[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1-3As shown, an asphalt fume treatment device for an asphalt mixing plant includes a shell 1, a side of which is provided with a smoke inlet 14, and the smoke enters the shell 1 through the smoke inlet 14. A water storage tank 15 is provided at the bottom of the shell 1, and a second filter plate 19 is provided at the connection between the water storage tank 15 and the shell 1. Water outlets 18 are symmetrically provided on both sides of the shell 1, and a water mist head 181 is provided on the water outlet 18.

[0020] Specifically, when in use, the flue gas enters the shell 1 through the chimney 14, and then the water outlet 18 is started, so that the water mist head 181 sprays water to treat the flue gas, precipitate the particles in the flue gas, and perform dust reduction treatment. The flue gas falls on the second filter plate 19 with the water, and then the water is filtered through the second filter plate 19, so that the second filter plate 19 filters the particles on the water, and then the water falls into the water tank 15 for collection, and then the water outlet 18 is connected to the water tank 15 in the default state, so the water in the water tank 15 can be reused.

[0021] It should be noted that the second filter plate 19 is an activated carbon plate, which can adsorb harmful particles.

[0022] In the above scheme, smoke exhaust is achieved through the shell 1, and the side smoke inlet 14 is used to collect water used for cleaning. The water mist head 181 of the water outlet 18 is used to clean the particulate matter in the smoke. At the same time, water and particulate matter fall on the second filter plate 19. At the same time, the filter plate purifies the water, and the clean water falls into the water tank 15 for collection and secondary utilization. At the same time, the smoke is processed through the water outlet 18 connected to the water tank 15.

[0023] As an embodiment further provided by the present invention, according to Figure 1 , Figure 2 and Figure 3 As shown, the second filter plate 19 is provided with a plurality of second filter holes 20 arranged in an array.

[0024] Specifically, the water is filtered through the second filter hole 20 , so that the water is purified and falls into the water storage tank 15 .

[0025] As an embodiment further provided by the present invention, according to Figure 1 , Figure 2 and Figure 3 As shown, a cover body 11 is disposed on the top of the housing 1 , a placement groove 12 is formed on the cover body 11 , and a first filter plate 16 is disposed in the placement groove 12 .

[0026] Furthermore, the first filter plate 16 is provided with a plurality of first filter holes 17 arranged in an array.

[0027] Furthermore, a plurality of chamfered plates 13 arranged in an array are provided at the bottom of the cover body 11, and the chamfered plates 13 are in an inverted triangle shape.

[0028] Specifically, when the smoke floats upward after filtering, it will be filtered by the first filter plate 16 on the cover body 11, so that the smoke that has not been dusted by the water mist head 181 will be further filtered. When the smoke with water mist goes upward, it will be filtered by the first filter plate 16. At this time, the water will be retained through the chamfered plate 13 on the cover body 11 and remain in the water tank 15 for collection.

[0029] Working principle: When in use, the smoke enters the housing 1 through the smoke inlet 14, and then the water outlet 18 is started to spray water to treat the smoke, precipitate the particles in the smoke, and perform dust reduction treatment. The smoke falls on the second filter plate 19 with the water, and then the water is filtered by the second filter plate 19, so that the second filter plate 19 filters the particles on the water, and then the water falls into the water storage tank 15 for collection. Then the water outlet 18 is connected to the water storage tank 15 by default. Therefore, the water in the water tank 15 can be reused, and then when the smoke floats upward after filtering, it will be filtered by the first filter plate 16 on the cover body 11, so that the smoke without dust reduction in the water mist head 181 will be further filtered, and when the smoke with water mist goes upward, it will be filtered by the first filter plate 16. At this time, the water will be retained through the chamfered plate 13 on the cover body 11 and retained in the water tank 15 for collection, and the purified smoke will be discharged through the air outlet 111 on the cover body 11.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
