Description

Air purification devices and air purification systems applicable at fire scenes

[0001] The present invention relates to an air purification device applicable at a fire scene, and more specifically, to an air purification device and air purification system applicable at a fire scene that purifies air contaminated by toxic gases generated in disaster situations, particularly when a fire occurs, thereby minimizing casualties before emergency rescue.

[0002] In addition, this invention is a project carried out as part of the Industry-Academic-Research Council (MC) support program of the Industrial Cluster Competitiveness Enhancement Project of the Korea Industrial Complex Corporation.

[0003]

[0004] As population density in urban areas persists, the super-high-rise construction of buildings such as apartments and high-rise buildings is continuously taking place.

[0005] Therefore, in the case of high-rise buildings, disaster situations, especially fires, result in significant property damage as well as serious loss of life.

[0006] When a fire occurs in a building, significant casualties result not only from the flames but also from the accompanying toxic gases before emergency rescue can take place.

[0007] For example, victims trapped in a building unable to escape due to a fire inhale toxic gases from the fire, resulting in damage from suffocation by toxic gases, and such suffocation by toxic gases actually causes more damage than the damage caused by the flames.

[0008] Furthermore, toxic gases generated by fires impose significant restrictions and difficulties on firefighters dispatched to rescue lives and suppress the fire at the point of origin.

[0009] In addition, many human casualties occur due to the generation of unexpected toxic gases during work in confined spaces such as tank trucks or underground spaces. Although hazardous gas detection devices are installed in these spaces, the effectiveness of safety improvements is insufficient, as they fail to handle hazardous gases that have already been generated.

[0010] Therefore, a method is required to effectively purify toxic gases generated at fire scenes and harmful gases generated in confined spaces such as tank trucks or underground spaces, thereby preventing casualties and enabling smooth rescue operations.

[0011]

[0012] The present invention is devised to solve the problems of the aforementioned prior art and has the purpose of measuring the air pollution level at a fire site in real time and enabling smooth air purification in real time in response to the air pollution level.

[0013] The problems of the present invention are not limited to those mentioned above, and other unmentioned problems will be clearly understood by those skilled in the art from the description below.

[0014]

[0064] Preferred embodiments of the present invention, in which the objectives of the present invention can be specifically realized, will be described below with reference to the attached drawings. In describing these embodiments, the same names and reference numerals are used for identical components, and additional explanations thereof will be omitted.

[0065] The present invention relates to an air purification device and an air purification system applicable at a fire scene that purifies air contaminated by toxic gases generated in disaster situations, particularly when a fire occurs, thereby minimizing casualties before emergency rescue.

[0066] As illustrated in FIGS. 1 and 2, the air purification device (A) according to the present invention comprises: a main body (100) having an internal space formed therein; an inlet part (200) provided in the main body (100), provided such that the internal space of the main body (100) is in communication with the outside, allowing contaminated air from the outside to flow into the interior of the main body (100); a purification part (300) provided in the internal space formed in the main body (100), purifying the contaminated air flowing into the interior of the main body (100) through the inlet part (200); a discharge part (400) provided in the upper part of the main body (100), provided such that the internal space of the main body (100) is in communication with the outside, allowing the air purified by the purification part (300) to be discharged to the outside of the main body (100); and a discharge part (400) provided in the main body (100), wherein the degree of contamination of the air outside the main body (100), that is, It may comprise an environment measuring unit (500) that senses toxic substances and toxic gases contained in the external air and photographs the external conditions to identify the ignition point of the fire or the fire scene in real time, a moving unit (600) having a plurality of wheels that can be provided at the bottom of the main body (100) to allow the main body (100) to move freely, and a control unit (700) having a communication module that controls the operation of the moving unit (600) and receives measurement information from the environment measuring unit (500) and transmits it to an administrator terminal.

[0067] At this time, the above-mentioned administrator terminal may be a controller or mobile device capable of being linked with the air purification device (A) possessed by the user of the air purification device (A), and preferably, it may be interpreted as a terminal possessed by a rescuer deployed for rescue operations at a fire scene.

[0068] The rescuer can identify information transmitted from the air purification device (A) in real time through the above-mentioned manager terminal, and by identifying in real time the on-site environment regarding where the air pollution level is high at the fire scene, the point of ignition of the fire, and the current situation of the flames, it is possible to ensure the efficient operation of the air purification device (A) as well as smooth and safe rescue activities.

