Abstract
The present invention relates to a kind of non-loaded startup gas recovery system of deep-sea sealed compartment.The gas circuit drawn from waste gas pump discharge is divided into non-loaded startup auxiliary air passage and the main gas circuit of waste gas recovery.Magnetic valve is set on non-loaded startup auxiliary air passage, its exhaust outlet communication seals cabin internal gas.The magnetic valve is obtained after electric-opening so that the air pressure of waste gas pump steam inlet and exhaust outlet is consistent, i.e. the draught head of the inlet and outlet of waste gas pump mouthful is zero, so as to ensure that the gas circuit can realize the non-loaded startup of waste gas pump.After waste gas pump startup is finished, then it is switched in the main gas circuit of waste gas recovery, completes waste gas recovery.Magnetic valve and check valve are set in the main gas circuit of waste gas recovery, for carrying out the collection of waste gas and controlling the flow direction of gas.The present invention is easily installed in the suitable position of sealed compartment, quick start with closing can be realized according to instruction simultaneously, reach the effect of air pressure control in the reasonable scope in sealed compartment, and ensure that the general power of instrument and equipment in sealed compartment will not be because waste gas pump starting current overloads and exceeds restriction scope.
Description
Technical field
The invention belongs to marine survey technology field, and in particular to a kind of waste gas recovery dress being installed in the sealed compartment of deep-sea
Put, it can reach non-loaded startup waste gas pump during certain value by pressure in sealed compartment, gas sampling is stored into waste gas bottle
Get up, so that the gas pressure in sealed compartment is dropped under safety value.
Background technology
Deep-sea sealed compartment is that indispensable instrument platform is explored in ocean, is typically designed to pressure-resistant container to prevent sea
Water enters in cabin, it is ensured that scientific instruments equipment in the sealed compartment normal work under atmospheric pressure environment.Many scientific instruments equipment fortune
Gas is needed to use during row, and discharges waste gas, but when waste gas discharge is too many so that when gas pressure is excessive in sealed compartment, meeting
Cause the scientific instruments equipment of the ability normal work under atmospheric pressure environment can not normal work.Such as gas chromatograph, work under water
As when need to use high-purity nitrogen or helium to be detected as carrier gas to the gas obtained in being separated from seawater, and discharge
Large quantity of exhaust gas is in sealed compartment；When in sealed compartment waste gas accumulation to a certain extent, when the gas pressure is more than a certain numerical value,
The detector of gas-chromatography just can not normal work.And it is the gas discharged in high pressure sea water environment, cabin out of my cabin to seal（Waste gas）
It can not be directly discharged in surrounding seawater.Accordingly, it would be desirable to a kind of gas recovery system suitable for deep-sea sealed compartment is designed, when
Gas in sealed compartment（Waste gas）The gas sampling in cabin can be stored into waste gas bottle during hypertonia, to reduce gas in cabin
Body pressure so that pressure is remained in the pressure limit of scientific instruments equipment normal work in cabin.
Waste gas pump and waste gas bottle, can be joined directly together by the waste gas recovery in sealed compartment, and gas is extracted in cabin simultaneously by waste gas pump
Waste gas bottle is pressed into reclaim waste gas.Although this scheme is simple, as gas is constantly assembled in waste gas bottle, gas in waste gas bottle
Pressure constantly increases so that waste gas pump discharge pressure increase, the starting current of waste gas pump will increase therewith.Due to outlet pressure
Power（Load）Become big so that starting current is significantly larger than the several times of rated value, typically rated current, adds opening for waste gas pump
Dynamic difficulty.Starting current increase can also influence the normal work of other scientific instruments equipments in sealed compartment.Excessive starting current
The general power of sealed compartment clinical practice instrument and equipment can be caused to overload.When box of plugging under water monitors to be connected the total of branch road with sealed compartment
Power is beyond when limiting scope, and the power supply that will automatically cut off the branch road is exported so that all scientific instrument in sealed compartment are set
It is standby all to work.
The present invention can be achieved the non-loaded startup of waste gas pump, starting current be greatly lowered by setting up auxiliary air passage；By
In avoiding starting current from overloading, the normal work of other scientific instruments equipments in sealed compartment is also ensure that, not by the shadow of waste gas pump
Ring.
The content of the invention
It is reliable it is an object of the invention to provide a kind of principle, can be greatly lowered the deep-sea sealed compartment of starting current without
Load starts gas recovery system, realizes the waste gas recovery in sealed compartment into waste gas bottle to maintain the work(of stable gas pressure in cabin
Energy.
