Background technology
Backwash process is one of key technology of catalytic slurry filtration system, it is necessary to by the solid of slurry oil filter system
Filter cake is backwashed, and carries out deslagging.Slurry oil filtration system recoil washing oil requirement tried one's best with slurry oil feeding temperature it is close, and
And flow must at any time be adjusted according to being actually needed for system.
Existing slurry oil filtering, recoil washing oil is directly entered slurry oil filtration system by pipeline mode and backwashed；
Due to backwash process be intermittently operated, the intermittent time not fix, it is necessary to recoil washing oil changes in flow rate it is very big.Also, with reference to
Device actual production is run, and the oil temperature for the washing oil that recoils is there is also fluctuation, in addition, intermittently operated also results in recoil washing oil oil temperature
Continuous decrease.
Therefore, according to actual design and production operation, it is found that this technique has the following disadvantages：
1) existing technical flow design, it is impossible to the flexibly requirement of reply recoil washing oil flowed fluctuation change, can not be fitted
The state of the washing oil intermittent operation that should recoil operation.There is recoil washing oil flow in actual production excessive and waste auxiliary material,
Or underfed, efficiently system can not be backwashed in time.
2) existing process can not control recoil washing oil well into the temperature of system.The reduction of backwash oil temperature can be led
The reduction of clarified oil flow after filter is caused, filter effect is influenceed.
The content of the invention
The technical problems to be solved in the utility model be to provide a kind of recoil washing oil can stable supplying, oil temperature supplying is stable,
Recoil washing oil and the stable feed system of recoil washing oil in the close slurry oil filter process of slurry oil feeding temperature.
Technical solution of the present utility model is：
A kind of stable feed system of recoil washing oil in slurry oil filter process, including slurry oil filtration system, its special character
It is：The backwash oil-in of slurry oil filtration system is connected with circulating tank by pipeline, slurry oil filtration system and circulating tank it
Between pipeline provided with backwash oil circulating pump, the circulating tank by pipeline, backwash oil circulating pump be connected with cycle heat exchange
Device is simultaneously connected with the tube side of circulation heat exchanger, and the tube side outlet of the circulation heat exchanger is connected by pipeline with circulating tank；
Flow control valve is provided with the pipeline of circulation heat exchanger in backwash oil circulating pump and circulation heat exchanger；The slurry oil filtering
The clarification oil export of system is connected by pipeline with the shell side of circulation heat exchanger, and the shell-side outlet of the circulation heat exchanger passes through
Pipeline is connected with clarification oil tank.
The beneficial effects of the utility model are：
It is simple in construction, low operation cost.Circulation heat exchanger, recoil washing oil circulating tank are set up, is that slurry oil filtration system is carried
Fed for stable backwash.Recoil washing oil enters circulating tank, and material outlet utilizes stream by backwashing oil circulating pump pressure-raising
Clarified oil is exchanged heat after adjustable valve control flow, with filter, and the recoil washing oil after heat exchange is back to circulating tank again, reaches and constantly follows
Ring exchanges heat.Draw simultaneously on the circular route of recoil washing oil and branch to slurry oil filtration system, be embodied as slurry oil filtration system and carry out instead
Rinse.The system can not only maintain the temperature of slurry oil filtration system recoil washing oil invariable, make its constantly close to filtering system
The temperature of system, it is ensured that the feed rate of recoil washing oil changes as the demand of slurry oil filtration system is supporting at any time.
