Description

Technical Field

[0001] The invention relates to the technical field of dioxin treatment, in particular to a high-voltage pulse device for dioxin treatment. Background Art

[0002] Dioxin is a colorless, odorless, highly toxic, fat-soluble substance containing many homologues or isomers. This type of substance is very stable, has a high melting point, is extremely insoluble in water, can be dissolved in most organic solvents, and easily accumulates in the human and animal bodies. It is highly carcinogenic, teratogenic, and mutagenic, and is often present in the flue gas produced after garbage incineration.

[0003] At present, activated carbon adsorption or wet bag dust removal is usually used to remove dioxins from flue gas from garbage incineration. However, these treatment methods are not ideal for the purification of dioxins. After a long period of adsorption of dioxins, the internal pores of activated carbon are gradually blocked. The adsorption effect of activated carbon will decrease with the increase of adsorption time. The activated carbon needs to be replaced frequently to maintain the adsorption effect. Bag dust removal can only rely on water molecules to remove the tiny fly ash particles adsorbed with dioxins carried in the flue gas, but cannot remove other dioxins that cannot be adsorbed by fly ash.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This high-pressure pulse equipment for dioxin treatment is equipped with a high-pressure pulse purification box, an organic solvent purification box and an activated carbon adsorption box. The flue gas generated by garbage incineration is cooled in the cooling treatment box and then passes into the movable cylinder from the air guide channel. The flue gas flows downward from the gap of the activated carbon filled in the movable cylinder and fully contacts with the activated carbon. The activated carbon performs primary treatment on the dioxins in the flue gas and adsorbs part of the dioxins in the flue gas. After that, the flue gas passes into the annular tube from the second ventilation pipe and enters the organic solvent from the air outlet. During the process of the flue gas floating in the organic solvent, it contacts with the activated carbon. The organic solvent is fully in contact, and the dioxins in the flue gas are subjected to secondary treatment by the organic solvent to dissolve part of the dioxins. Then the flue gas enters the high-voltage pulse purification box from the third ventilation pipe, and the discharge electrodes discharge to form high-concentration charged ions in the high-voltage pulse purification box. The ions collide with each other in the electric field, and the dioxins in the flue gas are subjected to tertiary treatment to directly ionize the dioxins to form hydrogen radicals, hydroxyl radicals and free radicals. Through three treatments, a large amount of dioxins in the flue gas from garbage incineration can be effectively removed, ensuring that the dioxin content in the flue gas is within the national emission standards when it is discharged.

[0019] 2. The high-pressure pulse equipment for dioxin treatment is provided with a high-temperature steam reduction box. The pores of the activated carbon in the movable cylinder are blocked after long-term adsorption of dioxins. The motor drives the rotating shaft to rotate, and the rotating shaft drives the partition to rotate. The partition drives the movable cylinder to rotate 180 degrees in the through groove, and the positions of the two adsorption chambers are exchanged, so that the activated carbon with blocked pores is transferred from the activated carbon adsorption box to the high-temperature steam reduction box. The internal pure water is heated by the annular heating component to boil the water to generate high-temperature steam. The high-temperature steam passes through the annular plate and the hollow net and fully contacts with the activated carbon. The high-temperature steam heats the activated carbon to carbonize or desorb the impurities adsorbed inside it, so that it restores its original activity. The activated carbon in the two adsorption chambers is driven by the rotating shaft to be flipped and used alternately. The activated carbon on one side is used for dioxin adsorption while the activated carbon on the other side restores the adsorption performance at high temperature, which avoids the trouble of regular replacement of activated carbon and maintains a sufficient adsorption effect on dioxins.

[0020] 3. The high-pressure pulse equipment for dioxin treatment is provided with a cooling treatment box. The flue gas is passed into the cooling cylinder through the air inlet pipe, and cold water is passed into the water flow channel through the water inlet pipe. The copper metal cooling cylinder transfers the heat in the flue gas to the cold water, so that the cold water and the flue gas form a heat exchange, the flue gas is cooled, and the cold water is heated. When the water level in the water flow channel rises to the water outlet, the water flows through the fixed plate to one side and then flows into the high-temperature steam reduction box through the water outlet pipe. The cold water in the water flow channel is used for both cooling the flue gas and using the heat in the flue gas for the generation of high-temperature steam, thereby reducing the energy consumption of the annular heating component and making the activated carbon active reduction treatment process more energy-saving and environmentally friendly.

[0021] 4. The high-voltage pulse equipment for dioxin treatment is provided with an insert block and a slot. During the process of the rotating shaft driving the movable cylinder to rotate through the partition, when the insert block contacts the inner wall of the through slot and the side plate, the inner wall of the through slot and the side plate squeeze the oblique edge of the insert block, so that the insert block shrinks into the slide slot, and the spring is compressed. When the position of the insert block corresponds to the slot, the spring rebounds and pushes the insert block into the slot. The movable cylinder is positioned by the insertion of the insert block and the slot, and the accuracy of the two adsorption chambers being connected to the activated carbon adsorption box and the high-temperature steam reduction box is maintained.

[0036] Specifically, a first ventilation pipe 33 is connected to the top of the activated carbon adsorption box 3, which is used to connect the activated carbon adsorption box 3 and the cooling cylinder 51. An air guide channel 32 is opened inside the activated carbon adsorption box 3 at the bottom of the first ventilation pipe 33.

