Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, and in particular to an exhaust gas treatment device for an incinerator. Background Technology

[0002] The exhaust gas from incinerators needs to be treated primarily because the waste gas produced during the incineration process contains various harmful substances that pose a threat to the environment and human health. Therefore, a series of treatment measures must be implemented to reduce the emission of these harmful substances and ensure compliance with environmental standards.

[0003] A search revealed that patent document CN216395763U discloses an incinerator exhaust gas treatment device. This device, through the installation of a spraying mechanism, a collection mechanism, a filtering mechanism, and a driving mechanism, removes and collects most of the dust from the flue gas as it enters the exhaust gas duct. The filter installed in the exhaust gas duct filters out any remaining dust, resulting in excellent dust removal. Furthermore, the filter is self-cleaning and requires no replacement, reducing labor costs. This achieves a significant and superior dust removal effect on the flue gas transported in the exhaust gas duct of a waste liquid incinerator.

[0004] In actual use, the above-mentioned exhaust gas treatment device installs a filter screen in the exhaust pipe to clean and self-clean the dust in the exhaust gas. However, when the dust is conveyed by wind and squeezed by the cleaning roller, the dust that comes into contact with water is more likely to clog the inside of multiple filter holes, making it impossible to effectively clean the filter screen.

The multiple columnar activated carbons are rotated and switched by setting the switching mechanism.

[0010] Preferably, a drain pipe is fixedly connected to the bottom of the treatment box, and an electronic valve is fixedly sleeved on the outer wall of the drain pipe. The electronic valve is normally open and used for draining water from the treatment box.

[0011] Preferably, the outer wall of the disc is fixedly connected with multiple straight rods, one end of each straight rod being fixedly connected to the inner wall of the processing box, thereby supporting the disc by setting multiple straight rods.

[0012] Preferably, one end of each of the two connecting pipes is fixedly connected to a water pump.

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

[0024] Depend on Figures 1-4As shown, a tail gas treatment device for an incinerator is disclosed, comprising a treatment box 1, a drain pipe 2 fixedly connected to the bottom of the treatment box 1, an electronic valve 3 fixedly sleeved on the outer wall of the drain pipe 2, two docking holes opened on the outer wall of the treatment box 1, and docking pipes 4 fixedly connected to the inner walls of the two docking holes, and hollow discs 5 fixedly connected to one end of the two docking pipes 4, the two discs 5 being arranged vertically, multiple atomizing nozzles 7 on the upper disc 5 being used to spray lime water, and multiple atomizing nozzles 7 on the lower disc 5 being used to spray clean water, multiple straight rods 6 fixedly connected to the outer wall of the discs 5, one end of each straight rod 6 being fixedly connected to the inner wall of the treatment box 1, and multiple atomizing nozzles 7 evenly fixedly connected to the outer walls of the two discs 5, the multiple atomizing nozzles 7 being arranged in a ring.

[0025] The treatment box 1 is internally fixedly connected to an annular stainless steel plate 8, and an annular stainless steel filter screen 9 is internally fixedly connected to the annular stainless steel plate 8. The two annular stainless steel plates 8 are in a ring shape and support the stainless steel filter screen 9. The outer wall of the treatment box 1 is hinged to a box cover 15. The bottom of the box cover 15 is pressed against the top of the rotating placement seat 13. An existing lock is installed on the outer wall of the box cover 15 away from the hinge position. The box cover 15 is fixed to the top of the treatment box 1 by the lock. A corrugated pipe 16 is fixedly connected to the top of the box cover 15. One end of the corrugated pipe 16 is connected to an existing blower. The corrugated pipe 16 is located above the flow channel 12. Between the two is a columnar activated carbon 14.

[0026] The treatment box 1 is equipped with an exhaust gas inlet mechanism, which includes an exhaust gas inlet pipe 10. One end of each of the two connecting pipes 4 is fixedly connected to a water pump. The outer wall of the treatment box 1 is provided with an installation hole, and the inner wall of the installation hole is fixedly connected to the outer wall of the exhaust gas inlet pipe 10. A partition 11 is fixedly connected inside the treatment box 1. The outer wall of the partition 11 is provided with a flow channel 12. The flow channel 12 is circular and its diameter is smaller than that of the columnar activated carbon 14. The partition 11 assists the exhaust gas to enter the columnar activated carbon 14 through the flow channel 12.

[0027] The processing box 1 is equipped with a switching mechanism, which includes a rotating placement seat 13. A circular groove is provided on the top of the processing box 1. The inner wall of the circular groove is slidably connected to the outer wall of the rotating placement seat 13. An annular groove is provided on the top of the partition plate 11. A T-shaped ring is rotatably connected to the inner wall of the annular groove. The top of the T-shaped ring is fixedly connected to the bottom of the rotating placement seat 13. The T-shaped ring assists the rotating placement seat 13 in rotating. Multiple placement slots are provided on the top of the rotating placement seat 13. Columnar activated carbon 14 is placed on the inner wall of each of the multiple placement slots.

[0028] Working principle: During use, the exhaust gas inlet pipe 10 is connected to the exhaust gas outlet of the incinerator. One end of the corrugated pipe 16 is connected to the existing blower. The blower operates to create a suction process, accelerating the exhaust gas through the exhaust gas inlet pipe 10 into the treatment box 1. Two discs 5 are arranged vertically. Two water pumps respectively deliver clean water and lime water to the two discs 5 through two connecting pipes 4. Multiple atomizing nozzles 7 on the upper disc 5 spray lime water, while multiple atomizing nozzles 7 on the lower disc 5 spray clean water. The upper disc 5 treats sulfur dioxide in the exhaust gas, while the lower disc 5, after the bottom mesh of the stainless steel filter screen 9 is clogged, sprays high-speed water mist through multiple atomizing nozzles 7 to clean the stainless steel filter screen 9. The bottom of the chamber is cleaned to prevent blockage. Lime water is used to treat sulfur dioxide in the exhaust gas. Large dust particles in the exhaust gas are trapped at the bottom of the stainless steel filter screen 9. The impact force of the lime water spray cleans the top of the stainless steel filter screen 9, forming sediment at the bottom of the treatment box 1. This sediment is then discharged through the drain pipe 2. The exhaust gas passes through the flow channel 12 and enters one of the columnar activated carbon 14 for further filtration, adsorbing harmful substances in the exhaust gas. When the columnar activated carbon 14 needs to be replaced, the box cover 15 is opened, and the rotating placement seat 13 is rotated so that the bottom of the new columnar activated carbon 14 covers the top of the flow channel 12, reducing the waiting time for disassembly and installation. All columnar activated carbon 14 are replaced at the same time after they have become ineffective.

[0029] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
