Abstract
Description
Technical Field
[0001] This invention relates to the field of flue gas purification technology, and more specifically, to a waste incineration flue gas desulfurization, denitrification, dioxin removal, and dust removal device. Background Technology
[0002] Waste incineration is an effective waste treatment method that can significantly reduce waste volume and processing capacity while recovering heat energy for power generation or heating. However, during the incineration process, a large number of harmful pollutants are generated in the flue gas, such as sulfur dioxide, nitrogen oxides, dioxins, and fine dust. These substances not only negatively impact air quality but also directly threaten public health. Sulfur dioxide is a major acidic gas that can lead to acid rain formation and damage ecosystems and water health; nitrogen oxides can cause photochemical smog and respiratory diseases; and dioxins, as a strong persistent organic pollutant, have bioaccumulation and toxicity, which can have long-term effects on biological and human health. The flue gas also contains a large amount of particulate matter, which not only affects air quality but may also harm human health after prolonged exposure. With the advancement of technology and the improvement of environmental awareness, the technology for treating pollutants from waste incineration flue gas will continue to move towards higher efficiency, lower energy consumption, and safer use, helping to optimize resource utilization during the incineration process and truly achieve green incineration.
[0003] However, existing flue gas treatment devices after waste incineration still have some problems in actual use. For example, most existing flue gas treatment devices rely on activated carbon adsorption, that is, they rely solely on activated carbon to treat the flue gas generated during the incineration process for desulfurization, denitrification and dioxin removal. This can easily lead to activated carbon saturation, resulting in the incompletely treated flue gas spreading into the air and causing environmental pollution. Summary of the Invention

[0017] The present invention provides a waste incineration flue gas desulfurization, denitrification, dioxin removal, and dust removal device, the beneficial effects of which include:
[0018] 1. By setting up a gas-liquid contact mechanism, clean water inside the liquid phase separation tank can be drawn into the cylinder through the suction pipe and rectangular tube under negative pressure. Since the end of the cylinder inside the washing tank is conical, when the cylindrical block moves towards the washing tank and discharges the clean water drawn into the washing tank, it will be discharged with great pressure, thus achieving the washing operation of the exhaust gas entering the washing tank. When the rotating shaft rotates, it can simultaneously drive the atomizing disc and dispersing blades to rotate. The cylinder can spray clean water with a large pressure onto the rotating atomizing disc and dispersing blades, which can break the clean water entering the washing tank into countless small water droplets and fall downwards. These countless small water droplets come into contact with the exhaust gas entering the washing tank, and can then adsorb the dust and particulate matter inside again, thereby achieving the purpose of removing dust and particulate matter from the exhaust gas again.
[0019] 2. By setting up an auxiliary dust removal mechanism, surfactants or other additives that can increase the surface tension of water and additives for adsorbing sulfur and nitrates inside the storage tank can be drawn into the fixed installation cylinder through the adsorption pipe, and then discharged into the hollow tube frame through the conveying pipe. Finally, the liquid is sprayed into the liquid phase separation box through multiple atomizing nozzles at the junction of the vertical and horizontal pipes. Since there are multiple nozzles at the junction of the vertical and horizontal pipes, the atomized liquid can also adsorb the exhaust gas passing through the liquid phase separation box again. The liquid is discharged in an atomized manner, which can greatly increase the contact area between sulfur, nitrates and dust in the exhaust gas, thereby effectively purifying sulfur and nitrates in the exhaust gas, and further removing dust and particulate matter.
[0020] 3. By setting up an adsorption mechanism and controlling the rotation of the motor, the rotating shaft inside the filter cartridge can be driven to rotate. The filter cartridge is filled with activated carbon, which moves continuously upward along the spiral direction of the spiral blades. When it reaches the top of the spiral blades, it automatically falls downward. The continuous movement of the activated carbon can greatly improve its adsorption effect and effectively adsorb sulfur, nitrates, and dioxins in the waste gas. When the waste gas passes through the liquid phase separation tank and the washing tank, the sulfur, nitrates, and dust in the waste gas have already been removed and purified. The activated carbon is mainly used to adsorb dioxins in the waste gas. Therefore, the activated carbon inside the filter cartridge will not have the problem of frequent saturation and replacement.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] Reference Figures 1-9This invention provides a technical solution: a waste incineration flue gas desulfurization, denitrification, dioxin removal, and dust removal device, comprising a liquid phase separation tank 1, a washing tank 2 fixedly installed on the top surface of the liquid phase separation tank 1, an adsorption tank 3 fixedly installed on the top surface of the washing tank 2, two gas outlet pipes 5 installed at the top of the adsorption tank 3, external pipes 4 connected to both sides of the liquid phase separation tank 1, and gas-liquid contact mechanisms 6 provided on both sides of the washing tank 2. In actual use, the exhaust gas after combustion is discharged into the interior of the liquid phase separation tank 1 through the external gas supply equipment via the external pipes 4. At this time, clean water is injected into the interior of the liquid phase separation tank 1, and the height of the clean water is higher than the gas outlet of the external pipes 4. Therefore, when the exhaust gas enters the interior of the liquid phase separation tank 1 through the external pipes 4, it will pass through the interior of the clean water. The contact between the exhaust gas and the clean water can effectively intercept the dust and particulate matter in the exhaust gas, thereby achieving the purpose of intercepting and filtering the dust and particulate matter in the exhaust gas.
