Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of manual, is used to explain the present invention with embodiments of the invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the front view of colliery extraction borehole gas-water separation syndeton embodiment of the present invention;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is arranged at the stereogram of production face for colliery of the present invention extraction borehole gas-water separation syndeton.
The specific embodiment
For making the object of the invention, technical scheme and advantage clearer; To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention carried out clear, intactly description, obviously; Described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The embodiment of colliery of the present invention extraction borehole gas-water separation connection method; Be with the outermost end that is connected extraction borehole as the T type equal tee of moisture trap in this connection method; When connecting, make T type equal tee and extraction borehole reach good sealing, prevent the situation of leaking, leaking gas and take place.Describe for the ease of hereinafter, regulation T type equal tee is in the logical section of two on the same straight line and is respectively first logical and second logical here, and the logical section of another one is threeway.In this syndeton, be that threeway is connected with extraction borehole, be connected the back with extraction borehole and guarantee first logical and second logical being on the vertical state in threeway.Have only first logical and second logical being on the vertical state, the mixture that just is beneficial to the gas of discharging in the extraction borehole and water is realized separation automatically under the effect of gravity.Stipulate that it is exhaust opening above first logical being positioned at, it is leakage fluid dram below second logical being positioned at.Because gas proportion is less, add the negative pressure of extraction in addition, gas can lead to the discharge that enters into above being arranged on via first rapidly, and finally enters into the extraction pipeline.And water can be under the effect of gravity, via second perfectly straight the connecing in the header that downward inflow is arranged on the below.
Discharge that in the extraction borehole gas-water separation connection method of above-mentioned colliery, adopts and header all are made up of the tube connector and the T type reducer tee that connect in order.And T type equal tee can connect a plurality of T type equal tees as a part that is connected the gas-water separation pipeline between discharge and the header in every gas-water separation pipeline, and per two adjacent T type equal tees are connected with tube connector.And the threeway of each T type equal tee all is connected with corresponding extraction borehole.Between discharge and header, many identical gas-water separation pipelines can be set.
In order to reach the purpose of further raising extraction effect; Adopt the internal diameter of the internal diameter of discharge greater than the gas-water separation pipeline; Isolated gas imports in the bigger discharge of same internal diameter through many less gas-water separation pipelines of internal diameter, has reached the requirement of big flow extraction.
In order to reach the purpose of further raising drainage effect; Adopt the internal diameter of the internal diameter of header greater than the gas-water separation pipeline; Isolated water imports in the bigger header of same internal diameter through many less gas-water separation pipelines of internal diameter, has reached the requirement of big flow draining.
Like Fig. 1,2, shown in 3, the embodiment of colliery of the present invention extraction borehole gas-water separation syndeton comprises discharge 4 that is positioned at the top and the header 5 that is positioned at the below, discharge 4 and header 5 average level settings, and discharge 4 is parallel to each other with header 5.Between discharge 4 and header 5, be connected with the gas-water separation pipeline of vertical setting; Has the T type equal tee 1 that uses as moisture trap in the gas-water separation pipeline; The threeway of T type equal tee 1 is the lateral openings of moisture trap, and the 3rd be common to crag 9 on the exploitation boring 8 of offering be connected.One end of discharge 4 is cecums, and the other end connects extraction pipeline 7 and carries out extraction.One end of header 5 equally also is a cecum, and the other end is connected with a tailrace 6 through connecting line 10, and tailrace 6 can be automatic tailrace, also can be manual tailrace.On connecting line 10, be connected with a valve 11; When tailrace 6 discharges water; Close above-mentioned valve, prevent that gas from entering in the tailrace 6 when discharging water, and be drained into the mining operations district through tailrace 6; Avoided the invar stone to cross tailrace 6 and entered into the mining operations district, the problem that causes mining operations district gas density to exceed standard occurs.
The gas-water separation pipeline is made up of T type equal tee that alternately connects in order 1 and tube connector 3, and this T type equal tee 1 is welded by the identical pipe fitting of caliber.Discharge 4 all is made up of T type reducer tee that alternately is connected in order 2 and tube connector 3 with header 5.For the ease of describing, regulation T type reducer tee 2 is in the logical section of two on the same straight line and is respectively first logical and second logical here, and the logical section of another one is threeway.Wherein, first of T type reducer tee is logical identical with second internal diameter that lead to and greater than the internal diameter of threeway.And the internal diameter of the threeway of T type reducer tee 2 equates with the internal diameter of T type equal tee 1.So just formed the internal diameter of the internal diameter of discharge, further improved the extraction effect greater than the gas-water separation pipeline; The internal diameter of header has further improved drainage effect greater than the internal diameter of gas-water separation pipeline.
After adopting this colliery extraction borehole gas-water separation syndeton, the water of discharging in the extraction borehole promptly is separated with gas before getting into the extraction pipeline, avoids entering into the extraction pipeline, thereby makes that the extraction system can economic, efficient, safe operation.Simultaneously, this syndeton is simple in structure, is easy to install, and cost is low.
What should explain at last is: above embodiment is only in order to explaining technical scheme of the present invention, but not to its restriction; Although with reference to previous embodiment the present invention has been carried out detailed explanation, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of the essence disengaging various embodiments of the present invention technical scheme of relevant art scheme.
