[0002] At present, when buildings are designed and constructed, smoke control is considered a key point in their design. Smoke control mainly includes two aspects: one is smoke prevention and the other is smoke exhaust. After investigation, it was found that most of the people who died in fires died from inhaling toxic and harmful gases. In order to reduce the occurrence of this phenomenon, fire smoke exhaust devices are usually designed in buildings. When a fire occurs, the fire smoke exhaust device can be opened manually or automatically to discharge the toxic and harmful gases generated in the fire, thereby reducing casualties.

[0003] The relevant Chinese patent with announcement number CN219243810U discloses an intelligent fire smoke exhaust device, including a soft connection component for connecting two fire pipes, the soft connection component includes a soft connection pipe and a connector connected to both ends of the soft connection pipe; the two fire pipes are close to each other and have a plug-in groove for inserting the connector, the inner wall of the fire pipe is provided with a connecting groove connected to the plug-in groove, and an elastic limiting component for fixing the connector is arranged in the connecting groove.

[0004] The inventor believes that when the above-mentioned fire smoke exhaust device is used, the smoke generated in the fire will be directly discharged from the building where the fire occurs through the fire pipe. However, the above-mentioned smoke exhaust device will discharge the smoke directly into the environment, which will cause greater pollution to the environment. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a smart fire smoke exhaust device includes a fire pipe 1 and a purification box 2 connected to the fire pipe 1. Four spray pipes 21 are provided at the upper end of the purification box 2. The spray pipes 21 are provided with a plurality of spray holes. When smoke is discharged from the fire pipe 1, spray water is introduced into the spray pipes 21. The spray water can be sprayed from the spray pipes 21. The spray water contacts the smoke in the fire pipe 1, and can purify the smoke, thereby reducing the problem of direct discharge of smoke into the environment and polluting the environment.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the fire-fighting pipe 1 is divided into a head end, a middle end and a tail end, wherein the head end is an end where smoke is sucked in, and the tail end is an end where smoke is discharged, and the purification box 2 is connected to the tail end of the fire-fighting pipe 1 .

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a liquid collecting pool 22 is provided at the lower end of the purification box 2, and a drainage pipe 23 is connected to the lower end of the liquid collecting pool 22. The spray water during flue gas purification can fall into the liquid collecting pool 22. The drainage pipe 23 provided at the lower end of the liquid collecting pool 22 facilitates the discharge of the spray water collected in the liquid collecting pool 22.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, a filter box 3 is provided on one side of the purification box 2, and two filter plate layers 4 are provided in the filter box 3. The upper end of the drain pipe 23 is connected to the filter box 3, and a drainage pump 31 connected to the drain pipe 23 is provided on the upper end of the filter box 3. The spray water in the drain pipe 23 can be pumped from the liquid collection tank 22 into the filter box 3 under the action of the drainage pump 31. The filter plate layer 4 arranged in the filter box 3 can filter the spray water, so that small smoke particles in the spray water can be filtered out; a liquid outlet pipe 32 is provided at the lower end of the filter box 3, and a liquid outlet pump 33 is provided at the liquid outlet pipe 32. The liquid outlet pipe 32 is far away from one end of the filter box 3 The liquid outlet pipe 32 is connected to the spray pipe 21 and can discharge the spray water filtered in the filter box 3. When the flue gas is purified, the drainage pump 31 and the liquid outlet pump 33 can be turned on to realize the circulation of the spray water, which can save water to a certain extent and reduce the cost of flue gas purification. The spray pipe 21 is also connected to a water supply pipe (not shown in the figure), through which external water can be added to the spray water purification circulation system. The lower end of the liquid collecting pool 22 is also connected to a wastewater pipe (not shown in the figure). When the spray water circulates many times and has no purification value, the sewage can be discharged through the wastewater pipe.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the filter plate layer 4 includes a coarse filter layer 41, a fine filter layer 42 and a filter cloth layer 43. The fine filter layer 42 is located between the coarse filter layer 41 and the filter cloth layer 43. The coarse filter layer 41 can filter large particles of impurities in the purified water, the fine filter layer 42 can filter small particles of impurities in the purified water, and the filter cloth layer 43 can further improve the filtering effect on the purified water and reduce impurities in the purified water.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, water retaining mechanisms 5 are provided at both ends of the purification box 2. The water retaining mechanisms 5 include a mounting rod 51 arranged on the purification box 2. An inclined water retaining sheet 52 is provided at the lower end of the mounting rod 51. A smoke exhaust gap 53 is left between adjacent water retaining sheets 52. The smoke exhaust gap 53 facilitates the passage of smoke. The water retaining sheets 52 at both ends of the purification box 2 are symmetrically arranged. The mounting rod 51 is arranged to facilitate the installation of the water retaining sheets 52. The water retaining sheets 52 are inclined. When spray water splashes onto the water retaining sheets 52, the water retaining sheets 52 can block the spray water, thereby reducing the problem of spray water flowing into the fire-fighting pipe 1, thereby reducing the problem of rusting of the fire-fighting pipe 1, and ultimately extending the service life of the fire-fighting pipe 1.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, the outside of the purification box 2 and the filter box 3 are provided with an insulation layer (not shown in the figure). In the north where the weather is relatively cold, the insulation layer can reduce the problem of spray water freezing in the purification box 2 and the filter box 3, thereby ensuring the circulation of the spray water.

[0029] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
