DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0019] The present invention provides the following embodiments Example 1 The embodiment of the present invention provides an integrated environmental protection treatment device for flue gas desulfurization and denitrification, such as Figure 1-Figure 3 As shown, it includes a processing shell 1, the lower end of the processing shell 1 is connected to a liquid storage shell 5, an automatic liquid feeding mechanism is provided inside the liquid storage shell 5, the liquid storage shell 5 and the processing shell 1 are connected through a liquid feeding pipe 3 and a drop port 28, a processing mechanism is provided inside the processing shell 1, the processing mechanism is connected to the liquid feeding pipe 3, the end of the processing shell 1 away from the liquid feeding pipe 3 is connected to the flue gas pipe 2, and the upper end of the processing shell 1 is connected to the exhaust pipe 6.

[0020] The beneficial effects of the above technical solution are: The flue gas pipe 2 is used to transport the flue gas to be desulfurized and denitrified into the interior of the processing shell 1. The liquid storage shell 5 stores an adsorbent containing ammonia. The processing mechanism sprays the adsorbent containing ammonia into the interior of the processing shell 1 to react with SOx and NOy in the flue gas to achieve the purpose of desulfurization and denitrification. The automatic liquid feeding mechanism can automatically transport a certain amount of adsorbent containing ammonia as the flue gas to be desulfurized and denitrified is transported. There is no need to set up a feeding pump to transport the adsorbent containing ammonia, which solves the problem that the prior art uses an adsorbent containing ammonia to react with SOx and NOy to remove SOx and NOy in the flue gas at the same time, but a feeding pump needs to be set up separately and controlled to transport a certain amount of adsorbent containing ammonia, which increases the cost, adds control components, and the operation is time-consuming and labor-intensive.

[0021] Example 2 On the basis of Example 1, Figure 1-Figure 3 As shown, the processing mechanism includes a processing chamber 15 disposed inside the processing shell 1, a liquid spraying pipe 17 is disposed on the upper side of the processing chamber 15, a plurality of liquid spraying heads 18 are connected to the lower end of the liquid spraying pipe 17, and the left end of the liquid spraying pipe 17 is connected to a liquid inlet 30, which is disposed on the upper side of the left end of the processing shell 1; A liquid storage cavity 7 is provided inside the liquid storage shell 5, a material drop opening 28 is provided at the upper end of the liquid storage shell 5, the liquid storage cavity 7 is connected with the processing cavity 15 through the material drop opening 28, a liquid outlet 31 is provided at the left end of the liquid storage shell 5, the liquid outlet 31 is connected with the liquid storage cavity 7, and the liquid outlet 31 is connected with the inlet of the liquid delivery pipe 3, and the outlet of the liquid delivery pipe 3 is connected with the liquid inlet 30; A plurality of air guide plates 16 are provided at both ends of the middle and lower part of the processing chamber 15, and the plurality of air guide plates 16 are arranged at intervals and staggered. An air inlet 34 is provided at the lower side of the right end of the processing shell 1 , and the air inlet 34 is communicated with the processing chamber 15 , and the air inlet 34 is communicated with the fume pipe 2 .

[0022] The beneficial effects of the above technical solution are: The liquid storage chamber 7 is connected to the processing chamber 15 through the blanking port 28, so that the processing shell 1 and the liquid storage shell 5 are sealed and connected to avoid leakage of the flue gas after entering the processing shell 1. The flue gas pipe 2 transports the flue gas to be desulfurized and denitrified into the processing chamber 15 through the air inlet 34. The adsorbent containing ammonia enters the liquid spray pipe 17 through the liquid outlet 31 and the liquid delivery pipe 3. The adsorbent containing ammonia is atomized and sent into the processing chamber 15 through the liquid spray head 18. The atomized adsorbent containing ammonia is mixed and reacted with the flue gas to be desulfurized and denitrified in the processing chamber 15. The setting of the air guide plate 16 increases the residence time of the flue gas to be desulfurized and denitrified in the processing chamber 15, thereby improving the mixing reaction effect of the adsorbent containing ammonia and the flue gas to be desulfurized and denitrified.

