Abstract

The utility model relates to equipment used in a distillation system for producing petroleum products and used for respectively fractionating liquid and gas which are not mutually insoluble. The equipment comprises a closed cavity and an isolation structure; the cavity is provided with an inlet pipeline, a first outlet pipeline, a second outlet pipeline and a third outlet pipeline; the isolation structure divides the cavity into a fractionation cavity and a discharge cavity; the isolation structure is provided with a through hole and a communicating pipeline, and the through hole and the communicating pipeline are respectively communicated with the fractionation cavity and the discharge cavity; the cavity and the isolation structure are placed vertical to the ground; the through hole is positioned in the upper part of the isolation structure; one part of the communicating pipeline is arranged in the fractionation cavity and is parallel to the isolation structure, and the other part of the communicating pipeline is fixed in the isolation structure and communicated with the discharge cavity; and the upper pipe orifice of the communicating pipeline is positioned below the through hole, and the lower pipe orifice of the communicating pipeline is close to the bottom of the cavity. The equipment can improve the yield of the petroleum products, and does not depend on a manual adjusting valve so as to lighten the working strength.

Description

Be used for producing the liquid gas fractionation apparatus of the Distallation systm of oil product

Technical field

The utility model relate to a kind of Distallation systm that is used to produce oil product with immiscible liquid and the gas equipment of fractionation separately.

Background technology

Traditional single chamber liquid fractionating device; Can only lean on the manual adjustment valve control water yield; Along with the fluctuation of the difference and the tower equipment internal pressure of mixed liquor water amount, control valve needs frequent the adjusting, otherwise be prone to that water row does not come out or water in carry mixed liquor secretly; Cause the not cleer and peaceful mode of operation of separation to worsen, the high and product resource waste of thermal energy consumption.

Summary of the invention

The purpose of the utility model provides the fractionation and enter the device in the different pressures equipment voluntarily separately under the situation of pressure oscillation of a kind of immiscible liquids and gases.

The technical scheme of the utility model: this equipment comprises airtight cavity, and isolation structure disposes inlet pipeline, first outlet conduit, second outlet conduit, the 3rd outlet conduit on the cavity; Isolation structure is divided into fractionation chamber and discharge side two parts with cavity; Isolation structure is provided with through hole and connecting pipe, and through hole and connecting pipe are communicated with fractionation chamber and discharge side separately, wherein; The placement perpendicular to the ground of cavity and isolation structure; Through hole is on the top of isolation structure, and the part of connecting pipe is disposed in the fractionation chamber and is parallel with isolation structure, and another part is fixed in the isolation structure and with discharge side and is communicated with; The upper orifice of connecting pipe is below through hole, and the lower nozzle of connecting pipe is in the position near the bottom of cavity.

This equipment that the utility model provides can through the density of liquid difference in the fractionation chamber, separates the liquid of different densities and in discharge side the realization different pressures discharge; This fractionation apparatus can improve the yield of oil product, does not alleviate work thereby rely on the manual adjustment valve.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation: this equipment 20 shown in Figure 1 is made up of cavity 1 and isolation structure 2.The profile of equipment 20 is upper and lower airtight cavitys 1; Isolation structure 2 is divided into separately independently fractionation chamber A and discharge side B two parts with cavity 1; Isolation structure 2 upper ends are provided with the through hole 3 of gas phase circulation; Through hole 3 belows are provided with the connecting pipe 4 of separating liquid circulation, and the inlet pipeline 5 and first outlet conduit 6, second outlet conduit 7, the 3rd outlet conduit 8 are arranged on the cavity 1.The process flow diagram of this equipment of installation shown in Figure 2; Raw material is got into by the centre entrance 10 of tower equipment 9; The steam that heat is provided is got in the towers by the bottom inlet 11 of tower equipment 9 and blows steaming, and gaseous products is discharged by top exit 12, is the aqueous water that separates tower equipment 9; In tower equipment, be provided with disconnected tower tray 13, the mixed liquor of band aqueous water gets into this fractionating device by pipeline 14.Tower equipment 9 is realized pressure balance with separator 1 through pipeline 15.In this fractionating device fractionation chamber A, carry out the separation of water; One deck tower tray under anhydrous mixed liquor flows into through pipeline 16 voluntarily; Water enters discharge side B through the connecting pipe in the fractionation chamber 4; Because discharge side B and disengagement chamber A reach pressure balance through gas phase through hole 3, the water of disengagement chamber A can enter in the discharge side B automatically, and the interior water of discharge side is pressed in the equipment with atmosphere through gaseous pressure again; The mixed liquor of this belt transect aqueous water utilizes difference in specific gravity just can separate in separator A, acts on through gaseous pressure and realizes effluxing automatically of water on the liquid level of discharge.Even the fluctuation of the difference and the tower equipment internal pressure of mixed liquor water amount occurs, also can realize the balance of draining through the up-down of discharge side B liquid level.
