Problems solved by technology

At least 20% of the energy consumption in the process of oil production, gathering and transportation in the oil field is used for heating and processing of crude oil. The traditional technology of heating crude oil during the transmission process usually uses coal, fuel oil, natural gas, and electric heating. method, which not only causes a large amount of energy consumption and serious environmental pollution problems, but also has a lot of potential safety hazards

Abstract

The invention relates to a controller of solar heating transmission device and relative method. The controller comprises a signal collector for detecting the environment parameters when transmitting base oil; an output execution device for starting the heating on the base oil transmission, and a control module for receiving environment parameters and controlling said device. Wherein, the control module is electrically connected to the signal collector and the output execution device; the control method comprises solar collection heating water circulation, heating circulation of water accumulation tank and the heat exchanger temperature-control. The invention can realize the control on the base oil transmission.

Description

technical field [0001] The invention belongs to the automatic control field of solar heating technology, and in particular relates to a control device and a control method for solar heating crude oil collection and transportation. Background technique [0002] At present, the oil field industry needs to consume a lot of energy in the process of oil production, gathering and transportation. my country's crude oil generally has a high freezing point, high viscosity, and poor fluidity at room temperature. Therefore, heating and heat preservation must be carried out during transportation after the oil is released from the oil well. At least 20% of the energy consumption in the process of oil production, gathering and transportation in the oil field is used for heating and processing of crude oil. The traditional technology of heating crude oil during the transmission process usually uses coal, fuel oil, natural gas, and electric heating. method, which not only causes a large am...