[0023] Example 3 On the basis of Example 2, Figure 1-Figure 3As shown, the automatic liquid feeding mechanism includes a sliding chamber 4 connected to the upper end of the liquid storage chamber 7, the sliding chamber 4 is slidably connected to the sliding block 1, a rotating shaft 14 is rotatably provided in the sliding block 1, the rotating shaft 14 is rotatably connected to the rotating plate 12, a sliding groove 1 is provided on the lower side of the rotating plate 12, and a rotating plate 2 11 is slidably provided in the sliding groove 1, a spring telescopic rod is fixedly provided between the sliding groove 1 and the rotating plate 2 11, a contact switch 35 is provided at the left end of the sliding chamber 4, a contact block 1 is provided at the left end of the sliding block 1, the contact switch 35 and the contact block 1 are correspondingly provided, and the contact switch 35 is electrically connected to the spring telescopic rod through the controller 1; The automatic liquid delivery mechanism also includes a sliding chamber 29 connected to the lower end of the liquid storage chamber 7, the sliding chamber 29 is slidably connected to the sliding block 2, a rotating shaft 2 10 is rotatably provided in the sliding block 2, the rotating shaft 2 10 is rotatably connected to the rotating plate 2 11, a contact switch 4 13 is provided at the left end of the sliding chamber 29, a contact block 2 is provided at the left end of the sliding block 2, the contact switch 4 13 and the contact block 2 are correspondingly arranged, and the contact switch 4 13 is electrically connected to the alarm through the controller 4; A liquid inlet 32 ​​is provided on the upper left side of the liquid storage shell 5, and a liquid discharge port 8 is provided on the lower right side of the liquid storage shell 5. The liquid inlet 32 ​​is connected to the liquid storage cavity 7, and the liquid discharge port 8 is connected to the sliding cavity 9. Blocks are provided in the liquid inlet 32 ​​and the liquid discharge port 8.

[0024] The beneficial effects of the above technical solution are: The setting of the rotating plate 1 12 and the rotating plate 2 11 divides the liquid storage chamber 7 into two left and right spaces, and the left and right spaces are not connected. The space on the left is used to store the adsorbent containing ammonia. After a certain amount of flue gas is fed into the processing chamber 15, the air pressure in the processing chamber 15 increases, thereby increasing the air pressure in the right space of the liquid storage chamber 7 connected to the processing chamber 15 and the blanking port 28. When the air pressure in the right space increases, the rotating plate 12 and the rotating plate 2 11 are squeezed to move. The rotating plate 12 and the rotating plate 2 11 first move to the left. The setting of the sliding block 1 guides the movement of the rotating plate 12. The setting of the sliding block 2 guides the movement of the rotating plate 2 11. When the rotating plate 12 and the rotating plate 2 11 move, the adsorbent containing ammonia is pushed into the liquid delivery pipe 3, thereby completing the purpose of automatic liquid delivery. When the rotating plate 12 drives When the contact block 1 on the sliding block 1 contacts the contact switch 1 35, the contact switch 1 35 starts to extend and retract the spring telescopic rod through the controller 1. At this time, the rotating plate 1 and the rotating plate 2 11 can rotate. During this process, the rotating plate 2 11 slides along the sliding groove 1 until the rotating plate 2 11 drives the contact block 2 on the sliding block 2 to contact the contact switch 4 13. The contact switch 4 13 controls the alarm through the controller 4 to sound an alarm, reminding the staff that the adsorbent containing ammonia in the left space has been used up. It is necessary to open the refill port 32 in time and replenish the adsorbent containing ammonia in the left space. At the same time, open the drain port 8. During this process, as the adsorbent containing ammonia in the left space is gradually replenished, the rotating plate 1 and the rotating plate 2 11 are pushed to return to their original positions, and the waste liquid mixed with the flue gas to be desulfurized and denitrified is discharged through the drain port 8.

[0025] Example 4 On the basis of Example 1, Figure 1-Figure 3As shown, an air guide block 19 is provided at the upper end of the processing chamber 15, and guide plates 21 are provided at the inclined ends on the left and right sides of the air guide block 19 respectively, and the guide plate 21 is slidably connected to the second sliding groove 24, and the second sliding groove 24 is arranged at one end of the sliding sealing plate 23 close to the air guide block 19, and the sliding sealing plate 23 is slidably connected to the side end of the processing chamber 15, and a spring rod 22 is fixedly provided between the guide plate 21 and the second sliding groove 24, and a contact block 3 is provided at one end of the guide plate 21 close to the air guide block 19, and the contact block 3 connected to the left guide plate 21 is arranged corresponding to the contact switch 29, and the contact block 3 connected to the right guide plate 21 is arranged corresponding to the contact switch 3 25, and the contact switch 29 and the contact switch 29 are arranged corresponding to each other. Switch three 25 is respectively arranged at the inclined ends on the left and right sides of the air guide block 19, contact switch two 29 is electrically connected to the air detector 27 through controller two, the air detector 27 is connected to the air guide cavity 20 inside the air guide block 19, the lower side of the air guide cavity 20 is connected to the processing cavity 15, the upper side of the air guide cavity 20 is connected to the exhaust pipe 6 through the air outlet 33, the air outlet 33 is arranged at the upper end of the processing shell 1, the air detector 27 and contact switch three 25 are electrically connected to the drive motor through controller three, the drive motor is arranged at the front end of the processing shell 1, and the drive motor is fixedly connected to the connecting shaft, the connecting shaft passes through the front end of the processing shell 1 into the air outlet 33 and is fixedly connected to the baffle 26.

