[0068] The material inside Filter Box 2 is: activated carbon

[0069] Characteristics

[0070] Activated carbon has a highly developed pore structure and a large specific surface area, capable of adsorbing a variety of organic and inorganic substances. It has good adsorption capacity for many hazardous chemicals such as volatile organic compounds (VOCs) and toxic gases.

[0071] Different types of activated carbon, such as granular activated carbon, powdered activated carbon, and activated carbon fibers, can be selected according to the nature of the leaked hazardous chemicals and the filtration requirements.

[0072] Filtration Process

[0073] During the first filtration, activated carbon can adsorb a large number of hazardous chemical molecules. As the filtration progresses, when the activated carbon approaches saturation, it can be regenerated by methods such as heating, steam purging, or chemical regeneration to restore its adsorption capacity for re-filtration.

[0074] II. Zeolite

[0075] Characteristics

[0076] Zeolite is a mineral with a microporous structure, having good adsorption performance and ion exchange capacity. It can adsorb some molecules of specific sizes, such as certain organic compounds and heavy metal ions.

[0077] Zeolite also has a certain adsorption effect on moisture and some polar molecules, and can play a role in drying and removing impurities during the filtration process.

[0078] Filtration process

[0079] In the initial stage of hazardous chemical leakage, zeolite can quickly adsorb some hazardous chemicals. After being used for a period of time, it can be regenerated by high-temperature treatment or chemical methods and then used for filtration again to achieve multiple uses.

[0080] III. Polymer adsorption resin

[0081] Characteristics

[0082] Polymer adsorption resin is an artificially synthesized material with specific functional groups, which can selectively adsorb specific hazardous chemicals. For example, resins with functional groups such as amino groups and carboxyl groups can adsorb heavy metal ions; resins with specific aromatic ring structures can adsorb organic dyes, etc.

[0083] The adsorption capacity of polymer adsorption resin is relatively large, and the types and amounts of functional groups can be adjusted to meet the filtration requirements of different hazardous chemicals.

[0084] Filtration process

[0085] When used for the first time, polymer adsorption resin can efficiently adsorb the target hazardous chemicals. When the adsorption is saturated, an appropriate solvent can be used for elution regeneration, and then it can be put into use again for multiple filtrations.

[0086] IV. Fiber filter media

[0087] Characteristics

[0088] Fiber filter media such as glass fiber and polyester fiber have high filtration accuracy and large filtration area. Solid particles and droplets in hazardous chemical leakage can be removed by physical interception.

[0089] Some special fiber filter media can also be surface-treated to increase the adsorption performance for specific hazardous chemicals.

[0090] Filtration process

[0091] During the initial filtration, fiber filter media can remove larger particle impurities and some hazardous chemicals. After being cleaned and treated, it can be used for filtration again to achieve the purpose of multiple filtrations. However, the adsorption capacity of fiber filter media is relatively small, and it may need to be used in combination with other materials.

[0092] V. Composite Filter Material

[0093] Characteristics

[0094] A composite filter material composed of multiple different materials can give full play to the advantages of various materials, improving the filtering effect and service life. For example, combining activated carbon with zeolite, fiber filter media, etc. can achieve multiple filtering functions such as adsorption, ion exchange, and physical interception simultaneously.

[0095] The composite filter material can be customized according to different hazardous chemical leaks to meet specific filtering requirements.

[0096] Filtering Process

[0097] In the treatment of hazardous chemical leaks, the composite filter material can be filtered multiple times. After each filtration, corresponding regeneration treatment or replacement of some components can be carried out according to the characteristics of the material to ensure the stability and reliability of the filtering effect.

[0098] The working principle of a rapid detection device for hazardous chemical leaks on a bridge deck provided by the present utility model is as follows:

[0099] During use, when disassembling and replacing the filter box 2 inside the mounting frame 1, first separate the first connector 51 and the first connection sleeve 52. After the first connector 51 and the first connection sleeve 52 are separated, then separate the second connection sleeve 81 and the second connector 82, and then pull the filter box 2 to move outward from the mounting frame 1. When the filter box 2 moves outward from the mounting frame 1, it drives the disassembly block 32 at the bottom to separate from the disassembly groove 31 opened on the mounting frame 1.
