Abstract
The present invention relates to technical field of waste gas treatment, is specially a kind of VOCs recyclings treatment process.The technical process is：VOCs gases after high-efficiency dust remover dedusting enter in VOCs collectors from bottom, and diesel oil enters from the top of collector and sprays on VOCs gases, and VOCs is after coolant cools down, diesel oil absorbs, and diesel oil VOCs mixed liquors are by exporting recycling.Compared with traditional VOCs absorption techniqueses, treatment process of the present invention recycles VOCs according to the similar principle that mixes of organic compound, it is simple with technical process, the features such as treatment effeciency is high, safe, non-secondary pollution, can be used as fuel, improve economic value after recycling.
Description
Technical field
The invention belongs to technical field of waste gas treatment, and in particular to the VOCs discharged in a kind of chemical industry production process
Recycle technique.
Background technology
VOCs（Volatile organic compounds）That is volatile organic compounds, is generally existing in air
A kind of organic pollution, is mainly derived from the industries such as petrochemical industry, automobile engine tail gas, pharmacy, its main component for hydro carbons,
Phenols, fragrant same clan etc..VOCs can form photochemical fog in an atmosphere, and environment and human body are caused greatly to endanger.VOCs
After entering human body by respiratory tract and skin, the system such as breathing, blood, liver to people and organ cause temporary or permanent
The polycyclic aromatic hydrocarbon such as damage, especially benzene class and the fragrant same clan has carcinogenesis to human body.The excessive emissions of VOCs also to agricultural and
The industries such as herding damage.Therefore the processing of VOCs is increasingly paid attention to be subject to countries in the world, and many countries have promulgated accordingly
Decree, limit the discharge of VOCs.
The main method of domestic processing VOCs has absorption method, membrane separation process, absorption process, Production by Catalytic Combustion Process and condensation method at present
Deng.Although absorption method removal rate is high, since adsorption capacity is limited, it is not suitable for handling high concentration organic gas, when in exhaust gas
When having micelle material or other impurity, adsorbent is vulnerable, while adsorbent needs to regenerate.Membrane separation process have it is energy-efficient,
The characteristics of easy to operate, but invest big, business burden weight, still without practical application.Common WATER-WASHING METHOD removes effect in absorption process
Rate is low, can only remove water miscible organic matter, while can also produce secondary pollution.Burning not only waste of energy is catalyzed, if combustion
Burn insufficient, can also produce new pollutant.Condensation method is simply directly using just significant under high concentration.
The content of the invention
Present invention aims to overcome that prior art defect, there is provided a kind of VOCs recyclings treatment process, the technique
Process is simple, obvious processing effect, cost is low, safe, economic benefit is obvious, non-secondary pollution.
The purpose of the present invention is achieved through the following technical solutions：
A kind of VOCs recyclings treatment process, is specially：VOCs gases after dedusting enter in VOCs collectors from bottom,
Diesel oil enters from the top of collector and sprays on VOCs gases, and VOCs is after coolant cools down, diesel oil absorbs, by exporting back
Receive and recycle
Further, netted condenser pipe is housed in the collector.
Further, the coolant is industrial alcohol.
Further, it is provided with efficient nozzle at the top of the absorption plant.
Further, the diesel oil is ordinary diesel oil or diesel oil, gasoline blending component.
The invention has the advantages that：
Compared with traditional VOCs absorption techniqueses, treatment process of the present invention is according to the similar principle that mixes of organic compound, in diesel oil
Mixed alkanes and other components, can effectively absorb VOCs components, absorb the diesel oil after VOCs and recycled as fuel, this mistake
Journey not only recycles VOCs, reduces secondary pollution, while also increases the additional calorific value of fuel oil, improves burning
Efficiency, produces the economic benefit of bigger.Absorbing liquid selects diesel oil or bavin gasoline mixture, its boiling point and flash-point are higher, compare pure
For gasoline or other one pack systems, safety coefficient is higher, treatment effeciency higher.
Brief description of the drawings
Fig. 1 absorbs treatment process schematic diagram for VOCs of the present invention.
Embodiment
With reference to specific embodiment, the present invention will be further described：
As shown in Figure 1, a kind of VOCs recyclings treatment process, is specially：The VOCs sources of the gas of plant area are filtered by particulate matter
Afterwards, ethanol condensation diesel oil absorption plant is entered from below left side, gaseous matter is dissolved in the bavin of top spray while cooling
In oil, the diesel oil-VOCs mixed liquors after absorption, enter recovery pond from the pipeline of bottom of device.
VOCs waste gas treatment process provided by the invention and processing method, not only eliminate discharge of the VOCs exhaust gas to environment
Pollution, meets cost-effective modern enterprise, raising productivity effect, the requirement of comprehensive utilization of waste materials, suitable under different situations
Hydro carbons, phenols, the volatile organic compounds such as the fragrant same clan absorption processing, possess extensive market application value.
