Description
Technical field
The utility model belongs to soil remediation field, and what be specifically related to is a kind of pretreatment unit of heavy-metal contaminated soil.
Background technology
The mankind being in food chain top are placed in the ground of danger by soil pollution, the particularly heavy metal accumulation in vegetables, grain.And heavy metal contaminants poor mobility, holdup time in soil long, be not easily degraded by microorganisms, particularly seriously in the pollution course of heavy metal in soil system, there is the characteristics such as disguise, chronicity and irreversibility.Therefore the harm of heavy-metal contaminated soil brings tremendous influence to environment, human survival and economic development.Its effective improvement has become the important focus of home and abroad environment scientific research.
The restorative procedure of present heavy-metal contaminated soil is a lot, but the pretreatment in early stage is not concerned, often because Polluted Soil is too moist or too dry thus affect the repair rate of soil.
Summary of the invention
The purpose of this utility model is the above problem overcoming prior art existence, provides a kind of pretreatment unit of heavy-metal contaminated soil, automatically can regulate the moisture content of heavy-metal contaminated soil.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of pretreatment unit of heavy-metal contaminated soil, comprise feeding warehouse, the edge cover plate of described feeding warehouse arranges moisture content inductor, be used for detecting the moisture content of contaminated soil, the below of described feeding warehouse arranges weighing apparatus, described weighing apparatus is positioned at the top of conveyer, the soil of having weighed is delivered to after reative cell from the discharging of discharging Hatch Opening by conveyer, several spray equipments and air blast are set in described reative cell, described moisture content inductor connection control device, described control device controls the operation of all spray equipments and air blast, described spray equipment and described air blast are all arranged in reative cell, the moisture content that described moisture content inductor detects soil is on the low side or higher, the operation of spray equipment and air blast is decided again by control device, the waste gas produced in course of reaction is delivered to after absorbent charcoal adsorber filters by the aspiration pump outside reative cell and enters air again.
Optimize, described feeding warehouse is up big and down small truncated rectangular pyramids cavity.
Optimize, described conveyer is belt conveyor.
The beneficial effects of the utility model are:
The utility model is novel in design, and structure is simple, and by regulating the moisture content situation in contaminated soil, the humidity of Control pollution soil, the process for next step contaminated soil provides good condition, improves the repair rate of contaminated soil.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 overall structure schematic diagram.
Number in the figure illustrates: 1, feeding warehouse, 2, moisture content inductor, 3, weighing apparatus, 4, conveyer, 5, control device, 6, spray equipment, 7, air blast, 8, discharging bin, 9, aspiration pump, 10, absorbent charcoal adsorber.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Fig. 1, a kind of pretreatment unit of heavy-metal contaminated soil, comprise feeding warehouse 1, described feeding warehouse 1 is up big and down small truncated rectangular pyramids cavity, contaminated soil enters from described feeding warehouse 1, the below of described feeding warehouse 1 arranges weighing apparatus 3, contaminated soil is transported in reative cell by conveyer 4 after described weighing apparatus 3 is weighed, described conveyer 4 is belt conveyor, when belt runs, speed is slow, the edge cover plate of described feeding warehouse 1 arranges moisture content inductor 2, described moisture content inductor 2 connection control device 5, described control device 5 connects several spray equipments 6 and air blast 7, described spray equipment 6 and described air blast are arranged evenly and at intervals, if moisture content inductor 2 measure the moisture content of contaminated soil higher time, send data to described control device 5, by described control device 5 pairs of data analysis, feel the unlatching quantity of air blast and the rotating speed of opening time and air blast, during conveyer 4 pairs of contaminated soil transports, air blast above conveyer 4 runs, carry out air-dry to contaminated soil, soil is made to become dry, if moisture content inductor 2 measure the moisture content of contaminated soil on the low side time, same, moisture content inductor 2 sends data to control device 5, described control device 5 carries out data analysis, feel the startup quantity of spray equipment, the amount of running time and spraying liquid, spray equipment is to soil spraying liquid, carry out moistening to contaminated soil, make it to reach certain humidity, soil after air blast 7 and spray equipment 6 process, humidity to reach after certain standard from discharging bin 8 discharging, facilitates post-processed.Waste gas is delivered to absorbent charcoal adsorber 10 by the aspiration pump 9 outside reative cell by the waste gas produced in course of reaction, and gas enters in air after absorption again, avoids secondary pollution.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
