[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

Embodiment Construction
[0035] In an optional implementation of this embodiment, a through hole 6081 is opened in the center of the top of the gear 608, and a stopper 6082 is fixed in the middle of the through hole 6081. The gear 608 is rotatably fitted between two limiting plates 6071, and the two limiting ring The board 6072 is inserted from the upper and lower ends of the through hole 6081, respectively.
[0036] In an optional implementation of this embodiment, the outer wall of the sliding rod 7 is vertically provided with a limiting groove 701, the size of the cross section of the limiting groove 701 is adapted to the size of the cross section of the stopper 6082, and the sliding rod 7 is positioned on the movable heat conducting ring. In the plate 601 and the adapter ring 604, the slide bar 7 runs through the limit frame 607 and the gear 608 through the limit ring plate 6072 and the through hole 6081 respectively, and the stopper 6082 is located in the limit groove 701, and the top of the fixed...

The invention relates to the technical field of crude oil floating roof storage tanks, in particular to a heating coil system for a crude oil floating roof storage tank and a using method.The heating coil system comprises a fixed bottom plate, a fixed top plate, a spiral coil, a lead screw, a movable cleaning module and a sliding rod; according to the heating coil system, the inner wall of the crude oil floating roof storage tank is scraped and swept by the scraping plate, and viscous substances adhered to the inner wall of the crude oil floating roof storage tank after long-term use can be effectively removed by scraping and sweeping the inner wall of the crude oil floating roof storage tank, so that on one hand, the crude oil floating roof storage tank of the heating coil system is simpler to clean; on the other hand, the spiral coil pipe in the heating coil pipe system can transfer heat to the inner wall of the crude oil floating roof storage tank more efficiently, and therefore the heating coil pipe system can be used for heating the crude oil floating roof storage tank, and the service life of the crude oil floating roof storage tank is prolonged. Therefore, the effect of preventing crude oil in the crude oil floating roof storage tank from being condensed by the heating coil system is improved.
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 an application method thereof. Background technique [0002] Petroleum is the main fuel in today's society, and it is also one of the important raw materials for various chemical industries. Petroleum is called crude oil before it is extracted from the ground and is 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 phenomenon of "condensation in the tank", which will lead to 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, the method of installing a heating coil system in the storage tank is usu...
