A heating coil system for crude oil floating roof storage tank and using method

Abstract

The invention relates to the technical field of crude oil floating roof storage tanks, in particular to a heating coil system for crude oil floating roof storage tanks and a method for using the same. Modules and sliding rods, by setting the cleaning ring plate, and rotating the cleaning ring plate, the scraper scrapes the inner wall of the crude oil floating roof storage tank, and the crude oil floating roof can be effectively removed by scraping the inner wall of the crude oil floating roof storage tank. The sticky viscous substance on the inner wall of the storage tank after long-term use, on the one hand, makes the cleaning of the crude oil floating roof storage tank of the heating coil system easier, thereby reducing the burden of cleaning the crude oil floating roof storage tank for staff, thereby improving the heating The convenience of using the coil system, on the other hand, enables the spiral coil in the heating coil system to more efficiently transfer heat to the inner wall of the crude oil floating roof storage tank, thereby improving the heating coil system to prevent crude oil floating roof storage. The effect of crude oil condensation in a tank.

Description

technical field [0001] The invention relates to the technical field of crude oil floating roof storage tanks, in particular to a heating coil system for crude oil floating roof storage tanks and a method of using the same. Background technique [0002] Oil is the main fuel in today's society and one of the important raw materials for various chemical industries. Oil is called crude oil before it is extracted from the ground and unprocessed. Use crude oil floating roof storage tanks for storage, and then transport them by car, train or other means of transportation. When the temperature of crude oil is lower than the wax precipitation point, there will be a "condensation tank" phenomenon, resulting in safety accidents. Therefore, in When transporting a storage tank containing crude oil, the crude oil in the tank must be heated in a timely manner. At present, a heating coil system is usually installed in the storage tank to heat the crude oil in the tank, and this method has a...

Problems solved by technology

[0003] In the prior art, Chinese patent CN111792217B proposes a heating coil optimization method for large crude oil floating roof storage tanks, which can evaluate the effective energy utilization of different coil lengths for the heating process of crude oil storage tanks according to the effective utilization rate of comprehensive energy and the effective utilization rate of exergy. Finally, the optimal coil length is determined according to the heating effect and effective energy utilization, but it does not involve the influence of the heating coil system on heating the crude oil in the tank

Due to the poor fluidity of the crude oil itself, it takes time to heat the whole tank of crude oil through the thermal convection of the crude oil itself, thereby reducing the efficiency of use. The existing heating coil system is relatively close to the heating part of the system when heating the crude oil in the tank The crude oil can be sufficiently heated, but the crude oil in the farther area cannot be sufficiently heated, which leads to uneven heating of the crude oil. The existing heating coil system does not have the function of cleaning the attachments on the inner wall of the storage tank. During use, a thick layer of material will adhere to the inner wall, which will seriously affect the heat conduction of crude oil, thereby seriously affecting the treatment effect of the heating coil on crude oil condensation
