The large space three-dimensional warehouse is composed of high-level shelves, stackers, conveyors and other peripheral equipment, automatic control devices, information transmission devices and computers. It is a warehouse that integrates modern building skills with the storage of expensive goods. In the event of a fire, its losses are huge. Therefore, the fire protection of this site is particularly important.

The traditional automatic water spraying device is not practical for automatic fire extinguishing devices in military warehouses such as clothing. And the fire extinguishing effect is not a dream. The penetration force of a fire-extinguishing water point through the flame to the surface of the incinerated substance depends on the momentum of the water point. When the height of the space is greatly affected by air buoyancy, the drop speed of the water points of the automatic sprinkler is slowed down, and the water points are distributed, so that it is difficult for the water to pass through the flame roll feathers to the surface of the incinerator. Because the spray area is relatively large, the current is distributed, and the ignition point cannot be targeted, so the fire cannot be controlled in a short period of time. Water resources have not been usefully scammed. Unique is that there are many kinds of items in the warehouse. Many materials are damaged when they encounter water, forming a secondary loss.

Over the years, the hanging type ultra-fine dry powder fire extinguishing device has been used in various types of warehouse fire fighting, and has been approved by users and fire supervisors. Superfine dry powder fire extinguishing agent is a highly effective fire extinguishing agent for fire extinguishing efficiency. It does not destroy the atmospheric ozone layer, and its temperature effect potential is zero. No irritation to the human body, no erosion to the protection. Residues are easy to sort out after fire fighting. Ultrafine dry powder fire extinguishing agent organically combines the advantages of chemical fire extinguishing and physical fire extinguishing. It has a strong pressure on the burning chain of flame, and has a suffocating effect on the surface burning. The fire extinguishing power of ultrafine dry powder is 8-10 times that of ordinary dry powder.

The use of a hanging ultra-fine dry powder automatic fire extinguishing device in a three-dimensional warehouse has the following advantages. The first is the pipeless network design, which is highly targeted for independent installation. In addition, it has the characteristics of reliable start-up, atmospheric pressure reserve, economic cost, efficient fire extinguishing, ecological environment protection, long service life, and care-free. It may be installed in layers according to several storage units on the shelf, which unit's goods catch fire during operation, and which unit's fire extinguishing device is activated by a linkage component (built-in 68 ° C temperature sensing element) to practice fire extinguishing. Unlike a pipe network fire extinguishing device, the entire fire extinguishing agent will be sprayed as soon as it is started. In view of the unattended characteristics of the main warehouse, the thermal conduction method is adopted to start the equipment, and no accidental operation of the equipment will occur without a fire.

Another feature of the hanging ultra-fine dry powder automatic fire extinguishing device is that it may be possible to complete the one-sided destruction of the protected object in an open space. This feature is quite practical for handling fire-fighting devices in three-dimensional warehouses. As long as the volume of the protected object can be calculated, the amount of extinguishing agent can be calculated. In addition, products of different models can be selected according to the height of the shelves.

In summary, the hanging type ultra-fine dry powder automatic fire extinguishing device will have excellent prospects for fire protection in a three-dimensional warehouse that handles large spaces.
