A kind of barrier fire extinguishing board for energy storage system

Abstract

The present invention provides a barrier fire extinguishing plate for an energy storage system, the barrier fire extinguishing plate is provided with a number of spray holes for spraying fire extinguishing agent, the barrier fire extinguishing plate is provided with a fire extinguishing agent channel, the spray holes and fire extinguishing The fire extinguishing agent channel is connected, and the two sides of the fire extinguishing agent channel are provided with a barrier plate. The surface of one side of the barrier plate is provided with a number of through holes for the spray holes to extend. The fire extinguishing agent channel is a pipeline type fire extinguishing agent channel or a flow channel. Extinguishing agent channel. The barrier fire extinguishing board of the present invention can not only realize accurate spraying of fire extinguishing agent, realize rapid fire extinguishing at the initial stage of fire, but also ensure effective thermal barrier.

Description

technical field [0001] The invention belongs to the field of fire extinguishing structures, and in particular relates to a barrier fire extinguishing board for an energy storage system. Background technique [0002] As my country pays more and more attention to environmental protection issues and the substantial reduction in the production cost of lithium-ion batteries, the use of lithium-ion batteries as a new energy source instead of traditional energy has become the first step towards a low-carbon economy in my country and is widely used in energy storage field. In recent years, with the rapid development of my country's energy storage industry, it not only plays an important role in the power generation side, transmission and distribution side and load side of the large power grid, and improves power quality, but also plays an important role in the user side. The application of distributed energy in microgrids is also becoming more and more extensive. Grid energy storage ...

Problems solved by technology

For example: (1) Cabinet-type heptafluoropropane gas fire extinguishing device, the space inside the energy storage cabinet is narrow and long, and each battery box in the cabinet communicates with the outside world only through vent holes, so it is difficult for the gas fire extinguishing agent to enter, and it is impossible to effectively achieve full submersion and complete fire extinguishing

(2) The fine water mist fire extinguishing device, the fine water mist mainly achieves fire extinguishment by isolating oxygen, but if a fire occurs in the battery box, the fine water mist cannot enter the battery box, and the oxygen of the fire source cannot be isolated, so the fire extinguishment cannot be achieved

(3) The water spray fire extinguishing device requires a large amount of water to completely immerse the batteries in the energy storage cabinet. Although the fire can be extinguished, the batteries in the energy storage cabinet are completely submerged in water and cannot be used any longer, resulting in great waste

(4) Fire detection tube type fire extinguishing device, there are many battery boxes in the energy storage cabinet, if the fire detection tube passes through all the battery boxes, limited by the application length of the fire detection tube, almost every battery cluster needs to install a fire detection tube Type fire extinguishing device, the amount of consumption is large, it cannot be integrated design, and the fire detection tube is easy to age during long-term use, resulting in failure of the fire extinguishing device or leakage of fire extinguishing agent, making it impossible to reliably extinguish the fire