[0034] There are two sets of vapor-liquid contact mechanisms 6, which are symmetrically arranged on both sides of the washing tank 2. Each vapor-liquid contact mechanism 6 includes a rectangular frame 61, an L-shaped frame 62 fixedly installed on the top surface of the rectangular frame 61, one side of the L-shaped frame 62 fixedly connected to one side of the adsorption tank 3, a cylinder 63 fixedly connected to one side of the rectangular frame 61, one end of the cylinder 63 extending into the interior of the washing tank 2, and the end of the cylinder 63 inside the washing tank 2 being tapered, a snap-fit block 611 movably inserted into the interior of the rectangular frame 61, a cylindrical block 613 movably inserted into the interior of the cylinder 63, the outer wall of the cylindrical block 613 fitting against the inner wall of the cylinder 63, a connecting plate 612 fixedly connected to one side of the snap-fit block 611, and C-shaped frames 64 fixedly installed on both sides of the rectangular frame 61. An installation shaft 65 is rotatably installed inside the C-shaped frame 64, and a shaped block is fixedly sleeved on the outer surface of the installation shaft 65. 66. The mounting shaft 65 can be connected to an external drive source. The bottom surface of the rectangular frame 61 is provided with a second snap-fit groove 610. The two sides of the rectangular frame 61 are provided with a first snap-fit groove 69. The connecting plate 612 is fixedly inserted with a second fixed shaft 616. The second fixed shaft 616 is movably snapped into the inside of the first snap-fit groove 69. The second snap-fit groove 610 is movably snapped into an outer connecting plate 614. The outer connecting plate 614 is inserted with a first fixed shaft 615. A spring 617 is connected between the outer connecting plate 614 and the first fixed shaft 615. The outer surface of the cylinder 63 is fixedly connected with a rectangular tube 67 and a suction pipe 68. The bottom surface of the rectangular tube 67 is fixedly connected with an air inlet pipe 620. The connection between the air inlet pipe 620 and the rectangular tube 67 and the cylinder 63 is provided with a one-way valve three with opposite flow direction. The bottom surface of the rectangular tube 67 is fixedly connected with a suction pipe 68. One end of the suction pipe 68 extends into the interior of the liquid phase separation tank 1.
[0035] During operation, after the exhaust gas, having passed through the clean water filter, enters the washing tank 2, an external power source drives the mounting shaft 65 to rotate, thereby causing the irregularly shaped block 66 to rotate. As the outer surfaces of the irregularly shaped block 66, with their different diameters, come into contact with the fixed shaft 616, the fixed shaft 616 is fitted inside the connecting plate 612. Since the connecting plate 612, the snap-fit block 611, and the cylindrical block 613 are fixedly connected, the connecting plate 612, the snap-fit block 611, and the cylindrical block 613 can all be rotated. 613 moves back and forth inside the rectangular frame 61, thereby drawing clean water from inside the liquid phase separation tank 1 into the cylinder 63 through the suction pipe 68 and the rectangular pipe 67 under negative pressure. Since the end of the cylinder 63 inside the washing tank 2 is a conical structure, when the cylindrical block 613 moves towards the washing tank 2 and discharges the clean water drawn in from inside the cylinder 63 into the washing tank 2, it will be discharged with great pressure, thus achieving the washing operation of the waste gas entering the washing tank 2.
[0036] The other end of the rotating shaft 84 extends to the bottom surface of the baffle 83 and is fixedly installed with an atomizing disc 618. Multiple dispersing blades 619 are fixedly installed on the outer surface of the atomizing disc 618. The atomizing disc 618 and the dispersing blades 619 are located between two cylinders 63. When the rotating shaft 84 rotates, it can synchronously drive the atomizing disc 618 and the dispersing blades 619 to rotate. The cylinders 63 can spray clean water at a large pressure onto the rotating atomizing disc 618 and the dispersing blades 619, thereby causing the clean water entering the washing tank 2 to be dispersed into countless small water droplets that fall downwards. These countless small water droplets come into contact with the exhaust gas entering the washing tank 2, thereby adsorbing the dust and particulate matter inside again, thus achieving the purpose of removing dust and particulate matter from the exhaust gas again.
