Description

Technical Field

[0001] The present invention relates to the technical field of tunnel safety equipment, and in particular to a smoke suppression and air purification system for ensuring safe escape from tunnel fire. Background Art

[0002] After a fire occurs in a highway tunnel, a large amount of high-temperature harmful smoke and haze will be quickly generated. In the absence of wind or light wind in the tunnel, the laminar diffusion rate of the smoke and haze to the entrance and exit is 0.8-1.2m / s, and the diffusion rate from the top of the tunnel to the road surface is greater than 3.2m / min; if the wind speed is high, the laminar state of the smoke and haze will be disrupted, and the smoke and haze will quickly spread and fill the tunnel space; the spread of toxic smoke and haze will increase the difficulty of escape and rescue. The main cause of casualties in highway tunnel fires is the suffocation of people caused by the accumulation of a large amount of thick smoke. Therefore, ensuring the air quality within the height range of people is an important measure for safe escape from fires.

[0003] In the prior art, jet fans are often used to ventilate the tunnel environment. However, jet fans have high energy consumption (tens of kilowatts), a small operating range, and poor smoke treatment effects, which are not conducive to long-term use.

[0004] Therefore, there is a need for a smoke suppression and air purification system that has low comprehensive energy consumption and can efficiently and quickly (within 15 minutes) reduce the toxic smoke concentration and visual distance within the height range of personnel, thereby ensuring the safe escape of personnel from tunnel fires.

DETAILED DESCRIPTION

[0065] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0066] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0068] Embodiment 1

[0069] like Figures 1 to 3 As shown, the smoke suppression air purification system for ensuring safe escape from tunnel fires in this application includes two rows of purifiers 001 positioned in the tunnel; the purifiers 001 are negative ion smoke purifiers, which are prior art;

[0070] Two rows of purifiers 001 are symmetrically or staggeredly arranged along the length of the tunnel at the arch angles where the tunnel arch wall and the inspection road meet on both sides of the tunnel road surface, ensuring air purification in the tunnel under normal conditions; the spacing between purifiers 001 in the same row is 5 to 15 meters;

[0071] Further, such as Figures 4 to 6 As shown, the purifier 001 includes a basic carrier shell 100 and a negative ion release component; the basic carrier shell 100 is a block-shaped shell as a whole, with a mounting hole at the bottom for easy installation, and a rectangular groove at the top for bearing; the negative ion release component includes a carrier 210, a negative ion release needle 220, a power module 230, and a release needle protection cover 240; the carrier 210 is a horizontally arranged rectangular hard plate, which can be detachably fixed in the groove on the top surface of the basic carrier shell 100, and plays the role of carrying the negative ion release needle 220; the negative ion release needle 220 is arranged in multiple rows, all arranged longitudinally; The source module 230 (including a transformer, a rectifier, a voltage stabilizer, etc.) is electrically connected to the negative ion release needle 220, and plays the role of supplying electrical energy and boosting the current (having the ability to increase 22V AC power to a specified voltage strength for output); when in use, the DC high voltage generates a high corona, and a large number of electrons are released at high speed by using the tip of the negative ion release needle 220, which combine with oxygen molecules in the air to generate air negative ions; the release needle protection cover 240 is fixed on the basic carrier shell 100, and is used to cover the negative ion release needle 220 to prevent it from being damaged (protecting the negative ion release needle 220 from being damaged by external forces).

[0072] Preferably, the negative ion releasing needles 220 are arranged in three rows.

[0073] Negative ions carry negative charges. When they move in the air, they collide and combine with neutral or positively charged dust, smoke and other particles, making them negatively charged. Negatively charged particles will move toward the dust collecting electrode (wall or ground) under the action of electric field force and gravity, thereby achieving the purpose of smoke and dust removal. Purifier 001 can release negative ions of different concentrations according to the voltage, and quickly decompose, adsorb and accumulate harmful dust and haze in a spherical space with a radius of 2m to 8m, thereby preventing the harm of harmful haze in the space and ensuring that the air in the effective height space is not polluted by a large amount of haze. The power of purifier 001 is 3 to 10W, and the negative ion release amount is 2.0×108 to 5.0×108 (pieces / cm 3 ).

[0074] The experimental data reflecting the processing capacity of the smoke suppression air purification system for ensuring safe escape from tunnel fires are shown in Table 1. Figure 7 and Figure 8 shown.

[0075] Table 1 PM2.5 and PM10 concentration test data table at 2m above the road surface and 2m outside the fire source in the tunnel. The unit in the table is ug / m 3

[0076]

[0077] Furthermore, the smoke suppression and air purification system to ensure safe escape from tunnel fires also includes an air quality detector, which detects the air quality in the tunnel in real time. When in use, the power of the purifier 001 is adjusted in real time according to the air quality data, and the operation and damage of the tunnel's special smoke and haze suppression air purifier are monitored in real time.

[0078] After the fire is discovered by the tunnel monitoring, the relevant components are controlled and the relevant personnel are notified to extinguish the fire. At the same time and after the fire is extinguished, the purifier 001 is turned on to purify the tunnel air.

[0079] Furthermore, the purifier 001 has a built-in fan system and a filtration system. The fan system is used to assist the diffusion of negative ions, and the filtration system is a HEPA filter or an activated carbon filter, which is used to further purify the air and remove particulate matter and harmful gases.

[0080] During tunnel operation, there is no need to use traditional fans. Purifier 001 is used to ensure that the air in the tunnel is clean and pure. The air quality can reach an excellent level in real time. The energy consumption per kilometer per day in the tunnel is less than 76.8kwh / km, which saves more than 82.93% of energy compared to jet fans.

[0081] The power of each purifier 001 does not exceed 10W; assuming that a purifier 001 is arranged every 5m and arranged symmetrically, the total power of each kilometer of tunnel is 396*10=3.96kW; and setting up a jet fan for each kilometer of tunnel requires tens of kilowatts, which greatly reduces ventilation energy consumption during long-term operation.

[0082] According to Shanghai's "Urban Natural Ventilation Underground Road Engineering Design Standard" DG / TJ 08-2386-2021, the impact of underground road fires on personnel safety is mainly reflected in the visibility, temperature and smoke toxicity in the underground road; based on the domestic and foreign indicators for the safe evacuation of personnel under fire conditions, this standard stipulates the environmental characteristic parameters that meet the safe evacuation of personnel under fire conditions in underground roads, and takes the minimum clear height in underground roads as 2m. Among them, according to the safety evaluation standard, if the visibility at a height of 2m in the underground road is less than 10m, it is considered to be in a dangerous position. When a fire occurs, its products are complex and changeable, which is closely related to the type of combustion material and the environment in which it is located. Therefore, it is very difficult to predict the composition and concentration of fire products. In engineering design, an effective simplification method is often used: if the visibility in the underground passage is not less than 10m, it can be regarded that the concentration of various toxic combustion products represented by CO will not reach the tolerance limit of the human body within 30 minutes. After the fire broke out, when the air cleaning system of the present application was not turned on, the visibility in the tunnel was less than 10 meters within 10 minutes. When the air cleaning system of the present application was turned on, the visibility within the 2m height range of the tunnel was higher than 10 meters.

[0083] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0084] The invention solves the technical problems in the prior art that the tunnel air purification system has high energy consumption and has poor smoke treatment effect within the human height range when a fire occurs, which is not conducive to the escape of personnel. The invention achieves the technical effect that the smoke suppression air purification system has low comprehensive energy consumption and can efficiently and quickly reduce the toxic smoke concentration and visual distance within the human height range, thereby ensuring the safe escape of personnel.
