Workshop dangerous chemical leakage cofferdam

Abstract

The application relates to a workshop dangerous chemical leakage cofferdam and relates to the technical field of chemical production safety protection, and comprises a cofferdam frame. The application solves the problems that a traditional cofferdam cannot actively adsorb, and an improved cofferdam has low adsorption efficiency and is prone to secondary pollution by arranging a honeycomb liquid absorption module. The honeycomb liquid absorption module is composed of an anticorrosion-treated regular hexagonal aluminum honeycomb core material and surface-modified non-woven fabric containing a functional group for targeted adsorption of dangerous chemicals. The surface-modified non-woven fabric is attached to the outer surface of the honeycomb core material and the inner wall of the honeycomb hole. When liquid dangerous chemicals leak and contact the module, the surface-modified non-woven fabric can actively adsorb the dangerous chemicals, and the honeycomb core material provides stable structural support for adsorption. Meanwhile, the side edges of the module are sealed and spliced through buckle type connecting pieces, so that liquid leakage from the splicing gap is avoided. The structure not only gets rid of the limitations of traditional cofferdams that only physically block and rely on manual cleaning, but also reduces the risk of liquid diffusion.

Description

Technical Field

[0001] This application relates to the field of safety protection technology in chemical production, and in particular to a containment dike for hazardous chemical leaks in a workshop. Background Technology

[0002] This utility model relates to the field of chemical production safety protection technology, specifically a workshop hazardous chemical leakage containment dike, which is applicable to places such as waterproof material production workshops and chemical plants where liquid hazardous chemicals are stored or used. In chemical production processes, leaks of liquid hazardous chemicals pose a significant safety hazard that urgently needs to be addressed. Currently, the industry's main protective equipment for hazardous chemical leaks is the traditional dike, which has obvious shortcomings: First, traditional concrete or metal dikes can only provide physical barriers and cannot actively absorb leaked liquids, requiring manual cleanup after a leak and easily leading to the risk of liquid spread; Second, although some improved dikes are filled with granular adsorbent materials (such as diatomaceous earth and activated carbon), their adsorption efficiency is low, and the adsorbent material is prone to escape after saturation, posing a secondary pollution problem; Third, existing dikes generally lack a directional flow guidance mechanism, allowing leaked liquids to accumulate inside the dike, which not only affects the adsorption effect but also increases the difficulty of subsequent treatment. Although industry standards clearly require hazardous chemical storage areas to be equipped with leakage emergency facilities, existing technologies are unable to simultaneously meet the three core requirements of rapid adsorption, directional flow guidance, and environmentally friendly recycling, and cannot effectively guarantee workshop production safety and the health of operators. Therefore, there is an urgent need for a workshop hazardous chemical leakage containment dike that can solve the above problems. Utility Model Content

[0003] The purpose of this application is to provide a workshop hazardous chemical leakage containment dike, which solves the problems of traditional containment dikes being unable to actively absorb liquids and the problems of low absorption efficiency and easy secondary pollution of improved containment dikes, and also solves the problems of existing containment dikes lacking a directional flow guidance mechanism and easy liquid accumulation.

[0004] This application provides a workshop hazardous chemical leakage containment dike with the following technical solution: It includes a dike frame, with honeycomb-shaped liquid-absorbing modules arranged in an array on the inner side of the frame to absorb leaked liquid hazardous chemicals; a flow-guiding channel system is provided at the bottom of the dike frame to receive the liquid discharged from the honeycomb-shaped liquid-absorbing modules and achieve directional transport; the dike frame provides installation support for the honeycomb-shaped liquid-absorbing modules and the flow-guiding channel system, and a connection structure for fixing it to the workshop floor is provided at the bottom of the dike frame; the honeycomb-shaped liquid-absorbing module is composed of a honeycomb core material and a surface-modified non-woven fabric composite, and snap-fit ​​connectors are provided on the sides of the honeycomb-shaped liquid-absorbing module for sealing and splicing multiple honeycomb-shaped liquid-absorbing modules. By adopting the above technical solution, honeycomb-shaped liquid absorption modules are arrayed inside the cofferdam frame. Utilizing the composite structure of the honeycomb core material and surface-modified non-woven fabric, the leaked liquid hazardous chemicals are actively adsorbed, overcoming the limitations of traditional cofferdams that only provide physical barriers and rely on manual cleaning, thus reducing the risk of liquid diffusion. The snap-fit ​​connectors' sealed splicing design prevents liquid leakage from the module gaps, improving the protective sealing performance. The diversion channel system can directionally transport the adsorbed liquid, solving the problem of liquid accumulation in existing cofferdams. The connection structure ensures the stable fixation of the cofferdam, and the overall structure achieves integrated "adsorption-diversion-fixation," effectively guaranteeing the protection effect against hazardous chemical leaks in the workshop.

