Embodiment Construction

[0010] Such as figure 1 As shown, when a fire occurs in the coal bunker, the automatic detection and alarm system will send out a fire alarm signal. After receiving the fire alarm signal, the fire extinguishing control system will issue a fire extinguishing control command in an automatic / manual mode. When the command is issued, it will start fire extinguishing after a delay of about 30s The control valve fills the coal bunker with low-pressure carbon dioxide to extinguish the coal bunker fire.

[0011] Such as figure 1 As shown, the sensor of the weighing device is set under the storage tank, and the weight of carbon dioxide in the storage tank is displayed on the controller of the inerting system through transmission. To ensure the amount of carbon dioxide required for fire extinguishing.

[0012] Such as figure 1 As shown, the fire extinguishing control system can accept the fire alarm signal input, that is, it can control the fire extinguishing system automatically or m...

Abstract

The invention discloses a low-pressure carbon dioxide fire extinguishing system of a sealed coal bin and belongs to a fire-extinguishing fire protection device. The low-pressure carbon dioxide fire extinguishing system of the sealed coal bin comprises a low-pressure carbon dioxide storage device, a weighing device, a safety valve, a bypass valve, a fire-extinguishing control valve and an automatic detection and alarm system. The low-pressure carbon dioxide fire extinguishing system of the sealed coal bin has the advantages that alarm signals sent by a fire alarming signal system of the coal bin are received and the fire-extinguishing control valve is opened and closed by a fire-extinguishing control system, thus filling the sealed coal bin with low-pressure carbon dioxide and extinguishing fire for the sealed coal bin.

Description

technical field [0001] The patent of the invention relates to a coal bunker fire extinguishing system, in particular to a closed coal bunker low-pressure carbon dioxide fire extinguishing system, especially suitable for a coal bunker with a large amount of coal stored. It solves the traditional fire fighting needs a lot of manpower and equipment needs. It also prevents personal injury to firefighters when a fire occurs. At the same time, compared with the traditional fire extinguishing method, it reduces a lot of preparation time, thereby reducing a lot of economic losses. Background technique [0002] The closed coal yard is a large-scale device used to store and unload bulk materials conveniently. It is also the main facility used by power plants to store raw coal in recent years. The original coal barrel is a cylindrical structure with a flat top and a conical bottom constructed of reinforced concrete, with a volume of tens of thousands of M. 3 . When a fire broke out...