[0037] The liquid phase separator 1 is equipped with an auxiliary dust removal mechanism 7, which includes a hollow tube frame 71. The hollow tube frame 71 is fixedly installed on the inner wall of the liquid phase separator 1. Multiple sets of vertical tubes 72 and horizontal tubes 73 are staggered inside the hollow tube frame 71. Atomizing nozzles are installed at the junctions of the vertical tubes 72 and horizontal tubes 73. A positioning plate 76 is fixedly connected to one side of the washing tank 2. Multiple fixed mounting cylinders 74 are fixedly installed below the positioning plate 76. Each fixed mounting cylinder 74 has a sealing plug 710 sealed inside. A connecting rod 711 is fixedly connected to one end of the sealing plug 710. A T-shaped plate 77 is fixedly connected to the bottom surface of the fixed shaft 615. One end of the sealing plug 710 is fixedly connected to one side surface of the T-shaped plate 77. A delivery pipe 78 is fixedly connected to the outer surface of the fixed mounting cylinder 74. One end of the delivery pipe 78 extends into the interior of the liquid phase separation tank 1 and is fixedly connected to one side of the hollow tube frame 71. The delivery pipe 78 and the hollow tube frame 71 are interconnected. An adsorption pipe 79 is fixedly connected to one side of the fixed mounting cylinder 74. A medicine storage tank 75 is fixedly connected to the other end of the adsorption pipe 79. One-way valve 713 and one-way valve 712 are respectively installed on the outer surfaces of the adsorption pipe 79 and the delivery pipe 78.
[0038] During operation, as the connecting plate 612 moves back and forth, it synchronously drives the fixed shaft 615 and the T-shaped plate 77 to move synchronously. This, in turn, drives the connecting rod 711 and the sealing plug 710 to move back and forth inside the fixed mounting cylinder 74. This allows surfactants or other additives that increase the surface tension of clear water, along with additives for adsorbing sulfur and nitrates, from inside the medicine storage tank 75, to be drawn into the fixed mounting cylinder 74 through the adsorption pipe 79, and then discharged into the hollow tube frame 71 through the conveying pipe 78. Then, the atomizing nozzles at the junction of multiple vertical pipes 72 and horizontal pipes 73 spray the liquid into the liquid phase separation box 1. Since there are multiple nozzles at the junction of vertical pipes 72 and horizontal pipes 73, the atomized liquid can also adsorb the waste gas passing through the liquid phase separation box 1 again. The liquid is discharged in an atomized manner, which can greatly increase the contact area with sulfur, nitrate and dust in the waste gas, thereby effectively purifying sulfur and nitrate in the waste gas, and removing dust and particulate matter again.
[0039] Furthermore, after the liquid medicine falls into the liquid phase separation tank 1, it will combine and mix with the clean water inside the liquid phase separation tank 1. During the movement of the cylindrical block 613, the clean water mixed with the liquid medicine is drawn into the cylinder 63 and discharged. In this way, the sulfur and nitrate in the waste gas can be purified again inside the washing tank 2, thereby greatly increasing the purification effect on sulfur and nitrate in the waste gas.
[0040] The adsorption box 3 is equipped with an adsorption mechanism 8, which includes a conical frame 81. The top surface of the conical frame 81 is fixedly connected to the bottom surface of the adsorption box 3. A filter cylinder 82 is fixedly connected to the bottom surface of the conical frame 81. A baffle 83 is fixedly connected to the bottom surface of the filter cylinder 82. An exhaust channel is isolated between the outer surface of the baffle 83 and the inner wall of the washing box 2. One end of the exhaust pipe 5 is located at the conical frame 81. A rotating shaft 84 is rotatably installed at the top of the baffle 83. The other end of the rotating shaft 84 extends to the outside of the adsorption box 3. A motor 86 is fixedly installed at the top of the adsorption box 3. The output end of the motor 86 is fixedly connected to one end of the rotating shaft 84. Spiral blades 85 are fixedly installed on the outer surface of the rotating shaft 84 inside the conical frame 81 and the filter cylinder 82. The filter cylinder 82 is filled with activated carbon.
