Description

Technical Field

[0001] This invention relates to the field of baghouse dust collector technology, specifically a baghouse dust collector for treating exhaust gas from medical waste incineration. Background Technology

[0002] Air pollution control and treatment are crucial aspects of environmental protection, aiming to reduce pollutant emissions, ensure air quality, and ultimately protect ecosystems and public health. The treatment of exhaust gases from medical waste incineration is a significant issue in both environmental protection and public health. With the increasing volume of medical waste in modern cities, effectively reducing the impact of harmful emissions during incineration on air quality has become a common challenge for countries worldwide. The exhaust gases emitted during incineration may contain various harmful substances, such as heavy metals, dioxins, hydrogen chloride, and sulfur dioxide. These substances not only harm human health but also pollute the surrounding environment.

[0003] Chinese Patent CN104785027B, authorized and published on August 24, 2016, discloses a baghouse dust collector, which includes a dust collector housing. The dust collector housing has an air outlet on one side of its upper end and an air inlet on one side of its lower end. The dust collector housing contains a dust collection cavity. The lower half of the dust collection cavity has a dust hopper, and the upper half of the dust collection cavity has a dust collection bag. The dust hopper is open at both ends. The dust hopper contains a sedimentation cavity with a smaller upper section and a larger lower section, an expansion cavity with a larger upper section and a smaller lower section, and a discharge cavity with a larger upper section and a smaller lower section. The sedimentation cavity is located at the lower end of the expansion cavity, and the discharge cavity is located at the lower end of the sedimentation cavity.

[0004] In the aforementioned application documents, dust collector bags are used for dust removal. However, when the dust collector bags are used for dust removal, the dust collector bags closer to the inlet pipe have more contact with and process the exhaust gas, while the dust collector bags farther from the inlet pipe have lower efficiency in processing the exhaust gas, thus affecting the overall efficiency of the dust collector bags in processing the exhaust gas.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1, please refer to Figures 1-4 A bag filter for treating exhaust gas from medical waste incineration, comprising: The dust collector body 100 is equipped with an air inlet pipe 200 and an exhaust pipe 300 on both sides of the dust collector body 100, respectively. Dust collector bag 400 is installed inside the dust collector body 100 and connected to the air pump. Dust collector body 100 is equipped with a dust discharge pipe 500 at the bottom. A fixed chamber 601 is fitted at the bottom of the air inlet pipe 200. A telescopic partition 612 is fitted inside the dust collector body 100. A transmission component for transmission is fitted between the fixed chamber 601 and the telescopic partition 612. The transmission component includes a fan 602 rotatably connected inside the fixed chamber 601. A power rod 603 is fixedly connected to the side of the fan 602, and a bevel gear 604 is fixedly connected to the side of the power rod 603. Exhaust gas is input into the dust collector body 100 through the air inlet pipe 200. The exhaust gas is processed by the dust collector bag 400 inside the dust collector body 100 and then discharged through the exhaust pipe 300. The rapidly flowing exhaust gas drives the fan 602, which is rotatably connected to the fixed chamber 601, to rotate. The fan 602 then drives the power rod 603, which is fixedly connected to it, to rotate, causing the power rod 603 to drive the bevel gear 604, which is fixedly connected to it, to rotate.

[0022] A through transmission rod 605 is rotatably connected to the side of the dust collector body 100. A bevel gear 606 is fixedly connected to the side of the transmission rod 605. The bevel gear 606 is located on the side of the bevel gear 604 and is meshed with the bevel gear 604. A sprocket 607 is fixedly connected to the outside of the transmission rod 605. A chain 608 is mounted on the outside of the sprocket 607. A through reciprocating screw 609 is rotatably connected inside the dust collector body 100. A sprocket 610 is fixedly connected to the outside of the reciprocating screw 609. The end of the chain 608 away from the sprocket 607 is mounted on the outside of the sprocket 610. When bevel gear 604 rotates, it drives bevel gear 606, which meshes with it, to rotate. This causes bevel gear 606 to drive transmission rod 605, which is fixedly connected to it, to rotate. Transmission rod 605 then drives sprocket 607, which is fixedly connected to it, to rotate. In conjunction with chain 608 mounted on the outside of sprocket 607, sprocket 610, which is connected to sprocket 607 via chain 608, rotates. Sprocket 610 then drives reciprocating screw 609, which is fixedly connected to it, to rotate.

[0023] A sliding seat 611 is threadedly connected to the outer side of the reciprocating screw 609. When the reciprocating screw 609 rotates, the sliding seat 611, threadedly mounted on the outer side of the reciprocating screw 609, is simultaneously restricted by the dust collector body 100 with which it is slidably connected. This allows the reciprocating screw 609 to drive the sliding seat 611 to reciprocate horizontally. The sliding seat 611 then drives the telescopic end of the telescopic partition 612 to move, pulling it out of the telescopic partition 612, thereby intermittently changing the overall length of the telescopic partition 612. In this way, exhaust gas can also be guided to the dust collector bag 400 on the side away from the inlet pipe 200, and the dust collector bag 400 inside the dust collector body 100 can be fully utilized, improving the overall exhaust gas treatment efficiency of the dust collector bag 400.