[0026] The beneficial effects of the above technical solution are: The setting of the spring rod 22 makes the guide plate 21 always contact with the side end of the air guide block 19. The setting of the guide plate 21 and the sliding sealing plate 23 separates the space formed by the upper end of the processing chamber 15 and the upper ends of the guide plate 21 and the sliding sealing plate 23 from the rest of the space of the processing chamber 15. After the flue gas in the processing chamber 15 reaches a certain amount, the flue gas pushes the guide plate 21 and the sliding sealing plate 23 to move upward until the contact block three on the left guide plate 21 contacts the contact switch two 29. The contact switch two 29 controls the air detector 27 to work through the controller two. The air detector 27 is used to detect the SOx and NOy contents of the gas in the air guide chamber 20. If the SOx and NOy contents of the gas in the air guide chamber 20 detected by the air detector 27 meet the standards, and the contact block three on the right guide plate 21 contacts the contact switch three 25, the air detector 27 and the contact switch three 25 are controlled by the controller three. The driving motor is controlled to work. The driving motor drives the baffle 26 to rotate through the connecting shaft to open the air outlet 33, so that the gas after desulfurization and denitrification is discharged through the exhaust pipe 6. The exhaust flow rate of the exhaust pipe 6 and the air intake flow rate of the flue gas pipe 2 must be kept the same. The contact block three is in contact with the contact switch three 25, which can make the air pressure in the processing chamber 15 at the target value, ensuring the normal movement of the rotating plate one 12 and the rotating plate two 11, so that the transportation of the adsorbent containing ammonia can be carried out normally. If the air pressure in the remaining space of the processing chamber 15 is small, under the elastic action of the spring rod 22, the guide plate 21 moves toward the direction of the air guide block 19, thereby moving downward along the inclined end of the air guide block 19, so that the contact block three is not in contact with the contact switch three 25. At this time, the driving motor controls the baffle 26 to re-block the air outlet 33, so that the air pressure in the processing chamber 15 reaches the target value again, ensuring the normal delivery of the liquid.

[0027] Example 5 On the basis of embodiment 1, a method for selecting the inclination angle of the rotating plate 12 in the initial state is also included, including the following steps: Step 1: Obtain the target mixing ratio of the flue gas and the treatment liquid according to the flue gas flow rate of the flue gas pipe 2 Theoretical liquid delivery flow rate of liquid delivery pipe 3; Step 2: According to the theoretical liquid delivery flow rate of the liquid delivery pipe 3 and formula (1), the inclination angle of the rotating plate 12 in the initial state is obtained; ; (1) in, is the inclination angle of the rotating plate 12 in the initial state, is the inverse tangent, is the density of the treatment fluid, is the gravitational acceleration, which is , is the height stroke of the liquid delivery pipe 3, is the ejection pressure of the ejection head 18, is the theoretical liquid delivery flow rate of the liquid delivery pipe 3, is the distance between the right end of the sliding block 1 and the right end of the liquid storage chamber 7 in the initial state, is the distance between the right end of the sliding block 2 and the liquid storage chamber 7 in the initial state, is the unit time, the value is 1s, is the height of the liquid storage chamber 7, is the length of the liquid storage chamber 7 along the front-to-back direction, It is the density of the waste liquid formed after the treatment liquid treats the flue gas.

[0028] The beneficial effects of the above technical solution are: By selecting a suitable inclination angle for the rotating plate 12, as the space on the right side of the liquid storage chamber 7 gradually becomes larger, the flue gas pressure in the liquid storage chamber 7 decreases, and when the gas flow rates of the flue gas pipe 2 and the exhaust pipe 6 remain unchanged, the driving force of the waste liquid falling into the space on the right side of the liquid storage chamber 7 on the rotating plate 12 and the rotating plate 2 11 is the same as the pressure change value of the right side space, thereby ensuring that the driving force of the rotating plate 12 and the rotating plate 2 11 always remains unchanged, ensuring that the smoke delivery flow rate of the flue gas pipe 2 and the theoretical liquid delivery flow rate of the liquid delivery pipe 3 always maintain the target ratio, thereby ensuring the desulfurization and denitrification effect of the flue gas to be desulfurized and denitrified. In this process, no manual intervention is required, which saves time and effort. Until the contact block 1 contacts the contact switch 1 35, the contact switch 1 35 controls the spring telescopic rod through the controller 1 to start to extend and retract, so that the smoke delivery flow rate of the flue gas pipe 2 and the theoretical liquid delivery flow rate of the liquid delivery pipe 3 still maintain the target ratio during the rotation of the rotating plate 12 and the rotating plate 2 11.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
