Description

Technical Field

[0001] This invention relates to the field of sintered plate dust collector technology, and in particular to a tail gas treatment system for sintered plate dust collectors. Background Technology

[0002] Sintered plate dust collectors, also known as sintered plate filters or plastic sintered plate dust collectors, are high-efficiency dust removal devices that primarily rely on gas filtration to remove dust. Their working principle involves guiding dust-laden gas into the dust chamber via a guide plate, and then purifying the gas using the sintered plate as the core filter element.

[0003] While sintered plate dust collectors perform excellently in dust removal, they are ineffective at filtering harmful gaseous components in high-temperature dust gases, such as harmful heavy metal compounds, sulfides, nitrogen oxides, and potentially metal vapors, when used in boiler rooms or smelting plants. These untreated emissions not only threaten the environment but may also harm human health. Furthermore, from the perspective of environmental sustainability and a circular economy, developing and applying advanced exhaust gas recovery and purification technologies can not only reduce environmental impact but also achieve the recovery of valuable metal resources, promoting harmonious economic and environmental development. Therefore, further recovery and purification of the exhaust gas from sintered plate dust collectors is particularly important. Summary of the Invention

Detailed Implementation

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0037] Example 1

[0038] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a tail gas treatment system for a sintered plate dust collector, which includes a flow unit 100, including an inlet pipe 101, a cooling pipe 102 disposed outside the inlet pipe 101, a conical pipe 103 disposed on one side of the inlet pipe 101, and an outlet pipe 104 disposed inside the conical pipe 103.

[0039] The processing unit 200 includes a fan ring 201 disposed on the top of the inner side of the conical tube 103, multiple sets of adsorption elements 202 disposed on the bottom periphery of the fan ring 201, a swinging element 203 disposed on the bottom of the adsorption element 202, a filter element 204 disposed on the bottom of the air outlet tube 104, and a sealing element 205 disposed on the bottom of the swinging element 203.

[0040] It should be noted that, as Figure 1 As shown, the inlet pipe 101 is connected to the outlet pipe of the sintered plate dust collector. High-temperature dusty gas enters the circulation unit 100 after being filtered by the sintered plate dust collector, and is then discharged after being treated by the treatment unit 200. The outer wall of the inlet pipe 101 is carefully wrapped with a cooling pipe 102 from the circulating cooling system. The coolant flowing inside the cooling pipe 102 not only provides an effective cooling path for the high-temperature exhaust gas, but also causes the metal vapor generated at high temperatures to condense into metal particles during the cooling process. This change greatly improves the capture rate of metal particles, laying the foundation for subsequent recovery work and creating more favorable conditions for further treatment of the exhaust gas.

[0041] Preferably, a set of conical tubes 103 are connected to the rear end of the intake pipe 101. The conical tubes 103 consist of an upper cylinder and a lower cone, forming a unique structure. The intake pipe 101 is connected to the upper part of the cylinder of the conical tubes 103, providing a smooth passage for the exhaust gas to enter. After the exhaust gas enters the conical tubes 103, it flows downwards in a spiral along a predetermined path. The rotational motion of the gas enhances the centrifugal force, centrifugally separating the components in the exhaust gas, facilitating subsequent treatment by the processing unit 200.

[0042] Preferably, a set of fan rings 201 are hinged at the center of the conical tube 103 on one side of the intake pipe 101. The fan rings 201 can rotate under the thrust of the exhaust gas. The rotation of the fan rings 201 can drive the swing member 203 below to rotate, and the swing member 203 is in contact with the inner wall of the conical tube 103. With the swing member 203 in contact, it can provide current to the adsorption member 202, which acts as an electromagnet to adsorb metal particles in the exhaust gas. In addition, the exhaust gas after filtering the metal enters the exhaust pipe 104, and the filter member 204 set inside the exhaust pipe 104 performs the final purification filtration of the exhaust gas.

[0043] In summary, with the arrangement of the flow unit 100 and the processing unit 200, this device achieves automatic opening and closing of the electromagnet using the flow of exhaust gas, effectively adsorbing metal particles in the exhaust gas, improving the efficiency of metal recovery, and contributing to resource recycling. It reduces manual operation and increases the system's automation level. Furthermore, when energized, closing the collection port of the conical tube 103 ensures unidirectional flow of exhaust gas into the outlet pipe, followed by purification treatment by the decomposition liquid 204c, reducing the emission of harmful substances. When de-energized, opening the collection port of the conical tube 103 facilitates the collection of metal particles by personnel at the conical opening of the tube 103.

