[0002] Boiler flue gas refers to the flue gas produced when heated by a high-temperature heat source during industrial production. The main components of boiler flue gas include water vapor, carbon dioxide, nitrogen, oxygen, as well as carbon monoxide and soot produced by incomplete combustion.
[0003] The flue gas generated by boiler combustion contains a large amount of soot. If it is not treated and directly discharged into the atmosphere, it will pollute the air and harm the human body. In order to better address the above problems and promote the development of industry technology, this application is committed to the research and development of new technologies and proposes a new device. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a boiler flue gas recovery and dust settling mechanism.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A boiler flue gas recovery and dust settling mechanism includes a housing. An inlet pipe is fixedly connected to one side of the housing, and an outlet pipe is fixedly connected to the side of the housing away from the inlet pipe. A fixing plate is fixedly connected to the top of the housing. Multiple mounting holes are opened on the top of the fixing plate, and nozzles are fixedly connected to each of the mounting holes. A water pipe bracket is provided on the top of the fixing plate, and the water pipe bracket is fixed to the multiple nozzles. A partition is fixedly connected to the bottom of the fixing plate at the center, and the partition is fixed to the housing. A clearance opening is opened on one side of the partition near the bottom. An auxiliary flue gas flow guiding component is provided inside the housing below the partition.
[0007] As a further embodiment of this utility model, the flow guiding component includes a rotating shaft, which is rotatably connected inside the housing and located directly below the partition. Multiple evenly distributed guide plates are fixedly connected to the outer circumference of the rotating shaft. A motor is fixedly connected to one side of the outer wall of the housing, and one end of the motor output shaft passes through the housing and is fixed to the rotating shaft.
[0008] As a further embodiment of this utility model, a plurality of waste discharge pipes are fixedly connected to one side of the housing at a position directly below the smoke outlet pipe.
[0009] As a further embodiment of this utility model, a water inlet pipe is fixedly connected to the top of the housing, and the water inlet pipe passes through the housing and is fixed to the water pipe frame.
[0010] As a further embodiment of this utility model, a water outlet pipe is fixedly connected to the bottom of the shell at the center position, and a valve is provided on the outside of the water outlet pipe.
[0011] As a further embodiment of this utility model, a support bracket for supporting the shell is fixedly connected to the bottom outer wall of the shell.
[0012] As a further improvement of this invention, one side of the housing is provided with an observation window for observing the internal conditions of the housing.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. In this utility model, by setting the nozzle, the flue gas is added into the housing through the liquid inlet pipe. At this time, due to the baffle blocking the flue gas, the flue gas will flow downward. At the same time, the flue gas is sprayed through the nozzle. At this time, the water droplets will adsorb the dust in the flue gas and fall to the bottom of the housing. Then the flue gas will flow under the baffle and be discharged through the flue gas outlet pipe, thereby reducing the dust in the flue gas, preventing the flue gas from being directly emitted into the air and causing pollution, and reducing the harm to the human body.
[0015] 2. In this utility model, by setting the flow guiding component, when the liquid level in the shell exceeds the clearance port on the partition, the flue gas will enter the accumulated liquid. The flow guiding component guides the liquid, thereby guiding the flue gas in the liquid and allowing the flue gas to be discharged through the flue pipe, thus improving the performance of the dust settling mechanism.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.
[0023] Reference Figures 1-5 A boiler flue gas recovery and dust settling mechanism includes a housing 1. An inlet pipe 2 is bolted to one side of the housing 1, and an outlet pipe 3 is bolted to the side of the housing 1 away from the inlet pipe 2. A fixing plate 15 is welded to the top of the housing 1. Multiple mounting holes are provided on the top of the fixing plate 15, and nozzles 16 are bolted to each of these holes. A water pipe bracket 14 is provided on the top of the fixing plate 15 and is fixed to the multiple nozzles 16. A partition plate 12 is welded to the center of the bottom of the fixing plate 15 and is fixed to the housing 1. A clearance opening 13 is provided on one side of the partition plate 12 near the bottom. An auxiliary flue gas outlet is located inside the housing 1 below the partition plate 12. The flow guiding component, in use, introduces flue gas into the housing 1 through the inlet pipe 2. At this time, due to the obstruction of the baffle 12, the flue gas will flow downward. At the same time, water is sprayed through the nozzle 16, thus spraying water onto the flue gas entering the housing 1. The water droplets will absorb the dust in the flue gas and fall to the bottom of the housing 1, causing the dust-absorbing water droplets to accumulate at the bottom of the housing 1. When the flue gas flows to the outlet 13 and below the baffle 12, the treated flue gas will flow to the other side of the baffle 12 and be discharged from the housing 1 through the outlet pipe 3, thereby reducing dust in the flue gas, preventing the flue gas from being directly emitted into the air and causing pollution, and reducing harm to the human body.