[0024] In operation, exhaust gas is introduced into the dust collector body 100 through the inlet pipe 200. The exhaust gas is processed by the dust collector bags 400 inside the dust collector body 100 and then discharged through the exhaust pipe 300. The rapidly flowing exhaust gas drives the impeller 602, which is rotatably connected to the fixed chamber 601, to rotate. The impeller 602 then drives the power rod 603, which is fixedly connected to it, to rotate. This causes the power rod 603 to drive the bevel gear 604, which is fixedly connected to it, to rotate. The bevel gear 604 then drives the bevel gear 606, which meshes with it, to rotate. This causes the bevel gear 606 to drive the transmission rod 605, which is fixedly connected to it, to rotate. The transmission rod 605 then drives the sprocket 605, which is fixedly connected to it, to rotate. When 07 rotates, the chain 608 mounted on the outside of sprocket 607 rotates, causing sprocket 610, which is connected to sprocket 607 via chain 608, to rotate. Sprocket 610 then drives the reciprocating screw 609, which is fixedly connected to it, to rotate. Meanwhile, the sliding seat 611, which is threaded onto the outside of the reciprocating screw 609, is restricted by the dust collector body 100, which is slidably connected to it. This allows the reciprocating screw 609 to drive the sliding seat 611 to move back and forth in the horizontal direction when it rotates. The sliding seat 611 then drives the telescopic end of the telescopic partition 612 to move, pulling it out of the telescopic partition 612, thereby intermittently changing the overall length of the telescopic partition 612.

[0025] Example 2, please refer to Figures 1-6Based on Embodiment 1, the dust collector body 100 is equipped with a flow guiding component 700 for guiding exhaust gas. The flow guiding component 700 includes an elastic cam 701 fixed to the outside of the power rod 603. A through hydraulic chamber 702 is installed on the side of the dust collector body 100. One end of the hydraulic chamber 702 is slidably connected to a force rod 703 by a piston. The force rod 703 is located at the bottom of the elastic cam 701 and is in contact with the elastic cam 701. When exhaust gas is introduced, the power rod 603 is in a rotating state, which can drive the elastic cam 701 fixedly connected to it to rotate. When the protruding part of the elastic cam 701 rotates to the force rod 703, the protruding part of the elastic cam 701 can squeeze the force rod 703 and drive the force rod 703 to move downward. In conjunction with the hydraulic chamber 702 which is slidably connected to the force rod 703 by a piston, the force rod 703 can squeeze the oil originally stored in the hydraulic chamber 702 while moving into the hydraulic chamber 702.

[0026] The other end of the hydraulic chamber 702 is slidably connected to an arc-shaped rod 704 via a piston. A spring 705 is fitted at the bottom of the force-bearing rod 703. A rotating rod 706 is rotatably connected inside the dust collector body 100. A force-bearing plate 707 and a guide plate 708 are fixedly connected to the outside of the rotating rod 706. The force-bearing plate 707 is located on the side of the arc-shaped rod 704 and is fixed to the arc-shaped rod 704. When the oil originally stored in the hydraulic chamber 702 is squeezed, the oil flows towards the side closer to the arc-shaped rod 704, causing the arc-shaped rod 704, which is slidably connected to the hydraulic chamber 702 via a piston, to move out of the hydraulic chamber 702. The arc-shaped rod 704 then moves the force plate 707, which is fixedly connected to it, causing the force plate 707 to rotate the rotating rod 706, which is fixedly connected to it. The rotating rod 706 then rotates the guide plate 708, which is fixedly connected to it, at a certain angle. As the elastic cam 701 continues to rotate, the protruding part of the elastic cam 701 moves away from the force rod 703, and the force rod 703 loses its restraint and can be reset under the action of the spring 705. Similarly, the guide plate 708 is reset. In this way, the guide plate 708 can reciprocate at a certain angle on the side of the air inlet pipe 200, guiding the input exhaust gas to the dust collector bags 400 at both ends. In this way, the dust collection bags 400 inside the dust collector body 100 can be fully utilized for corresponding dust collection operations, thereby further improving its processing efficiency.

