Air separation plant of the present invention comprises air compressor machine, cooler and the filter that pipeline connects, filter connects pressure-swing absorption apparatus by valve control device, the entrance point of each adsorption tower all is in series with drying tower and constitutes drying-absorption associated units, and the port of export of each adsorption tower is communicated with formation finished product gas blowback regeneration water conservancy diversion path by valve.
The present invention uses the bed series connection of the bed of adsorption tower and drying tower, can utilize the emptying end gas of adsorption tower and the regeneration gas drying tower of regenerating, and economizes on tolerance, reduces energy consumption, and flow process is reasonable, and operating cost reduces.And, reduced the valve control system of independent use Heatless Regeneration Compressed Air Drying Equipment in the air separation plant, saved the hardware device cost, improved the control effect.
Valve control device in the air separation plant of the present invention can adopt the multiposition valve more than five mouthfuls, general two five-way valves or the three position five-way valve of adopting, can substitute the control action that realizes two intake valves and two air bleeding valves with a valve like this, reduce equipment cost more.Air compressor machine can also adopt oilless air compressor, need not to carry out the oil removing configuration like this, improves the empty quality of producing of dividing.
Further specify the present invention below in conjunction with drawings and Examples.
Description of drawings:
Fig. 1 is the air separation plant structural representation of embodiment 1;
Fig. 2 is the air separation plant structural representation of embodiment 2.
Embodiment 1: as shown in Figure 1, air compressor machine 1, cooler 2 and filter 3 pipelines are connected, and filter 3 connects pressure-swing absorption apparatus by multiposition valve 6.The entrance point of each adsorption tower 5 all is in series with drying tower 4 and constitutes drying-absorption associated units, and the port of export of each adsorption tower 5 is communicated with formation finished product gas blowback regeneration water conservancy diversion path by valve 7.Present embodiment adopts the double-tower type pressure-swing absorption apparatus, and adsorption tower 5A or 5B also can connect to form equivalent device by a plurality of little adsorption towers respectively. Drying tower 4A or 4B can be made up of a plurality of little drying towers respectively too, and effect is equal to.The multiposition valve 6 of present embodiment adopts three position five-way valve, and two ends are by magnetic valve SV1 and SV2 control.
During the equipment operation, the compressed air of oilless air compressor 1 output is after subcooler 2 coolings, through filter 3 filtration, purifications, with aqueous water and solid impurity filtering.Magnetic valve SV1 opens, compressed air enters the series connection associated units of drying tower 4B and adsorption tower 5B and carries out the operation of sky branch, present embodiment is to produce oxygen empty the branch, finished product oxygen flows out by check valve ZV2, part of oxygen purges regeneration by the beds connected in series that valve 7 blowbacks flow into drying tower 4A and adsorption tower 5A simultaneously, and regeneration off gases is by silencer 8 emptying.After the beds connected in series absorption of drying tower 4B and adsorption tower 5B is finished, magnetic valve SV1, SV2 close or magnetic valve SV1, SV2 open simultaneously, make multiposition valve 6 be in full envelope state, simultaneously magnetic valve SV4 opens, and the oxygen rich gas of the series connection associated units of drying tower 4B and adsorption tower 5B all is pressed onto in the series connection associated units of drying tower 4A and adsorption tower 5A to recycle.Magnetic valve SV4 closes afterwards, magnetic valve SV2 opens, compressed air enters the series connection associated units of drying tower 4A and adsorption tower 5A and produces the oxygen operation, oxygen flows out by check valve ZV1, part of oxygen purges regeneration by the beds connected in series that valve 7 flows into drying tower 4B and adsorption tower 5B simultaneously, and waste gas is by silencer 8 emptying.After the beds connected in series absorption of drying tower 4A and adsorption tower 5A is finished, magnetic valve SV1, SV2 close or magnetic valve SV1, SV2 open simultaneously, make multiposition valve 6 be in full envelope state, magnetic valve SV3 opens simultaneously, the oxygen rich gas of the series connection associated units of drying tower 4A and adsorption tower 5A all is pressed onto in the series connection associated units of drying tower 4B and adsorption tower 5B and recycles, magnetic valve SV3 closes afterwards, and magnetic valve SV1 opens, periodic cycle operation like this.
