[0041] See also Figure 1-Figure 4 .

[0042] The present invention discloses a desulfurization and denitrification waste gas treatment device, comprising a reaction chamber and a filter chamber, wherein the reaction chamber is used for providing waste liquid and reactants for flocculation reaction, the filter chamber is connected to the reaction chamber, and the waste liquid after flocculation reaction in the reaction chamber enters the filter chamber for filtration to filter out flocculants produced by the flocculation reaction.

[0043] In some embodiments, the filter chamber includes a first chamber body 5, a filter screen 9 and a pressure plate 8.

[0044] The first bin body 5 is connected to the reaction bin, and the first bin body 5 has a liquid discharge port 12 and a slag discharge port 13;

[0045] The filter screen 9 is installed in the first bin body 5, and is used to filter out the flocculants in the waste liquid. The filtered waste liquid is discharged through the liquid discharge port 12, and the filtered flocculants are discharged through the slag discharge port 13. Figure 1 As shown, the slag discharge port 13 is located above the lower end of the filter screen 9, and the liquid discharge port 12 is located at the bottom of the first bin body 5. A valve is provided on the liquid discharge port 12, which is opened when needed to discharge the filtered waste liquid;

[0046] The pressing plate 8 is installed in the first warehouse body 5 and is located above the filter screen 9. The pressing plate 8 is located between the liquid inlet of the first warehouse body 5 and the filter screen 9. A channel 15 for the waste liquid to pass through is opened on the pressing plate 8 to ensure that the waste liquid can pass through the filter screen 9. The pressing plate 8 is connected to the first driving component, and the first driving component drives the pressing plate 8 to move downward to squeeze the waste liquid above the filter screen 9 and speed up the speed of the waste liquid passing through the filter screen 9.

[0047] The desulfurization and denitrification waste gas treatment device disclosed in this scheme is provided with a pressing plate 8 in the filter chamber for squeezing the waste liquid on the filter screen 9 to accelerate the speed of the waste liquid flowing through the filter screen 9 and improve the filtering efficiency of the filter screen 9.

[0048] After the filter chamber has worked for a period of time, it is necessary to clean the floccules on the filter screen through the slag discharge port 13 so that the filter screen 9 can always maintain a good filtering state.

[0049] In some embodiments, the first driving assembly includes a first motor 6 and a lead screw 7, wherein the first motor 6 is connected to the lead screw 7, and the lead screw 7 is threadedly connected to the pressing plate 8. When working, the first motor 6 drives the lead screw 7 to rotate, so that the pressing plate 8 moves upward or downward along the axis direction of the lead screw 7.

[0050] The pressing plate 8 repeatedly moves up and down under the action of the first driving assembly, and repeatedly squeezes the waste liquid on the filter screen 9, thereby improving the filtering effect of the filter screen 9.

[0051] In some embodiments, the first driving component is a telescopic cylinder, which drives the pressing plate 8 to move up and down to repeatedly squeeze the waste liquid on the filter screen 9.

[0052] Under the action of the first driving assembly, the pressure plate 8 passively squeezes the waste liquid on the filter screen 9 . The pressure plate 8 can continuously and stably apply a pressing force to the waste liquid, thereby reducing damage to the filter screen 9 .

[0053] The first driving assembly is not limited to the above-mentioned embodiment, and may also be other first driving assemblies capable of driving the pressing plate 8 to move linearly up and down, which is not specifically limited here.

[0054] In an embodiment in which the driving assembly includes a first motor 6 and a lead screw 7, the filter chamber also includes a brush 10 fixedly connected to the lead screw 7. The lead screw 7 rotates, driving the brush 10 to rotate synchronously. The lower surface of the brush 10 is parallel to the filter screen 9, so that the brush 10 cleans the flocs at the higher end of the filter screen 9. The cleaned flocs gather at the lower end of the filter screen 9, making it easier for the flocs to be discharged through the slag discharge port 13.

[0055] In the embodiments where the first driving assembly has other structural forms, the brush 10 is driven to rotate by a separate driving member.

