Description

Technical Field

[0001] The utility model belongs to the technical field of activated carbon feeding in garbage incineration plants, and in particular relates to an activated carbon powder feeding device. Background Art

[0002] Since dioxins are generated and emitted during the waste incineration process, in order to better remove heavy metals and dioxins, activated carbon is sprayed into the flue gas pipeline between the semi-dry reaction tower and the dust collector to adsorb heavy metals and dioxins, ensuring that the emission concentration of heavy metals and dioxins reaches the project emission index. Therefore, the activated carbon injection system plays a very important role in the flue gas treatment system, but the daily usage of activated carbon in small-scale waste incineration power plants is limited, and considering that long-term storage of activated carbon will absorb moisture and other substances in the air, causing problems such as hardening, it is generally considered to set up a small-volume activated carbon silo to store activated carbon, and use a manual feeding device to feed the silo.

[0003] When the activated carbon silo is loaded manually, an electric hoist or other lifting equipment is installed on the top of the silo to lift the material bag from the ground to the top of the silo before loading. One operator is required to tie the activated carbon bag on the ground and then operate the lifting equipment, while another operator needs to stand on the top of the silo to assist in dropping the suspended activated carbon bag into the silo. The main problem is the serious environmental pollution. The black powder of the activated carbon will fly everywhere, which not only affects the environment of the plant, but also threatens the health of the operators. On the other hand, at least two people must be guaranteed to operate on site. Utility Model Content
