Density will increase, and total hydrocarbon can generate a degree of damage to human body.
In the past, the total hydrocarbon content in diver's breathing gas as defined in national regulation was no more than 0.05mg/
m3, according to These parameters are difficult to realize at present for the gas supply cleaning equipment of submersible decompression chamber configuration, especially equipment operation is several
Realize that this index can be more difficult after time.According to measurement, the filtering element for air filter that a normal use period is 6000 hours,
Not pass through compressed air pretreatment system processing in the state of, when using 1000 it is small when after, the oil vapour of compressed air contains
Amount can reach every cubic metre of 0.1mg or more.Total hydrocarbon in compressed air can produce human cell membrane strong
Therefore toxicity damage realizes that oil-free gas supply has extremely important meaning to the health of diver.

Compared with prior art, the beneficial effects of the present invention are: by configuring water cooling for the air supply system of submersible decompression chamber
But, water-oil separating, preposition air reservoir, high efficiency particle air filter, cooling driers, thick air filter, smart air filter, high-precision
The equipment relevant to air cleaning of air filter, postposition air reservoir and active carbon adsorber etc. ten, realizes removing with this
The purpose of the liquid mixtures such as aerial oil, water is compressed, ensures that submersible decompression chamber obtains oil-free gas supply effect with this.
Detailed description of the invention
Fig. 1 is compressed air purifying flow diagram of the invention；
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.The present invention provides a kind of technical solution: as shown in Figure 1, a kind of submersible decompression chamber
Gas is comprised the steps of without oil purification processes:
The pretreatment of Step.1 compressed air；Start air compressor machine, the compressed air of output is after water cooler by gas
Temperature is reduced to 35 DEG C hereinafter, then by oil water separator, separates to the mixture in compressed air, in compressed air
Mixtures of impurities by entering preposition air reservoir after initial gross separation, precipitate with separate after enter high-efficiency degreasing device；Compression is empty
The degree of air cooling, compressed air temperature is lower, and the degree of water-oil separating will be better, conversely, will be poorer；In compressed air
Total hydrocarbon and compressed air in moisture content and dust granules mix to form liquid mixture, in compressed air
Temperature reduce, the easier precipitation and separation of these liquid mixtures.
PSA oxygenerator requires freeze drier air outlet temperature to be reduced to 2-3 DEG C, realizes that this temperature index need to will freeze
The air inlet temperature of drying machine can control at 45 DEG C or less.The air inlet temperature of freeze drier such as exceeds 45 DEG C, freeze-drying
The air outlet temperature of machine will increase therewith.Under standard state, freeze drier air inlet temperature is higher, the temperature of gas outlet
It will be higher.Minimum 80 DEG C of air compressor machine outlet temperature, the air inlet temperature of lyophilizer requires control at 45 DEG C hereinafter, temperature
If not can be carried out effective cooling processing for 80 DEG C of compressed airs, the liquid mixture in compressed air has been impossible to
Clear all, this is the normality phenomenon of current submersible decompression chamber gas supply purification system.Compressed air is being entered cooling driers by the present invention
It is pre-processed before, reduces compressed air temperature within 35 DEG C, and the mixtures such as oil, water in compressed air are reduced
To the level of 20-30%, in this way, laying the foundation for freeze drier and subsequent air filter, total hydrocarbon control can be made
Make the level for being no more than 1mg at every cubic metre.
The filtering of Stpe.2 multi-staged air；Enter cooling driers by the pretreated compressed air of compressed air system to carry out
After so that compressed air temperature is reduced to 2-3 DEG C, it is empty to enter back into thick air filter, smart air filter and superfinishing for low-temperature treatment
Air filter carries out gas deep purifying, then carries out precipitation and separation by postposition air reservoir.It is general main logical to intercept filtering
It crosses the prior art: directly intercepting, inertial collision, Blang's diffusion mechanism is good to tiny particles content collecting effect but windage is big, is
Acquisition high purification efficiency, filter core need fine and close simultaneously to regularly replace.Compressed air passes through air filter for liquid water, liquid
Oil droplet is separated, and filters off the dust in air and solid impurity.Particulate in air removal technology mainly have mechanical filter,
Absorption, electrostatic precipitation, anion and plasma method and the filtering of electrostatic electret etc..Mechanical Adsorption is the high surface area using material
And porous structure captures particulate pollutant, it is easy to it blocks, it is more significant for gas pollutant removal effect；Gas flow rate is got over
Fastly, the precipitated form of compressed air liquid mixture is poorer, otherwise better.Twice compression is arranged in the present invention in air supply system
Air cushion tank, with this ensure compressed air on stream can by the compressed air surge tank residence time as much as possible,
The effect for reducing flow velocity is played with this.High-efficiency degreasing device in the present invention is the filter material based on superfine fibre, has oil removing, removes
Dirt ability and certain dehumidification drying capacity；Air coarse filter can remove≤1 μm of dirt particle diameter；Under standard state, it can make
Level of the compressed air oil content processing to≤0.25ppm；Air fine filter can make dust-laden particle diameter≤0.1 μm；Oil content
≤0.001ppm；Air ultraprecise filter can make dust-laden particle diameter≤0.1 μm；Oil content≤0.0001ppm.
Stpe.3 adsorption cleaning；Active carbon adsorber, purification need to be entered through postposition air reservoir treated compressed air
Compressed air afterwards can enter adsorption tower and implement oxygen separation for zeolite molecular sieve；
Stpe.4PSA oxygen；
The filtering material of high speed oil expeller in the Stpe.2 uses superfine fibre.
The volume of preposition air reservoir and postposition air reservoir in the Stpe.1 and Stpe.2 should be equal to PSA oxygenerator
Single-machine capacity is divided by 5 or 6.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
