Working principle:
Sodium chlorate electrolysis production process the following steps are included:
1, the adjusting of pH and temperature are carried out before output of products to electrolyte:
The automatically controlled flow valve 18 of product is closed, circulation electrically-controlled valve 11 is opened, after electrolysis reactor 6 is driven, electrolyte is made first to exist
It is recycled between electrolysis reactor 6, electrolyte surge tank 7 and de- hypochlorous acid reactor tank 8, without output of products, to electrolyte
PH and temperature are adjusted.
Dilute hydrochloric acid enters the end of sodium chloride solution conveyance conduit 1 by dilute hydrochloric acid conveyance conduit 2, mixed with sodium chloride solution
It is conveyed by variable-frequency delivery pump 3 into cooler 4 after conjunction and carries out temperature adjustment, the mixed solution after temperature adjustment reaches sodium chloride solution delivery pipe
The end in road 1, pH sensor 5 detects the pH of mixed solution, and measured value is transferred to PLC controller 19, temperature sensor
25 detect the temperature value of mixed solution, and measured value is transferred to PLC controller 19；It is set when pH is greater than in PLC controller 19
When fixed maximum value 6.0, PLC controller 19 tunes up signal to automatically controlled 14 transmitted traffic of flow valve of dilute hydrochloric acid, when pH is controlled less than PLC
When the minimum value 5.8 set in device 19 processed, PLC controller 19 turns signal down to automatically controlled 14 transmitted traffic of flow valve of dilute hydrochloric acid, the
The flow value of dilute hydrochloric acid is conveyed to PLC controller 19 by flow meters 13, and the addition of dilute hydrochloric acid is monitored convenient for PLC controller 19
Amount, judges the regulated quantity of the automatically controlled flow valve 14 of dilute hydrochloric acid；When temperature value is greater than the maximum value set in PLC controller 19, PLC
Controller 19 tunes up signal to 24 transmitted traffic of cooling water electrically-controlled valve, when temperature value is less than the minimum set in PLC controller 19
When value, PLC controller 19 turns signal down to 24 transmitted traffic of cooling water electrically-controlled valve.Mixed solution is from sodium chloride solution conveyance conduit
After 1 discharge, cell reaction is carried out into electrolysis reactor 6, the electrolyte after reaction enters the race way of electrolyte surge tank 7,
Product density after electrolysis is less than the electrolyte not being electrolysed, therefore product overflow of the product in the top of race way, race way
To the product zone of electrolyte surge tank 7, de- hypochlorous acid reactor tank 8 is entered back into, product zone is finally recycled back to；It is not electric in race way
It is again introduced into sodium chloride solution conveyance conduit 1 after the electrolyte discharge of solution and the mixed solution of 3 arrival end of variable-frequency delivery pump carries out
Mixing repeats above-mentioned temperature and adjusts and pH adjusting.
2, the pH of electrolyte and temperature, which meet after electrolysis requires, carries out output of products:
After the pH and temperature of electrolyte, which meet electrolysis, to be required, the automatically controlled flow valve 18 of product is opened, closes circulation electrically-controlled valve
11, carry out output of products.The aperture that the automatically controlled flow valve 18 of product is adjusted by product consumption, to control output of products amount.
At this point, the electrolyte in the race way of electrolyte surge tank 7 produces after mixing with the crystalline mother solution that subsequent product processing equipment returns
Product overflow to product zone by the overflow port on weir divider top, into de- hypochlorous acid reactor tank 8 in carry out de- hypochlorous acid reaction
Then subsequent product processing equipment is discharged by product channels 9, the electrolyte and crystalline mother solution that lower part is not electrolysed pass through the
One circulating line 12 is mixed with dilute hydrochloric acid and sodium chloride solution into sodium chloride solution conveyance conduit 1, temperature adjustment, adjusts pH, most
Enter electrolysis reactor 6 afterwards and carry out cell reaction, the electrolyte after cell reaction enters race way and the knot of electrolyte surge tank 7
After brilliant mother liquor mixing, a part is used as output of products, and a part mixes with dilute hydrochloric acid and sodium chloride solution, continues to be electrolysed.
3, when pH sensor or the automatically controlled flow valve of dilute hydrochloric acid break down, the pH of electrolyte is adjusted:
When pH sensor 5 or the automatically controlled flow valve 14 of dilute hydrochloric acid break down, when can not carry out the automatic monitoring and regulation of pH, close
It closes defective valves and opens dilute hydrochloric acid hand control valve 21, switching dilute hydrochloric acid is added channel, enables backup line 20, dilute hydrochloric acid directly adds at this time
The race way for entering electrolyte surge tank 7 is mixed with the electrolyte in race way, expands blending space, so that dilute hydrochloric acid
It is more fully mixed with electrolyte；It is sampled in the outlet end of sodium chloride solution conveyance conduit 1 by probe tube 23, to sample
PH value artificial detection is carried out, and manually adjusts dilute hydrochloric acid hand control valve 21 according to testing result.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
