[0027] See also Figure 1 and Figure 4 As shown, a flue gas denitration and upgrading treatment device, an inlet filter assembly 5, includes a filter box 501, an inlet pipe 502, a clamping block 503, a filter screen 504, a control shaft 505, and a clamping rod 506.

[0028] See also Figure 1 and Figure 5As shown, a flue gas denitrification and upgrading treatment device, an outlet control component 6, includes an outlet pipe 601, a leakage hole 602, a threaded rod 603, a blocking block 604, and a control handle 605. The outer wall of the outlet pipe 601 is provided with a leakage hole 602, and the inner thread of the outlet pipe 601 is connected with a threaded rod 603, one end of the threaded rod 603 is fixedly connected with the blocking block 604, and the other end of the threaded rod 603 is fixedly connected with the control handle 605, the blocking block 604 forms a sliding structure with the leakage hole 602 through the threaded rod 603, and the threaded rod 603 is threadedly connected with the outlet pipe 601; it is convenient to control the discharge of flue gas, simple to operate, and easy to use.

[0029] Working principle: First, the flue gas will enter the filter box 501 from the inlet pipe 502. At this time, the flue gas will be filtered by the filter screen 504 to filter out large particles of impurities in the flue gas. If the filter screen 504 needs to be replaced or cleaned, the control shaft 505 can be rotated at this time. The control shaft 505 can rotate the clamping rod 506, so that the clamping block 503 is free from the restriction of the clamping rod 506, and the filter screen 504 can be taken out of the filter box 501 for cleaning or replacement. After cleaning or replacement, the filter screen 504 is placed in the filter box 501, and the control shaft 505 is rotated again, so that the control shaft 505 drives the clamping rod 506 to rotate at the top of the filter box 501, so that the clamping rod 506 is clamped into the clamping block 503 to prevent it from falling out. The filter screen 504 can be replaced or cleaned daily to reduce large particles of impurities entering the flue gas denitration treatment box 1, and then the filtered flue gas will enter the flue gas denitration treatment box 1.

[0030] Next, a heating tube 2 is arranged in the flue gas denitration treatment box 1, and a temperature sensor 301 is also arranged to monitor the temperature in the flue gas denitration treatment box 1 in real time. The working principle of the temperature sensor 301 is based on the thermoelectric effect or the thermal resistance effect. When the temperature changes, the resistance or electromotive force of the material will change, thereby generating an electrical signal. These signals can be further processed and converted into the output information we need. At this time, the temperature sensor 301 transmits the sensed temperature to the processor 302. When the processor 302 senses that the temperature is lower than the set temperature, it will start to transmit in the form of an electrical signal, so that the telescopic inner core 304 extends from the telescopic outer shell 303 and presses against the rotating piece 306, so that the rotating piece 306 rotates around the power supply 305 and finally touches the control power supply 307. When the rotating piece 306 touches the control power supply 307, the circuit of the heating tube 2 is connected and starts heating. Conversely, when the temperature is higher than the set temperature, the circuit will be closed at this time, so that the temperature in the flue gas denitration treatment box 1 is controlled between 850°C and 1100°C.

[0031] Finally, the reducing agent is injected into the adding pipe 401. At this time, the controllable indicating handle 405 is turned, and the control indicating handle 405 will drive the adjusting circular plate 406 to rotate, thereby opening the pipeline of the adding pipe 401. When the control indicating handle 405 is slowly turned toward the maximum position indicator 408, the amount of reducing agent injected will slowly increase. When the control indicating handle 405 is slowly turned toward the minimum position indicator 407, the amount of reducing agent injected will slowly decrease. The reducing agent will flow into the flue gas denitrification treatment box 1 through the adding pipe 401 and the shunt pipe 402, so as to quantitatively control the amount of reducing agent added. When the flue gas treatment is completed, the control handle 605 is turned at this time, and the control handle 605 will drive the threaded rod 603 to rotate, so that the blocking block 604 slides in the outlet pipe 601 until the leak hole 602 is exposed. At this time, the treated flue gas will be discharged from the leak hole 602.
