Description
[technical field]
The present invention relates to a kind of six tower thermopnore de-mineralized water equipment.
[background technology]
Existing market upper level de-mineralized water equipment; Still adopt the sun bed and the cloudy bed apparatus of fixed-bed type; Manually-operated gate is still used in its operation, regeneration, cleaning, and that is afraid of to adopt the automatic valve operation, after cationic, anionic exchange resin is saturated; Also need stop bed and regenerate, clean, must adopt two cover positive and negative bed apparatus hocket regeneration, cleaning if produce water continuously.So, must double investment, administer and maintain expense.
[summary of the invention]
Technical purpose of the present invention is, for solving the problem of above-mentioned existence, and a kind of six brand-new tower thermopnore de-mineralized water equipment is provided, and it can collect the sun bed-degassing-regeneration-cleaning; The one-level de-mineralized water equipment of cloudy bed-regeneration-cleaning.
The six tower thermopnore de-mineralized water equipment that the present invention proposes pass through exchange-regeneration-cleaning-exchange cycles flow process by two cover positive and negative bed apparatus and just realize ceaselessly production one-level de-mineralized water automatically, need not stop bed regeneration and cleaning in whole product water process; Have closing valve only to play first the effect of debugging, in operation-regeneration, cleaning process without operated valve.
The exchange current movable bed de-mineralized water equipment that the present invention proposes; Its main characteristics is: former water flooding quantity, regenerator acid, alkali lye inlet, rinse water flushing dose all carry out through the under meter metering, realize environmental protection and energy saving, to guarantee its accuracy; Validity, operation easily again.
Programmable logic controller is through the water level monitoring to 1# exchange column 4 air-water separation chambers 3.Greater than water inlet, when water level arrived the warning position, programmable logic controller was closed into water water pump and gas blower as if middle force (forcing) pump pushing quantity, and force (forcing) pump is delivered to the decline of 2# exchange column 9 water levels to water in the middle of opening; When arriving ordinary water-level, programmable logic controller is opened into water water pump and gas blower simultaneously; When water level continue to descend, programmable logic controller is closed middle force (forcing) pump when dropping to water level under the warning position, does not rise because of there being the water outlet cistern water level at once; Rise to ordinary water-level, force (forcing) pump was delivered to 2# exchange column 9 to water and is so circulated in the middle of programmable logic controller was opened.If middle force (forcing) pump pushing quantity is during less than flooding quantity, programmable logic controller is through the open and close of control water inlet water pump and gas blower, lets in the unit time water yield of access device approaching identical.After valve and automatically controlled debugging were good, automatically controlled action was less, mainly is to play safety effect in principle.
[description of drawings]
Below in conjunction with the embodiment accompanying drawing, the present invention is described further.
Fig. 1 is single shell type fixed bed de-mineralized water equipment elevational schematic view.
Fig. 2 is six tower thermopnore de-mineralized water equipment elevational schematic view.
[embodiment]
Below in conjunction with accompanying drawing the present invention is done further explanation:
Existing fixed bed one-level de-mineralized water equipment drawing 1 adopts the cloudy bed 4 of fixed bed sun bed 1 polyphone, and the sun bed is gone up water inlet 2 during operation, following water outlet 3, the cloudy bed 4 of polyphone, on intake 5, following water outlet 6 output one-level de-mineralized waters.Technology is operation-saturated-stop bed-regeneration-cleanings-operation, generally adopts the valve manual operation, also have small portion to adopt the automatic valve operation, but investment is expensive, so owing to being that fixed bed also need stop bed to regenerate, cleaning.Will adopt a cover fixed bed operation if produce water continuously, and another set of fixed bed is regenerated, cleaned back is subsequent use, promptly one applies mechanically the subsequent use technology setting of a cover.
The six tower thermopnore de-mineralized water equipment that the present invention proposes, its structure is as shown in Figure 2, and it is mainly by independently cationic exchange thermopnore three towers and anionresin thermopnore three towers, acid, alkali regenerator system, electric control gear are formed.
Zeo-karb fills in the 1# exchange column 4; Tap water or the water that is equivalent to the tap water degree of purification are metered into through under meter 1 at the bottom of tower; Exchange with cation exchange resin layer 4; Decationizing water gets into decarbonizer 2 from cat head and removes dioxide gas, gets into 3 pairs of gases of air-water separation chamber again and does last the separation, pressurizes input 2# exchange columns 9 bottoms as water inlet at the decationizing water that does not have carbonic acid gas and gas by in-line pump 8; Cation exchange resin layer 4 exchanges the sedimentation downwards of saturated back with water inlet; And get into regenerator column 5 with potential difference and regenerate and pre-washing; Getting into cleaning tower 6 with potential difference again cleans completely; By resin injector 7 the positive resin of new life is sent in exchange column 4 top at last, carried out the water that uniform distribution and adverse current make progress by the resin distribution device and exchange.Form the closed circuit flow circuit technology of an exchange-regeneration-cleaning-exchange.
Anionite-exchange resin fills in the 2# exchange column 9; Decationizing water gets into 2# exchange column 9 interior adverse currents upwards by in-line pump 8 pressurizations; Exchange the sedimentation downwards of saturated back with anionite-exchange resin, and regenerate and pre-washing, get into cleaning tower 11 with potential difference again and clean completely with potential difference entering regenerator column 10; By resin injector 12 newborn negative resin is sent in exchange column 9 tops at last; Carry out the decationizing water that uniform distribution and adverse current make progress by the resin distribution device and exchange, form the closed circuit flow circuit technology of an exchange-regeneration-cleaning-exchange, eject the mouth of a river 13 output one-level de-mineralized waters by 2# exchange column 9 at last.
The present invention's six tower thermopnore de-mineralized water equipment; Operation-the degassing-regeneration-cleaning-operation is by potential difference and automatically controlled realization robotization; Do not need manual operation; All valves all are used in the difference of the subscriber-related different quality parameter in various places, water temperature difference and debug use first, and equipment can drop into automatic running status through debugging after good fully.
