Description

Technical Field

[0001] This utility model relates to the field of modular cabin technology, and in particular to a nuclear emergency decontamination modular cabin. Background Technology

[0002] A nuclear emergency decontamination container is a type of equipment used for emergency response to nuclear and chemical accidents. It is typically converted from a shipping container and features fewer loading and unloading steps, high efficiency, and convenient transshipment.

[0003] Chinese patent CN221951838U discloses a nuclear emergency decontamination cabin, including a main cabin body and a decontamination area. The main cabin body has a contaminated area, a clean area to the left of the contaminated area, and the decontamination area located behind the clean area. A generator area is located to the right of the decontamination area. The inner wall of the decontamination area is equipped with baffles. This invention uses baffles evenly distributed within the decontamination area to evenly isolate it into five working decontamination areas for simultaneous use. This allows for multiple decontamination tasks to be performed simultaneously, improving decontamination efficiency, reducing interference between different decontamination tasks, and improving decontamination quality. Disinfectant liquid is input through conduits and sprayed onto nozzles for decontamination. The bottom support plate has a mesh structure, and wastewater is sent into a collection tank and pumped out through a water pipe for centralized treatment.

[0004] The aforementioned patents lack radiation isolation capabilities, causing radiation from radioactive materials cleaned from the decontamination chamber to diffuse outwards. Furthermore, the lack of an effective ventilation system results in poor airflow within the chamber during high temperatures, leading to a stuffy environment and negatively impacting the operator's experience. Therefore, there is an urgent need to develop a nuclear emergency decontamination chamber with excellent radiation isolation and ventilation performance, providing greater comfort during use, to overcome the current shortcomings and meet current requirements. Utility Model Content

[0005] The purpose of this invention is to provide a nuclear emergency decontamination cabin to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A nuclear emergency decontamination cabin includes a cabin body, an entry door, a ventilation mechanism, a first radiation shielding layer, an exhaust mechanism, a second radiation shielding layer, an exit door, and a transparent observation window. The entry door and the exit door are rotatably connected to the cabin body via hinges. The entry door opens outward, and the exit door opens inward. A transparent observation window is installed on the cabin body, and a transparent ionizing radiation shielding film is provided on the transparent observation window. The first radiation shielding layer is fixed to the inner side of the cabin body, and the second radiation shielding layer is fixed to the entry door. A ventilation mechanism inserted into the left side of the cabin body is installed, and an exhaust mechanism is installed at the right end of the cabin body. The exhaust mechanism includes an exhaust pipe, a storage mesh box, a handle, a plug, and zeolite particles. The exhaust pipe is fixed to the cabin body, and two storage mesh boxes are detachably installed inside the exhaust pipe. The storage mesh boxes are filled with zeolite particles, and a handle is fixed to the top of the storage mesh box. A plug is detachably installed at the upper end of the storage mesh box.

[0008] Preferably, the plug is fixed to the storage mesh box by threads.

[0009] Preferably, both the first radiation isolation layer and the second radiation isolation layer are made of lead plates.

[0010] Preferably, the ventilation mechanism includes: a mounting cylinder, a dust filter, and a fan. The mounting cylinder is fixed to the cabin body, the fan is installed inside the mounting cylinder, and the dust filter is fixed to the left side of the mounting cylinder.

[0011] Preferably, the cabin is equipped with storage cabinets.

[0012] Preferably, the cabin is equipped with a washing pool, trash cans, and a shower area.

[0013] The beneficial effects of this invention are as follows: When using this nuclear emergency decontamination cabin, personnel enter the cabin for emergency decontamination. They can absorb radiation in the cleaning pool or shower in the shower area to wash away contaminated areas. Wastewater is discharged through a drainpipe to a dedicated external radiation wastewater treatment facility. After closing the entrance door, radiation is isolated by the first and second radiation isolation layers to reduce outward radiation propagation. Simultaneously, fans blow air into the cabin, filtering dust from the airflow through a dust filter. The airflow inside the cabin is discharged through an exhaust stack, a storage mesh box, and zeolite particles to maintain air circulation. Furthermore, the zeolite particles adsorb radioactive particles mixed in the discharged airflow, reducing radiation leakage. In summary, this invention has excellent radiation isolation and ventilation performance, making it more comfortable to use. Attached Figure Description
