Embodiment Construction

[0018] In one embodiment of the present invention, the temperature detector detects the supply water temperature at the outlet of the circulation pump, and sends the supply water temperature to the controller, and then the controller compares the supply water temperature with the predetermined temperature, and controls the steam pipe located on the steam pipeline according to the comparison result. The actuator is used to control the amount of steam entering the steam heater in the steam pipeline, thereby achieving automatic adjustment of the steam and achieving the technical effect of high heat exchange efficiency. Further, the pressure value on the return water pipeline is detected by the pressure detector, and the automatic pressure relief of the pressure relief valve is started according to the pressure value, so that the technical effect of pressure stabilization is achieved.

[0019] In order to enable those skilled in the art to understand the present invention in more d...

Abstract

The invention discloses a steam-water hybrid heating apparatus for an oil field. The apparatus is connected with a steam pipeline of the oil field and comprises a steam-driven heater, a circulating pump, a temperature detector, a controller and an actuator. According to the invention, the temperature detector is used to detect supply water temperature at the outlet of the circulating pump and send the supply water temperature to the controller, then the controller compares the supply water temperature with predetermined temperature and controls the actuator located on the steam pipeline according to comparison results so as to realize control of the amount of steam entering into the steam-driven heater from the steam pipeline, and thus, the technical effects of automatic adjustment of steam and high heat exchange efficiency are obtained.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a heating equipment used for oil field steam-water mixing heating. Background technique [0002] One of the current heating methods of various large stations in Xinjiang Oilfield is steam heating, which mostly uses high-temperature and high-pressure steam generated by steam boilers as the heat source. After the heat is released, the high-temperature vapor-liquid two-phase mixture formed is discharged to the sewage tank. [0003] During the experiment, the inventor found that the prior art has the following deficiencies: [0004] After the high-pressure steam is decompressed, it fluctuates up and down with the change of the steam supply pressure, and the pressure is unstable. Due to the change of external environment temperature, the heat required for indoor heating is also changing. Artificially adjusting the steam supply pressure will affect the balance of system pre...
