Deposit, by pumping the washings in tank located underground are delivered to methanol distillation column being recycled for interruption.In this flow
During, since ground tank is normal pressure tank, unavoidable phenomena such as producing part smell, and be interrupted recycling and dynamic equipment is used
Excessively frequently, equipment attrition failure or accident are be easy to cause.The washings of interruption conveying can not be to the extraction in methanol distillation column
Water carries out continuing replacement, causes extraction water to show weak acid corrosion methanol distillation column in During Process of Long-term Operation.Methanol returns now at the same time
The drainpipe for receiving tower is directly discharged to oily wastewater well, since the extraction coolant-temperature gage of methanol distillation column bottom of towe is up to 105 DEG C, can lead
Cause the rise of oil-containing well temperature, it is possible to create phenomena such as fuel gas, there is hidden danger.
The content of the invention
The purpose of this utility model is that there are the above problem for existing technology, it is proposed that the first in a kind of MTBE devices
Alcohol extraction and recovery utilizes structure, and the technical problem that the utility model solves is security risk when reducing methanol extraction recycling.
The purpose of this utility model can be realized by following technical proposal：
A kind of methanol extraction in MTBE devices recycles structure, and MTBE devices include settling tank, it is characterised in that first
Alcohol extraction and recovery includes pressurized tank, methanol distillation column, recirculated water cooler and greasy dirt supply mains using structure, and the settling tank passes through
Pipeline one is connected with the water inlet of pressurized tank, and the water outlet of the pressurized tank is connected by pipeline two with methanol distillation column, described
Drainpipe in methanol distillation column is connected by pipeline three with recirculated water cooler, and the water recirculator connects with greasy dirt supply mains
It is logical.
The washings containing a certain amount of methanol that settling tank produces enter pressurized tank by pipeline one, by pressurized tank
Washings are delivered to methanol distillation column by the effect of air pressure by pipeline two, since pressurized tank can be constant by adjusting pressure
Conveying washings, therefore can guarantee that washings it is continual and steady be transported to methanol distillation column, by washings persistently to first
Acidic water in alcohol recovery tower alleviates equipment sour corrosion, and since pressurized tank has pressure, will not cause into line replacement
The volatilization of methanol, avoids the waste of methanol；The extraction water of methanol distillation column high temperature enters recirculated water cooler by pipeline three
Cooled down so that 105 DEG C of extraction water is cooled to 45 DEG C or so, it is cooled after extraction water be discharged to greasy dirt supply mains,
Eventually enter into sewage plant to be handled, avoid the security risk of production, while ensure that the environmental protection of discharge；Wherein pressurized tank,
Recirculated water cooler is the existing product that can be bought on the market, and settling tank and methanol distillation column are the group in existing MTBE devices
Part.
Methanol extraction in above-mentioned MTBE devices is recycled in structure, and the stage casing of the pipeline two has buffering
Section, the diameter of the breeze way are more than the diameter of the pipeline two positioned at breeze way both ends, air bleeding valve are fixed with the breeze way.
Breeze way can alleviate the flow velocity of washings in pipeline two so that it is gentler that washings enter methanol distillation column.
Methanol extraction in above-mentioned MTBE devices is recycled in structure, fixed between the pipeline two and pressurized tank
There is flow control valve.By flow control valve in production by the flow control of washings in 400~900kg/h.
Methanol extraction in above-mentioned MTBE devices is recycled in structure, is fixed with the periphery of the pipeline three scattered
Backing.Followed by heat sink heat dissipation Temperature fall, the water cooler cooling of energy auxiliary circulation, the pressure of reduction recirculated water cooler, reduction
The power of ring water cooler, has saved cost.
Methanol extraction in above-mentioned MTBE devices is recycled in structure, and the stage casing of the pipeline one is communicated with fluid infusion
Pipeline, the end of the replenishing line are communicated with sealant supplement cylinder.Washings without methanol are housed in sealant supplement cylinder, are reduced in settling tank
Washings are supplemented by sealant supplement cylinder during output washings, ensure continual conveying washings.
Compared with prior art, the methanol extraction in this MTBE devices, which recycles structure, has reduction methanol extraction recycling
When security risk the advantages of.
