a filter screen 51 is connected in the water suction pipe 5, and the filter screen 51 has the function of adsorbing large particulate matters; the periphery of the filter screen 51 is hermetically engaged with the water suction pipe 5 so that the filter screen 51 can be detached from the water suction pipe 5 for cleaning.
When the air bag 3 is inflated, the highest inflation point of the upper surface of the air bag 3 is lower than the height of the upper surface of the water tank 4, so that the inflated air bag 3 does not obstruct the outflow of the liquid in the water tank 4; the lowest expansion point of the lower bottom surface of the air bag 3 is higher than the height of the inner surface of the lower side pipe wall of the air suction pipe 2, so that the air suction pipe 2 is not blocked by the expansion of the air bag 3, and the air suction effect of the air suction pipe 2 is affected.
Working principle: when a fire disaster occurs, the fire disaster smoke guiding treatment device starts to work, the exhaust fan 1 pumps a large amount of smoke generated by the fire disaster in the air into the exhaust pipeline 2, after the smoke enters the exhaust pipeline 2, a large amount of heat in the smoke is transferred to the air bag 3 through the heat conducting sheet 31, the air bag 3 is heated and expanded, because the heat in the smoke just entering the exhaust pipeline 2 is higher than the heat in the smoke transmitted for a period of time in the exhaust pipeline 2, namely the temperature of the smoke close to the air inlet 21 is higher than the temperature of the smoke far from the air inlet 21, the expansion degree of the air bag 3 close to the air inlet 21 is higher than the expansion degree of the air bag 3 far from the air inlet 21, the air bag 3 is trapezoid from the direction close to the air inlet 21, the upper side pipe wall of the exhaust pipeline 2 is deformed towards the lower side pipe wall by the extrusion force of the air bag 3, the inner diameter of the exhaust pipeline 2 is reduced, and the air flow speed in the exhaust pipeline 2 is increased because the air quantity of the exhaust fan 1 is unchanged;
when the air bag 3 expands, an upward extrusion force is generated on the lower bottom surface of the upper water tank 4, the water tank 4 deforms upward when receiving the extrusion force from the air bag 3, at the moment, the volume of an inner cavity of the water tank 4 is reduced, so that after the water level in the water tank 4 is higher than the height of the water tank water outlet 41, water in the water tank 4 enters the exhaust pipeline 2 through the water tank water outlet pipe 42 to form a water curtain, and the water curtain not only can filter out large particulate matters in the smoke to prevent the large particulate matters from adhering to the exhaust fan 1 to damage the service life of the exhaust fan 1, but also can cool the smoke generated by fire and prevent the exhaust fan 1 from being burnt at a high temperature when contacting with the exhaust fan 1 due to the excessive temperature of the smoke, thereby damaging the exhaust fan 1; the inner diameter of the exhaust pipeline 2 is reduced due to the expansion of the air bag 3, the airflow flowing speed in the exhaust pipeline 2 is increased, and the smoke generated by fire can rapidly pass through the pipeline 2 to reach the water curtain, so that the contact between the high-temperature smoke and the inner wall of the exhaust pipeline 2 is reduced, and the burning injury of the high-temperature smoke to the inner wall of the exhaust pipeline 2 is prevented; in addition, as the air bag 3 expands with certain delay, a certain distance exists between the water curtain and the expanded air bag 3, so that the flow speed of the flue gas at the water curtain is lower than that at the front, and the flue gas can be sufficiently cooled and dedusted at the water curtain;
the fire smoke guiding treatment device discharges the cooled and dedusted smoke to the outside through the exhaust fan 1, so that the high temperature and the atmospheric pollution caused by large-particle smoke in the smoke generated by the fire are reduced.
The water entering the exhaust pipeline 2 stays at the bottom of the exhaust pipeline 2 after the flue gas is cleaned, is accumulated at the corners of the exhaust pipeline 2 and the air outlet pipeline 22 along the inclined angle of the exhaust pipeline 2, enters the water suction pipe 5 through the water outlet, is sucked upwards under the action of the water pump after entering the water suction pipe 5, and reenters the water tank 4 through the water inlet after most of large particles are filtered through the filter screen 51;
because the filter screen 51 and the water pumping pipe 5 are connected in a jogged way, the filter screen 51 can be detached from the water pumping pipe 5 for cleaning after use, so that the water pumping pipe 5 is prevented from being blocked due to too much large particulate matters attached to the filter screen 51.
Specific embodiment II: unlike the first embodiment, the air suction pipeline 2 is not provided with a water outlet; the water inlet arranged on the water tank 4 is connected with a waterway system in the floor through a water pipe, and the waterway system can be used for injecting water into the water tank 4 through the water pipe after receiving the water supplementing signal;
the lower bottom surface of the water tank 4 is provided with a water level detector, the water level detector detects the water level in the water tank 4, and when the water level is detected to be too low, the water level detector sends a water supplementing signal to the waterway system;
when the water level detector detects that the water level in the water tank 4 is too low and the expansion of the air bag 3 can not extrude the water in the water tank 4 in a fire disaster, the water level detector sends out a signal, the water channel system fills water into the water tank 4 at the moment, and the air bag 3 is cooled and contracted and returns due to the fact that the water temperature injected by the water channel system is lower than the temperature of the air bag 3 in the moment; when the water tank 4 is refilled with water and the water level is not higher than the height of the upper water outlet pipe 4, the exhaust fan 1 is used for exhausting air, and the fire smoke guiding treatment device performs secondary operation.

s202, smoke generated by fire contains a large amount of heat, the smoke enters an exhaust pipeline (2) and then triggers a water injection assembly to work, and the water injection assembly injects water into the exhaust pipeline (2) to form a water curtain;
s203, enabling the smoke to pass through the water curtain under the action of the suction force of the exhaust fan (1), enabling the smoke to be subjected to the cooling effect of the water curtain and filtering out most of large particulate matters carried by the smoke;
s204, filtering out most of large particulate matters and discharging cooled flue gas to the outside through an exhaust fan (1).
