cause scaling inside the cylinder and airfoil blades, thereby ensuring that the wastewater treatment device can continuously and efficiently treat high-salt wastewater. At the same time, it has good applicability even when the high-temperature flue gas contains dust.
[0052] Example 3
[0053] The implementation is similar to Embodiment 2, except that a plurality of airfoil blades 10 are staggered in the outlet pipe 9. The airfoil blades 10 are arc-shaped blades and are made of wear-resistant materials, including wear-resistant steel.
[0054] Testing has shown that the self-cleaning wastewater treatment device described in this invention, through the combined action of the cylinder, drive mechanism, water supply pipeline, flue gas supply pipeline, and outlet pipeline, can more effectively improve the treatment efficiency of high-salt wastewater, and will not cause scaling inside the cylinder and airfoil blades, thereby ensuring that the wastewater treatment device can continuously and efficiently treat high-salt wastewater.