[0056] Preferably, the shape of the pressing plate 8 is the same as the shape of the inner wall of the first chamber body 5, so as to increase the contact area between the pressing plate 8 and the waste liquid on the filter screen 9 and improve the effect of a single squeeze.

[0057] After the pressing plate 8 moves upward, the distance between the pressing plate 8 and the filter screen 9 increases, and the waste liquid is replenished between the pressing plate 8 and the filter screen 9 through the channel 15. The pressing plate 8 squeezes the squeezed waste liquid and the replenished waste liquid at the same time, realizing continuous squeezing of the waste liquid.

[0058] Optionally, the pressing plate 8 and the first chamber body 5 are clearance-matched to prevent negative pressure from being generated between the pressing plate 8 and the filter screen 9 during the up and down movement of the pressing plate 8 .

[0059] In some embodiments, the channel 15 is opened at the end of the pressure plate 8 corresponding to the higher height of the filter screen 9, so that the waste liquid flows along the first bin body 5 of the first bin body 5, reducing the impact of the waste liquid on the filter screen 9 and protecting the filter screen 9.

[0060] The number of channels 15 provided on the pressing plate 8 may be one or more. In the embodiment where one channel 15 is provided on the pressing plate 8, the flow area of ​​the single channel 15 may be appropriately increased; in the embodiment where multiple channels 15 are provided on the pressing plate 8, the flow area of ​​the single channel 15 may be relatively reduced, and the flow areas of the multiple channels 15 may be the same or different.

[0061] In some embodiments, the channel 15 may be uniformly or non-uniformly opened along the circumference of the pressure plate 8; the cross-sectional shape of the channel 15 may be circular or may be other shapes.

[0062] The pressing plate 8 has an upper surface and a lower surface. The waste liquid in the reaction chamber falls on the upper surface, and the upper surface is used to buffer the falling of the waste liquid. The lower surface of the pressing plate 8 is opposite to the filter screen 9 and is used to squeeze the waste liquid.

[0063] In some embodiments, the upper surface of the pressing plate 8 is a first inclined surface, which is inclined toward the direction of the channel 15 to guide the falling of the waste liquid and prevent the formation of liquid accumulation on the upper surface of the pressing plate 8.

[0064] In the embodiment where there is only one channel 15 , the upper surface of the pressing plate 8 is inclined toward the channel 15 as a whole;

[0065] In the embodiment where there are multiple channels 15 and the channels 15 are concentrated on one side of the pressing plate 8, the upper surface of the pressing plate 8 is tilted as a whole toward the side of the pressing plate 8 where the multiple channels 15 are arranged;

[0066] In the embodiment where there are multiple channels 15 and the channels 15 are dispersedly arranged in the circumferential direction of the pressing plate 8 , the upper surface of the pressing plate 8 is a conical surface.

[0067] The upper surface of the pressing plate 8 mainly plays a guiding role for the waste liquid.

[0068] The lower surface of the pressing plate 8 is a second inclined surface, which is parallel to the filter screen 9 to ensure that when the pressing plate 8 is pressed down, the pressure applied by the pressing plate 8 to each part of the filter screen 9 is equal, which can not only optimize the filtering effect of the waste liquid, but also protect the filter screen.

[0069] In some embodiments, the pressing plate 8 includes an upper plate 81 and a lower plate 82, wherein the upper plate 81 is an elastic plate and the lower plate 82 is a rigid plate. The elastic plate will deform when subjected to an external force, while the rigid plate will deform very little when subjected to an external force.

[0070] The waste liquid in the reaction chamber falls on the elastic plate, which plays a buffering role, which can not only reduce the splashing of the waste liquid, but also reduce the noise of the falling waste liquid; the rigid plate mainly plays a supporting role, ensuring the overall strength of the pressure plate 8, and at the same time can apply a stable downward pressure to the waste liquid.

[0071] In some embodiments, a limit plate 11 is provided in the first chamber 5 to limit the descending height of the pressing plate 8 to prevent the pressing plate 8 from exerting excessive pressure on the waste liquid and damaging the filter screen 9 .

[0072] The limiting plate 11 may be disposed directly opposite to the channel 15 , or may be disposed away from the channel 15 .

