| Average particle size particle size (mm) | 3.9-4.2 |
| Bulk density (kg/m^3) | ≧680 |
| Crushing strength (N) | ≧75 |
| Equilibrium water adsorption capacity (wt, %) | ≤ 21% |
| Residual water content (wt, %) | ≤ 1.5% |
In addition PSA (pressure-variable adsorption) gas absorption isolation technics is preferably used in the molecular sieve adsorber, it can be by this point
The impurity and oil discharge that son sieve absorber absorbs, and use the molecular sieve of pressure swing type absorption principle and the above-mentioned type can be with
So that not -40 DEG C or less of the pressure leak source of air-treatment host provided by the invention.
The working principle that air compresses host is as follows:
By taking the work of the first adsorption tower 93, the absorption of the second adsorption tower 94, working time 3min-10min as an example, firstly, first
Intake valve 95 and second row air valve 98 are opened, and the second intake valve 96 and first row air valve 98 are closed, from air inlet 9110 enter into
The first intake valve of gas approach 95 of feed channel 9120 enters the lower part of the first adsorption tower 93, passes through the first intake valve from bottom to top
It is discharged after 95 processing from the outlet of the first adsorption tower 94, and the first check valve of approach 911 is discharged from gas outlet 9210, the first absorption
Molecular sieve work in tower 93, absorbs the moisture or oil content impurity in air.When work 200s-300s after (time can set)
Two exhaust valves 98 are closed, and shuttle valve 910 is opened, and the gas approach shuttle valve 910 in the first adsorption tower 93 enters the second adsorption tower 94, are made
Air pressure in second adsorption tower 94 rise to it is consistent or almost the same with the first adsorption tower 93, arrive 300s to 400s when, second into
Air valve 96 and first row air valve 97 are opened simultaneously, and the first intake valve 95 is closed, the gas approach throttling ball in the second adsorption tower 94
Valve 99 enters the first adsorption tower 93, parses moisture content or the oil content impurity etc. in the first adsorption tower 93, moisture content or oil content from top to bottom
Impurity etc. can be discharged from first row air valve 97, in short, the first adsorption tower 93 and the second adsorption tower 94 can be adsorbed alternately
And parsing, preferably to adsorb to the moisture content in compressed air, guarantees so that remaining drying in molecular sieve adsorber
The compressed air that gas outlet comes out reaches first quality standard.
It is detailed introduction of the invention above, specific case used herein is to the principle of the present invention and embodiment party
Formula is expounded, method and core concept of the invention that the above embodiments are only used to help understand.It should refer to
It out, for those skilled in the art, without departing from the principle of the present invention, can also be to the present invention
Some improvement and modification can also be carried out, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
