Description

Technical Field

[0001] The utility model relates to the technical field of wastewater and waste gas treatment, in particular to an environmental protection device for cooling wastewater and waste gas of a magnet sintering furnace. Background Technique

[0002] A magnet sintering furnace is a device used to sinter powder materials into magnetic materials. Its main principle is to heat the magnetic material powder to a certain temperature in a high-temperature environment to make it partially molten, and then recrystallize it through external pressure or specific atmosphere conditions to form a material with a certain shape and magnetic properties.

[0003] During the use of the magnet sintering furnace, waste gas will be discharged. After the waste gas is discharged, it needs to be cooled before filtration. Otherwise, if the temperature is too high, the filter material is easy to fail. Existing cooling is mostly through simple spraying treatment with a spray pipe, which cannot increase the contact time and area between water and waste gas, and cannot effectively improve the cooling efficiency and effect.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 、 2 As shown in Figures 3, 4, and 5, the present invention provides a technical solution: an environmental protection device for cooling waste water and waste gas in a magnet sintering furnace, including: a cooling water tower 5 for cooling waste water; a spray box 1 is placed below the cooling water tower 5, and a plurality of mutually staggered stratification boards 15 are fixedly connected inside the spray box 1. The length of the stratification board 15 is less than the length of the inner wall of the spray box 1, and the stratification boards 15 are arranged horizontally and staggered to divide the interior of the spray box 1 into an S-shaped air flow channel. A plurality of spray pipes 16 with atomizing nozzles are fixedly connected to the bottom of the stratification board 15. A vent pipe 11 is arranged inside the spray box 1, and a drive pipe 12 is rotatably arranged inside the vent pipe 11. A partition board 13 is fixedly connected obliquely to the outside of the drive pipe 12. When the drive pipe 12 drives the partition board 13 to rotate, the partition board 13 is similar to a fan blade and will act on the surrounding air. According to Bernoulli's law and the principle of centrifugal force, the fan blade will drive the surrounding air during the rotation process, forming the flow, separation, and guidance of the waste gas; a water drive part is arranged outside the spray box 1, and the water drive part includes a high-pressure water pump 8 connected to the cold water end of the cooling water tower 5 and a water wheel 10 fixedly connected to the drive pipe 12.

[0024] It should be noted that in the present utility model, the input end of the high-pressure water pump 8 is connected to the cold water outlet of the cooling water tower 5. The high-pressure water pump 8 sends cold water into the spray box 1 through the spray pipe 16 and the drive pipe 12. During this period, the high-pressure water pump 8 drives the water wheel 10 to rotate through high-pressure water, and the water wheel 10 drives the drive pipe 12 to rotate. Moreover, the output end of the high-pressure water pump 8 is connected to the drive pipe 12 through a rotary joint. The drive pipe 12 sprays water while rotating. The waste gas enters the drive pipe 12 from one side of the spray box 1. The water sprayed by the drive pipe 12 contacts the waste gas to cool and dust-remove it. Moreover, the upper water contacts the outer wall of the ventilation pipe 11, making the pipe wall temperature of the ventilation pipe 11 relatively low. The waste gas contacting the ventilation pipe 11 can also be cooled. The waste gas is discharged from one end of the ventilation pipe 11 and moves towards the top of the spray box 1. Under the action of the layered plate 15, the waste gas moves upward in an S-shaped path. During the movement process, the spray pipe 16 sprays and cools and dust-removes the waste gas, and then it is discharged along the top of the spray box 1.

[0025] Please refer to Figure 3 As shown in the figure, a recovery water tank 2 is fixedly connected to the bottom of the spray box 1, and a filter screen is arranged between the spray box 1 and the recovery water tank 2.

[0026] It should be noted that in the present utility model, the water after spraying falls outside the ventilation pipe 11 and then enters the spray box 1 through the filter screen, and then the cooling water is recovered through the drain pipe.

[0027] Please refer to Figure 3 、 4 As shown in Figures 1, 4, and 5, the drive pipe 12 is rotatably connected to the spray box 1. A T-shaped pipe 14 is fixedly connected to the outside of the drive pipe 12. Nozzles are arranged on the outside of the T-shaped pipe 14. The partition plates 13 are staggered and arranged on the outside of the drive pipe 12 for dividing the drive pipe 12 into S-shaped channels. The water driving part further includes a water storage tray 9 fixedly connected to the outside of the spray box 1. The water wheel 10 rotates and is placed in the water storage tray 9. The end of the drive pipe 12 passes through the middle of the water storage tray 9 and is installed with a rotary joint. The output end of the high-pressure water pump 8 is connected to a position deviating from the center of the water storage tray 9. The top of the water storage tray 9 is connected to the spray pipe 16 through a water pipe.

[0028] It should be noted that in the present utility model, the high-pressure water pump 8 flushes water into one side inside the water storage tray 9 through high pressure. The water pushes the water wheel 10 to rotate. The water wheel 10 drives the partition plates 13 to rotate through the drive pipe 12. The output end of the high-pressure water pump 8 is connected to the drive pipe 12 through a shunt pipe and a rotary joint, so as to realize the rotation and water spraying of the drive pipe 12. The partition plates 13 drive the air flow to move from the intake pipe 3 to the end of the ventilation pipe 11. During this period, the waste gas moves along the route separated by the partition plates 13. Moreover, the water sprayed by the nozzles on the outside of the T-shaped pipe 14 contacts the waste gas to cool the waste gas. The partition plates 13 drive the waste gas to enter above the spray box 1 from one end of the ventilation pipe 11 and move along the S-shaped route separated by the layered plate 15.

[0029] Please refer to Figure 1 As shown, an intake pipe 3 is provided at the position of the ventilation pipe 11 corresponding to the side of the spray box 1. The top of the spray box 1 is connected to a UV photocatalytic converter 6 through an exhaust pipe 4, and an activated carbon box 7 is fixedly connected to the output end of the UV photocatalytic converter 6.

[0030] It should be noted that in the present utility model, the waste gas enters the spray box 1 through the intake pipe 3 and then enters the UV photocatalytic converter 6 through the exhaust pipe 4. The UV photocatalytic converter 6 uses ultraviolet light (UV) for photocatalytic decomposition. When the gas passes through the UV photocatalytic converter, the ultraviolet light will excite the molecules in the gas, causing them to undergo chemical reactions, thereby decomposing some harmful gases. The output end of the UV photocatalytic converter 6 is connected to the activated carbon box 7. A plurality of activated carbon filters are vertically installed in the activated carbon box 7. Activated carbon has a strong adsorption capacity and can adsorb residual pollutants, odors, etc. in the gas. The gas treated by the UV photocatalytic converter is finally purified through the activated carbon box.