[0044] Example 2

[0045] Reference Figures 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that: this embodiment further provides a tail gas treatment system for a sintering plate dust collector, which includes a fan ring 201 facing the side of the inlet pipe 101;

[0046] The fan ring 201 includes a conductor coil 201a disposed inside it, a sleeve 201b disposed inside the conductor coil 201a, and a rotating rod 201c disposed inside the sleeve 201b.

[0047] Furthermore, the coil 201a includes a connecting wire 201a-1 extending on the outer side of the top of the tapered tube 103, a conductive ring 201a-2 fixedly disposed on the inner side of the fan ring 201, and a conductive plate 201a-3 electrically connected to the winding copper 202c.

[0048] The connecting line 201a-1 includes a copper ring 201a-11 that passes through the top of the conical tube 103; the copper ring 201a-11 is slidably connected to the conductive ring 201a-2.

[0049] It should be noted that, as Figure 2 and Figure 4As shown, a set of fan rings 201 are hinged to the top of the conical tube 103 on the side opposite to the intake pipe 101. The size of the fan rings 201 is smaller than that of the intake pipe 101 so that the fan rings 201 can be effectively rotated by the exhaust gas without obstructing the downward spiral flow of the exhaust gas. In addition, the fan rings 201 have a special structure, with a set of conductive coils 201a arranged inside the fan rings 201. The conductive coils 201a are connected by a conductive ring 201a-2 fixedly connected to the inside of the fan rings 201, a connecting line 201a-1 slidably connected to the upper side of the conductive ring 201a-2, and a conductive plate 201a-3 fixedly connected to the bottom of the conductive ring 201a-2. The connecting line 201a-1 is embedded through the top of the conical tube 103, wherein a copper ring 201a-11 is embedded in the top of the conical tube 103 and slidably connected to the conductive ring 201a-2 below. The connecting line 201a-1, extending from the copper ring 201a-11 to the outside of the tapered tube 103, is connected to the positive terminal of the power supply. Furthermore, a set of sleeves 201b is fixedly connected to the inner side of the coil 201a, and a rotating rod 201c is fixedly connected downwards to the circumference of the sleeves 201b. When the fan ring 201 rotates, it can drive the sleeves 201b and the inner rotating rod 201c to rotate.

[0050] Furthermore, the adsorption component 202 includes multiple sets of I-shaped blocks 202a disposed on the bottom periphery of the fan ring 201, a connecting pipe 202b disposed on the inner side of the I-shaped blocks 202a, a winding copper 202c disposed on the periphery of each set of I-shaped blocks, and a connecting disk 202d disposed on the bottom of the I-shaped blocks 202a.

[0051] The connecting disc 202d and the winding copper 202c are an integral structure and are electrically connected.

[0052] It should be noted that, as Figure 2 and Figure 5 As shown, a set of connecting pipes 202b are arranged around the vent pipe 104 located inside the conical tube 103. Multiple sets of I-shaped blocks 202a are fixedly connected to the outer periphery of the connecting pipes 202b. Copper wire 202c is wound around the grooves of the I-shaped blocks 202a. The upper part of the copper wire 202c is slidably connected to the conductive plate 201a-3, while the lower part is fixedly connected to the connecting disk 202d. The connecting disk 202d and the conductive plate 201a-3 are made of the same material and have the same shape, so that when the fan ring 201 rotates, driving the oscillating member 203 to rotate, it can always maintain an electrical connection with the copper wire 202c.

[0053] Preferably, the I-shaped block 202a can be made of iron. When the wound copper 202c is energized, the I-shaped block 202a under the wound copper 202c becomes a magnetic electromagnet. The range and strength of the magnetic force can be adjusted according to actual needs. As the exhaust gas enters the inner side of the conical tube 103, in a specific area inside the conical tube, the exhaust gas is subjected to centrifugal force, begins to rotate, and accelerates downward. This high-speed rotating airflow not only promotes the contact between the gas and the tube wall, but also greatly increases the probability of collision between metal particles and the adsorption surface M. Under the action of the electromagnet, the adsorption surface M becomes a highly efficient metal collection area. Under the dual action of centrifugal force and magnetic force, the metal gas adheres more effectively to the adsorption surface M. This process not only improves the efficiency of metal recovery, but also helps to further purify the exhaust gas, ensuring that the emitted gas meets environmental protection standards.

