Post-treatment recovery system for heavy metal-enriched plants

Abstract

The invention discloses a heavy metal enriched plant post-treatment recovery system which comprises an incinerator and a transportation device, a drying cavity, an incineration cavity and an ash collection cavity are sequentially arranged in the incinerator from top to bottom, the drying cavity and the incineration cavity are separated by an inclined plate and a baffle door, and the incineration cavity and the ash collection cavity are separated by a fire bar; a feeding port is reserved between the lower end of the inclined plate and the inner side wall of the incinerator, the blocking door is located below the feeding port, blocks the feeding port and is opened intermittently, the outer end of the blocking door is hinged to the side wall of the incinerator, and the inner end of the blocking door is attached to the lower side face of the inclined plate. The plant treatment efficiency can be improved, and toxic and harmful substances can be prevented from being released when the plants are aired.

Description

technical field [0001] The invention relates to the technical field of heavy metal plant treatment, in particular to a post-processing recovery system for enriching heavy metal plants. Background technique [0002] At present, phytoremediation is generally adopted for land contaminated by heavy metals. After plants absorb heavy metals in the soil, they are generally treated by incineration. However, due to the high water content of plants, it cannot be directly incinerated, and it needs to be dried first. Incineration treatment can only be carried out after moisture, but this will not only reduce the efficiency of processing plants enriched with heavy metals, but also be affected by the weather, and plants may also release some toxic and harmful substances when they are dried. In order to avoid the above Problem The present invention provides a post-processing recovery system for enriching heavy metal plants. SUMMARY OF THE INVENTION [0003] The purpose of the present in...

[0002] At present, phytoremediation is generally used for land polluted by heavy metals. After plants absorb heavy metals in the soil, they are generally treated by incineration. However, due to the high moisture content of plants, they cannot be directly incinerated. They need to be dried out first. Incineration can only be carried out after moisture, but this will not only reduce the efficiency of processing heavy metal-enriched plants, but also be affected by the weather, and the plants may release some toxic and harmful substances when drying. In order to avoid the above Problem The present invention provides a post-treatment recovery system for heavy metal-enriched plants
