[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] like Figure 1-5 As shown in some illustrative embodiments, a chemical splash cleaning and neutralization treatment device for a chemical production line is provided. By arranging modular treatment modules, it can promptly contain, identify, clean, adsorb, and neutralize chemicals splashed on the production line, thereby solving the problems of slow response, complex operation, and limited effectiveness in the prior art for handling chemical splashes.

[0026] The treatment device of this application consists of several treatment modules, which are connected in sequence to enclose and form a working area. The treatment modules have the same or similar structure, and the number of them can be selected according to needs. For example, four treatment modules can be set up, connected in sequence, and after sealing measures are taken, they will finally form a rectangular fence. The rectangular fence surrounds the specific equipment or operating area where the chemical spill occurs, that is, it encloses and forms a temporary working area. The function of this working area is to delineate the operating boundary for subsequent treatment.

[0027] The processing module includes: a detection unit 100, a multi-stage filtration and adsorption unit 200, a neutralization unit 300, and a rinsing unit 400.

[0028] The detection unit 100 is located on the side of the multi-stage filtration and adsorption unit 200 facing the work area, i.e., the side closest to the splash source. Specifically, the detection unit includes: a pH sensor, a volatile organic compound (VOC) sensor, and an ion-selective electrode. When chemicals splash into the work area, the detection unit collects relevant data: the pH sensor is used to initially determine the acidity or alkalinity of the chemicals; the VOC sensor is used to detect the presence and approximate concentration of volatile organic solvents; the ion-selective electrode can be selected as needed, for example, for common heavy metal ions (such as lead, mercury, and copper ion selective electrodes) or specific anions (such as chloride and fluoride ion selective electrodes) to identify specific types of chemical substances. The detection unit transmits the collected data to the control unit in real time. The control unit determines the approximate type and properties of the chemicals based on the sensor data, providing a basis for subsequent processing procedures.

[0029] The multi-stage filtration and adsorption mechanism 200 includes: a platform 210, a selective adsorption layer, a support 230, a telescopic component 240, a primary filtration layer 220, and a general adsorption layer 250.

[0030] An adsorption chamber 211 is provided in the middle of the enclosure 210, making the enclosure 210 a rectangular frame structure. When not in use, the selective adsorption layer is located above the adsorption chamber 211. The selective adsorption layer consists of multiple sequentially arranged classified adsorption layers 260. Based on the monitoring data of the detection agency 100, one or more classified adsorption layers 260 that are compatible with the splashed chemicals can be selected, moved down, and entered into the adsorption chamber 211 to perform the adsorption operation.

[0031] The enclosure 210 has an inlet 212 on one side facing the work area, with a primary filter layer 220 installed inside the inlet 212. An outlet 213 is located on the other side of the enclosure 210, with a general-purpose adsorption layer 250 installed inside the outlet 213. Both the inlet 212 and outlet 213 are connected to the adsorption chamber 211. The function of the enclosure 210 is to physically contain and guide the flow of splashed liquid. The splashed liquid first flows into the primary filter layer 220 inside the inlet 212, then enters the adsorption chamber 211, is treated by the selective adsorption layer, and finally enters the general-purpose adsorption layer 250 inside the outlet 213.

[0032] The primary filtration layer 220 uses materials with large pore size and high porosity, such as coarse filter screens or fluffy absorbent cotton, to intercept larger solid particles, precipitates, or preliminarily filter out some macromolecular substances. The selective adsorption layer consists of multiple sequentially arranged classifying adsorption layers 260, each targeting a specific type of chemical. For example, one classifying adsorption layer 260 is filled with a strongly acidic cation exchange resin to adsorb alkaline substances; another classifying adsorption layer 260 is filled with activated carbon to adsorb organic solvents; and yet another classifying adsorption layer 260 is filled with a chelating resin containing specific ligands to adsorb heavy metal ions. This multi-stage design allows the selective adsorption layer to selectively prioritize the passage of substances through the corresponding classifying adsorption layer based on the preliminary judgment of the detection agency 100, thereby improving adsorption efficiency.

[0033] A support 230 is installed on the top of the platform 210. Multiple telescopic components 240 connected to the sorting and adsorption layers 260 are mounted on the support 230. Each telescopic component 240 corresponds to one sorting and adsorption layer 260, so that when the telescopic component 240 extends, it pushes the sorting and adsorption layer 260 into the adsorption chamber 211. The telescopic component 240 can be a cylinder, hydraulic cylinder, or electric push rod, etc.

