Description

Spent lye in a kind of LCD production process and acid mist treatment system
Technical field
The utility model relates to a kind of system that spent lye and acid mist are purified, processed of the LCD of being applied to production field.
Background technology
At present, a lot of industries all will be used acid, acid becomes the indispensable raw material of some operation, in pickling, removal of impurities etc. step, all can use acid, since can use acid, in use inevitably will produce acid mist, the acid mist that workshop produces can corrode workshop steel structure, etching mechanism equipment and instrument and meter, acid mist is toxic gas to people simultaneously, sucks too much and can produce injury greatly to people's health, and be directly released in air, pollutes the environment.At present at LCD production field, to the processing of acid mist, be to adopt in acid mist tower by the manual mode that directly adds finished product NaOH, discharge after air is up to standard, adopt and add NaOH as upper type just needs every day, it is very inconvenient to operate, and the exhaust outlet of acid mist tower tends to, because NaOH easily lumps and blocks, affect exhaust.
Meanwhile, in LCD technological process, there are some steps to clean glass substrate and to remove the glue, film etc. of various coatings with alkaline solution, the alkaline solution of this part is directly discharged in waste liquid pool by spent lye conveying pipeline after using often, now the spent lye ph value in waste liquid pool is higher, cause Sewage Disposal need to add more acid and neutralize, make processing cost higher.
Utility model content
The purpose of this utility model is to provide spent lye and the acid mist treatment system in a kind of LCD production process, and the spent lye and the acid mist processing cost that solve in existing LCD technological process are high, the problem wasting time and energy.Overall process is controlled water pump by ph value controller and is realized auto feed, does not need manual intervention, and improvement cost is low, and has avoided spent lye directly to discharge the waste causing, realistic Production requirement.
The utility model solves the technical scheme that its technical problem adopts: the spent lye in a kind of LCD production process and acid mist treatment system, comprise the conveying pipeline that fills spent lye of drawing from workshop, and waste liquid pool and acid mist tower, be provided with dosing tank on acid mist tower; Also comprise the spent lye collecting pit being connected with conveying pipeline, this collecting pit is connected with the dosing tank of acid mist tower by water pump, and ph value controller is also installed in acid mist tower, and this ph value controller is electrically connected to water pump.Preferably, spent lye is NaOH solution.Adopt said structure to solve traditional acid mist processing cost high, the problem that is difficult for exhaust, the spent lye that workshop is discharged is first discharged in the collecting pit installing additional, and is connected with acid mist tower by water pump, in acid mist tower, arrange a ph value controller, and this ph value controller is electrically connected to water pump simultaneously.Ph value in acid mist tower is lower than when setting value, and ph value controller is controlled pump working, by the dosing tank of the spent lye suction acid mist tower in collecting pit, realizes auto feed, and overall process does not need manual intervention, and improvement cost is low.
In order to prevent that the spent lye in suction acid mist tower from diffusing out, as further improvement of the utility model, between acid mist tower and waste liquid pool, be also provided with overflow pipe.Now enter the waste liquid of waste liquid pool than the spent lye of directly discharging from workshop, its ph value obviously reduces, and has reduced the processing cost of Sewage Disposal.
The beneficial effects of the utility model: the utility model is first discharged in the collecting pit installing additional by the spent lye that workshop is discharged, and collecting pit is connected with acid mist tower by water pump, in acid mist tower, arrange a ph value controller, and this ph value controller is electrically connected to water pump simultaneously.Ph value in acid mist tower is lower than when setting value, ph value controller is controlled pump working, by in the dosing tank of the spent lye suction acid mist tower in collecting pit, realize auto feed, overall process does not need manual intervention, and improvement cost is low, and the spent lye and the acid mist processing cost that have solved in existing LCD technological process are high, the problem wasting time and energy, the demand of realistic production.
Accompanying drawing explanation
Below with reference to drawings and Examples, the utility model is described in detail.
Fig. 1 is the system block diagram that the spent lye in existing LCD technique and acid mist are processed described in background technology.
Fig. 2 is fundamental diagram of the present utility model.
In figure: 1, conveying pipeline; 2, collecting pit; 3, waste liquid pool; 4, acid mist tower; 5, dosing tank; 6, water pump; 7, ph value controller; 8, overflow pipe; 3 ', improve front existing waste liquid pool; 4 ', improve front existing acid mist tower; 5 ', improve front existing dosing tank.
The specific embodiment
Embodiment, refers to Fig. 2, and the spent lye in a kind of LCD production process and acid mist treatment system comprise the conveying pipeline that fills NaOH solution 1 of drawing from workshop, the spent lye collecting pit 2 being connected with conveying pipeline 1, waste liquid pool 3 and acid mist tower 4.Wherein, waste liquid pool 3 is understood in automatic acid adding and NaOH, and acid mist tower 4 is that acid gas is neutralized with NaOH.
On acid mist tower 4, be provided with dosing tank 5.Collecting pit 2 is connected with the dosing tank 5 of acid mist tower by water pump 6, and ph value controller 7 is also installed in acid mist tower 4, and this ph value controller 7 is electrically connected to water pump 6.Between acid mist tower 4 and waste liquid pool 3, be also provided with overflow pipe 8.Above-mentioned NaOH solution, for the useless NaOH solution after using, wherein contains impurity, and integral body is alkalescence.
During use, the ph value in ph value controller monitoring acid mist tower, the ph value in acid mist tower is when setting value, and ph value controller control pump working, by the dosing tank of the NaOH solution suction acid mist tower in spent lye collecting pit, realizes auto feed.Waste liquid in acid mist tower is during higher than overfall, and waste liquid is discharged from overflow pipe, converges to waste liquid pool.The utility model does not need manual intervention, and overall process is added automatically, and does not need finished product NaOH, time saving and energy saving, and the ph value concentration of the useless NaOH solution of simultaneously also workshop being discharged has reduced, and has reduced the processing cost of Sewage Disposal.
The above is only to preferred embodiment of the present utility model; not scope of the present utility model is limited; therefore do not departing under the prerequisite of the utility model design spirit; the equivalence that those of ordinary skills do structure described in the utility model, feature and principle changes or decorates; as above-mentioned NaOH solution is replaced to other alkaline solutions; acid mist tower dosing tank is not set separately but directly and water pump join etc., all should fall in protection domain of the present utility model.
