Description

Technology Field

[0001] The present invention relates to an ESS fire suppression and toxic gas treatment system, and more specifically, to an ESS fire suppression and toxic gas treatment system capable of suppressing fires and treating toxic gases in preparation for fire and explosion accidents that may occur in an energy storage system (ESS). Background Technology

[0002] Energy storage systems (ESS) are primarily used in large-scale solar and wind power complexes to enhance the efficiency of power storage and supply, and play an important role in complementing the intermittency of renewable energy.

[0003] ESS uses lithium-ion batteries as the primary storage medium and consists of cells and modules connected in parallel and series.

[0004] In existing ESS systems, temperature monitoring, overheating prevention devices, and fire extinguishing systems such as sprinklers are used to prevent fire or thermal runaway.

[0005] However, this technology has difficulty effectively blocking the thermal runaway that occurs sequentially inside the battery in the event of a fire, and it cannot completely eliminate the possibility of the fire spreading from the inside to the outside.

[0006] In particular, due to the chemical characteristics of ESS fires, they are difficult to suppress with traditional firefighting methods using water or general fire extinguishers because they involve explosions occurring at high temperatures, and this can actually worsen the situation.

[0007] Therefore, there is a need to develop new technologies that can guarantee safety from ESS fires.

[0008] As a background technology for an invention related to this, Korean Patent Publication No. 10-2024-0012248 (fire suppression type ess container) has been disclosed.

[0009] The disclosed fire suppression type ESS container may be configured to include a container body (A) having an installation space (100) equipped with an ESS (Energy Storage System, 10) and a fire suppression space (200) in which a fire suppression liquid is stored, wherein, in the event of a fire, the ESS (10) or a specific battery rack among the battery stacks constituting the ESS (10) that has caught fire is moved to the fire suppression space (200) and submerged in the fire suppression liquid to suppress the fire. The problem to be solved

[0010] The problem that the present invention aims to solve is to provide an ESS fire suppression and toxic gas treatment system that effectively prevents risks caused by fire and thermal runaway that may occur in an energy storage system (ESS) and minimizes damage to the surrounding environment and infrastructure even if a fire occurs, in order to solve the conventional problems described above.

[0011] The technical problems to be solved by the present invention are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which the present invention belongs from the description below. means of solving the problem

[0012] The ESS fire suppression and toxic gas treatment system of the present invention, as a means of solving the problem for achieving the above objective, comprises: a lift that detects a fire generated in the ESS and transports it to a fire suppression space; a cover that operates when the ESS is transported underground; a fire extinguishing liquid spraying device that sprays a fire extinguishing liquid to suppress the fire within the fire suppression space; a toxic gas suction device that collects toxic gas generated from the fire and transports it to a central processing device; and a discharge device that purifies the toxic gas transported through the toxic gas suction device and discharges it to the outside.

[0013] In addition, the fire suppression space is an underground space formed below ground level, and the ESS is placed on a support plate and can move into the underground space, thereby providing an ESS fire suppression and toxic gas treatment system.

[0014] In addition, the ESS fire suppression and toxic gas treatment system is provided, characterized in that the support plate can be raised and lowered by a hydraulically driven lift. Effects of the invention

[0015] The ESS fire suppression and toxic gas treatment system of the present invention, as described above, can suppress fires quickly and safely by moving the ESS module to an explosion-proof underground space to prevent the spread of fire and explosions and by ensuring stability and reliability through a hydraulic lift method.

[0016] In addition, by purifying toxic gases generated by fire in a central processing unit and safely discharging them, environmental pollution and casualties can be minimized.

[0017] In addition, it is possible to improve the reliability and economic efficiency of the ESS by reducing recovery costs and operational downtime losses caused by accidents.

[0018] In addition, maintenance costs can be reduced due to the system's reusability, enabling support for the stable operation of renewable energy infrastructure.

[0019] And the effects obtainable from the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art to which the present invention belongs from the description below. Brief explanation of the drawing

[0027] <Example>

[0028] Example 1 - When no fire occurs (Fig. 1)

[0029] The battery temperature is maintained normally by the BBMS (Battery Management System) and EMS (Energy Management System) of the ESS (100), and no fire occurs.

[0031] Example 2 - Exaggeration of fire suppression (Figs. 2 and 3)

[0032] When a temperature rise and smoke generation are detected in the ESS (100), the hydraulic lift (200) can be operated to move the ESS (100) to the fire suppression space (300). After the lift (200) is lowered, the cover (400) is automatically closed, and a seal can be made between the ESS (100) and the ground.

[0033] In addition, a fire extinguishing agent can be sprayed from the fire extinguishing agent spraying device (320) to suppress the fire in the ESS (100). The spraying position of the fire extinguishing agent spraying device (320) is arranged to surround the ESS (100) 360 degrees, and the flames generated by spraying from multiple angles can be effectively suppressed.

[0035] Example 3 - Toxic gas treatment process (Fig. 7)

[0036] Toxic gases generated by a fire can be transferred to a central processing unit (600) through a toxic gas intake device (500), and the toxic gases transferred to the central processing unit (600) can be purified and then discharged to the outside through an air external discharge device.

[0038] Example 4 - Recovery process for reuse (Figs. 5 and 6)

[0039] When the fire in the ESS (100) is extinguished and the toxic gas is purified, the hydraulic lift (200) can be raised to transport the ESS (100) module back to the ground.

[0041] According to an embodiment of the present invention, an ESS fire suppression and toxic gas treatment system is provided, comprising: a lift (200) that detects a fire generated in the ESS (100) and transports it to a fire suppression space (300); a cover (400) that operates when the ESS (100) is transported underground; a fire extinguishing liquid spraying device (320) that sprays a fire extinguishing liquid to suppress the fire within the fire suppression space (300); a toxic gas suction device (500) that collects toxic gas generated from the fire and transports it to a central processing device (600); and a discharge device that purifies the toxic gas transported through the toxic gas suction device (500) and discharges it to the outside.

