The present application relates to a high-temperature gas long-distance gas measuring device that detects and analyzes gas and dust components in real time at a fire site where harmful gas is generated with high-temperature heat.

Various risk factors occur at the fire site. In particular, since high-temperature harmful and combustible gases are generated at the site of a fire, it can cause various stages of damage, such as death, to firefighters or people who have entered the site. In addition, the high-temperature harmful and combustible gas may be adsorbed on worn clothes or equipment to cause secondary damage. Therefore, it is necessary to quickly and effectively evaluate the threat that may appear in the suppression field with a device capable of analyzing high-temperature harmful and combustible gases that may be exposed during fire suppression.

However, gas sensors that have been virtualized as close to the conventional field as possible are designed to measure the concentration of gas only at low temperatures. With the gas sensor alone, it is difficult to measure the components of high-temperature harmful and combustible gases generated during a fire due to the nature of the fire site.

On the other hand, products on the market as a gas measuring device using the flame ionization detection method generally consist of a filter, a moisture trap, a valve, and a gas analysis device. However, the products are generally used in a low temperature environment compared to a fire site such as a factory chimney, and have a limitation in that they are not suitable for use in real time at a high temperature fire site.

Therefore, there is a need for a sophisticated gas analyzer capable of protecting the safety of entrants including firefighters, analyzing in real time the components of high-temperature harmful and combustible gases generated during fire suppression, and revealing the exact cause of the fire.

Referring to FIG. 1 , the high-temperature gas long-distance measuring device 1000 according to an embodiment of the present application passes through the gas collection unit 200 for collecting high-temperature gas, and the gas collected from the gas collection unit 200 through the cooling unit. As a passage for transporting to the gas measurement unit 700 by using ), which is disposed between the condensate discharge unit 500, the cooling unit 400 and the gas measurement unit 700 to remove condensed water generated by cooling the high-temperature gas in (700) gas sampling connection pipe (600) that allows the gas sampling vessel to be mounted hermetically so that it can be further analyzed by other gas measuring devices; A gas measuring unit 700 that detects the gas cooled by the cooling unit 400 and measures the components, a temperature probe 800 positioned adjacent to the gas collection unit 200 and the transfer unit 300, and a temperature probe ( 800) may include a temperature display unit 820 indicating the temperature measured by the unit, and a gas pump 900 connected to the transfer unit 300 to adjust the flow rate of the transfer unit 300 .

1 to 3 , the gas collection unit 200 according to an embodiment of the present application is for collecting high-temperature gas and dust components generated at a fire site, and a suction unit 210 through which the gas is sucked. , may include a cyclone unit 220 that separates the primary foreign material contained in the gas sucked into it, and a filter unit 230 through which the gas discharged from the cyclone unit 220 separates the secondary foreign material. Here, fire refers to disasters including flames that occur not only indoors, but also in the field of life, including transportation means such as mountains, fields, roads, buildings, vehicles, ships, and airplanes, and may generally be a fire with a high temperature of 350℃ or higher.

The suction unit 210 according to an embodiment of the present application may serve to inhale the high-temperature gas and dust components to be measured. The suction unit 210 is disposed so that the gas is sucked from the bottom to the top, and a direction axis through which the gas is sucked through the suction unit 210 and a direction axis through which the gas rotates in the cyclone unit 220 . These can form a certain angle to each other. In general, due to the nature of fire, the generated gas rises from the bottom to the top. Accordingly, in order to effectively inhale the high-temperature gas, the suction unit 210 may be positioned at an appropriate height and may be disposed to face the ground.

According to another embodiment of the present application, the suction unit 210 and the cyclone unit 220 may be a swirler fan. Unlike a fire that occurs in a narrow space, if a fire occurs in a large space, the gas may not be evenly spread. That is, it may occur only in the upward direction and may not be smooth in the horizontal direction. In this case, the position of the suction part 210 is moved away from the high-temperature gas, so that the concentration of the measured gas may be sharply reduced. In this case, it will be easier to measure the gas component generated in a fire by greatly increasing the sampling flow rate using a gas pump or using a swirler fan with a wide dust absorption distribution range.

A swirler fan is a device installed to help mix fuel and oxidizer in the combustor and to stabilize the flame. In particular, the axial swirler fan imparts a swirling flow to the mixture or air or fuel supplied to the combustion chamber of the combustor, thereby causing the centrifugal force to act to form a pressure gradient in the radial direction. That is, a vortex is formed in the radial direction of the swirler fan. When this vortex becomes stronger, the vortex band formed at the bottom of the swirler gradually moves outward, and the flow introduced by this vortex blows air into the central part of the exhaust port. The collection area expands in the axial direction by pushing it up. As a result, the flame can be stabilized by creating a recirculation flow in the center of the swirling flow. Therefore, the suction unit 210 may be replaced with a swirler fan, and the swirler fan capable of filtering large particles with a diameter of 10 μm or more is replaced with the suction unit 210 and the cyclone unit 220 . can do.

