Description
Technical field
The present invention relates to water treatment facilities, relate in particular to, change the mixed running gear that series, parallel switches that adopts according to water quality and quantity producing in the desalted water processing system with mixed ion exchanger (be designated hereinafter simply as and mix bed).
Background technology
In the chemical enterprise, it is reverse osmosis membrane system+mixed-bed system that desalted water commonly used is at present produced flow process.Produce the used water source of desalted water and comprise surface water, underground water, desalinization water or waste water treating and reutilizing water etc.The former water of different quality is after reverse osmosis unit is handled, and contained ionic species and concentration have nothing in common with each other in the water of the mixed bed of entering, and the mixed bed processing of single-stage that only needs that has just can reach water standard, also has the series operation of the mixed bed of the secondary of needs just can reach water standard.Existing single-stage is mixed the bed handling process and is seen Fig. 1, and secondary mixes the bed handling process and sees Fig. 2.
A lot of chemical plant need because of the restriction and the water saving at water source, adopt multiple water source to unite the mode of producing desalted water usually, perhaps use fresh water as the water source at the driving initial stage, use the situation at conversion water sources such as recycle-water in the runtime.Domestic technique is considered less to the process optimization of this situation; Mode commonly used at present is to be designed to secondary by worst water quality to mix the bed operating form; Mainly there is following problem in such technical scheme: (1) is when changing the water source; Equipment component is in stops using or the overload operation state, and equipment investment is big, and operating cost is higher.(2) first and second grade mixed ion exchanger condition of work is different, and first order mixed-bed resin live load is big, and the regeneration period is short, and second level mixed-bed resin live load is little, and the regeneration period is long; Two-stage is mixed bed regeneration simultaneously when (3) regenerating, and the regenerative agent consumption is big.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of the best that can reach to use water condition, guarantee that all resin regeneration cycles are balanced, increase resin life, mix the improved mixed ion exchanger connection in series-parallel running gear that bed is regenerated and can be carried out respectively.
Improved mixed ion exchanger connection in series-parallel running gear of the present invention; It comprises that one-level is mixed bed and secondary mixes bed and water inlet manifold; One-level is housed on it mixes that a end that the one-level of bed water intaking valve mixes the bed inlet pipeline is connected with water inlet manifold and its other end is connected with the water inlet of mixed of one-level; Be equipped with successively on it that a end that secondary mixes first inlet pipeline of a bed water intaking valve, the 6th coupling cock and the 5th coupling cock is connected with water inlet manifold and its other end be positioned at one-level and mix the mixed inlet pipeline of an one-level of the bed water intaking valve port of export and be connected; One-level is housed on it mixes that a port of export that a end that the one-level of bed outlet valve mixes the bed outlet pipeline and one-level mix bed is connected and its other end is connected with outfall sewer; One end of second inlet pipeline is connected with a water inlet that mixes at secondary that first inlet pipeline between bed water intaking valve and the 6th coupling cock is connected and its other end and secondary mix bed; Be equipped with on it that a delivery port that a end that secondary that secondary mixes the bed outlet valve mixes the bed outlet pipe and secondary mix bed is connected and its other end is connected with outfall sewer; Be equipped with on it the 7th coupling cock and the 8th coupling cock outlet pipeline an end be positioned at that one-level mixes that the one-level of the water inlet end of bed outlet valve mixes that the bed outlet pipeline is connected and its other end mixes an outlet pipeline and is connected with being positioned at secondary that secondary mixes the water inlet end of bed outlet valve, an end of connecting line be connected at first inlet pipeline between the 5th coupling cock and the 6th coupling cock and its other end links to each other with outlet pipeline between the 7th coupling cock and the 8th coupling cock.
Beneficial effect of the present invention and advantage are: (1) according to the source quality situation, the convenient adjustment method of operation reaches the best and uses water condition.(2) the system automation degree is high, reduces operation easier.(3) it is interchangeable that series connection mixes the bed secondary, guarantees that all resin regeneration cycles are balanced, increases resin life.(4) mix bed regeneration and carry out respectively, save acid-alkali regeneration agent consumption, reduce and pollute.
