Embodiment 1

[0028] Embodiment 1: a kind of electric heating heat storage heat exchanger, such as Figures 1 to 6 shown. The device includes a housing 5, which is in the shape of a pot with an upper opening, and the upper opening is sealed with a cover plate 7 that can be hoisted and disassembled. The heat storage medium 11 is filled in the casing, and the heat storage medium is a medium capable of phase-change heat storage. Four filling ports c are arranged on the circumference of the upper end of the casing, and a heat storage medium discharge port is arranged at the bottom end of the casing. The shell is provided with a heat exchange pipe 2, such as figure 1 , 2 As shown in , the heat exchange pipe turns back up and down in the vertical plane and coils in a serpentine manner, as shown in Figure 4 As shown in the figure, the heat exchange pipes are arranged in a meandering way back and forth on the horizontal plane, covering the interior of the shell. Such as figure 2 , 6 As sho...

Embodiment 2

[0031] Embodiment 2: An electric heating heat storage heat exchanger in which the distribution density of the heat exchange pipes is designed according to the position of the inlet and outlet of the heat exchange pipes, such as Figure 1 to Figure 3 , Figures 7 to 9 shown. The device includes a housing 5, which is in the shape of a pot with an upper opening, and the upper opening is sealed with a cover plate 7 that can be hoisted and disassembled. The heat storage medium 11 is filled in the casing, and the heat storage medium is a medium capable of phase-change heat storage. Four filling ports c are arranged on the circumference of the upper end of the casing, and a heat storage medium discharge port is arranged at the bottom end of the casing. The shell is provided with a heat exchange pipe 2, such as figure 1 , 2 As shown in , the heat exchange pipe turns back up and down in the vertical plane and coils in a serpentine manner, as shown in Figure 7 As shown, the heat exc...

Abstract

The invention relates to an electrically-heated energy-storage heat exchanger and a heat storing and releasing method thereof and solves the problems of non-uniform energy distribution and low energy utilization rate in the heat exchange process of an existing electrically-heated phase change heat storage and exchange device. The electrically-heated energy-storage heat exchanger comprises a tank-shaped shell and an electric heating pipe; the shell is filled with a heat storage medium. The electrically-heated energy-storage heat exchanger is characterized in that a heat exchange pipeline is also arranged in the shell and is vertically folded back in a vertical plane to be coiled in an S-shaped manner; the heat exchange pipeline is folded to and fro in a horizontal plane to be arranged in an S-shaped manner or spirally arranged inside the shell around a circle center; an opening is formed in the upper end of the shell, and a detachable cover plate is arranged at the upper end of the shell; an inlet and an outlet of the heat exchange pipeline penetrate out of the shell from the cover plate; the electric heating pipe extends into the inside of the shell downwards from the cover plate. The electrically-heated energy-storage heat exchanger provided by the invention performs uniform heat exchange on the heat storage medium with poor mobility, so that the heat utilization efficiency is improved.

Description

technical field [0001] The invention relates to a heat storage device, in particular to an electrically heated heat storage heat exchanger and a heat storage and release method thereof. Background technique [0002] Since China's reform, the economy has developed rapidly, and now its GDP ranks second in the world. China is also experiencing environmental problems experienced by Western developed countries. The large-scale use of primary energy coal and oil in the development process has led to increasingly serious environmental problems. , air pollution, climate warming. In recent years, smog has occurred frequently in many places in my country, seriously affecting people's daily life and health. To this end, the State Council and various provinces and cities have issued air pollution prevention and control policies and implementation plans. Comprehensive rectification and elimination of small coal-fired boilers have been put on the agenda, and "coal to gas" and "coal to e...
