More and more enterprises, responding to the call of national policies, have tried every means and taken actions. At present, in order to meet the emission standards, existing polluting enterprises have launched desulfurization, denitrification, and wet electrostatic precipitation projects one after another. Among them, the wet electrostatic precipitator in the dust removal project has the advantages of high purification efficiency, simple operation and maintenance, small occupied space, simple and convenient maintenance, and stable dust removal effect. In order to improve the use safety of wet electrostatic precipitators and reduce potential hazards, safety issues need to be considered for all components inside the wet electrostatic precipitator.

[0003] The original liquid drainage bottom plate of the traditional wet electrostatic precipitator is of an integral structure with a small radian, which is prone to dust and liquid accumulation. Long-term dust and liquid accumulation will cause phenomena such as the liquid drainage bottom plate sagging and deforming, and corrosion and perforation, increasing potential safety hazards of the wet electrostatic precipitator. Therefore, in view of the above problems, a novel liquid drainage plate for wet electrostatic precipitators is proposed to solve the above problems. Summary of the Invention

[0004] In order to make up for the above deficiencies, the utility model provides a novel liquid drainage plate for wet electrostatic precipitators, aiming to improve the problem that the traditional liquid drainage bottom plate of wet electrostatic precipitators is prone to dust and liquid accumulation due to its small radian in the prior art.

[0024] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0025] Refer to Figures 1 to 3 , an embodiment provided by the present invention: a new type of drain plate for a wet electrostatic precipitator, including a circular protective cover 1. The circular protective cover 1 is made of polypropylene. Polypropylene has excellent chemical corrosion resistance and can withstand the erosion of many acids, alkalis and solvents. Therefore, it is widely used in occasions such as chemical industry and electrostatic precipitation that require corrosion resistance, which can increase the service life of this drain plate.

[0026] In the middle of the inside of the circular protective cover 1, a bottom inclined plate 2 is fixedly connected. The bottom inclined plate 2 is fan-shaped and can accelerate the discharge of accumulated dust and liquid. On both the front and rear sides of the inside of the circular protective cover 1, flank inclined plates 3 are fixedly connected. The inclination of the two flank inclined plates 3 is high, and most of the dust and waste liquid can be discharged to the middle bottom inclined plate 2. The outer top end of the bottom inclined plate 2 is made of fluoroplastic coating material, and the outer top end of the flank inclined plate 3 is made of fluoroplastic coating material. The fluoroplastic coating has good corrosion resistance and mechanical strength, and the surface is smooth and easy to clean. This coating helps this drain plate to drain liquid better.

[0027] Refer to Figure 2 , Figure 3 , on the outside of the right side of the circular protective cover 1, a drain pipe orifice 4 is fixedly connected. The drain pipe orifice 4 passes through the inner wall of the dust collector and is connected to the outside, so that the dust and liquid accumulated on the bottom inclined plate 2 and the flank inclined plates 3 can be discharged along the inclined surfaces of the bottom inclined plate 2 and the flank inclined plates 3. At the bottom end of the circular protective cover 1, three fixed arc plates 5 are fixedly connected. The circular protective cover 1 is embedded in the inner wall of the dust collector, and can drive the bottom inclined plate 2 and the flank inclined plates 3 to be closely attached to the inner wall of the dust collector for installation.

[0028] Refer to Figure 4, two mounting holes 6 are provided in the middle of the fixed arc plate 5. The fixed arc plate 5 can be mounted on the inner wall of the dust collector through the mounting holes 6. A triangular support block 7 is fixedly connected to the inner side of the outside of the fixed arc plate 5. The triangular support block 7 is fixed in the middle of the fixed arc plate 5 to form a stable support force. A support assembly is provided at the top end of the fixed arc plate 5 to enhance the rigidity-bearing capacity of the circular protective sleeve 1.

[0029] The support assembly includes a support plate 8. The top end of the support plate 8 is fixedly connected to the bottom end of the circular protective sleeve 1. The bottom end of the support plate 8 is fixedly connected to the top end of the triangular support block 7. One side of the support plate 8 close to the triangular support block 7 is fixedly connected to the outer top end of the fixed arc plate 5. The support plate 8 conducts the impact force of the falling waste liquid of the drain plate hand-operated to the fixed arc plate 5 and the triangular support block 7. Two support rods 9 are fixedly connected to the bottom end of the support plate 8. The bottom ends of the support rods 9 are fixedly connected to one side of the fixed arc plate 5 close to the triangular support block 7. The support rods 9 increase the support force of the fixed arc plate 5.

[0030] Working principle: When the accumulated liquid and dust in the dust collector fall, they will pass through the high-slope side plate wing slant plates 3 on both sides to guide the dust and waste liquid inside the dust collector to the bottom slant plate 2 of the middle fan-shaped bottom plate. Then the dust and waste liquid will accelerate and discharge along the inclined surface shape of the bottom slant plate 2. Finally, all the accumulated dust and liquid will be discharged through the centralized discharge port drain pipe orifice 4, thereby reducing problems such as the downward deformation and corrosion perforation of the bottom plate.

[0031] When installing this drain plate, first align the top fixed arc plate 5 with the installation position embedded in the dust collector tower wall to position and install the circular protective sleeve 1, and then connect it to the inside of the dust collector through bolts passing through the mounting holes 6. At this time, install the bottom slant plate 2 at the opening position of the drain pipe orifice 4 and perform spot welding fixation. After the spot welding of the bottom slant plate 2 is completed, install the two side wing slant plates 3, and still perform spot welding fixation first. After all the fixations are completed, perform full welding construction. After the full welding construction is completed, inspect the welds, and perform touch-up painting after reaching the acceptance standard. Thus, the installation of this drain plate is completed.

[0032] During use, when the bottom slant plate 2 of the bottom plate and the side slant plates wing slant plates 3 on both sides are impacted by liquid, the support plate 8 at the bottom and the fixed arc plate 5 provide support for the bottom slant plate 2 and the wing slant plates 3 inside the drain plate through the support structure triangular support block 7, support plate 8, and support rods 9. This helps to disperse and transfer the pressure, enhance the structural stability, reduce deformation and inclination, and ensure the normal operation of the equipment.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
