Solar/off-peak electric compound energy conduction oil heating supply system

Abstract

The invention relates to a solar / off-peak electric compound energy conduction oil heating supply system, formed by a concentrating solar collector, an electric heating conduction oil boiler, a heat accumulator, a heat exchanger, and a heat consuming device which are connected through pipes. The oil-conveying pipe of the concentrating solar collector is connected with the lower part of the heat accumulator. The hot oil pipe of the concentrating solar collector is connected with the hot oil inlet of the heat accumulator. The oil inlet pipe and the oil outlet pipe of the electric heating conduction oil boiler are respectively connected with the oil outlet and the oil inlet on the lower part of the heat accumulator. The hot oil inlet pipe and the oil return pipe of the heat exchanger are respectively connected with an upper part hot oil outlet and a lower part oil return port of the heat accumulator. The hot oil pipe and the oil return pipe of the heat consuming device are respectively connected with the hot oil outlet and the oil return inlet of the heat exchanger. The concentrating solar collector is used to reduce to consume conventional energy to the largest extent. The heat accumulator is used to store heat energy, balancing heat generated by the system and thermal load of heat consumption. Off-peak electricity of a power grid at night is used as an auxiliary energy, so that normal heat supply of the system is not influenced by weather factors.

Description

technical field [0001] The invention belongs to the technical field of heating engineering systems, and relates to a solar energy / low valley electricity composite energy heat conduction oil heating system. Background technique [0002] Solar energy low-temperature photothermal technology has been widely used in this field, but the application of medium-high temperature photothermal technology has not been popularized so far. The main reason is that the instability of solar energy seriously restricts the application of medium-high temperature photothermal technology. .
