Dangerous chemicals must be stored in the cold storage at 2-8℃ to be safe. The design of explosion-proof cold storage is stricter, more precise and more reliable than that of conventional cold storage. Hazardous chemicals should not be stored in the warehouse in the open air or at room temperature. The building structure of cold storage for storing dangerous chemicals is also higher than the standard of ordinary cold storage. Chemical explosion-proof cold storage is mainly used for inflammable and explosive dangerous goods such as chemicals, electronics, flavors and fragrances, alcohol and ethanol. Chemical cold storage is directly used to store and transport dangerous goods in dangerous places with explosive gas.

(1). The first step in the design of chemical cold storage is to consider the site selection requirements of chemical cold storage. The installation location of chemical cold storage should be far away from densely populated areas, and the selected installation ground should be neat to see if it is suitable for new chemical cold storage. The horizontal position of chemical cold storage should be slightly lower than the ground, so that even if an accident occurs, it will not affect the surrounding environment.

(2) Chemical cold storage is usually made of stainless steel, so the refrigeration equipment outside the warehouse must be isolated, and the internal fan must also have explosion-proof function. Adopt automatic temperature control, automatic recording and automatic alarm device. Experts remind: Secondly, the chemical cold storage installation engineering team must know the chemical explosion-proof cold storage like the back of his hand and have a lot of installation experience in this field. All details of chemical devices should be treated with caution. Chemical cold storage has different grades according to the types of stored items. For ordinary chemical cold storage, as long as the internal fan motor is replaced by chemical explosion-proof motor, the electric control box is chemical explosion-proof electric box, the lighting in the warehouse is chemical explosion-proof lamp, and the switch is chemical explosion-proof switch.

(3) Conduct special training for the product management personnel of chemical cold storage. During the training, we must pay special attention to the safety of chemical cold storage, which equipment can be operated and which equipment can not be operated casually, because once the operation is wrong, the cold storage can not be used normally, and even an explosion accident may occur. The management personnel of chemical cold storage must be cautious.

(4) Chemical explosion-proof cold storage needs special maintenance. If the temperature is abnormal due to the failure of the cold storage, the maintenance personnel should immediately notify the refrigerator operator to check and repair after receiving the alarm. If the fault can be solved on site, the maintenance personnel should observe the processed temperature and humidity data until the temperature and humidity are normal. If the fault cannot be eliminated on the spot, the maintenance personnel should apply for immediate shutdown and maintenance of the cold storage, and transfer the chemicals to other cold storage. www.mhb2c.com
