Description

Technical Field

[0001] This invention relates to the field of saline-alkali land management, and more specifically, to an improved device and process for saline-alkali land management. Background Technology

[0002] Saline-alkali land is a global ecological problem that severely restricts agricultural production and ecological balance. Traditional treatment technologies, such as leaching and chemical remediation, suffer from problems such as large-scale engineering, high costs, and the potential for secondary pollution, and their application is limited, especially in water-scarce areas. In recent years, physical adsorption methods have gained attention due to their environmental advantages.

[0003] Existing improvement devices generally suffer from low adsorption efficiency, easy material saturation, and salt retention, affecting the treatment effect. Most saline-alkali water treatment equipment uses a single-layer filtration structure, resulting in a short water flow path and insufficient contact time between the ion exchange material and the water, leading to unstable desalination rates. Simultaneously, the drainage system lacks a slow-flow design, easily causing soil erosion and secondary salt accumulation. Therefore, this paper proposes an improvement device and process for saline-alkali land treatment. Summary of the Invention

[0004] The purpose of this invention is to address the problems of low adsorption efficiency, easy material saturation, and salt retention that are common in existing devices, which affect the treatment effect. Most saline-alkali water treatment equipment adopts a single-layer filtration structure, which results in a short water flow path and insufficient contact time between the ion exchange material and the water, leading to unstable desalination rate. At the same time, the drainage system lacks a slow-flow design, which can easily cause soil erosion and secondary salt accumulation.

[0005] To achieve the aforementioned objectives, this invention provides the following technical solution: an improvement device for saline-alkali land treatment to address the aforementioned problems. Specifically, this invention includes a flow plate, a treatment component positioned below the flow plate, and a discharge component positioned below the treatment component.

[0006] The treatment assembly includes a drain hole, an extension pipe, an activated carbon layer, a vertical pipe, a spiral pipe, and a drain pipe. The drain hole is located at the top of the flow plate and extends to the bottom of the flow plate. The extension pipe is located below the flow plate. The activated carbon layer is located inside the extension pipe. The vertical pipe is located below the extension pipe. The spiral pipe is located inside the vertical pipe. The drain pipe is inserted below the vertical pipe. The top of the spiral pipe is located on one side of the activated carbon layer. The spiral pipe has pores with a diameter of 1-2 mm in its wall and is filled with ion exchange resin or biochar particles to adsorb salt ions in the flowing water.

[0007] As a preferred technical solution of the present invention, the discharge assembly includes a barrier fin and a through hole. The plurality of barrier fins are evenly distributed on the inner sidewall of the drain pipe, and the through hole is opened on one side of the barrier fin and extends to the other side of the barrier fin.

[0008] As a preferred technical solution of the present invention, the inner top of the flow plate is provided with an arc-shaped surface, and seepage grooves are provided on both sides of the flow plate, with the seepage grooves extending through to one side of the arc-shaped surface.

[0009] As a preferred technical solution of the present invention, a waterproof gasket is provided at the joint between the vertical pipe and the drain pipe, the bottom of the waterproof gasket is snapped into the top of the drain pipe, and the top of the waterproof gasket abuts against the bottom of the vertical pipe.

[0010] As a preferred embodiment of the present invention, reinforcing plates are provided on both sides of the vertical pipe, with one end of the reinforcing plate pointing downwards and the other end of the reinforcing plate located above the drain pipe.

[0011] As a preferred technical solution of the present invention, a guide groove is provided on one side of the arc-shaped surface, the bottom end of the guide groove is located on one side of the leakage hole, and the guide groove and the seepage groove are arranged alternately.

[0012] As a preferred technical solution of the present invention, the top of the flow plate is provided with a collection groove, the collection groove is located at the top of the leakage hole, and the collection groove is connected to the guide groove.

