Abstract
The utility model discloses a hydrogen separation device for biphenyl production tail gas. The hydrogen separation device comprises a hydrogen separation tower, wherein a gas inlet is arranged at the lower end of the hydrogen separation tower, and connected with a tail gas outlet in a biphenyl production device, a remaining gas outlet and a pressure adjusting valve are arranged at the top of the hydrogen separation tower, a one-way valve is arranged at the remaining gas outlet, a hydrogen outlet is arranged on the side wall, a hydrogen separation unit is arranged inside and consists of a cavity, a hermetically connected hydrogen separation diaphragm is arranged at the open end of the cavity, and a gas guide pipe is arranged in the cavity, penetrates through the top of the cavity and the hydrogen outlet and is communicated with the hydrogen inlet in the biphenyl production device. The hydrogen separation device is simple in structure, smart in design and good in sealing property, the utilization ratio of the hydrogen can be greatly improved, the materials can be saved, the production cost is low, and the practicability is strong.
Description
Technical field
The utility model relates to the exhaust gas processing device with crude benzole hydrogenation gas biphenyl processed, relates in particular to the hydrogen separation device in a kind of biphenyl tail gas processed.
Background technology
The mass fraction of biphenyl in coal tar is 0.20%-0.40%, and the overwhelming majority concentrates in washing oil (WOR-1) cut.Biphenyl textile PBBs pbb test content in the crude benzol (RCN) seldom, only account for 0.39% (mass fraction), but it generates more biphenyl in the Litol hydrogenation reaction, so that the biphenyl mass fraction in the discharges material (SC-203) reaches 12.88% at the bottom of the benzene tower tower.After adding hydrogen reaction, there are a lot of tail gas to discharge, in the tail gas of discharging, a large amount of hydrogen is arranged also, therefore to there be a kind of device that the Hydrogen Separation in the tail gas is out supplied the Litol hydrogenation, the hydrogen isolation technics is to utilize membrane separation technique at present, but the design of the hydrogen separation device of prior art is reasonable not, complex structure, the waste material, manufacturing cost is high.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, and the hydrogen separation device in a kind of biphenyl tail gas processed simple in structure is provided.
The utility model is achieved through the following technical solutions:
Hydrogen separation device in a kind of biphenyl tail gas processed, include the Hydrogen Separation tower, described Hydrogen Separation tower lower end is provided with air inlet, tail gas outlet in described air inlet and the biphenyl device processed is connected, the top is provided with residual gas outlet and pressure regulator valve, the residual gas exit is provided with check valve, sidewall is provided with hydrogen outlet, inside is provided with hydrogen separation unit, described hydrogen separation unit comprises that openend is with the cavity of the hydrogen separation membrane sheet that is tightly connected, in the described cavity wireway is arranged, described wireway passes cavity top and hydrogen outlet and is connected with hydrogen inlet in the biphenyl device processed.
Hydrogen separation device in the described biphenyl tail gas processed is characterized in that: all there is the sealing ring sealing junction of described wireway and cavity and Hydrogen Separation tower.
Hydrogen separation device in the described biphenyl tail gas processed is characterized in that: described pressure regulator valve has two, better regulates the air pressure in the Hydrogen Separation tower.
Operation principle of the present utility model is: the tail gas that produces in will biphenyl device processed is arranged in the Hydrogen Separation tower by air inlet, regulate again pressure regulator valve, air pressure in the Hydrogen Separation tower is greater than the air pressure in the cavity, hydrogen is compressed into cavity, entered in the biphenyl device processed by wireway, open check valve, residual gas in the knockout tower is discharged, realize the fully utilization of hydrogen.
The utility model has the advantages that: the utility model is simple in structure, relates to ingeniously, and good airproof performance has improved the utilization rate of hydrogen greatly, saves material, and low cost of manufacture is practical.