The connection structure is set with expansion bolts, which can firmly penetrate the bottom of the frame and connect to the workshop ground, preventing the cofferdam from shifting during use, ensuring the structural stability during leakage protection, and further improving the safety of equipment use.

[0008] By adopting the above technical solution, the honeycomb core material is selected as a regular hexagonal aluminum honeycomb core material and is treated with anti-corrosion. While ensuring the lightweight structure, it improves the corrosion resistance and is suitable for hazardous chemical contact scenarios. The surface-modified non-woven fabric is attached to the outer surface of the core material and the inner wall of the honeycomb holes, increasing the contact area with the leaked liquid. The functional groups it contains that specifically adsorb hazardous chemicals can improve the adsorption efficiency and adsorption specificity, avoiding the problem of low efficiency of particulate adsorption materials in improved dikes, and preventing the release of loose materials and eliminating secondary pollution.

[0009] Preferably, the diversion channel system includes a main channel body, a branch pipe, and a collection tank for collecting the liquid transported by the diversion channel system; the main channel body is embedded in the bottom of the cofferdam frame, one end of the branch pipe is connected to the main channel body, and the other end extends to the bottom of the honeycomb-shaped liquid absorption module; the collection tank is connected to the end of the main channel body.

[0010] By adopting the above technical solution, the main tank, branch pipes, and collection tank of the diversion channel system work together to form a complete liquid transportation and collection path. The main tank is embedded in the bottom of the frame, and the branch pipes extend to the bottom of the liquid suction module, which can fully receive the liquid discharged by the liquid suction module and then transport it to the collection tank through the main tank, realizing the directional recovery of leaked liquid, avoiding the accumulation of liquid in the dike, reducing the difficulty of subsequent treatment, and at the same time, the collection tank facilitates the centralized disposal of the recovered liquid, improving environmental protection.

[0011] Preferably, the main tank has a trapezoidal cross-section and a slope along the liquid flow direction.

[0012] By adopting the above technical solution, the main tank body is designed with a trapezoidal cross section, which can prevent liquid from remaining in the tank and improve the integrity of liquid transportation. The slope set along the liquid flow direction accelerates the liquid flow with the help of gravity, avoids liquid stagnation in the tank, ensures directional transportation efficiency, further optimizes the flow guiding effect, and ensures that leaked liquid is quickly collected in the collection tank.

[0013] Preferably, a capillary guide gap is reserved between the main tank and the honeycomb liquid absorption module.

[0014] By adopting the above technical solution, the capillary guide gap reserved between the main tank and the honeycomb liquid absorption module can guide the liquid adsorbed by the liquid absorption module to flow smoothly into the branch pipe below, avoiding the accumulation of liquid between the module and the tank, ensuring that the liquid enters the guide channel system efficiently, ensuring the continuity of the "adsorption-guide" process, and improving the overall leakage treatment efficiency.

[0015] Preferably, the main channel and branch pipes of the flow guiding channel system are made of acid and alkali resistant materials, and have smooth, burr-free surfaces.

[0017] Preferably, the honeycomb-shaped liquid absorption module is equipped with a visual saturation indicator structure, which can display different colors as the amount of liquid absorbed by the absorption module changes, to prompt the operator to replace the module.

