Description

Platinum catalyst tail liquid treatment device produced in the recovery and purification process

technical field

The utility model relates to the technical field of catalyst tail liquid treatment, in particular to a treatment device for platinum catalyst tail liquid produced in recovery and purification processes.

Background technique

The tail liquid of the platinum catalyst has a high viscosity, and the traditional tail liquid treatment equipment and process slag have a high water content, and the follow-up treatment will cause great environmental pollution and cannot meet the national standard. The traditional process is: clarification storage tank (slag liquid with water content ≥ 40%)-------steel tray-------push plate furnace incineration----waste gas treatment system . The feed liquid corrodes the feed pan quickly, the push plate furnace has low processing efficiency, large pollution, and the processing is not thorough and the effect is poor.

Therefore, a new equipment and a new process flow are needed to treat the viscous catalyst tail liquid to reduce environmental pollution and improve efficiency and effect.

Utility model content

The technical problem to be solved by the utility model is that the existing treatment equipment for catalyst tail liquid with high viscosity has heavy pollution, low efficiency and poor effect.

The platinum catalyst tail liquid treatment device produced in the recovery and purification process of the utility model uses a self-stirring sludge pump to stir the catalyst tail liquid with a high viscosity, and then processes it through a decanter centrifuge to reduce the water content. Finally, it enters the incinerator for incineration treatment. The material tray is set as a lifting tray, which is convenient for feeding and can maximize the efficiency of the incineration rate. The entire equipment has a reasonable structure, high efficiency, good treatment effect, and reduces pollution.

Further, a waste gas treatment device is also included, and the waste gas treatment device is connected to the exhaust outlet of the incinerator. The exhaust gas produced by the incinerator is purified to further reduce the pollution.

The preferred technical solution is that the clarification storage tank, the self-stirring sludge pump, the decanter centrifuge and the incinerator are all connected by an auger for material transfer. Due to the high viscosity of the tail liquid, the material transfer of the tail liquid is realized by a powered auger, which can improve the efficiency. At the same time, it is equivalent to pre-stirring the tail liquid during the transfer process, killing two birds with one stone.

A further improvement is that the tray is set in a circular shape, the center of which is rotatably connected to the rotating shaft, the entire tray is evenly divided into multiple areas, the rotating shaft is rotatably connected to the middle position of the top of the incinerator, and a feed inlet is provided on the top of the incinerator , the outlet of the auger connected with the decanter centrifuge is connected to the feed inlet, and each divided area of the tray can be rotated under the feed inlet. The material tray can be made of steel, and the surface of the tray is partitioned, which can increase the contact surface of the incineration and improve the efficiency, and the feeding of the tray is convenient and fast. , After one area is fed, turn the tray to feed the next area. After the feed is completed, lower the tray to a suitable area in the incinerator for incineration, so as to avoid material splashing during feeding and falling into the bottom of the incinerator. It is difficult to clean, and the position of the tray in the incinerator can be adjusted according to the incineration temperature required by the material, with high efficiency, energy saving and environmental protection.

The platinum catalyst tail liquid treatment device produced in the recovery and purification process of the utility model has high equipment efficiency, energy saving and environmental protection, and the treatment process is also more efficient and environmentally friendly. After being stirred by the self-stirring sludge pump and treated by the decanter centrifuge, the water content of the slag liquid can be reduced to about 10%, and then it is incinerated in the incinerator. The waste gas generated by the incinerator is also treated by the waste gas treatment system and then discharged into the atmosphere. The platinum catalyst tail liquid treatment device produced in the recovery and purification process of the utility model is first stirred by a self-stirring sludge pump and then processed by a decanter centrifuge. A good foundation has been laid, so that the incinerator has high incineration efficiency, less slag loss, long service life of the material tray, and greatly reduces environmental pollution. The structure design of the incinerator is reasonable, which can improve efficiency and prolong the service life of the equipment.
