Description
Technical field
The utility model belongs to chemical tank apparatus field, relates generally to a kind of blow-down tank of safety dumping.
Background technology
Chemical industry tank equipment is the most basic unit of chemical plant installations, the tank equipment of water-oil separating and vapor-liquid separation of being used for adopts a variety of form according to being separated level difference, the most simply to count gravitational settling vapor-liquid separation mode, generally be used in separating rate and the not high occasion of purity requirement.Blow-down tank have employed the simplest vapor-liquid separation mode exactly, relies on vapour-liquid self gravitation difference to carry out reclaiming callable chemical industry material, gas emptying process.
The material of the blow-down tank process on different device is had nothing in common with each other, the material that the blow-down tank that mixed benzene separator designs relates generally to water, solvent, aromatic naphtha three kinds of intersections are dissolved each other.By designing and calculating, the material carrying out blow-down tank is after vapor-liquid separation, cooling, and containing the solvent of little water in allowed band and aromatic naphtha, liquid phase is discharged into wet solvent tank and reclaims, the process of gas phase safety vent.But due to aromatic hydrocarbons tower steam jet pump and regenerated solvent jet pump cooling effect poor, part benzene class aromatic hydrocarbon substance enters blow-down tank, and the water yield and aromatic hydrocarbons oil mass increase greatly, and the former designed use of blow-down tank there occurs change.Former design pot bottom control valve carries out cutting water and solvent naphtha, under aromatic naphtha intervention situation, because solvent is both water-soluble, is dissolved in aromatic naphtha again, if misoperation, aromatic naphtha may be cut out from pipeline, contaminated environment, and brings hidden danger to equipment safety production.A kind of blow-down tank solving water, solvent, aromatic naphtha safety dumping of Curve guide impeller for this reason.
Utility model content
The utility model discloses a kind of blow-down tank of safety dumping, mainly solve the safety dumping problem of water, solvent, aromatic naphtha.
The technical solution adopted in the utility model is:
A kind of blow-down tank of safety dumping, comprise tank body, tank body top is provided with material inlet, tank body is connected with float level meter, upper interface on described float level meter connection tank body and lower interface, described lower interface and drainage interface are located at tank base, and described upper interface is arranged in the middle part of tank body, above upper interface, a distance is oil extraction interface, and tank body top is also provided with material outlet.
In order to the environment of Real-Time Monitoring tank body inside, described tank body top is also provided with pressure gauge connection, thermometer boss, to measure internal pressure and temperature.In addition, the conveniently maintenance of blow-down tank and maintenance, tank body top is also provided with manhole.
Preferably, on float level meter, above interface, 100mm place is oil extraction interface, when oil level reaches oil extraction interface, flows to outside slop tank, reclaims aromatic hydrocarbons.The non-oil liquid level of float level meter remains on about 60% to ensure the place of safety of solvent and aromatic naphtha.
In addition, tank base is provided with leg, supports overall structure.
The advantage that the utility model has and beneficial effect are:
The utility model solves the deficiency in the design of mixed benzene separator blow-down tank, and the working method adopting control valve and float level meter to combine, utilizes float level meter to measure liquid level and interface, water and aromatic naphtha are discharged from distinct interface respectively.Further, during discharge, ensure enough safe distances, aromatic naphtha can not be discharged from drainage interface, ensure safety dumping.
Tank structure is simple, and accessory is easy, easy and simple to handle.

Fig. 1 is structural representation of the present utility model;
In figure, interface 5-oil extraction interface 6-material outlet 7-thermometer boss 8-manhole 9-lower interface 10-leg 11-tank body on 1-drainage interface 2-material inlet 3-pressure gauge connection 4-
Detailed description of the invention
Be below a kind of specific embodiment of the present utility model:
As shown in Figure 1, a kind of blow-down tank of safety dumping, comprises tank body 11, and tank body 11 top is provided with material inlet 2, material outlet 6, pressure gauge connection 3, thermometer boss 7 and manhole 8.Be provided with oil extraction interface 5 in the middle part of tank body 11, bottom tank body 11, be provided with leg 10 and drainage interface 1.
Because solvent is miscible between water oil, make water, solvent, aromatic naphtha not have obvious boundary, the simple control valve that leans on regulates dangerous automatically.The utility model bottom tank body 11 and middle part get the float level meter that an installation length is 1000mm, float level meter connects upper interface 4 and lower interface 9.By control valve, by tank, water, solvent are by the tangential external solvent tank of drainage interface 1, and on float level meter, interface 4 is apart from 100mm place installation one oil extraction interface 5, when oil level reaches oil extraction interface 5 place, certainly flows to outside slop tank, reclaims aromatic hydrocarbons.The non-oil liquid level of float level meter remains on about 60% to ensure the place of safety of solvent and aromatic naphtha.
The utility model specific works process is:
Logistics from each drain of device enters blow-down tank through material inlet 2, cools back the water of the solidifying liquid state obtained, solvent, aromatic naphtha fall at the bottom of tank through self gravitation sedimentation and outlet upper end cooler.Water, solvent are discharged through drainage interface 1 by governor valve control, and aromatic naphtha both flowed out tank body 11 from oil extraction interface 5 after reaching the oil extraction interface 5 on float level meter above interface 4.Fail the gas phase of sedimentation condensation and discharge emptying process by material outlet 6.Tank body 11 top pressure table interface 3, thermometer boss 7, built with site pressure table, thermometer, ensure tank body 11 safety index.
