Above-mentioned plating waste gas is Zero discharging system in a organized way, also comprises a set of pre-treatment exhaust treatment system being connected with exhaust outlet 9 in pre-treatment exhaust gas centralized; Described pre-treatment exhaust treatment system comprises the 3rd exhaust gas treating tower 11 being connected with exhaust outlet 9 in pre-treatment exhaust gas centralized via exhaust gas recycling tube road 10, described the 3rd exhaust gas treating tower 11 is communicated to the 4th exhaust gas treating tower 13 by the second blower fan 12, and described the 4th exhaust gas treating tower 13 is communicated to pre-treatment circulating air by the second dehumidifier 14 and concentrates air inlet 15.
The utility model is electroplated waste gas Zero discharging system in a organized way, the high altitude discharge tower of existing electroplating processes system is cancelled, the substitute is a set of waste gas purification apparatus, this waste gas circulation purifier is processed the waste gas purification of generation to be recycled in original treatment facility and is re-used, make to electroplate waste gas and realize zero-emission, fully realized the requirement of environmental protection.
Accompanying drawing explanation
Fig. 1: the utility model is electroplated waste gas Zero discharging system structural representation in a organized way.
The specific embodiment
Referring to accompanying drawing, provide the specific embodiment of the present utility model, be used for formation of the present utility model to be further described.
Embodiment 1
The plating waste gas of the present embodiment in a organized way Zero discharging system with reference to figure 1, electroplate waste gas Zero discharging system in a organized way, comprise the chromium mist treatment system that a set of chromium mist exhaust outlet 1 with electroplating notch is connected, described chromium mist treatment system comprises that the chromium mist being connected with the chromium mist exhaust outlet 1 of electroplating notch via chromium mist reclaim line 2 purifies recover 3, described chromium mist purifies recover 3 and is communicated with the first exhaust gas treating tower 4, described the first exhaust gas treating tower 4 is communicated with the second exhaust gas treating tower 6 via the first blower fan 5, described the second exhaust gas treating tower 6 is connected with the first dehumidifier 7 by pipeline, described the first dehumidifier 7 final by pipeline connection to the air inlet 8 of electroplating notch,
Above-mentioned plating waste gas is Zero discharging system in a organized way, also comprises a set of pre-treatment exhaust treatment system being connected with exhaust outlet 9 in pre-treatment exhaust gas centralized; Described pre-treatment exhaust treatment system comprises the 3rd exhaust gas treating tower 11 being connected with exhaust outlet 9 in pre-treatment exhaust gas centralized via exhaust gas recycling tube road 10, described the 3rd exhaust gas treating tower 11 is communicated to the 4th exhaust gas treating tower 13 by the second blower fan 12, and described the 4th exhaust gas treating tower 13 is communicated to pre-treatment circulating air by the second dehumidifier 14 and concentrates air inlet 15.
The plating waste gas of the present embodiment is Zero discharging system in a organized way, and it is all existing known equipment in prior art that the chromium mist adopting in described chromium mist treatment system and pre-treatment exhaust treatment system purifies recover 3, the first exhaust gas treating tower 4, the second exhaust gas treating tower 6, the first dehumidifier 7, the 3rd exhaust gas treating tower 11, the 4th exhaust gas treating tower 13 and the second dehumidifier 14.The utility model combines the said equipment is organized, original waste gas discharging by high altitude discharge tower is reached rationally and effectively utilize, and its air cleaning rate approaches 100%, and without discharge, pollution-free.
