The cleaning device 1 comprises a cleaning box 11. A partition 12 is fixedly provided in the cleaning box 11. A smoke outlet 122 is provided on the partition 12. The lower end of the smoke outlet 122 is connected to the lower cavity formed by the partition 12. The bottom of the cleaning box 11 is rotatably provided with fan blades 112. The fan blades 112 are used to guide and transport the flue gas at the bottom of the partition 12 upward, and at the same time, accelerate the flow of the flue gas in the cavity formed at the bottom of the partition 12, so as to make the flue gas fully contact with the fluid by accelerating the flow of the flue gas in the cleaning box 11. , to improve the dust removal and cleaning effect of the flue gas, the top of the smoke outlet 122 is provided with a plurality of atomizing nozzles 132, which atomize the fluid and can improve the contact between the atomized fluid and the particles in the flue gas. The top of the atomizing nozzle 132 is provided with a demister 15, and the atomizer dries the cleaned flue gas to facilitate subsequent combustion; in the copper hot rolling production, the emulsion is instantly atomized into smoke when it encounters the high-temperature copper ingot, and the smoke gas contains harmful gases and emulsion. By passing the smoke through the cleaning device 1, the atomizing nozzle 132 in the cleaning device 1 is sprayed, so that the dust particles and the emulsion in the smoke are cleaned and filtered into the cleaning box 11, so that the emulsion is recycled and the production cost is reduced;

[0039] The filter device 2 is used to filter harmful gases in the cleaned flue gas. The cleaned flue gas is transported to the filter device 2. The filter device 2 is a prior art device, and is provided with filter cotton and adsorption cotton inside. It can preliminarily adsorb the gas that can be adsorbed and treated in the cleaned flue gas and filter out the small impurity particles and harmful gases that have not been cleaned in the flue gas, so as to reduce the types of harmful gases in the combustion process.

[0040] The combustion device 3 is used to burn the flue gas that is difficult to clean in the cleaning device 1 and the filtering device 2. Most of the unfiltered gases are organic gases. The flue gas is directly burned to burn the organic gases in the flue gas to form water and carbon dioxide, so as to treat the gases that are difficult to filter and make the products after combustion meet the environmental emission standards. The combustion device 3 includes a cylinder 32, the interior of the cylinder 32 is connected to the output end of the filtering device 2, and the cylinder 32 forms an upper cavity 321 and a lower cavity 322 through a cavity plate 323. The upper cavity 321 serves as a combustion chamber for the flue gas, and the lower cavity 322 serves as a mixing chamber for the flue gas. A burner 3211 is fixedly provided on the plate 323, and the upper cavity 321 and the lower cavity 322 are interconnected. A combustible gas supply assembly 33 for conveying combustible gas to the interior of the upper cavity 321 is provided on the circumference of the upper cavity 321. The combustible gas supply assembly 33 can supply combustible gas to the upper cavity 321 serving as a combustion chamber to avoid extinguishing of the burner 3211 or a small combustion flame due to too low a concentration of combustible gas in the upper cavity 321. The lower cavity 322 is used for premixing of flue gas before combustion of the flue gas, wherein the explosion concentration limit can be reduced by introducing inert gas into the lower cavity 322 to avoid explosion of flue gas during combustion.

[0041] The activated carbon adsorption device 4 is used to filter and adsorb harmful gases and particulate matter in the flue gas after combustion. Since the emulsion contains sulfur element, sulfur element forms sulfur oxides after combustion. The activated carbon adsorption device 4 is used to adsorb harmful gases formed after combustion. The multi-layer filter adsorption cotton provided inside the activated carbon adsorption device 4 is used to adsorb the flue gas formed after combustion, remove nitrogen oxides, sulfur oxides and odorous gases in the flue gas, and process the sulfide and oxide gases formed after combustion, so that the final emitted gas is carbon dioxide, which meets the emission standards;

[0042] The cleaning device 1 also includes:

[0043] The spray assembly 13 is located directly above the smoke outlet 122, and includes a spray pipe 131. One end of the spray pipe 131 extends to the bottom of the cavity of the cleaning box 11, and is connected to a water pump 133. A plurality of atomizing nozzles 132 are evenly distributed on the spray pipe 131 and are connected to the spray pipe 131. The cleaning box 11 is divided into two cavity spaces by a partition 12, wherein a fluid is stored in the lower cavity formed by the division, and the fluid is extracted and transported under the action of the water pump 133. The extracted fluid is atomized and sprayed into the upper cavity formed by the division through the atomizing nozzle 132. During the atomizing and spraying process, the smoke in the upper cavity is cleaned, so that the dust particles in the smoke and the residual emulsion carried by the smoke are cleaned by the atomizing nozzle 132;

[0044] The air permeable plate 14 is fixedly connected in the cleaning box 11 and is located at a side of the spray pipe 131 away from the smoke outlet 122. The air permeable plate 14 is provided with air holes. The air permeable plate 14 is provided with a plurality of air permeable holes so that the smoke after being cleaned can be discharged through the air permeable holes. The bottom surface of the air permeable plate 14 can block the atomized fluid to a certain extent, so as to prevent excessive atomized water vapor from being discharged from the cleaning box 11 through the air outlet 114.

