Description
Technical field
The utility model is related to the production technical field of industrial methanol sodium, specifically a kind of alkaline process produces the production of sodium methoxide
Device.
Background technology
Producing sodium methoxide mainly has two methods of sodium method and alkaline process at present：
It is simple for process one is sodium method, high conversion rate, but have prodigious danger.
Another kind is alkaline process, and technique conversion ratio is low, while needing constantly to remove the water that reaction generates, and energy consumption is higher,
But technique is relatively safe.
To reduce the production cost of alkaline process sodium methoxide device, reducing the unit consumption of the synergic systems such as steam, recirculated water becomes head
Want problem.The capital equipment of alkaline process sodium methoxide process units is reaction tower, rectifying column, since alkali process has strong invertibity,
Therefore the water generated in reaction process must be removed in time, since reaction pressure tower is high（60KPa）, the gas of reaction column overhead generation
Phase（Main component is methanol, water）Rectifying column can be entered by pressure difference（Rectification column pressure 40KPa）, rectifying column tower top obtains aqueous
Extremely low methanol is measured, is pressurized through pump after being condensed by condenser, partly as meeting rectifier column reflux, evaporator is sent into part（It steams
Vapour heats）Become methanol steam and enters reaction tower.In the above operating process, since Rectification column pressure is less than reaction tower,
Rectifying tower top gaseous phase needs first to be condensate in vaporization and be pressurized that reaction tower could be entered, this process is needed to consume a large amount of steam and be followed
Ring water causes alkaline process sodium methoxide plant energy consumption higher.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of alkaline process and produces sodium methoxide
Process units.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution：
A kind of alkaline process produces the process units of sodium methoxide, including raw material storage tank and reaction tower, the connection of reaction tower top exit
Rectifier bottoms entrance, rectifying column top exit are divided into three tunnels：The first via connects the hot side entrance of feed preheater, raw material preheating
The hot side outlet of device connects return tank；Second tunnel connects the hot side entrance of condenser, and the hot side outlet of condenser connects return tank,
Return tank outlet at bottom connects reflux pump, and reflux pump connects one side entrance of top of rectifying column；Third road connects liquid knockout drum,
The output end connect compressor of liquid knockout drum, compressor connect one side entrance of reaction tower lower part.
The raw material storage tank pumps the cold side input port of connection feed preheater by raw material, and the cold side outlet port of feed preheater connects
Connect the feed(raw material)inlet of reaction tower top side.
The compressor setting variable frequency adjustment and reflux line, compressor frequency and reflux are adjusted by gas phase pipeline pressure
Pipeline control valve opening maintains compressor delivery pressure to stablize.
The purpose of this utility model is to provide the corrective measure of traditional soda sodium methoxide device, the gas of methanol rectification column overhead
Mutually part enters condenser and recirculated water heat exchange is condensed into methanol, partly enters heat exchanger and is condensed into the heat exchange of raw alcohol sodium solution
Methanol, the methanol liquid of this two parts condensation is pressurized through pump returns to rectifying column, and rectifying column operation is adjusted as reflux.Rectifying tower
Push up remaining gas-phase methanol through liquid separation tank detach liquid, subsequently into compressor boost to 65Kpa, methanol vapor phase after supercharged into
Enter reaction tower lower part.
The advantageous effect that the utility model is reached is：
1, the utility model can effectively reduce steam consumption, and compared with traditional handicraft, liquid methanol sodium per ton can be reduced
2.4t steam.
2, the utility model can effectively reduce cycle water consumption, offset with traditional handicraft, and liquid methanol sodium per ton can be reduced
256m³/h（Δt=5℃）Recirculated water internal circulating load.
