Description
Technical Field
[0001] The utility model relates to the technical field of denitration and dust removal, in particular to an integrated treatment device for denitration and dust removal for industrial kilns and garbage incineration. Background Art
[0002] Waste incineration and industrial kiln production processes generate a large amount of high temperature, dust, and NO X Flue gas, the flue gas composition is relatively complex, so the flue gas needs to be treated to avoid the damage to the environment after the flue gas is directly discharged. The flue gas is often removed by the dust collector and then connected to the denitrification reactor to ensure that the flue gas can remove the internal smoke and NO X Remove the substance.
[0003] However, most flue gas dust collectors and denitrification reactors are relatively independent, resulting in poor synergy when connected with supporting equipment. For example, when connected with waste heat boilers, the environmental protection system process is lengthy, with many devices, high resistance, and limited energy-saving and emission reduction effects, resulting in low efficiency in flue gas treatment. Utility Model Content
[0004] The purpose of the utility model is to provide an integrated denitrification and dust removal treatment device for industrial kilns and waste incineration, so as to solve the problem of poor synergistic effect when treating flue gas from industrial kilns and waste incineration proposed in the above background technology.
[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an integrated treatment device for denitrification and dust removal for industrial kilns and waste incineration, comprising a raw flue gas inlet, a clean flue gas outlet, a reactor shell, a dust filter cartridge, an ash outlet, an ash hopper and an air bag. A raw flue gas inlet is provided on one side of the reactor shell, a clean flue gas outlet is provided on the side of the reactor shell away from the raw flue gas inlet, a dust filter cartridge is provided inside the reactor shell, an ash hopper is provided at the bottom end of the reactor shell, an ash outlet is provided at the bottom end of the ash hopper, an air bag is installed at one end of the reactor shell, and a clean air bin is provided at the top of the reactor shell.
[0006] Preferably, one end of the clean gas bin is connected to a flue, and a denitration catalyst is provided between the flue and the clean gas bin.
[0007] Preferably, the output end of the air bag is connected to evenly distributed blowing pipes through a conduit.
[0008] Preferably, a protective frame is provided on the surface of the ash hopper, a mounting seat is provided inside the protective frame, and a driving motor is installed on the top of the mounting seat.
[0009] Preferably, the output end of the driving motor is connected to a rotating rod via a coupling, and one end of the rotating rod is provided with symmetrically distributed adjustment plates.
[0010] Preferably, a fixing seat connected to the ash hopper is provided on one side of the protective frame close to the mounting seat, and a knocking plate is rotatably connected to one side of the fixing seat through a rotating shaft, and a limiting spring connected to the ash hopper is provided at one end of the knocking plate.
[0011] Compared with the existing technology, the beneficial effect of the utility model is that the integrated denitrification and dust removal device for industrial kilns and garbage incineration can discharge the generated flue gas into the reactor shell, filter the flue gas through the dust removal filter cartridge and then discharge it into the clean gas bin, so that NO X The flue gas that has been treated can be discharged into the clean flue gas outlet through the flue and then enter the subsequent work section. By starting the driving motor, the rotating rod can hit the knocking plate through the adjusting plate, so that the knocking plate can squeeze the limiting spring, and with continuous rotation, the adjusting plate and the knocking plate can be separated, so that the knocking plate can hit the ash hopper after resetting, thereby facilitating the subsequent discharge of dust and particulate matter.
[0012] 1. The integrated denitrification and dust removal treatment device for industrial kilns and waste incineration can be used to allow the flue gas generated by industrial kilns and waste incineration to enter the reactor shell from the original flue gas inlet. After passing through the dust removal filter cartridge, the dust will adhere to the surface of the dust removal filter cartridge. Then the flue gas will enter the clean air bin and remove dust and particulate matter. At the same time, the smoke that has been cleaned of dust and particulate matter can contact the denitrification catalyst along the flue inside the clean air bin, so that NO X The flue gas that has been treated can be discharged into the clean flue gas outlet through the flue and then enter the subsequent process section, so that the flue gas can quickly enter the subsequent denitrification process after dust removal, avoiding the alkaline dust contained in the flue gas particles, which has a greater impact on the denitrification catalyst and is easy to cause catalyst poisoning, thereby greatly extending the life of the denitrification catalyst and the denitrification effect;
[0013] 2. The integrated denitrification and dust removal treatment device for industrial kilns and waste incineration is easy to cause dust and particulate matter to adhere to the inner wall when the denitrification and dust removal integrated treatment device is in use, making it inconvenient to discharge the dust and particulate matter later. The driving motor can be started so that the driving motor can rotate the rotating rod connected to the output end, so that the rotating rod can hit the knocking plate through the adjusting plate, so that the knocking plate can rotate with the rotating shaft, so that the knocking plate can squeeze the limiting spring, and as the adjusting plate rotates, it can separate from the knocking plate, so that the knocking plate loses its restriction, and the limiting spring can be reset, so that the knocking plate can hit the ash hopper after resetting, so that the vibration of the impact can shake off the dust and particulate matter attached to the surface, thereby facilitating the subsequent discharge of dust and particulate matter.

At the same time, the compressed air in the air bag 7 can be controlled by the electronic control system to be ejected along the injection pipe 11, thereby removing the dust and particulate matter attached to the surface of the dust filter cartridge 4 and causing it to fall into the ash hopper 6. The dust and particulate matter can be cleaned regularly through the ash drop port 5. At the same time, the smoke that has been cleaned of dust and particulate matter can contact the denitrification catalyst 9 along the flue 10 inside the clean air bin 8, so that the denitrification of NO can be completed. X The flue gas that has been treated can be discharged into the clean flue gas outlet 2 through the flue 10 and then discharged, and then can enter the subsequent process section, so that the flue gas can quickly enter the subsequent denitrification section after dust removal, avoiding the alkaline dust that may be contained in the flue gas particles, which has a greater impact on the denitrification catalyst 9 and is easy to cause catalyst poisoning, thereby greatly improving the life of the denitrification catalyst 9 and the denitrification effect.

The flue gas generated by industrial kilns and garbage incineration enters the reactor shell 3 from the original flue gas inlet 1, passes through the dust removal filter cartridge 4, and causes dust to adhere to the surface of the dust removal filter cartridge 4. Then the flue gas will enter the clean air bin 8, and the dust and particulate matter can be removed. At the same time, the smoke that has been cleaned of dust and particulate matter can contact the denitrification catalyst 9 along the flue 10 inside the clean air bin 8, so that the denitrification of NO can be completed. X The flue gas that has been treated can be discharged into the clean flue gas outlet 2 through the flue 10 and then discharged, and then can enter the subsequent process section, so that the flue gas can quickly enter the subsequent denitrification section after dust removal, avoiding the alkaline dust that may be contained in the flue gas particles, which has a greater impact on the denitrification catalyst 9 and is easy to cause catalyst poisoning, thereby greatly improving the life of the denitrification catalyst 9 and the denitrification effect.
