Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to a uniform air intake device for electromagnetic descaling. Background Art

[0002] According to the research results in recent years, the causes of haze include white smoke emitted from chimneys. The high-humidity smoke and soluble particles in the smoke condense with the lower-temperature air in the atmosphere, forming the "white smoke" phenomenon. The sinking smoke plume combines with other pollutant aerosols in the air, which will significantly increase the degree of environmental pollution near the chimney and even cause gypsum rain. How to effectively eliminate the "white smoke" produced by chimneys has become a new environmental protection indicator.

[0003] In order to meet the requirements of flue gas decolorization, electromagnetic decolorization devices are often used for treatment. The existing electromagnetic decolorization uses the atomized droplets in the electric field to move to the negative electrode wall after being charged. After the liquid film is formed, the liquid film automatically flows out from the bottom under the action of gravity, and the clean gas is discharged from the top of the device. It can purify dust and acid mist while removing moisture to meet higher environmental protection review standards.

[0004] After searching, a utility model patent with publication number CN216726588U specifically discloses a uniform air intake device for electromagnetic debleaching, including: an electromagnetic debleaching tower, a pressurization chamber, and cache tanks arranged in pairs; an air intake main pipe is arranged on the air intake end of the electromagnetic debleaching tower; the air intake main pipe is connected to the second side wall pipeline of the pressurization chamber; an air intake pipe is arranged on the first side wall of the pressurization chamber; the air intake pipe is connected to the wet flue gas inlet pipeline; the air intake end of the cache tank is connected to the wet flue gas inlet pipeline; the air outlet end of the cache tank is connected to the third and fourth side wall pipelines of the pressurization chamber. The device is achieved by adding a smoke pressurization chamber to the air intake pipe and arranging cache tanks on both sides of the smoke pressurization chamber. According to the amount of smoke generated in production, the cache tanks are filled and the smoke cache pipe is connected to the smoke pressurization chamber to adjust the amount of gas entering the electromagnetic debleaching device.

[0005] The above patent only realizes the electromagnetic de-bleaching operation of the exhaust gas through a pressurized nozzle and multiple chambers inside the nozzle. Before the exhaust gas is treated, preliminary filtration is required to filter out larger particles or dust inside the exhaust gas, thereby facilitating the electromagnetic de-bleaching operation and making the exhaust gas meet the emission standards. Although the above patent can make the exhaust gas de-bleaching more uniform, the filter device at the intake pipe is not easy to remove, resulting in a weakened effect of the filter device at the intake pipe after long-term use, thereby affecting the effect of the electromagnetic de-bleaching.

[0006] Therefore, it is necessary to invent a uniform air intake device for electromagnetic de-bleaching to solve the above problems. Utility Model Content

[0034] Refer to the instruction manual Figure 1-5 When the internal parts of the blocking mechanism 3 cooperate with each other to make the blocking plate 306 complete the blocking operation on the intake pipe 102, the sliding block 206 releases the squeeze of the reset spring 207, and the reset spring 207 resets and pushes the sliding block 206 to move. The sliding block 206 moves to the inside of the connecting shaft 305 through the arc groove on one side of the connecting shaft 305, so that the sliding block 206 releases the position fixation of the connecting block 204, and then pulls the pull ring 202. The pull ring 202 is forced to move and drive the connecting column 201 to move. The movement of the connecting column 201 drives the sealing plate 203 to move and separate from the intake pipe 102.

After the cleaning of the filter valve core 205 is completed, the filter valve core 205 is removed. The filter valve core 205 is installed into the air intake pipe 102, and then the swivel ring 302 is pressed to drive the telescopic column 301 to squeeze the telescopic spring 304 to shrink and move, and drive the connecting rod 303 to move into the connecting shaft 305, and then the swivel ring 302 is rotated to drive the telescopic column 301 to rotate. The rotation of the telescopic column 301 drives the connecting shaft 305 to rotate through the connecting rod 303, and the rotation of the connecting shaft 305 drives the blocking plate 306 to rotate. The blocking plate 306 rotates ninety degrees in the opposite direction to release the blocking operation on the air intake pipe 102. At the same time, the connecting shaft 305 rotates through the arc groove to squeeze the sliding block 206, so that the sliding block 206 squeezes the reset spring 207 to shrink and move. The sliding block 206 moves out of the connecting shaft 305 and passes through the connecting block 204, completing the position fixation of the connecting block 204, thereby completing the installation and fixing operation of the filter valve core 205 after cleaning.
