Technical Field

[0001] The utility model relates to the technical field of flushing wastewater sewage discharge devices, in particular to a wastewater collection and sewage discharge device for a desulfurization demister. Background Art

[0002] During the desulfurization process, many tiny droplets are entrained in the treated gas. If these droplets are discharged with the gas, on the one hand, it will cause waste of water resources, and on the other hand, the droplets may also contain some pollutants, which will pollute the environment and may also cause adverse effects such as corrosion to subsequent equipment; the main function of the desulfurization demister is to remove these droplets entrained in the gas. Common desulfurization demisters include flat demisters, roof demisters and other types.

[0003] When it is necessary to treat the droplets generated during the desulfurization process, a demister is generally used, and the demister will also discharge wastewater during operation. At present, a large amount of dust-containing wastewater generated by most wet electrostatic spraying flushing and desulfurization tower demister flushing directly enters the desulfurization slurry, which will affect the slurry quality and reduce the service life of the slurry, and the practicability is not good; therefore, in order to solve the above problems, a wastewater collection and sewage discharge device for a desulfurization demister is hereby proposed.

Detailed implementation manner

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , a waste water collection and sewage discharge device for a desulfurization demister, comprising a housing 1 and a waste water collection mechanism. The waste water collection mechanism includes a first connecting rod 2. One end of the first connecting rod 2 is fixedly connected with a first triangular flow guide groove 3. The inside of the first triangular flow guide groove 3 is fixedly connected with a first water receiving tank 4. One end of the first water receiving tank 4 is fixedly connected with a pipeline 5. The inside of the housing 1 is fixedly connected with a second connecting rod 6. One end of the second connecting rod 6 is fixedly connected with a second water receiving tank 7. The inside of the second water receiving tank 7 is fixedly connected with a second triangular flow guide groove 8. The inside of the housing 1 is fixedly connected with a mounting bracket 9. The upper side of the mounting bracket 9 is fixedly installed with a demister body 10. A guiding groove 11 is opened inside the second triangular flow guide groove 8. The first connecting rod 2 is fixedly connected inside the housing 1. The second triangular flow guide groove 8 is arranged above the first triangular flow guide groove 3. The first triangular flow guide groove 3 and the second triangular flow guide groove 8 are arranged in a staggered manner. The device is arranged in a staggered labyrinth form between the first triangular flow guide groove 3 and the second triangular flow guide groove 8. The triangle plays the role of guiding the flue gas, collecting the accumulated water above with the largest area, ensuring the smooth passage of the flue gas while collecting the waste water containing dust and heavy metals washed down by the wet electrostatic precipitator and the demister. The collected waste water is sent to the waste water treatment system for treatment through the pipeline 5, and then sent to the desulfurization system after treatment. Installed at the lower spray outlet of the demister body 10 at the bottom layer, it solves the problem that a large amount of waste water containing dust generated by the wet electrostatic precipitator spray washing and the desulfurization tower demister washing does not directly enter the desulfurization slurry, thereby improving the slurry quality and increasing the service life of the slurry; the demister body 10 is a device used to separate liquid droplets and fog droplets in the gas flow in industrial production. In many industrial processes, such as the wet desulfurization process, absorption and distillation operations in chemical production, etc., the gas will carry a certain amount of liquid droplets or fog droplets during the flow process. The role of the demister is to separate these liquid droplets from the gas flow. From the perspective of structure and principle, common demisters include baffle demisters, wire mesh demisters, etc.

[0020] In one aspect of this embodiment, the notch 12 formed on the surface of the mounting frame 9 is located at the demisting opening of the demister body 10. The ventilation slot 13 facilitates the flow of gas, enabling the demister body 10 to operate better. When the flue gas containing droplets and impurities first enters the housing 1 through the first flue gas flow channel 14 on the lower surface of the housing 1, the flue gas after demisting treatment flows to the wet electrostatic precipitator through the second flue gas flow channel 15 on the upper surface of the housing 1 for subsequent treatment.

[0021] The working principle of the present utility model: When in use, for the waste water collection and drainage device of this desulfurization and demisting device, when the flue gas containing droplets and impurities first enters the housing 1 through the first flue gas flow channel 14 on the lower surface of the housing, two layers of demister bodies 10 are installed inside the housing 1, and the demister bodies 10 start to demist the flue gas. During the demisting process, a large amount of dust-containing waste water generated by wet electrostatic spraying and washing and the washing of the desulfurization tower demister flows to the waste water collection mechanism below during the washing process. The second triangular diversion groove 8 located in the upper layer and the first triangular diversion groove 3 located in the lower layer are arranged in an interleaved manner and in a staggered and labyrinthine layout. On the one hand, the triangle plays a role in guiding the flue gas; on the other hand, when the washing waste water falls, it collects the accumulated water above with the largest area. The waste water first flows into the first triangular diversion groove 3 and is then collected through the first water receiving groove 4 fixedly connected inside the first triangular diversion groove 3, and then the waste water is discharged through the pipeline 5. At the same time, the second water receiving groove 7 inside the second triangular diversion groove 8 in the upper layer also collects the waste water. The collected waste water will flow into the first water receiving groove 4 through the guiding groove 11 and then is also sent to the waste water treatment system through the pipeline 5 for treatment. The treated waste water is then sent to the desulfurization system to achieve the treatment and reuse of the waste water. During the whole process, the notch 12 formed on the surface of the mounting frame 9 is located at the demisting opening of the demister body 10. The ventilation slot 13 facilitates the flow of gas, enabling the demister body 10 to operate better. The flue gas after demisting treatment flows to the wet electrostatic precipitator through the second flue gas flow channel 15 on the upper surface of the housing 1 for subsequent treatment. All the electrical equipment in this solution is powered by an external power supply.

[0022] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described 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.
