Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to a heavy metal particle adsorption treatment mechanism in garbage incineration flue gas. Background Art

[0002] Heavy metals in garbage will volatilize and attach to submicron particles as the temperature rises during the combustion process, and then enter the atmosphere to cause harm to the ecological environment and human body. Today's flue gas impurities are mostly removed by wet spraying, bag dust removal or other flue gas capture devices, but the collection efficiency of metal particles is not high.

[0003] After searching, the application with patent publication number CN113813731A discloses a heavy metal particle adsorption and treatment system in waste incineration flue gas, including an adsorption device body, the air inlet end of the adsorption device body is fixedly connected to a horizontal pipe, the inner wall of the horizontal pipe is fixedly connected to a filter, the front of the horizontal pipe is fixedly connected to a vertical pipe, and the horizontal pipe is communicated with the vertical pipe, the front of the vertical pipe is provided with an air inlet, the inner cavity of the vertical pipe is provided with a separation component, and the inner cavity of the horizontal pipe is provided with a cleaning component, a large amount of smoke particles in the flue gas are separated by the cooperation of the separation component and the filter, so that the adsorption device body can efficiently adsorb heavy metal particles.

[0004] However, due to the setting of the adsorption device body, the flue gas enters through the air inlet. Since the temperature of the newly generated flue gas is high, the high-temperature flue gas is directly adsorbed by the adsorption device, which can easily affect the use effect and life of the adsorption device. At the same time, since the smoke and heavy metal particles are separated by the separation component and the filter, the effect of the adsorption device on adsorbing heavy metals is increased, resulting in poor adsorption effect of the adsorption device body.

[0005] Therefore, we proposed a mechanism for adsorbing and treating heavy metal particles in waste incineration flue gas. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a heavy metal particle adsorption treatment mechanism in waste incineration flue gas, which solves the problems that the prior device cannot cool the flue gas and has a poor adsorption effect on heavy metal particles.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a heavy metal particle adsorption and treatment mechanism in waste incineration flue gas, comprising a flue gas cylinder, the top surface of which is equipped with a treatment box;

A refrigerator connected to the inside of the cooling plate is fixedly installed inside the processing box, and the top surface of the cooling plate is provided with evenly distributed and through cooling holes;

[0009] The top surface of the processing box is equipped with an adsorption tube opposite to and connected to the cooling hole. The adsorption tube is made of nano metal oxide material. The top surface of the processing box is equipped with a protective cover with matching specifications. The top surface of the protective cover is fixedly equipped with an exhaust port connected to the adsorption tube.

[0010] Preferably, the radius of the flue gas tube gradually decreases from top to bottom, which can increase the contact area between the cooling plate and the flue gas and improve the cooling efficiency and effect.

[0011] Preferably, the bottom surface of the flue gas cylinder is equipped with a drain port, which can facilitate the discharge of water in the flue gas cylinder.

[0012] Preferably, a filter plate made of activated carbon material is installed on the inner wall of the exhaust port, so that the smoke can be filtered to prevent large particles of dust from entering the interior and affecting its use.

[0014] Preferably, the thickness of the cooling plate is 10 cm, which can improve the cooling effect of the cooling plate on the flue gas.
