Waste gas heavy metal adsorption device for cracking furnace

Abstract

The invention discloses a waste gas heavy metal adsorption device for a cracking furnace. The waste gas heavy metal adsorption device comprises a flue gas collecting device, a first high temperature furnace, a second high temperature furnace, a dehumidifier, an activated carbon adsorption device and a microprocessor, which are sequentially connected through an airflow pipeline, wherein an electromagnetic valve and an air extracting pump are respectively arranged on the airflow pipeline among the flue gas collecting device, the first high temperature furnace, the second high temperature furnace and the dehumidifier; a first temperature control device connected with the microprocessor is arranged in the first high temperature furnace; a second temperature control device connected with the microprocessor is arranged in the second high temperature furnace, and a plurality of adsorption nets adsorbing heavy metal in waste gas are paved in the second high temperature furnace; a filtering film of which the shape is matched with the shape of the tail end of an outlet is arranged at the tail end of the outlet of the second high temperature furnace. The adsorption efficiency for the heavy metal is high, and secondary pollution can be avoided, so that the waste gas heavy metal adsorption device has strong practicality.

Description

technical field [0001] The invention is designed in the field of environmental protection, and specifically relates to a heavy metal adsorption device for cracking furnace waste gas. Background technique [0002] With the advancement of science and technology and the rapid development of the economy, the environmental problems caused by solid waste have attracted more and more attention. At present, most solid wastes are treated by cracking furnaces. During the treatment process, although there are many toxic and harmful substances in the waste gas generated by the cracking furnace, the waste gas also contains many heavy metal substances. How to treat the waste gas The recycling of heavy metals in the environment has always been the focus of research. [0003] However, the waste gas heavy metal adsorption device in the related art has the following technical problems: in the process of heavy metal adsorption, due to the insufficient treatment of the newly generated waste ga...

Problems solved by technology

[0003] However, the waste gas heavy metal adsorption device in the related art has the following technical problems: in the process of heavy metal adsorption, due to the insufficient treatment of the newly generated waste gas, the waste gas discharged into the environment is likely to cause secondary pollution, and then cause harm to the human body; in addition, Due to the interference of other toxic and harmful substances in the exhaust gas, the adsorption of heavy metals is not complete, which affects the recovery efficiency and does not fully achieve the purpose of heavy metal recycling.
