After knowing its specific storage requirements, ZOYET conducts on-site surveys, carries out project discussions, and the technicians issue storage plans - designing the size (length * width * height) and quantity of the storage box equipment from the storage demand area. Identification of storage box layout (in line with relevant national standards), electrical interface location, equipment basic size (length * width * height), storage box power control container, storage box internal fire partition wall and material storage layout, According to the MSDS of the chemicals to be stored and the storage conditions of mutual forbidden Settings, the system is designed and equipped with temperature control, exhaust air, gas detection, explosion prevention, leakage prevention, lightning protection, anti-static, monitoring, sound and light alarm and fire protection.
The final scheme was approved, put into production, delivered recently, and is now in use.
Combined with the above factors, this project designed two containers to meet the storage needs:
Outer dimension of main body 1: length 6000* width 3000* height 3000mm
Body 2 external dimensions: length 9000* width 3000* height 3000mm
The container adopts walk-in storage, and the side door is equipped with a ramp to facilitate personnel to carry goods in and out.
The circuit in the container is set in strict accordance with the explosion-proof requirements, and all the configurations in the container are equipped with qualified explosion-proof lamps and explosion-proof electrical equipment.
Safety warning signs are posted in a prominent position, and the safety signs comply with the GHS "Global Harmonized System of Classification and Labeling of Chemicals" (the signs are made of corrosion-resistant materials).
System introduction：
Explosion-proof temperature control system
The inner wall of the container should be equipped with 100mm thick class A fire insulation to prevent the internal temperature from overheating when the sun is shining or anti-freezing in winter;
The container body is equipped with explosion-proof refrigeration equipment, which can effectively control the internal temperature of the cabinet when the room temperature is too high and too low, and meet the temperature requirements of GB17914-2013 "Technical Conditions for storage and maintenance of Flammable and Explosive Commodities". When the temperature in the container is close to the set temperature value, the explosion-proof air conditioner will automatically turn on. When the temperature exceeds the set temperature value, the system will automatically start the audible and visual alarm light, and the user can choose to manually turn on the cooling system.
Lightning protection and anti-static system
The explosion-proof electrical cabinet is equipped with a lightning surge protection device, and the user buries flat iron so that the cabinet can be placed in place and connected.
Using anti-static surface layer, three separate coating, so that the resistance value of the container is lower than the conventional standard. A ring of anti-static copper strips is installed in the container. Static electricity is led into the ground through the wire to release static electricity and avoid fire caused by electrostatic sparks.
The explosion-proof electrostatic release column is set at the door of the container, and the staff should touch it to remove the static electricity of the human body before entering.
Anti-leakage
The ground area in the container is provided with an anti-leakage layer, the height is about 15cm, the bottom of the container adopts a thick anti-slip printing pedal, the top is laid with galvanized grating, and the cabinet is provided with a discharge outlet at one end. Customers need to collect and treat waste liquid on a regular basis.
Explosion-proof ventilation&purification system
Ventilation blinds are provided in the cabinet, and anti-pest nets are provided inside the blinds. The material of the ventilation device should be non-combustible or flame retardant.
The explosion-proof axial fan is used in the forced exhaust system. The fan only starts when the combustible /VOC gas alarm and the morning and evening air change, and stops the fan operation when the smoke fire alarm is detected. Equipped with activated carbon filter.
Environmental monitoring system
The container is equipped with explosion-proof monitoring, with night vision function, 360° monitoring the situation in the container.
The container is equipped with explosion-proof combustible gas probe, explosion-proof temperature probe, explosion-proof smoke sensor probe, any probe starts the sound and light alarm outside the cabinet. Meet the requirements of GB17914-2013 "Technical Conditions for Storage and Maintenance of Flammable and Explosive Commodities" to install combustible gas detectors. When detecting alarms in the cabinet, the alarm bell and lamp are automatically activated, and the fan is cut off when the smoke alarm is generated.When the gas concentration in the cabinet is close to the safety critical value of 20%-30%, the control system will intelligent implementation of various disposal measures, in the case of possible danger, the control system will start the audible and visual alarm, the alarm sound is above 85 decibels, and the port reserved in the explosion-proof distribution cabinet can provide remote warning to the user's fire system host.
Intelligent management system
The intelligent management software platform should be able to monitor the internal storage temperature, volatile organic matter concentration and combustible gas concentration in real time online through the mobile terminal (ios system, Android system through app or wechat mini program) and the computer terminal, as well as the internal alarm situation. The whole equipment is centrally controlled by the microcomputer system. According to the parameters set by the customer, the computer system automatically detects the sensor parameters in real time, and intelligent linkage controls the start and stop of the exhaust system, the start and stop of the temperature control system, the switch of the lighting system, early warning and alarm.
