Description
Technical field
The invention belongs to water treatment field, be specifically related to a kind of boiler water processing system.
Background technology
Existing boiler water processing technique mainly contains ion exchange method and reverse osmosis membrane is processed.
The first is mainly used in low pressure unit, the main flow process of boiler water system: former water → bis-medium filter → reverse osmosis unit → Na-ion exchanger → softening waters
The second is mainly used in mesohigh and above unit, the main flow process of boiler water system: former water → bis-medium filter → reverse osmosis unit → carbon dioxide cleaner → mixed ion exchanger → de-mineralized waters
By above two kinds of processing technological flow, can be found out, owing to being applied to the boiler of different pressures grade, two kinds of processing modes are different in advanced treatment, and the first process using Na-ion exchanger softens reverse osmosis water outlet, removes the residual harness in water; The second process using mixed ion exchanger carries out deep desalting to reverse osmosis water outlet.But identical point has all adopted reverse osmosis to carry out pre-desalting treatment.
It is to provide power by high-pressure pump that reverse osmosis method is processed, and utilizes the through performance Separation of Water intermediate ion of reverse osmosis membrane, present stage the first-stage reverse osmosis rate of recovery of conventional surface water be 75%, the auxiliary water ratio of reverse osmosis water processed is up to 25%.In the northern area of China, shortage of water resources, therefore, no matter be from reducing investment and running cost, or the consideration of environmental protection aspect, all should select a kind of technique of more saving water and energy.
Summary of the invention
The problem that the present invention mainly solves is to provide a kind of boiler water processing system, to solve existing boiler water processing system, adopts reverse-osmosis treated auxiliary water ratio high, and large problem consumes energy.
For realizing above object, the invention provides a kind of boiler water processing system, comprise two medium filters, dication interchanger, carbon dioxide cleaner, two chambers anion exchanger, two medium filter water-ins connect former water, two medium filter water outlets connect two chambers cation exchanger water-in, carbon dioxide cleaner water-in connects two chambers cation exchanger water outlet, and carbon dioxide cleaner water outlet connects two chambers anion exchanger water-in, and two chambers anion exchanger water outlet connects de-mineralized water.
Further, also comprise mixed ion exchanger, mixed ion exchanger water-in connects two chambers anion exchanger water outlet, and mixed ion exchanger water outlet connects de-mineralized water.
The technology of the present invention mature and reliable, auxiliary water ratio is generally 5%, and reverse osmosis system auxiliary water ratio reaches 25%, if boiler water processing system is exerted oneself, be 100t/h, reverse osmosis system is than ion exchange system many water consumptions 20t/h per hour, 10 yuan/ton of the service waters of take are example, many 200 yuan of water producing cost per hour, therefore with respect to reverse-osmosis treated, energy consumption is low, there is good economy, in water-deficient area, be worth of widely use especially.

Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.Below in conjunction with accompanying drawing, the present invention is described in detail.
embodiment 1:
Referring to Fig. 1 and Fig. 2, the invention provides a kind of boiler water processing system, comprise two medium filters, two chambers cation exchanger 1, carbon dioxide cleaner 2, two chambers anion exchanger 5, two medium filter water-ins connect former water, two medium filter water outlets connect two chambers cation exchanger 1 water-in, carbon dioxide cleaner 2 water-ins connect two chambers cation exchanger 1 water outlet, and carbon dioxide cleaner 2 water outlets connect two chambers anion exchanger 5 water-ins, and two chambers anion exchanger 5 water outlets connect de-mineralized water.
Preferably, also comprise mixed ion exchanger, mixed ion exchanger water-in connects two chambers anion exchanger 5 water outlets, and mixed ion exchanger water outlet connects de-mineralized water.
Boiler water processing system of the present invention, if for middle low-pressure boiler, directly carries out one-level desalination, after the anion exchanger of two chambers, does not need to add mixed ion exchanger again.If for high pressure and the above unit of high pressure, must carry out deep desalting, must add mixed ion exchanger after the anion exchanger of two chambers.
The present invention adopts two chambers cation bed, and two chambers anion bed replaces respectively single of negative and positive, and in lifted bed, double, weak type and strong type resin are equipped with respectively in upper and lower chamber, because the operating capacity of Weak Type Resin is large, therefore can improve the regeneration period, reduces labour intensity.The operation of considering operations staff is convenient, and negative and positive bed adopts unit system to connect, and a fortune one is standby, replaces existing reverse osmosis to produce one-level de-mineralized water.
Cation exchanger 1 water inlet in two chambers is the clear water after two medium filters filter, meet the water inlet requirement of ion-exchange unit, through two chambers cation exchanger 1, displace positively charged ion in water, cation exchanger 1 water outlet of two chambers enters carbon dioxide cleaner 2, remove the free carbon dioxide in water, enter two chambers anion exchanger 5, displace negatively charged ion in water, through one-level desalination, produce one-level de-mineralized water.Also intermediate water tank 3 can be set, make the water of carbon dioxide cleaner 2 outlets enter intermediate water tank 3, then promote and enter two chambers anion exchanger 5 through middle water pump 4.
One-level desalination effluent quality:
Hardness :～0 μ mol/l
Silicon-dioxide :≤100 μ g/l
Specific conductivity :≤5 μ s/cm(25 ℃)
Effluent quality of the present invention is better than reverse osmosis water outlet, technology maturation is reliable, and auxiliary water ratio is generally 5%, and reverse osmosis system auxiliary water ratio reaches 25%, if it is 100t/h that Boiler water Feeding System system is exerted oneself, reverse osmosis system is than ion exchange system many water consumptions 20t/h per hour, and 10 yuan/ton of the service waters of take are example, many 200 yuan of water producing cost per hour, therefore with respect to reverse-osmosis treated, energy consumption is low, has good economy, in water-deficient area, is worth of widely use especially.
