Description

Technical Field

[0001] The present application relates to the technical field of scale inhibition equipment, and in particular to a scale inhibition device for evaporating concentrated liquid of landfill leachate. Background Art

[0002] Evaporation of landfill leachate concentrate is an effective treatment process, mainly used to treat landfill leachate membrane concentrate produced by nanofiltration and reverse osmosis processes. During the evaporation of landfill leachate concentrate, a scale inhibitor is usually installed on the water inlet end of the evaporative heat exchanger. Before the landfill leachate concentrate enters the evaporator, the scale inhibitor removes or shields mineral ions such as calcium and magnesium in the landfill leachate concentrate to reduce the possibility of scale formation.

[0003] At present, the core chip of the existing scale inhibitor is made of an alloy material composed of nine metals. When the fluid flows through the alloy surface, free electrons are released, causing the fluid to polarize, shielding calcium ions and reducing the possibility of calcium sulfate precipitation and adhesion.

[0004] As the scale inhibitor is continuously used, it needs to be maintained to reduce the amount of scale and other impurities in the scale inhibitor. However, during maintenance, the scale inhibitor needs to be disassembled and removed, and then installed and fixed after maintenance, which affects the stable operation of the evaporator. Summary of the invention

[0005] In order to facilitate the maintenance of the scale inhibitor, the present application provides a garbage leachate concentrate evaporation scale inhibition device.

[0006] The present application provides a garbage leachate concentrate evaporation and scale prevention device, which adopts the following technical solution: A garbage leachate concentrate evaporation and scale prevention device, comprising A scale-inhibiting pipe is formed with a scale-inhibiting cavity, a liquid inlet pipe and a liquid outlet pipe communicating with the scale-inhibiting cavity are respectively arranged on both sides of the scale-inhibiting pipe, and a mounting column is arranged in the scale-inhibiting pipe; An alloy chip is arranged on the mounting column, the alloy chips are multiple and evenly spaced, and multiple water holes are evenly spaced on the alloy chip; A locking assembly, disposed on the mounting post, wherein the locking assembly locks the alloy chip; A rotating ring, rotatably connected to the scale-inhibiting pipe, the rotating ring is rotatably sleeved on the outer peripheral side of the alloy core sheet and slidably connected, and there are a plurality of rotating rings corresponding to the alloy core sheets one by one; An annular water delivery trough is formed in the rotating ring, and a plurality of water ejection holes facing the end surfaces of both sides of the alloy core are formed on the inner peripheral side wall of the rotating ring, and the water ejection holes are connected with the water delivery trough; A water delivery ring is arranged in the scale prevention pipe, and the water delivery ring is coaxially arranged with the rotating ring and is rotatably connected; The water delivery ring is formed with an annular water supply groove, the rotating ring is formed with a connecting hole connecting the water delivery groove and the annular water supply groove, and connecting pipes connecting the annular water supply groove are arranged between adjacent water delivery rings; A feed pipe, arranged on the outer wall of the scale inhibition pipe and close to the liquid inlet pipe, the feed pipe being connected with the connecting pipe; A discharge pipe is arranged on the outer wall of the scale inhibition pipe and close to the liquid outlet pipe, and the discharge pipe is connected with the scale inhibition chamber; A circulation pump is arranged on the outer peripheral side of the scale inhibition pipe, a liquid suction pipe connected to the scale inhibition chamber and close to the liquid outlet pipe is arranged on the water inlet side of the circulation pump, and a circulation pipe connected to the connecting pipe is arranged on the water outlet side of the circulation pump; The transmission assembly is arranged on the scale-inhibiting pipe. When the liquid suction pipe sucks liquid, the transmission assembly drives the rotating ring to rotate.

