The viscose pickling post-processing device has the advantages of being low in cost, high in automation degree and simple to operate, the pickling site environment is greatly improved, the physical and psychological health of workers is protected, the operation safety is high, the PH value is controlled to be stable, and adverse effects caused by pickling on the product quality are greatly reduced.
Description
Technical field
The utility model relates to a kind of viscose pickling after-treatment device.
Background technology
The post processing of viscose will be through overpickling, by the acid solution rinsing to regulate the fiber pH value.At present, acetic acid is adopted in conventional pickling, and at first acetic acid cost height, and excitant is strong, causes production environment abominable. and bring potential safety hazard to the site operation personnel, and acetic acid is 16.6 ℃ in freezing point in addition, freezes under the low temperature to cause to use difficulty.
The utility model content
Its purpose of the utility model just is to provide a kind of viscose pickling after-treatment device; have the advantages that cost is low, automaticity is high, simple to operate; and the pickling site environment is greatly improved; protection employee physical and mental health; safety operation is strong; pH value control is stable, significantly reduces pickling to the adverse effect of product quality.
The technical scheme that realizes above-mentioned purpose and take, comprise the refining descaling bath, also comprise concentrated sulfuric acid head tank, the outlet of concentrated sulfuric acid head tank connects the dilute sulfuric acid surge-tank through switch valve, dilute sulfuric acid surge-tank upper end is provided with the allotment hose, and described dilute sulfuric acid surge-tank outlet connects the dilute sulfuric acid accumulator tank through allocating valve in parallel, and the outlet of dilute sulfuric acid accumulator tank connects the pickling circulating slot through circulating pump, the outlet of pickling circulating slot connects the refining descaling bath through the valve in parallel that circulates, and the outlet of refining descaling bath connects the pickling circulating slot.
Compared with prior art the utlity model has following advantage.
Use sulfuric acid to replace acetic acid, the cost of raw material significantly reduces; Employing automatic interlock control, the automaticity height, technological operation is simple; The pickling site environment is greatly improved, protection employee physical and mental health; Select for use the material corrosion resistance strong, safety operation is strong.PH value control is stable, significantly reduces pickling to the adverse effect of product quality.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this apparatus structure schematic diagram.
The specific embodiment
Comprise refining descaling bath 9, as shown in Figure 1, also comprise concentrated sulfuric acid head tank 1,1 outlet of concentrated sulfuric acid head tank connects dilute sulfuric acid surge-tank 4 through switch valve 3, dilute sulfuric acid surge-tank 4 upper ends are provided with allotment hose 5, and described dilute sulfuric acid surge-tank 4 outlets connect dilute sulfuric acid accumulator tank 6 through allocating valve 13 in parallel, and 6 outlets of dilute sulfuric acid accumulator tank connect pickling circulating slot 8 through circulating pump 11,8 outlets of pickling circulating slot connect refining descaling bath 9 through the valve 13 in parallel that circulates, and 9 outlets of refining descaling bath connect pickling circulating slot 8.
Described switch valve 3 connection traffic meters 2.
Be provided with by-passing valve 12 between described circulation valve 13 outputs in parallel and the dilute sulfuric acid surge-tank 4.
Described pickling circulating slot 8 is provided with pickling hose 7.
Described dilute sulfuric acid surge-tank 4, dilute sulfuric acid accumulator tank 6 and pickling circulating slot 8 are provided with liquid level gauge 14.
This device is with comprising dilute sulfuric acid mixing system, dilute sulfuric acid stocking system, the pickling circulatory system.Dilute sulfuric acid mixing system use traffic meter, liquid level gauge, switch valve adopt automatic interlock by DCS operator's policer operation, the automaticity height, and allotment dilute sulfuric acid concentration is accurate, utilizes the stability of technology controlling and process.
1, dilute sulfuric acid allotment: prepare dilute sulfuric acid surge-tank 4 liquid levels at every turn and be set in certain liquid level, add quantitative 98% the concentrated sulfuric acid.Soft water pneumatic operated valve on the allotment hose 5 is opened, and the soft water pneumatic operated valve cuts out automatically when the soft water addition reaches the setting liquid level.Start circulating pump 11 and walk interior circulation, the concentrated sulfuric acid adds.Switch valve 3 will cut out automatically when concentrated sulfuric acid addition reaches setting value.After the concentrated sulfuric acid adds, interior circulation termination of pumping about 10 minutes, standby.
2, dilute sulfuric acid is transported to accumulator tank:
Because sulfuric acid is different with the proportion of water, long meeting standing time causes density unevenness even, fully mixes so circulate in beating earlier before conveying.After the circulation, after circulation 10-15 minute, interior circulating valves are switched to carrying in the dilute sulfuric acid accumulator tank in the ON cycle pump in earlier the circulating pump pipeline valves being switched to, entered and add.
3, pickling circulation:
By the measuring pump accurate quantification add dilute sulfuric acid to the pickling circulating slot, circulating pump 11 is got to refining with acid water and product is carried out PH is regulated.
