Description

Suction type fire extinguisher

The present invention relates to a fire extinguishing device, and particularly to a suction type fire extinguisher.

According to the press, the conventional spray type fire extinguishing equipment mostly sprays fire extinguishing agents as a fire extinguishing means, among which the fire extinguishing agents include foam, dry powder, carbon dioxide and the like. And because laboratories or industrial plants often involve substances with small specific gravity, such as chemicals and organic solvents, when these materials with low specific gravity cause a fire, if you use conventional spray-type fire extinguishing equipment to extinguish a fire, it will cause fire. The fire extinguishing effect was poor or caused irreparable losses.

Furthermore, when the fire extinguishing agent is foam, it cannot effectively extinguish the small specific gravity material, but it will spread the small specific gravity material and cause the fire to expand. When the fire extinguishing chemical is dry powder, it can extinguish the fire source more effectively. However, the dry powder will cause damage to the experimental equipment and cause great losses to the owners. When the fire extinguishing agent is carbon dioxide, it is based on anoxic extinguishing, which makes firefighters face greater safety risks.

According to this, it is extremely lacking a fire extinguishing device with both safety and high fire extinguishing efficiency.

When the pressure regulating part makes the pressure of the internal space negative, a The external fire source is guided into the suction part by the negative pressure and is sucked into the hollow body part.

Wherein, the pressure regulating unit further includes an air-exhausting device provided on the hollow body to make the pressure in the internal space into a negative pressure state,

In order to avoid damage to the inside of the hollow body due to excessive pressure, the pressure regulating unit further includes a pressure relief device provided on the hollow body so that the pressure in the internal space is not higher than a predetermined pressure.

In one embodiment of the present invention, the suction unit further includes a heat insulation pipe, the hollow body is connected at one end, a suction port is provided at the other end of the heat insulation pipe, and the suction port is It is preferable that the diameter is smaller than the diameter of the heat insulation pipe.

Furthermore, in order to keep the internal space in an anoxic state and to block the external fire source from oxygen after entering the internal space, the inhaled fire extinguisher disclosed in the present invention further includes an oxygen absorbing part. It is provided in the internal space and / or the suction part.

For example, the oxygen absorbing portion is disposed in a portion of the heat insulation pipe close to the internal space.

In order to prevent soot in the internal space or the external fire source from entering the pressure regulating section, another embodiment of the present invention further includes an isolation section provided between the internal space and the pressure regulating section for blocking. A substance enters the pressure regulating part from the internal space.

For example, the insulation system may be a fireproof net, or may include a fireproof material and a filter material, such as fireproof cotton and activated carbon.

In order to increase the safety of use, the inhaled fire extinguisher disclosed in the present invention further includes a heat insulation part provided on the outer surface of the hollow body part.

The invention discloses an inhalation type fire extinguisher, which introduces an external fire source into an oxygen-deficient environment by inhalation, and isolates the external fire source from combustion conditions such as oxygen, so as to reach a rapid fire extinguishing source and prevent the fire from spreading. Effect.

Among them, the external fire source can be substances such as chemicals, organic solvents, and oils.

In order to illustrate the present invention and its effects, one embodiment of the present invention will be described below in conjunction with the drawings to make a more detailed description as follows.

Referring to the first figure, an inhaled fire extinguisher (10) according to an embodiment of the present invention mainly includes a hollow body portion (20), an inhalation portion (30), a pressure regulating portion (40), and an oxygen inhalation portion ( 50), an insulation part (60) and an insulation part (70), wherein:

The hollow body (20) is made of explosion-proof and heat-insulating material, and has an internal space (21).

The suction part (30) includes a heat-insulating tube (31), which is expandable, and the hollow body part (20) is connected at one end, and a suction port (32) is formed in a flat shape and is provided in the The other end of the heat insulation pipe (31), and the suction area of the suction port (32) is smaller than the cross-sectional area of the heat insulation pipe (31).

The pressure regulating part (40) includes an air extraction device (41), which is arranged on the hollow body (20) and communicates with the internal space (21). When the air extraction device (41) is activated, it will The air in the internal space (21) is exhausted, so that the pressure in the internal space (21) becomes a negative pressure state. A pressure relief device (42) is provided on the hollow body (20) to communicate with the internal space (21). ) Are connected. When the pressure of the internal space (21) is greater than a predetermined pressure value, the pressure relief device (42) lowers the pressure of the internal space (21) below the predetermined pressure value.

Specifically, the air extraction device (41) has a power source (411) and an air suction pipe (412), one end of which is connected to the power source (411), and the other end is connected to the internal space (21).

The oxygen absorbing part (50) contains an oxygen absorbing agent, and is arranged in the inner wall of the hollow body part (20) and the pipe wall of the heat insulation pipe (31).

The isolation portion (60) is provided between the internal space (21) and the pressure regulating portion (30) to prevent substances in the internal space (21) from entering the pressure regulating portion (30). Specifically, the The insulation part (60) includes a fire prevention net (61), which is arranged at one end of the exhaust pipe (412), a fireproof foam (62) and an activated carbon (63) are filled in the exhaust pipe (412).

The heat insulation layer (70) is wrapped on the outer surface of the hollow body (20).

With the composition of the above components, when the suction part (30) is close to the external fire source, the suction type fire extinguisher (10) disclosed in the present invention can make the hollow body ( 20) The internal pressure becomes a negative pressure state, and the external fire source will be sucked into the internal space (21) due to the air flow generated by the pressure difference between the inside and outside of the hollow body (20), and pass through the oxygen absorption portion The function of (50) absorbs external oxygen and maintains an anoxic state in the internal space (21). Therefore, when the external fire source enters the internal space (21), it can not only remove external oxygen, but also effectively Ground to prevent its contact with oxygen, can achieve the effect of rapid fire extinguishing.

Furthermore, there may be smoke and dust in the internal space (21), and when the external fire source has just entered the internal space (21), the smoke and dust will be in a burning state. Therefore, through the insulation portion ( 60) It is located in the air extraction device (41), which can not only prevent the smoke from continuing to burn, but also absorb the smoke, so as to avoid the damage of the smoke or reduce the fire extinguishing effect of the inhalation fire extinguisher disclosed in the present invention.

In addition, when the suction fire extinguisher (10) disclosed in the present invention is continuously sucked, the pressure of the internal space (21) will be caused due to the continuous increase of the external fire source entering the internal space (21) and the combustion of smoke and dust. Rise, and the continuous high pressure of the internal space (21) will cause the hollow body (20) to face a high risk of damage, which will also pose a threat to the user's safety, so through the setting of the pressure relief device (42), The pressure relief procedure can be performed when the internal pressure is too high to maintain the pressure of the internal space (21) within a safe range.
