Description
Technical field
The utility model belongs to mineral products leaching technical field, is specifically related to a kind of pour to strain to test device of gangue.
Background technology
Gangue is total to lower, harder than the coal black gray expandable rock of consedimental a kind of carbon content with coal in coalification course, and usually in thin layer, association is in coal seam or coal seam is pushed up, base plate.Gangue is being mined and the mine solid-state castoff of a large amount of discharge in coal washing process, and its discharge capacity is about 15% ~ 20% of colliery raw coal output, is one of maximum trade waste of the current annual emissions of China and cumulative stock.China's state-owned coal mines existing waste dump more than 2000 seat, accumulating amount more than 7,000,000,000 tons (accounting for more than 40% of Chinese industrial solid-state castoff total emission volumn), floor area is about 70km
2, also will discharge gangue 1.5 ~ 2.0 hundred million tons every year.Gangue and deposit thereof not only cause the waste of resource, and bring great harm to mine entironment and human survival.Solid waste huddle leave about, contaminated wastewater river, atmospheric pollution are serious, objectionable impurities does not obtain fully degraded etc., the huge direct property loss all caused, and cannot estimate especially the consequential damages of mine geology environment, particularly more huge to the harm of water and soil, its pollution also has chronicity, disguise, nonreversibility, and pole refractory is managed.Therefore, carry out indoor gangue pour to strain to test, the mechanism of action that leaching causes water and soil pollution is there is in Study on Coal spoil under rainfall, explore the release and transport rule of pollution factor in this leaching process, for developing contaminant degradation instrument further or taking corresponding engineering measures of preventing and protecting, solve mining area solid-state castoff and stack the water and soil pollution problem caused, have important theory and realistic meaning.
At present, the leaching mode that most researchers adopts mainly contains the dynamic leaching of unsaturation state and leaching two kinds of modes of saturated mode.Wherein, the leaching of saturated mode is easy to realize, solid-liquid contact relation is clear and definite, but under in test, gangue is in saturated immersion operating mode all the time, be not inconsistent with the gangue leaching process under real condition of raining, scholar is had to regard this immersion way the limiting case of dynamic leaching as, but the material of dynamic leaching is separated out releasability and is greater than immersion way also to have contrast test to show, the two inherent mechanism is not identical, therefore, when conclusion (of pressure testing) under saturated immersion way is extended to practical application, its applicability need textual criticism.。
The leaching mode of unsaturation state is closer to the leaching situation of reality, the conclusion drawn and rule have stronger practical guided significance, a lot of scholar adopts this leaching mode to carry out lot of experiments research, and the gangue leaching device adopted connects to form primarily of water supply part, aqueduct and leaching post.Wherein, water supply part mostly is the instrument and equipments such as water supply bottle (case), geneva bottle; Aqueduct is single water pipe, and the conduit mouth in part leaching device is connected with shower nozzle equipment; Leaching post is column type organic glass or the plastic pipe of different size, and by arranging funnel in pipe bottom or discharging leachate at side-wall hole.During test, be connected by aqueduct with supply equipment, and water delivering orifice or shower nozzle be fixed on directly over leaching post, open Water supply switch valve, aqueduct water outlet, carry out leaching to spoil in leaching post, timing is got leachate and is carried out relevant item detection, completes different tests content.
Based on the gangue leaching device of the dynamic leaching mode of above-mentioned unsaturation state, the technical issues that need to address are simulated rainfall conditions mainly, carries out even leaching to gangue sample.Different researchers adopt difference between leaching device, be mainly the size of leaching post.The leaching post of different-diameter has respective pros and cons, and the leaching pipe (≤Φ 3cm) of small diameter is abundant to the leaching of spoil post, but can only study small particle diameter spoil sample, and test condition restriction is comparatively large, is not inconsistent with real leaching situation, larger-diameter leaching post (>=Φ 5cm) can carry out the test of Large stone spoil sample, but supply water owing to adopting single aqueduct, its wetted perimeter is less, cause spoil post surface incomplete with liquid comes into contact, the object of spoil being carried out to uniform rainfall leaching cannot be realized, though certain wetted area can be increased by connecting shower nozzle, but because the rainfall intensity of simulation is less, more flow in test is arranged on and is less than in the scope of 10ml/min, flow rate of water flow in aqueduct is very low, make the actual spray effect of shower nozzle unsatisfactory, and quartz sand layer or degreasing cotton layer is laid on spoil post surface, the effect that raising spoil sample is occurred under condition of raining to for eluviation homogeneity is also very limited.
In sum, the existing gangue leaching device based on unsaturation state leaching mode, unsatisfactory to the analog simulation degree of actual condition of raining, main Problems existing is that the way of supplying water of single aqueduct limits the wetted area of rainwater to spoil post surface, leaching column diameter is larger, and this problem is more obvious; And leaching column diameter less time, create again the problem cannot tested Large stone spoil, being thus difficult to simulating reality condition of raining to gangue sample carries out even leaching, is difficult to simulate the leaching process of gangue under rainfall more really.
