Background technique
Ethylene oxide cooperation ethylene oxide transfer pump in tank car is all transported in basin with nitrogen pressurization unloading in operation by current ethylene oxide, the requisite drain tank that will arrange is with pressure release, ensure the feasibility of mass transport, ethylene oxide gas emptying is on the one hand to environment, on the other hand also can the material of large losses, and start extremely inconvenient at discharging initial stage and later stage ethylene oxide transfer pump, first pressure discharge operations will be carried out, and need a large amount of nitrogen owing to driving mass transport and later stage to purge, cost certainly will be increased, also easy foreign gas to be incorporated in ethylene oxide further, downstream product quality is easily caused to go wrong.
Model utility content
Technical problem to be solved in the utility model is to provide one does not need evacuating device, does not need additional nitrogen to drive, the closed loop oxidative ethane unloading unit of energy-conserving and environment-protective.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of ethylene oxide closes unloading unit, it is characterized in that: comprise balance tube, anti-explosion gas suction booster and transfer pump, described anti-explosion gas suction booster is connected with ethylene oxide storage tank and tank car respectively through balance tube; Described transfer pump is connected with ethylene oxide storage tank and tank car respectively,
Further technological scheme is, also comprise explosion-proof manual modulation valve, described explosion-proof manual modulation valve is located between anti-explosion gas suction booster and ethylene oxide storage tank, described explosion-proof manual modulation valve is located between anti-explosion gas suction booster and tank car, described explosion-proof manual modulation valve is located between transfer pump and ethylene oxide storage tank, and described explosion-proof manual modulation valve is located between tank car.
Further technological scheme is, anti-explosion gas increases pump to be needed to arrange earthed system, and safety grounding.
Further technological scheme is also, all pipeline connection places are provided with pad, and described pad is teflon material.
The beneficial effect adopting technique scheme to produce is: the utility model does not need outlet pressure release before ethylene oxide transfer pump is opened, do not need turn on pump in advance, idle running, extend ethylene oxide transfer pump working life, avoid the waste of material and the pollution to environment, improve the Security of operation; Purge does not need to introduce nitrogen from the external world again, avoids foreign gas to be too much incorporated in ethylene oxide storage tank, causes material impure, affect downstream product quality; The utility model totally closed operation, without ethylene oxide gas discharging, does not need to arrange blow-down tank, saves equipment cost; Safety simple to operate; Reasonable in design, structure is simple, handling safety.Can loss of material be avoided, again can available protecting ethylene oxide transfer pump.
