Description

Technical Field

[0001] This utility model belongs to the field of wet desulfurization technology, specifically relating to an efficient collection device for flushing water of a desulfurization tower demister with an N-type structure. Background Technology

[0002] In modern industry, wet desulfurization (WDF) has become the mainstream technology for flue gas desulfurization in coal-fired power plants, steel smelting, and other industries due to its high efficiency. The demister, as a core component, bears the heavy responsibility of removing liquid droplets carried in the desulfurized flue gas; its stable operation directly affects the efficiency and environmental compliance of the desulfurization system. To prevent the demister from being affected by ash and scale buildup, it needs to be flushed regularly. However, the proper treatment of this flushing water is crucial for maintaining the water balance within the desulfurization tower. Currently, most wet WDF systems directly discharge the demister flushing water into the desulfurization tower for circulation. This irregular addition of flushing water disrupts this balance. The timing and volume of flushing water entering the desulfurization tower are difficult to match with the actual needs of the system, leading to frequent and drastic fluctuations in the tower's liquid level. When the desulfurization tower's drainage volume increases significantly due to water balance imbalance, the wastewater treatment system will operate under overload for extended periods. This not only significantly reduces treatment efficiency, preventing the full treatment of pollutants in the wastewater, but also greatly increases treatment costs. Therefore, an efficient collection device for flushing water of the desulfurization tower demister with an N-type structure is proposed to solve the above problems. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0017] Implementation

[0018] Please see Figure 1 -5. A high-efficiency collection device for flushing water of a desulfurization tower demister with an N-type structure, comprising: Desulfurization tower body 1; A water spray unit is fixedly installed inside the main body 1 of the desulfurization tower for rinsing the demister; The demister body 2 is fixedly installed inside the desulfurization tower body 1 to remove mist droplets; A flushing water collection unit is fixedly installed inside the main body 1 of the desulfurization tower for efficient collection of flushing water; The flushing water collection unit includes a fixed plate 3 fixedly installed inside the desulfurization tower body 1, a fixed rod 4 fixedly installed inside the fixed plate 3, a water collection trough 5 fixedly installed at one end of the fixed rod 4, an N-shaped water collection blade 6 fixedly installed on one side of the fixed plate 3, a connection hole 7 opened inside the water collection trough 5, and a guide pipe 8 fixedly installed on one side of the desulfurization tower body 1. One end of the N-shaped water collection blade 6 is inserted into the connection hole 7 opened inside the water collection trough 5.

[0019] The technical solution provided in this embodiment is as follows: flue gas enters the interior of the demister body 2 from bottom to top through the N-type water collecting blades 6. The water pump 9 is started to draw water through the water supply pipe 10. When the demister body 2 is washed through the water outlet pipe 11 and the flushing nozzle 12, the flushing water will fall into the groove of the N-type water collecting blades 6. Each N-type water collecting blade 6 is installed at a certain angle. After the flushing water falls on the demister body 2, it is collected by the N-type water collecting blades 6 and then flows into the interior of the water collection tank 5. After the water collection tank 5 collects the flushing water, it flows into the interior of the guide pipe 8, thereby collecting the flushing water and sending it to the collection water tank outside the tower.

[0020] Furthermore, the water spraying unit includes a water pump 9 fixedly installed on one side of the desulfurization tower body 1, a water supply pipe 10 fixedly installed at the input end of the water pump 9, a water outlet pipe 11 fixedly installed at the output end of the water pump 9, and a flushing nozzle 12 fixedly installed inside the water outlet pipe 11, with the water outlet of the flushing nozzle 12 facing directly downwards.

[0021] Specifically, by fixing the water pump 9 to one side of the desulfurization tower body 1, the water pump 9 can easily flow the flushing water into the interior of the desulfurization tower body 1 through the water outlet pipe 11. By setting the water outlet of the flushing nozzle 12 to face directly downward, the flushing nozzle 12 can be used to flush the demister body 2.

[0022] Furthermore, the interior of the demister body 2 includes a fixed frame 13 fixedly installed inside the desulfurization tower body 1, and a corrugated plate 14 fixedly installed inside the fixed frame 13.

[0023] Specifically, by installing a corrugated plate 14 inside the fixed frame 13, the mist droplets inside the flue gas can be impacted by the corrugated plate 14, thereby filtering out the mist droplets inside the flue gas.

[0024] Furthermore, a drain pipe 15 is fixedly installed on one side of the desulfurization tower body 1, and a filter plate 16 is fixedly installed at one end of the drain pipe 15.

[0025] Specifically, by fixing the filter plate 16 to one end of the drain pipe 15, some impurities can be filtered out, preventing solid impurities from clogging the drain pipe 15.

[0026] Furthermore, an outlet 17 is fixedly installed on the top of the desulfurization tower body 1, and the outlet 17 is in a horizontal direction.

[0027] Specifically, by setting the outlet 17 to a horizontal direction, it is possible to prevent substances ejected from the outlet 17 from falling onto the top of the desulfurization tower when they fall from the air, thereby preventing the substances from contaminating the desulfurization tower.

[0028] Furthermore, the flushing water collection unit is located directly below the demister body 2, and the flushing nozzle 12 is located directly above the demister body 2.

[0029] Specifically, by placing the flushing water collection unit directly below the demister body 2, when the flushing nozzle 12 sprays water to flush the demister body 2, the flushing water drips onto the N-type water collection blade 6, and then flows into the water collection tank 5 through the connection hole 7. Then, the flushing water is discharged into the desulfurization tower body 1 through the guide pipe 8 to prevent the time and amount of flushing water entering the desulfurization tower from being difficult to match with the actual needs of the system, which would cause frequent and violent fluctuations in the liquid level inside the tower.

[0030] Furthermore, multiple N-type water-collecting blades 6 are stacked on top of each other, and a gap is reserved between every two N-type water-collecting blades 6.

[0031] Specifically, by reserving gaps between every two N-type water-collecting blades 6, the flue gas can enter the interior of the demister body 2 through the gaps, and then the mist droplets inside the flue gas can be removed by the demister body 2.

[0032] Furthermore, one end of the guide pipe 8 is fixedly connected to the water collection tank 5, and the guide pipe 8 is connected to the interior of the water collection tank 5.

[0033] Specifically, by fixing one end of the guide pipe 8 to the water collection tank 5 and connecting the guide pipe 8 to the inside of the water collection tank 5, the flushing water inside the water collection tank 5 can flow out through the guide pipe 8, preventing the flushing water from entering the interior of the desulfurization tower.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