[0034] Under normal conditions, the classified adsorption layer 260 is partially or completely located outside the enclosure 210 for easy replacement. When a chemical spill is detected and a specific classified adsorption layer is required, the control unit can instruct the corresponding telescopic component 240 to extend, pushing the corresponding classified adsorption layer 260 into the adsorption chamber 211, positioning it in the working position between the inlet 212 and the outlet 213. This guides the spilled liquid to flow through this layer first, thereby achieving rapid switching and positioning of the adsorption material.

[0035] Each classifying adsorption layer 260 can be designed as an independent, replaceable modular unit, specifically including a housing 261 filled with adsorbent material. An inlet channel 262 is provided at the bottom front of the housing 261, through which splashed liquid enters the classifying adsorption layer 260. A discharge port 263 is provided at the top of the housing 261, connected to the first inlet 251 of the general adsorption layer 250 via a delivery pipe 264. After being processed by the classifying adsorption layer 260, the splashed liquid enters the general adsorption layer 250 via the discharge port 263 and the delivery pipe 264.

[0036] The general-purpose adsorption layer 250 is filled with a versatile adsorption material, such as activated carbon with a high specific surface area, macroporous adsorption resin, or ultrafine fiber adsorption cotton, capable of adsorbing various types of chemicals. The general-purpose adsorption layer 250 also has a second inlet 252 on the side facing the adsorption chamber 211. This dual-inlet design of the general-purpose adsorption layer 250 increases its flexibility.

[0037] When the testing agency 100 determines that the chemical properties are clear and there is a specific classification adsorption layer 260, it can choose to enter from the first inlet 251, pass through the classification adsorption layer 260 and then enter the general adsorption layer 250.

[0038] When the chemical properties are complex or the detection is unclear, it is also possible to choose to enter directly from the second inlet 252, and after the liquid is mixed, it can directly enter the general adsorption layer 260 for broad-spectrum adsorption.

[0039] After the splashed liquid is treated, when rinsing with the rinsing mechanism 400, the rinsing liquid directly enters the general adsorption layer 260 through the primary filter layer 220.

[0040] The neutralization mechanism 300 is located on the side of the multi-stage filtration and adsorption mechanism 200 away from the working area. The neutralization mechanism 300 includes: a neutralization chamber 410, a pump 420, a supply pump 430, and several neutralizing agent storage tanks 440. The supply pump 430 is installed on the pipeline connecting the neutralizing agent storage tanks 440 and the neutralization chamber 410. The outlet end of the pump 420 is connected to the neutralization chamber 410 through a pipeline. The outlet of the general adsorption layer 250 is connected to the inlet end of the pump 420.

[0041] Neutralization chamber 410 is used to contain liquid flowing out of general adsorption layer 250, which has undergone preliminary adsorption but may still contain residual chemically active substances. Pump 420 pumps the liquid from general adsorption layer 250 to neutralization chamber 410. The device is equipped with several neutralizing agent storage tanks 440, which store neutralizing agents for different acidity and alkalinity, such as acidic tanks storing citric acid solution and alkaline tanks storing sodium bicarbonate solution. Each neutralizing agent storage tank 440 is connected to a supply pump 430. The control unit selects and starts the supply pump 430 of the corresponding neutralizing agent storage tank based on information such as pH value provided by detection mechanism 100, pumping an appropriate amount of neutralizing agent into neutralization chamber 410 to neutralize the residual acid or alkali in the liquid.

[0042] The rinsing mechanism 400 is located on top of the multi-stage filtration and adsorption mechanism 200. The rinsing mechanism 400 includes: a rinsing liquid storage tank 310, a spray pump 320, a spray frame 330, and several spray heads 340. The inlet end of the spray pump 320 is connected to the rinsing liquid storage tank 310, and the outlet end of the spray pump 320 is connected to the spray head 340. The spray head 340 is located on the spray frame 330.

[0043] The flushing fluid storage tank 310 stores cleaning water or a specific flushing fluid. The spray rack 330 can be designed to rotate or be angled to cover most of the work area. When a splash is detected, the control unit can activate the spray 320, which sprays and flushes the work area through the spray heads 340. The flushed liquid containing chemicals flows into the inlet of the enclosure for subsequent processing.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
