Description
Technical field
The utility model is related to refined naphthalene rectification and purification and recovery technology field, specifically a kind of refined naphthalene retracting device.
Background technology
Refined naphthalene rectification and purification can obtain higher purity, the more white bright refined naphthalene of appearance, but in refined naphthalene rectification and purification process
In, tradition cooling rely primarily on directly plus 80-90 DEG C or more of hot water cooled down after it is in line go out, but in this case can not
Naphthalene is recycled, and there is also pollutions to environment.It is purified using negative pressure device, need to use that vacuumized by negative pressure will be hot
Amount extraction is gone, but has also taken away partial gas phase naphthalene present in heat during heat is discharged, not environmentally.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of refined naphthalene retracting devices, solve existing refined naphthalene negative pressure essence
Evaporate the problem of refined naphthalene recycles in purification process.
Used technical solution is the utility model to solve above-mentioned technical problem:A kind of refined naphthalene retracting device, including
Receive naphthalene kettle, receive naphthalene kettle on be equipped with vacuum tail gas import, it is described receive naphthalene kettle bottom with receive naphthalene slot be connected to, receipts naphthalene kettle top and
Collection device connects, and receives and is respectively equipped with cooling water inlet, cooling water outlet, steam inlet and steam (vapor) outlet on naphthalene kettle, cooling
Water out and steam inlet are located at the upper end for receiving naphthalene kettle, and cooling water inlet and steam (vapor) outlet are located at the lower end for receiving naphthalene kettle, are located at and receive
The cooling water inlet of the lower end of naphthalene kettle and steam (vapor) outlet share, and are located at the cooling water outlet for receiving naphthalene kettle upper end and steam inlet is total
With.
Receipts naphthalene kettle described in the utility model is 2.
It is equipped with valve between receipts naphthalene kettle described in the utility model and receipts naphthalene slot, receives and is equipped between naphthalene kettle and tail gas collecting device
Valve.
The utility model has the beneficial effects that:The utility model to the vacuum tail gas extracted out in refined naphthalene negative pressure distillation process into
Row processing, recycles the refined naphthalene taken away in vacuum tail gas, not only recycles refined naphthalene and reduces waste, while also avoiding the dirt to environment
Dye, has the following advantages:1, it is recycled by receiving naphthalene kettle, is cooled down vacuum tail gas by cooling water, gas after cooling
Refined naphthalene, which becomes solid, to be existed in receipts naphthalene kettle, when receipts naphthalene kettle fills up, is closed vacuum tail gas import and is simultaneously stopped being passed through cooling water, be passed through
Steam makes solid refined naphthalene liquefy, and flows into and receives the recycling that naphthalene slot realizes refined naphthalene in vacuum tail gas, and the convenient and rate of recovery is higher;2, it receives
Naphthalene kettle is two, is received when one and crystallizes refined naphthalene using another receipts naphthalene kettle when carrying out liquefaction recycling refined naphthalene after naphthalene kettle receives full,
Convenient, process is sustainable, improves working efficiency;3, the recycling of the maximization to refined naphthalene may be implemented in the utility model, avoids
Waste, while reducing the pollution to environment.

Fig. 1 is the utility model overall structure diagram.
It is marked in figure:1, naphthalene kettle is received, 2, cooling water outlet, 3, steam inlet, 4, vacuum tail gas import, 5, receive naphthalene slot, 6,
Cooling water inlet, 7, steam (vapor) outlet, 8, valve, 9, collection device.
Specific implementation mode
As shown, a kind of refined naphthalene retracting device, including naphthalene kettle 1 is received, and vacuum tail gas import 4 is equipped on receiving naphthalene kettle 1, it will
The high heat tail gas that refined naphthalene negative pressure rectification and purification is extracted out in the process, which is passed through, receives naphthalene kettle 1, the bottom for receiving naphthalene kettle 1 and receipts naphthalene slot 5
Naphthalene slot 5 is received in the refined naphthalene deposit of connection, recycling, and the top for receiving naphthalene kettle 1 is connect with collection device 9, recycles remaining tail gas after refined naphthalene
Recycled by collection device 9, avoid being discharged in air to air pollution, receive be respectively equipped on naphthalene kettle 1 cooling water inlet 6,
Cooling water outlet 2, steam inlet 3 and steam (vapor) outlet 7, cooling water outlet 2 and steam inlet 3 are located at the upper end for receiving naphthalene kettle 1, cold
But water inlet 6 and steam (vapor) outlet 7 are located at the lower end for receiving naphthalene kettle 1, go out positioned at the cooling water inlet 6 for the lower end for receiving naphthalene kettle 1 and steam
Mouth 7 shares, and is located at the cooling water outlet 2 for receiving 1 upper end of naphthalene kettle and steam inlet 3 shares, cooling water is first passed through, when refined naphthalene crystalline solid
It fills up after receiving naphthalene kettle 1, stopping is passed through vacuum tail gas and cooling water, is passed through steam, heats liquefied to fixed refined naphthalene and collect.
Further, the receipts naphthalene kettle 1 is 2, when one, which is received naphthalene kettle 1, receives full solid refined naphthalene, using another continue into
Row recycling, makes removal process continue to carry out.
