Description
Technical field
The present invention relates to a kind of improvement VOCs systems.
Background technology
The pollution of China VOCs has been subjected to going into politics mansion to the extensive concern of the common people, administers extremely urgent.So far, VOCs
Treatment process can be divided into source reduction technology, process control technology and end treatment technology, and feelings are controlled from domestic existing VOCs
From the point of view of condition, every profession and trade mainly uses end-of-pipe control technology, and control measures are taken to the volatile organic matter generated.Wherein,
In traditional VOCs treatment field comparative maturity, application is relatively extensive for absorption, absorption, condensation, combustion technology；UF membrane,
Biotechnology, plasma technology are then emerging technologies, are also obtaining extensive concern in the recent period.But these technologies reported or used
It mainly considers a problem from point, i.e., is only dedicated to reductions of total VOCs to air discharge capacity（That is emission reduction）, can usually bring it
The increase etc. of his new problem, such as secondary pollution, safety in utilization and enterprise's total energy consumption, few technologies are from generation VOCs's
The industry actual production overall situation is set out, and is systematically carried out VOCs improvement, energy saving, emission reduction and safety issue are once solved.
The application number 200810185561.8 of first Chinese patent, a kind of entitled environment friendly energy-saving air-discharging treating device and side
Method；The application number 200920152633.9 of second Chinese patent, a kind of entitled energy conservation and environmental protection organic solvent voc treatment device；
The application number 201610742937.5 of third Chinese patent, a kind of entitled energy-saving organic waste gas treatment system；4th China
The application number 201610833165.6 of patent, a kind of entitled energy-efficient formula spraying drying system；The Shen of 5th Chinese patent
Please numbers 201710787572.2, a kind of entitled combustion-type VOC processing units;With the application number of the 6th Chinese patent
201711329846.X the entitled energy saving hybrid processing system of Industrial Stoves VOC exhaust gas；It has all referred to not only energy saving but also emission reduction
VOCs treatment technologies, common point are directly to carry out burning processing after concentrating VOCs, generated treated qualified air-flow
Discharging directly into atmosphere, generated thermal energy are utilized by heat exchange, are reduced enterprise and are produced total energy consumption.
But it is this by heat exchange realization heat energy utilization, necessarily there is certain heat loss；The directly method of burning processing
The VOCs for comparing high concentration is needed, is easier that safety problem occurs, for example explode；Discharging directly into atmosphere after VOCs burnings, works as equipment
When fluctuation of service, discharge beyond standards are easy, the stability of regulation effect is poor.
The application number 201710839338.X of 7th Chinese patent, entitled energy saving VOC exhaust treatment systems；Relatively preceding institute
For stating patent, the energy-saving and emission-reduction that not only have its common, it is also contemplated that it is total will to account for VOCs exhaust gas for the self-contained thermal energy of exhaust gas
For drying in the VOCs exhaust gas recirculations to the drying cavity body of amount 20% to 40%.
The application number 201710097254.3 of 8th Chinese patent, it is entitled for handling VOC gas method for pyrolysis, relatively
The advance of 7th Chinese patent is the high usage of waste gas stream thermal energy：VOCs air-flows collected by from production equipment exist
After the processing of 700 to 800 degree, gained cleans thermal current 100% and returns production equipment by pipeline, greatly improves the profit of thermal energy
With rate, reduce the total energy consumption of actual production.Although the technology and taking improvement to arrange the volatile organic matter generated
Apply, but high temperature remove VOCs cleaning thermal current not according to the such direct emission air of other technologies, but by temperature adjustment after
Input needs the production equipment of hot wind directly to replace the ambient wind for needing electric energy or steam that can heat originally, and carries new generate
VOCs enter next cycle, achieved the purpose that it is a kind of not only having handled VOCs and reduce produce total energy consumption；In the technology
It burns without the concentration also flames of anger, is that the VOCs that will be collected into directly is pyrolyzed in high temperature furnace, safety has obtained certain
It improves.But its cleaning gas tream does not lead to air, but forms airflow circulating, persistently have at production equipment a small amount of fresh air into
Enter, pressure can gradually increase, and entire gas channel has the security risk of explosion；And the technology is only referred to VOCs airflow circulatings
There is a certain distance part there is no produce reality is considered comprehensively from system treatment technology.