[0069] According to one embodiment of the present invention, the inlet section (200), which allows contaminated air from the outside of the main body (100), i.e., the fire site, to flow into the purification section (300) provided inside the main body (100) of the air purification device (A), may be provided in a plurality of portions along the side of the main body (100). It may be formed simply as an open passage through which contaminated air from the outside can flow in, but is not limited thereto. It may be formed to include a first blower module (210) provided in the opening where the inlet section (200) is formed so that the inflow of contaminated air from the outside can be smoothly carried out.

[0070] It is preferable that the first blower module (210) above be configured to generate a flow of air in one direction from the outside to the inside of the main body (100).

[0071] Additionally, the inlet section (200) may further include a protective cover to prevent the first blower module (210) from being damaged by exposure to foreign substances such as debris from a fire scene, and such protective cover may be formed in the shape of a grid mesh or a panel having multiple perforations to prevent foreign substances from entering the first blower module (210) without obstructing the flow of air.

[0072] At this time, the first blower module (210) can control the amount of air flowing into the main body (100) by adjusting the rotational force by the control of the control unit (700) according to the pollution level of the outside air measured by the environment measuring unit (500), more specifically, the concentration of harmful substances or harmful gases contained in the outside air.

[0073] For example, if it is determined that the level of contamination of the external air of the main body (100) is high based on the information measured by the environmental measurement unit (500), the control unit (700) can increase the rotational speed of the first blower module (210) to increase the amount of contaminated air flowing into the interior of the main body (100), thereby allowing the purification of the external air to proceed quickly. Conversely, if it is determined that the level of contamination of the external air is low, the control unit (700) can lower the rotational speed of the first blower module (210) so that excessive operation of the first blower module (210) does not occur.

[0074] At this time, depending on the circumstances, for example, if it is necessary to move the air purification device (A) to another area after rapidly purifying the air in the area where the air purification device (A) is currently deployed and operating, the control unit (700) can rapidly rotate the first blower module (210) according to the control command of the administrator terminal to increase the amount of contaminated air flowing into the main body (100), thereby allowing the air purification work to be completed quickly.

[0075] According to one embodiment of the present invention, the purification unit (300) that purifies contaminated air introduced into the interior of the main body (100) through the inlet (200) into clean air may be provided in the interior space of the main body (100) and may comprise a first filter module (310) that is connected to the inlet (200) and contains a purification liquid that receives and purifies the contaminated air introduced into the main body (100), and a second filter module (320) that is provided in the interior space of the main body (100) and is positioned above the first filter module (310) to receive and filter the purified air that has passed through the first filter module (310).

[0076] In other words, the purification unit (300) may be composed of a first filter module (310), which is a liquid filter that allows harmful substances or harmful gases contained in the contaminated air to be dissolved in the purification liquid by passing the contaminated air introduced into the interior of the main body (100) through the inlet unit (200), and a second filter module (320), which is an air filter that allows the purification and filtering of the contaminated air to be fully achieved by secondarily filtering the air that has been primarily purified through the first filter module (310), and may be structured such that purification by the first filter module (310) and filtering by the second filter module (320) are performed sequentially.

[0077] At this time, the first filter module (310) may comprise a purification unit (311) in which a purification liquid is contained, a flow path unit (312) in which one side is connected to the purification unit (311) and the other side is connected to the inlet (200) so that contaminated air introduced into the interior of the main body (100) through the inlet (200) can be introduced into the purification unit (311), and a backflow prevention unit (313) provided between the purification unit (311) and the flow path unit (312) to prevent the purification liquid contained in the purification unit (311) from flowing into the flow path unit.

[0078] At this time, one side of the Euro unit (312) is configured to include and surround the inner surface of the first blower module (210) of the inlet section (200), more specifically, the inner surface of the first blower module (210) located inside the main body (100), so that contaminated air entering through the inlet section (200) can be delivered to the purification unit (311) without indiscriminate leakage.

[0079] In addition, the other side of the above-mentioned Euro unit (312) is preferably structured such that the side connected to the purification unit (311) is divided into multiple parts so that each part can be connected to one side of the purification unit (311), thereby increasing the contact area between the contaminated air and the purification liquid so that contaminated air is evenly introduced into the purification unit (311) and the contaminated air is increased, so that harmful substances and harmful gases contained in the contaminated air passing through the purification liquid can be stably dissolved in the purification liquid.

[0080] At this time, it is preferable that the divided side of the above-mentioned Euro unit (312) be connected to the lower side of the above-mentioned purification unit (311) so that contaminated air flowing into the interior of the above-mentioned purification unit (311) through the above-mentioned Euro unit (312) naturally passes through the purification liquid and rises.

