Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, and in particular to a device for detecting gas composition in ultra-high temperature environments. Background Technology

[0002] High-temperature fires may release toxic gases (such as carbon monoxide and cyanide), posing a threat to rescue personnel and the surrounding environment. Analyzing the gas composition of high-temperature fires not only helps in investigating the causes of fires and conducting safety assessments, but also optimizes firefighting strategies, assesses environmental impacts, and promotes scientific research. This information is of great significance for improving fire response efficiency, protecting life and property, and reducing environmental damage.

[0003] Existing technology discloses a coal chemical component analysis device, comprising: a shell, an analysis chamber disposed inside the shell, an air inlet pipe fixed to the side wall of the analysis chamber, a water pipe fixedly connected inside the air inlet pipe, and a condenser pipe fixedly connected inside the water pipe. Because cooling of the high-temperature gas is required to protect the internal structure, during the cooling process, water vapor in the high-temperature gas condenses into water upon cooling. This condensate absorbs gas molecules that are highly soluble in water, thus affecting the composition of the air entering the gas detector and leading to insufficient detection accuracy. Utility Model Content

[0004] The purpose of this invention is to provide an ultra-high temperature environment gas composition detection device to solve the problem in the prior art that requires cooling of high-temperature gases to protect the internal structure. However, during the cooling process, water vapor in the high-temperature gas will liquefy and turn into condensate. The condensate will absorb gas molecules that are highly soluble in water, thereby affecting the composition of the air entering the gas detector and resulting in insufficient detection accuracy.

[0005] This utility model provides an ultra-high temperature environment gas composition detection device, comprising:

[0006] The separation module includes a particle filtration unit and a gas phase separation unit, used for filtering and separating high-temperature gases.

[0007] A cooling module, which is connected to the separation module, is used to cool the gas output by the separation module, and includes a heat exchanger and a coolant tank.

[0008] The delivery module includes: a diaphragm pump, a check valve, a shut-off valve F, a shut-off valve G, and an exhaust pipe;

[0009] The detection module, which is connected to the cooling module and the conveying module respectively, includes: a level and temperature sensor, a pressure regulator, a flow meter and a gas detector installed in the coolant tank to detect the coolant level and temperature;

[0010] The control module is electrically connected to both the detection module and the conveying module, and is used to adjust the operating parameters of the detection equipment in real time based on the detection data from the detection module.

[0011] As a preferred technical solution for ultra-high temperature environment gas composition detection equipment, the coolant tank also includes: a coolant tank shell, a coolant chamber, a coolant inlet, and a coolant outlet.

[0012] As a preferred technical solution for ultra-high temperature environment gas composition detection equipment, a heat insulation layer is also provided between the outer shell of the coolant tank and the coolant chamber.

[0013] As a preferred technical solution for ultra-high temperature environment gas composition detection equipment, the separation module is configured as a cylindrical structure, and is also equipped with: a pressure sensor installed in the gas phase separation unit and an air pump installed at the air inlet of the separation module.

[0014] As a preferred technical solution for ultra-high temperature environment gas composition detection equipment, the control module is electrically connected to the pressure sensor and the regulating valve respectively, so as to adjust the opening of the regulating valve in real time according to the pressure sensor.

[0015] As a preferred technical solution for ultra-high temperature environment gas composition detection equipment, the gas phase separation unit includes: a high temperature inlet chamber, a separation membrane, and a high temperature outlet chamber.

[0016] As a preferred technical solution for ultra-high temperature environment gas composition detection equipment, the separation membrane is disposed between the high temperature inlet chamber and the high temperature outlet chamber, and the separation membrane has several top-closed, cylindrical protruding ceramic membrane columns on the high temperature outlet chamber side.

[0017] As the preferred technical solution for ultra-high temperature environment gas composition detection equipment, the insulation layer is a polyurethane insulation layer.

[0018] As a preferred technical solution for ultra-high temperature environment gas composition detection equipment, the heat exchanger is a copper heat exchanger.

[0019] The beneficial effects of this invention are as follows: This invention performs particle filtration and gas phase separation on high-temperature gas before cooling, and uses a ceramic membrane to separate water vapor from other gas components in the high-temperature gas. As a result, the air entering the heat exchanger will not generate condensate after cooling, thus preventing the absorption of water-soluble air components in the air flowing inside the heat exchanger. This ensures that the gas entering the gas detector is only different from the outside high-temperature air in terms of whether it contains water vapor, thereby increasing the accuracy of the detection results for the gas components in high-temperature air at fire scenes.

[0044] In detail, the separation module 1 is configured as a cylindrical structure, and is also equipped with: a pressure sensor 1222 installed in the gas phase separation unit and an air pump installed at the air inlet of the separation module.

[0045] In detail, the control module 5 is electrically connected to the pressure sensor and the regulating valve respectively, so as to adjust the opening of the regulating valve in real time according to the pressure sensor.

[0046] In detail, the gas phase separation unit 12 includes: a high-temperature inlet chamber 121, a separation membrane 122, and a high-temperature outlet chamber 123.

[0047] Furthermore, the separation membrane 122 is disposed between the high-temperature inlet chamber 121 and the high-temperature outlet chamber 123, and the separation membrane has several cylindrical ceramic membrane columns 1221 with closed tops on one side of the high-temperature outlet chamber.

After separation by the separation membrane 122, the moisture in the air remains in the high-temperature inlet chamber 121, while other air molecules in the high-temperature air enter the high-temperature outlet chamber 123.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
