Description

Technical Field

[0001] This utility model relates to the field of fly ash treatment technology in power plants, and more specifically, to a fly ash treatment device for waste incineration power plants. Background Technology

[0002] In people's daily lives, a large amount of garbage is inevitably generated. If this garbage is not effectively treated, it will greatly affect people's living environment and even threaten people's health. At present, incineration is one of the main ways to deal with garbage. However, in the process of incinerating garbage, in addition to causing secondary environmental pollution, it will also waste resources and energy. Therefore, in the garbage disposal process, garbage incineration power generation can be adopted. However, a large amount of fly ash will be generated during the garbage incineration process, so fly ash needs to be treated.

[0003] Among them, the patent with announcement number CN215001610U discloses a fly ash treatment device for a waste incineration power plant, including an incineration chamber body, a smoke guide hood fixedly installed on the top of the incineration chamber body, an installation frame fixedly installed on the right side of the incineration chamber body, a suction pipe fixedly installed on the right side of the installation frame, a motor fixedly installed on the right side of the suction pipe, a bearing seat fixedly installed on the right side wall of the inner cavity of the suction pipe, a rotating shaft fixedly connected to the output shaft of the motor, a suction fan fixedly installed on the outside of the rotating shaft, a water storage tank fixedly installed on the top of the suction pipe, and a water outlet pipe connected to the bottom of the water storage tank. The fly ash treatment device for this waste incineration power plant uses a suction pipe. When the user is using it, the fly ash generated by combustion in the incineration chamber is discharged from the right side of the smoke hood under the action of the smoke guide hood. However, this structure is not easy to collect fly ash impurities that are scattered in the air during use, resulting in the dust and impurities generated by combustion in the power plant being discharged by the airflow, resulting in poor fly ash collection and treatment effect. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fly ash treatment device for waste incineration power plants, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a fly ash treatment device for waste incineration power plants, including a support column, on which a treatment component is provided; The processing component includes a water tank mounted on a support column. Several drainage hoppers are distributed at the bottom of the water tank, and a support frame is provided on one side of the bottom of each drainage hopper. A filter screen for collecting fly ash is embedded in the support frame, and a collection pipe is provided at the bottom of multiple support frames. One end of each of the multiple gathering tubes is rotatably connected to an arc support, and a support frame is rotatably connected between each pair of adjacent arc supports. A crossbar is provided on the top of the support frame, and several springs are provided on the crossbar, with the bottom end of each spring hooked onto the support frame. As can be seen, in the above technical solution, the airflow comes into contact with the filter screen and is filtered by the filter screen, which filters the fly ash and impurities onto the filter screen. The water stored in the water tank is diverted by the drain bucket and then transported to the filter screen, which washes the fly ash and impurities on the filter screen into the collection pipe. This not only cleans the filter screen, but also effectively prevents fly ash from sticking to the filter screen and causing poor subsequent collection effect of the filter screen. Optionally, in a possible implementation, a support plate is fitted on the support column, the support plate is located at the bottom of the water tank, and a plurality of electric push rods are hinged to the outside of the support plate. The output ends of the plurality of electric push rods are connected to two deflection rods, and one end of each deflection rod extends to the end of the crossbar and is hinged to the crossbar. A water collection hopper is provided on the support column, and two joints are fixedly provided at the bottom of the water collection hopper. A first hose is installed on each joint by a clamp. A second hose is installed at one end of a plurality of collection tubes by a flange, and the bottom end of each second hose extends into the water collection hopper. As can be seen, in the above technical solution, the water containing fly ash impurities is gathered by the gathering pipe and then discharged through the second hose, while the water gathering hopper gathers the water transported by the second hose and then discharges it through the first hose, which makes it easier for staff to centrally treat the discharged fly ash impurities, making the flue gas emitted by the power plant more environmentally friendly.