[0081] In addition, the above-mentioned backflow prevention unit (313) can be provided on each of the divided sides of the above-mentioned flow unit (312) so that the purification liquid contained inside the purification unit (311) can be prevented from leaking through the above-mentioned flow unit (312) connected to the purification unit (311).

[0082] The air that is primarily purified through the first filter module (310) formed in this manner is transferred to the second filter module (320) provided on the upper part of the first filter module (310) so that secondary filtering can be performed.

[0083] To this end, the second filter module (320) may be provided on the upper portion spaced apart from the first filter module (310) at a certain distance, and may be formed by including a filter unit (321) (meaning an air filter) having an area equal to the planar area of ​​the internal space of the main body (100), and the second filter module (320) may be formed into a single cartridge structure by stacking a plurality of the filter units (321).

[0084] At this time, the filter unit (321) may consist of a pre-filter that filters large particles (ash, dust, etc.), a HEPA filter that removes ultrafine particles or smoke particles and can filter 99.97% of particles larger than 0.3 microns, an activated carbon filter that can remove toxic gases such as carbon monoxide, hydrogen chloride, and sulfuric acid, and a UV filter that can remove bacteria or viruses, and the second filter module (320) may be structured such that the filtering effect of contaminated air can be maximized by multi-stage stacking of the combination of the pre-filter, HEPA filter, activated carbon filter, and UV filter.

[0085] As illustrated in FIG. 3, the second filter module (320) may be formed as a single cartridge structure having an area equal to the planar area of ​​the internal space of the main body (100) as described above, and may be formed to have a guideline that slides into a coupling groove (120) formed on one side of the inner surface of the main body (100) so as to facilitate replacement and insertion of the second filter module (320), but is not limited thereto. It may be formed as a rotary filter carrier in the form of a rotary drum so as to have a structure into which a pre-filter, a HEPA filter, an activated carbon filter, and a UV filter are inserted. Depending on the type of harmful substance measured by the environmental measuring unit (500), a motor embedded in the rotary filter carrier is driven so that a filter suitable for the measured harmful substance is placed in the air flow path, thereby maximizing the filtering efficiency by the second filter module (320).

[0086] For example, if the external contaminated air of the main body (100) is measured to have a high amount of carbon monoxide, the control unit (700) can drive the motor built into the rotary filter carrier so that the activated carbon filter can be positioned in the air flow path, and if the amount of fine dust is measured to be high, the HEPA filter can be positioned in the air flow path in the same way.

[0087] In this way, depending on the type of harmful substances and harmful gases contained in the contaminated air, the most effective filter among the filters of the second filter module (320) can be applied, as described above, by a rotary filter carrier, but is not limited thereto, and by being formed with a sliding structure equipped with an electric slider, at least one of the pre-filter, HEPA filter, activated carbon filter, and UV filter of the second filter module (320) can be applied so that the filtering efficiency for the contaminated air can be maximized.

[0088] By being structured as described above, the purification unit (300) according to the present invention allows the contaminated air introduced into the interior of the main body (100) to be purified primarily as it passes through the first filter module (310), and the purified air that has passed through the first filter module (310) to be filtered as it passes through the second filter module (320), thereby enabling the clean air, which has been purified and filtered, to be discharged to the outside of the main body (100) through the discharge unit (400).

[0089] At this time, the purification unit (300) may be provided between the first filter module (310) and the second filter module (320), and may further include a second blower module (330) that generates an upward airflow so that the purified air passing through the first filter module (310) can be smoothly delivered to the second filter module (320). The second blower module (330) may have a rotational force controlled by the control of the control unit (700) so that the air flow from the first filter module (310) to the second filter module (320) can be unidirectional, and can be linked with the first blower module (210).

[0090] Additionally, it is preferable that the main body (100) further includes an opening / closing unit (110) formed to allow selective opening / closing on one side so as to facilitate replacement and maintenance of the first filter module (310) and the second filter module (320).

[0091] According to one embodiment of the present invention, the discharge unit (400), which allows clean air purified and filtered through the purification unit (300) inside the main body (100) to be discharged to the outside of the main body (100), may comprise a head module (410) having one side connected to the upper surface of the main body (100) and the other side formed to protrude upward from the main body (100), and having a hollow interior to serve as a flow path for the air purified and filtered by the purification unit (300) to be discharged to the outside, and a third blower module (420) which may be provided at the connection part between the head module (410) and the main body (100) to enable smooth discharge of air to the outside of the main body (100).

[0092] At this time, the third blower module (420) is capable of being linked with the first blower module (210) and the second blower module (330), and it is preferable that the rotational force be controlled by the control of the control unit (700) so that the amount of air discharged from the main body (100) can be controlled.

