Description

A multi-point jet cooling type hot aerosol fire extinguishing device

technical field

The invention relates to the technical field of fire fighting and fire fighting, and more particularly to a multi-point jetting and cooling type hot aerosol fire fighting device.

Background technique

With the development of the times and the continuous advancement of science and technology, aerosol fire extinguishing technology is a new type of fire extinguishing technology developed on the basis of military pyrotechnic technology. For research and development, potassium nitrate is mainly used as the main oxidant in the aerosol generating agent, and its spray has high fire extinguishing efficiency, but because it contains a large amount of potassium ions, it is easy to absorb moisture and form a yellow and sticky strong alkaline. Conductive liquid film, this substance has great damage to electronic equipment, so K-type aerosol automatic fire extinguishing device cannot be used in electronic equipment, precision instruments and cultural relics archives. Aerosol (S-type) mainly uses strontium salt as the main oxidant. Unlike K-type aerosol, strontium ion does not absorb moisture, does not form a conductive solution, and does not cause damage to electrical equipment, which has become more and more widely accepted by users.

To provide a multi-point jet cooling type hot aerosol fire extinguishing device that is not only harmless to the human body, but also has high fire extinguishing efficiency, less amount of fire extinguisher, weight and space saving, environmental friendliness, easy installation, extremely low maintenance cost and cost saving.

Preferably, both the aerosol generating chamber and the outer casing are configured to have a square cross-section.

Preferably, cooling particles are further arranged in the buffer space formed by the aerosol generating chamber and the outer casing, so that when the generated aerosol gas passes through the cooling particles and is sprayed from the nozzle, the effect of effectively reducing the temperature of the nozzle can be achieved.

Preferably, six nozzles are provided on the outer surface of the aerosol generating chamber to form an unobstructed and fast-fixing airway.

Preferably, ten nozzles are also provided on the outer surface of the casing, and after the device is started, it can be quickly fully submerged, and the zero-obstruction fire extinguishing can be covered in all directions.

Preferably, the heat-sensitive wire is a temperature-sensing detection activation wire.

The present invention has achieved the following technical effects with respect to the prior art:

By connecting and fixing the aerosol generating chamber (medicine box) and the aerosol (medicine cake) in the present invention, the aerosol gas path can be changed, thereby reducing the spray flame and reducing the temperature. The heat insulation plate is fixed to the base and the outer casing respectively, so as to reduce the outlet temperature and the casing temperature. The cooling particles are put into the buffer space after they are heavy, so as to achieve the effect of cooling the spraying temperature of the aerosol. The thermal line can be automatically activated by temperature sensing. After the aerosol is activated, it spreads in the fixed airway, and is quickly released into the protective space by the multiple nozzles of the casing, so as to quickly control the fire in a way of full-scale submersion. The device has the advantages of no harm to the human body, high fire-extinguishing efficiency, less amount of fire extinguisher, saving weight and space, being environmentally friendly, easy to install, extremely low maintenance cost and cost saving.