[0006] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, the overall design is simple and the structure is reasonable by setting up processing components. Through the corresponding cooperation of various structures, the airflow comes into contact with the filter screen and is filtered by the filter screen, which filters fly ash and impurities onto the filter screen. The water stored in the water tank is diverted through the drain hopper and then transported to the filter screen, which washes the fly ash and impurities on the filter screen into the collection pipe. This not only cleans the filter screen, but also effectively prevents fly ash from sticking to the filter screen and causing poor subsequent collection effect. Simultaneously, water containing fly ash impurities is gathered by the gathering pipe and discharged through the second hose. The water collection hopper gathers the water delivered by the second hose and discharges it through the first hose. This facilitates centralized treatment of the discharged fly ash impurities by the staff, making the flue gas emitted by the power plant more environmentally friendly. Furthermore, the crossbar, support frame, and gathering pipe can rotate around the axis point at the connection between the arc support and the support frame, realizing the function of adjusting the angle of the support frame and the filter screen. This allows each filter screen to be set at an angle, making it easy to gather the airflow sprayed onto the filter screen and ensure the fly ash treatment effect. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] As attached Figure 1 - Figure 5The waste incineration power plant fly ash treatment device shown uses a treatment component mounted on a support column 1 to filter the airflow through a filter screen 5, trapping fly ash and impurities on the screen. Water stored in the water tank 2 is diverted through a drain hopper 3 and then transported to the filter screen 5, flushing the fly ash and impurities onto the screen 5 into a collecting pipe 6. This cleans the filter screen 5 and effectively prevents fly ash from adhering to it, thus improving its subsequent collection efficiency. Meanwhile, the water containing fly ash and impurities is collected by the collecting pipe 6 and discharged through a second hose 17. The water collection hopper 14 collects the water transported by the second hose 17 and discharges it through a first hose 16, facilitating centralized treatment of the discharged fly ash and impurities by staff. This makes the flue gas emitted by the power plant more environmentally friendly. The specific structural configuration of the components is as follows. The processing component includes a water tank 2 installed on a support column 1. Several drainage hoppers 3 are distributed at the bottom of the water tank 2, and a support frame 4 is provided on one side of the bottom of each drainage hopper 3. A filter screen 5 for collecting fly ash is embedded in the support frame 4, and a collection pipe 6 is provided at the bottom of the multiple support frames 4. One end of each of the multiple gathering tubes 6 is rotatably connected to an arc support 8, and a support frame 7 is rotatably connected between each pair of adjacent arc support 8. A crossbar 9 is provided on the top of the support frame 4, and several springs 10 are provided on the crossbar 9, with the bottom end of each spring 10 hooked onto the support frame 4. A support plate 11 is fitted on the support column 1. The support plate 11 is located at the bottom of the water tank 2. Several electric push rods 12 are hinged to the outside of the support plate 11. The output ends of the multiple electric push rods 12 are connected to two deflection rods 13. One end of each deflection rod 13 extends to the end of the crossbar 9 and is hinged to the crossbar 9. A water collection hopper 14 is provided on the support column 1. Two connectors 15 are fixedly provided at the bottom of the water collection hopper 14. A first hose 16 is installed on each connector 15 by a clamp. A second hose 17 is installed on one end of multiple gathering pipes 6 by a flange. The bottom end of each second hose 17 extends into the water collection hopper 14.

[0016] According to the above structure, when in use, the staff installs the device at the power plant's exhaust vent. When collecting and treating fly ash and impurities in the air, the airflow comes into contact with the filter screen 5 and is filtered by the filter screen 5, which filters the fly ash and impurities onto the filter screen 5. The water stored in the water tank 2 is diverted through the drain hopper 3 and then transported to the filter screen 5, flushing the fly ash and impurities filtered on the filter screen 5 into the collection pipe 6. This not only cleans the filter screen 5 but also effectively prevents fly ash from adhering to the filter screen 5 and causing poor subsequent collection effect of the filter screen 5. Meanwhile, water containing fly ash impurities is gathered by the gathering pipe 6 and discharged through the second hose 17, while the water gathering hopper 14 gathers the water transported by the second hose 17 and discharges it through the first hose 16, making it easier for staff to centrally treat the discharged fly ash impurities, making the flue gas emitted by the power plant more environmentally friendly. Furthermore, the electric push rod 12 drives the deflection rod 13 to move. When the deflection rod 13 deflects at the output end of the electric push rod 12, it drives the crossbar 9, the support frame 4 and the gathering tube 6 to rotate along the axis point at the connection between the arc support 8 and the support frame 7, thereby realizing the function of adjusting the angle of the support frame 4 and the filter screen 5, so that each filter screen 5 can be set at an angle, which makes it easy to gather the airflow sprayed onto the filter screen 5 and ensure the fly ash treatment effect.

[0017] Unlike existing technologies, this application discloses a fly ash treatment device for waste incineration power plants. Airflow is filtered through a filter screen 5, trapping fly ash and impurities on the screen. Water stored in the water tank 2 is diverted through a drain hopper 3 and then transported to the filter screen 5, flushing the fly ash and impurities onto the screen 5 into a collecting pipe 6. This effectively cleans the filter screen 5 and prevents fly ash from adhering to it, thus improving subsequent collection efficiency. Simultaneously, the water containing fly ash and impurities is collected by the collecting pipe 6 and discharged through a second hose 17. The water collecting hopper 14 collects the water from the second hose 17 and discharges it through a first hose 16, facilitating centralized treatment of the discharged fly ash and impurities by staff, resulting in more environmentally friendly flue gas emissions from the power plant.

[0018] 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.