[0093] For example, if the rotational force of the first blower module (210) increases by the control of the control unit (700) so that the amount of contaminated air flowing into the main body (100) increases, the rotational force of the second blower module (330) can also be increased by the control of the control unit (700) so that the amount of purification of the contaminated air increases, and the rotational force of the third blower module (420) can also be increased by the control of the control unit (700) so that the amount of purified and filtered clean air discharged from the discharge unit (400) can increase.

[0094] In addition, it is desirable to position the discharge port from which purified and filtered air is discharged in the head module (410) in a different axial direction from the inlet (200) provided on the side of the main body (100), so that the mutual interference of the air flow through the inlet (200) and the discharge (400) is minimized, and the arrangement direction of the inlet (200) and the discharge (400) can be more easily understood by referring to FIG. 1.

[0095] According to one embodiment of the present invention, the environment measuring unit (500), which can measure and identify the external environment of the main body (100), that is, the pollution level of the external air and the fire situation, may be provided on the upper part of the main body (100) and may comprise a camera module (510) that photographs the external situation of the main body (100) and a sensor module (520) that may be provided on the upper part of the main body (100) and senses the pollution level of the air by detecting toxic substances (harmful gases and harmful substances) contained in the air outside the main body (100).

[0096] At this time, it is desirable that the camera module (510) be composed of a thermal imaging camera (511) and an infrared camera (512) so as to accurately identify the ignition point or flames, the direction of flame spread, and the temperature distribution at the fire scene.

[0097] In addition, the camera module (510) may further include a camera unit for capturing images in addition to the thermal imaging camera (511) and the infrared camera (512), thereby enabling visual (image or video) identification of the fire scene, in other words, visual detection of smoke or harmful substances.

[0098] In addition, the sensor module (520) is configured to include a multi-hazardous gas detection sensor that measures the concentration of hazardous gases in the air in real time, including carbon monoxide, carbon dioxide, hydrogen chloride, hydrogen sulfide, etc., and a fine dust sensor that detects ultrafine particles to measure the concentration of hazardous substances in the air, thereby enabling real-time identification of the concentration of hazardous substances and hazardous gases and the types of hazardous substances.

[0099] The above camera module (510) and sensor module (520) can be structured to face in the same direction so that they can be easily interconnected and accurate and rapid measurement of contaminated air can be achieved. The environment measurement unit (500) further includes a rotation module (530) that allows the camera module (510) and sensor module (520) to rotate 360 ​​degrees relative to the main body (100), thereby enabling the camera module (510) and sensor module (520) to quickly and accurately identify the fire scene through the rotation module (530) even if the main body (100) does not rotate.

[0100] The above-mentioned rotation module (530) can be driven by a control signal from the control unit (700).

[0101] In addition, by identifying the spread and flow of smoke generated by the fire through the connection of the camera module (510) and the sensor module (520), the direction of flow of harmful substances and harmful gases can be identified, and the control unit (700), which receives measurement information from the environment measurement unit (500), can control the operation of the moving unit (600) so that the air purification device (A) can move along the direction of flow of harmful substances and harmful gases.

[0102] In this manner, the control unit (700) receives information on the concentration of toxic substances (hazardous substances and toxic gases) detected in real time by the sensor module (520) and information on the ignition point, current fire point, and smoke flow captured by the camera module (510), and identifies the point where toxic substances are generated in real time, and controls the operation of the moving unit (600) so that the air purification device (A) can move to the identified point.

[0103] The operation of the moving unit (600) in the above-mentioned control unit (700) can be controlled by a rescuer transmitting a control command to the control unit (700) through a manager terminal so that the air purification device (A) can be moved to a desired location, but is not limited thereto. The operation of the moving unit (600) can be controlled under the judgment of the control unit (700) so that the air purification device (A) can be moved by prioritizing a location where the generation of harmful substances and harmful gases is severe and the air pollution level is high, based on information regarding the concentration and type of harmful substances and harmful gases measured by the environmental measurement unit (500), more specifically the sensor module (520), and information regarding the ignition point or flames, the direction of flame spread, temperature distribution, etc. of the fire site identified through the camera module (510) including a thermal imaging camera (511) and an infrared camera (512).

[0104] At this time, the control unit (700) may be equipped with an artificial intelligence algorithm that identifies critical points considering air pollution levels through machine learning based on information from the environment measurement unit (500), and it should be noted that such an algorithm is applied in the same way to the air purification system described later.

