Description

Automatic detection of fire extinguishers

The present invention relates to an automatic detection fire extinguisher, in particular to a fire extinguisher that can predict whether it is suitable for use at ordinary times, and can automatically detect the occurrence of a fire. The fire extinguishing program will be activated at 70°C in the initial stage of the fire, and the alarm can be automatically activated. It can automatically notify the police and fire suppression unit, the property owner, and the security management unit to automatically and quickly extinguish the fire when the fire occurs. This can not only avoid the loss of personnel and property, but also can according to the large-scale fire accident after the fire accident is dealt with. The data stored in the data database really understands everything that happened during the review of the fire, and because foam is used to extinguish fires, it will not cause pollution and harm to the environment and the human body. It is easier and more convenient to clean up, and it is more convenient and long-term. It is an innovative designer of automatic detection fire extinguishers with more practical and functional characteristics in their overall implementation and use.

Press, the occurrence of combustion requires the existence of the four major elements of "oxygen", "fuel", "temperature" and "chain reaction", and the fire progress of a building varies depending on the structure of the building, making it roughly predictable by the structure of the building The shape after the fire, and it is caused by the fire The size of the opening in the room affected by the disaster, the type of walls surrounding the room, and the amount of combustible materials in the room, etc., can roughly determine the temperature and duration of the fire.

Please refer to the general indoor fire temperature and time change graph shown in Figure 5. Assuming that without any restrictions, the combustion development process of a typical indoor fire can generally be divided into four stages:

A. Initial stage: The power cord is smoldering. When the temperature reaches 70 degrees, smoke and peculiar smell will be generated. The smoke detector will sound an alarm, the breaker will trip, and a fire will start to occur.

B. Growth stage: The temperature can rise above 70 degrees and smoke rises steeply to between 800 and 100 degrees, resulting in a flash explosion point.

C. Heyday stage: The fire reaches the flash point, and continues to release a large amount of heat and high temperature, and the temperature rises sharply to above 800 degrees to 1000 degrees. A large amount of poisonous gas and smoke are produced, which is not suitable for the survival of personnel.

D. Recession phase: The fire gradually dies out as residual ashes.

The critical time point for the fire to be eliminated is before the fire reaches the flash fire, that is, when the temperature is between 100 degrees and 200 degrees, and the temperature has not risen to 800 to 100 degrees, and this period of time occurs when the temperature is 70 degrees. Before the peculiar smell, the fire is about to start, and it takes less than 2 minutes, and when the peculiar smell occurs when the temperature reaches 70 degrees from the point of the fire, the smoke alarm can give an alarm to warn the personnel to put out the fire or leave the scene as soon as possible. Time is often too late.

The existing fire extinguishers are generally dry powder fire extinguishers. The main component is ammonium dihydrogen phosphate [NH ₄ H ₂ PO ₄ ], and silica, silicone resin, etc. are added to inhibit and suffocate, and can quickly extinguish fires.

However, although the above dry powder fire extinguisher can achieve the expected effect of extinguishing fire, it has also been found in its actual operation and use that it has the following shortcomings:

1. When the dry powder fire extinguisher is used, the dust produced by it will be dispersed with the wind, which will not only pollute the air and the environment, but also be easily inhaled by the human body and cause lung damage.

2. In use, the dry powder fire extinguisher is only simply covering the fire point, which is not only inconvenient in operation and use, and the fire is prone to re-ignition.

3. The temperature of the dry powder installed in the dry powder fire extinguisher should not be too high during storage, otherwise it will deteriorate, and the storage period is short, and it is easy to be damp and agglomerate, making it unusable.

4. When the dry powder fire extinguisher is used, the dust produced will pollute the equipment, production materials, and finished products. It will not only slightly corrode the equipment, production materials, and finished products, but it is also extremely difficult to remove and restore, and it will cause great loss of property. .

5. When the dry powder fire extinguisher is used in an apartment building, because of the spreading process of a fire on any one of the floors, the next fire point is often the ceiling of the top floor, and because of the weight of the dry powder fire extinguisher and the weight and airiness of the dust, the height of the ceiling is The fire cannot be extinguished.

The fire source generated by the fire point at a low temperature can automatically and quickly extinguish the fire, making it impossible to expand the fire. Not only can the loss of personnel and property be avoided, but also because the foam used contains a variety of biological protein foams in addition to chemical foams. When encountering high temperature, it can absorb heat and expand to block the air. There are five fire extinguishing methods: suppression, suffocation, blocking, cooling, and covering. It will not cause pollution and harm to the environment and human body. It is easier and more convenient to clean up, and it is more convenient and long-term.
