Description
Technical field
The present invention relates to pitch exhaust-gas treatment, more particularly to a kind of organic waste gas treatment system of modified coal tar pitch workshop section and
Pitch workshop section.
Background technology
With the development of coking industry, the production capacity of coal tar processing industry just gradually expands, and wanting for carbon product
Seek also more and more higher.In recent years, the mid temperature pitch as carbon product raw material is progressively substituted, being processed further of mid temperature pitch
Become developing direction.At present, mid temperature pitch be processed further have become as the important component part of coal tar processing process, should
Workshop section can produce the modified coal tar pitch product for being widely used in metallurgy, chemical industry, and therefore which is also referred to as modified coal tar pitch workshop section.
The substantially flow process of modified coal tar pitch workshop section is as follows：(1) mid temperature pitch produced by tar distillation is sent in reactor heating furnace and sends out
Raw polymerisation；(2) reacted pitch enters medial launder, and enters gasification cooler recovery heat；(3) liquid bitumen is sent
Enter to pitch height and groove is put, finally enter former and obtain final modified coal tar pitch product.
Due to being solid under pitch normal temperature, in order to become the liquid of convenient transport, the whole process of modified coal tar pitch workshop section
All higher temperature (>200 DEG C) under carry out, such high temperature has led to the generation of a large amount of organic exhaust gas.For example, high in pitch
Put in groove, up to more than 250 DEG C, many organic components in pitch start volatilization to the temperature of pitch, produce a large amount of at groove top
Organic exhaust gas.In addition, at asphalt moulding equipment, hard pitch is contacted generation and acutely vaporizes with water, substantial amounts of organic component
Together with being clipped in, the smog of a large amount of outwards discharges is formed with steam.Monocyclic virtue for these organic exhaust gas, in organic component
Hydrocarbon (as benzene, toluene) only accounts for small part, and which is mainly made up of condensed-nuclei aromatics, such as naphthalene, fluorenes, phenanthrene, anthracene, pyrene, and benzene
And pyrene etc..These condensed-nuclei aromatics belong to heavy tar components, generally in the form of steam or droplet in waste gas, present
The healthy and surrounding enviroment of people can be caused huge harm by the big feature of volatile, easy condensation, toxicity.
At present, the VOCs treatment technology of domestic modified coal tar pitch workshop section still adopts exhaust cleaning technology, to clean oil (such as
Washing oil) organic component in waste gas is removed as absorbent.But, exhaust cleaning technology manifests problems, more next
More it is difficult to meet the needs of environmental protection.Firstly, since the organic exhaust gas temperature of modified coal tar pitch workshop section is higher, cleaning oil is in scrubbing exhaust gas
While, own temperature can also be raised, once temperature is more than 80 DEG C, its own also becomes the emission source of organic exhaust gas；Secondly, wash
Oil belongs to the cut that boiling point is between 230～300 DEG C, therefore to a small amount of light components (as benzene class) in waste gas and a part of heavy
The assimilation effect of component (as benzopyrenes) is all poor so that the tower top of exhaust washing column still gives off substantial amounts of organic waste
Gas.For these problems, manufacturing enterprise employs some corrective measures, such as sets up the cooler of control cleaning oil temperature, and
Increase off-gas condenser etc..But, these measures still thoroughly do not solve the organic exhaust gas emission problem of modified coal tar pitch workshop section.
Although cleaning oil cooler can effective control washing oil temperature, it is to avoid which becomes emission source, and cooler itself can not be improved clearly
Assimilation effect of the washing oil to organic exhaust gas；And off-gas condenser is although can condense out most of heavy tar components,
But condense in the cleaning of the tar on wall to bother very much, need to expend a large amount of manpowers；Furthermore, waste gas is through absorbing, condensation process
Afterwards, some organic components not weighed still are had be not removed, still externally discharges.
