Abstract
The utility model belongs to the technical field of chemical equipment, and particularly relates to a safe chloroethylene conveying system. The safe chloroethylene conveying system comprises a chloroethylene loading device, an automatic control system and a chloroethylene storage tank, wherein the automatic control system is composed of a safe conveying device, a chloroethylene stabilizing tank, a conveying pump and a pressurizing system. According to the safe chloroethylene conveying system, the situation that chloroethylene leaks in the positions of a chloroethylene liquid phase outlet and a gas phase inlet of a tank truck is avoided, and the situation that chloroethylene leaks in the positions of sealing pieces is avoided because the sealing pieces of existing conveying pumps are replaced by sealing materials made of teflon materials.
Description
Technical field
The utility model belongs to technical field of chemical, is specifically related to a kind of safe delivery system of vinyl chloride.
Background technique
Comprise the vinylidene manufacturing technology in food-grade polyvinylidene chloride resin complete device for producing commonly used at present.The raw material of making vinylidene chloride in this project is vinyl chloride.Vinyl chloride is to use the groove tank car be transported to factory and be transported in the vinyl chloride storage tank by conveying system device.Existing course of conveying is: after the groove tank car arrives the appointed place stop, use with the transfer line of the Simple quick connector of metallic hose respectively with after liquid phase, the gas phase excuse of groove tank car are docked, liquid phase vinyl chloride is drawn liquid in transfer pump, by transfer pump, vinyl chloride is transported in the vinyl chloride storage tank for production and application.For preventing that in course of conveying middle slot tank, the vinyl chloride pressure drop causes that transfer pump cavitation erosion occurs can not carry, be provided with gas phase vinyl chloride generating means, constantly carry vinyl chloride gas in the groove tank car by this device, make the higher pressure of the inner maintenance of groove tank car.
There are the following problems when practical application for above-mentioned feedway:
A. the Simple quick connector with metallic hose that is connected with the outlet of groove tank car exists in carrying installation and course of conveying the vinyl chloride leakage problem occurs, and has a strong impact on security of operation and the Environmental security of factory;
B. the vinyl chloride leakage easily occurs in the vinyl chloride transfer pump in carrying running, affects factory's security of operation and Environmental security;
C. non-persistent quality problem occurs in vinyl chloride, directly affects company's product quality.
The model utility content
The utility model overcomes above-mentioned deficiency and a kind of safe delivery system of vinyl chloride is provided, this system can avoid vinyl chloride liquid-phase outlet and gas phase ingress in the groove tank car that the leakage of vinyl chloride occurs, adopt the sealing material of teflon material to substitute the now Sealing of transfer pump, avoid Sealing place's vinyl chloride leakage.
In order to address the above problem, the utility model by the following technical solutions:
A kind of safe delivery system of vinyl chloride is characterized in that: this system comprises loads TOWER OUTLET IN VINYL CHLORIDE UNIT, automation control system and vinyl chloride storage tank; Described automation control system is comprised of security conveyer, the stable tank of vinyl chloride, transfer pump and pressurization system; In described loading TOWER OUTLET IN VINYL CHLORIDE UNIT, the liquid-phase outlet of vinyl chloride connects an entrance of security conveyer; An outlet of described security conveyer connects the entrance of the stable tank of vinyl chloride; The outlet of the stable tank of described vinyl chloride connects the entrance of transfer pump; Branch of described conveying delivery side of pump connects the vinyl chloride storage tank, carries the entrance of another branch's connection pressurization system of delivery side of pump; The outlet of described pressurization system connects another entrance of security conveyer; In described loading TOWER OUTLET IN VINYL CHLORIDE UNIT, the gas phase entrance of vinyl chloride connects another outlet of security conveyer.
According to above-mentioned safe delivery system, described security conveyer comprises the universal connecting structure that turns to, and this device adopts the sealing gasket of teflon material.
Positive beneficial effect of the present utility model:
The utility model system avoids vinyl chloride liquid-phase outlet and gas phase ingress in the groove tank car that the leakage of vinyl chloride occurs, and adopts the sealing material of teflon material to substitute the Sealing of existing transfer pump, avoids Sealing place's vinyl chloride leakage.
