Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automatic control, and in particular to an oilfield cloud edge energy storage control device. Background Art
[0002] The background of gas-fired heating furnace heating crude oil is mainly due to the fact that crude oil needs to be heated to maintain its fluidity during mining, processing and transportation. Especially in the production process of oil fields, crude oil needs to be heated after it is extracted from the ground to prevent it from solidifying and clogging the pipeline. The traditional heating method mainly uses a fire tube heating furnace or a tubular heating furnace. However, these heating methods have some problems, such as aging equipment, low efficiency, and rapid scaling. These problems will not only affect the service life of the heating furnace, but also have an adverse effect on the smooth progress of the entire processing process. With the continuous development of technology, gas-fired heating furnaces have gradually been widely used in the field of crude oil heating. However, since gas-fired heating furnaces use gas as fuel, it is necessary to pay attention to issues such as the safe use of gas and environmental emissions. In practical applications, the use of gas-fired heating furnaces also needs to be selected and configured according to the actual situation of the oil field. For example, the model and power of the heating furnace need to be determined according to factors such as the nature of the crude oil and the extraction temperature; the layout and safety protection measures of the heating furnace need to be determined according to factors such as the geographical conditions and climate environment of the oil field. The background of gas-fired heating furnace heating crude oil is based on the importance of crude oil heating and the problems of traditional heating methods. At present, crude oil gathering and transportation are still dominated by gas-fired heating furnaces in different forms. There are certain dangers in heating crude oil in gas heating furnaces, which are mainly manifested in the following aspects:
[0003] 1. Gas leakage: Gas heating furnace uses gas as fuel. If the gas leaks, it may cause fire, explosion and other accidents. Especially in the oil field production process, there are a variety of flammable and explosive gases, and the risk of gas leakage is greater.
[0004] 2 Excessive emissions: Incomplete combustion of gas heating furnaces may lead to gas waste and air pollution. If the incompletely burned gas encounters a suitable gas mixture, it may also cause explosions and other dangers. In addition, the gas composition is relatively complex, and it is difficult for gas furnace emissions to meet emission requirements.
[0005] 3. Scaling and corrosion: If the gas heating furnace is not properly handled during the heating of crude oil, scaling and corrosion may occur in the furnace. Scaling will affect the heat transfer efficiency of the heating furnace, and corrosion will cause equipment damage and accidents.
[0006] 4. Improper operation: The operation of a gas heating furnace requires professional knowledge and skills. Improper operation may cause equipment damage and accidents. For example, incorrect operation may cause gas leakage, incomplete combustion and other problems.
[0007] 5. Improper maintenance: Gas heating furnaces require regular maintenance and care. Improper maintenance may cause equipment damage and accidents. For example, failure to clean and inspect the heating furnace in time may cause problems such as scaling and corrosion.
[0008] Solar heating, as an energy-saving, environmentally friendly, safe and reliable heating method, has been used in other industries for a long time, but has only recently entered the field of crude oil heating. At the same time, the current system of using gas to heat crude oil has a sound control system, and there are fewer cases of using solar energy to heat crude oil. All of them are manually operated in local links, and there is no professional and sound control device so far. Utility Model Content