[0105] The air purification device (A) having the structure described above is not limited to being deployed and operated as a single unit at a fire site, and an air purification system can be formed by deploying and operating multiple units depending on the scale and fire conditions of the fire site.

[0106] Thus, the air purification system according to the present invention comprises a main body (100) having an internal space formed therein, an inlet part (200) provided in the main body (100) such that the internal space of the main body (100) is connected to the outside so that contaminated air from the outside is introduced into the interior of the main body (100), a purification part (300) provided in the interior of the main body (100) to purify the contaminated air introduced into the interior of the main body (100) through the inlet part (200), a discharge part (400) provided on the upper part of the main body (100) such that the internal space of the main body (100) is connected to the outside so that the air purified by the purification part (300) is discharged to the outside, an environment measurement part (500) provided in the main body (100) to sense the degree of contamination of the air outside the main body (100) and to photograph the external conditions, and an environment measurement part (500) provided on the lower part of the main body (100) such that the The air purification device (A) may be configured to include a movement unit (600) that allows the movement of the main body (100) to be freely performed, and a control unit (700) having a communication module that controls the operation of the movement unit (600) and receives measurement information from the environment measurement unit (500) and transmits it to an administrator terminal; an integrated control server (800) that can be linked with the control unit (700) of the air purification device (A) and receives information measured by the environment measurement unit (500) in real time and transmits control commands so that the air purification device (A) can be operated in response to the air pollution level; and a GPS module that can be provided in the air purification device (A) and transmits the location of the air purification device (A) in real time to the integrated control server (800) so that the location of the air purification device (A) can be identified by the integrated control server (800).

[0107] At this time, the air purification system is configured such that the air purification device (A) is composed of multiple units rather than a single unit as described above, so that mutual cooperation can be achieved by the control command of the integrated control server (800) in the event of a fire, and the GPS module may be configured to be included in the control unit (700) provided in each of the air purification devices (A).

[0108] Additionally, a plurality of the air purification devices (A) may be connected to the integrated control server (800) by a communication module included in the control unit (700) provided in each, and the integrated control server (800) may monitor the status of each of the air purification devices (A) and comprehensively analyze the pollution level of the external air and the location information of the air purification devices (A) based on information measured by the environment measurement unit (500) so that the operation of the air purification devices (A) may be controlled.

[0109] For example, if the fire site is large, the integrated control server (800) can divide the site area and control the distribution of multiple air purification devices (A) in each divided area. If the air pollution level measured by the environmental measurement unit (500) in one of the divided areas exceeds a standard value individually set for the air purification devices (A), the server can control the location of the multiple distributed air purification devices (A) and transmit a control command so that at least two air purification devices (A) can be operated within one area, thereby enabling efficient air purification work in real time according to the site conditions.

[0110] The above-mentioned integrated control server (800) can be directly operated by a manager of the control room controlling the fire scene to drive the air purification device (A) in response to the situation at the fire scene, but is not limited thereto. By applying an AI algorithm and a cluster control system, multiple air purification devices (A) can cooperate with each other to enable efficient air purification for the entire fire scene area through integrated control.

[0111] For example, the integrated control server (800) receives and collects information data measured by an environment measurement unit (500) equipped in each air purifier (A) in real time, and analyzes it to consider not only the surrounding environment of the area where each air purifier (A) is placed, but also the distance between each air purifier (A) or the situation of the nearby area, thereby enabling smooth cooperation of multiple air purifiers (A) for a specific area through a clustered control algorithm.

[0112] That is, if the information data measured by the environmental measurement unit (500) of an air purifier (A) placed in a certain area is analyzed and it is determined that the air pollution level of that area is very high, the integrated control server (800) can transmit a control command through a cluster control algorithm to allow another air purifier (A) placed in an area adjacent to that area to move to that area and provide support, and by placing multiple air purifiers (A) in an area with a very high air pollution level, the air purification work can be carried out efficiently and stably.

[0113] At this time, the integrated control server (800) can apply AI and machine learning algorithms to accumulate data for each fire site and, based on the accumulated data, predict the diffusion path of hazardous substances and hazardous gases that may occur in a fire situation, thereby allowing multiple air purification devices (A) to be placed in advance in the zones along the path, so that a response to the site can be made more quickly.

[0114] In addition, the integrated control server (800) can efficiently distribute the load received by the air purifier (A) placed in each zone by purifying contaminated air through an intelligent load balancing algorithm according to the air pollution level, thereby ensuring that purification work is distributed evenly among multiple air purifiers (A) and that energy consumption is minimized so that stable air purification work can be performed.

[0115] The air purification system described above can be more easily understood by referring to Fig. 5.
