Description
Technical field
The present invention relates to printing and dyeing exhaust gas field more particularly to a kind of printing and dyeing waste gas treatment process.
Background technique
Printing and dyeing workshop needs to dye yarn, and many exhaust gas, especially forming machine can be generated in dyeing course and is generated
Exhaust gas, and dye in the device of the waste water of discharge during processing and also have exhaust gas, must need to handle exhaust gas,
The working environment of exhaust gases people, damages human body, and pollutes environment.At present for the place for exhaust gas of printing and dyeing in production
Science and engineering skill cannot thoroughly be handled exhaust gas, still can cause environmental pollution.Therefore solve the problems, such as that this just seems ten
Divide necessity.
Summary of the invention
To solve the above problems, the present invention provides a kind of printing and dyeing waste gas treatment process, first by the exhaust gas of printing and dyeing workshop and
The exhaust gas of the processing unit of dyeing waste water focuses in waste heat box, is carried out at cooling to the exhaust gas of waste heat box using heat exchanger later
Reason, exhaust gas uses second level glass fiber filter device to be filtered out large particle after first using filter screen filtration later, then gives up
Gas passes through high energy C-band first in photooxidation exhaust device, then passes through O3Catalysis oxidation, activated carbon adsorption device is inhaled later
It is attached, finally burned using high-temperature plasma device, it is final to discharge, exhaust gas detect whether before discharge it is up to standard, in this way
It can be very good thoroughly to be removed pollution to exhaust gas, guarantee that the working environment of workers is not contaminated, solve in background technique
The problem.
The object of the present invention is to provide a kind of printing and dyeing waste gas treatment process, include following steps:
Step 1: the exhaust gas that air exhauster extracts dyeing workshop focuses in waste heat box；
Step 2: the exhaust gas that air exhauster extracts the processing unit of dyeing waste water focuses in waste heat box；
Step 3: room temperature is cooled down to the exhaust gas in waste heat box；
Step 4: the exhaust gas in waste heat box is filtered out into large particle, in filtered exhaust extraction to photooxidation exhaust device；
Step 5: exhaust gas first carries out brokenly macromolecule polluter in exhaust gas by high energy C-band in photooxidation exhaust device
Bad cracking；
Step 6: exhaust gas passes through O in photooxidation exhaust device3Catalysis oxidation kills bacterium；
Step 7: exhaust gas is subjected to adsorption treatment by activated carbon adsorption device；
Step 8: exhaust gas is subjected to waste gas from incinerator by high-temperature plasma device；
Step 9: exhaust gas is finally discharged into atmosphere.
Further improvement lies in that: the step 3 cools to be handled using heat exchanger, and heat is recyclable to be recycled.
Further improvement lies in that: extract exhaust gas before step 9 exhaust gas discharge and test, see whether qualified discharge,
If not up to standard, exhaust gas turns again to step 5 and is handled.
Further improvement lies in that: the step 4 filtering large particle uses second level glass after using filter screen filtration first
Fine filter device is filtered.
Beneficial effects of the present invention: the present invention is first by the exhaust gas of the processing unit of the exhaust gas of printing and dyeing workshop and dyeing waste water
It focuses in waste heat box, cooling processing is carried out using heat exchanger to the exhaust gas of waste heat box later, exhaust gas first uses filter screen later
Large particle is filtered out using second level glass fiber filter device after filtering, then exhaust gas is logical first in photooxidation exhaust device
High energy C-band is crossed, then passes through O3Catalysis oxidation, activated carbon adsorption device is adsorbed later, is finally filled using high-temperature plasma
Set and burned, it is final to discharge, exhaust gas detect whether before discharge it is up to standard, can be very good so thoroughly to exhaust gas into
Row removes depollution, guarantees that the working environment of workers is not contaminated, suitable for production.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention will be described in further detail with reference to the examples below, the embodiment
For explaining only the invention, it is not intended to limit the scope of the present invention..
The present embodiment provides a kind of printing and dyeing waste gas treatment process, include following steps:
Step 1: the exhaust gas that air exhauster extracts dyeing workshop focuses in waste heat box；
Step 2: the exhaust gas that air exhauster extracts the processing unit of dyeing waste water focuses in waste heat box；
Step 3: room temperature is cooled down to the exhaust gas in waste heat box；
Step 4: the exhaust gas in waste heat box is filtered out into large particle, in filtered exhaust extraction to photooxidation exhaust device；
Step 5: exhaust gas first carries out brokenly macromolecule polluter in exhaust gas by high energy C-band in photooxidation exhaust device
Bad cracking；
Step 6: exhaust gas passes through O in photooxidation exhaust device3Catalysis oxidation kills bacterium；
Step 7: exhaust gas is subjected to adsorption treatment by activated carbon adsorption device；
Step 8: exhaust gas is subjected to waste gas from incinerator by high-temperature plasma device；
Step 9: exhaust gas is finally discharged into atmosphere.
The step 3 cools to be handled using heat exchanger, and heat is recyclable to be recycled.The step 9 exhaust gas
Discharge before extract exhaust gas test, see whether qualified discharge, if not up to standard, exhaust gas is turned again at step 5
Reason.The step 4 filtering large particle uses second level glass fiber filter device to be filtered after using filter screen filtration first.
The exhaust gas of the processing unit of the exhaust gas of printing and dyeing workshop and dyeing waste water is focused in waste heat box first, later to useless
The exhaust gas of gas tank carries out cooling processing using heat exchanger, and exhaust gas uses second level glass fiber filter after first using filter screen filtration later
Device is filtered out large particle, and then exhaust gas passes through high energy C-band first in photooxidation exhaust device, then passes through O3Catalysis
Oxidation, activated carbon adsorption device is adsorbed later, is finally burned using high-temperature plasma device, final to discharge, discharge
It is preceding exhaust gas detect whether up to standard, it can be very good thoroughly to be removed pollution to exhaust gas in this way, guarantee worker's work
Environment is not contaminated, suitable for production.
