Description
Technical field
The present invention relates to well mine salt brine treatment field, relate to a kind of well mine salt bittern pretreatment process especially.
Background technology
Well mine salt refers to that the salt and the salt of recovery of subterranean rock salt through being processed into that underground natural bittern makes is drawn in drilling well.The production process of well mine salt divides mining and salt manufacturing two parts.Underground natural bittern bailing method, gas lift method or Submerged bittern pump draw; Rock salt is according to geology of mineral deposit, occurrence condition and grade height, and point roadway exploits (drought is adopted) and solution mining.
In rock salt drilling solution mining process, often there are the gas together outputs such as methane, hydrogen sulfide, methane total hydrocarbon; Can not process for processing be directly used in, need to carry out pre-treatment to bittern, isolate associated gas contained in bittern.Also need to carry out reprocessing to the associated gas after being separated, often in well mine salt bittern, the content of associated gas is unstable and tolerance is few, can not produce the value of recycling simultaneously.If directly discharge not only can polluted air, when reaching finite concentration, also harm can be brought to the healthy of neighbouring resident.Current way is discharged after directly burning.It is inadequate to there is separation degree in existing isolation technique, tolerance instability cause burning time burn insufficient, the exhaust emission of combustionmaterial is larger, noise is large, easily stops working, and needs artificial relight, improve the danger coefficient of operative, in addition, adopt open type collection halogen to still have associated gas to overflow, pollute the shortcomings such as surrounding enviroment.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical problem to be solved by this invention is: provide a kind of well mine salt bittern separation degree high, the associated gas sufficient combustion be separated, the exhaust emission of combustionmaterial is less, noise is little, not easily stops working, without the need to artificial relight, reduce the danger coefficient of operative, adopt closed collection halogen to pollute little pretreatment process.
In order to solve the problems of the technologies described above, present invention employs following technical scheme:
A kind of well mine salt bittern pretreatment process, in the method, first by after the water inlet of bittern water inlet manifold, water inlet is separated into bittern and associated gas two portions by a moisture separator again, then brine transportation is carried out salt manufacturing to salt manufacturing workshop, associated gas is transported to waste gas burner burning, it is characterized in that, before associated gas is transported to waste gas burner, the moisture be mingled with is separated and be back to salt manufacturing workshop in associated gas, to ensure waste gas burner combustion efficacy and to improve bittern utilization ratio.
In the method, specifically comprise the following steps:
A, first obtain the well mine salt bittern pretreatment system of following structure, this system comprises bittern water inlet manifold, with the moisture separator that bittern water inlet manifold is connected, moisture separator water side is connected to salt manufacturing workshop by outlet conduit, outlet conduit is provided with halogen transmitting pump, moisture separator outlet side is connected to waste gas burner by outlet pipe, described outlet pipe is provided with air water separator, the inlet mouth of described air water separator is connected with the outlet side of described moisture separator, and the air outlet of described air water separator is connected with described waste gas burner; Water outlet bottom described air water separator by pipeline communication to salt manufacturing workshop.
