Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction of smoke exhaust valves, and particularly relates to a dust reduction device for a smoke exhaust valve of an air conditioning system. Background Technique

[0002] A smoke exhaust valve is a device to prevent the spread of fire, and it is normally in an open state. In general buildings, it is usually installed at the inlet of the fan shared by the smoke exhaust system and the ventilation and air conditioning system. When a fire breaks out, the temperature of the air flow in the pipeline rises to the point where the fuse is easily melted. The core rod is then pushed by the spring, disengaging the fork plate, and the valve shaft rotates under the action of the torsion spring to close the valve. Usually, if the air volume needs to be adjusted, the opening of the valve can be adjusted through the handle linked to the valve shaft, and when the requirement is met, its position is fixed by the locknut. A closing electric signal output device can be added according to user requirements to become a smoke exhaust valve. The existing dust reduction device for the smoke exhaust valve of the air conditioning system has wet dust reduction treatment for the dust generated in the smoke exhaust valve, but it is difficult to spray and remove dust over a large area, and the sewage generated after spraying and the dust is difficult to clean up, which has limitations. In view of the above-mentioned problems, a dust reduction device for a smoke exhaust valve of an air conditioning system is proposed.

[0003] The publication number is CN218774542U, which discloses a dust reduction device for a smoke exhaust valve of an air conditioning system, belonging to the field of dust reduction devices. It includes a smoke exhaust valve body, and a dust reduction mechanism is arranged at the rear end of the smoke exhaust valve body. The dust reduction mechanism includes a dust reduction box, vertical bars, a filter frame, a dust removal filter screen, a water storage tank, a water outlet pipe, a water pump, a dust reduction pipe and a spray head. The dust reduction box is fixedly connected to the rear end of the smoke exhaust valve body, and the vertical bars are fixedly connected to both sides of the rear end of the dust reduction box. The dust removal filter screen is fixedly connected inside the filter frame, and the filter frame is fixedly connected between the symmetrical vertical bars through the clamping bars on both sides. By arranging the dust reduction mechanism at the rear end of the smoke exhaust valve body, the flue gas discharged from the smoke exhaust valve body is subjected to double filtration operations through the dust reduction mechanism, which can greatly reduce the soot content in the flue gas and improve the dust reduction treatment effect on the flue gas. Furthermore, the smoke exhaust valve body has the function of smoke exhaust and dust reduction, and it is ensured that the flue gas discharged through the smoke exhaust valve body will not cause pollution to the environment and harm to the human body.

[0004] Regarding the above-mentioned prior art, the inventor believes that there are the following deficiencies. The dust reduction device for the smoke exhaust valve of the air conditioning system conducts double filtration operations on the flue gas discharged from the smoke exhaust valve body through the dust reduction mechanism, which can greatly reduce the soot content in the flue gas and improve the dust reduction treatment effect on the flue gas. Furthermore, the smoke exhaust valve body has the function of smoke exhaust and dust reduction, and it is ensured that the flue gas discharged through the smoke exhaust valve body will not cause pollution to the environment and harm to the human body. However, the dust reduction device for the smoke exhaust valve of the air conditioning system has wet dust reduction treatment for the dust generated in the smoke exhaust valve through the dust reduction mechanism, but it is difficult to spray and remove dust over a large area, and the sewage generated after spraying and the dust is difficult to clean up, which has limitations.
