The specific embodiment
In the mine air-lack mash gas separator as shown in Figure 1, gas pump station 1 is connected with the input of a multistage gas eliminator by gas input channel 4, and the output of multistage gas eliminator is connected with gas output channel 27, and above-mentioned multistage gas eliminator comprises the gas separation container that connects successively by the gas carrier pipe more than two.As a kind of preferred, the number of the gas separation container that multistage gas eliminator comprises is three, namely in structure as shown in Figure 1, multistage gas eliminator comprises first order gas separation container 7, second level gas separation container 15, with third level gas separation container 23, and be equipped with the middle part air inlet port that is positioned at the chamber wall middle part, the gas outlet, top that is positioned at the gas outlet, bottom of chamber wall bottom and is positioned at container top on each gas separation container.Gas pump station 1 is connected with the middle part air inlet port 6 of first order gas separation container 7 by gas input channel 4, the gas outlet, top 8 of first order gas separation container 7 is connected with the middle part air inlet port 14 of second level gas separation container 15 by gas carrier pipe 13, the gas outlet, top 16 of second level gas separation container 15 is connected with the middle part air inlet port 22 of third level gas separation container 23 by gas carrier pipe 17, and the gas outlet, top 24 of third level gas separation container 23 is connected with gas output channel 27.
In addition, at the gas outlet, bottom 11 of first order gas separation container 7, the gas outlet, bottom 20 of second level gas separation container 15,26 places, gas outlet, bottom of third level gas separation container 23, and on gas input channel 4 and gas output channel 27, all can also add control valve, control valve 5 as shown in Figure 1, control valve 12 and control valve 29.Control valve plays the effect of one way valve and control gas flow simultaneously, thereby can prevent gas backstreaming in the gas course of conveying, and can real-time adjusting gas flow.
When above-mentioned mine air-lack mash gas separator work, ventilation air gas enters first order gas separation container 7 through gas pump station 1 and gas input channel 4, because the main component in the gas is methane, its relative density to air is 0.554, air is lighter relatively, so after ventilation air gas enters into first order gas separation container 7, gas wherein (being mainly methane) just can be assembled from trend container top, thereby the gas density in the container upper gas is improved, and this portion gas is through the gas outlet, top 8 of first order gas separation container 7, the middle part air inlet port 14 of gas carrier pipe 13 and second level gas separation container 15 enters second level gas separation container 15, the gas of remainder is then discharged by the gas outlet, bottom 11 of first order gas separation container 7, has so just realized the preliminary separating-purifying to gas; According to this principle, repeat the above-mentioned course of work in that second level gas separation container 15 and third level gas separation container 23 are interior, thereby realized gas is carried out step by step separating-purifying, so that the gas density behind the separating-purifying is more and more higher, and the methane gas of the higher concentration that finally obtains is through 27 outputs of gas output channel.The gas that this part gas density is higher may be output to the gas accumulator plant, perhaps carries out other processing and application.
As further improvement, for above-mentioned mine air-lack mash gas separator, the gas outlet, bottom 26 of third level gas separation container 23 wherein can further be connected with the middle part air inlet port 18 of second level gas separation container 15 by gas carrier pipe 25 and one way valve 21, and the gas outlet, bottom 20 of second level gas separation container 15 can further be connected with the middle part air inlet port 9 of first order gas separation container 7 by gas carrier pipe 19 and one way valve 10.Wherein, middle part air inlet port 18 can be same air inlet port with middle part air inlet port 14, also can be two different air inlet ports in the middle part of the chamber wall that all is opened in second level gas separation container 15; In like manner, middle part air inlet port 9 can be same air inlet port with middle part air inlet port 6, also can be two different air inlet ports in the middle part of the chamber wall that all is opened in first order gas separation container 7; 21 on one way valve 10 and one way valve allow gas unidirectional to flow, thereby prevent gas backstreaming in the gas course of conveying.In the course of work in this case, the gas of discharging through the gas outlet, bottom 26 of third level gas separation container 23 will be recycled in the second level gas separation container 15, the gas of discharging through the gas outlet, bottom 20 of second level gas separation container 15 is recycled to again in the first order gas separation container 7, thereby carry out separating-purifying repeatedly, guarantee effectively to reclaim the more gas energy, and reduce the atmosphere pollution that discharging causes.
Need to prove, according to needed different gas densities, the number of the gas separation container that above-mentioned multistage gas eliminator comprises can determine flexibly that the connection between a plurality of gas separation containers then can be carried out according to the method for attachment that foregoing is set forth.
As the again improvement in a step, as shown in Figure 1, on the gas input channel 4 of mine air-lack mash gas separator and gas output channel 27, also can be respectively equipped with thin water smoke technological processing for explosion protection feature device 2 and thin water smoke technological processing for explosion protection feature device 30.Thin water smoke technological processing for explosion protection feature device 2 is identical with the structure of thin water smoke technological processing for explosion protection feature device 30, all according to national security production industry standard, design according to coal mine light concentration mash gas and thin water smoke mixed security conveying device technical specification, mainly formed by gas conveyer tube, water fog generator, water seal fire arrestor, coal mine gas gas conveyer tube Steel Bellows spark arrester, gas safety diffusion valve, dehydrator, recirculated water feed system, control system etc.By thin water smoke technological processing for explosion protection feature device 2 and thin water smoke technological processing for explosion protection feature device 30 are installed, can prevent in the gas transfer passage, producing burning things which may cause a fire disaster and gas is blasted in course of conveying, thereby effectively guarantee security performance.
As further improving, as shown in Figure 1, on the gas input channel 4 of mine air-lack mash gas separator and gas output channel 27, also can be respectively equipped with firedamp sensor 3 and firedamp sensor 28, to detect flow and the gas density of the mine air-lack mash gas before and after the separating-purifying.
The above has done detailed description to the preferred specific embodiment of the utility model and embodiment by reference to the accompanying drawings, but the utility model is not limited to the above-described embodiment and examples, in the ken that those skilled in the art possess, can also make without departing from the concept of the premise utility various variations.
