When in use:
1. the system starts the preparation work:
1.1, injecting heat conduction oil:
according to the heating flow and requirements, regulating a system valve, starting a main oil pump, and then injecting heat conduction oil into a circulation system and an expansion tank; at the same time, the vent valve is actuated to vent air. Careful examination of the system operation ensures that there are no problems with conduction oil bleed-out or similar leakage.
1.1.2, cold oil circulation:
when the glass liquid level indicator shows the oil filling height, the circulating pump can be started, the working condition of the circulating pump needs to be concerned at any time, the emptying valve is started regularly, and the air in the system is discharged as much as possible. The operating pressure may fluctuate significantly during the cold oil cycle, affected by the air inside the system. If the pressure fluctuation range is too large and the circulating pump is empty, stopping the pump for 2-3 min, and restarting the circulating pump; this practice has proven to be effective in controlling the amplitude of pressure fluctuations.
1.2, starting heating:
igniting the cold furnace, heating up at a speed of 10 ℃/h, reducing the heating up speed to 5 ℃/h when the temperature reaches 90-95 ℃, and dehydrating. According to the residual moisture and heat conduction oil quality in the system, the dehydration time length and the system temperature are determined, and blind temperature rise cannot be recorded, so that the system is exploded, and further safety accidents are caused. After the noise of the pipeline and the heat conduction oil furnace is reduced and the outlet pressure is reduced to 0.1MPa, the temperature is raised at the speed of 5 ℃/h, the temperature is changed to constant temperature when the temperature reaches 120 ℃, and the gas in the blow-down pipe is discharged out in a plurality of times, so that the process can be smoothly transferred to the next process.
1.3, parking operation:
1.3.1, normal parking:
the steps for normal parking are as follows: firstly, cutting off the current of an electric heater according to a stopping plan to ensure that the heat conduction oil furnace can stop burning in time; meanwhile, the hot oil circulating pump should maintain normal operation, avoid the continuous rise of the temperature of the heat conducting oil in the furnace tube, and stop the pump when the temperature of the oil outlet is reduced to below 80 ℃. And secondly, selecting a fire pressing method according to the stopping time, and if the temperature of the outlet oil still fails to drop below 80 ℃ in a fire pressing state, starting a hot oil circulating pump as soon as possible. Oil is discharged by fully combining the condition of the overhauling part, and corresponding cooling facilities are started. Finally, the production is resumed with reference to the hot test run.
1.3.2, emergency stop:
emergency stop should be performed when the following accidents occur in the production process: firstly, an unplanned power failure; secondly, pump out failure of the circulating pump; thirdly, the running temperature and the pressure of the system exceed the allowable range; fourthly, the pipeline equipment is damaged or obvious cracks appear. The emergency stop needs to stop the operation of blowing and coal feeding, discharge the fire coal through the fire grate, and stop the operation of the electric heating and gas heating system. It is generally not necessary to terminate operation of the circulation pump except in very specific situations. If the workshop fails, the operation of extinguishing fire by steam, pressing fire by wet coal and the like is carried out, the hot oil in the furnace tube is discharged, and the cold oil with the same quality is injected, so that the hot oil is prevented from aging or decomposing rapidly due to the fact that the temperature exceeds the allowable range.
Nitrogen sealing system and corresponding device:
the nitrogen sealing system carried in the system mainly comprises a bypass pipe, a breathing pipe, a nitrogen pipe, a high-level oil groove and other devices. One end of the breathing tube is connected with the high-level oil groove, and the other end of the breathing tube is divided into two branch pipes; wherein the inhalation branch is provided with an inhalation valve, and the exhalation branch is provided with an exhalation valve, and the exhalation valve is connected with the bypass pipe. One end of the nitrogen pipe is also connected with a high-level oil groove, and the pipeline is provided with a nitrogen leakage valve and a nitrogen supply valve. A pressure gauge is arranged between the bypass pipe and the high-level oil groove and is responsible for monitoring the nitrogen pressure in real time.
The specific operation of the nitrogen seal system is as follows: the oil groove surface is covered with a layer of protection nitrogen, and staff can adjust the nitrogen pressure through the protection device. In the oil discharging state, the liquid level of the storage tank is continuously reduced, and at the moment, the opening of the nitrogen supply valve can be increased as appropriate, so that the pressure in the storage tank can meet the requirement; in the oil inlet state, the liquid level of the storage tank rises rapidly, the nitrogen pressure also rises along with the compression of the gas phase volume, the nitrogen supply valve is closed and the nitrogen release valve is started at the moment, and the pressure in the storage tank is reduced to the rated value in a nitrogen discharge mode.
In addition, in order to further improve the storage tank safety coefficient, the tank top is further technically improved, and a breather valve is additionally arranged, so that even if the nitrogen leakage valve and the nitrogen supply valve cannot normally operate, the safety of the storage tank can be ensured by opening the breather valve.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