[0054] Furthermore, the swing member 203 includes a rotating disk 203a disposed on the outside of the rotating rod 201c, two sets of swing rods 203b disposed on both sides of the rotating disk 203a, a gravity ball 203c disposed on one side of the swing rod 203b, and a connecting ring 203d embedded in the side wall of the conical tube 103.

[0055] All swing components 203 are made of conductive material and slide and are electrically connected to the connecting plate 202d.

[0056] Furthermore, the swing arm 203b includes an L-shaped guide rod 203b-1 disposed on one side of the gravity ball 203c, and an arc-shaped rod 203b-2 fixedly disposed on one side of the L-shaped guide rod 203b-1.

[0057] Furthermore, the rotating disk 203a includes multiple sets of conductive strips 203a-1 overlapping the periphery of the connecting disk 202d, and a conductive disk 203a-2 disposed at the bottom of the conductive strips 203a-1;

[0058] L-shaped guide rod 203b-1 includes a hinge shaft 203b-11 disposed at its corner;

[0059] The arc-shaped rod 203b-2 includes a connecting shaft 203b-21 disposed at its end.

[0060] Furthermore, the hinge shaft 203b-11 is hinged to the conductive disk 203a-2;

[0061] The connecting shaft 203b-21 is hinged to the connecting rod 205a.

[0062] It should be noted that, as Figure 2 and Figure 5As shown, a set of rotating disks 203a are radially limited at the bottom of the rotating rod 201c. The rotating disks 203a consist of multiple sets of conductive strips 203a-1 overlapping the periphery of the connecting disk 202d, and conductive disks 203a-2 at the bottom of the conductive strips 203a-1. Conductive hinge holes are provided on the periphery of the conductive disks 203a-2. A set of swing rods 203b are hinged to these hinge holes. The swing rods 203b consist of an arc-shaped rod 203b-2 on one side of the hinge hole and an L-shaped guide rod 203b-1 on the other side of the hinge hole. A set of hinge shafts 203b-11 are provided at the corner point of the L-shaped guide rods 203b-1, and the hinge shafts 203b-11 are hinged to the conductive hinge holes on the periphery of the conductive disks 203a-2.

[0063] Preferably, a set of gravity balls 203c are fixedly connected to one outer end of the L-shaped guide rod 203b-1, and the gravity balls 203c have a certain gravity. When the rotating rod 201c drives the rotating disk 203a, the gravity balls 203c pull the L-shaped guide rod 203b-1 and the arc-shaped rod 203b-2 to rotate, causing the originally sunken L-shaped guide rod 203b-1 to move upward under the rotation of the gravity balls 203c, while the arc-shaped rod 203b-2 on the other side of the hinge shaft 203b-11 moves downward. Furthermore, the arc-shaped rod 203b-2 has a certain arc plate, which facilitates the downward movement of the arc-shaped rod 203b-2 without obstructing the movement of the rotating rod 201c. The gravity balls 203c can fit against the inner side of the connecting ring 203d during rotation.

[0064] Preferably, embedded wires are provided on the inner side of the L-shaped guide rod 203b-1 and the inner side of the gravity ball 203c, and the connecting ring 203d is made of conductive material. When rotated, the wires inside the gravity ball 203c slide with the connecting ring 203d and maintain power connection, while one side of the connecting ring 203d is connected to the negative terminal of the power supply.

[0065] Preferably, as the gravity ball 203c rotates, it moves upward under the hinge of the L-shaped guide rod 203b-1 and the rotating disk 203a, causing one side of the gravity ball 203c to slide and rotate in connection with the connecting ring 203d. This energizes the previously short-circuited and unconnected adsorption component 202, forming an electromagnet for adsorption. Furthermore, when the gravity ball 203c contacts the inner wall of the conical tube 103, it not only energizes the adsorption component 202 but also provides a rotating and vibrating effect on the inner wall of the conical tube 103, effectively dislodging particles adhering to the inner wall of the conical tube 103.

[0066] Furthermore, the sealing component 205 includes a connecting rod 205a disposed on one side of each set of swing rods 203b, a sealing block 205b disposed at the bottom of the connecting rod 205a, and a limiting rod 205c disposed inside the sealing block;

[0067] The sealing block 205b mates with the conical opening of the conical tube 103.

[0068] Furthermore, the filter element 204 includes a cavity 204a disposed outside the rotating rod 201c, a rubber sheet 204b disposed at the bottom of the cavity 204a, and a decomposition liquid 204c disposed inside the cavity.

