2) the device of automatically detects the absorption liquid PH value, and at the same time automatically add alkali liquor.
3) A group of inlet and outlet pipes
3. Electronic control system
4.Power supply system
Consists:
resistant to strong acid pump: 1 set.
It is set up for suction acid fog, the power is 11KW
5.Sedimentation recycling tank
Consists:
1) A emergency collection tank . It is set up for strong acid to import into the tank of high-temperature and strong acid resistance along with polypropylene plastic pipeline in case beaker bursts.
2) Sedimentation storage box. It is set up for recycling gold or other precious metal.
3) Liquid pipeline
Applications:
1. Thick acid mist efficient purification on processes of cleaning jewelry with heated acid and gold dissolving
2. Thick acid mist efficient purification on processes of silver or gold refining.
3. Thick acid mist efficient purification conducted on production of chemical acid.
4. Thick acid mist efficient purification on processes of electroplating and stripping fried color process of metals and plastics;
Purification efficiency: ≥98%. Concentration of instant acid fog during work can be detected by qualified testing organization or company. Exhaust gas at the outlet is in line with discharge requirements in GB16297-1996 "Air Pollutant Discharge Standard" and "Local Standard Atmospheric Emission Limits of Guangdong Province" DB44 / 27-2001.

Comparison on the old and new crafts for the treatment of thick acid smoke generated from 3 acid cleaning cups at a jewelry factory
| Compared projects | Traditional acid smoke purification tower | Concentrated acid fog purifier used indoor |
| Process Equipment | Tower Φ1.5M * 4.5M + fan 7.5KW + 3HP pump + indoor draught hood + indoor pipe + external wall pipeline | Concentrated acid smoke purifier + safe cooking jewelry machine + 1M outlet pipe |
| Purification efficiency | 60%~80% | ≥98% |
| Concentration of acid fog | Low concentration | High concentration |
| Purification method | Neutralized purification at the instant contact moment of gas and liquid two phases | Full bath purification via acid mist passes through absorption liquid |
| Purification time | Contact time between gas and liquid is short, reaction time is also short. | Long contact time, long reaction time. |
| Installation method | Outdoor installation + external walls and pipeline high-altitude installation + swing | Interior + non- external walls pipeline installation + elevator access |
| Power system | 1 fan + 1 water pump | 1 water pump + 0 fan |
| Floor area | Φ1.5M*4.5M+fan(5M2) | L2.0*W0.76*H1.83M (3M2) |
| Mobility | Poor mobility = pipeline disassembly + swing+ large loss | Good mobility = trundle + elevators access + 1M air duct + zero loss |
| Running costs | Electric charge + alkali liquor | Electric charge + alkali liquor |
| Installation schedule | 3-5 days | 0.5 day |
