Description

Technical Field

[0001] The utility model relates to the technical field of flue gas purification, in particular to a high-efficiency flue gas purification device for a garbage incinerator. Background Art

[0002] With the acceleration of urbanization and the continuous growth of population, the disposal of domestic waste has become an urgent problem. Traditional landfill methods not only occupy a large amount of land resources, but may also cause groundwater and soil pollution. Waste incineration technology, as an effective waste disposal method, has attracted much attention because it can significantly reduce the volume of waste and achieve energy recovery and utilization. However, the flue gas generated during the waste incineration process contains a variety of pollutants, such as sulfur dioxide, nitrogen oxides, particulate matter, heavy metals and dioxins. If these pollutants are directly discharged into the atmosphere without effective treatment, they will have a serious impact on the environment and human health.

[0003] For example, a Chinese patent proposes a flue gas purification device for a domestic waste incinerator (patent announcement number CN214468657U). The device is equipped with a stirring rod and a stirring blade. When the stirring rod rotates, the stirring blade stirs the adsorption liquid, which can increase the contact area between the flue gas and the adsorption liquid, effectively increasing the effect of flue gas purification. At the same time, the stirring blade causes the adsorption liquid to rotate, which can prevent the effective substances in the adsorption liquid from precipitating, causing the adsorption liquid to lose its purification ability, and can enable the adsorption liquid to maintain a long-term and stable purification effect. However, although the above patent has solved the problem of flue gas purification to a certain extent, there are still some shortcomings. For example, when the device processes flue gas with complex components, it cannot filter the flocs generated by incomplete combustion inside it, and the adsorption liquid also needs to be replaced and cleaned after a period of use, which is relatively limited.

[0004] In order to solve the above problems, while achieving higher purification efficiency, further reduce the pollutant emissions generated during the waste incineration process and protect the environment and human health, we have proposed a high-efficiency flue gas purification device for waste incinerators.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-3 A high-efficiency flue gas purification device for a waste incinerator includes a connecting pipe 1, a filter box 2 for filtering is fixedly installed on the top of the connecting pipe 1, and diversion pipes 3 for diversion are fixedly installed on both sides of the top of the filter box 2, and the diversion pipes 3 are L-shaped as a whole, and the other ends of the diversion pipes 3 are fixedly installed on the bottom of the purification box 4, and also include:

[0027] Purification component, the purification component is arranged inside the purification box 4, the purification component is used to purify the filtered flue gas, the purification component includes a supporting seat 10, a purification box 11 and a through hole 12, the inner wall surface of the purification box 4 is fixedly installed with a supporting seat 10 for carrying, and a purification box 11 for purification is placed on the top of the supporting seat 10, and through holes 12 for flue gas circulation are provided on both sides of the purification box 11. Through the setting of the purification component, the purification efficiency of the flue gas can be significantly improved and harmful substances can be removed. At the same time, the modular structure is adopted to facilitate assembly, disassembly and replacement, improve the maintainability of the equipment, and ensure the smooth circulation of the flue gas, thereby enhancing the purification effect.

[0028] Furthermore, a cleaning groove 5 for installation is opened on one side of the filter box 2, and a side panel 6 for closing is slidably installed inside the cleaning groove 5. Through the setting of the cleaning groove 5 and the side panel 6, the filter 7 can be conveniently installed and disassembled, which not only facilitates the regular replacement or maintenance of the filter 7, but also improves the use flexibility and maintenance convenience of the entire purification device, thereby ensuring the continuity and stability of the flue gas purification effect.

[0029] Furthermore, a number of filter screens 7 for filtering are fixedly installed at equal intervals on the other side of the side panel 6. The setting of the filter screens 7 effectively increases the filtering area and improves the filtering efficiency. This multi-layer, multi-point filtering design can more fully capture and remove particulate matter and harmful substances in the flue gas, further improving the purification ability of the purification device for the flue gas, and helping to reduce environmental pollution and protect the air quality.

[0030] Furthermore, a baffle 8 for blocking and protecting is fixedly installed on the inner wall surface of the filter box 2 at a position corresponding to the connecting pipe 1 .

[0031] Furthermore, atomizing nozzles 9 for atomization are fixedly installed on both sides of the top of the filter box 2. Through the setting of the atomizing nozzles 9, water or other purification liquids can be atomized and sprayed into the flue gas, which helps to reduce the temperature of the flue gas and increase its humidity, thereby facilitating the subsequent filtration and purification process. In addition, the atomization treatment can further remove some flocs or dust in the flue gas, improve the purification effect, and help reduce the pollution of the flue gas to the environment.

[0032] Furthermore, the interior of the purification box 11 is also filled with a mixed filler for purification, which includes but is not limited to bamboo charcoal particles, zeolite particles, ceramic particles, activated carbon fibers and glass fibers.

[0033] Furthermore, the interiors of the two groups of diversion tubes 3 are filled with activated carbon bags for preliminary purification. Through the setting of the activated carbon bags filled in the diversion tubes 3, the flue gas can be preliminarily filtered and purified before entering the purification component, removing some large particles and easily adsorbed harmful substances. This preliminary purification design not only reduces the burden on subsequent purification components and improves the overall purification efficiency, but also helps to extend the service life of the purification device and reduce maintenance costs. At the same time, the replacement of the activated carbon bags is relatively simple and convenient, which is convenient for users to perform daily maintenance and replacement.

[0034] Instructions

[0035] When in use, first install the entire device on the top of the garbage incinerator through the connecting pipe 1. Then the flue gas generated by the burning of garbage in the garbage incinerator will enter the interior of the filter box 2 through the guidance of the connecting pipe 1. At this time, several water pipes are connected to the back side of the atomizing nozzle 9, and the water liquid is atomized through the atomizing nozzle 9 to be spread inside the filter box 2. When the flue gas enters the interior of the filter box 2, the dust, particles, flocs and other impurities contained therein will combine with the water mist, thereby increasing its mass and falling down according to gravity until it is intercepted by the filter 7. After that, the filtered flue gas will enter the interior of the purification box 4 through the diversion pipes 3 on both sides of the filter box 2. When entering the interior of the diversion pipe 3, the activated carbon bag filled in the diversion pipe 3 can be used to preliminarily filter and purify the flue gas before it enters the purification component, removing some large impurities. Particulate matter and easily adsorbed harmful substances reduce the burden of subsequent purification components and improve the overall purification efficiency. The flue gas will then enter the interior of the purification box 4, and then the flue gas will enter the interior of the purification box 11 through the through hole 12. Through the mixed filler inside the purification box 11, various harmful substances in the flue gas are efficiently removed, and then the purified flue gas can be tested. After the test shows that it meets the emission standards, the top cover of the purification box 4 can be opened to discharge it. If the emission standards are not met, a new connecting pipe can be installed and introduced into the interior of another set of purification devices for secondary purification, thereby completing the flue gas purification process. Through the mutual cooperation between the above-mentioned structures, this device can further reduce the emission of pollutants generated during the waste incineration process while achieving higher purification efficiency, protecting the environment and human health, and being more environmentally friendly and practical.
