Abstract
The utility model discloses a colliery is waterproof current surveying metering device in pit, its characterized in that: it includes: gas -water separation device (1) is through air duct (11) and gas drying device (2) and metering device (3) intercommunication. The utility model provides a colliery is waterproof current surveying metering device in pit, it is water insoluble to utilize mine gas, and characteristics such as the density ratio air is light, with gaseous with water separates through gas -water separation device and pass through the gas drying device in the measuring aperture, make in the gas of surveying moisture -bearing not, thereby carry out effective dry protection to measuring metering device, and furthermore high accuracy of the measurement result is ensured, the reduction of very big degree damage and the possibility of measuring result distortion because of water leads to the instrument, make measuring result more accurate, effectively, thereby the better coal mine safe production that guides.
Description
Technical field
the utility model relates to a kind of underground coal mine waterproof flow measurement measuring apparatus, belongs to Coal Mining Technology field.
Background technology
Coal mine underground gas comparison of ingredients is complicated, and gaseous species is various, and it is exactly gas that down-hole exists the most general hazardous gas, and broad sense gas refers to the general name of down-hole harmful gas.In order to study coal-bed gas releasing degree and drawing-off gas degree, often need to measure drilling gas flow.Drilling gas flow determining method is a lot, is totally divided into and directly measures and indirect determination two kinds of modes.It is comparatively large to there is error in indirect determination flow measurement, and the shortcomings such as degree of accuracy is low, need to utilize direct measuring method to carry out drilling gas flow measurement sometimes.When such as calculating Permeability Coefficent in Coal Seam, directly measure with regard to needs time slightly high to drilling gas flow precise requirements.When directly measuring due to relevant restrictions such as measuring apparatus principle of work, measuring apparatus requires higher to waterproof degree, such as gas meter etc.But underground coal mine complicated condition, be difficult to ensure that not having swelling when measuring in boring goes out, once boring has swelling to go out, in hole, water burst directly will enter measuring apparatus, causes damage to measuring apparatus.Therefore find a kind of method that gas-water separation in hole is just seemed very important.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of underground coal mine waterproof flow measurement measuring apparatus, water is just had to cause instrument damage to solve in existing direct measuring to deposit, even affect the accuracy of measurement result, thus make measurement result distortion, well can not instruct safety in production.
Technology contents of the present utility model: a kind of underground coal mine waterproof flow measurement measuring apparatus, it comprises: gas and water separator is communicated with measuring apparatus with gas drier by wireway.
There is an ajutage to be communicated with external bottom gas and water separator, ajutage is installed on valve.
One opening is arranged at gas and water separator top, and opening has aperture plugging device shutoff, and draft tube one end is goed deep into bottom gas and water separator through opening aperture plugging device, and one end is connected with orifice; Short tube of giving vent to anger gos deep in gas-water separation gas through port closing device, and at gas and water separator topmost.
measuring apparatus has automatic gauge and Presentation Function, and has a metering device inlet end and an outlet side.
Short tube one end of giving vent to anger is connected with gas drier, and wireway one end is connected with drying cartridge, and one end is connected with metering device inlet end.
The beneficial effects of the utility model: the utility model designs a kind of underground coal mine waterproof flow measurement measuring apparatus, utilize mine gas water insoluble, and the features such as density lta, gas in measured hole is undertaken being separated and passing through gas drier by gas and water separator with water, make moisture-free in surveyed gas, thus efficient drying protection is carried out to measuring device, ensure that the accuracy of measurement result, high degree reduce because of water cause instrument damage and measurement result distortion may, make measurement result more accurate, effectively, thus better instruct Safety of Coal Mine Production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of underground coal mine waterproof flow measurement measuring apparatus, it comprises: gas and water separator 1 is communicated with measuring apparatus 3 with gas drier 2 by wireway 11.
There is an ajutage 4 to be communicated with external bottom gas and water separator 1, ajutage 4 is installed on valve 5.
One opening is arranged at gas and water separator 1 top, and opening has aperture plugging device 9 shutoff, and draft tube 7 one end is goed deep into bottom gas and water separator 1 through opening aperture plugging device 9, and one end is connected with orifice; Short tube 8 of giving vent to anger gos deep in gas-water separation gas 1 through port closing device 9, and at gas and water separator 1 topmost.
Measuring apparatus 3 has automatic gauge and Presentation Function, and has metering device inlet 6 end and an outlet side 12.
Short tube 8 one end of giving vent to anger is connected with gas drier 2, and wireway 11 one end is connected with drying cartridge 2, and one end is connected with metering device inlet end 6.
Concrete testing procedure:
Step one: before flow measurement, adds drying agent by gas drier 2, and all devices is installed device as shown in the figure and carry out tissue-welding.Draft tube 7 one end is connected with needs orifice by connection to be assembled later;
Step 2: block measuring apparatus outlet side 12 with hand, utilizes the portable watt of impermeability examining measuring device;
Step 3: utilize gas need not water-soluble and features such as density lta, in hole water after gas and water separator 1 because Action of Gravity Field is collected in bottom gas and water separator 1 automatically, when device internal water accumulation 10 increases, opening valve 5 allows water automatically flow out in ajutage 4, thus realizes gas-water separation.After above step one to be done and step 2, start timing, metric results directly reads from measuring apparatus 3.
Claims (3)
