Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to a gas-liquid perfluorohexanone fire extinguishing device. Background Art

[0002] Perfluorohexanone is a clear, colorless, and odorless liquid, pressurized with nitrogen, and stored in a high-pressure gas cylinder as part of a fire extinguishing system. Typical application scenarios include: computer rooms, data centers, aviation, ships, vehicles, libraries, oil and gas production, etc.

[0003] However, the boiling point of perfluorohexanone is relatively low. Perfluorohexanone starts to vaporize at about 30°C and is completely vaporized at 50°C. In the daily working environment in summer, perfluorohexanone in the high-pressure gas cylinder is in a state of coexistence of gas and liquid.

[0004] In the prior art, a liquid pump is usually installed on the high-pressure gas cylinder to deliver perfluorohexanone in the high-pressure gas cylinder to the fire point. On the one hand, only the operation of the liquid pump cannot output gaseous perfluorohexanone and cannot deliver gaseous perfluorohexanone to the fire point, reducing the cooling and fire extinguishing efficiency. On the other hand, two pump bodies, namely a liquid pump and a gas pump, can be installed on one high-pressure gas cylinder at the same time, but this will increase the cost of the overall fire extinguishing device. Summary of the Utility Model

[0005] In view of the above problems, the utility model provides a gas-liquid perfluorohexanone fire extinguishing device, aiming to ensure the cooling and fire extinguishing efficiency and reduce the installation cost of the fire extinguishing device.

[0006] In order to achieve the above invention purpose, the technical scheme adopted by the utility model is as follows:

[0007] Provide a gas-liquid perfluorohexanone fire extinguishing device, including: a cylinder body for storing perfluorohexanone; a gas pump; a first pipeline, one end of which is connected to the cylinder body and the other end is connected to the air inlet of the gas pump; a second pipeline, connected to the air outlet of the gas pump and extending towards the fire point; a third pipeline, one end of which is connected to the cylinder body and the other end is connected to the second pipeline; a fourth pipeline, connecting the outside atmosphere and the cylinder body; the gas pump can deliver gaseous perfluorohexanone to the fire point through the second pipeline, and can also accelerate the air flow rate at the connection of the third pipeline and the second pipeline, so as to reduce the pressure at the nozzle of the third pipeline and deliver liquid perfluorohexanone to the fire point.

[0008] Furthermore, the fire extinguishing device further includes: a valve body disposed on the second pipeline and the third pipeline for controlling the opening and closing of the second pipeline and the third pipeline; a check valve disposed on the fourth pipeline.

[0009] Further, the fire extinguishing device further includes: a nozzle disposed at one end of the second pipe away from the gas pump.

[0010] Further, the air inlet of the first pipe is at the top of the bottle body, and the liquid inlet of the third pipe is at the bottom of the bottle body.

[0011] Further, the fire extinguishing device further includes a float level gauge disposed inside the bottle body.

[0012] The beneficial effects of the present utility model are as follows: The gas pump can transport gaseous perfluorohexanone to the fire point through the second pipe, and can also accelerate the air flow rate at the connection of the third pipe and the second pipe, thereby reducing the pressure at the nozzle of the third pipe and transporting liquid perfluorohexanone towards the fire point; only one gas pump needs to be installed on one bottle body to output gaseous and liquid perfluorohexanone in the bottle body, without adding a liquid pump, which ensures the cooling and fire extinguishing efficiency at the fire extinguishing point while reducing the installation cost of the overall fire extinguishing device.

[0015] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the drawings of the specification and specific embodiments.

[0016] Refer to Figure 1 As shown, the embodiment of the present application discloses a gas-liquid perfluorohexanone fire extinguishing device, including: a bottle body 1 for storing perfluorohexanone; a gas pump 2; a first pipe 31 with one end connected to the bottle body 1 and the other end connected to the air inlet of the gas pump 2; a second pipe 32 connected to the air outlet of the gas pump 2 and extending towards the fire point; a third pipe 33 with one end connected to the bottle body 1 and the other end connected to the second pipe 32; a fourth pipe 34 connected to the outside atmosphere and the bottle body 1; the gas pump 2 can transport gaseous perfluorohexanone to the fire point through the second pipe 32, and can also accelerate the air flow rate at the connection of the third pipe 33 and the second pipe 32, thereby reducing the pressure at the nozzle of the third pipe 33 and transporting liquid perfluorohexanone towards the fire point.

[0017] In specific use, when it is necessary to output perfluorocyclohexanone towards the ignition point, the gas pump 2 is started. On the one hand, the gas pump 2 directly conveys gaseous perfluorocyclohexanone towards the ignition point through the first pipeline 31 and the second pipeline 32. On the other hand, while the gaseous perfluorocyclohexanone flows in the second pipeline 32, according to Bernoulli's principle, it can be known that the air flow rate at the connection of the third pipeline 33 and the second pipeline 32 can also be accelerated, thereby reducing the pressure at the nozzle of the third pipeline 33. The pressure at the nozzle of the third pipeline 33 is less than the atmospheric pressure, and the outside atmosphere enters the bottle body 1 through the fourth pipeline 34 and presses the liquid perfluorocyclohexanone into the third pipeline 33. The liquid perfluorocyclohexanone is conveyed into the second pipeline 32 through the third pipeline 33, and the gaseous perfluorocyclohexanone in the second pipeline 32 carries the liquid perfluorocyclohexanone towards the ignition point for conveyance.

[0018] In the present utility model, only one gas pump 2 needs to be installed on one bottle body 1, and gaseous and liquid perfluorocyclohexanone in the bottle body 1 can be output simultaneously, without the need to install a liquid pump. While ensuring the cooling and fire extinguishing efficiency at the fire extinguishing point, the installation cost of the overall fire extinguishing device is reduced.

[0019] Preferably, the fire extinguishing device further includes: a valve body 4, arranged on the second pipeline 32 and the third pipeline 33, for controlling the opening and closing of the second pipeline 32 and the third pipeline 33. The valve body 4 can be selected as an electromagnetic valve, and the opening and closing of the second pipeline 32 and the third pipeline 33 can be controlled by controlling the on-off of the electromagnetic valve; a check valve 35, arranged on the fourth pipeline 34, only allowing the outside atmosphere to enter the bottle body 1 to prevent backflow.

[0020] It is worth mentioning that high-pressure nitrogen can also be filled in the bottle body 1. When perfluorocyclohexanone is output, the nitrogen expands, thereby improving the conveyance efficiency of perfluorocyclohexanone.

[0021] Furthermore, the fire extinguishing device further includes: a nozzle 5, arranged at one end of the second pipeline 32 far from the gas pump 2, and perfluorocyclohexanone is output through the nozzle 5 to increase the coverage area of perfluorocyclohexanone.

[0022] Furthermore, the air inlet of the first pipeline 31 is at the top of the bottle body 1, and the liquid inlet of the third pipeline 33 is at the bottom of the bottle body 1. Gaseous perfluorocyclohexanone is output at the top of the bottle body 1 through the first pipeline 31, and liquid perfluorocyclohexanone is conveyed at the bottom of the bottle body 1 through the third pipeline 33, improving the conveyance efficiency of gaseous and liquid perfluorocyclohexanone.

[0023] Furthermore, the fire extinguishing device further includes a float level gauge, arranged in the bottle body 1, to know the storage amount of perfluorocyclohexanone in the bottle body 1 through the float level gauge. The staff can conduct regular inspections and make timely supplements to ensure that the fire extinguishing device can operate normally.