[0007] By adopting the above technical solution, the alloy chip in the scale inhibition tube evenly distributes the concentrated liquid of the landfill leachate through the water holes. When the concentrated liquid of the landfill leachate flows through the alloy surface, it releases free electrons, polarizes the fluid, shields calcium ions, and reduces the possibility of calcium sulfate precipitation and adhesion. During cleaning, the cleaning agent is introduced into the feed pipe, and the rotating design of the rotating ring, combined with the water injection hole, can spray the cleaning agent to dynamically flush the surface of the alloy chip and clean the scale on the surface of the alloy chip. At the same time, the design of the circulating pump and the connecting pipe allows the cleaning agent in the scale inhibition chamber to circulate and reuse the cleaning agent. The transmission assembly automatically drives the rotating ring to rotate according to the liquid absorption situation to achieve intelligent control. The entire cleaning process is simple, and there is no need to disassemble and remove the scale inhibition tube, which greatly facilitates the maintenance of the scale inhibitor.

[0008] Optionally, the transmission assembly includes a transmission blade, a transmission shaft, a transmission gear and a transmission rack; A receiving groove connected to the liquid suction pipe is formed in the anti-scaling pipe, the transmission shaft is rotatably connected to the anti-scaling pipe and extends into the receiving groove, and the transmission shaft extends to face the rotating ring; There are a plurality of transmission blades which are evenly spaced and arranged on the outer circumference of the transmission shaft, and the transmission blades extend into the liquid inlet pipe; The transmission rack is arranged on the outer peripheral side of the rotating ring, and the transmission gear is arranged on the outer peripheral side of the transmission shaft. The transmission gear is meshed with the transmission rack and corresponds to each other one by one.

[0009] By adopting the above technical solution, the transmission assembly includes a transmission blade, a transmission shaft, a transmission gear and a transmission rack. The design makes it possible for the cleaning agent to impact the transmission blade when it enters the scale-blocking tube through the liquid inlet pipe, driving the transmission shaft and the transmission gear to rotate. The meshing action of the transmission gear and the transmission rack causes the rotating ring to rotate accordingly. This design not only realizes the automatic drive of the rotating ring, but also can automatically adjust the rotation speed according to the size of the liquid inlet flow, thereby more effectively flushing the surface of the alloy chip and reducing the amount of scale on the surface of the alloy chip.

[0010] Optionally, the water jetting direction of the water jetting hole is perpendicular to the central axis of the alloy core chip, and the water jetting hole is adjacent to the alloy core chip.

[0011] By adopting the above technical solution, the design of the water jet hole enables the water delivery groove in the rotating ring to spray water to the end faces of both sides of the alloy chip, and the water jet direction is perpendicular to the central axis of the alloy chip. This design can ensure that the water flow can flush the surface of the alloy chip evenly and forcefully, effectively reducing the deposition of scale on the alloy chip. At the same time, the setting of the water jet hole near the alloy chip makes the flushing effect more direct and effective, increases the flushing area, and further improves the scale prevention effect.

[0012] Optionally, the rotating ring is inclined toward the alloy core sheet to form a flushing hole, the flushing hole and the water ejection hole are arranged alternately with each other, and the flushing hole is connected to the water delivery trough.

[0013] By adopting the above technical solution, the flushing holes and the water ejection holes are arranged alternately on the rotating ring, and the flushing holes are inclined toward the direction of the alloy chip. This design not only increases the amount and direction of water flow that flushes the surface of the alloy chip, but also allows the water flow to impact the surface of the alloy chip at a certain angle through the inclined flushing holes, further enhancing the flushing effect. The cooperation of the flushing holes and the water ejection holes allows the scale on the surface of the alloy chip to be flushed away more thoroughly.

[0014] Optionally, the liquid inlet pipe and the liquid outlet pipe are respectively provided with an opening and closing valve.

