5. qualified acid solution after analysis is put into and deposit sour tank in order to producing.
Compared with prior art, beneficial effect of the present invention is: reclaim acid recycling, circulate successively, make cost comparatively cheap, can accurately detect the concentration of composition in spent acid and nitration mixture, can be used for recovery and the detection of spent acid or new mixture, applied range.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention;
Fig. 2 is control panel of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1-2, sour feeding mechanism system of the present invention, comprises raw acid storage unit 1, spent acid recovery unit 2, new mixed unit 3 processed and analyzes detecting unit 4.
Raw acid storage unit 1 comprises more than 2 ortho acid holding vessels 11, spent acid recovery unit 2 comprises more than 2 and reclaims sour holding vessel 21 and more than 1 filter 23, the mixed unit 3 processed of eo-acid comprises more than 2 mixture tanks 31, analyzes detecting unit 4 and comprises more than 1 concentration analyzer 41.
Ortho acid holding vessel 11 and reclaim sour holding vessel 21 and be connected with pipeline with between mixture tank 31, mixture tank 31 is connected with concentration analyzer 41 pipeline.
Raw acid storage unit 1, spent acid recovery unit 2, eo-acid mix unit 3 processed and analyze on all pipelines between detecting unit 4 and be provided with several valves,
By reclaim in ortho acid holding vessel 11 in raw acid storage unit 1 and spent acid recovery unit 2 sour holding vessel 21 by pipeline separately the mixture tank 31 mixed with eo-acid in unit 3 processed be connected, in mixture tank 31, preparation eo-acid is carried out according to different need of productions, be connected with the concentration analyzer 41 analyzed in detecting unit 4 by pipeline after eo-acid preparation, extraction and analysis sample is controlled by pump and automatic valve, sample is by concentration analyzer 41 automatic analysis, automatically analytic liquid can be pumped into through measuring pump in analytic process, analytic liquid and example reaction, the concentration analyzing sample is detected by automatic detecting electrode, automatically start to analyze acid solution constituent concentration after mixture, analyze qualified after newly mixed relieving haperacidity is squeezed into by pipeline deposit sour tank 32, in order to production and application again.
When the waste acid liquor of chemical workshop is got rid of with spent acid discharge tube, first be discharged in spent acid holding vessel 22, spent acid holding vessel 22 has more than 2, spent acid holding vessel 22 is connected by pipeline with filter 23, through filter 23, be connected to pipeline and reclaim sour holding vessel 21, reclaim sour holding vessel 21 and be connected by pipeline with new mixed unit 3 processed.
In spent acid recovery unit 2, Water demand detects device 23 after filtration and is placed on the composition reclaiming acid solution in sour holding vessel 21 after processing, analytic process is the same, ortho acid is injected mixture tank 31 with recovery acid and carries out mixture by ratio needed for calculating according to system automatic analysis subsequently successively, and whether analyze detection acid solution composition up to standard, finally put into and deposit sour tank 32, in order to production and application, circulate successively, applied range.
