Description
Technical field
The present invention relates to chemical production fields more particularly to a kind of continuous combination reaction of barium sulfate and reaction end to examine automatically
Survey device and method.
Background technique
Concentration is mainly 12%-14% barium sulfide solution and concentration 25%--27% sodium sulphate by barium sulfate combination reaction
Solution carries out metathesis reaction in chemical combination tank, generates the reaction process of barium sulfate and vulcanized sodium.Reactional equation is as follows:
BaS+Na2SO4=BaSO4+Na2S,
Domestic main large-scale production enterprise all chemical combination processes all use the intermittent tissue of combination reaction kettle for a long time
Production.The technology produced using serialization symphysis is never made a breakthrough for decades.Causing the basic reason of this situation is
Chemical combination terminal uses always manual discontinuous sample detection, and the continuous endpoint technique that detects fails to obtain breakthrough.Greatly
Limit the application to mechanization, automation and informationization of chemical combination process.
Intermittent reaction, manual inspection terminal method be: to empty reactor tank and meanwhile be added 12% -14% barium sulphide and
With 25%--27% metabisulfite solution, feed while stirring.When being added to the 1/2 of tank internal volume, start to survey terminal by hand.Side
Method is to dip reaction slurry, is filled into two clean test tubes with funnel and qualitative filter paper.Into test tube, lye is added dropwise respectively
10% metabisulfite solution and 10% barium sulfide solution.Whether there is or not white opacity generations for lye in observation test tube.If sodium sulphate is added dropwise
Muddiness is generated, illustrates that barium sulphide is excessive in slurry, then requires supplementation with addition sodium sulphate., whereas if barium sulphide is added dropwise in test tube
There is white opacity, then illustrates sodium sulphate excess, require supplementation with barium sulphide.So reaction addition is found, until being added any one
, there is not muddiness in kind of detection agent, then to be reacted to terminal (being commonly called as " two is clear ").This is the process of a continuous trial and error, until
It adjusts and completes.Often there is material in tank and fills it up with the case where still can not find terminal.
The drawbacks of manual inspection terminal is clearly:
1, charging charging process is similar to " blind operation ", only leans on subsequent manual inspection, and efficiency is very low；
2, the examined personnel's subjective factor of manual inspection and sense of responsibility influence very big, it is difficult to guarantee that every batch of product is all reacted to
Terminal, when reacting end of a period, sodium sulphate is excessive, then akali sulphide product iron ion increases, and color reddens, quality degradation, if
Barium sulphide is excessive, then the barium that dissociates in barium sulfate product severely exceeds, and causes product unqualified；
3, intermittent operation material residence time in each tank is different, and amount of cure is different, the interstitial of product batches
Amount fluctuation is very big；
4, when intermittent operation, due to feeding every time, material is more by few change in tank, and volume of material rises steadily, for one
For the barium sulphide or sodium sulphate charging rate of a fixation, raw material be added tank in moment concentration distribution gradient be in variation,
The variation of concentration distribution gradient brings the variation of reaction speed, and being changed significantly for reaction speed influences the change of barium sulfate product partial size
Change.
In the above-mentioned methods, test and production practices all confirm, in intermittent reaction tank, since raw material is in tank when initial charge
Interior concentration gradient is big, and reaction speed is fast, and partial size is smaller, and as material increases in tank, the raw material liq of constant inflow is by tank
Material stock " dilution ", concentration gradient becomes smaller, and partial size increases.Therefore the barium sulfate product particle diameter distribution that intermittent reaction obtains is wide in range,
Quality is lower.
For a long time this situation fail take on a new look the reason of be:
It 1, is to roast to generate using barite deposit, since barite deposit quality is continuous due to material liquid especially barium sulphide
Fluctuation, roasting condition stability is difficult to absolutely control, therefore barium sulphide content is between 12% -14% always and fluctuates, can not
It is accurately controlled, identical flow cannot be guaranteed barium sulphide stable components therein, this is that operational characteristic determines.Due to sulphur
Change barium solution and be easy fouling, exact level measurement can not be carried out to it using fine instrument；
2, barium sulfate reaction is a reaction process to terminal and its sensitivity, in a 30m3Chemical combination tank in, terminal
At the end of, even if terminal can all shift, and influence product matter in addition 500-800g raw materials (sodium sulphate or barium sulphide)
Amount, the requirement to precision have reached 3/100000ths, have been capable of providing such precision currently without any online monitoring instruments.