[0069] The lever 201c includes multiple sets of paddles 201c-1 disposed on the periphery.

[0070] It should be noted that, as Figure 2 and Figure 3 As shown, when the exhaust gas rotates and rises in the gravity ball 203c, the L-shaped guide rod 203b-1 deflects, while the arc-shaped rod 203b-2 on one side moves downward. A connecting rod 205a is hinged to one end of the arc-shaped rod 203b-2, and a sealing block 205b is hinged to the other end of the connecting rod 205a. The sealing block 205b is hollow inside, and a limiting rod 205c is slidably connected to its inner side. This limiting rod 205c is slidably connected to the rotating rod 201c. When the arc-shaped rod 203b-2 moves downward, it causes the connecting rod 205a to drive the sealing block 205b downward, sealing the conical opening of the conical tube 103. This design facilitates the adsorption of metal particles by first energizing the adsorption element 202 under the upward rotation of the gravity ball 203c, and then sealing the conical opening of the cone-shaped tube 103, finally allowing the exhaust gas to be discharged through the exhaust pipe 104. When the exhaust gas input stops, the gravity ball 203c can no longer adhere to the connecting ring 203d and slides down, causing the adsorption element 202 to be de-energized, allowing the adsorbed metal particles to fall off. At the same time, the sealing block 205b is lifted, making it easier for workers to collect the metal particles at the conical opening of the cone-shaped tube 103.

[0071] Preferably, when the exhaust gas is subjected to electrostatic adsorption by the gravity ball 203c and the cone opening of the cone tube 103 is blocked by the sealing block 205b, the exhaust gas is forced into the exhaust pipe 104. The bottom of the cavity 204a inside the exhaust pipe 104 has a tapering design, and a set of rubber sheets 204b is sleeved at the bottom of the cavity 204a. The rubber sheets 204b are attached to the opening of the cavity 204a. The decomposition liquid 204c is added into the cavity 204a above the rubber sheets 204b to purify the exhaust gas after the metal gas has been removed. In addition, multiple sets of paddles 201c-1 are installed around the rotating rod 201c. The paddles 201c-1 agitate the decomposition liquid 204c to fully mix and purify the exhaust gas.

[0072] Operating Procedure: When exhaust gas is input, it is first pre-treated through the cooling pipe 102 on the intake pipe 101. Here, the coolant circulating inside the cooling pipe rapidly cools the metallic gases in the exhaust gas, causing them to condense into particles. Subsequently, the flow of exhaust gas drives the fan ring 201 to rotate, which in turn drives the rotating rod 201c, causing it to rotate the rotating disk 203a and the gravity ball 203c together. The ingenious design of the gravity ball 203c allows it to fit against the inner side of the connecting ring 203d, automatically establishing a circuit connection between the negative and positive terminals of the power supply. At this instant, the I-shaped block 202a transforms into a powerful electromagnet under the action of the current, and its magnetic field firmly attracts the metallic particles in the exhaust gas to the adsorption surface M of the metal collection area.

[0073] Meanwhile, the arc-shaped rod 203b-2 blocks the collection port of the cone-shaped tube 103 to ensure unidirectional flow of exhaust gas, and the exhaust gas is purified by the decomposition liquid 204c in the exhaust pipe 104, ultimately achieving the emission of clean exhaust gas.

[0074] When the exhaust gas input stops, the gravity ball 203c falls under the influence of gravity, cutting off the circuit connection and causing the I-shaped block 202a to lose its magnetism. The metal particles that were originally firmly attracted begin to fall off after losing their magnetic force. At the same time, the sealing block 205b is lifted, providing a convenient collection point for the staff to collect the metal particles at the conical opening of the conical tube 103.

[0075] In summary, with the arrangement of the flow unit 100 and the processing unit 200, this device achieves automatic opening and closing of the electromagnet using the flow of exhaust gas, effectively adsorbing metal particles in the exhaust gas, improving the efficiency of metal recovery, and contributing to resource recycling. It reduces manual operation and increases the system's automation level. Furthermore, when energized, closing the collection port of the conical tube 103 ensures unidirectional flow of exhaust gas into the outlet pipe, followed by purification treatment by the decomposition liquid 204c, reducing the emission of harmful substances. When de-energized, opening the collection port of the conical tube 103 facilitates the collection of metal particles by personnel at the conical opening of the tube 103.
