Abstract
The utility model belongs to the technical field of power supply for coal mining equipment and particularly relates to an emergency power supply system for coal mining equipment. The emergency power supply system for the coal mining equipment is characterized in that a stop valve C and a pressure reducing valve are arranged on the outlet end of a gas storage tank, a stop valve B is arranged at one end of a pipeline, a pressure reducing valve is arranged at the other end of the pipeline, and the stop valve B is connected with a gas generator unit. The emergency power supply system for the coal mining equipment has the advantages that when power cut happens to a coal mine outside network, the standby emergency CNG (LNG) gas storage tank is opened, the gas generator unit of a mining gas power station is utilized for generating power to supply the power to a gas pumping pump or other mining equipment, so that the gas pumping pump or the other mining equipment can run normally.
Description
Technical field
The utility model belongs to coal mine equipment power supply technique field, is specifically related to the coal mine equipment emergency power supply system.
Background technology
The ordinary production in colliery be unable to do without the normal operation of equipment such as gas suction pump, main fan, after the external electrical network outage, the colliery has a power failure, for equipment such as gas suction pump on the ore deposit, main fan can be worked on, the guarantee downhole safety is produced, conventional method is to utilize the diesel-driven generator generating, and diesel generation power can reach more than the 1000KW, but it is excessive to purchase the investment of high-power diesel generator.In addition, utilize diesel power generation to make the circuit complexity, increased operation and maintenance cost.At present, country supports the gas electricity project, the gas that uses that is used to generate electricity is subsidized by consumption, and to punishing in the colliery of random emptying gas, and therefore, a lot of collieries are all own or introduce the partner and build gas electricity factory.For the colliery that has gas electricity factory, can utilize the gas electricity unit generation as emergency power supply system.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of small investment is provided, and utilizes the coal mine equipment emergency power supply system of gas electricity unit generation.
The technical scheme that its technical problem that solves the utility model adopts is: the coal mine equipment emergency power supply system, comprise that gas pumps pump 1, stop valve A 2, stop valve B 3, shutoff valve C 6, pipeline 4, reducing valve 5, gasholder 7 and gas electricity unit 8, it is characterized in that be provided with reducing valve 5 and shutoff valve C 6 at gasholder 7 ports of export, an end of pipeline 4 is provided with stop valve B 3, the other end is provided with reducing valve 5, and stop valve B 3 links to each other with gas electricity unit 8.
Described gasholder 7 can adopt movable type.
Described pipeline 4 can adopt fiber material pipeline, the convenient use.
The beneficial effects of the utility model are: when the colliery outer net has a power failure, open standby emergent CNG (LNG) gasholder, utilize the gas unit generation supply gas of gas electricity factory on the ore deposit to pump pump or other coal mine equipments, make it to run well.Make the gas electricity unit generation with CNG (LNG) gasholder, can save the investment of diesel-driven generator.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the structural representation of the utility model coal mine equipment emergency power supply system.
Among the figure: 1, gas is pumped pump, and 2, stop valve A, 3, stop valve B, 4, pipeline, 5, reducing valve, 6, shutoff valve C, 7, gasholder, 8, the gas electricity unit.
The specific embodiment
As shown in Figure 1, the coal mine equipment emergency power supply system that the utility model proposes comprises that gas pumps pump 1, stop valve A 2, stop valve B 3, shutoff valve C 6, pipeline 4, reducing valve 5, gasholder 7 and gas electricity unit 8 is characterized in that, be provided with shutoff valve C 6 and reducing valve 5 at gasholder 7 ports of export, one end of pipeline 4 is provided with stop valve B 3, and the other end is provided with reducing valve 5, and stop valve B 3 links to each other with gas electricity unit 8.
Described gasholder 7 can adopt movable type.
Described pipeline 4 can adopt fiber material pipeline, the convenient use.
Under the normal condition of not cutting off the power supply, stop valve A 2 opens, and stop valve B 3, shutoff valve C 6 are closed.Gas is pumped pump 1 through gas and is entered combustion power generation in the gas electricity unit 8.
Under the outer net powering-off state, stop valve A 2 closes, and stop valve B 3 and shutoff valve C 6 are opened.After compressed natural gas in the gasholder 7 (liquified natural gas) reduces pressure through reducing valve 5, enter gas electricity unit 8, unit carries advances air assembly, can mix natural gas become " gas " combustion power generation, supply with gas and pump pump 1, can also supply with main fan and wait other equipment, make it operate as normal.
