Description

Technical Field

[0001] The utility model relates to the technical field of flue gas purification, in particular to an asphalt smoke adsorption and purification device for pre-baked anode production. Background Art

[0002] The pre-baked anode is made of petroleum coke and pitch coke as aggregates and coal tar pitch as a binder, and is used as the anode material for pre-baked aluminum electrolysis cells. This carbon block has been calcined and has a stable geometric shape, so it is also called a pre-baked anode carbon block, and is habitually called a carbon anode for aluminum electrolysis. During the production and processing of pre-baked anodes, a large amount of asphalt smoke is generated, so an adsorption and purification device is needed to treat it.

[0003] For example, an asphalt smoke purification system applicable to a pre-baked anode kneading pot with a publication number of CN209271118U includes a kneading pot smoke collecting hood arranged above the kneading pot and a conveyor sealing hood arranged below the discharge port of the kneading pot, which adsorbs and treats the source of asphalt smoke generated, reduces the adhesion of asphalt smoke in the pipeline, and prevents the blockage of the pipeline;

[0004] This asphalt smoke purification system applicable to a pre-baked anode kneading pot is provided with a Venturi tube and a dust removal device to reduce the residence time of asphalt smoke in the pipeline. However, since there is no cleaning structure provided at the pipeline through which the asphalt smoke passes, although the residence time of asphalt smoke in the pipeline is short, with the passage of time, the inner wall of the pipeline will gradually accumulate asphalt sludge and cause blockage. Therefore, the use effect is not good. At the same time, only a dust collector is provided in the above to collect the dust particles in the asphalt smoke, but the harmful components in the asphalt smoke are not treated, so the purification effect is not good. In view of this, it is very necessary to design an asphalt smoke adsorption and purification device for pre-baked anode production to solve this problem. Content of the Utility Model

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions: An asphalt fume adsorption and purification device for pre-baked anode production, comprising a bottom plate, a first box body and a second box body. The first box body and the second box body are respectively fixedly connected to the left and right sides above the bottom plate.

[0014] Beneficial effects:

An air collecting hood 13 is fixedly connected to the lower left end of the gas guide pipe 12.

[0028] In this embodiment, it is further set that the purification mechanism includes a first filter layer 14, a second filter layer 15 and a third filter layer 16 arranged above the filter screen plate 6, and the outer walls of the first filter layer 14, the second filter layer 15 and the third filter layer 16 are all in contact with the inner wall of the first box body 2.

[0034] It should be noted that for the electrical structures and the like involved in this application, their models can be selected according to the needs of users, and only need to meet the usage requirements of this application. At the same time, their corresponding control circuits and the like are all existing technologies, and those skilled in the art can fully implement them, so no more details will be described.

[0035] Through those skilled in the art, the components in this case are connected in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0036] Embodiment: When this device needs to be used, the external power supply and control circuit of each electrical structure can be turned on. Then, the pitch fume generated during pre-baked anode production is discharged into the first box body 2 through the intake pipe 5. The pitch fume will first pass through the filter mesh plate 6 for preliminary filtration, and then successively pass through the first filter layer 14, the second filter layer 15, and the third filter layer 16 for filtration. In this way, the dirty oil and the like in the pitch fume will be intercepted and adhere to the filter mesh plate 6 under the action of gravity. At this time, the motor 11 is started, and the output shaft of the motor 11 drives the screw rod 9 to rotate regularly in a reciprocating manner. In this way, the screw rod 9 and the inverted V-shaped plate 7 cooperate to drive a pair of scraping plates 8 to move towards each other. Thus, the dirty oil and impurities on the filter mesh plate 6 can be scraped off by the scraping plates 8 and dropped into the third box body 4 below for collection. At the same time, the inverted V-shaped plate 7 can protect the screw rod 9 to prevent the dirty oil and impurities from dripping onto the screw rod 9, thereby ensuring the smooth movement of the scraping plates 8. In this way, blockage is avoided to the greatest extent, so the use effect is better.

[0037] After the pitch fume is filtered by the filtering structure in the first box body 2, it enters the second box body 3 through the air collecting hood 13 and the air guide pipe 12. At this time, the pump body 18 is started. The pump body 18 can suck the environmental protection agent in the second box body 3 through the first water pipe 19, then discharge it into the second water pipe 20, and finally spray it out through the spray head 21 to treat the harmful components in the pitch fume. Finally, the treated pitch fume is discharged through the exhaust pipe 23. In this way, the purification effect is better.
