Temperature sensors are respectively arranged at corresponding control points, which are required to be controlled, of the heat storage water tank, the solar collector, the air-source heat pump units and the oil storage tank, and the control device is respectively electrically connected with the temperature sensors by digital signal lines. The air-source and solar compound heating type crude oil storage and transportation system has the advantages that a viscosity and resistance reduction effect is remarkable, consumed energy can be reduced by 45% at least, and the air-source and solar compound heating type crude oil storage and transportation system has high economical benefit and high social benefit.

Description

technical field [0001] The invention relates to a heating system, in particular to a composite heating system of air source and solar energy [0002] The crude oil storage and transportation system is the full development and utilization of solar energy resources, and belongs to the technical field of crude oil heating storage and transportation. Background technique [0003] Crude oil with high wax content, high freezing point, and high viscosity must be heated and kept warm during the transportation process to maintain the good fluidity of the crude oil. There are mainly two traditional methods for heating and insulating oil storage tanks; one method is to burn coal, oil, gas and other mineral fuels to heat the oil storage tanks. This method not only consumes a lot of energy, but also has low system efficiency. It consumes a lot of metal materials, and has great potential safety hazards, complicated operation, large equipment footprint, and serious air pollution during th...

Problems solved by technology

One is single solar heating, which has the advantage of utilizing natural energy, saving energy and reducing consumption, but the disadvantage is that the start-up process is slow, and the system is seriously affected by solar irradiation conditions, resulting in unstable and discontinuous operation of the system; the other is single heat pump heating, which The advantage is that it is relatively less affected by the external environment and has better stability during work, but it has high requirements for the stability of low-temperature heat sources. The stability of low-temperature heat sources plays a key role in the efficiency of the system and the stability of operation. At the same time, the heat pump A cycle is a cycle that absorbs heat from a low-temperature heat source at the cost of consuming electrical energy

The existing technology has not effectively solved the problems of energy waste, environmental pollution and high production cost in the crude oil storage and transportation system