[0042] The ESS fire suppression and toxic gas treatment system according to the present invention will be described in detail with reference to the attached drawings.

[0043] As shown in FIGS. 2, 3 and 7, the ESS fire suppression and toxic gas treatment system of the present invention may be configured to include an ESS (100), a lift (200), a fire suppression space (300) including a blast-proof wall (310), a fire extinguishing liquid spraying device (320), a cover (400), a toxic gas suction device (500), a toxic gas central treatment device (600), and a purified air external discharge device (610).

[0044] The above ESS (100) is an abbreviation for Energy Storage System, and refers to a device that stores energy and supplies energy when needed.

[0045] The above ESS (100) may be composed of a battery module, a power conversion device (PCS), a battery management system (BMS), and an energy management system (EMS), and may be used to supplement the irregular production of renewable energy, or to stabilize the power grid and improve the efficiency of electricity usage.

[0046] Figure 1 is a drawing showing the ESS (100) placed on the ground.

[0047] FIG. 4 shows the individual appearance of the ESS (100) in the arrangement of the ESS (100) of FIG. 1, and each ESS (100) can be positioned on a net-type support plate.

[0048] When the temperature of the internal cell of the ESS (100) rises, the sensor of the BMS or EMS of the ESS (100) can detect the rise in temperature. At this time, if the temperature of the internal cell of the ESS (100) rises above a preset temperature, the lift (200) installed for each ESS (100) lowers and transports the ESS (100) to the fire suppression space (300).

[0049] The above support plate can perform the function of supporting the lower side of the ESS (100) while attached to the lift (200).

[0050] As illustrated in FIG. 8, the lift (200) can be applied in various forms and ways, and it is preferable to apply a hydraulic lift (200) capable of withstanding a large load.

[0051] Additionally, it is possible to change the height of the lift by adjusting the angle between multiple lift legs (220). The electric motor for driving this can be located inside the fire suppression space (300) or on the ground.

[0052] As in Example 2 and FIG. 3, when the lift (200) is lowered, the cover (400) shown in FIG. 5 and FIG. 6 is operated to prevent flames and toxic gases from the fire from leaking out to the ground. At this time, the operation method of the cover (400) can be driven in various ways, and in the embodiment of the present invention, a slide-type cover (400) is adopted.

[0053] In addition, the material of the cover (400) is preferably made of an insulating material to withstand the flames and heat of an explosion, and it is also preferable to have a hole (410) to allow the wires connected to the ESS (100) to pass through so that the wires are not severed due to fire.

[0054] It is desirable that the various wires connected to the above ESS (100) be designed with sufficient length to account for the ESS (100) moving underground.

[0055] As shown in Example 2 and FIG. 3, when the lift (200) is lowered, a fire extinguishing agent is sprayed using a fire extinguishing agent spraying device (320). At this time, the fire extinguishing agent may be purified water, and may include a non-conductive fire extinguishing agent effective in suppressing battery fires.

[0056] In addition, the fire extinguishing liquid spraying device (320) can be configured in various forms, and it is preferable to have it in the form of a nozzle as in the embodiment of the present invention.

[0057] And, the tank provided for spraying the fire extinguishing liquid can be installed in the fire suppression space (300), on the ground, and in a separate space.

[0058] According to Example 3 and FIG. 7, toxic gases generated by a fire can be sucked in through a toxic gas suction device (500). At this time, the toxic gas suction device (500) may be provided in various forms, and it is preferable to capture the toxic gases by configuring it in a suction fan manner.

[0059] The above toxic gas can be moved to a central processing unit (600) through a pipe connected to a toxic gas intake device (500). The central processing unit (600) may be configured to include a HEPA filter for removing particles, an activated carbon filter for chemical adsorption, a scrubber system for chemical neutralization, and a catalytic oxidation device for a superma reaction.

[0060] The above HEPA filter can capture smoke and fine particles generated by fire, and the above activated carbon filter can remove toxic compounds through chemical adsorption.

[0061] In addition, the scrubber system can neutralize the gas using an acidic or alkaline chemical scrubber, and the catalytic oxidation device can decompose the remaining harmful gas into carbon dioxide and water.

[0062] In addition, as shown in Example 3 and FIG. 7, the purified air can be discharged to the outside through a purified air external discharge device (610) that discharges the purified air to the outside. At this time, it is preferable to have a sensor capable of monitoring the concentration of harmful substances in real time for residual gas inspection.

[0063] According to Example 4 and Fig. 4, the ESS (100), after fire suppression and toxic gas treatment are completed, can be raised back to the ground using the lift (200) for normal operation.

[0064] The cover (400) that was closed can be opened again so that the ESS (100) can be raised to the ground, and the deposits such as the sprayed fire extinguishing agent can fall into the fire suppression space (300) through a net-type support plate.

[0065] As described above, the ESS fire suppression and toxic gas treatment system of the present invention can effectively suppress the fire by using a lift (200) to move to the fire suppression space (300) when a fire occurs in the ESS (100), and at the same time, the cover (400) is operated to block the fire and toxic gas spreading to the outside, and by spraying a fire extinguishing agent through a fire extinguishing liquid spraying device (320). In addition, various toxic gases generated during a fire can be effectively treated through a toxic gas suction device (500) and a central processing device (600), thereby significantly improving safety and efficiency regarding fire occurrence compared to conventional technology.

[0066] The foregoing description has broadly detailed the features and technical advantages of the present invention to better facilitate a better understanding of the claims of the invention to be described below. Those skilled in the art will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
