Description

Technical Field

[0001] This utility model relates to the field of occupational health engineering protective equipment technology, specifically to a simulation experimental chamber. Background Technology

[0002] With industrial development, chemical enterprises frequently use or generate highly toxic, corrosive, and toxic materials during production. Because production processes cannot be completely sealed off, exceeding the standards for toxic substance concentrations at work sites is a frequent occurrence, easily leading to occupational diseases among workers. Occupational hazard engineering protection, as a "primary prevention" measure for occupational disease control, can fundamentally control and eliminate occupational hazards in the workplace. However, the development of occupational hazard engineering protection technology is currently slow, and related experimental research equipment is insufficient. Existing occupational health technical service institutions mainly focus on testing and evaluation, with few institutions engaged in research and treatment of occupational hazard engineering protection. Furthermore, existing experimental equipment suffers from problems such as unreasonable structure, inability to simulate real chemical leak scenarios, and weak integration between protective facilities and monitoring systems, making it difficult to meet the needs of research on chemical toxic hazard engineering protection technology and providing accurate data support for optimizing protective facilities. Therefore, there is an urgent need for an experimental chamber with a reasonable structure that can effectively simulate chemical leak scenarios and integrate protection and monitoring functions to promote the research and development of chemical toxic hazard engineering protection technology. Utility Model Content

To achieve the above objectives, this utility model adopts the following technical solution: A simulated experimental chamber includes a main body of the experimental chamber and an online monitoring data analysis room adjacent to the main body of the experimental chamber; the main body of the experimental chamber has a door on one side and a window on the other side, and inside, from north to south, are arranged a movable online chemical toxicant detection device, a gas cylinder cabinet, a water bath, an activated carbon adsorption tower, a spray tower, and a variable frequency fan; a universal suction hood is provided above the water bath, the universal suction hood is connected to the activated carbon adsorption tower through a pipe, the activated carbon adsorption tower is connected to the spray tower through a pipe, the spray tower is connected to the variable frequency fan through a pipe, and the variable frequency fan has an exhaust port to the atmosphere; the main body of the experimental chamber is constructed with PP wall panels to form a fully enclosed environment, and an acid and alkali resistant explosion-proof viewing glass window is provided between the main body of the experimental chamber and the online monitoring data analysis room, and the control cabinet of the variable frequency fan is located in the online monitoring data analysis room. Furthermore, the portable online chemical toxicant detection device includes portable online chemical toxicant detection device A and portable online chemical toxicant detection device B, whose positions can be flexibly adjusted according to experimental needs to simulate toxicant leaks at different locations. Furthermore, the equipment layout within the main body of the experimental chamber adopts a "static-dynamic separation" principle. Static equipment includes gas cylinder cabinets and gas detection alarms, while dynamic equipment includes variable frequency fans, spray towers, activated carbon adsorption towers, water baths, universal suction hoods and pipes, and fan variable frequency control boxes. This layout helps improve the stability and safety of the experiment. Furthermore, the online monitoring data analysis room is equipped with detection modules, an online monitoring platform, and a computer. The detection modules include dust (total dust) detection modules, dust (respirable dust) detection modules, carbon monoxide detection modules, sulfur dioxide detection modules, ammonia detection modules, chlorine detection modules, methane detection modules, methanol detection modules, and noise detection modules, enabling real-time monitoring of multiple occupational hazard factors. Furthermore, the spray tower uses a corrosion-resistant PP material for its body, and its interior is equipped with spiral nozzles and a multi-faceted hollow spherical packing layer. The spiral nozzles achieve atomization, and the multi-faceted hollow spherical packing layer increases the gas-liquid contact area, improving the efficiency of toxic substance treatment. Furthermore, the activated carbon adsorption tower uses a double-layer honeycomb activated carbon box, with an iodine value ≥1000mg / g, ensuring excellent adsorption performance for chemical toxins. Furthermore, the universal suction hood has a coverage radius of 1.5m and a collection efficiency ≥95%, effectively collecting toxic gases generated by equipment such as water baths. Furthermore, the gas cylinder cabinet is equipped with a toxic gas detection alarm system, which can monitor the concentration of toxic substances within the cabinet in real time and promptly issue alarm signals to ensure experimental safety.

Inside the main body 1, from north to south, are a portable online chemical toxicant detection device A2, a portable online chemical toxicant detection device B3, a gas cylinder cabinet 4, a water bath 5, an activated carbon adsorption tower 6, a spray tower 7, and a variable frequency fan 9. The portable online chemical toxicant detection devices A2 and B3 can be moved to different locations to simulate chemical toxicant leaks at different points according to experimental needs. The gas cylinder cabinet 4 stores the gases required for the experiment and is equipped with a toxic gas detection alarm system for real-time monitoring and alarm. The water bath 5 is equipped with a universal suction hood with a coverage radius of 1.5m and a collection efficiency of ≥95%, effectively collecting the toxic gases generated during heating in the water bath 5. The universal suction hood is connected to the activated carbon adsorption tower 6 via a pipe. The activated carbon adsorption tower 6 uses a double-layer honeycomb activated carbon box with an iodine value ≥1000mg / g, which performs preliminary adsorption treatment on toxic gases. The activated carbon adsorption tower 6 is connected to the spray tower 7 via a pipe. The spray tower 7 uses a corrosion-resistant PP material tower body and has a spiral nozzle and a multi-faceted hollow sphere packing layer inside. The spiral nozzle achieves atomization, and the multi-faceted hollow sphere increases the gas-liquid contact area for further treatment of toxic gases. The spray tower 7 is connected to the variable frequency fan 9 via a pipe. The variable frequency fan 9 has an exhaust port 10 to the atmosphere to discharge the treated gas. The main body of the experimental chamber 1 is constructed with PP wall panels to create a fully enclosed environment with acid and alkali resistance meeting ASTM D543 standards, ensuring that chemical leaks during the experiment will not spread to the external environment.
