Problems solved by technology

[0004] In view of this, the present invention aims at the deficiency of removing the moisture of heavy metal-enriched plants by airing, and proposes a heavy metal-enriched plant treatment system without airing, so as to ensure that the drying process of plants will not be affected by the climate and will not be released into the environment. Release toxic and harmful substances while improving the drying efficiency of plants

Embodiment Construction

[0022] Hereinafter, the present invention will be further described in detail through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present invention will become clearer. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Such as Figure 1-2 As shown, the heavy metal-enriched plant treatment system of this embodiment includes an incinerator 1, a pretreatment tank 2, a two-stage spray tower 3, and a bag filter 4. The exterior of the pretreatment tank is covered with a layer of insulation material to ensure the insulation effect and save energy. The pretreatment tank is provided with an air outlet 201 at the top, an air inlet 203 and an ash hopper 204 at the bottom, and a multi-layer support net 202 is provided in the pretreatment tank. The support net is sealed with the pretreatment tank or assembled by sliding The way of th...

Abstract

The invention discloses a heavy metal enriching plant treatment system. An incinerator, a pretreatment box, two levels of spraying towers and a bag-type dust collector are included. An air outlet is formed in the top of the pretreatment box, the bottom is provided with an air inlet and an ash bucket, and a multi-layer supporting net is arranged in the pretreatment box. The air outlet end of the incinerator communicates with the air inlet of the pretreatment box through a pipeline. An air outlet of the pretreatment box communicates with the air inlet end of the first-level spraying tower through a pipeline. The air outlet end of the first-level spraying tower communicates with the air inlet end of the second-level spraying tower through a pipeline, and the air outlet end of the second-levelspraying tower communicates with the air inlet end of the bag-type dust collector. According to the plant treatment system of the structure, plants can be rapidly dried, toxic and harmful substancescannot be released to the environment, and meanwhile the drying efficiency is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of incineration of heavy metal-enriched plants, in particular to a heavy metal-enriched plant processing system. Background technique [0002] Agricultural non-point source pollution is an important factor affecting my country’s food safety. Remediation of farmland contaminated by moderate to light heavy metals has become the focus of attention of the whole people. Among them, phytoremediation methods are widely used because of their low cost, strong applicability, and ability to completely separate heavy metals from the soil. [0003] Plants that are rich in heavy metals need to be treated, and incineration is an effective means of reduction. However, the enriched plants have a high moisture content, which can reach more than 95wt.%, so they cannot be burned directly and need to remove water. Drying is currently the most commonly used method, but there are several shortcomings in drying to remove water: First, i...
