[0007] By adopting the above technical solution, a fireproof window is installed through the test window, liquefied gas is introduced into the test kiln by the gasification furnace, the test unit ignites the liquefied gas, and a fire resistance test is performed on the fireproof window, which greatly reduces manual intervention and improves the efficiency and accuracy of the test; when the test is completed, the cooling unit sprays water on the fireproof window, and under the action of high temperature, the water is vaporized into water vapor, and the recovery unit recovers the water vapor, so that the water vapor generated during the test can be effectively recovered, thereby improving the recovery rate of the water vapor.

[0008] Optionally, the test part includes an ignition gun and a temperature sensor, and two groups of ignition guns are provided. The two groups of ignition guns are respectively arranged on both sides of the test window, and each group of ignition guns is provided with multiple ignition guns. The multiple ignition guns are arranged on the inner wall of the test kiln and are all electrically connected to an external controller; there are multiple temperature sensors, and the multiple temperature sensors are arranged in a circle along the vertical axis direction of the test kiln, and are all fixed on the inner wall of the test kiln.

[0009] By adopting the above technical solution, the gasifier introduces liquefied gas into the test kiln, the external controller controls the start of the ignition gun, the ignition gun ignites the liquefied gas, the temperature in the test kiln rises, and the fireproof window is tested. The temperature sensor monitors the temperature at different positions in the test kiln in real time, thereby easily ensuring the accuracy and reliability of the test results.

[0010] Optionally, the cooling unit includes a spray head, a spray pipe and a cooling pump, the spray head is fixed in the test kiln and located above the fireproof window; one end of the spray pipe is connected to the spray head, and the other end is connected to an external water source; the cooling pump is connected in series to the spray pipe and is electrically connected to an external controller.

[0011] By adopting the above technical solution, during the test, the external controller controls the cooling pump to start, and the water from the external water source is transported to the sprinkler head through the sprinkler pipe and evenly sprayed on the fireproof window. The timely water spraying of the sprinkler head can form a layer of water film to protect the surface of the fireproof window and reduce the direct damage to it caused by high temperature. When the test is completed, water from the external water source is transported to the sprinkler head through the sprinkler pipe and evenly sprayed on the fireproof window, which can quickly reduce the temperature of the fireproof window and prevent it from being damaged or deformed due to prolonged high temperature, thereby ensuring the continuity of the test and the integrity of the equipment.

When the test is over, the external control source controls the drainage pump to start, and the drainage pump discharges the water in the collection tank in time, realizing automatic discharge of water. This not only improves the drainage efficiency, but also reduces the need for manual operation, making the entire test process smoother and more efficient.

[0016] Optionally, it also includes a purification component, which includes a smoke exhaust pipe, an activated carbon plate and an exhaust pump, one end of the smoke exhaust pipe is connected to the test kiln, and the activated carbon plate is fixed in the smoke exhaust pipe; the exhaust pump is connected in series to the smoke exhaust pipe and is electrically connected to an external control source.

[0020] Optionally, a fireproof and heat-insulating layer is provided on the inner wall of the test kiln.

[0021] By adopting the above technical solution, the fireproof and thermal insulation layer can effectively isolate the influence of temperature changes in the external environment on the internal temperature of the test kiln, ensuring that the temperature in the test kiln can remain relatively stable during the test, thereby more accurately simulating the high temperature environment of the fire scene, and making it easier to improve the accuracy and reliability of the test results.
