Description

TECHNICAL FIELD

[0001] The present application belongs to the field of fire smoke control, and in particular, relates to a zero-energy intelligent smoke rapid elimination device and method. BACKGROUND

[0002] In many fire cases, the thick smoke produced by the fire is the first killer that takes people's lives, rather than the direct weapon of the raging fire. More than 80% of people who die in fires die of smoke asphyxiation. The harm of smoke mainly comes from its toxicity and small particle smoke dust. After a fire occurs, the temperature of the thick smoke produced by the fire can reach 700℃, which can burn the skin and cause the high-temperature smoke inhaled into the body to burn the nasal cavity, throat, organs, etc., causing the victim to suffocate and die. The thick smoke reaches before the fire does, especially in high-rise buildings. Under the dual effects of buoyancy and chimney effect, the high-temperature gas produced by the fire continuously accumulates at the top of the channel. At the same time, the spread of smoke is much faster than the spread of fire. Smoke can be said to be everywhere, and its spread speed is 5 times faster than that of fire. A fire breaks out on the first floor, and within ten seconds, smoke spreads to the tenth floor, which may cause people to suffocate and die. The flow direction of smoke is the path of fire spread. The thick smoke with extremely high temperature can form a raging fire within 2 minutes, and can also pose a threat to people far away. The thick smoke produced by the fire seriously affects the escape vision, and the rapidly spreading smoke can greatly reduce the escape probability. Therefore, it is of great significance to realize timely monitoring and early warning of public space fires and rapid elimination of smoke in enclosed spaces.

[0003] To reduce the great harm caused by fire smoke, scholars have proposed various smoke control methods, which can be divided into smoke prevention and smoke exhaust methods according to the form. "Smoke prevention" is to prevent the entry of smoke, which is passive, including smoke isolation method, mechanical pressurized air supply system, etc. On the contrary, "smoke exhaust" is to actively change the flow direction of smoke to exhaust it outdoors, which is active, including smoke exhaust fan smoke elimination method, fire water mist smoke elimination method, etc. However, the existing methods have the disadvantages of unstable effect and even further reduced visibility in the fire scene. They cannot well help the trapped personnel in the fire scene to escape, and the threat of fire smoke to the trapped personnel still exists.

[0004] Currently, the related prior art includes:

[0005] (1) A wall-mounted array packaging structure sound wave agglomeration fixed-point smoke elimination device for an escape corridor (patent document CN117046020A) The patent document discloses a wall-mounted array packaging structure sound wave agglomeration fixed-point smoke elimination device for an escape corridor. The disclosed device eliminates fire smoke through a sound wave generation module and a atomizing and spraying module. However, the device has the problem of loud noise.

[0006] (2) A handheld electrostatic smoke elimination device (patent document CN114950729A) discloses a handheld electrostatic smoke elimination device, but the device obtained by this technical solution still needs to be carried into the fire scene by firefighters for operation, which exposes the personnel to risk and cannot respond quickly and timely.

[0007] (3) A portable bipolar corona charging fire extinguishing and smoke elimination device (patent document CN116808482A) discloses a portable bipolar corona charging fire extinguishing and smoke elimination device. The disclosed device sprays different polarity charge mist particles from the claw-shaped electrode at the nozzle to accelerate the adsorption and sedimentation of dust and other particulate matters in the air, but its power consumption is high and there is a discharge safety problem. And the above patent products cannot still operate normally in the case of power failure caused by fire.

[0008] (4) Solar photovoltaic power supply low-temperature plasma purification equipment (patent document CN116036815B) discloses a solar photovoltaic power supply low-temperature plasma purification equipment, but it is not suitable for smoke emergency treatment in high-risk fire scenes. The scheme changes the power supply effect of the pressure changing device by the pressure generated by the expansion medium, which cannot respond quickly and timely, and cannot eliminate a large amount of smoke. And the activated carbon adsorption area of the scheme may be self-ignited in a high-temperature and high-concentration organic environment, especially in a fire scene. The exothermic adsorption and oxidation reaction of activated carbon may accelerate combustion. Activated carbon may catalyze the oxidation and heat release of toxic gases in waste gas in a fire scene, increasing the risk of fire.

[0009] In summary, there are still many technical problems in the current technology for eliminating fire smoke, therefore, it is urgent to find a practical and rapid and effective control means for fire smoke. SUMMARY

[0086] In a more specific embodiment, after the direct current voltage conversion module 8 is turned on, the high-voltage pack in the direct current voltage conversion module 8 is connected to the solar controller 4 to output ultrahigh voltage in the range of 1 to 15 kilovolts, which provides the plasma generator 10 with ultrahigh voltage for stable direct current corona discharge; the integrated direct current plasma generation module 9 is formed by six plasma generators 10 connected in parallel; each plasma generator 10 is connected in series by Figs. 2 to 5The plasma generator 10 includes a housing, a discharge electrode and a grounding electrode, and has a total size of 210mm*160mm*20mm. The housing is an acrylic plate with a thickness of 5mm, the grounding electrode plate is an aluminum plate with a length of 200mm, a width of 40mm, and a thickness of 2mm, and the discharge electrode is a pure tungsten needle electrode rod with a length of 15mm, a diameter of 1.5mm, a needle tip of 2mm, and a needle tip radius of 0.25mm. The discharge electrode of the plasma generator 10 is placed on the upper and lower bottom surfaces of the housing, and the electrode rods on the upper and lower bottom surfaces are perpendicular to the housing, and the needle tips are oppositely placed. The electrode rods on the upper and lower bottom surfaces are arranged at equal distances to avoid discharge interference. The discharge distance between the needle tip of the discharge electrode and the grounding electrode plate is 5-15mm. There are nine discharge electrodes on each bottom surface, which are arranged in two rows. The grounding electrode plate is placed opposite to each row of discharge electrodes. Therefore, each plasma generator has eighteen discharge electrodes connected in series and four grounding electrode plates connected in series. The aperture of the hole punched on the housing of the plasma generator 10 is 1.5mm, which is the same as the diameter of the tungsten electrode rod. Since there are two rows of discharge electrodes on the upper and lower bottom surfaces of the plasma generator, the discharge electrodes of the same plasma generator 10 need to be connected in series.