[0027] In use, based on Embodiment 1, with exhaust gas introduced, the power rod 603 is in a rotating state. The power rod 603 can drive the elastic cam 701 fixedly connected to it to rotate. When the protruding part of the elastic cam 701 rotates to the force rod 703, the protruding part of the elastic cam 701 can squeeze the force rod 703 and drive the force rod 703 to move downward. In conjunction with the hydraulic chamber 702 which is slidably connected to the force rod 703 by a piston, the force rod 703 can squeeze the oil originally stored in the hydraulic chamber 702 while moving into the hydraulic chamber 702. The oil is squeezed and flows towards the side closer to the arc-shaped rod 704, driving the piston slidably connected to the hydraulic chamber 702. The arc-shaped rod 704 moves out of the hydraulic chamber 702, and then drives the force plate 707 fixedly connected to it to move, so that the force plate 707 drives the rotating rod 706 fixedly connected to it to rotate, and the rotating rod 706 drives the guide plate 708 fixedly connected to it to rotate at a certain angle. As the elastic cam 701 continues to rotate, the protruding part of the elastic cam 701 can move away from the force rod 703, and the force rod 703 will then lose its restriction and can be reset under the action of the spring 705. Similarly, the guide plate 708 is reset. In this way, the guide plate 708 can reciprocate at a certain angle on the side of the air inlet pipe 200, and guide the input exhaust gas to the dust collector bags 400 at both ends.

[0028] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, a closing assembly 800 is installed between the air inlet pipe 200 and the ash discharge pipe 500. The closing assembly 800 includes an electric rotating rod 801 that passes through the ash discharge pipe 500, and a block 802 is fixedly connected to the bottom of the electric rotating rod 801. When a large amount of dust adheres to the outer surface of the dust collector bag 400, making it difficult to continue treating the exhaust gas, the electric rotating rod 801 and the air pump are activated. The air pump delivers air from the inside of the dust collector bag 400 to the outside, thereby blowing off a large amount of dust on the outer surface of the dust collector bag 400. Meanwhile, the electric rotating rod 801 drives the block 802, which is fixedly connected to it, to rotate, turning the ash discharge pipe 500, which was originally closed by the block 802, into an open state, and performing the corresponding ash discharge operation.

[0029] A bevel gear 803 is fixedly connected to the top of the electric rotary rod 801. A transmission rod 804 is rotatably connected to the top of the ash discharge pipe 500. A bevel gear 805 is fixedly connected to the side of the transmission rod 804. The bevel gear 805 is located on the side of the bevel gear 803 and is meshed with the bevel gear 803. A sprocket 806 is fixedly connected to the outside of the transmission rod 804. A chain 807 is mounted on the outside of the sprocket 806. A through transmission rod 808 is rotatably connected inside the air intake pipe 200. A sprocket 809 is fixedly connected to the outside of the transmission rod 808. The end of the chain 807 away from the sprocket 806 is mounted on the outside of the sprocket 809. A block 810 is fixedly connected to the side of the transmission rod 808. During the ash removal operation, the electric rotary rod 801 drives the bevel gear 3 803, which is fixedly connected to it, to rotate. This causes the bevel gear 3 803 to drive the bevel gear 4 805, which in turn drives the transmission rod 2 804, which is fixedly connected to it, to rotate. The transmission rod 2 804 then drives the sprocket 3 806, which is fixedly connected to it, to rotate. This, in conjunction with the chain 2 807 mounted on the outside of the sprocket 3 806, causes the sprocket 4 809, which is connected to the sprocket 3 806 via the chain 2 807, to rotate. The sprocket 4 809 then drives the transmission rod 3 808, which is fixedly connected to it, to rotate. This causes the block 2 810, which is fixedly connected to it, to rotate, changing the previously open air inlet pipe 200 to a closed state by the block 2 810. In this way, dust is prevented from flowing back into the air inlet pipe 200 under these conditions, ensuring it does not flow into the dust collector body 100 during subsequent processing operations, thus improving the device's processing efficiency.

[0030] In use, based on Embodiments 1 and 2, when a large amount of dust adheres to the outer surface of the dust collector bag 400, making it difficult to continue treating the exhaust gas, the electric rotating rod 801 and the air pump are activated. The air pump delivers air from the inside of the dust collector bag 400 to the outside, thereby blowing off a large amount of dust on the outer surface of the dust collector bag 400. Meanwhile, the electric rotating rod 801 drives the fixedly connected block 802 to rotate, opening the ash discharge pipe 500 that was originally closed by the block 802, performing the corresponding ash discharge operation. Simultaneously, the electric rotating rod 801 drives the fixedly connected bevel gear 803 to rotate, causing the bevel gear 803 to... The bevel gear 805 meshing with it rotates, which in turn drives the transmission rod 804 fixedly connected to it to rotate. This causes the transmission rod 804 to drive the sprocket 806 fixedly connected to it to rotate. In conjunction with the chain 807 mounted on the outside of the sprocket 806, the sprocket 809 connected to the sprocket 806 via the chain 807 rotates. The sprocket 809 then drives the transmission rod 808 fixedly connected to it to rotate, which in turn drives the block 810 fixedly connected to it to rotate, thus changing the air intake pipe 200 from an open state to a closed state by the block 810.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
