Description
Technical Field
The utility model belongs to the field of heat conduction oil expansion boxes, and particularly relates to a heat conduction oil seal protection device.
Background
Along with the rapid development of industrial technology, high-temperature heat carrier technology is advancing continuously, and heat conduction oil suitable for modern enterprises is generated, but in the practical production process, we can find that the wrong use mode can not make excellent heat conduction oil fully exert the effect. Therefore, the use technology and scientific management of the heat transfer oil are also very important in practical production.
The heat conducting oil is also called heat conducting oil, the normal name is heat conducting oil, the English name is Heat transfer oil, so the heat conducting oil, the heat kerosene and the like are also called. In the using process, the heat conduction oil is gradually cracked and carbonized because of long-term operation at a high temperature, so that coking is formed and deposited on the pipe wall. On one hand, the formed coking heat insulation layer reduces the heat transfer effect, increases the smoke discharging temperature and increases the fuel consumption; on the other hand, the temperature difference of the heating furnace tube can be rapidly increased due to the requirement of the production process temperature, and if the temperature difference between the inside and the outside of the furnace tube is increased to 600-700 ℃, the furnace tube is easy to burn through, so that fire safety accidents are caused. Therefore, the conduction oil furnace and the piping equipment must be regularly maintained and serviced.
In the practical application process of the heat conducting oil, a part of gas is generated in the heated heat conducting oil, and in order to avoid the gas flowing into the next circulation, the heat conducting oil is pumped into the high-level expansion oil tank for exhausting after one circulation is finished. In order to ensure the exhaust effect, the existing high-level expansion oil tank is provided with an exhaust port which is in through connection with the outside air, so that the balance of the internal pressure and the external pressure is ensured, and the exhaust is convenient.
However, this arrangement tends to result in the heat transfer oil within the expansion tank coming into contact with a significant amount of fresh air. The quality of the heat-conducting oil is deteriorated because the heat-conducting oil is easily oxidized after contacting with air.
In order to solve the technical problem, the heat conduction oil is not contacted with air, and the nitrogen can be used for sealing the heat conduction oil overhead tank. In this way, the nitrogen is in a consumed state because the air pressure in the expansion tank is continuously changed, and the operation cost is increased. In addition, certain difficulties exist in the implementation process of the nitrogen seal, and especially, certain small and medium-sized enterprises cannot effectively perform the nitrogen seal operation due to the reasons of management personnel and equipment.

first, the steady voltage pipe 5 opening part be equipped with the rain device.
Second, the top of the voltage stabilizing tube 5 is provided with an elbow, and the elbow enables the opening of the voltage stabilizing tube 5 to be downward.
The second arrangement is simpler and more efficient, and is therefore preferred.