In addition, according to an embodiment of the present application, the filter unit 230 may separate the secondary foreign material by passing the gas from which the primary foreign material is separated from the cyclone unit 220 . In general, in a fire scene, not only the gas to be measured, but also various particulate matter such as soot, dust, or dust, and the filter unit 230 may be disposed at the rear end of the cyclone unit 220 for more accurate gas measurement. . The filter unit 230 should be made of a material capable of passing a high-temperature gas. Therefore, it is possible to select and use a quartz filter made of SiO ₂ . Quartz can withstand a high temperature of about 500° C. or higher, and there is no external damage to acid substances, so it is suitable as a material for the filter unit 230 of the gas measuring device.

In the case of the present device, since particulate matter is secondarily filtered using the cyclone unit 220 and the filter unit 230 , it is preferable to have different sizes of filtered particles. In the case of the present gas measuring device, the cyclone unit 220 filters large particles with a diameter of 10 μm or more, and the filter unit 230 filters a material having a diameter smaller than that of the material filtered by the cyclone unit 220 . It is sufficient if possible, and the structure of the filter is not limited.

According to an embodiment of the present application, a direction axis in which gas is sucked through the suction unit 210 and a direction axis in which gas is rotated in the cyclone unit 220 may form a constant angle with each other. More specifically, it may form a right angle or an obtuse angle to each other. As described above, in the suction unit 210, the inlet is disposed downward to effectively suck the gas moving from the bottom to the top, and the cyclone unit 220 connected to the suction unit 210 moves in the direction in which the gas moves. Since it needs to be quickly moved to the gas measuring unit 700 through the transfer unit 300 , it is preferable to form a predetermined angle with the suction unit 210 . However, the angle may be changed and arranged so that the gas can optimally move depending on the height of the fire site or surrounding terrain.

1 to 4 , according to an embodiment of the present application, the gas measuring apparatus may include a transfer unit 300 . The high-temperature gas collected from the gas collecting unit 200 may serve as a gas movement path passing through the cooling unit 400 to the gas measuring unit 700 . The transfer unit 300 includes a transfer pipe 310 and a transfer tubing 320 , and one end of the transfer tube 310 is connected to the gas collection unit 200 and the other end is the firewall 240 . It may be connected to one end of the transfer tubing 320 from the rear, and the other end of the transfer tubing 320 may be connected to the gas measuring unit 700 .

The transfer pipe 310 is preferably made of iron or alloy material capable of withstanding a high temperature of 300° C. or higher, and may be a polygonal or bar-shaped tube having a cross-section. The shape of the transfer pipe 310 is not limited, and it is sufficient if it serves to transfer the collected gas. In addition, the transfer pipe 310 may be supported by the support part 242 of the firewall 240 . Accordingly, in the transfer pipe 310 , the center of the cyclone unit 220 , the center of the filter unit 230 , and the center of the transfer pipe 310 may be located on the same axis. That is, for smooth gas flow, the transfer pipe 310 may be connected in a straight line together with the cyclone unit 220 and the filter unit 230 .

The transfer tubing 320 may be configured in the shape of a tube made of a flexible material with a length of 10 meters or more. More specifically, it may have a length of 20 meters or more. More preferably, the transfer tubing 320 has a length that can be arranged enough to safely measure the components of the gas with an appropriate distance between the gas collection unit 200 and the gas measurement unit 700 close to the fire site. If it is sufficient, the length of the transfer tube 320 is not necessarily limited numerically.

The transfer tubing 320 may be formed to be connected to the gas measuring unit 700 through the cooling unit 400 . The transfer tubing 320 may be in the form of a tubing made of a non-combustible material such as PTFE or silicone material that can withstand a high temperature of 300° C. or less and is bendable, but is not necessarily limited thereto.

The firewall 240 may be disposed adjacent to the rear of the gas collection unit 200 . More specifically, it may be disposed between the gas collection unit 200 and the cooling unit 400 and adjacent to the gas collection unit. In order to accurately measure the components of the gas, it should be possible to position the gas collection unit 200 as close to the site as possible. Accordingly, the firewall 240 may serve to protect a person or a firefighter who enters a fire site where high-temperature gas is emitted. In addition, the firewall 240 may serve to block the high-temperature heat so that the high-temperature heat is not transmitted to the measuring device or the transfer unit. In the case of using a conventional drone or attaching a gas sensor of a robot, access was limited in many cases due to the nature of the site due to the high temperature gas. And these mobile devices have a limit in the weight that can be mounted. In order to overcome this conventional limitation, the gas measuring device 1000 may further include a firewall 240 .

According to an embodiment of the present application, the firewall 240 may have a flat plate shape or a bent plate shape. The firewall 240 may be located adjacent to the rear of the gas collection unit 200 and may be installed with respect to the ground. In addition, in order to improve the mobility of the firewall 240 , a wheel (not shown) capable of moving the firewall 240 by applying an external force may be disposed at the lower end of the firewall 240 .

