Embodiment

[0008] Example: Take 10 x 10 4 m 3 Take the storage of Daqing crude oil in a single-disk floating roof oil tank as an example. The wax content of Daqing crude oil is about 30%, and the freezing point is 32.5°C. In the northern part of our country, heating and storage is required in autumn, winter and spring. In this type of oil storage tank, the original tank bottom heater is used, and the tank top heater and the vertical spiral steam pipe 2 heater are added. The structure of the tank bottom heater is as follows: Figure 4 , Figure 5 Shown, it is formed by 12 coils of 4 steam pipes, and steam pipe 12 is the steel pipe of 114, and total length is 1417m, and steam supply pressure is 0.4Mpa (gauge pressure). The structure of the tank roof heater is as follows figure 1 , figure 2 As shown, five horizontal steam pipes 1 are respectively connected to serpentine coils in a central small circle area and four equal small sector areas around them. The steam pipe 1 is made of 8...

Abstract

The present invention relates to a high solidification high-viscosity wax-containing petroleum product floating-roof-tank low-temp. stored space heating equipment. It is characterized by that on the tank bottom a bottom portion steam tube heater is mounted, under the floating roof a top horizontal steam tube heater is mounted, and is connected with 9-13 vertical helical steam tube heaters which are uniformly distributed in the oil tank, and the lower portion of vertical helical steam tube is connected with metal hose, then is connected to the water-discharging header of bottom portion.

Description

[0001] Involved areas [0002] The invention is a space heating device for low-temperature storage of high-condensation, high-viscosity waxy oil or residual oil floating roof oil tank. Involved in the field of piping systems. Background technique [0003] The traditional storage method for high-condensation, high-viscosity waxy crude oil or residual oil is to heat the oil to about 15°C above the freezing point and keep the temperature for storage. Generally, crude oil depots are basically designed according to the method of heating and heat preservation storage, that is, a heater is installed at the bottom of the tank to heat the crude oil, so that all the crude oil in the tank is in a liquid state and kept at a certain temperature for storage. The actual operating conditions vary depending on the region, the nature of the oil and the season, and the insulation temperature varies. The heater is installed at the bottom of the oil tank storing condensable crude oil. If the hea...
