Based on above-mentioned problem, the present invention proposes the acquisition method of a kind of salt lake underground deep layer bittern.
Summary of the invention
The object of the invention is to solve that the comparatively large and dark down-hole pump & of existing brine collection pump power used takes out that pump & washes that pump is more difficult, be easy to problems such as burning out in pump operation process, propose the acquisition method of a kind of salt lake underground deep layer bittern.
The present invention proposes the acquisition method of a kind of salt lake underground deep layer bittern, comprises 1) sleeve pipe made by diameter 108mm ~ 159mm steel pipe is inserted into the underground deep layer bittern of salt lake from ground; 2) be that the high-voltage tube that 30mm ~ 60mm high-intensity flexible pipe is made is inserted into the underground deep layer bittern of described salt lake from ground by diameter; 3) producing 1.5MP ~ 2.5MP pressure by air compressor machine is pressed in described high-voltage tube by air, and described bittern is delivered to ground along described sleeve pipe by pressure-air; 4) mixture of the described bittern and gas of delivering to ground enters in gas-liquid separator, isolates described gas and is discharged by stack, and isolated described bittern is that the mozzle that 200mm ~ 300mm steel pipe is made flows in halogen canal by diameter again, completes brine collection.
Further, described mozzle is with electromagnetic flowmeter.
Further, described high-voltage tube is with wireless baroceptor.
Preferably, described wireless baroceptor gathers the air pressure information in high-voltage tube, and by mobile communications network, described pressure information is passed to operating personnel.
Preferably, described pressure information comprises normally, pressure weakens, warn three kinds of states.
The acquisition method of a kind of salt lake provided by the invention underground deep layer bittern, adopts air compressor machine, air compressing is delivered to shaft bottom through high-voltage tube, bittern is depressed into ground along sleeve pipe by gases at high pressure again, be separated through gas, liquid, bittern flow to halogen canal, completes and adopts halogen operation, device therefor power is little, and it is not integral device build ground in, fragile, be easy to safeguard, good stability, high financial profit.
Other features and advantages of the present invention will be set forth in the following description, and, partly become apparent from manual, or understand by implementing the present invention.Object of the present invention and other advantages realize by structure specifically noted in write manual, claims and accompanying drawing and obtain.
