Wherein, collection system 1 can gather the flue gas that gives off in the asphalt concrete to go into recovery unit 2 after handling the flue gas of gathering, utilize recovery unit 2 to add the pitch of retrieving again in asphalt concrete, thereby realized the reuse of flue gas. That is, the protection device of the embodiment of the invention not only collects volatile asphalt in asphalt concrete, but also adds the collected asphalt into the asphalt concrete, thereby realizing recycling of the recycled asphalt, protecting the body of workers from being damaged by asphalt smoke, recycling the recycled asphalt and improving the paving quality of asphalt pavements.
It should be noted that, in the embodiment of the present invention, the recycling device 2 may be configured in a funnel shape, which facilitates recycling of asphalt on the one hand and flow of recycled asphalt on the other hand. The recovery device 2 can be adjusted to an inclined installation state according to the requirement of practical application so as to facilitate the flow of the asphalt. In the embodiment of the present invention, the shape of the recovery device 2 and the installation state of the recovery device 2 are not particularly limited.
As shown in fig. 1, in some inventive embodiments, the collecting device 1 comprises: the collector 110, the chamber 120 and the fan assembly 130 are all fixed on the inner wall of the housing 3; the collector 110 is connected with the chamber 120, and the position of the fan assembly 130 is opposite to that of the collector 110; the recovery device 2 includes: a recovery chamber 20, wherein the recovery chamber 20 is fixed on the inner wall of the shell 3, and the recovery chamber 20 is hermetically connected with the device chamber 120; as shown in fig. 2, the fan assembly 130 is located at the left side of the chamber 120, and the fan assembly 130 is used for driving the flue gas to enter the chamber 120 along the collector 110 and flow out from the drainage port 201 arranged at the bottom of the recovery chamber 20; heaters 4 are arranged between the inner wall and the outer wall of the recovery chamber 20 and the device chamber 120, and the heaters 4 are electrically connected with a power supply device.
In the embodiment of the present invention, the collecting device 1 includes: the collector 110, the chamber 120 and the fan assembly 130, so that the flue gas emitted from the asphalt concrete is sucked into the collector 110 by the fan, and the collector 110 collects the flue gas emitted from the asphalt concrete into the chamber 120. Because the heater 4 is arranged between the inner wall and the outer wall of the chamber 120, the asphalt component in the flue gas is melted after contacting the inner wall of the chamber 120 and is adsorbed on the inner wall of the chamber 120. Because the recovery device 2 is provided with the recovery chamber 20, the recovery chamber 20 is connected with the inner wall of the shell 3, and the recovery chamber 20 is hermetically connected with the device chamber 120, asphalt components in the flue gas are melted and adsorbed on the inner wall of the device chamber 120, the melted asphalt flows into the recovery chamber 20 after being accumulated, the liquid asphalt is recovered by the recovery chamber 20, and the recovered asphalt is conveniently poured into asphalt concrete. Because the heater 4 is also arranged between the inner wall and the outer wall of the recovery chamber 20, the asphalt is prevented from being attached to the inner wall of the recovery chamber 20 and accumulating without flowing due to temperature reduction in the recovery process, the inner wall of the recovery chamber 20 is kept at the temperature at which the asphalt is melted, the asphalt can be effectively prevented from accumulating without flowing, namely, the fluidity of the recovered asphalt is increased, the heat preservation effect of the recovered asphalt is also realized, and the recovered asphalt can be directly led into asphalt concrete to be directly utilized without extra heating treatment. That is, in the invention, the collected flue gas is heated and precipitated, so that the asphalt in the concrete flue gas is melted and recycled, the body of a worker is protected from being damaged by the asphalt flue gas, the recycled asphalt is recycled, and the paving quality of the asphalt pavement is improved.
It should be noted that the heating temperature range of the heater 4 in the present application is required to be maintained between 90-150 ℃. When the heating temperature of the heater 4 is 110 ℃, the temperature of the recycled asphalt is consistent with that of the constructed asphalt concrete, so that the collected asphalt can directly flow into the asphalt concrete. Because the temperature of the asphalt concrete is directly related to the quality of the construction pavement, if the temperature does not reach the set temperature, the stability and the service life of the construction pavement are reduced, and the quality of the pavement is seriously influenced. Therefore, the heating temperature of the heater 4 must be higher than the temperature of the asphalt concrete of the user under construction, and in practical application, the appropriate heater 4 may be selected according to the temperature of the asphalt concrete, and in addition, the type of the heater 4 or the heating manner of the heater 4 is not particularly limited in the embodiment of the present invention.
