Abstract
The utility model discloses an ethylene oxide discharging device which comprises a material storage tank and a tank vehicle. The ethylene oxide discharging device is characterized that the ethylene oxide discharging device further comprises a compressed nitrogen tank, wherein the compressed nitrogen tank is connected with the tank vehicle through a first pipeline, the tank vehicle is connected with the material storage tank through a third pipeline which is connected with the compressed nitrogen tank through a second pipeline, and the first pipeline, the second pipeline and the third pipeline are respectively provided with a plurality of switch valves. Due to the fact that ethylene oxide in the tank vehicle is squeezed and delivered into the material storage tank through compressed nitrogen which does not react with the ethylene oxide, the discharging device is sealed and safe in the whole material delivering process. Each switch valve is controlled to open and close when material discharging is in the last step, the residual ethylene oxide in the pipelines can be further delivered into the material storage tank, and the ethylene oxide is further prevented from leaking.
Description
Technical field
The utility model relates to chemical materials discharging technical field, particularly a kind of epoxyethane device for discharging.
Background technology
Epoxyethane is the important materials of Chemical Manufacture, mainly for the manufacture of ethylene glycol (polyester fiber raw materials processed), syndet, non-ionic surface active agent, antifreeze, emulsifying agent and condensed ethandiol series products, also for the production of plasticizer, lubricant, rubber and plastics etc., but epoxyethane has toxicity, and inflammable and explosive, therefore in the epoxyethane discharge process, to especially take care.
At present the epoxyethane in the tank car being discharged in the storage tank generally all is to realize by canned motor pump and corresponding pipeline, in case but canned motor pump takes place to leak or during poor sealing, can cause the leakage of epoxyethane, bring serious potential safety hazard.
The utility model content
The purpose of this utility model is to provide a kind of epoxyethane device for discharging that can safely epoxyethane be transported to storage tank, to address the above problem at deficiency and the defective of existing epoxyethane device for discharging.
The technical matters that the utility model solves can realize by the following technical solutions:
The epoxyethane device for discharging, comprise storage tank and tank car, it is characterized in that, also comprise a compressed nitrogen gas tank, described compressed nitrogen gas tank is connected with tank car by first pipeline, described tank car is connected with storage tank by the 3rd pipeline, and described the 3rd pipeline is connected with the compressed nitrogen gas tank by one second pipeline, is provided with at least one switch valve on described first pipeline, second pipeline and the 3rd pipeline.
In a preferred embodiment of the present utility model, described the 3rd pipeline is provided with the 3rd switch valve and the 4th switch valve, one end of described second pipeline is connected with duct section between the 3rd switch valve and the 4th switch valve, the other end of second pipeline is connected with the air extractor duct of compressed nitrogen gas tank, described first pipeline is provided with first switch valve, and described second pipeline is provided with the second switch valve.
In a preferred embodiment of the present utility model, described the 3rd switch valve is arranged near tank car discharge port position, and an end of described second pipeline is arranged on the discharge end of described the 3rd switch valve.
Owing to adopted technical scheme as above, the utility model utilizes compressed nitrogen that the extruding of the epoxyethane in the tank car is transported in the storage tank, nitrogen not with reacting ethylene oxide, whole feeding process sealingly secure, when proceeding to final stage, discharging closes the first, the 3rd switch valve, open the second, the 4th switch valve, the remaining epoxyethane of pipeline can also be transported in the storage tank, prevent that further epoxyethane from leaking.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to shown in Figure 1, the epoxyethane device for discharging comprises storage tank 300, tank car 200 and compressed nitrogen gas tank 100, tank car 200 is provided with admission port 210 and discharge port 220, compressed nitrogen gas tank 100 is connected with admission port 210 by first pipeline 310, compressed nitrogen is provided for tank car 200, pressure source is provided for tank car 200 dischargings.
Discharge process of the present utility model is as follows:
Close second switch valve 420, open first switch valve 410, the 3rd switch valve 430 and the 4th switch valve 440, the nitrogen of compressed nitrogen gas tank 300 enters in the tank car 200 and with epoxyethane and is transported in the storage tank 300 by the 3rd pipeline 330 at this moment, nitrogen not with reacting ethylene oxide, whole feeding process sealingly secure; Close the first, the 3rd switch valve when discharging proceeds to final stage, open the second, the 4th switch valve, this moment, nitrogen was transported to the remaining epoxyethane of pipeline in the storage tank, prevented that further epoxyethane from leaking.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
