Description
Technical field
The utility model relates to a kind of gas separation equipment, especially relates to a kind of transformation adsorbed gas separation equipment.
Background technology
The transformation absorption principle is to utilize adsorbent that adsorbate has been depressed different adsorption capacity, adsorption rate and absorption affinity at different branches; And the characteristic that under certain pressure, each component of separated admixture of gas is had the absorption selected; The impurity composition in the unstripped gas is removed in pressurization absorption, decompression these impurity of desorption and make adsorbent obtain regeneration.
Variable-pressure adsorption equipment mainly is made up of adsorption tower and the control system that A, two of B are equipped with molecular sieve.When compressed air passed through the A tower from bottom to up, oxygen, carbon dioxide and moisture were adsorbed by carbon molecular sieve, and nitrogen is then passed through and flows out from cat head.When molecular sieve adsorption is saturated in the A tower, just switch to the B tower and carry out above-mentioned adsorption process and simultaneously A tower molecular sieve being regenerated.So-called regeneration drains into atmosphere and makes pressure be reduced to normal pressure rapidly thereby is about in the adsorption tower gas.
But in the prior art, adsorption process and regenerative process need be provided with corresponding pipeline respectively, and its structure is comparatively complicated, and the part pipeline but obtains vacantly for a long time, and the air-tightness of system also more is difficult to guarantee.
Summary of the invention
The utility model mainly be solve that the existing in prior technology pipeline is many, complex structure, pipeline can not rationally be utilized, air-tightness is difficult to guarantee technical problem; Provide a kind of simple in structure, easy to operate; Pipeline is fully used, the control system of the transformation adsorbed gas separation equipment that air-tightness guarantees easily.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of control system of transformation adsorbed gas separation equipment; Comprise A tower, B tower and corresponding pipeline; It is characterized in that described pipeline is divided into air inlet pipeline and outlet pipe; Described air inlet pipeline is provided with a two-position-five-way solenoid valve; Each valve position one side of this two-position-five-way solenoid valve links to each other with A tower blast pipe, B tower blast pipe and total inlet pipe respectively, and opposite side links to each other with B tower air inlet pipe with A tower air inlet pipe respectively.When the air inlet of A tower, during the emptying of B tower, compressed air enters into filtration, the screening of A tower inlet air through magnetic valve and A tower air inlet pipe, and the residual gas of B tower is oppositely through B tower air inlet pipe and magnetic valve discharge; When the air inlet of B tower, during the emptying of A tower, magnetic valve switches valve position, and compressed air enters into filtration, the screening of A tower inlet air through magnetic valve and B tower air inlet pipe, and the residual gas of A tower is oppositely through A tower air inlet pipe and magnetic valve discharge.Thereby realized simple in structurely, easy to operate, pipeline is fully used, the characteristic that air-tightness guarantees easily.
As preferably, be respectively equipped with quick release valve on described A tower air inlet pipe and the B tower air inlet pipe.
As preferably, described outlet pipe is respectively equipped with check valve by A tower escape pipe and B tower escape pipe on A tower escape pipe and the B tower escape pipe, and the logical scavenging pipeline of the inlet end of this check valve links to each other, and this scavenging pipeline is provided with a stop valve.When the pressure of regenerator is identical with ambient pressure, need purge its air inlet through finished product gas and could realize it is carried out holomorphosis, open stop valve at this moment, by finished product gas regenerator is purged.
The beneficial effect that brings of the utility model is; Solved that the existing in prior technology pipeline is many, complex structure, pipeline can not rationally be utilized, air-tightness is difficult to guarantee technical problem; Realized a kind of simple in structure, easy to operate; Pipeline is fully used, the control system of the transformation adsorbed gas separation equipment that air-tightness guarantees easily.
