JJH-1200TW iodine adsorption purification car

The JJH-1200TW iodine adsorption purification vehicle is commonly used in nuclear facility decommissioning and dismantling, radioactive decontamination, nuclear equipment maintenance, waste sorting, and other sites to ensure environmental cleanliness and prevent internal radiation hazards; Used to remove gaseous radioactive aerosols and radioactive iodine from the air in the nuclear air isolation room (SAS), achieving the purpose of purifying the air and ensuring the safety of operators.

Equipment characteristics and progressiveness

This car adopts a newly designed top tightening device, which is more convenient for fixing and completely sealing the filtering device.

The high-efficiency filter used in this car adopts the current domestic new technology polymer material filter material, which is conducive to enhancing the filtration effect on nuclear air.

This car adopts a high-quality steel shell (spray painted), which is beneficial for extending the service life, reducing maintenance costs, and easy to clean and remove dirt.

This car has undergone structural optimization design to reduce the overall weight, facilitate movement and transportation, and replace high-efficiency filtersIodine adsorber.

This small car has added a storage cabinet at the bottom of the car, which can store air ducts, cables, tools, etc. with the car, making the appearance beautiful and tidy.

The sealed box part of this car adopts frame reinforced support components inside the box, making the structure of the sealed box more solid and reliable.

Instructions for use

(1) Equipment assembly

Installation of iodine adsorber. During installation, the airflow direction of the car should be consistent with the direction indicated on the high-efficiency filter and iodine adsorber. The sealing gasket should be evenly compressed, and the compression amount should not be too large, preferably controlled at 40% -60%. If the sealing gasket is found to be damaged or lose elasticity, it should be replaced.

Installation of air ducts. When installing the air duct, a stainless steel hose clamp should be used to tightly connect the air duct to the air inlet of the trolley to ensure good sealing.

Installation of sealed doors. When installing the sealed door, use a fixed handwheel to tighten the seal.

(2) Use

In order to ensure the safe operation of JJH1200 iodine adsorption trolley, regular on-site inspection tests should be conducted after the trolley has been in use for a period of time.

The relative humidity of the airflow should be less than 50%, otherwise a drying device should be installed.

To ensure the normal use of the car, the pressure difference of the iodine adsorber should be monitored on a daily basis. If the display of the differential pressure gauge exceeds twice the initial resistance, it needs to be replaced, or if the radiation dose rate exceeds 250uSv/h, the iodine adsorber needs to be replaced.

(3) Disassemble the high-efficiency filter and iodine adsorber

Put on latex gloves, loosen the top tightening device, and remove the iodine adsorber from the rack.

Seal the extracted iodine adsorber with a plastic bag.
