Technical Field
[0001] This utility model relates to the technical field of wet electrostatic precipitators, specifically to an inlet device for a wet electrostatic precipitator. Background Technology
[0002] Wet electrostatic precipitators are a new type of dust removal equipment used to treat dust and microparticles. They are mainly used to remove harmful substances such as dust, acid mist, water droplets, aerosols, odors, and PM2.5 from humid gases. They are ideal equipment for controlling atmospheric dust pollution and are widely used in power plant flue gas treatment.
[0003] Existing patent CN220405953U discloses an inlet device for a wet electrostatic precipitator, applicable to the field of wet electrostatic precipitator inlets. It includes an inlet pipe, one side of which is connected to a conveying pipe. This invention uses a drive motor to drive two bevel gears (one and two sides) to rotate forward or reverse. The first bevel gear drives a screw to rotate forward or reverse, which in turn drives a guide component (two sides) to change position. By adjusting the distance between the guide component (two sides) and the first guide component (one side), the gas delivery volume can be controlled, ensuring that gas does not accumulate when entering the wet electrostatic precipitator through the conveying pipe. This helps stabilize the dust removal effect, efficiency, and energy consumption of the wet electrostatic precipitator. By setting up the guide component (one side), the guide component (two sides), the drain pipe, and the inlet pipe, condensate from the guided gas can be accumulated and discharged from the inside of the conveying pipe, reducing the amount of condensate generated in the conveying pipe and decreasing the corrosion of the conveying pipe by the condensate.
[0004] Based on the search of the aforementioned patents and in conjunction with the inlet devices in the prior art, it was found that although the aforementioned inlet devices can control the air intake and spray and cool the flue gas during use, the cooled water is discharged mixed with impurities. This mixed water is not easy to recycle, resulting in water waste and thus insufficient practicality. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. By setting up an air inlet pipe, an air delivery pipe, a water tank, and circulation components, the water pump can draw water from the water tank, cool it through a condenser, and then spray it out through an atomizing nozzle.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model provides a technical solution: an inlet device for a wet electrostatic precipitator, including an inlet pipe 1 and an outlet pipe 11. A water tank 12 is fixedly connected to the bottom of the outlet pipe 11. A circulation component is provided inside the water tank 12, and an adjustment component is provided inside the outlet pipe 11. The circulation component includes a filter plate 21 fixedly connected to the inner wall of the water tank 12, a horizontal plate 22 fixedly connected to one side of the water tank 12, a water pump 23 fixedly connected to the top of the horizontal plate 22, a water pump pipe 24 fixedly connected to one side of the water pump 23, a first outlet pipe 25 fixedly connected to the other side of the water pump 23, a condenser 26 fixedly connected to the first outlet pipe 25, a second outlet pipe 27 fixedly connected to one side of the condenser 26, and a second outlet pipe 27... The system includes a fixed third water outlet pipe 28, multiple atomizing nozzles 29 evenly arranged on one side of the third water outlet pipe 28, and a cleaning component for processing the filter plate 21. A water pump 24 is connected to a water tank 12. A second water outlet pipe 27 passes through and extends into the air supply pipe 11. When the water pump 23 is started, water is drawn from the water tank 12, cooled by the condenser 26, and then discharged into the second and third water outlet pipes 27 and 28. The water is then sprayed out through the atomizing nozzles 29, cooling the flue gas and removing solid impurities. The mixed water falls into the water tank 12 and is filtered by the filter plate 21. The filtered water can be recycled, avoiding water waste. The cleaning components include a motor 41 fixedly connected to one side of the water tank 12, a lead screw 42 fixedly connected to the output end of the motor 41, a movable plate 43 connected to the outside of the lead screw 42, and a cleaning brush 44 fixedly connected to the bottom of the movable plate 43. The lead screw 42 is screwed to the movable plate 43 and is rotatably connected to the water tank 12. When the motor 41 is started, it can control the lead screw 42 to rotate, which in turn can move the movable plate 43, thereby driving the cleaning brush 44 to move. This allows the cleaning brush 44 to clean the impurities on the top of the filter plate 21, thus unclogging the filter plate 21 and ensuring its filtration performance. A fixing rod 81 is fixedly connected to the inner wall of the water tank 12. The fixing rod 81 passes through the movable plate 43 and is slidably connected to the movable plate 43. The fixed rod 81 can stop the movement of the moving plate 43, preventing the moving plate 43 from rotating synchronously with the lead screw 42, thus ensuring the stable back-and-forth movement of the cleaning brush 44. A discharge port 61 is provided on one side of the water tank 12, and a baffle plate 62 is inserted into the discharge port 61. A handle 63 is fixedly connected to one side of the baffle plate 62. The handle 63 can drive the baffle plate 62 to move, allowing the baffle plate 62 to be inserted into or removed from the discharge port 61, which facilitates the discharge of impurities from the top of the filter plate 21 and prevents impurities from accumulating. A drain pipe 71 is fixedly connected to one side of the water tank 12, and a control valve 72 is installed on the drain pipe 71. The control valve 72 can control the opening and closing of the drain pipe 71, thus facilitating the discharge of water from the water tank 12.
[0025] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5 The adjusting components include a support plate 31 fixedly connected to the inner wall of the air supply pipe 11, an electric push rod 32 fixedly connected to the top of the support plate 31, an adjusting plate 33 fixedly connected to the bottom of the electric push rod 32, and a support component for improving the stability of the adjusting plate 33's movement. The electric push rod 32 can drive the adjusting plate 33 to move vertically when activated, which can adjust the air intake of the air inlet pipe 1 and control the air intake to prevent excessive air intake from affecting the normal use of the equipment. The support component includes support rods 51 fixedly connected to the top two sides of the adjusting plate 33 and openings 52 respectively opened on the top two sides of the support plate 31. The support rods 51 are slidably connected to the openings 52 and can slide within the openings 52, which can guide and support the vertical movement of the adjusting plate 33 and prevent the adjusting plate 33 from tilting.
[0026] Working principle: During operation, water pump 23 is started, and water pump 23 draws water from water tank 12 through water pipe 24, and then discharges it into condenser 26 for cooling. The cooled water is discharged into second outlet pipe 27, then into third outlet pipe 28, and then sprayed out through atomizing nozzle 29 to cool the flue gas in gas pipe 11 and remove solid impurities. The mixed water falls onto the top of filter plate 21 in water tank 12, where it filters impurities. The filtered water can be recycled. When it is necessary to clean filter plate 21, the baffle plate 62 is removed by handle 63, and motor 41 is started to drive lead screw 4. 2. Rotation of the lead screw 42 can drive the moving plate 43 to move, which in turn drives the cleaning brush 44 to move. The cleaning brush 44 can clean the impurities on the top of the filter plate 21, allowing the impurities to be discharged through the discharge port 61. Then, the baffle plate 62 is inserted into the discharge port 61 again. When it is necessary to adjust the air intake, the electric push rod 32 is activated, which can push the adjusting plate 33 to move vertically, thereby adjusting the air intake diameter of the air intake pipe 1 to prevent excessive air intake from affecting the normal use of the equipment. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
