Quenching column top is provided with spray equipment 29, and the centre is filled with filler 29.The heat-eliminating medium of quenching column 2 is thick bamboo vinegar liquid, and equipment uses the thick bamboo vinegar liquid of a spot of outsourcing when just having started, and circulation can be satisfied the circulation requirement from the bamboo vinegar liquid of interchanger 3 after starting.Pass through the quenching column bamboo vinegar liquid steam-in 21 entering quenching columns of quenching column 2 from the residue bamboo vinegar liquid steam of cooling tower bamboo vinegar liquid vapour outlet 12 discharges; Be further cooled; Be reduced to 75 ℃ by 110 ℃; Collect outlet 22 from the quenching column second bamboo vinegar liquid product again and discharge, get into the second bamboo vinegar liquid product storage tank 6.The thick bamboo vinegar liquid of heat-eliminating medium; Get into quenching column 2 from quenching column bamboo vinegar liquid inlet 23, utilize spray equipment 29, fully contact its cooling with bamboo vinegar liquid steam betwixt in filler 28 parts; In the refrigerative process; Its temperature is lifted to 75 ℃, and the bamboo vinegar liquid after the temperature rising is discharged through quenching column bamboo vinegar liquid outlet 24 again, gets to interchanger bamboo vinegar liquid inlet 32 entering interchanger 3 by recycle pump 5 and carries out heat exchange operation.The top of quenching column 2 is provided with quenching column vapour outlet 25, is used for discharging uncooled gas, and these gases comprise H
2, CO, N
2, CH
4, H
2O etc.The pipeline that said quenching column 2 top quenching column vapour outlets 25 link to each other is provided with quenching column TP 26, and controlled chilling tower temperature control valve 261 (adjustable valve) are according to the spray flux of quenching column 2 overhead vapor temperature adjustment bamboo vinegar liquid; When temperature surpasses 115 ℃; Increase the aperture of valve 261, increase spray flux, when temperature during less than 105 ℃; Reduce the aperture of valve 261, reduce spray flux.Complete to guarantee the components condense in the bamboo vinegar liquid.Quenching column 2 set inside one quenching column leve monitor 27, control level control valve door 271 (standard-sized sheet full cut-off valves) are used for regulating the height of liquid level in the quenching column, and liquid level is remained on about 60%.Concrete, but the control of leve monitor 27 computers, when liquid level is higher than 70%; Liquidometer 27 is reported to the police, and bleed valve is opened automatically, thick bamboo vinegar liquid from the quenching column side pipeline 22 discharge automatically; When being disposed to liquid level to 60%, close automatically, keep a steady state with the liquid level of keeping in the quenching column.
Interchanger 3 is connected with quenching column 2 through recycle pump 5, and interchanger adopts tube and shell heat exchanger, and heat-eliminating medium is a water, and said recycle pump 5 adopts impeller pump.The heat exchange bamboo vinegar liquid that comes out from quenching column bamboo vinegar liquid collection outlet 22 is pumped into the interchanger 3 through recycle pump 5, in interchanger 3, is condensed to 54 ℃, discharges from interchanger bamboo vinegar liquid outlet 31, can get into the quench liquid use of circulation as quenching column 2.And the heat-eliminating medium water coolant gets into interchanger 3 by interchanger cooling water inlet 33, after heat exchange, discharges via interchanger cooling water outlet 34.Wherein interchanger also can be provided with heat exchange temperature inductor block 35 in interchanger bamboo vinegar liquid outlet 31, the interchanger temperature control valve 351 (adjustable valve) of its controlled chilling water inlet pipeline, and keeping the temperature of cooled bamboo vinegar liquid with the flow through controlled chilling water is 54 ± 5 ℃; Promptly when temperature is increased to 59 ℃; Increase the aperture of valve 351, increase cooling water flow, when temperature is reduced to 49 ℃; Reduce the aperture of valve 351, reduce cooling water flow.
Through above step; The amount that from cooling tower, obtains the first bamboo vinegar liquid product sample 1 is 30%; The amount that from quenching column, obtains the second bamboo vinegar liquid product sample 2 is 70%, and the composition of each sample of method mensuration is as shown in table 3 below, and the organic acid content of sample 1 accounts for major part; Contain organic acid in the sample 2 hardly, can know and adopt the equipment of the utility model to make the initial gross separation of bamboo vinegar liquid product open.
Table 3
Adopt the recovery method of the equipment of the utility model; Evaporation efficiency and bamboo vinegar liquid collection rate all are improved; Evaporation efficiency has reached more than 90%, and the collection rate of bamboo vinegar liquid is greater than 95%, and adopts the evaporation efficiency of art methods that water directly sprays the bamboo vinegar liquid steam cooling less than 80%; The bamboo vinegar liquid collection rate all has no small gap with the utility model less than 80%.
Though the equipment of the utility model is than the complicacy of prior art; Seem that separation costs is high, yet in the long term, because this equipment has been realized initial gross separation for the bamboo vinegar liquid that with the organic acid is the master; The cost that later stage is separated useful prods to be needed has obtained significantly reducing; And opposite, the method for prior art need expend higher cost in the later stage and remove to separate the products such as organic acid that mix, and cost is high all the better.