[0018] By adopting the above technical solution, the honeycomb liquid absorption module is equipped with a visual saturation indicator structure that can display different colors as the amount of adsorption changes. Operators can intuitively judge whether the module is saturated without the need for complex detection equipment, and replace the module in time to avoid adsorption failure due to the module saturation not being detected. This ensures the continuous and stable leakage protection capability of the cofferdam, while reducing the difficulty of operation and maintenance costs.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. This type of workshop hazardous chemical leakage containment dike, by incorporating a honeycomb-shaped liquid absorption module, solves the problems of traditional dikes' inability to actively absorb liquid and the low absorption efficiency and easy secondary pollution of improved dikes. The honeycomb-shaped liquid absorption module is composed of a corrosion-resistant hexagonal aluminum honeycomb core material and a surface-modified non-woven fabric containing functional groups specifically for absorbing hazardous chemicals. The surface-modified non-woven fabric is attached to the outer surface of the honeycomb core material and the inner wall of the honeycomb holes. When leaked liquid hazardous chemicals come into contact with the module, the surface-modified non-woven fabric can actively absorb the hazardous chemicals, while the honeycomb core material provides stable structural support for absorption. At the same time, the sides of the module are sealed with snap-fit ​​connectors to prevent liquid leakage from the gaps between the joints. This structure not only overcomes the limitations of traditional dikes that only provide physical barriers and rely on manual cleaning, reducing the risk of liquid diffusion, but also overcomes the defects of improved dikes, such as low absorption efficiency and easy secondary pollution, achieving efficient and environmentally friendly absorption of leaked hazardous chemicals.

[0020] 2. By setting up a diversion channel system, the problems of existing cofferdams lacking a directional flow guidance mechanism and easy liquid accumulation are solved. The diversion channel system includes a main channel, branch pipes, and a collection tank. The main channel is embedded in the bottom of the cofferdam frame. One end of the branch pipe connects to the main channel, and the other end extends to the bottom of the honeycomb liquid absorption module. A capillary flow gap is reserved between the main channel and the honeycomb liquid absorption module. After the liquid absorbed by the honeycomb liquid absorption module reaches a certain amount, it flows through the capillary flow gap to the branch pipe below, and then is collected in the main channel. The main channel has a trapezoidal cross-section and a slope along the liquid flow direction, which guides the liquid to flow towards the end. Finally, the liquid flows into the collection tank connected to the end of the main channel. This directional flow guidance process avoids the accumulation of leaked liquid in the cofferdam, ensures the continuous and efficient absorption of the honeycomb liquid absorption module, reduces the difficulty of subsequent treatment, and realizes the orderly recovery of leaked hazardous chemicals.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0024] Example 1: A containment dike for hazardous chemical leaks in a workshop, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a cofferdam frame 1, with honeycomb-shaped liquid absorption modules 2 arranged in an array on the inner side of the cofferdam frame 1 to absorb leaked liquid hazardous chemicals; a flow channel system 3 is provided at the bottom of the cofferdam frame 1 to receive the liquid discharged from the honeycomb-shaped liquid absorption modules 2 and to achieve directional transportation; the cofferdam frame 1 provides installation support for the honeycomb-shaped liquid absorption modules 2 and the flow channel system 3, and the bottom of the cofferdam frame 1 is provided with a connection structure 4 for fixing it to the workshop floor; the honeycomb-shaped liquid absorption modules 2 are composed of honeycomb core material 201 and surface-modified non-woven fabric 202, and the sides of the honeycomb-shaped liquid absorption modules 2 are provided with buckles for sealing and splicing multiple honeycomb-shaped liquid absorption modules 2. The connector 203, by arranging honeycomb-shaped liquid-absorbing modules 2 in an array inside the cofferdam frame 1, utilizes the composite structure of its honeycomb core material 201 and surface-modified non-woven fabric 202 to actively adsorb leaked liquid hazardous chemicals, overcoming the limitations of traditional cofferdams that only provide physical barriers and rely on manual cleaning, thus reducing the risk of liquid diffusion. The snap-fit ​​connector 203's sealed splicing design prevents liquid from leaking from the gaps between modules, improving the protective sealing performance. The diversion channel system 3 can directionally transport the adsorbed liquid, solving the problem of easy liquid accumulation in existing cofferdams. The connection structure 4 ensures the stable fixation of the cofferdam. The overall structure achieves "adsorption-diversion-fixation" integration, effectively ensuring the protection effect against hazardous chemical leaks in the workshop.