[0015] By adopting the above technical solution, the liquid inlet pipe and the liquid outlet pipe are respectively provided with an opening and closing valve, so that the inlet and outlet of the concentrated liquid of the garbage leachate can be controlled at any time as needed. When the scale prevention pipe needs to be cleaned or maintained, the liquid inlet pipe and the liquid outlet pipe can be closed to cut off the flow of the concentrated liquid of the garbage leachate, ensuring safe operation. At the same time, the design of the opening and closing valve also facilitates troubleshooting and maintenance of the device, thereby improving the reliability and stability of the device.

[0016] Optionally, the water through hole extends along an inclined direction.

[0017] By adopting the above technical solution, the design of the water holes on the alloy chip extending in an inclined direction can change the flow direction of the cleaning agent, so that the cleaning agent can produce a turbulent effect when passing through the alloy chip, thereby increasing the flushing force of the cleaning agent. This design not only helps to reduce the possibility of scale deposition on the alloy chip, but also can more effectively flush away the scale that has already formed, thereby improving the scale inhibition effect. At the same time, the inclined water holes can also increase the coverage rate of the cleaning agent on the surface of the alloy chip, ensuring that the entire surface of the alloy chip can be fully flushed.

[0018] Optionally, the locking assembly is a locking nut and a locking sleeve, the locking sleeve is slidably sleeved on the outer peripheral side of the mounting column, and there are multiple locking sleeves located between adjacent alloy core pieces; The locking nuts are threadedly connected to the mounting posts, and the locking nuts are symmetrically arranged and respectively abut against the outermost alloy core sheets.

[0019] By adopting the above technical solution, the locking assembly includes a locking nut and a locking sleeve, which are designed to firmly lock the position of the alloy chip on the mounting column, reducing the possibility of the alloy chip loosening or falling off under the flushing of the concentrated leachate. The design of the locking nuts being symmetrically arranged and respectively abutting against the outermost alloy chips ensures the close arrangement and stable fixation of the alloy chips. At the same time, the design of the locking sleeve slidingly sleeved on the outer peripheral side of the mounting column enables the locking assembly to be flexibly adjusted according to the number and position of the alloy chips, thereby improving the applicability and flexibility of the device.

[0020] Optionally, the anti-scaling pipe includes a pipe cover and a pipe body, and the pipe cover is symmetrically arranged and threadedly connected to both ends of the pipe body respectively; The liquid inlet pipe and the liquid outlet pipe are respectively arranged opposite to the pipe cover, and two ends of the mounting column are respectively pressed against the pipe cover.

[0021] By adopting the above technical solution, the design of the pipe cover being symmetrically arranged and respectively threadedly connected to the two ends of the pipe body is not only convenient for disassembly and installation, but also can ensure the sealing of the scale-proof chamber and reduce the possibility of leakage of the concentrated liquid of the garbage leachate. At the same time, the design of the two ends of the mounting column respectively pressing against the pipe cover enables the alloy chip and the locking assembly to be firmly fixed in the scale-proof pipe, thereby improving the stability and reliability of the scale-proof device. In addition, the design of the pipe cover and the pipe body also facilitates the cleaning and maintenance of the scale-proof chamber, thereby extending the service life of the scale-proof device.

[0022] In summary, the present application includes at least one of the following beneficial effects: 1. The cleaning agent is introduced into the feed pipe, and the rotating design of the rotating ring, in conjunction with the water jet hole, can spray out the cleaning agent, dynamically flush the surface of the alloy chip, and clean the scale on the surface of the alloy chip. At the same time, the design of the circulation pump and the connecting pipe allows the cleaning agent in the scale inhibition chamber to circulate and be reused. The entire cleaning process is simple, and there is no need to disassemble and remove the scale inhibition tube, which greatly facilitates the maintenance of the scale inhibitor; 2. The flushing holes and water injection holes are staggered on the rotating ring, and the flushing holes are inclined toward the alloy chip. This design not only increases the amount and direction of water flow that flushes the surface of the alloy chip, but also through the inclined flushing holes, the water flow can impact the surface of the alloy chip at a certain angle, further enhancing the flushing effect.
