Description

Technical Field

[0001] This utility model relates to a dust collection device at the furnace door, and more particularly to a flue gas purification device for a waste incinerator, belonging to the field of flue gas purification technology. Background Technology

[0002] Waste incineration, as a highly efficient waste treatment method, is widely used in municipal waste management because it can significantly reduce the volume and weight of waste while simultaneously recovering energy. However, the incineration process generates a large amount of harmful flue gas, including particulate matter, acidic gases (such as sulfur dioxide and hydrogen chloride), nitrogen oxides, heavy metals, and organic pollutants such as dioxins. If these flue gases are emitted directly without treatment, they will cause serious harm to the environment and human health. During the operation of a waste incinerator, waste needs to be continuously fed into the furnace. During this process, the furnace door is often open, leading to flue gas leakage. This leakage not only pollutes the operating environment and reduces air quality but also threatens the health of operators. Furthermore, flue gas leakage reduces the efficiency of the entire flue gas purification system and increases the burden on subsequent purification equipment. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a flue gas purification device for waste incinerators. By setting a dust suction hood outside the furnace door and combining it with a high-temperature resistant dustproof cloth and an adjustable door frame structure, the device effectively prevents flue gas from overflowing from the furnace door and improves the integration and operating efficiency of the entire flue gas purification system.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A flue gas purification device for a waste incinerator includes an incinerator body, a first exhaust duct, and an incinerator door. The top of the incinerator body is connected to the first exhaust duct via a first fan. An incinerator door is provided on one side of the incinerator body. A dust collection hood is provided outside the incinerator door. The top of the dust collection hood is connected to a second exhaust duct via a second fan. Baffles are provided on both sides of the right side of the dust collection hood, and a gate-shaped frame is provided between the two side baffles. There are at least three gate-shaped frames, and a high-temperature resistant dustproof cloth is provided between adjacent gate-shaped frames. Rollers are provided at the bottom of the gate-shaped frames.

[0005] The left side of the dust collection hood is fixedly connected to the incinerator body, and the inner wall of the dust collection hood is provided with a filter screen.

[0006] A strip track is provided in the middle of the inner wall of the baffle, and the outer wall of the portal frame is slidably connected to the strip track by a slider.

[0007] A high-temperature resistant dustproof cloth is installed between the door frame and the dust collection hood.

[0008] The high-temperature resistant dustproof cloth on the side of the portal frame is located inside the baffle, and the bottom of the high-temperature resistant dustproof cloth is located above the strip track.

[0009] The positive and beneficial effects of this utility model are: 1. This utility model, by installing a dust-collecting hood on the outside of the furnace door, in conjunction with the use of a door frame and a high-temperature resistant dustproof cloth, can effectively collect and block the flue gas leaking from the furnace door, prevent it from overflowing into the operating environment, significantly reduce the amount of flue gas leaking from the furnace door, reduce the impact on the health of operators, and improve the operating environment.

[0010] 2. This utility model facilitates the collection and management of the portal frame by sliding it together with the baffle. When the waste incinerator is not in operation, the operator can easily slide all the portal frames and the high-temperature dustproof cloth between them along the track and collect them to one side, which facilitates the unified management and maintenance of the equipment by the staff. This effectively avoids these components occupying too much space when idle, thereby further improving the adaptability and flexibility of the equipment.

[0011] 3. By setting a filter screen on the inner wall of the dust collection hood, this utility model can further filter particulate matter in the flue gas entering the dust collection hood, reduce the burden on the subsequent purification system, improve the pretreatment effect of the flue gas, and extend the service life of the subsequent purification equipment.

Detailed Implementation

[0013] The present invention will be further explained and described below with reference to the accompanying drawings: See the example. Figures 1-3A flue gas purification device for a waste incinerator includes an incinerator body 1, a first exhaust duct 2, and an incinerator door 3. The first exhaust duct 2 is connected to the top of the incinerator body 1 via a first fan. The incinerator door 3 is provided on one side of the incinerator body 1. A dust collection hood 4 is provided outside the incinerator door 3. A second exhaust duct 6 is connected to the top of the dust collection hood 4 via a second fan. Baffles 7 are provided on both sides of the right side of the dust collection hood 4, and a gate-shaped frame 9 is provided between the two side baffles 7. There are at least three gate-shaped frames 9, and a high-temperature resistant dustproof cloth 11 is provided between adjacent gate-shaped frames 9. Rollers 10 are provided at the bottom of the gate-shaped frames 9.

[0014] In the above description, the dimensions of the side of the dust hood are larger than the dimensions of the furnace door.

[0015] The left side of the dust hood 4 is fixedly connected to the incinerator body 1, and a filter screen 5 is provided on the inner wall of the dust hood 4.

[0016] In the above description, the dust hood has a hollow structure inside, with through holes cut into the inner wall of the dust hood, and a filter screen is installed at the through holes by bolts.

[0017] A strip track 8 is provided in the middle of the inner wall of the baffle 7, and the outer wall of the portal frame 9 is slidably connected to the strip track 8 by a slider.

[0018] A high-temperature resistant dustproof cloth 11 is provided between the door frame 9 and the dust hood 4.

[0019] In the above description, the bottom of the high-temperature resistant dustproof cloth on the side is located below the top of the baffle.

[0020] The high-temperature resistant dustproof cloth 11 on the side of the door frame 9 is located inside the baffle 7, and the bottom of the high-temperature resistant dustproof cloth 11 is located above the strip track 8.

[0021] In the above description, the high-temperature resistant dustproof cloth is not fixed to the baffle. When the incinerator is not in use, all the door frames are retracted together, and at the same time, the high-temperature resistant dustproof cloth is also retracted together.

[0022] In the above description, the portal frame and the baffle are fixed together with bolts. During construction, bolt holes are drilled at the positions of the baffle and the corresponding portal frame for bolt installation.

[0023] In the above description, there are two baffles, which are fixedly connected to the right side of the dust hood by bolts.

[0026] In the above description, rollers are provided at both ends of the bottom of the portal frame, and the rollers are located on the ground.

[0027] Working principle: When feeding materials, open the portal frame in sequence and fix the portal frame to the baffle with bolts. Then turn on the second blower and open the furnace door to feed materials into the incinerator. When the incinerator is not in use, loosen the bolts used to fix the portal frame and retract the portal frame together.

[0028] This invention effectively collects and blocks leaking flue gas at the furnace door by installing a dust-collecting hood on the outside of the furnace door, in conjunction with a door frame and a high-temperature resistant dustproof cloth, significantly reducing the amount of flue gas leaking at the furnace door and improving the workshop environment.
