SU371130A1 - DEVICE TO REDUCE LOSSES FROM OIL EVAPORATION AND OIL PRODUCTS IN VERTICAL TANKS - Google Patents

Description

one

The invention relates to devices designed to reduce losses from the evaporation of light fractions, natrimer oil and oil products stored in steel vertical tanks.

A device is known for reducing the loss of oil from evaporating oil products in vertical tanks, including a carpet and a sealing closure made of synthetic material. However, in the well-known M device, it is impossible to tightly press the sealing gate against the walls of the reservoir without forming layers. In addition to this, there is insufficient buoyancy of the device.

In order to increase the efficiency of the device, the carpet is made of alternating in the ring and radial directions of rigid and elastic elements.

FIG. 1 shows: the device to be offered, general view; in fig. 2 is a section along A-A in FIG. one.

KoiBep 1 is made of synthetic material and consists of a central circle /, a ring of 2 of sixteen sections and a ring of 3 of thirty two sections. This is the central carrier part of the pontoon, made of rigid polyurethane foam. The ring 4 of the carpet is made of flexible polyurethane foam; ring 5 consists of sections of rigid polyurethane foam and

insert 6, made of flexible polyurethane foam; ring 7 is made of flexible polyurethane foam; ring 8 consists of sections made of rigid polyurethane foam, and inserted into 9 of flexible polyurethane foam.

The sealing shutter 10 is made of flexible polyurethane foam, covered with a polyurethane film.

Being located in the reservoir, the device floats on the surface of the liquid, thus excluding the possibility of evaporation of the light α-fractions.

The device in the tank is mounted in

pre-rolled condition with a 400 mm diameter reduction.

Elastic elements: sealing gate 10, inserts 9, 6 N of ring 7 and 4 are in the compressed state in the longitudinal and transverse directions, therefore the diameter and circumference are reduced.

The shutter due to the elastic deformation of elastic elements fits tightly against the wall of the tank.

Upward, the device rises under the action of the injected fluid. Downwardly descends along with the pumped out fluid under the action of its own weight. The shutter is pressed tightly against the walls of the tank, preventing evaporation of the light fractions.

The subject matter was invented and a device for reducing loss of evaporation of oil and petroleum products in vertical pesepiByapax, which includes a carpet and a sealing shutter made of synthetic material, characterized in that, in order to increase the work efficiency, the carpet consists of alternating in the annular and radial customization of stiff and elastic elements.
