Description

Technical Field

[0001] The invention relates to the technical field of tail gas treatment, in particular to a tail gas treatment device for preparing modified asphalt. Background Art

[0002] With the development of industries such as highway construction, the application of modified asphalt is becoming more and more extensive. During the preparation process of modified asphalt, a large amount of exhaust gas will be generated. These exhaust gases contain a variety of harmful substances, such as volatile organic compounds, particulate matter, etc., which pose a serious threat to the environment and human health. Therefore, it is necessary to effectively treat the exhaust gas generated during the preparation process of modified asphalt.

[0003] In the field of exhaust gas treatment, the filter is a commonly used device, and its main function is to separate dispersed particles from gas or vapor.

[0004] In the treatment of modified asphalt tail gas, traditional filtering methods have certain limitations. For example, some devices use primary filters to intercept larger particles of impurities to preliminarily purify the tail gas. However, after long-term use, the static filter plate will be attached with impurity particles, resulting in reduced filtration efficiency and capacity. It cannot be conveniently cleaned by centrifugal force and clean water, and the material after tail gas treatment cannot be conveniently processed again.

When the fan 816 is started, the intake pipe 817 and the outlet pipe 818 can better discharge the treated exhaust. Furthermore, the return spring 91, the connecting block 92 and the rectangular cover 94 are cooperated to make the treated exhaust products be discharged into the rectangular box 93 through the discharge pipe 815. At the same time, the feed port 95 can be used to add a catalyst, such as a precious metal catalyst or a transition metal oxide catalyst, so that the harmful components in the exhaust are discharged in the catalyst. Under the action of the oxidizing agent, an oxidation reaction occurs and the oxidizing agent is converted into harmless substances, so that the pollutants after the exhaust gas treatment can be further treated. When the electric push rod 97 on the N-shaped frame 96 is started, the baffle 98 can move up and down, so that the treated product can be better output through the lower hopper 99. Further, the gas discharged from the outlet pipe 818 passes through the three-way pipe 101 so that the treated exhaust gas is discharged through the elbow 102. At the same time, in conjunction with the L-shaped frame 103 and the side block 104, when the asynchronous motor 105 is started, the output shaft 106 rotates, and the limit block 107 and the controller program control make the two sets of circular plates 108 can be periodically rotated and opened and closed alternately, so as to alternately block the gas discharged from the elbow 102, so as to cooperate with the arc block 10 The alternating impact of 10 and the deformation of the return spring 91 make the rectangular box 93 achieve a better shaking effect, so that the auxiliary component 9 can better treat the pollutants after exhaust gas treatment. At the same time, the circular filter plate 109 can further intercept particles with smaller particle size in the exhaust gas. Furthermore, when the vertical pipe 83 rotates, the rotating rod 111 is driven to rotate, thereby driving the brush block 112 to rotate, so that the soft bristles of the brush block 112 can clean the square filter plate 114 on the conical bucket 113. At the same time, the impeller 115 is rotated through the rising airflow, so that the conical bucket 113 is rotated in cooperation with the impeller 115, so that the square filter plate 114 is not easy to adhere to particles, which can further improve the exhaust gas treatment effect.
