Abstract

The invention discloses an automatic dehydrating and oil returning system for a siphoning type oil tank and an oil returning method. The automatic dehydrating and oil returning system comprises an oil tank, a dehydrator, a dehydrating pipeline for connecting the oil tank and the dehydrator and an oil returning system, wherein the oil returning system is connected with the dehydrating pipeline through a connecting pipeline; a connecting hole of the connecting pipeline and the dehydrating pipeline is formed in the top wall of the dehydrating pipeline; the oil returning system is composed of a buffer tank, a soft capsule and a controlling device; an inflation cavity and an inflation hole are formed in the soft capsule; the buffer tank seals the soft capsule in a tank body of the buffer tank; a gas outlet is formed in the buffer tank; and the controlling device is connected with the inflation cavity of the soft capsule or the gas outlet of the buffer tank. According to the automatic dehydrating and oil returning system disclosed by the invention, oil is isolated from air through the soft capsule and the sealed buffer tank, the deformation characteristics of the soft capsule is utilized, and the oil returning system is controlled to suck or discharge oil by changing the pressure in the soft capsule without a limitation of speed, so that the automatic dehydrating and oil returning system improves the oil returning efficiency and is safe and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of oil return systems for oil tanks, and in particular relates to a siphon type oil tank automatic dehydration oil return system and an oil return method. Background technique [0002] In order to meet the requirements of safety and environmental protection, an automatic dehydrator must be installed for oil tank dehydration. In order to ensure the continuity of dehydration, during the dehydration process, the oil entering the dehydrator must automatically return to the oil tank to continue dehydration. When the dehydration port of the storage tank is a siphon port, the oil in the dehydrator cannot automatically float back to the oil tank through the density difference, and the oil at the top of the dehydrator must be drawn back to the oil tank by external force. [0003] Patent No. 201420553227.4 discloses a breathing-type automatic dehydration and oil return system for siphon oil tanks, which uses water to ...
