SU61658A1 - Device for the extraction of high-viscosity petroleum products, especially acid tar - Google Patents

Description

Existing devices for extracting and deoxidizing acid tars and other highly viscous petroleum products are very complex and often uneconomical. They consist of a series of uncoupled fixtures (grabs, conveyors, pumps, furnaces, etc.) and in most cases act periodically. The proposed device is free of these disadvantages.

The device (see drawing) is an elongated cylindrical bell 1, equipped with heating devices (coils or elements) 4 and connected to a vacuum pump. At the bottom of the bell has an inlet funnel 2, through which the tar flows.

Using a crane, the bell is immersed in a tarmac pond or reservoir, where it is lowered to the bottom by the action of its own weight. Turning on the heating - steam or electric, raise the temperature inside the bell to 100-200 °, depending on local conditions. The tar or fuel oil that has filled in the funnel 2, under the influence of the difference in the height of the pillars, heats up, softens and begins to pour over the edges of the inlet opening into the interior of the apparatus with a thin layer.

When it enters the atmosphere with a relatively high temperature, the tar quickly heats up, deoxidizes and drains into the lower part of the apparatus. Here, the accumulated liquid tar (or oil) closes the opening of the well-insulated outflow pipe 3. The pump attached to the top of the pipe evacuates the air; due to the pressure difference in the apparatus and in the pipe, liquid tar moves along it and thus REMOVES beyond the limits of the pond, where it merges into receivers (trolleys, tanks, barrels, kraft-cellulose bags, etc.).

The sulphurous gas and water vapors released during the heating of tar are discharged through pipe 5 passing through the apparatus’s crush, and with significant acidity they are evacuated by pipeline to the sulfuric acid plant or co-spring installation.

To protect the apparatus from various mechanical impurities (pieces of wood, stones, etc.) from falling into it, the lower part of the inlet conical tube is covered with a net 6. The net is periodically cleaned with a knife, set in motion by a handle pulled out of the sill.

Due to the total immersion of the apparatus in the tar or fuel oil, the heat radiated by the walls of the apparatus is used to heat and soften the layers of tar adjacent to them. Heat loss is minimized.

Subject invention

A device for extracting high-viscosity petroleum products, especially acid tar, from storages, made in the form of a bell immersed in the store, equipped with heating devices and connected to a vacuum pump for siphoning molten product, characterized in that a funnel is mounted inside the bell for selection product from hranilina1a and nodachi it to the suction pipe.