[0013] An improved process for saline-alkali land management employs the aforementioned improved device.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. Through the designed treatment components, the salt content in irrigation water or surface runoff is effectively reduced through a multi-layer purification mechanism. When water flows through the adsorption material, salt ions (such as sodium and chlorine) are selectively removed, reducing the risk of salt infiltrating into the soil and thus alleviating soil salinization. At the same time, the microporous structure regulates the water flow rate and the sufficiency of the adsorption reaction, ensuring stable desalination efficiency, providing low-salt irrigation water for saline-alkali land, improving soil permeability, and promoting salt leaching and the restoration of the plant root growth environment.

[0016] 2. The designed discharge components enable dynamic interception of residual salt crystals or soil particles, preventing secondary salt deposition or drainage system blockage. Turbulence and centrifugal effects prevent solidification, reducing the risk of salt crystal deposition and blockage in drainage pipes, maintaining unobstructed drainage channels, and ensuring continuous salt discharge.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Therefore, the following detailed description of embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely illustrates some embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] like Figure 1-2 As shown, this embodiment proposes an improvement device for saline-alkali land treatment, including a water flow plate 1, a treatment component 2 arranged below the water flow plate 1, and a discharge component 3 arranged below the treatment component 2.

[0028] like Figure 3-5As shown, the treatment component 2 includes a drain hole 201, an extension pipe 202, an activated carbon layer 203, a vertical pipe 204, a spiral pipe 205, and a drain pipe 206. The drain hole 201 is located at the top of the water flow plate 1 and extends to the bottom of the water flow plate 1. The activated carbon layer 203 is disposed inside the extension pipe 202, which is located below the water flow plate 1. The vertical pipe 204 is located below the extension pipe 202. The spiral pipe 205 is disposed inside the vertical pipe 204. The drain pipe 206 is inserted into the bottom of the vertical pipe 204. The top of the spiral pipe 205 is located on one side of the activated carbon layer 203. The wall of the spiral pipe 205 has micropores (pore diameter 1-2 mm) and is filled with ion exchange resin or biochar particles to adsorb salt ions in the flowing water. Surface water is collected through the drain hole 201 at the top of the water flow plate 1. When the water flows into the extension pipe 202, the activated carbon layer 203 adsorbs the salt ions in the water. The activated carbon layer 203 utilizes its porous structure and adsorption properties to adsorb salt ions in the flowing water, thereby performing preliminary desalination treatment on the saline water. The water flows through the extension pipe 202 and enters the spiral tube 205 inside the vertical pipe 204.

[0029] like Figure 3 As shown, the spiral tube 205 has 1-2 mm micropores on its wall and is filled with ion exchange resin or biochar particles to remove salt ions from the water using their adsorption properties. The purified water continues to flow down to the drain pipe 206 for discharge, thus achieving desalination of saline water. At the same time, the top of the spiral tube 205 is close to the activated carbon layer 203, which enhances the synergistic adsorption effect.

[0030] like Figure 4 As shown, the discharge assembly 3 includes barrier fins 301 and through holes 302. Multiple barrier fins 301 are evenly distributed on the inner wall of the drain pipe 206. The through holes 302 are opened on one side of the barrier fins 301 and extend to the other side. The barrier fins 301 evenly distributed on the inner wall of the drain pipe 206 and the through holes 302 form a multi-stage buffer structure. When water flows through, the fins and through holes 302 slow down the flow rate, prolonging the contact time between the water and the adsorbent material, improving salt interception efficiency, and preventing blockage of the drain pipe 206, ensuring orderly water discharge.

[0031] like Figure 1 As shown, the inner top of the water flow plate 1 is provided with an arc-shaped surface 4, and seepage grooves 5 are provided on both sides of the water flow plate 1. The seepage grooves 5 extend to one side of the arc-shaped surface 4. The arc-shaped surface 4 at the inner top of the water flow plate 1 and the seepage grooves 5 on both sides form a double flow guiding system. The arc-shaped surface 4 guides the water flow towards the center, while the seepage grooves 5 divert some water to the periphery of the drain hole 201 to prevent local water accumulation. The seepage grooves 5 extend to the side of the arc-shaped surface 4, allowing water to permeate evenly, thus achieving both efficient water collection and anti-siltation functions.

