[0002] The exhaust device is mainly used for extracting dust and peculiar smell in the factory area, and discharging the gas to the outside through a pipeline, so as to realize the discharge of dust and peculiar smell in the factory area. The existing exhaust device is mainly composed of a fan, an air outlet pipe and branch pipes. The fan extracts the air flow in the air outlet pipe. Therefore, the dust and peculiar smell in the factory area will enter the air outlet pipe communicated with it through the branch pipes, and be discharged to the outside by the fan communicated with the air outlet pipe well, so as to realize the discharge of peculiar smell and dust.

[0003] Although the above scheme can discharge dust and peculiar smell, there are still the following problems: dust and peculiar smell are discharged to the outside through the branch pipe well and the air outlet pipe. If the dust and peculiar smell are not treated, it is easy to cause the dust and peculiar smell discharged to the outside to pollute the outside air, thus affecting the outside air. Summary of the Utility Model

[0015] Preferably, the support plate includes a fixed frame fixedly connected to the housing and a sealing plate bolted to the fixed frame. The activated carbon is located on the fixed frame, and the air outlet holes penetrate through the fixed frame.

[0016] The beneficial effects of the present utility model: Compared with the prior art, the present utility model transmits air flow through the fan provided on the air outlet pipe. When the air flow enters the housing, the filter net filters the dust. After the dust filtering is completed, the air flow enters the activated carbon, and the activated carbon adsorbs the odor, thereby reducing the generation of odor and dust in the air flow. By filtering the air flow dust and adsorbing the odor, the situation of air pollution caused by the air flow discharged outdoors is reduced, and thus the external environment is less polluted.

[0025] For example Figures 1 to 2 , an exhaust device includes: an air outlet pipe 1, a fan 2, and a branch pipe 3. The air outlet pipe 1 is communicated with the fan 2, and there are several branch pipes 3, all of which are communicated with the air outlet pipe 1. When the fan 2 starts, dust and odors in the room will enter the air outlet pipe 1 through the branch pipe 3, and the air flow is transmitted by the air outlet pipe 1 and discharged to the outside, thereby realizing the discharge of the air flow;

[0026] The exhaust device in the present utility model further includes:

[0027] A housing 4, which is fixedly connected to the air outlet pipe 1 in a communicating manner and is mainly used for the transmission of the air flow;

[0028] A filter screen 5, which is disposed in the housing 4 and is mainly used for filtering dust in the air flow;

[0029] A support plate 6 and activated carbon 7. After the air flow dust is filtered, the air flow enters the support plate 6 opened on the side wall, and the activated carbon 7 disposed in the support plate 6 adsorbs the odor. After the odor is adsorbed, the air flow enters the fan 2 through the support plate 6 fixedly connected in the housing 4, thereby realizing the discharge of the air flow;

[0030] The spray head 8, before the air flow enters the filter net 5, the water inlet pipe communicated with the spray head 8 enters the spray head 8, so that the spray head 8 sprays water to cover the dust in the air flow, further improving the cleaning effect of the dust in the air flow;

[0031] The water outlet pipe 9 and the electromagnetic valve 10, when water enters the housing 4, the electromagnetic valve 10 fixedly connected to the water outlet pipe 9 opens, and the water in the housing 4 is discharged to the outside through the water outlet pipe 9 communicated with the housing 4, thereby realizing the discharge of water.

[0032] Specifically, since the housing 4 is fixedly connected with an inclined guide plate 11, a liquid level sensor 12 is arranged in the guide plate 11, and the liquid level sensor 12 is electrically connected to the electromagnetic valve 10, so the displacement sensor can sense the liquid level on the guide and transmit a signal to the electromagnetic valve 10, and the electromagnetic valve 10 opens, and the water is discharged to the outside through the water outlet pipe 9, thereby realizing the discharge of the guide plate 11.

[0033] Specifically, a plurality of adhesive rollers are fixedly connected on both sides of the housing 4 where the filter net 5 is located, and the dust in the air flow entering the housing 4 is adhered by the adhesive rollers, thereby reducing the generation of dust in the air flow.

[0034] Specifically, since the filter net 5 is fixedly connected with a support plate 6, the support plate 6 is snap-connected to the housing 4, and a sealing strip 15 is fixedly connected to the support plate 6. The sealing strip 15 can be attached to the housing 4. By the personnel disassembling the support plate 6 and moving it, the support plate 6 drives the filter net 5 to move outside the housing 4, which is convenient for the personnel to check the filter net 5.

[0035] Specifically, the adhesive roller two 16 is fixedly connected to the housing 4 in a staggered manner, and the dust in the air flow is adhered by the adhesive roller two 16, thereby reducing the generation of dust in the air flow.

[0036] Specifically, since the support plate 6 includes a fixed frame 17 fixedly connected to the housing 4 and a sealing plate 18 bolted to the fixed frame 17, the activated carbon 7 is located on the fixed frame 17, and the air outlet holes penetrate through the fixed frame 17. By the personnel disassembling the sealing plate 18, the activated carbon 7 can be replaced, which is convenient for the personnel to replace the activated carbon 7.

[0037] The principle of the present utility model: when the air flow enters the housing 4, the water inlet pipe transmits the air flow onto the filter net 5 for filtering, and then transmits the air flow onto the activated carbon 7. The activated carbon 7 adsorbs the odor. After the odor adsorption is completed, the air flow is discharged to the outside through the air outlet pipe 1, thereby realizing the discharge of the air flow.

[0038] The above embodiments are descriptions of the present utility model, not limitations on the present utility model. Any scheme obtained by simply changing the present utility model belongs to the protection scope of the present utility model.