[0073] In the embodiment in which the position of the limit plate 11 corresponds to the channel 15, the thickness of the limit plate 11 along the direction perpendicular to the inner wall of the first warehouse body 5 is greater than the dimension of the channel 15 along the direction perpendicular to the inner part of the first warehouse body 5, so that when the pressure plate 8 descends to the position of the limit plate 11, the limit plate 11 can limit the descending height of the pressure plate 8; and when the height of the pressure plate 8 is higher than the height of the limit plate 11, the waste liquid falling through the channel 15 will fall on the upper end surface of the limit plate 11, which will buffer the falling of the waste liquid, reduce the impact of the waste liquid on the filter net 9 when it falls on the filter net 9, and protect the filter net 9.

[0074] Optionally, the upper end surface of the limiting plate 11 is a downwardly inclined guide surface.

[0075] There are many ways to open the gate 20 of the slag discharge port 13. In some embodiments of the present solution, the gate 20 of the slag discharge port 13 is opened and closed by a second drive assembly. Specifically, the second drive assembly includes a vertical channel 23, a pull rope 19, a retaining ring 16, a T-shaped pull rod 18 and a spring 17, wherein the vertical channel 23 is opened on the warehouse wall of the first warehouse body 5, and the opening direction of the vertical channel 23 is consistent with the movement direction from the open state to the closed state. When the gate 20 is opened, the gate 20 will move into the vertical channel 23;

[0076] The first end of the pull rope 19 is located in the vertical channel 23, and the second end of the pull rope 19 is located outside the vertical channel 23. A hole for the first end of the pull rope 19 to enter is opened on the vertical channel 23, and the second end of the pull rope 19 is used for the user to hold;

[0077] The retaining ring 16 is fixed in the vertical passage 23. A through hole is provided on the retaining ring 16 for the second end of the pull rope 19 to pass through. The second end of the pull rope 19 passes through the through hole on the retaining ring 16 and is connected to the T-shaped pull rod 18.

[0078] The T-shaped pull rod 18 includes a vertical rod 22 and a horizontal plate. The horizontal plate is located below the retaining ring 16. The vertical rod 22 is located below the horizontal plate. The horizontal plate is connected to the second end of the pull rope 19. The pull rope 19 pulls the T-shaped pull rod 18 to move up and down in the vertical channel 23.

[0079] The spring 17 is located between the horizontal plate and the retaining ring 16. When the pull rope 19 pulls the T-shaped pull rod 18 to move upward in the vertical channel 23, the gate 20 opens and the horizontal plate squeezes the spring 17. After the pull rope 19 is released, the T-shaped pull rod 18 moves downward under the restoring force of the spring 17, and the gate 20 is closed.

[0080] The reaction chamber is located above the filtering chamber, and the reaction chamber is connected to the filtering chamber through a discharge valve 4. The discharge valve 4 is opened or closed to control whether the reaction chamber is connected to the filtering chamber or not.

[0081] The reaction chamber includes a second chamber body 1, a stirring rod 14, a fixed rod 21 and a vertical rod 22, wherein the second chamber body 1 is connected to the first chamber body 5 through a discharge valve 4; the stirring rod 14 is located in the second chamber body 1, and the stirring rod 14 is arranged in the horizontal direction. There are multiple stirring rods 14, and the multiple stirring rods 14 are arranged side by side and spaced apart in the vertical direction. The multiple stirring rods 14 are connected to the second motor 2 through the vertical shaft 3, and the second motor 2 drives the vertical shaft 3 to rotate, and the vertical shaft 3 drives the multiple stirring rods 14 to rotate in the second chamber body 1; the fixed rod 21 and the vertical rod 22 form a T-bar structure, the fixed rod 21 is installed in the second chamber body 1 and is arranged in the horizontal direction, the fixed rod 21 and the stirring rod 14 are staggered in the vertical direction, and the middle part of the vertical rod 22 is connected to the fixed rod 21.

[0082] The T-bar structure composed of the fixed rod 21 and the vertical rod 22 does not move during the stirring process, and only the stirring rod 14 rotates. The T-bar structure provides resistance to the movement of the waste liquid to form a movement difference and improve the stirring effect.
