Example Embodiment

[0018]The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019]Such asfigure 1As shown, the carbon dioxide fire extinguishing device of the present invention can be roughly divided into five parts:

[0020]1. Storage tank part

[0021]The carbon dioxide storage tank 1 is composed of a cylinder, a head, a half pipe jacket, a saddle, a heat preservation and each connecting pipe port. The temperature of the storage tank during normal operation needs to be controlled between 15~25℃, and the maximum working pressure is 6.5Mpa. It will only appear at a low temperature of -30℃ for a short time during refilling, and the pressure at low temperature is only about 1.5MPa, which is consistent with The “low temperature and low stress conditions” specified in GB 150.3 do not have to follow the regulations on low temperature storage tanks. And the main body material does not need to use low-temperature resistant stainless steel materials, just u...

Abstract

The invention relates to a novel carbon dioxide extinguishing device for fire protection. An ordinary carbon dioxide gas storage tank is low in storage temperature and pressure and low in gas outlet speed, carbon dioxide cannot be stored for a long time, and it is difficult to achieve the purpose of extinguishing for fire protection. The novel carbon dioxide extinguishing device comprises a storage tank; carbon dioxide in a liquid mixed state is stored in the storage tank; a temperature control system, a pressure control system, a safety relief device and a liquid level monitoring system are connected to the outer side of the storage tank; the temperature control system and the pressure control system comprise a high-temperature and low-temperature integrated machine capable of adjusting the temperature of the storage tank; and the temperature control system, the pressure control system, the safety relief device, the liquid level monitoring system and the high-temperature and low-temperature integrated machine are connected with a control cabinet. The novel carbon dioxide extinguishing device has the following advantages: 1, medium-pressure storage can meet the requirements for large gas output in use; 2, pipelines can be laid in a factory, and one storage tank can meet the extinguishing requirements of a plurality of factories; 3, the systems can carry out intelligent monitoring, and the manual monitoring time can be shortened; and 4, the manufacturing and maintenance cost of the storage tank is low.

Description

technical field [0001] The invention relates to the technical field of fire fighting, in particular to a novel carbon dioxide fire extinguishing device for fire fighting. Background technique [0002] Nowadays, there are many types of fire extinguishing materials, such as: commonly used water, sand, fire blankets, dry powder, high-expansion foam, and carbon dioxide. Different fire extinguishing methods are suitable for different scenarios, among which carbon dioxide is suitable for fire extinguishing in many occasions, and can be used for extinguishing most electrical equipment fires. It is a very common fire extinguishing material. [0003] However, the current carbon dioxide fire extinguishing devices are either small portable fire extinguishers with a limited fire extinguishing area; or mechanical carbon dioxide liquid tanks for large fire alarms, but when the fire trucks arrive at the scene, they often miss the best time to extinguish the fire. The carbon dioxide liquid...
