Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting facilities, and more specifically, to an energy-saving centrifugal fire-fighting smoke exhaust fan. Background Art

[0002] Centrifugal fire smoke exhaust fan is a fan used in fire smoke exhaust system. It is widely used in commercial buildings, industrial plants, public places and other places where smoke exhaust is required. When a fire occurs, the high-speed rotating impeller sucks the smoke into the smoke exhaust fan, and then the impeller rotates to exhaust the smoke from the smoke exhaust fan, and then the smoke is discharged to the outside through the smoke exhaust duct connected to the air outlet of the smoke exhaust fan. It can quickly remove toxic smoke and harmful gases in the building, reduce the degree of indoor air pollution, provide strong support for personnel evacuation and fire fighting, and ensure the safety of life and property of personnel;

[0003] However, due to the thermal decomposition and combustion of building materials, a large number of tiny solid particulate matter will be generated and mixed in the smoke. For example, the combustion of materials such as wood, plastic, and rubber will produce a large amount of smoke and harmful particulate matter. In addition, the dust, particles and other impurities inside the building will also be carried up by the hot air flow and mixed into the smoke generated by the fire. During the smoke exhaust process, the traditional centrifugal fire smoke exhaust fan cannot process the particulate impurities entering the fan, avoid a large amount of particulate impurities entering the fan and affecting the use effect of the fan, and reduce the number of particulate impurities in the gas discharged to the outside, thereby reducing the pollution to the outdoor air, being environmentally friendly and energy-saving. At the same time, it cannot cool down the high-temperature smoke entering the fan, avoid damage to the fan caused by excessive heat in the fan, and improve practicality. Utility Model Content

DETAILED DESCRIPTION

[0016] Reference Figures 1 to 3 The utility model is further described in detail.

[0017] An energy-saving centrifugal fire smoke exhaust fan comprises a mounting frame 1 and a fan body 2 mounted on the mounting frame 1, the fan body 2 comprises a casing 3, an impeller 4 mounted in the casing 3, and an air inlet 5 and an air outlet 6 arranged on the casing 3, a smoke exhaust pipe 7 connected to the air outlet 6 for exhausting gas in the casing 3 is installed on the casing 3,

[0018] The housing 3 is provided with a treatment box 8 and a water tank 9. The water tank 9 is provided with an absorption liquid 10 for treating flue gas and a filter screen 11 placed above the absorption liquid 10. A clamping plate 12 is installed on both sides of the filter screen 11. An L-shaped plate 13 connected by two clamping plates 12 is installed on the water tank 9. The filter screen 11 is V-shaped.

[0019] A nozzle 14 and a water pump 15 are installed in the treatment box 8. A water pipe 16 corresponding to the filter 11, a liquid outlet pipe 17 connected to the nozzle 14, and a guide pipe 18 cooperating with the air inlet 5 are installed on the treatment box 8. The water pipe 16 is connected to the water pump 15. A valve is installed on the liquid outlet pipe 17 and is connected to the water tank 9. Both ends of the guide pipe 18 are connected to the air inlet 5 and the treatment box 8 respectively. A drainage pipe 19 is connected to the treatment box 8. A filter plate 20 is arranged in the drainage pipe 19. A magnet ring 21 surrounding the filter plate 20 is installed on the filter plate 20. The drainage pipe 19 is made of metal material that is magnetically connected to the magnet ring 21.

[0020] Working principle: During the smoke exhaust process, the fan body 2 works to rotate the impeller 4 in the casing 3 to generate suction to suck the smoke into the treatment box 8 through the drainage pipe 19. The filter 20 in the drainage pipe 19 performs preliminary filtration on the particulate impurities in the smoke to reduce the number of particulate impurities in the smoke entering the treatment box 8, thereby reducing the number of particulate impurities entering the fan body 2. The filter 20 is magnetically connected to the drainage pipe 19 through the magnet ring 21 to facilitate the removal and installation of the filter 20 and the drainage pipe 19. When there are too many particulate impurities on the filter 20, the filter 20 can be removed for cleaning to facilitate subsequent use. When the smoke enters the treatment box 8, the valve on the liquid outlet pipe 17 is opened to allow the absorption liquid 10 in the water tank 9 to enter the nozzle 14 through the liquid outlet pipe 17. Thus, the nozzle 14 sprays the absorption liquid 10 into the treatment box 8 to cool the incoming flue gas, thereby preventing the fan body 2 from being damaged by excessive heat in the fan body 2 due to the inhaled flue gas being too hot when the fan body 2 is exhausting smoke. At the same time, the absorption liquid 10 sprayed by the nozzle 14 settles the particulate impurities in the flue gas to reduce the number of particulate impurities in the flue gas and absorbs the harmful gases in the flue gas to reduce the pollution of the gas discharged from the fan body 2 to the air, thereby further reducing the number of particulate impurities entering the fan body 2, preventing a large amount of particulate impurities from entering the fan body 2 and affecting the use effect of the fan body 2, reducing the number of particulate impurities in the gas discharged to the outside through the smoke exhaust pipe 7, reducing the pollution to the outdoor air, and being environmentally friendly and energy-saving, and improving practicality;

[0021] After the absorption liquid 10 settles the particulate impurities in the flue gas, the water pump 15 works to pump the water 15 with the particulate impurities into the water pipe 16, and the water falls into the filter screen 11 in the water tank 9 through the water pipe 16 to filter out the particulate impurities in the absorption liquid 10, which is convenient for the recycling of the absorption liquid 10, further achieving the effect of environmental protection and energy saving, and high practicality. The filter screen 11 is V-shaped, which is convenient for the particulate impurities filtered out by the filter screen 11 to accumulate on both sides of the filter screen 11, reducing the impact on the filtering effect of the filter screen 11, and cooperating with the clamping plate 12 on the filter screen 11 and the L-shaped plate 13 on the water tank 9, so that the filter screen 11 can be removed from the water tank 9 to clean the particulate impurities filtered on the filter screen 11 for subsequent continued use, thereby further improving practicality.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
