61 far from three-level cryogenic system 5 compression pump 62, the escape pipe 63 that is connected on compression pump 62 and is connect with collecting tank.It is condensed into crossing
A small amount of fixed gas is still had later, and negative tube 61 absorbs fixed gas in VOCs, by restoring original after pressurized treatments
VOCs characteristic collects carry out circulation cleaning again, is discharged again after reaching emission request, and it is untreated good to avoid
VOCs is discharged in atmosphere and pollutes.
As shown in Fig. 2, being to have certain pressure during purified treatment, in whole equipment, when the temperature in equipment
When changing, the damage of integral device can be all caused when pressure is too large or too small.It is deep in diffusion mouth 7 and three-level
Positive pressure safety valve 8 is offered at cooling system 5, and the adjusting work of pressure in equipment may be implemented by positive pressure safety valve 8, avoid
The case where causing equipment to damage due to pressure change difference.
Specific implementation process: collecting box 1 collects VOCs to be treated, when carrying out processing work,
VOCs first passes through dust pelletizing system 2 and is filtered dedusting；Filtered VOCs continues to rise, into cooling system 3 at the beginning of level-one, at the beginning of level-one
The temperature range that cooling system 3 provides is 30 DEG C -35 DEG C, and gaseous state naphthalene, anthracene are compressed, are collected；In VOCs fixed gas after
Continuous to rise and enter second level ICS intercooler system 4, the temperature that second level ICS intercooler system 4 provides collects steam at 0 DEG C；Fixed gas in VOCs
Continue to rise and rise up into automatically three-level cryogenic system 5, the temperature that three-level cryogenic system 5 provides at subzero 20 DEG C, open by benzene hydrocarbon gase
Begin to liquefy, phenols gas starts to liquefy, be collected；A small amount of fixed gas imports in negative pressure collection system 6, carries out pressurized collection,
Realize zero-emission；After completing VOCs processing, to HIGH TEMPERATURE PURGE is carried out in equipment, the attachment of tar in equipment is reduced, improves equipment
Interior cleaning.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
