A kind of pretreatment unit of controlling soil moisture content
Technical field
The utility model relates to soil remediation engineering field, particularly a kind of pretreatment unit of controlling soil moisture content.
Background technology
Along with urbanization and economic developing rapidly, the pollution level of China's soil is constantly aggravated, and pollution range sharply expands, and soil environment situation totally allows of no optimist.Soil Pollution Investigation communique > > investigation result display section, the < < whole nation in 2014 Soils In The Region heavy contamination, arable soil environmental quality causes anxiety, industry and mining abandoned land soil environment outstanding problem.And pollution in soil is very large to people's health effect, therefore, in order to solve the problems such as soil pollution and agricultural product security, a large amount of contaminated soils need to be repaired and administer.
The content of soil moisture is the pith of soil physico-chemical property, and soil moisture content is the basic data that must predict in soil remediation utilization process, is the prerequisite of calculating other compositions, is also one of factor directly affecting repairing effect.Although soil has the ability of certain sticking moisture, the content of the soil water is often to change, and adds the variation of construction site and Changes in weather factor etc., very necessary to the control of soil moisture content.At present, no matter be laboratory or engineering site, the auxiliary facility of soil remediation is all incomplete, more there is no the device of complete control soil moisture content.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of pretreatment unit of controlling soil moisture content, and energy Real-Time Monitoring soil moisture is also controlled its moisture content, to improve the convenient validity of postorder soil remediation technology application.
For achieving the above object, the utility model has adopted following technological means:
A kind of pretreatment unit of controlling soil moisture content, comprise and process storehouse, control panel, agitator, extraction pipeline, water storage tank, storage soil case and gas adsorption chamber, process in storehouse and be provided with agitator, agitator is provided with humidity sensor probe, the top of processing storehouse connects extracts pipeline, water storage tank, store native case and gas adsorption chamber respectively with extract pipeline and be connected, process storehouse one side and connect into native extraction pump, process storehouse opposite side and connect the extraction pump of being unearthed.
Described control panel is located on the outer wall of processing storehouse.
Described extraction pipeline is toroidal processing inside, storehouse.
The indoor activated carbon filtration plate that is provided with of described gas absorption, top, chamber is provided with aiutage.
Compared with prior art, the beneficial effects of the utility model are:
1) this device can be found out the moisture situation of soil, thereby regulation and control soil moisture content is to preset value, promotes the validity of soil remediation; 2) the accessory cost of device is lower, uses extensively, installs easy and simple to handle; 3) gas absorption chamber can effectively reduce or remove poisonous and harmful volatile organic matter in soil, to environment non-secondary pollution.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1-processes storehouse, 2-control panel, 3-agitator, 4-humidity sensor probe, 5-and extracts pipeline, 6-water storage tank, 7-and store native case, 8-gas absorption chamber, 9-and enter native extraction pump, 10-be unearthed extraction pump, 11-activated carbon filtration plate, 12-aiutage.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model specific embodiment is described:
See Fig. 1, it is a kind of structural representation of controlling the pretreatment unit embodiment of soil moisture content of the utility model, comprise processing storehouse 1, control panel 2, agitator 3, extract pipeline 5, water storage tank 6, store native case 7 and gas adsorption chamber 8, process in storehouse 1 and be provided with agitator 3, agitator 3 is provided with humidity sensor probe 4, the top of processing storehouse 1 connects extracts pipeline 5, water storage tank 6, store native case 7 and gas adsorption chamber 8 respectively with extract pipeline 5 and be connected, process storehouse 1 one sides and connect into native extraction pump 9, process storehouse opposite side and connect the extraction pump 10 of being unearthed.
Control panel 2 is located on the outer wall of processing storehouse 1.Extracting pipeline 5 is toroidal processing 1 inside, storehouse.In gas absorption chamber 8, be provided with activated carbon filtration plate 11, top, chamber is provided with aiutage 12.
In control panel 2, be provided with switch for control device work, humidity sensor, for controlling agitator 3, water storage tank 6, store native case 7 and extract the controller of pipeline 5.
During device work, the Polluted Soil that will repair is sent in processing storehouse 1 by entering native extraction pump 9, agitator 3 starts to stir, water cut value in the real-time sensing chamber of humidity sensor probe 4 in soil, according to data or technological requirement control panel 2, control respectively water storage tank 6 water inlets or store native case 7 and enter soil, or be pumped to gas absorption chamber 8 from extracting pipeline 5, escaping gas is overflowed from aiutage 12 after activated carbon filtration plate 11 is processed, finally start the extraction pump 10 of being unearthed, the soil that reaches default moisture content is discharged.
