Abstract
The utility model provides a kind of self-loopa oxidation system, including evaporator, superheater and oxidator, condenser and the reservoir being sequentially communicated, the gas outlet of the reservoir is connected to the evaporator, and the pipeline between the reservoir and the evaporator is equipped with circulating fan.Compared with the existing technology, this system will be filled with the nitrogen of certain pressure by round-robin method in nitrogen in initial reaction stage in system, the nitrogen in system is set to generate internal circulating load with circulating fan, adventitious oxygen is passed through to the entrance of circulating fan again, mix oxygen with the nitrogen of circulation, pure oxygen can be diluted with circulating nitrogen gas in this way, and the nitrogen that can use circulation takes away the heat generated in reaction process, nitrogen recycles not outlet in inside.The exhaust emissions for having prevented oxidative system eliminates pollution, reduces consumption, and solves the problems such as reaction in purity oxygen oxidation reaction is violent, side reaction is more.
Description
Technical field
The utility model belongs to oxidation reaction process equipment applications, more particularly, to a kind of self-loopa oxidation system.
Background technique
It is common oxidation technology with air oxidation process production 4- hydroxyl 2- butanone, this technique has the drawback that: tail
Gas discharge amount is larger；The material taken away is more；Production process is seriously polluted；Supplies consumption is higher.Therefore industrial also to use pure oxygen
Gas oxidizing process produces 4- hydroxyl 2- butanone, i.e., first produces pure oxygen with pressure swing adsorption method, then with 1,3 butanediol of dioxygen oxidation.But
Since oxygen concentration is too high, oxidation process is excessively fierce, causes by-product more for purity oxygen oxidation；The heat generated in oxidation process
Amount cannot shed in time, be also easy to produce hot-spot and generate explosion.
Utility model content
In view of this, the utility model is directed to a kind of self-loopa oxidation system, to solve prior art presence
The problem of.
In order to achieve the above objectives, the technical solution of the utility model is achieved in that
A kind of self-loopa oxidation system, including evaporator, superheater and oxidator, condenser and the storage being sequentially communicated
Liquid bath, the gas outlet of the reservoir are connected to the evaporator, and on the pipeline between the reservoir and the evaporator
Equipped with circulating fan.
Further, it is integral to pass through flanged joint from bottom to top for the evaporator, heater and oxidator.
Further, the gas outlet of the reservoir is connected with the gas distributor of the base of evaporator.
Further, the circulating fan inlet is also connected with independent source nitrogen and source of oxygen respectively.
Compared with the existing technology, self-loopa oxidation system described in the utility model has the advantage that this system
The nitrogen of certain pressure will be filled in system in initial reaction stage by round-robin method in nitrogen, the nitrogen in system is made with circulating fan
Internal circulating load is generated, then adventitious oxygen is passed through to the entrance of circulating fan, oxygen is mixed with the nitrogen of circulation, can use in this way
Circulating nitrogen gas dilutes pure oxygen, and the nitrogen that can use circulation takes away the heat generated in reaction process, and nitrogen is followed in inside
Ring not outlet.The exhaust emissions for having prevented oxidative system eliminates pollution, reduces consumption, and solves purity oxygen oxidation
The problems such as reaction in reaction is violent, side reaction is more.The industrial application of purity oxygen oxidation technology suitable for organic compound.

The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
Embodiment
As shown in Figure 1, a kind of self-loopa oxidation system, including the evaporation being sequentially communicated from bottom to top by flange
Device, superheater and oxidator, wherein oxidator outlet are connected to a condenser inlet, and condensator outlet and a reservoir entrance connect
Logical, the gas outlet of reservoir is connected to further through pipeline with a circulating fan entrance, and the outlet of circulating fan is further through pipeline and institute
The gas distributor for stating base of evaporator is connected.Above-mentioned each equipment connection circularizes, so that self-loopa is presented in whole system
State, the circulating fan inlet is also connected with independent source nitrogen and source of oxygen respectively in addition to this, for supplementing certainly
Oxygen and nitrogen needed for the circulatory system.
Process flow of the above-mentioned self-circulation system for purity oxygen oxidizing process production 4- hydroxyl 2- butanone are as follows: raw material 1,3
Butanediol reaches in oxidator through heat-conducting oil heating in evaporator into superheater after entering vaporization.After nitrogen is mixed with oxidation
Gas enters the gas distributor of base of evaporator after blower, has reacted in oxidator with 1,3 butanediols after superheater
At liquid after cooling enters reservoir, and nitrogen after cooling reenters system circulation through circulating fan and uses.
