The three-stage amine liquid recovery device sequentially comprises a primary filter, a secondary filter and a three-stage filter which are sequentially connected in series; the filter element of the primary filter adopts a wedged metal wire wound filter element, namely the filter element is formed by winding a metal wire, the longitudinal section of the filter element is wedged, and a filtering gap adopts a funneled structure; the secondary filter adopts a resin bed; the three-stage filter adopts a powder sintered filter element. The three-stage amine liquid recovery device provided by the invention has the advantages that the structure is reasonable, and amine passivation can be achieved basically; the foaming of the amine liquid is greatly relieved, and amine liquid loss can be reduced.
Description
Technical field
The present invention relates to a kind of tertiary amine liquid retracting device.
Background technology
In industries such as petrochemical industry medicine,, the trace impurity that amine aqueous solution is brought into due to pretreatment process, and the reasons such as degraded of amine itself, can constantly produce some anion in amine liquid, and be combined with amine and generate a kind of salt.If these salt are constantly accumulation in amine liquid, bring series of problems will to chemical plant installations below.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, the tertiary amine liquid retracting device that amine liquid recovery utilization rate is high.
Technical solution of the present invention is:
A liquid retracting device, is characterized in that: the grade one filter, secondary filter, the tertiary filter that comprise series connection successively; The filter core of described grade one filter adopts wedge wire winded filtering core, and filter core has wire to be entwined, and longitudinal section is wedge shape, and filtration gap is funnel-shaped structure; Described secondary filter is resin bed; Described tertiary filter is powder sintered filter core.
Grade one filter comprises two filters in parallel, one of them uses, one standby, two filters in parallel are connected with automatic back-washing device.
Secondary filter comprises the upper strata that the bottom that is comprised of cocoanut active charcoal carbon bed and resins exchange film form.
The present invention is rational in infrastructure, can substantially realize the passivation of amine; Greatly alleviate the foaming of amine liquid, reduce the race of amine liquid and damage.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is wedge wire winded filtering core structural representation.
Fig. 3 is wedge wire winded filtering core fundamental diagram.
The specific embodiment
A liquid retracting device, comprises grade one filter 1A, 1B, secondary filter 2, the tertiary filter 3 of connecting successively; The filter core of described grade one filter adopts wedge wire winded filtering core, be that filter core has wire to be entwined, and longitudinal section is wedge shape, filtration gap is funnel-shaped structure, its function is for removing the impurity in amine liquid, and accuracy rating is 51 ~ 30 microns, owing to filtering gap, is funnel type structure, solid particle can not rest on filter core inside, is convenient to backwash; Described secondary filter is resin bed; Described tertiary filter is powder sintered filter core, and filtering accuracy is high, up to 1 micron, reaches service life more than 10 years.
Grade one filter comprises two filter 1A, 1B in parallel, one of them uses, one standby, two filters in parallel are connected with automatic back-washing device.
Secondary filter comprises that the bottom being comprised of cocoanut active charcoal carbon bed (shears brokenly bubble to there is foam-like group in amine liquid, destroy to form the elastic gel layer of foam, solved and adopted fiber type filter part to exist surface to form the problem that air film causes vapour lock) and the upper strata of resins exchange film composition.