[0025] Reference Figure 1 , Figure 2 and Figure 3The cofferdam frame 1 is welded from stainless steel. Its bottom connection structure 4 is an expansion bolt 401, which penetrates the bottom of the cofferdam frame 1 and connects to the workshop ground for fixation. The honeycomb core material 201 is a regular hexagonal aluminum honeycomb core material 201, and its surface is treated with anti-corrosion coating. A surface-modified non-woven fabric 202 is attached to the outer surface of the honeycomb core material 201 and the inner wall of the honeycomb cells. The surface-modified non-woven fabric 202 contains functional groups for targeted adsorption of hazardous chemicals. The cofferdam frame 1, made of stainless steel, possesses good strength and corrosion resistance, providing stable support in the complex environment of a chemical workshop for a long time, extending the overall service life of the cofferdam. The connection structure 4 is an expansion bolt 401. Expansion bolts 401 securely penetrate the bottom of the frame and connect it to the workshop floor, preventing the dike from shifting during use and ensuring structural stability during leak protection, further enhancing equipment safety. The honeycomb core material 201 is made of regular hexagonal aluminum honeycomb core material 201 and is treated with anti-corrosion coating, ensuring lightweight structure while improving corrosion resistance, making it suitable for hazardous chemical contact scenarios. Surface-modified non-woven fabric 202 is attached to the outer surface of the core material and the inner wall of the honeycomb holes, increasing the contact area with leaked liquids. Its targeted adsorption functional groups for hazardous chemicals improve adsorption efficiency and targeting, avoiding the problem of low efficiency of particulate adsorption materials in improved dikes, and preventing the release of loose materials, thus eliminating secondary pollution.

[0026] Reference Figure 1 , Figure 2 and Figure 4 The diversion channel system 3 includes a main channel 301, branch pipes 302, and a collection tank 303 for collecting the liquid transported by the diversion channel system 3. The main channel 301 is embedded in the bottom of the cofferdam frame 1. One end of the branch pipe 302 is connected to the main channel 301, and the other end extends to the bottom of the honeycomb-shaped liquid absorption module 2. The collection tank 303 is connected to the end of the main channel 301. The main channel 301 has a trapezoidal cross-section and a slope along the liquid flow direction. The main channel 301, branch pipes 302, and collection tank 303 of the diversion channel system 3 cooperate to form a complete liquid transport and collection path. The main channel 301 is embedded in the bottom of the frame, and the branch pipes 302 are connected to the bottom of the cofferdam frame 1. Pipe 302 extends below the liquid suction module 2, fully receiving the liquid discharged from the liquid suction module 2. It is then transported to the collection tank 303 through the main tank 301, realizing the directional recovery of leaked liquid, preventing liquid from accumulating in the containment dam, reducing the difficulty of subsequent treatment. At the same time, the collection tank 303 facilitates centralized disposal of the recovered liquid, improving environmental protection. The cross-section of the main tank 301 is trapezoidal, which can prevent liquid from remaining in the tank and improve the integrity of liquid transportation. The slope set along the liquid flow direction accelerates the liquid flow with the help of gravity, preventing liquid from stagnating in the tank, ensuring directional transportation efficiency, further optimizing the guiding effect, and ensuring that the leaked liquid is quickly collected in the collection tank 303.

[0027] Reference Figure 1, Figure 4 and Figure 5 A capillary guide gap 304 is reserved between the main tank 301 and the honeycomb liquid absorption module 2. The main tank 301 and the branch pipe 302 of the guide channel system 3 are both made of acid and alkali resistant materials with smooth and burr-free surfaces. The honeycomb liquid absorption module 2 is equipped with a visual saturation indicator structure 204, which changes color according to the amount of liquid absorbed by the absorption module 2 to remind the operator to replace the module. The capillary guide gap 304 reserved between the main tank 301 and the honeycomb liquid absorption module 2 can guide the liquid absorbed by the absorption module 2 to flow smoothly into the branch pipe 302 below, avoiding liquid accumulation between the module and the tank, ensuring efficient entry of liquid into the guide channel system 3, ensuring the continuity of the "adsorption-guide" process, and improving the overall leakage. To improve leakage handling efficiency, the main tank 301 and branch pipes 302 of the diversion channel system 3 are made of acid and alkali resistant materials, which can withstand the corrosion of leaked hazardous chemicals, extend the service life of the diversion channel, and prevent liquid leakage caused by corrosion damage to the tank. The smooth and burr-free surface design reduces liquid flow resistance, prevents liquid residue from adhering to the tank wall, ensures smooth diversion, and improves liquid transportation and collection efficiency. The honeycomb liquid absorption module 2 is equipped with a visual saturation indicator structure 204, which can display different colors according to the amount of adsorption. Operators can intuitively judge whether the module is saturated without the need for complicated detection equipment, and replace the module in time to avoid adsorption failure due to undetected module saturation. This ensures the continuous and stable leakage protection capability of the dike, while reducing the difficulty of operation and maintenance costs.

