Abstract

The invention discloses a heavy oil storage tank dehydration device which is composed of a float (6), a drainage folding tube (8), a guide bar (4), a balance arm (3) and a drainage straight tube (9). The middle of the balance arm is provided with a water inlet (11) which is communicated with one end of the drainage folding tube (8), and the other end of the drainage folding tube (8) is communicated with the drainage straight tube (9). The float (6) is communicated with the balance arm (3) which moves along the guide bar (4). The equipment provided by the invention has a simple structure, is convenient to install, has less investment, and is convenient to operate.

Description

Technical field: [0001] The invention relates to a device for separating hydrocarbon oil and water, in particular to a device for removing water in a heavy oil storage tank. technical background: [0002] At present, the density of most petroleum and its distillates is less than that of water. For this type of oil storage tank, the water is located in the lower part of the oil storage tank, and the water is dehydrated through the dehydration pipe at the lower part of the storage tank. Remove water. The proportion of heavy oil and low-quality oil is getting higher and higher, especially the heavy fraction of heavy and low-quality oil accounts for an increasing proportion of crude oil. These heavy oils have a high density, and some have a specific gravity greater than 1.0. The water in the oil will be located in the upper part of the heavy oil, and the water cannot be removed through the dehydration pipe at the lower part of the storage tank. The water will accumulate in the ...