The rotating shaft 66 is driven to rotate by the motor 34, and the rotating shaft 66 drives the partition 61 to rotate.

[0044] Furthermore, the cooling tube 51 is made of copper metal, and the cooling tube 51 made of copper metal transfers the heat in the flue gas to the cold water, so that the cold water and the flue gas form heat exchange, the flue gas is cooled, and the cold water is heated. One side of the water flow channel 53 is connected to the water tank 58 through the water inlet pipe 56, and the other side of the water flow channel 53 is connected to the inner cavity of the high-temperature steam reduction box 4 through the water outlet pipe 59. The cold water in the water flow channel 53 is used for both cooling the flue gas and using the heat in the flue gas for the generation of high-temperature steam, thereby reducing the energy consumption of the annular heating component 41 and making the activated carbon active reduction treatment process more energy-saving and environmentally friendly.

[0045] The method of use of this embodiment is as follows: when the user actually treats the dioxins in the flue gas generated after the incineration of garbage, the user first starts the water pump 57, and the water pump 57 passes the cold water stored in the water tank 58 into the water flow channel 53 through the water inlet pipe 56, and then passes the incinerated flue gas from the air inlet pipe 52 into the cooling cylinder 51, and the cooling cylinder 51 made of copper metal transfers the heat in the flue gas to the cold water, so that the cold water and the flue gas form a heat exchange, the flue gas cools down, and the cold water heats up, and then the flue gas enters the air guide channel 32 from the first ventilation pipe 33, and passes into the four movable cylinders 6 from the air guide channel 32, and the flue gas flows downward from the gaps of the activated carbon filled in the movable cylinder 6, and fully contacts with the activated carbon, and the activated carbon performs primary treatment on the dioxins in the flue gas, adsorbs part of the dioxins in the flue gas, and the adsorbed flue gas enters the activated carbon absorption tank from the hollow mesh 65 at the bottom of the movable cylinder 6 In the auxiliary box 3, the flue gas is then passed into the annular tube 21 from the second ventilation pipe 23, and the flue gas in the annular tube 21 enters the organic solvent from the air outlet 22. The flue gas fully contacts the organic solvent during the process of floating in the organic solvent, and the organic solvent performs secondary treatment on the dioxins in the flue gas, dissolving part of the dioxins. The flue gas floating upward enters the hollow groove 17 from the third ventilation pipe 25, and is diverted through the air outlet 18 and passed into the high-voltage pulse purification box 1. The discharge electrode 11 discharges to form high-concentration charged ions in the high-voltage pulse purification box 1, and collides with each other in the electric field, and performs tertiary treatment on the dioxins in the flue gas, so that the dioxins are directly ionized to form hydrogen radicals, hydroxyl radicals and free radicals. The particulate fly ash in the flue gas adheres to the surface of the discharge electrode 11, and falls off to the bottom of the high-voltage pulse purification box 1 after long-term accumulation. The flue gas after tertiary treatment is finally discharged from the air outlet 13;When the pores of the activated carbon in the activated carbon adsorption box 3 are clogged after long-term use, the motor 34 drives the shaft 66 to rotate, the shaft 66 drives the partition 61 to rotate, and the partition 61 drives the movable cylinder 6 to rotate 180° in the through groove 31, and the movable cylinder 6 drives the plug blocks 64 on both sides to move, and the through groove 31 makes the inner wall of the through groove 31 squeeze the oblique edge of the plug block 64, so that the plug block 64 shrinks and enters the slide groove 62, and the spring 63 is compressed. When the movable cylinder 6 rotates 180° and the plug block 64 corresponds to the position of the slot 310, the spring 63 rebounds and pushes the plug block 64 into the slot 310. The movable cylinder 6 is positioned by the plug block 64 and the slot 310, and the positions of the two adsorption chambers are exchanged, so that the activated carbon with clogged pores is transferred from the activated carbon adsorption box 3 to the high-temperature steam reduction box 4, and the activated carbon transferred from the high-temperature steam reduction box 4 to the activated carbon adsorption box 3 continues to be used for dioxin adsorption. At the same time, the plug block 64 squeezes the pressure sensor 311 in the slot 310, and the pressure sensor 311 in the slot 310 is compressed. The force sensor 311 detects the squeezing force and transmits a signal to the control box 7. The control box 7 controls the air pump 39 to start. The air pump 39 inflates the ventilation branch pipe 37 through the ventilation main pipe 38. The air flows into the sealing airbag 36 to expand it, so that the sealing airbag 36 is close to the outer wall of the movable cylinder 6, and the gap between the movable cylinder 6 and the through groove 31 is sealed. Then, the internal pure water is heated by the annular heating component 41 to boil the water and generate high-temperature steam. The high-temperature steam passes through the annular plate 43 and the hollow mesh 65 and fully contacts the activated carbon. The high-temperature steam heats the activated carbon to carbonize or desorb the impurities adsorbed inside it, so that it restores its original activity. When the liquid level sensor 42 detects that the water level in the high-temperature steam reduction box 4 is low, the water outlet valve 510 is opened to allow the water carrying the heat of the flue gas in the water flow channel 53 to enter the high-temperature steam reduction box 4 from the water outlet pipe 59, and the heat in the flue gas is used to generate high-temperature steam, thereby reducing the energy consumption of the annular heating component 41. ;