[0032] like Figure 3As shown, a waterproof gasket 6 is provided at the joint between the vertical pipe 204 and the drain pipe 206. The bottom of the waterproof gasket 6 is engaged with the top of the drain pipe 206, and the top of the waterproof gasket 6 abuts against the bottom of the vertical pipe 204, forming a two-way seal. This design prevents leakage at the joint, while also buffering the impact of water flow, ensuring a stable connection between the vertical pipe 204 and the drain pipe 206, and extending the service life of the device.

[0033] like Figure 3 As shown, reinforcing plates 7 are installed on both sides of the vertical pipe 204. One end of the reinforcing plate 7 points downwards and is located above the drainage pipe 206. The reinforcing plates 7 on both sides of the vertical pipe 204 extend downwards to above the drainage pipe 206, forming a triangular support structure. The reinforcing plates 7 enhance the overall resistance to deformation by dispersing the water flow pressure borne by the vertical pipe 204, making it particularly suitable for soft soil in saline-alkali areas and ensuring the long-term stability of the device.

[0034] like Figure 1 and Figure 3 As shown, a guide channel 8 is provided on one side of the arc-shaped surface 4. The bottom end of the guide channel 8 is located on one side of the leakage hole 201. The guide channel 8 and the seepage channel 5 are staggered. The guide channel 8 is added to one side of the arc-shaped surface 4, with its bottom end pointing towards the leakage hole 201, and is arranged in a staggered manner with the seepage channel 5. The guide channel 8 accurately guides the collected water to the leakage hole 201, while the staggered design avoids water flow path conflicts, improves water collection efficiency, and reduces the risk of sediment deposition in the guide channel 8.

[0035] like Figure 1 and Figure 3 As shown, a collecting trough 9 is provided on the top of the water flow plate 1. The collecting trough 9 is located above the drain hole 201 and is connected to the guide trough 8. The collecting trough 9 on the top of the water flow plate 1 is located directly above the drain hole 201 and is connected to the guide trough 8, forming a three-level water collection network. The collecting trough 9 concentrates water from a large area, while the guide trough 8 diverts the water in a directional manner, ensuring that the water efficiently flows into the drain hole 201, avoiding overflow caused by excessive flow, and optimizing the water resource recovery rate.

[0036] An improved process for saline-alkali land remediation employs the aforementioned improved device. Specifically, surface water first collects through the drainage hole 201 at the top of the water flow plate 1. Its arc-shaped surface 4 and the two side infiltration channels 5 form a dual flow guiding system: the arc-shaped surface 4 guides the water flow towards the center, while the infiltration channels 5 divert some water to the periphery of the drainage hole 201. This, combined with the three-stage water collection network formed by the top collection channel 9 and the guiding channel 8, ensures efficient and directional water flow while preventing overflow. After preliminary filtration through the activated carbon layer 203 in the extension pipe 202, the water enters the vertical pipe 204, where deep desalination is completed in the internal spiral tube 205. The spiral tube 205 has 1-2 mm micropores on its wall and is filled with ion exchange resin or biochar particles. Salt ions are removed through a dual mechanism of physical adsorption and ion exchange, and the synergistic effect between its top and the activated carbon layer 203 further enhances the adsorption efficiency. When the purified water enters the drain pipe 206 through the bottom of the vertical pipe 204, multiple sets of blocking fins 301 on the inner wall and through holes 302 form a multi-stage buffer structure, which not only prolongs the water-material contact time to improve desalination efficiency, but also prevents pipe blockage through flow rate control. In terms of device structure design, the vertical pipe 204 and the drain pipe 206 achieve bidirectional sealing and seepage prevention through the insertion of a waterproof gasket 6, and the reinforcing plates 7 on both sides form a triangular support structure to enhance overall stability, making it particularly suitable for the soft geological environment of saline-alkali land. The entire system achieves continuous and efficient desalination and stable discharge of saline-alkali water through three-stage treatment of water diversion and collection, adsorption and desalination, and buffer discharge, combined with reinforced design to prevent siltation, deformation, and leakage.

[0037] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