[0045] The demister 15 is fixedly mounted on one side of the air permeable plate 14 and is used for demistering the smoke after cleaning and filtration. Its input end faces the air permeable plate 14 and its output end is connected to the air outlet 114 to achieve drying of the cleaned smoke.

[0046] An air outlet 114 is provided on the top of the cleaning box 11, an air inlet 113 is provided on one side of the cleaning box 11, and a rectangular groove 121 is opened on the partition 12. The height of the air inlet 113 on the cleaning box 11 is lower than the installation height of the rectangular groove 121 on the cleaning box 11, which can avoid the height of the liquid level blocking the air inlet 113 from passing smoke. In this embodiment, four smoke outlets 122 are provided on the partition 12, wherein the rectangular groove 121 on the partition 12 avoids the smoke outlet 122, and the rectangular groove 121 is used to drain the fluid in the upper cavity formed by the partition 12, and at the same time, increase the contact area between the smoke and the fluid to improve the cleaning effect of the smoke.

[0047] A rotating shaft 111 is rotatably provided between the bottom of the cleaning box 11 and the partition 12, and the rotating shaft 111 is colinear with the axis of the smoke outlet 122. The fan blades 112 are fixedly connected to the rotating shaft 111. The rotation of multiple rotating shafts 111 is driven by an external motor of the cleaning box 11 to rotate the fan blades 112 in the cleaning box 11 to guide the smoke in the lower cavity of the partition 12. The rotation of the fan blades 112 can realize the amount of smoke transmitted through the gas collecting hood to control the cleaning speed of the smoke by the cleaning device 1, and can accelerate the flow speed of the smoke to increase the contact with the atomized water vapor.

[0048] The combustion device 3 also includes a support frame 31, the cylinder 32 is fixedly mounted on the support frame 31, and the combustible gas supply assembly 33 is fixedly connected to one side of the cylinder 32. The support frame 31 is used to support the cylinder 32 and the combustible gas supply assembly 33. In the direct combustion of the upper cavity 321, the combustible gas supply assembly 33 is used to input combustible gas into the cylinder 32 to prevent the burner 3211 from burning out or having a small flame due to too low a concentration of combustible gas inside.

[0049] The combustible gas supply assembly 33 comprises:

[0050] The supply ring 331 is sleeved on the circumference of the cylinder 32, and a supply flow channel 3311 is formed inside the supply ring 331, which is connected with the upper cavity 321. The supply ring 331 is used to transport combustible gas into the cylinder 32, wherein the combustible gas is preferably hydrogen as an auxiliary fuel, and hydrogen as a clean energy is burned to form water, so that the combustion process of the upper cavity 321 can adapt to low-concentration organic smoke and avoid secondary pollution caused by combustion. The hydrogen can be an ammonia decomposition furnace in a production workshop, which reduces the operating cost of the direct combustion method;

[0051] The supply box 332 is fixedly mounted on the combustion device 3 and is connected to the supply ring 331 through a pipeline, and is used to store auxiliary fuel to supply auxiliary fuel to the upper cavity 321, supply combustible gas for the combustion of flue gas, ensure the size of the flame burning in the upper cavity 321, and make the flue gas fully burn to form water and carbon dioxide;

[0052] The supply branch pipe 333 has one end connected to the supply ring 331 and the other end connected to the upper cavity 321 . The supply branch pipe 333 is used to evenly supply and transport the auxiliary fuel into the cylinder 32 .

[0053] The supply branch pipes 333 are provided in plurality, and the plurality of supply branch pipes 333 are distributed in a circular array along the supply ring 331. The plurality of supply branch pipes 333 are used to uniformly supply auxiliary fuel to the circumference of the burner 3211 to ensure the size of the flame of the burner 3211 to ensure sufficient combustion of the organic gas.

[0054] The dividing chamber plate 323 is provided with a plurality of air guide pipes 3212, and the upper cavity 321 and the lower cavity 322 are connected to each other through the air guide pipes 3212. The top of the air guide pipes 3212 is curved and bent toward the burner 3211. The air guide pipes 3212 are used for the connection between the upper cavity 321 and the lower cavity 322, wherein the upper cavity 321 is used for the combustion of flue gas, and the lower cavity 322 is used for the adjustment of flue gas concentration. The flue gas contains a large amount of organic gases, which are all combustible gases. Especially when the gas concentration is high, the temperature rises rapidly during combustion, resulting in excessive pressure in the upper cavity 321 and explosion. By transporting inert gas into the flue gas according to the concentration of the flue gas in the lower cavity 322 for mixing, the stability of the flue gas during combustion is improved to avoid explosion during combustion.

