Description

Technical Field

[0001] The utility model relates to the technical field of a hydrophobic expansion container, in particular to a hydrophobic expansion container for a heavy oil heater. Background Art

[0002] The function of the hydrophobic expansion tank is to remove the water vapor from the system when the heater heats the liquid, and to process the generated gas to maintain the normal pressure and flow inside the system. However, when it is used, the heavy oil heater usually produces oil smoke during the heating process. This is due to the partial combustion or volatilization of heavy fuel (such as fuel oil or petroleum) during the heating process. These oil fumes may contain particulate matter and other residual substances. These substances will adhere to the inside of the hydrophobic expansion tank and accumulate inside the equipment, which is easy to affect the normal flow of the fluid and cause the equipment to operate poorly. For example, a Chinese patent discloses a "hydrophobic expansion tank for heavy oil heater", and its application number is "201320373809.X". This device includes a vertical cylinder with upper and lower cylinders. Both ends are connected with heads. The upper head of the cylinder is provided with a steam outlet, a pressure gauge port, a thermometer port and a safety valve port. The bottom of the lower head of the cylinder is provided with a drain outlet. The cylinder is provided with a liquid level measuring device. There is also a manhole on the side of the cylinder. The lower part of the side of the cylinder is provided with a drain inlet with a water inlet pipe. The water inlet pipe is connected to the cylinder along a tangential direction. The manhole of this equipment is arranged on the side of the cylinder for easier maintenance and personnel entry. The water inlet pipe is connected to the cylinder in a tangential direction for better water flow distribution. However, when it is used, the heavy oil heater usually produces oil smoke during the heating process. The oil smoke may contain particulate matter and other residual substances. These substances will adhere to the inside of the drain expansion tank and accumulate inside the equipment, which can easily affect the normal flow of the fluid and cause the equipment to operate poorly.