[0041] During operation, the exhaust gas purified inside the washing tank 2 enters the adsorption tank 3 through the exhaust channel and passes through the filter cartridge 82. At this time, the motor 86 is controlled to rotate, which drives the rotating shaft 84 to rotate inside the filter cartridge 82. Since the filter cartridge 82 is filled with activated carbon, the activated carbon moves within the cartridge, continuously moving upwards along the spiral direction of the spiral blades 85. Upon reaching the top of the spiral blades 85, it automatically falls downwards. This continuous movement of the activated carbon greatly enhances its adsorption effect and... The filter cartridge 82 effectively adsorbs sulfur, nitrates, and dioxins from the exhaust gas. As the exhaust gas passes through the liquid phase separation tank 1 and the washing tank 2, the sulfur, nitrates, and dust in the exhaust gas are already removed and purified. The activated carbon is mainly used to adsorb dioxins in the exhaust gas. Therefore, the activated carbon inside the filter cartridge 82 will not have the problem of frequent saturation and replacement. Furthermore, the rotation of the spiral blades 85 can improve the discharge efficiency of the purified exhaust gas. The exhaust gas is in a spiral upward state inside the filter cartridge 82, which can greatly increase the contact area between the activated carbon and the exhaust gas, thereby improving the adsorption effect of dioxins in the exhaust gas and thus greatly improving the purification effect of the exhaust gas.
[0042] Specifically, the working process or principle of this waste incineration flue gas desulfurization, denitrification, dioxin removal, and dust removal equipment is as follows: During actual use, the exhaust gas after combustion is discharged into the liquid phase separation tank 1 through an external gas conveying device via an external pipe 4. At this time, the liquid phase separation tank 1 is filled with clean water, and the height of the clean water is higher than the gas outlet of the external pipe 4. Therefore, when the exhaust gas enters the liquid phase separation tank 1 through the external pipe 4, it will pass through the clean water. The contact between the exhaust gas and the clean water can effectively intercept the dust and particulate matter in the exhaust gas. When the connecting plate 612 moves back and forth, it can synchronously drive the fixed shaft 615 and the T-shaped plate 77 to move synchronously, thereby driving the connecting rod 711 and... The sealing disc 710 moves back and forth inside the fixed mounting cylinder 74, drawing surfactants or other additives that increase the surface tension of water, along with additives for adsorbing sulfur and nitrates, from the storage tank 75 through the adsorption pipe 79 into the fixed mounting cylinder 74. From there, it is discharged through the delivery pipe 78 into the hollow tube frame 71, and finally sprayed into the liquid phase separation tank 1 through atomizing nozzles at the junction of multiple sets of vertical pipes 72 and horizontal pipes 73. Because there are multiple nozzles at the junction of the vertical pipes 72 and horizontal pipes 73, the atomized liquid can further adsorb the waste gas passing through the liquid phase separation tank 1. The atomized discharge of the liquid greatly increases the contact area with sulfur, nitrates, and dust in the waste gas, thus improving the treatment of the waste gas. The system effectively purifies sulfur and nitrates in the waste gas and removes dust and particulate matter. When the liquid medicine falls into the liquid phase separation tank 1, it combines with the clean water inside the tank. As the cylindrical block 613 moves, it draws the water mixed with the liquid medicine into the cylinder 63 and discharges it. This further purifies the sulfur and nitrates in the waste gas within the washing tank 2, significantly increasing the purification effect. When the connecting plate 612 moves back and forth, it synchronously drives the fixed shaft 615 and the T-plate 77, which in turn drives the connecting rod 711 and the sealing plug 710 to move back and forth inside the fixed mounting cylinder 74, thus purifying the waste gas containing sulfur and nitrates. Surfactants or other additives that increase the surface tension of water, along with additives for adsorbing sulfur and nitrates, are drawn into the fixed mounting cylinder 74 through the adsorption pipe 79. They are then discharged into the hollow tube frame 71 through the delivery pipe 78, and finally sprayed into the liquid phase separation tank 1 through atomizing nozzles at the junction of multiple sets of vertical pipes 72 and horizontal pipes 73. Because there are multiple nozzles at the junction of the vertical pipes 72 and horizontal pipes 73, the atomized liquid can further adsorb the waste gas passing through the liquid phase separation tank 1. The atomized discharge of the liquid greatly increases the contact area with sulfur, nitrates, and dust in the waste gas, thus effectively purifying the sulfur and nitrates and further removing dust and particulate matter.The waste gas purified inside the washing tank 2 enters the adsorption tank 3 through the exhaust channel and passes through the filter cartridge 82. At this point, the motor 86 rotates, driving the shaft 84 to rotate inside the filter cartridge 82. The activated carbon inside the filter cartridge 82 moves upwards along the spiral direction of the spiral blades 85, then automatically falls downwards upon reaching the top of the blades. This continuous movement of the activated carbon greatly enhances its adsorption effect, effectively adsorbing sulfur, nitrates, and dioxins from the waste gas. Since the waste gas has already undergone purification by passing through the liquid phase separation tank 1 and the washing tank 2, and the activated carbon primarily adsorbs dioxins, the activated carbon inside the filter cartridge 82 does not require frequent saturation and replacement.
[0043] It should be noted that the motor 86 is a device or equipment that exists in the prior art, or a device or equipment that can be implemented by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
