Description

Technical Field

[0001] The utility model relates to the technical field of smoke dust treatment, in particular to a smoke dust removal device capable of recovering waste heat from a biomass boiler. Background Art

[0002] Biomass boilers are widely used in production and life. Existing biomass boilers, especially small and medium-sized biomass boilers, mostly directly discharge their flue gas into the atmosphere. The dust and sulfur oxides in the flue gas will cause serious pollution to the environment. In addition, the flue gas discharged from the biomass boiler also carries a large amount of waste heat, which is generally 200-300℃, resulting in energy loss and reduced fuel thermal efficiency, which not only pollutes the environment but also increases production costs.

[0003] After searching, Chinese patent announcement number: CN208642175U discloses a flue gas dust removal device that can recover waste heat from a biomass boiler, including a waste heat recovery tower and a spray dust removal tower, the waste heat recovery tower includes a tower body, a first flue gas inlet is provided at the lower end of the tower body, and a first flue gas outlet is provided at the upper end of the tower body, and a plurality of heat exchange devices are provided inside the tower body, and the heat exchange device includes a shell, a heat exchange coil and a fixed plate, the shell is U-shaped, and the shell is transversely arranged on the tower body, a rectangular outlet is provided on one side of the shell, the fixed plate is located outside the rectangular outlet, and the fixed plate and the shell are fixedly connected by screws, the heat exchange coil is located inside the shell, and the water outlet and water inlet of the heat exchange coil are fixed on the fixed plate, and the spray dust removal tower is located on one side of the waste heat recovery tower. Compared with the traditional flue gas dust removal device for recovering waste heat from biomass boilers, the utility model is easy to disassemble and assemble, simple to maintain, and has better treatment effect. The above-mentioned lack of dust removal on the inner wall of the boiler leads to an increase in dust on the inner wall of the boiler device, which reduces the usability and life of the device. In addition, the lack of dust prevention will cause these particles to be directly discharged into the atmosphere, aggravating the air pollution problem and causing negative impacts on the surrounding environment. Therefore, a flue gas dust removal device that can recover the waste heat of a biomass boiler is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a flue gas dust removal device which can recover the waste heat of a biomass boiler, aiming to improve the existing technology of dust removal on the inner wall of the boiler through a dust removal mechanism, so as not to increase the dust on the inner wall of the boiler device and reduce the usability and life of the device. The dust prevention mechanism can effectively capture and remove the particulate matter and dust generated by biomass combustion, thereby reducing the amount of particulate matter emitted by the boiler, reducing air pollution and protecting the surrounding environment.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a flue gas dust removal device that can recover the waste heat of a biomass boiler, including a boiler, a top side of the boiler is slidably connected to an electric telescopic rod, the top of the electric telescopic rod is rotatably connected to a motor, the driving end of the electric telescopic rod is fixedly connected to a connecting rod, the upper and lower peripheries of the connecting rod are fixedly connected to a cleaning rack, the interior of the cleaning rack is slidably connected to sliding plates, the two sliding plates are fixedly connected to a brush on the separated sides, two telescopic springs are fixedly connected to the front end of the right side of the sliding plate, the lower left side of the boiler is fixedly connected to a flue gas inlet, the upper right side of the boiler is fixedly connected to a flue gas outlet, and a fixed component is provided on one side of the flue gas outlet.

[0006] Furthermore, the fixing assembly includes multiple fixing blocks, each of which is fixedly connected to both ends of the smoke outlet, each of which is slidably connected to an insertion rod on the inner side, each of which is fixedly connected to a spring 2 at the other end, and each of which is provided with a dustproof assembly at the other end.

[0007] Furthermore, the dustproof assembly includes a dustproof frame, the dustproof frame is fixedly connected to one side of the second spring, and a dustproof net is fixedly connected to the inner side of the dustproof frame.

[0008] Furthermore, a dust exhaust port is fixedly connected to the bottom of the boiler, and a worm is threadedly connected to one side of the dust exhaust port.

[0009] Furthermore, one end of the worm is fixedly connected to a rotating handle.

[0010] Furthermore, the other end of the worm is fixedly connected with an opening and closing plate.

[0011] Furthermore, a collection box is slidably connected to the bottom of the dust exhaust port.

[0012] Furthermore, a plurality of support seats are fixedly connected to the bottom end of the boiler.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the electric drive causes the electric telescopic rod to rotate, the rotating electric telescopic rod drives the connecting rod to rotate, and the rotating connecting rod drives the cleaning rack to rotate on the inner wall of the boiler. At this time, the cleaning rack on the connecting rod generates a telescopic force through an internal spring when rotating, so that the brush on the sliding plate cleans the inner wall of the boiler evenly, and then the electric telescopic rod can be started to change the height of the cleaning rack, so as to better clean the dust on the inner wall of the boiler. The dust removal of the inner wall of the boiler is achieved in the above manner, so that the dust on the inner wall of the boiler device will not increase, which will reduce the usability and life of the device.

[0015] 2. In the utility model, both the flue gas inlet and the flue gas outlet are provided with dust-proof mechanisms, and the dust-proof net can prevent dust when the flue gas enters and exits. When the dust-proof net needs to be taken down for cleaning due to excessive dust, the plug rods on both sides of the dust-proof frame are pressed, so that the two springs generate a telescopic force through the pressing force to disengage the two plug rods from the two through holes on the two fixed blocks, thereby removing the dust-proof frame stuck in the flue gas inlet or the flue gas outlet, and the dust-proof frame is removed together with the dust-proof net. Through the above, it is achieved that the particulate matter and dust generated by biomass combustion can be effectively captured and removed, thereby reducing the amount of particulate matter emitted by the boiler, reducing air pollution, and protecting the surrounding environment.
