DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the utility model.

[0023] As Figure 2 and Figure 3As shown, the filtering mechanism 6 includes an outer cylinder 601 connected to the lower end of the condensate pipe 4, an inner cylinder 602 fixedly installed in the outer cylinder 601, a filter screen cylinder 606 fixedly installed in the inner cylinder 602, a slag discharge port 603 formed at the bottom edge of the outer cylinder 601, a sealing end cover 605 fixedly installed at the bottom of the filter screen cylinder 606, a drain pipe 604 arranged at the middle position of the sealing end cover 605, a liquid inlet 607 formed at the upper end of the outer cylinder 601, a threaded port arranged at the bottom of the inner cylinder 602, and the sealing end cover 605 connected to the bottom of the inner cylinder 602 through the threaded port.

[0024] Specifically, the high-temperature exhaust gas is guided into the exhaust gas condenser 2 through the exhaust gas pipeline 1, and the high-temperature gas in the exhaust gas is cooled and treated so that the water vapor therein is condensed into liquid water. The water produced in this condensation process is then discharged through the condensate pipe 4. These condensed water drops to the inside of the inner cylinder 602, and as the condensed water accumulates, they are filtered by the filter screen cylinder 606 and then discharged from the system through the drain pipe 604. The filter screen cylinder 606 functions to filter out the carbon black dust in the condensed water, ensuring that the discharged water quality meets the standards. In addition, in order to facilitate maintenance and replacement, the user can easily unscrew the sealing end cover 605. When it is necessary to replace the filter screen cylinder 606, after unscrewing the sealing end cover 605, the user can quickly remove the damaged filter screen cylinder 606 and install a new filter screen cylinder 606 to ensure the continuous operation and processing efficiency of the system.

[0025] As shown in Figure 2 and Figure 4 , the slag removal mechanism 7 includes a motor 701 fixedly installed outside the outer cylinder 601 and a positioning ring seat 706 fixedly installed inside the outer cylinder 601, an output end of the motor 701 is fixedly installed with a drive shaft 702, an output end of the drive shaft 702 is fixedly installed with a pinion 703, the positioning ring seat 706 is rotatably installed with a large gear 704, a rotating sliding groove 707 is formed on the upper surface of the large gear 704, a spiral scraper 705 is fixedly installed at the bottom of the large gear 704, a through hole is formed at the upper end of the outer cylinder 601, the drive shaft 702 extends into the inside of the outer cylinder 601 through the through hole, the large gear 704 is rotatably installed on the positioning ring seat 706 through the rotating sliding groove 707, the pinion 703 is rotatably installed on one side of the large gear 704 through the drive shaft 702, and the large gear 704 and the pinion 703 are engaged together.

[0026] Specifically, when the motor 701 is started, it will start to rotate the drive shaft 702. With the rotation of the drive shaft 702, it will further drive the pinion gear 703 to start rotating. The rotating action of the pinion gear 703 will be transmitted to the gear wheel 704, so that it also starts to rotate. The rotation of the gear wheel 704 will drive the spiral scraper 705 to rotate between the inner cylinder body 602 and the filter screen cylinder 606. This rotating motion helps to effectively discharge the carbon black dust accumulated in the inner cylinder body 602, thereby avoiding the problem of clogging of the filter screen cylinder 606. The carbon black dust discharged from the inner cylinder body 602 will flow into the outer cylinder body 601, and the carbon black dust flowing into the outer cylinder body 601 will eventually be discharged from the system through the slag discharge port 603. Through this process, the effective separation of condensed water and carbon black dust is realized, ensuring that carbon black dust does not enter the circulating water pool, thereby protecting the cleanliness of the pool and the normal operation of the system.

[0027] Working principle: when in use, high-temperature tail gas enters the tail gas condenser 2 through the tail gas pipeline 1 and is condensed, and the condensed water is discharged through the condensed water pipe 4 and drips into the inner cylinder body 602. The condensed water in the inner cylinder body 602 eventually passes through the filter screen cylinder 606 and is discharged from the drain pipe 604, thereby filtering out the carbon black dust in the condensed water, and the user can unscrew the sealing end cover 605, and after unscrewing the sealing end cover 605, the damaged filter screen cylinder 606 can be quickly removed and replaced. When there is a lot of carbon black dust accumulated in the inner cylinder body 602, the motor 701 can be started, which will drive the drive shaft 702 to rotate, and after the drive shaft 702 rotates, it will drive the pinion gear 703 to rotate, and after the pinion gear 703 rotates, it will drive the gear wheel 704 to rotate, and after the gear wheel 704 rotates, it will drive the spiral scraper 705 to rotate between the inner cylinder body 602 and the filter screen cylinder 606, thereby discharging the carbon black dust accumulated in the inner cylinder body 602 and preventing the filter screen cylinder 606 from being clogged. The carbon black dust discharged from the inner cylinder body 602 will overflow into the outer cylinder body 601, and the carbon black dust overflowing into the outer cylinder body 601 will eventually be discharged through the slag discharge port 603, realizing the separation of condensed water and carbon black dust and preventing carbon black dust from entering the circulating water pool.
