Hole is conducive to improve naphthalene treatment effeciency there is no leakage problem.
Further, sealing rubber ring is provided in the screwed joint.Pass through setting sealing rubber ring, it is ensured that connection it is close
Feng Xing prevents the leakage of distillation naphthalene.
Further, the bolt of the screwed joint is Elastic Bolts.The distillation naphthalene temperature that rotary drum crystallizer is discharged is higher,
It can reduce influence of the temperature to bolt strength by the way that Elastic Bolts are arranged, distillation naphthalene leakage can be prevented.
Further, the pulsed jet cloth filter quantity is 2-6 group.By the way that multiple groups pulsed jet cloth filter, pulse is arranged
Bag filter can be used cooperatively, and improve the treatment effeciency of naphthalene.
Further, inert gas is passed through into pulsed jet cloth filter, the high temperature inert gas is nitrogen, zero group gas
One or more of.By being passed through inert gas, pulsed jet cloth filter is by pulse inert gas the naphthalene above cloth bag
Under vibration, it can prevent from exploding, greatly reduce security risk.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1. Explosion-proof cap can tightly cover explosionproof hole by setting Explosion-proof cap, there is no leakage problem, be conducive to improve naphthalene
Treatment effeciency；
2. crude naphthalene collected by is entirely finished product, can increase the income of enterprise with direct marketing；
3. can under pulsed jet cloth filter leans on pulse inert gas that the naphthalene above cloth bag is shaken by being passed through inert gas
To prevent from exploding, security risk is greatly reduced；
4. being filtered, being had to gas containing naphthalene using the filtration of fabric by setting pulsed jet cloth filter
Conducive to the protection of environment；
5. pulsed jet cloth filter can be used cooperatively by setting multiple groups pulsed jet cloth filter, the processing of naphthalene is improved
Efficiency；
6. by setting screwed joint, convenient for the installation and maintenance of connecting tube；
7. bag filter can be prevented because superpressure phenomenon occurs in operating reason, ensure that operation by setting explosionproof hole
The safety of process；
8. passing through setting sealing rubber ring, it is ensured that the leakproofness of connection prevents the leakage of distillation naphthalene；
9. can reduce influence of the temperature to bolt strength by the way that Elastic Bolts are arranged, distillation naphthalene leakage can be prevented.
