[0030] Embodiments of the utility model provide a kind of asphalt production smoke treatment device, as shown in Figures 1-5 The asphalt production smoke treatment device includes:
[0031] The treatment chamber 100 is provided with a spraying area 101 and a collection area 102 inside, the treatment chamber 100 is provided with an air inlet 110 and an air outlet 130, the spraying area 101 is communicated with the air inlet 110, and the collection area 102 is communicated with the air outlet 130;
[0032] The electric tar precipitator assembly 200 is arranged obliquely inside the treatment chamber 100, and the spray area 101 and the collection area 102 are communicated through the electric tar precipitator assembly 200. The electric tar precipitator assembly 200 itself divides the inside of the treatment chamber 100 into the spray area 101 and the collection area 102. Under the blocking effect of the electric tar precipitator assembly 200, the flue gas needs to pass through the flow channel inside the electric tar precipitator assembly 200 from the spray area 101 to the collection area 102. During the passing of the flue gas through the flow channel of the electric tar precipitator assembly 200, the tar in the flue gas is captured by the electric tar precipitator assembly 200. The tar will be charged and precipitated under the electric field environment, so as to reduce the content of impurities such as tar mist in the flue gas. Here, the electric tar precipitator assembly 200 is arranged obliquely, and the collection unit 300 at the end of the flow channel of the electric tar precipitator assembly 200 collects the liquid precipitated and sliding in the flow channel.
[0033] The collection unit 300 is arranged on the inner wall of the spray area 101 away from the air inlet 110. One end of the electric tar precipitator assembly 200 is located above the collection unit 300.
[0034] The flue gas to be treated enters the spray area 101 from the air inlet 110, is sprayed and adsorbed by the spray pipe 400 arranged in the spray area 101, and then reaches the collection area 102 along the flow channel of the electric tar precipitator assembly 200 and leaves from the air outlet 130. During the passing of the flue gas through the flow channel of the electric tar precipitator assembly 200, the tar in the flue gas is captured by the electric tar precipitator assembly 200. The tar will be charged and precipitated under the electric field environment, so as to reduce the content of impurities such as tar mist in the flue gas. Here, the electric tar precipitator assembly 200 is arranged obliquely, and the collection unit 300 at the end of the flow channel of the electric tar precipitator assembly 200 collects the liquid precipitated and sliding in the flow channel.
[0035] In the present application, the spray area 101 and the collection area 102 are designed synchronously inside the treatment chamber 100, the collection unit 300 is constructed by using the oblique arrangement of the electric tar precipitator assembly 200, and the precipitated impurities in the electric tar precipitator assembly 200 are prevented from directly entering the circulating liquid to affect the spraying and adsorption effect. Through the structural improvement, the spraying and the electric tar capture are organically combined, the purification treatment needs are met, and the overall land occupation of the equipment is reduced.
[0036] As a preferred embodiment in the present embodiment, the electric tar precipitator assembly 200 comprises a shell, an electric tar precipitator arranged inside the shell, and a first end plate 201 and a second end plate 202 arranged on both sides of the shell. The shell is connected with the support end block arranged inside the treatment chamber 100 through the first end plate 201 and the second end plate 202. The flow channel of the electric tar precipitator is arranged obliquely to the ground.
[0037] In the present embodiment, the electric tar precipitator is the same as the prior art in principle and structure, except that the electric tar precipitator is arranged obliquely. The electric tar precipitator is connected with the inner wall of the treatment chamber 100 through the first end plate 201 and the second end plate 202. The first end plate 201 and the second end plate 202 form a certain gap between the electric tar precipitator and the inner wall of the treatment chamber 100, which facilitates the flue gas flow.
[0038] As a preferred embodiment in the present embodiment, the collecting unit 300 comprises a baffle 310, a guide plate 320 and a collecting plate 330, which are sequentially connected,
[0039] The collecting plate 330 is arranged parallel to the ground and is connected with the inner wall of the processing chamber 100 at both ends, and the baffle 310 is arranged vertically to the ground and is connected with the inner wall of the processing chamber 100 at both ends.
[0040] In further preferred embodiments of the present application, a liquid outlet conduit 140 is arranged below the collecting plate 330, and the tar collected in the collecting groove is discharged outwardly from the liquid outlet conduit 140. In addition, a cleaning port 120 is arranged on the side wall of the processing chamber 100, and a cover plate 150 is arranged at the cleaning port 120, and the collecting groove is connected with the outside through the cleaning port 120.
[0041] In the present embodiment, the cover plate 150 at the cleaning port 120 can be removed, and when the interior of the collecting unit 300 needs to be cleaned due to liquid accumulation, the cover plate 150 can be removed from the cleaning port 120 for maintenance.
[0042] As a preferred embodiment in the present embodiment, the processing chamber 100 further comprises a circulating liquid outlet, which is arranged in the spraying area 101, and the spraying liquid in the spraying process is sent out from the circulating liquid outlet and is sent back to the spraying pipe 400 by the circulating pump.
[0043] In the present embodiment, the number of the spraying pipes 400 is several groups, and the air inlet 110 is arranged on the side far away from the collecting unit 300 due to the large internal space of the spraying area 101, so that the flue gas needs to pass through a longer distance to reach the gap between the collecting unit 300 and the electric tar precipitator assembly 200, thereby prolonging the spraying contact time.
[0044] It should be noted that, for the foregoing embodiments, in order to simply describe, they are all expressed as a series of action combinations, but those skilled in the art should know that the present application is not limited by the described action sequence, because according to the present application, certain steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should know that the embodiments described in the specification all belong to preferred embodiments, and the actions and modules involved are not necessarily necessary for the present application.

Obviously, the described examples are only some of the embodiments of the present application, not all the embodiments. Based on these examples, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.
