Embodiment Construction
[0033] The technical solution of the present invention is described in more detail below in conjunction with the accompanying drawings and embodiments of the description:
[0034] Such as Figure 1-5 As shown, a sand bath type solid particle heat exchanger includes a shell 10, a shell side inlet 14, a shell side outlet 15 and a heat exchange part. The sealing plate 12 and the lower sealing plate 13 are composed, the shell side inlet 14 is arranged on the upper sealing plate 12, the lower sealing plate 13 is inclined, the shell side outlet 15 is set at the low point of the lower sealing plate 13, the shell side inlet 14, and the shell side outlet 15 is used for solid particle to enter and exit shell 10.
[0035] Inside the shell 10 is a heat exchange space for accommodating a heat exchange part. The heat exchange part is a heat exchange core 30 with a multi-layer heat exchange structure formed by winding a plurality of heat exchange tubes 31 on a central air blower 40. The cen...

The invention belongs to the technical field of heat exchangers, in particular to a sand bath type solid particle heat exchanger. Including the shell, the shell side inlet, the shell side outlet and the heat exchange part. The shell side inlet and the shell side outlet are respectively arranged on the upper and lower sides of the shell. The inside of the shell has a heat exchange space for the heat exchange part. The heat exchange part is wound by heat exchange tube The heat exchange core formed on the central blower, the central blower is connected with the blowing mechanism, the second blowing chamber is formed inside the cylinder, the wall of the central blower is provided with a blowing hole, and the shell is also provided with a shell A side air inlet and a shell side air outlet, the air inlet direction of the shell side air inlet is opposite to the air outlet direction of the blast hole. The invention adopts a cylindrical cylinder body, and the force effect is better than that of a rectangular cylinder body. The invention utilizes the opposite shell-side air intake and the blowing direction of the central blower to agitate the solid particles from the periphery and the center at the same time, and strengthen the solid particles in the exchange process. The turbulence in the heat chamber enables it to perform boiling heat exchange, which significantly improves the heat exchange efficiency.
Description
technical field [0001] The invention belongs to the technical field of heat exchangers, in particular to a sand bath type solid particle heat exchanger used for heat exchange between solid particles and liquid, gas or supercritical fluid. Background technique [0002] At present, in the solar tower photothermal power generation system, in order to better realize the utilization and storage of solar energy, solid particles are introduced as the intermediate medium, and the energy from the sun is absorbed on the central heat collection tower, and the heat transfer to supercritical CO 2 , using supercritical CO 2 The Brayton cycle generates electricity. About supercritical CO in the field of photothermal 2 The research and development of heat exchangers with solid particles is still in the research stage. In the existing technology, solid particles and supercritical CO 2 The heat exchangers between them include fluidized bed heat exchangers, shell-and-tube heat exchangers a...
