Under the monitoring of PLC control system：

Under the action of main air blower, exhaust gas enters water scrubber by the first air inlet, and big particle and portion are dissolved in Water enters through pipeline and the second air inlet from the first gas outlet remove fog chamber later, removes what exhaust gas was brought into because flowing through water scrubber Then moisture enters activated carbon adsorption through pipeline and absorption air inlet from the second gas outlet and case is desorbed, most afterwards through absorbing gas port Outer row, using this exhaust treatment system, to the high treating effect of organic exhaust gas, the treatment effeciency of organic exhaust gas is more than 95%, energy Enough ensure organic exhaust gas qualified discharge；

Since main air blower is frequency conversion fan, i.e., main air blower is by frequency converter start and stop, and the entrance of main air blower installs third wind Pressure sensor, third wind pressure sensor output signals to PLC control system and to frequency converters, and frequency converter is in PLC control system Frequency conversion interval range carry out frequency control main air blower motor speed, when main air blower entrance wind pressure becomes larger, frequency converter is automatic Change frequency and control the faster rotational speed of main air blower motor, when wind pressure reduces at fan inlet, frequency converter changes frequency automatically Rate simultaneously controls the reduction of main air blower motor speed, and the traffic coverage of frequency converter frequency is arranged to ensure wind turbine simultaneously in PLC control system Ordinary life；

During this, when exhaust gas enters water scrubber, tap water is under the action of water pump through spray assemblies and the first water inlet It is sprayed downwards from the upper end of water scrubber, from below to up by gas-liquid mixed layer, impurity and portion gas in exhaust gas are dissolved in exhaust gas Water, treated, and exhaust gas is discharged into from the first gas outlet except fog chamber；Water under spraying simultaneously goes out from the first of the lower end of water scrubber The mouth of a river is discharged；

From water scrubber come out exhaust gas from the second air inlet enter remove fog chamber, then from the inside between two layers of demisting layer into Gas face, by polyhedron empty ball layer demisting filter, by the harmful substance being mingled in the moisture and moisture in polyhedron empty ball layer from Second water outlet is discharged, and using outside outlet face, is discharged by the second gas outlet, and case is desorbed into activated carbon adsorption, passes through Aforesaid way increases the contact area of demisting layer and exhaust gas, can effectively filter fog therein, promotes demisting efficiency；

Enter activated carbon adsorption from absorption air inlet from the exhaust gas come out except fog chamber and case is desorbed, through in activated carbon adsorption exhaust gas Harmful substance after from absorption gas outlet through first exhaust pipeline discharge, carry out at this time is activated carbon adsorption desorption case absorption Process in adsorption process, is desorbed import and desorption all closes, in use for some time, be desorbed, the process In, import and desorption is desorbed and all opens, absorption intake interface and absorption gas outlet are closed, high-temperature steam from desorption import into In cartonning body, desorption process is carried out, the gas-liquid after desorption enters condenser, after condensation separation, gas part qualified discharge, liquid Body portion is due to being waste liquid, centralized recovery processing；Separately after steam is desorbed, due to what can be brought into containing steam in activated carbon Steam, therefore activated carbon is dried with dry wind, extend the service life of activated carbon；

During this system is run, except fog chamber is equipped with the first wind pressure sensor, for detecting the wind pressure except fog chamber, and will Real-time data transmission reminds staff to check in time to PLC controller when pressure difference is more than setting value, replaces except fog chamber Demisting layer etc.；

Activated carbon adsorption is desorbed case and is equipped with the second wind pressure sensor, for detecting the wind pressure except fog chamber, and data are real-time It is transferred to PLC controller, when pressure difference is more than setting value, staff is reminded to check in time, replaces activated carbon etc., timely processing Failure ensures the normal work of equipment；And also there is temperature sensor, also can by temperature parameter real-time Transmission to PLC controller, It is further ensured that the normal operation of equipment.

The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every Equivalent structure made based on the specification and figures of the utility model is applied directly or indirectly in other relevant technologies Field is equally included in the patent within the scope of the utility model.
