[0002] In the operation of thermal power plants, existing flue gas dust removal technologies have many problems. Traditional bag filters are prone to clogging, leading to a decrease in dust removal efficiency. Moreover, replacing the filters is cumbersome and costly. While water film filters can remove some dust, they consume a lot of water and the wastewater generated is difficult to treat, easily causing secondary pollution. In addition, electrostatic precipitators are not effective in treating high resistivity dust and pose safety hazards. These problems not only affect the normal production of thermal power plants but also make it difficult to meet increasingly stringent environmental protection requirements, bringing certain adverse effects to users. In order to overcome the shortcomings of existing technologies, we propose an environmentally friendly flue gas dust removal device for thermal power plants. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The environmentally friendly flue gas dust removal device used in this thermal power plant achieves efficient filtration and adsorption of dust in the flue gas through the coordinated operation of filter elements and mist nozzles. The filter elements initially filter the dust, while the water droplets sprayed from the mist nozzles further adsorb the remaining dust, greatly improving the dust removal efficiency. At the same time, the device has a water recycling function. The water filtered by the filter plates flows back to the bottom of the dust collection box and is pumped out for recycling, which reduces water waste and lowers operating costs, conforms to the concept of environmental protection, and effectively improves the environmental protection level of flue gas treatment in thermal power plants.

[0013] 2. This thermal power plant uses an environmentally friendly flue gas dust removal device. When the filter element needs to be replaced, simply remove the bolts and pull the mounting plate to easily remove the filter element assembly. The unique snap-fit ​​structure makes filter element disassembly and installation simple. Rotating the filter element causes the snap-fit ​​block to retract, allowing for quick filter element replacement without the need for complicated tools or professional skills. This convenient replacement method shortens equipment maintenance time, reduces the impact of equipment downtime on production, improves the production efficiency of the thermal power plant, and provides a strong guarantee for the stable operation of the flue gas dust removal equipment in the thermal power plant.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-2 As shown, an environmentally friendly flue gas dust removal device for thermal power plants is described. When using this device, the flue gas exhaust pipe of the thermal power plant is first connected to the inlet pipe 22. At this time, the flue gas enters the dust collection box 1 through the inlet pipe 22. In the dust collection box 1, the filter element 10 performs preliminary filtration of the flue gas, intercepting larger dust particles. Then, the water pump 17 is started, drawing water from the bottom of the dust collection box 1. The water is transported to the distribution box 19 through the water pipe 18. The distribution box 19 then... Several evenly distributed mist nozzles 20 spray water in a mist form. These mist water droplets adsorb dust in the flue gas, causing the dust to fall onto the surface of the filter plate 21 along with the water droplets. After being filtered by the filter plate 21, the water drips to the bottom of the dust collection box 1 and is then pumped out by the water pump 17 for recycling. At the same time, the mist nozzles 20 can also wash the dust attached to the filter element 10 during spraying, preventing excessive dust on the filter element 10 from affecting the flue gas filtration efficiency. Finally, the flue gas that has undergone dust removal is discharged to the outside through the exhaust pipe 23.

[0022] Example 2, as Figures 1-5As shown, an environmentally friendly flue gas dust removal device for thermal power plants requires replacement of the filter element 10. First, the bolts 5 are removed from both sides of the dust collection box 1. Since the bolts 5 are used to fix the plug-in blocks 4, removing the bolts 5 releases the fixing of the mounting plate 3. Then, pulling the mounting plate 3 causes the two symmetrically arranged plug-in blocks 4 at the rear end of the mounting plate 3 to be pulled out from the plug-in slots 2 at the front end of the dust collection box 1. Simultaneously, the sliders 8 on both sides of the connecting plate 7 welded to the rear end of the mounting plate 3 slide along the symmetrically arranged slide rails 6 inside the dust collection box 1, thereby driving the connecting plate 7 and the filter element 10 out of the dust collection box 1. After removal, rotating the filter element 10 causes the connecting blocks 12 on both sides of the filter element 10 to move along with it. As the filter element 10 rotates, the locking block 16, being a hemisphere, engages with the locking groove 11 inside the through hole 9. When the filter element 10 rotates and moves the connecting block 12, the locking block 16 will cause the limiting plate 15 to retract into the inner cavity 13 inside the connecting block 12. At the same time, it will compress the spring 14 inside the inner cavity 13. After rotating to a certain angle, the locking block 16 will completely retract into the inner cavity 13. At this time, the filter element 10 can be lifted upwards and removed from the center of the through hole 9. Then, a new filter element 10 is inserted into the through hole 9, and the locking block 16 engages with the locking groove 11 under the action of the spring 14, thus completing the replacement of the filter element 10.