[0024] In this utility model, the flow guiding component includes a rotating shaft 11, which is rotatably connected inside the housing 1 and located directly below the partition 12. Multiple evenly distributed guide plates 17 are welded to the outer circumference of the rotating shaft 11. A motor 9 is fixed to one side of the outer wall of the housing 1 by bolts, and one end of the output shaft of the motor 9 passes through the housing 1 and is fixed to the rotating shaft 11. Water droplets that adsorb dust accumulate at the bottom of the housing 1. When the liquid level in the housing 1 exceeds the clearance port 13 on the partition 12, the flue gas flows downward and enters the accumulated liquid. At this time, the motor 9 is started, and the motor 9 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the guide plate 17 to rotate, and the guide plate 17 causes the accumulated liquid to flow. At the same time, the flue gas that enters the liquid will flow with the liquid, thereby guiding the flue gas in the liquid and allowing the flue gas to be discharged through the smoke outlet pipe 3, thus improving the use effect of the dust settling mechanism.
[0025] In particular, multiple waste discharge pipes 10 are bolted to one side of the housing 1, directly below the exhaust pipe 3. When the liquid level inside the housing 1 reaches the waste discharge pipe 10, the liquid on the outermost surface will be discharged from the housing 1 through the waste discharge pipe 10, while dust will float on the surface of the liquid, thus causing the dust to be discharged from the housing 1 along with the liquid. A water inlet pipe 5 is bolted to the top of the housing 1, and the water inlet pipe 5 passes through the housing 1 and is fixed to the water pipe frame 14. Water is added into the water pipe frame 14 through the water inlet pipe 5, and the water entering the water pipe frame 14 will be sprayed out through the nozzle 16. A water outlet pipe 6 is bolted to the bottom of the housing 1 at the center position. The water outlet pipe 6 is used to discharge the water accumulated inside the housing 1. A valve 7 is provided on the outside of the water outlet pipe 6. A bracket 8 for supporting the housing 1 is bolted to the bottom outer wall of the housing 1. An observation window 4 for observing the internal condition of the housing 1 is provided on one side of the housing 1.
[0026] Working Principle: During operation, flue gas is introduced into the housing 1 through the inlet pipe 2. Due to the obstruction of the baffle 12, the flue gas flows downwards. Simultaneously, water is added to the water pipe rack 14 through the water inlet pipe 5. The water entering the water pipe rack 14 is sprayed out through the nozzle 16, thus spraying water onto the flue gas entering the housing 1. The water droplets absorb dust in the flue gas and fall to the bottom of the housing 1, causing the dust-absorbing water droplets to accumulate at the bottom. When the flue gas flows to the outlet 13 and below the baffle 12, the treated flue gas flows to the other side of the baffle 12 and is discharged from the housing 1 through the outlet pipe 3. This process effectively reduces dust in the flue gas, preventing direct emission into the air and causing pollution, while also reducing... With less harm to the human body, water droplets that absorb dust accumulate at the bottom of the housing 1. When the liquid level inside the housing 1 exceeds the clearance opening 13 on the partition 12, the flue gas flows downward and enters the accumulated liquid. At this time, the motor 9 is started, and the motor 9 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the guide plate 17 to rotate, and the guide plate 17 causes the accumulated liquid to flow. At the same time, the flue gas that has entered the liquid will flow with the liquid, thereby guiding the flue gas in the liquid and allowing the flue gas to be discharged through the exhaust pipe 3, which improves the effectiveness of the dust settling mechanism. When the liquid level inside the housing 1 reaches the exhaust pipe 10, the liquid on the outermost surface will be discharged from the housing 1 through the exhaust pipe 10, while the dust will float on the surface of the liquid, thus allowing the dust to be discharged from the housing 1 with the liquid.
[0027] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
