Background technology
In existing medical center oxygen generation system, what air pretreatment part adopted is all that simple cooling driers adds common filter to carry out and processes, its treatment effect: air dew point high (water content is large), oleaginousness is large, dust removing effects is not good etc., causes the concentration of oxygen main frame more and more to decline, and flow is also more and more not enough, and causing oxygen main frame again and again to break down problem, causing a lot of inconvenience for using.
Summary of the invention
The various drawbacks of the air pretreatment part of the technical problem to be solved in the present invention before being to provide a kind of avoiding in existing medical center oxygen generation system, and make the quality after purifying air exceed the medical center oxygen air-purification system of national sector standard.
For solving the problem, the present invention adopts following technical scheme:
A kind of medical center oxygen air-purification system, comprise efficient pre-cooler, vaporizer, compressor, condenser, expansion valve, strainer, drying tower one and drying tower two, described efficient pre-cooler is provided with dry air outlet and damp-heat air import, described efficient pre-cooler is connected with vaporizer, described vaporizer is connected with compressor cycle, described condenser and expansion valve are equipped on the pipeline be connected between vaporizer with compressor respectively, described condenser is connected with expansion valve, described efficient pre-cooler also accesses on drying tower one and drying tower two, described strainer is connected with vaporizer, described strainer access is below drying tower one and drying tower two, described strainer is also connected with automatic drain valve.
Further, described strainer is also equipped with on-line detector, dew point hygrometer and particle collector, ensures Air quality.
Further, described strainer is activated charcoal filter, the trace oil mist of the remnants in special removing pressurized air.
Another technical problem that the present invention will solve is to provide a kind of working method of medical center oxygen air-purification system.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: comprise the following steps:
1) first by damp-heat air import, air is taken in, and isolate most of water smoke, dust, oil droplet in gas by efficient pre-cooler;
2) sending into drying tower one and drying tower two after the gas after being separated being carried out a series of process via vaporizer, compressor, condenser and expansion valve carries out except water treatment;
3) when gas dew point≤-40 DEG C at ambient pressure, again cycle through strainer and carry out dedusting, oil removal treatment.
The invention has the beneficial effects as follows: this medical center oxygen air-purification system not use only the air compressor unit of efficient energy-saving, there is linkage function, ensure that working continuously of system, but also adopt multistage high-accuracy, ultra-high efficiency filtration, purification system, purified drying obtains without oily tasteless clean gas source, guarantee to meet GB/T23331-2012 and ISO50001 energy management system standard, ISO8573-1 and ISO9001 international standard, and adopt electronics blowdown technology, blowing period can be set, water of condensation and greasy dirt in energy automatic discharge system, oil-containing on-line detector simultaneously, dew point hygrometer and particle collector can carry out complete monitoring, ensure Air quality.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of medical center oxygen of the present invention air-purification system.
Embodiment
Consult shown in Fig. 1, a kind of medical center oxygen air-purification system, comprise efficient pre-cooler 4, vaporizer 3, compressor 5, condenser 7, expansion valve 6, strainer 11, drying tower 1 and drying tower 2 10, described efficient pre-cooler 4 is provided with dry air outlet 1 and damp-heat air import 2, described efficient pre-cooler 4 is connected with vaporizer 3, described vaporizer 3 circulates with compressor 5 and is connected, described condenser 7 is equipped on expansion valve 6 pipeline be connected between vaporizer 3 with compressor 5 respectively, described condenser 7 is connected with expansion valve 6, described efficient pre-cooler 4 also accesses on drying tower 1 and drying tower 2 10, described strainer 11 is connected with vaporizer 3, described strainer 11 accesses below drying tower 1 and drying tower 2 10, described strainer 11 is also connected with automatic drain valve 12.
Described strainer 11 is also equipped with oil-containing on-line detector (not shown), dew point hygrometer (not shown) and particle collector (not shown), can complete monitoring be carried out.
Described strainer 11 is activated charcoal filter, filters mist of oil.
A working method for medical center oxygen air-purification system, comprises the following steps:
1) first by damp-heat air import 2, air is taken in, and isolate most of water smoke, dust, oil droplet in gas by efficient pre-cooler 4;
2) sending into drying tower 1 and drying tower 2 10 after the gas after being separated being carried out a series of process via vaporizer 3, compressor 5, condenser 7 and expansion valve 6 carries out except water treatment;
3) when gas dew point≤-40 DEG C at ambient pressure, again cycle through strainer 11 and carry out dedusting, oil removal treatment.
Principle of work:
Gas after compressor 5 compresses is first after condenser 7 is except water for cooling, and efficient pre-cooler 4 isolates most of water smoke, dust, oil droplet in gas; Sending into drying tower 1 and drying tower 2 10 again carries out except water treatment, make gas dew point at ambient pressure reach≤-40 DEG C, alleviate the load of postorder purification assembly, the more important thing is, also can improve adsorption efficiency; Carrying out dedusting, oil removal treatment, deep purifying through the strainer 11 of 0.01 μm again, requiring when keeping certain pressure reduction according to system condition, the even more filter assemblies of level Four also can be set to reach air quality indexes; The activated charcoal filter set up aims at trace oil mist design configurations remaining in removing pressurized air, through oil-removing purifier to after pressurized air deep purifying, oleaginousness is down to the pressurized air that 0.003mg/m3 touches the mark and is entered air accumulator again, design the work-ing life that rigorous clean air package ensure that molecular sieve, meanwhile, the part uncontaminated air after the process of this assembly is used for instrument air.
