Compared with the prior art, the utility model has the advantages of water cycle, automatic control are traded in healthy environmental protection, extension.
Description
Technical field
The utility model is related to a kind of acid mist tower, especially relates to a kind of acid mist tower for electroplating workshop exhaust-gas treatment.
Background technology
Plate-making row electroplating workshop at this stage, is all to reduce using air exhauster system exhausting to produce during processing in process of production
Raw waste gas, it is to avoid the workshop condition pollution effect that waste gas causes.But because direct exhausting will also result in air to outside environment
Pollution, due to being all that the waste gas that acid electroplating extraction is gone does not reach environmental requirement containing acidity at present, the feelings using in acid waste gas
Under condition, cold air can produce globule acid water and can increase and equipment be caused corrode.
Utility model content
The purpose of this utility model be exactly provide to overcome the defect that above-mentioned prior art exists a kind of health environment-friendly,
The acid mist tower for electroplating workshop exhaust-gas treatment extend exchange water cycle, automatically controlling.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of acid mist tower for electroplating workshop exhaust-gas treatment, fills including tower body and the pond being located in tower body, spray
Put, gas inlet passage, exhaust passage, alkaline doser and controller, be provided with ph value measuring probe in described pond, described
Controller be connected with ph value measuring probe and alkaline doser respectively.
Described alkaline doser is NaOH doser.
It is provided with water circulating pump and hydrops reflux in described pond.
Described alkaline doser includes grug feeding jar, battery valve and dosing pipe, and described grug feeding jar passes through dosing pipe
It is connected with pond, described magnetic valve is located on dosing pipe, and is connected with controller.
Described controller is Programmable Logic Controller.
Described gas inlet passage is provided with air exhauster.
Compared with prior art, the utility model has the advantage that
1) health environment-friendly, reduces the acidity of filter water, it is to avoid equipment is caused corrosion shorten service life of equipment, simultaneously right
Discharge after the waste gas of environmental pollution is up to standard；
2) extend exchange water cycle, from the acid ion in NaOH and in water, hydroxide ion and copper ion occur
Reaction generates Kocide SD particulate matter, and this particulate matter has suction-operated to the other impurity in filter water, thus accelerating in water
Contamination precipitation, to the speed of spray basin bottom, also makes filter water be purified, and extends the replacement cycle extending water；
3) automatically control, real-time monitoring, setting range, ph value are carried out by ph value measuring probe to shower water Acidity
Measuring probe is attached by holding wire and Programmable Logic Controller, then is completed to sodium hydroxide solution grug feeding jar by controller
The solenoid valve control of pipeline.
Brief description
Fig. 1 is structural representation of the present utility model.
Wherein 1 is tower body, 2 is gas inlet passage, 3 is exhaust passage, 4 alkaline dosers, 5 be controller, 6 be ph value
Measuring probe, 7 be water circulating pump, 8 be hydrops reflux, 9 be air exhauster.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely description is implemented it is clear that described embodiment is a part of embodiment of the present utility model, rather than all
Example.Based on the embodiment in the utility model, those of ordinary skill in the art institute on the premise of not making creative work
The every other embodiment obtaining, all should belong to the scope of the utility model protection.
As shown in figure 1, a kind of acid mist tower for electroplating workshop exhaust-gas treatment, including tower body 1 and be located in tower body
Pond, spray equipment, gas inlet passage 2, exhaust passage 3, alkaline doser 4 and controller 5, are provided with ph in described pond
Value measuring probe 6, described controller 5 is connected with ph value measuring probe 6 and alkaline doser 4 respectively；
Waste gas, after gas inlet passage 2 enters tower body, passes through exhaust after being contacted with the water of spray equipment ejection
Passage 3 is discharged, the ph value in described ph value measuring probe 6 real-time monitoring water, when ph value is less than and sets minimum threshold, described
Controller 5 control the dosing of alkaline doser 4, and when ph value is more than the max-thresholds setting, described controller 5 controls alkali
Property doser 4 stop dosing.
Described alkaline doser 4 is NaOH doser.It is provided with water circulating pump 7 and hydrops backflow in described pond
Device 8.Described alkaline doser 4 includes grug feeding jar, battery valve and dosing pipe, described grug feeding jar pass through dosing pipe with
Pond connects, and described magnetic valve is located on dosing pipe, and is connected with controller.Described controller is PLC technology
Device.Described gas inlet passage is provided with air exhauster 9.
Through test of many times, improving new technique, carrying out processing acid ion in waste gas from acid mist tower.Can effectively drop
Acid waste gas in low waste gas, reduce the corrosion to equipment；Filtered in water using waste gas, because waste gas sprays from water simultaneously
Acid ion is brought in pouring the inside of feeding water, and we select the acid ion in NaOH and in water, hydroxide ion and copper from
Son reacts and generates Kocide SD particulate matter, and this particulate matter has suction-operated to the other impurity in filter water, thus plus
Fast impurities in water is deposited to the speed of spray basin bottom, so that filter water is purified, and extends the replacement cycle extending water.
After the utility model, compared with prior art, there is advantage in detail below, as shown in table 1:
Table 1
The above, specific embodiment only of the present utility model, but protection domain of the present utility model does not limit to
In this, any those familiar with the art, in the technical scope that the utility model discloses, can readily occur in various
Equivalent modification or replacement, these modifications or replacement all should be covered within protection domain of the present utility model.Therefore, this practicality
New protection domain should be defined by scope of the claims.