In addition, the gas collection unit 200 and the transfer unit 300 may be mounted through the firewall 240 so that the gas collection unit 200 can be more easily located in a high temperature environment. The firewall 240 includes a support 242 for mounting the transfer unit passing through the transfer unit 300 in the longitudinal direction of the firewall 240, and a guide for allowing the support unit 242 to move vertically by sliding and reciprocating in the height direction. It may include a rail 244 , a locking protrusion (not shown) provided on the support part 242 , and a locking groove 246 positioned at regular intervals along the guide rail 244 .

The support part 242 may be mounted through the transfer part 300 . More specifically, the transfer pipe 310 constituting the transfer unit 300 may be mounted. The support part 242 may have a hole or form a surface to correspond to the shape of the periphery and the outer peripheral surface of the cross-section of the transfer pipe 310 . More specifically, the hole of the support part 242 may have a certain thickness so that the transfer pipe 310 can be supported, and the inner circumferential surface of the hole is formed to correspond to the shape of the perimeter and outer circumferential surface of the cross-section of the transfer pipe 310 . can be

The transfer pipe 310 may be mounted by fitting or inserting coupling to the support part 242 . As long as the transfer pipe 310 can be mounted, the shape or structure of the support part 242 is not limited.

The gas collection unit 200 may be positioned at a predetermined height. As described above, the suction unit 210 of the gas collection unit 200 may be disposed such that the inlet faces downward so that the high-temperature gas can be sucked from the bottom to the top. In addition, since the gas collection unit 200 and the transfer unit 300 are mounted by the support part 242 , the position of the gas collection part 200 may be changed according to the height of the support part 242 . The support part 242 may reciprocate by sliding up and down along the guide rail 244 on the central axis in the height direction of the firewall 240 . The support part 242 may have a protrusion (not shown) so that the support part 242 can slide, and the guide rail 244 may have a recess (not shown) that can be in contact with the protrusion. can However, it is sufficient if the support part 242 can slide and reciprocate along the guide rail 244 , and the shape and structure thereof are not limited.

The locking projection is provided in the support portion, and more specifically, the locking projection may be inserted into and coupled to the locking groove by pressing by applying an external force. According to another embodiment, the locking protrusion may be hinged with the support part to have a structure that can be fitted or spanned into the locking groove.

6 is a photograph taken so that a plurality of fin tubes are viewed from the front of the cooling unit of the prototype of the high-temperature gas long-distance measuring device according to an embodiment of the present application.

1, 2 and 4 to 6, the cooling unit 400 lowers the temperature of the high-temperature gas delivered through the transfer unit 300 to a temperature measurable by the gas measuring unit 700. As such, it may include a fin tube type heat exchanger 410 and a cooling fan 420 disposed to be spaced apart from the fin tube type heat exchanger 410. As shown, the fin tube type heat exchanger 410 includes a plurality of fin tubes. may include Each of the fin tubes may be disposed parallel to each other and communicate with each other. The cooling fan 420 spaced apart from the fin tube type heat exchanger 410 causes convection to lower the temperature of the gas transferred through the plurality of fin tubes.

The high-temperature gas generated at the fire site generally corresponds to a temperature of 500°C to 600°C. The high temperature gas must be cooled to about 50° C. or less to accurately measure the gas component. Therefore, in the case of gas cooling, it is preferable to further increase cooling performance by applying forced convection through the cooling fan 420 rather than responding only to natural cooling through the fin tube 410 . That is, the cooling unit 400 of the gas measuring device 1000 arranges the cooling fan 420 to be spaced apart from the fin tube type heat exchanger 410 by a certain distance, and then receives the heat exchange value through the cooling fan 420 . The cooling performance can be further improved. The cooling unit 400 may adjust the driving amount of the cooling unit 400 by a temperature detection unit to be described later. Meanwhile, the high-temperature gas may be naturally cooled to a certain extent until it is transferred to the cooling unit 400 . Considering the natural cooling and the amount of power of the device, it is sufficient if three to six fin tubes included in the fin tube type heat exchanger 410 communicate with each other and can be arranged in parallel, and the cooling fan 420 is A cooling fin having a size sufficient to cover all of the plurality of fin tubes 410 is sufficient.

Normally, the drain valve of the condensed water discharge unit 500 is closed to prevent discharge of the condensed water. When the condensed water flows into the condensed water accommodating part 550 and the pressure inside the condensed water accommodating part 550 is higher than a certain pressure, the float provided in the condensed water accommodating part 550 is lifted. The float lifts a shaft (not shown) connected to the drain valve to open the drain valve. It may be an auto drain valve type for discharging condensed water as described above, or a check valve type that is opened when the pressure of the condensate water exceeds a specific pressure according to another embodiment.

To enable this, it may be located at the rear end of the condensed water discharge unit 500 . In addition, the gas sampling connection pipe 600 may be equipped with a gas sampling bag or a canister. In addition, a separate metering pump may be mounted on the gas sampling connection pipe 600 so that a predetermined amount is sampled in the gas sampling bag or canister. The gas sampling connection pipe 600 may sample the gas delivered through the transfer unit 300 , and further precisely analyze the sampled gas later.
