Description of drawings
Fig. 1 is the structural representation of the multi-functional Nitrogen plant of the present invention.
Embodiment
To combine Figure of description below, the present invention will be further described.
As shown in Figure 1; A kind of multi-functional Nitrogen plant; Comprise air compressor machine 1, air cooler 8, strainer 10, Nitrogen plant 3 and two gas-holder 5; Also comprise blast dryer 2 and vacuum generator 4, said air compressor machine 1, air cooler 8, strainer 10, blast dryer 2, Nitrogen plant 3, gas-holder 5 are connected successively; Said vacuum generator is connected with gas-holder 5 with strainer 10 respectively; Be connected with an electronics hydathode SV1 on the air cooler 8; An air accumulator 9 also is installed between air cooler 8 and the strainer 10; Two gas-holder 5 are connected with the nitrogen pot 7 of Nitrogen plant 3 through first-hand movable valve SV4 and second-hand's movable valve SV8 respectively, and one of them gas-holder 5 also is connected with the nitrogen pot 7 of said Nitrogen plant 3 through a nitrogen SV SV7 by vacuum generator 4 control break-makes; Be connected with a nitrogen gas purity analyser 11 on the nitrogen pot 7 of Nitrogen plant 3.
The pressurized air of the 0.65-0.85MPa that air compressor machine 1 comes out cools off through air cooler 8, and removes operative liquid water, and SV1 carries out draining through the electronics hydathode, on electronics hydathode SV1, can set the pitch time of draining; With the air admission air accumulator 9 of removing liquid water; Make steady air current; Air in the air accumulator 9 is removed a small amount of steam of residue in the gas at entering blast dryer 2 after removing the particle in the gas through strainer then, and the pressurized air that produces like this gets into Nitrogen plant.
After pressurized air gets into Nitrogen plant 3; Get into adsorption tower 6 from the bottom of the adsorption tower 6 of Nitrogen plant 3, and the whole tower body of flowing through from lower to upper, owing to filled carbonaceous molecular sieve in the adsorption tower 6; Gas through the time because molecular diameter is different; Oxygen molecule is adsorbed on the carbonaceous molecular sieve surface more than nitrogen molecule, and the most of the nitrogen molecule is in unbound state, is flowed out by adsorption tower 6 upper ends.After after a while, carbonaceous molecular sieve is saturated by adsorbed oxygen molecule, need regenerate, and the oxygen molecule of great majority absorption is drained when step-down.For reaching continuous air feed, two duraluminum adsorption towers 6 are installed, in the Nitrogen plant when one of them is in the work adsorbed state; Another tower is a reproduced state; Prepare for absorption next time, adopt many valves group to automatically switch, whole process is controlled by programmable logic controller; On touch-screen, show working process, realized automatic production.
Utilization is connected the nitrogen gas purity in the nitrogen gas purity analyser 11 online detection nitrogen pots 7 on the nitrogen pot 7 of Nitrogen plant 3; But when the purity of nitrogen is defective; Can report to the police through programmable logic controller, after nitrogen gas purity was qualified, SV SV3 was in opened condition; Have the condition of backward supplying gas, nitrogen gas purity analyser 11 sends signal and gives programmable logic controller simultaneously.Controlled by Programmable Controller SV SV4 opens, be input to nitrogen in the gas-holder 5 that is connected with SV SV4, when with gas-holder 5 that SV SV4 is connected in inflation pressure reach requirement after; Close SV SV4; SV SV5 between Controlled by Programmable Controller vacuum generator 4 and the strainer 10 opens, and vacuum generator 4 is started working, when with gas-holder 5 that SV SV4 is connected in vacuum tightness when reaching requirement; Close SV SV5; The vacuum transmitter quits work, and simultaneously SV SV4 opens automatically, nitrogen continue to gas-holder 5 that SV SV4 is connected in inflated with nitrogen; Action above repeating, the number of times that vacuumizes can be set on touch-screen and revise through programmable logic controller.
Under the qualified situation of nitrogen gas purity, also can fill nitrogen to gas-holder 5, and can fill nitrogen pressure through what relief valve JY3 and relief valve JY5 regulated 2 road nitrogen through touch-screen manual unlocking SV SV7 and SV SV8.
In sum, a kind of multi-functional Nitrogen plant volume provided by the invention is little, in light weight, and the purity of the nitrogen of production is high, dew point is low; And carry the device that gas-holder is vacuumized, can realize that manual and automatic dual mode fills nitrogen to the gas-holder that has vacuumized through touch-screen, level of automation is high.
More than show and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification sheets just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain by appending claims and equivalent circle thereof.