[0028] In this embodiment, by setting up a honeycomb-shaped liquid absorption module 2, the problems of traditional cofferdams being unable to actively absorb liquid and improved cofferdams having low absorption efficiency and being prone to secondary pollution are solved. The honeycomb-shaped liquid absorption module 2 is composed of a corrosion-resistant hexagonal aluminum honeycomb core material 201 and a surface-modified nonwoven fabric 202 containing functional groups specifically for absorbing hazardous chemicals. The surface-modified nonwoven fabric 202 is attached to the outer surface of the honeycomb core material 201 and the inner wall of the honeycomb holes. When leaked liquid hazardous chemicals come into contact with the module, the surface-modified nonwoven fabric 202 can actively absorb the hazardous chemicals, while the honeycomb core material 201 provides stable structural support for the absorption. At the same time, the sides of the module are sealed and spliced ​​through snap-fit ​​connectors 203 to prevent liquid from leaking from the splicing gaps. This structure not only gets rid of the limitations of traditional cofferdams that only provide physical barriers and rely on manual cleaning, reducing the risk of liquid diffusion, but also overcomes the defects of improved cofferdams, such as low absorption efficiency and easy secondary pollution, achieving efficient and environmentally friendly absorption of leaked hazardous chemicals.

[0029] The implementation principle of this application embodiment is as follows: First, the expansion bolts 401 at the bottom of the cofferdam frame 1 are used to connect and fix the bottom of the cofferdam frame 1 to the workshop ground, so that the entire cofferdam is stably installed in the hazardous chemical storage or use area; the cofferdam frame 1 is made of stainless steel and welded to provide stable support for the subsequently assembled honeycomb liquid absorption module 2 and diversion channel system 3. At the same time, the honeycomb liquid absorption module 2 is sealed and spliced ​​by the snap-fit ​​connectors 203 on the side and arranged in an array inside the cofferdam frame 1 to form a protective barrier around the target area, blocking the initial outward spread of leaked hazardous chemicals. The process involves the following: When a liquid hazardous chemical leaks and comes into contact with the honeycomb-shaped liquid absorption module 2, the surface-modified nonwoven fabric 202, attached to the outer surface of the hexagonal aluminum honeycomb core material 201 and the inner wall of the honeycomb holes, actively adsorbs the leaked hazardous chemical using its targeted adsorption functional groups. The corrosion-resistant honeycomb core material 201 provides stable structural support for the surface-modified nonwoven fabric 202, preventing the module from deforming due to liquid adsorption. Simultaneously, the sealed module structure prevents liquid leakage from the gaps, ensuring that the leaked hazardous chemical is efficiently trapped inside the module, avoiding the risk of diffusion. As the honeycomb-shaped liquid absorption module 2 gradually absorbs more liquid, the liquid slowly permeates through the capillary guide gap 304 between the main tank 301 and the honeycomb-shaped liquid absorption module 2, into the branch pipe 302 extending below the module. The branch pipe 302 transports the collected liquid to the main tank 301, which is connected to it. Because the main tank 301 has a trapezoidal cross-section and a slope along the liquid flow direction, the liquid flows towards the end of the main tank 301 under the action of gravity, and finally flows into the collection tank 303 connected to the end of the main tank 301, thus completing the directional guidance and centralized recovery of the leaked hazardous chemicals. In the flow diversion system 3, the main tank 301 and the branch pipes 302 are made of acid and alkali resistant materials with smooth, burr-free surfaces, which not only prevents corrosion and damage from hazardous chemicals but also reduces liquid flow resistance and ensures smooth flow. During the adsorption and diversion process, the visual saturation indicator structure 204 on the honeycomb liquid absorption module 2 changes color with the amount of adsorption by the module. When the color change reaches the preset saturation indication state, the operator can intuitively judge that the module is saturated and replace it with a new honeycomb liquid absorption module 2 in time, ensuring that the dike has a continuous ability to adsorb and protect against leaked hazardous chemicals and ensuring the safety of workshop production.
