Abstract
The utility model discloses a cooling system of an underground gas drainage pump used for a coal mine, which comprises an underground water source, a water inlet valve, a water-break protector and a steam and water separator which are sequentially connected with the underground water source, wherein one end of the gas drainage pump is connected with the water-break protector, and the other end of the gas drainage pump is connected with the steam and water separator. The system also comprises a cooling water tank, a cooling tower and a circulating water tank, wherein the cooling tower is arranged under the cooling water tank, and the circulating water tank is arranged under the cooling tower; a cooling water pipe connected with the underground water source is arranged in the cooling water tank, the upper part of the cooling water tank is connected with a water outlet valve of the steam and water separator through a pipeline, the lower part of the cooling water tank is connected with the cooling tower through a pipeline, and cooling water falls into the circulating water tank after being cooled by the cooling tower; and a submersible pump is arranged in the circulating water tank and is connected with the water-break protector through a control valve. When the cooling system of the underground gas drainage pump with the structure works, an enclosed circulation process of water is formed in the whole system, no waste water is discharged, and water resources are saved.
Description
Technical field
The utility model relates to a kind of colliery fire damp extraction pump cooling system; especially relate to a kind of water source, down-hole that comprises; the fire damp extraction pump cooling system of inlet valve, no water protector and the steam-water separator that links to each other successively with this water source, down-hole; one end of gas suction pump links to each other with no water protector, and the other end links to each other with steam-water separator.
Background technique
The colliery carries out can producing methane gas in the recovery process of coal at present, exist serious potential safety hazard when methane gas reaches finite concentration, so the colliery all is provided with the drawing-off gas device.The equipment of most critical is gas suction pump in the drawing-off gas device, long self can the heating of gas suction pump operating time, temperature raises, this equally also can bring potential safety hazard to the working site, exist the possibility that makes methane gas burning even blast, therefore must the gas suction pump in the drawing-off gas device be cooled off.Method commonly used at present is to utilize the water source, down-hole that gas suction pump is cooled off; the water source, down-hole passes through inlet valve; no water protector links to each other with gas suction pump; the other end of extraction pump links to each other with steam-water separator; methane gas and water are discharged in the steam-water separator; methane gas enters the system pipeline of methane gas tapping equipment; water is then discharged by the steam-water separator bottom; the water of discharging is discharged to sump by submersible pump again; and then be discharged to ground; the problem that this gas suction pump cooling system exists is will waste great amount of water resources in to the gas suction pump cooling procedure.
The model utility content
The technical problems to be solved in the utility model provides a kind of colliery fire damp extraction pump cooling system, the discharging that can not produce waste water when using this system that gas suction pump is cooled off.
For solving the problems of the technologies described above, the utility model colliery fire damp extraction pump cooling system, comprise the water source, down-hole, the inlet valve, no water protector and the steam-water separator that link to each other successively with this water source, down-hole, one end of gas suction pump links to each other with no water protector, and the other end links to each other with steam-water separator, and this system also comprises cooling water tank, cooling tower and cyclic water tank, cooling tower places the below of cooling water tank, and cyclic water tank places the below of cooling tower; Described cooling water tank inside is provided with the water-cooling tube that links to each other with the water source, down-hole, the top of this cooling water tank links to each other with the outlet valve of described steam-water separator by pipeline, the bottom of cooling water tank links to each other with cooling tower by pipeline, and cooling water falls in the described cyclic water tank after described cooling tower cooling; Be provided with submersible pump in the described cyclic water tank, this submersible pump links to each other with no water protector by control valve.
Adopt above-mentioned colliery fire damp extraction pump cooling system; start-up control valve when work; close inlet valve; water is extracted out by cyclic water tank through submersible pump; by pipeline through control valve; the no water protector of flowing through arrives gas suction pump again; through steam-water separator; methane gas enters the system pipeline of methane gas tapping equipment; water is then discharged by the outlet valve of steam-water separator bottom and is entered cooling water tank; enter cooling tower again and be back to cyclic water tank at last; the fire damp extraction pump cooling system of this formation water when work has formed a closed-circuit process in whole system, does not have waste water to discharge, and has saved water resources.
