The in-situ repairing device of a kind of shallow-layer face source organic polluted soil
The utility model relates to the reparation field of organic polluted soil, particularly the in-situ repairing device of a kind of shallow-layer face source organic polluted soil.
The reparation of contaminated soil exists showering and original position to repair two kinds of modes at present, after current showering excavates contaminated soil often with chemistry or physical method clean, burning disposal or heat treatment etc.; Showering processing cost is high, and easily causes secondary pollution; In the face of the processing of some contaminated soils that cannot move, often helpless; Original position in garden is repaired ubiquity problem: because the garden contaminated soil that applies of chemical fertilizer and agricultural chemicals mainly concentrates on shallow-layer, and the pollutant of rehabilitating soil shallow-layer emphatically; Industrial crops in the garden having put into production had better not be moved, and in repair process, can not affect existing production; The pharmaceutical quantities adding and sphere of action needs are controlled, avoid causing reparation imperfection or the excessive secondary pollution that causes environment.
Summary of the invention
The purpose of this utility model is to provide the in-situ repairing device of a kind of shallow-layer face source organic polluted soil, be intended to for being subject to the different soil of the degree of non-point source pollution in garden, utilize this device can effectively control the sphere of action of medicament, avoided the blind area of repairing, and the cost of showering is high, the technical problem that easily causes secondary pollution.
The technical solution of the utility model is:
For solving above-mentioned technical problem, the in-situ repairing device of shallow-layer face of the present utility model source organic polluted soil comprises fluid reservoir, vavuum pump, pressure-bearing pipe network, flow control valve and injection part, described vavuum pump is connected with fluid reservoir by pipeline, described flow control valve is arranged between pressure-bearing pipe network and vavuum pump, described pressure-bearing pipe network bottom is provided with equally distributed 3 above injection part, described injection part comprises telescoping tube, injection orifice and injection termination, described telescoping tube is enclosed within on pipeline, described injection orifice is evenly distributed on pipeline, described injection termination is located at pipe end.
Further, described telescoping tube end is provided with mud guard, and described mud guard is connected with telescoping tube.
Further, described mud guard is circular or square, and the diameter of section of described telescoping tube is less than the width of mud guard.
Further, the length that described injection orifice distributes on pipeline is less than or equal to the length that telescoping tube upwards stretches.
Adopt after said structure, by vavuum pump and flow control valve, can control the flow rate flow of solution, simultaneously, injection part is inserted to the contaminated soil of different depth, injection solution, can reach good original position repairing effect, also can according to the area of wanted rehabilitating soil lay flexibly pressure-bearing pipe network W1, W2 ... Wn, with this, control as required radius and the scope of repairing, avoided reparation blind area.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural scheme of mechanism of injection part 4.
Fig. 3 is the structural representation of flow control valve 5.
In figure: 1 is fluid reservoir, 2 is vavuum pump, and 3 is pressure-bearing pipe network, and 4 is injection part, and 5 is flow control valve, and 6 is pipeline, and 41 is telescoping tube, and 42 is injection orifice, and 43 is mud guard, and 44 is injection termination, and 51 is by-pass cock.
The specific embodiment
As Fig. 1, shown in Fig. 2 and Fig. 3, the in-situ repairing device of shallow-layer face of the present utility model source organic polluted soil comprises fluid reservoir 1, vavuum pump 2, pressure-bearing pipe network 3, flow control valve 5 and injection part 4, described vavuum pump 2 is connected with fluid reservoir 1 by pipeline 6, described flow control valve 5 is arranged between pressure-bearing pipe network 3 and vavuum pump 2, described pressure-bearing pipe network 3 bottoms are provided with equally distributed 3 above injection part 4, described injection part 4 comprises telescoping tube 41, injection orifice 42 and injection termination 44, described telescoping tube 41 is enclosed within on pipeline 6, described injection orifice 42 is evenly distributed on pipeline 6, described injection termination 44 is located at pipe end, can guarantee that injection part 4 inserts soil effectively.
Further, described telescoping tube 41 ends are provided with mud guard 43, and described mud guard 43 is connected with 41 telescoping tubes, by the resistance between mud guard 43 and earth, drive telescoping tube 41 to move up, and with this, expose injection orifice 42.
Further, described mud guard 43 is circular or square, and the diameter of section of described telescoping tube 41 is less than the width of mud guard 43, like this, by increasing mud guard 43, increase resistance with the contact area of earth, make telescoping tube 41 can reach at the soil of various structures the flexible function that makes progress.
Further, the length that described injection orifice 42 distributes on pipeline 6 is less than or equal to the length that telescoping tube 41 upwards stretches, and can guarantee so effectively to control the quantity that injection orifice 42 exposes, thereby controls injection volume.
In addition, to quality comparatively loose repair time, also can only with flow control valve 5, realize the control of flow velocity and flow, by the by-pass cock 51 of flow control valve 5, realize the control of flow velocity and flow, thereby save the energy of use vavuum pump 2; When to quality, soil is repaired comparatively closely, can according to circumstances increase the quantity of vavuum pump 2, to improve the pressure that injects solution, to reach effective injection, meanwhile, can coordinate flow control valve 5, control uninterrupted; This apparatus structure is simple, is easy to dismounting and assembling, can effectively reduce use cost.
