SU1402508A1 - Arrangement for unloading railway tanks filled with high-viscous petroleum products - Google Patents

Abstract

The invention can be used when unloading highly viscous or solidifying petroleum products, for example fuel oil, in railway tanks. The aim of the invention is the complete emptying of the tank and an increase in the intensity of the flow along the oil discharge pipe. The device contains a source of heated heated gas 1, a pipeline 2 for supplying gas to the tank 3 and a pipeline 4 for further transporting the discharged product 5 and performs a thermopneumatic method of unloading product 5 and cleaning the tank 3. Hot gas from source 1 enters the tank 3 through sleeve 6, squeezes the product out of the tank through the drain pipe 12 and dilutes the remaining product adhering to the walls of the tank 3, which ensures complete emptying. The ejector I, mounted on the sleeve 7, ensures that the gas transfers additional energy to the product and an increase in the intensity of its flow in the pipeline 4. 1 sludge. (L

The invention relates to the railway transport of petroleum products and can be used for carrying out drainage and loading operations when loading and unloading high-visibility or sewage when transporting in (railway oil tankers, for example, fuel oil).

The purpose of the invention is the complete emptying of the tank and an increase in the intensity of the flow of the product along the conduit drain

I Running a pipeline for supplying the heated gas to the tank with the increased pressure in the form of two sleeves, O | E (the IN of which is connected to the tank inlet and the other to the branch pipe, leads to liquefaction of the stuck tank) m & jute and to heat the fuel oil in the area of the vent pipe, resulting in an increase in the outflow of fuel oil and complete empty tank, while supplying the arm for supplying gas to the drain nozzle with an electrode provides the gas with additional energy for fuel oil and an increase in the intensity of the heat-trap through the discharge pipe.

 The drawing shows the scheme of the device.

; The device for unloading railroad tank cars with high-viscous oil products consists of a source of heated gas 1 of increased pressure, a pipeline 2 for supplying gas to tank I 3 and a pipeline 4 for the further transportation of unloaded product 5, pipeline 2 you - pflnen in the form of two sleeves 6 and 7 "The handler 6 is equipped with a fitting 8 with a reduction-HiiiM valve, while fitting 8 is extruded with the possibility of connection with the bulk branch pipe of the tank, and the valve m-reducer 9. Sleeve 7 contains the valve 10 and the ejector P. The latter is filled with cylindrical the mixing chamber and the nozzle and docked with T1 uboprovodom 4 and the spout

12, on which the valve is mounted

13. The source 1 of the heated pressurized gas contains a diesel compressor unit I4 and a heat exchanger 15. The heating element of the heat exchanger 15 is made in the form of a coil 16, which discharges diesel exhaust gases 17. The compressor 18 is

the inlet is coupled to the radiator 19 of the diesel 17, and the outlet to the inlet of the heat exchanger 15. The outlet of the heat exchanger 15 is connected to the inlet of the pipeline 2 for supplying gas to the tank 3.

The device works as follows.

Before unloading when the valve 10 is open, the hot gas heats up the ejector 11, the drain pipe 12 of the tank 3 and blows the pipeline 4. At the same time, the gas through the sleeve 6 through the valve-reducer 9 and the socket 8 enters the tank 3 and creates a high pressure in the tank 3 above the fuel oil 5. Then open the valve 13 and the fuel oil 5 under the action of gas pressure is squeezed out through the drain pipe 12 to the ejector 1I. When this occurs, the fuel oil is heated in the drain pipe 12 and the intensity of the outflow of fuel oil increases. In the ejector 11, the fuel oil is mixed with a stream of hot gas and transported via pipeline 4 to the place of storage or consumption as a fuel oil-gas emulsion. As a result of the transmission of additional energy by the fuel oil, the intensity of its flow in the pipe 4 increases. At the same time, the hot gas supplied to the tank 3 through the sleeve 6 dilutes the fuel oil sticking to the walls of the tank 3, the fuel oil flows to the discharge nozzle 12, which ensures complete . emptying the tank 3,