[0055] A driving motor 3223 is provided at the bottom of the lower cavity 322, and a rotating frame 3221 is provided at the output end of the driving motor 3223. A baffle 3222 is fixedly provided on the rotating frame 3221. The width of the baffle 3222 is greater than the diameter of the air duct 3212. The driving motor 3223 drives the baffle 3222 to rotate. When the baffle 3222 rotates to the bottom of the air duct 3212, the baffle 3222 blocks the conduction state of the air duct 3212, thereby controlling the conduction state between the upper cavity 321 and the lower cavity 322, further realizing the supply control of the smoke combustion, so that the smoke stays in the upper cavity 321 for a sufficient time to complete sufficient combustion. At the same time, the blocking of the air duct 3212 by the baffle 3222 can improve the mixing uniformity of the smoke in the lower cavity 322, thereby avoiding explosion during combustion.

[0056] An air inlet interface is provided at the bottom of the lower cavity 322, and a partition is provided inside the air inlet interface. The air inlet interface is used to transport smoke and concentration regulating gas into the lower cavity 322, and the partition of the air inlet interface is used to introduce smoke or inert gas into the lower cavity 322 respectively.

[0057] Working principle of the present invention:

[0058] During the hot rolling production process of copper, the emulsion is instantly atomized into smoke dust when it encounters the high-temperature copper ingot, and is extracted through the gas collecting hood and transported to the cleaning device 1 for cleaning, the filtering device 2 for primary filtration, the combustion device 3 for combustion treatment, and the activated carbon adsorption device 4 for secondary adsorption and filtration, and finally the products of the smoke combustion are water and carbon dioxide, so that the exhaust smoke meets the emission standards after treatment;

[0059] In the cleaning device 1, the smoke first enters the lower cavity formed by the partition plate 12 through the air inlet 113, and the smoke is guided through the smoke outlet 122 into the upper cavity formed by the partition plate 12 under the action of the fan blade 112 driven by the air inlet 113. The fluid is stored at the bottom of the cleaning box 11, and the water pump 133 extracts the fluid and sprays it through the atomizing nozzle 132. The smoke in the cleaning box 11 is cleaned under the action of the atomizing spray, so that the dust particles in the smoke and the smoke are The residual emulsion on the belt is cleaned, and the fluid flows into the bottom of the cleaning box 11 through the rectangular groove 121, so that the fluid circulates in the cleaning box 11, and continuously cleans the flue gas delivered by the air inlet 113. The cleaned flue gas passes through the air holes opened on the air permeable plate 14 and enters the demister 15. The air permeable plate 14 can block the humid flue gas and water vapor. To a certain extent, the bottom surface of the air permeable plate 14 can gather the flue gas and water vapor, and finally form water droplets that drip downward to reduce the humidity of the flue gas entering the demister 15.

[0060] The filter device 2 uses a filter sheet to filter and adsorb particles with smaller diameters in the smoke and harmful gases that can be adsorbed and filtered;

[0061] In the combustion device 3, one of the air inlet interfaces is connected to the output end of the filter device 2, and a control valve is provided on the connecting pipeline, so that the flue gas in the activated carbon adsorption device 4 is transported to the lower cavity 322 through the air inlet interface. The lower cavity 322 controls the amount of inert gas input through the air inlet interface according to the concentration of the input flue gas, so that the flue gas and the inert gas are premixed in the lower cavity 322, so as to avoid the explosion caused by the direct introduction of the flue gas into the upper cavity 321;

[0062] After the flue gases are mixed in the lower cavity 322, the rotating frame 3221 is driven to rotate by the driving motor 3223 in the lower cavity 322. A baffle 3222 is fixedly provided on the rotating frame 3221. When the baffle 3222 rotates to the lower end of the air guide pipe 3212, the mutual communication between the upper cavity 321 and the lower cavity 322 can be blocked. The lower cavity 322 is controlled to supply flue gases to the upper cavity 321 through the rotation of the baffle 3222, so as to realize intermittent delivery of flue gases to the upper cavity 321. On the one hand, it is avoided that the flue gases in the upper cavity 321 are driven to be discharged directly from the upper cavity 321 without being burned due to the pressure of the flue gas delivery, so as to ensure that the flue gases in the upper cavity 321 are fully burned in sufficient time and without being affected by pressure. On the other hand, it provides mixing time for the flue gases in the lower cavity 322 and the inert gas.

[0063] When the combustible gas concentration in the upper cavity 321 is too low during combustion, in order to avoid vigorous combustion of the burner 3211 flame, the combustible gas is transported to the upper cavity 321 through the cavity plate 323 through the upper cavity 321 and the supply branch pipe 333 to ensure the size of the combustion flame in the upper cavity 321, thereby avoiding incomplete combustion of smoke due to insufficient combustion gas;

[0064] The activated carbon adsorption device 4 absorbs and filters harmful gases formed after combustion through the internal multi-layer adsorption filter cotton, and finally the exhaust flue gas is treated, and the final product is water and carbon dioxide that meet the emission standards.
