Quick blank pipe type layering discharge device and quickly discharging method thereof

Abstract

The invention relates to a quick blank pipe type layering discharge device. The blank quick pipe type layering discharge device comprises a container and a heater, and further comprises a feeding pipe, wherein the container is provided with a discharge opening; the heater is arranged in the container and is arranged at the bottom of the container; the feeding pipe is communicated with the discharge opening and is sequentially provided with a plurality of discharge holes from top to bottom, and at least one discharge hole is arranged at the bottom of the container; and each discharge hole is provided with a switch control valve. The invention further discloses a quick discharging method for discharging by utilizing the quick blank pipe type layering discharge device. According to the invention, the technical problem that the discharge device in the prior art is too long in discharge time is solved, and the invention further provides the quick blank pipe type layering discharge device with short discharge time and a smooth discharge operation and the quick discharging method thereof.

Description

technical field [0001] The present invention relates to a discharge device and in particular, but not exclusively, to a discharge device suitable for heating and transporting and storing oil refinery residues, bitumen, sulfur or similar materials to be liquefied by heating, in particular to a The invention relates to an empty pipe type layered quick unloading device and a quick unloading method thereof. Background technique [0002] Oil refining residues, asphalt, sulfur and other products are solid or very viscous at room temperature. When transporting such products, they need to be heated to a temperature above their liquefaction point before they can be unloaded or loaded. For example, in the prior art In order to load, unload and transport asphalt, Chinese patent document CN102001500A discloses a petroleum asphalt tank container, including a frame, a tank body, a pressure reducing valve, a one-way valve, a discharge valve, two end cylinders, two support saddles, four A ...

AI Technical Summary

Problems solved by technology

[0003] The petroleum asphalt tank container in the above-mentioned patent documents uses a heating tube located in the container to heat the asphalt loaded in the container to above 120 degrees to completely liquefy the asphalt before unloading the asphalt through the unloading valve, and the heat conduction of the asphalt The performance is very poor. It often takes more than ten hours or even longer to completely liquefy the asphalt in a container weighing more than 20 tons. Not only the unloading time is too long, but also the container needs to be heated for more than ten hours. The energy consumption is very large, and the asphalt directly in contact with the heating container will also be carbonized due to long-term high-temperature heating, and the loss of the product every time it is heated and unloaded is large

[0004] According to the research of the inventors, during the heating process of oil refining residue, asphalt, sulfur and other products, the liquid materials in the bottom layer will rise after being heated by the heating tube, and the solid materials will sink. If the materials can be unloaded from the top to the bottom, it can greatly reduce However, products such as oil refining residues, asphalt, sulfur, etc. are not directly transformed from solid to liquid after being heated like water, but there is still a semi-viscosity state in the heating process. There is a discharge hole on the top, and the material below the discharge hole cannot be discharged, but if the discharge holes are arranged in sequence from the top to the bottom, the semi-viscosity material will enter the discharge hole and block the pipeline, so that the discharge device fail
