Existing flue gas treatment processes can easily affect the normal treatment of flue gas if they contain large particulate impurities.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 4 As shown, this utility model discloses a flue gas treatment device for rapidly solidifying metal powder, including a flue gas treatment tower 1 for flue gas treatment. The flue gas treatment tower 1 is equipped with a spraying mechanism 2 for spraying treatment liquid inside. A gas supply mechanism 3 for supplying the flue gas to be treated is installed through the bottom of the flue gas treatment tower 1. Two sets of waste liquid collection pipes 4 for collecting waste liquid are installed through the bottom of the flue gas treatment tower 1. A large particle impurity filter mechanism 5 for filtering and blocking large particle impurities is fixedly connected to one side of the gas supply mechanism 3. The bottom of the large particle impurity filter mechanism 5 is fixedly connected to an impurity collection mechanism 6 for collecting large particle impurities.

[0020] The gas supply mechanism 3 introduces the flue gas that needs to be discharged into the flue gas treatment tower 1. The spray mechanism 2 sprays the treatment liquid into the flue gas treatment tower 1, thereby capturing and neutralizing harmful substances in the flue gas by spraying alkaline or neutral liquid, and effectively removing metal dust and acidic gases. The waste liquid after spraying can be collected in a centralized manner through the waste liquid collection pipe 4. The large particulate impurity filtration mechanism 5 installed during gas supply can filter and store large particulate impurities in the impurity collection mechanism 6 for centralized collection, thereby preventing the presence of large particulate impurities from affecting the normal treatment of flue gas.

[0021] like Figure 1 and Figure 2As shown, the gas supply mechanism 3 includes a gas supply pipe 16, a diversion channel 17 and a guide plate 18. The gas supply pipe 16 is fixedly installed at the bottom of the processing tower body 7. Multiple diversion channels 17 are opened through the gas supply pipe 16. A frustum-shaped guide plate 18 is fixedly installed at the top of the gas supply pipe 16.

[0022] The flue gas to be treated is supplied through the gas supply pipe 16, and then the flue gas can be discharged through the diversion tank 17. After that, the flue gas can be centrally treated through the flue gas treatment tower 1 and the spraying mechanism 2. The sprayed treatment liquid can fall through the frustum-shaped guide plate 18 and be centrally collected through the waste liquid collection pipe 4.

[0023] like Figure 1 and Figure 2 As shown, the flue gas treatment tower 1 includes a treatment tower body 7, an outlet pipe 8, reinforcing plates 9, and a catalyst treatment box 10. The top of the treatment tower body 7 is fixedly connected to the outlet pipe 8. Multiple sets of reinforcing plates 9 are fixedly installed on the outside of the treatment tower body 7, and two sets of catalyst treatment boxes 10 are fixedly installed inside the treatment tower body 7.

[0024] The flue gas discharged through the diversion tank 17 can move upward along the treatment tower 7, and then the flue gas can be treated by the catalyst treatment box 10. Then, the flue gas can be treated by the treatment liquid sprayed by the spraying mechanism 2. After the treatment is completed, the flue gas can be discharged through the exhaust pipe 8.

[0025] like Figure 1 and Figure 2 As shown, the spraying mechanism 2 includes a liquid supply pipe 11, a diversion valve 12, a diversion pipe 13, and spray heads 14. Two sets of reinforcing rings 15 are fixedly installed on one side of the flue gas treatment tower 1 and on the top of the catalyst treatment box 10. A diversion pipe 13 is inserted into the inside of the reinforcing ring 15. Multiple sets of spray heads 14 are fixedly connected to the bottom of the diversion pipe 13. One end of the diversion pipe 13 is fixedly connected to the liquid supply pipe 11 through the diversion valve 12.

[0026] In the process of spraying the treatment liquid, the liquid supply pipe 11 is connected to the external water pump and treatment liquid tank, and the treatment liquid is discharged through the diversion valve 12, the diversion pipe 13 and the spray head 14. This allows the treatment liquid to fully contact and react with the flue gas, thereby capturing and neutralizing harmful substances in the flue gas and effectively removing metal dust and acidic gases.

[0027] like Figures 1 to 4As shown, the large particle impurity filtration mechanism 5 includes a fixed flange 19, locking bolts 20, a processing pipe 21, a filter screen 22, a baffle 23, and positioning posts 24. The fixed flange 19 is provided on one side of the air supply pipe 16. The processing pipe 21 is connected to the fixed flange 19 by multiple sets of locking bolts 20. The baffle 23 is provided inside the processing pipe 21. Multiple sets of positioning posts 24 are slidably connected on the baffle 23. One end of the positioning post 24 is fixedly connected to the filter screen 22 that fits against the baffle 23.

[0028] When the flue gas is supplied, it first passes through the filter screen 22 to block it, thus preventing large particles of impurities from entering the interior of the treatment tower 7. The filter screen 22 is installed on the baffle 23 by the positioning column 24, making it easy to remove and replace the filter screen 22. The treatment pipe 21 used for impurity filtration is fixedly installed by the fixing flange 19 and the locking bolt 20, which also makes it easy to disassemble the treatment pipe 21.

[0029] like Figures 1 to 4 As shown, the impurity collection mechanism 6 includes a collection tube 25 and a sealing sleeve 26. The bottom of the processing tube 21 is provided with an inclined collection tube 25, and the bottom of the collection tube 25 is threadedly connected to a sealing sleeve 26 for sealing the bottom of the collection tube 25.

[0030] Large particles of impurities filtered by the filter screen 22 will fall into the inclined collection tube 25, which facilitates the collection of large particles of impurities. When the machine is stopped, the sealing sleeve 26 can be unscrewed to open the bottom of the collection tube 25, which facilitates the collection of impurities stored inside the collection tube 25.

[0031] In operation, firstly, the gas supply mechanism 3 introduces the flue gas to be discharged into the flue gas treatment tower 1. Then, the spraying mechanism 2 sprays the treatment liquid into the flue gas treatment tower 1, thereby capturing and neutralizing harmful substances in the flue gas by spraying alkaline or neutral liquids, and effectively removing metal dust and acidic gases. The waste liquid after spraying is then collected through the waste liquid collection pipe 4. Meanwhile, the large particle impurity filtration mechanism 5, installed during gas supply, filters and stores large particle impurities inside the impurity collection mechanism 6. The flue gas is collected in a central location to prevent large particulate impurities from affecting the normal treatment of the flue gas. The flue gas to be treated is supplied through the gas supply pipe 16, and then discharged through the diversion tank 17. After that, the flue gas is centrally treated by the flue gas treatment tower 1 and the spraying mechanism 2. The sprayed treatment liquid falls through the frustum-shaped guide plate 18 and is collected through the waste liquid collection pipe 4. The flue gas discharged through the diversion tank 17 can move upward along the treatment tower body 7, and then the flue gas can be treated by the catalyst treatment box 10, and then sprayed by the spraying mechanism 2. The treatment liquids work together to treat the flue gas. The treated flue gas is then discharged through the outlet pipe 8. During the spraying of the treatment liquid, the supply pipe 11 is connected to an external water pump and treatment liquid tank, discharging the treatment liquid through the diversion valve 12, diversion pipe 13, and spray head 14. This allows the treatment liquid to fully contact and react with the flue gas, thereby capturing and neutralizing harmful substances in the flue gas and effectively removing metal dust and acidic gases. When the flue gas is supplied, it first passes through the filter screen 22 to prevent large particles from entering. The filter screen 22 is installed on the baffle 23 via the positioning post 24, which makes it easy to remove and replace the filter screen 22. The treatment pipe 21 used for impurity filtration is fixedly installed by the fixing flange 19 and locking bolts 20, which also makes it easy to disassemble the treatment pipe 21. Large particles of impurities filtered by the filter screen 22 will fall into the inclined collection pipe 25, which is convenient for the centralized collection of large particles of impurities. When the machine is stopped, the sealing sleeve 26 can be unscrewed to open the bottom of the collection pipe 25, which is convenient for the centralized collection of impurities stored inside the collection pipe 25.

[0032] Finally, any aspects of this utility model not fully described herein utilize existing mature products and technologies.
