Embodiment 1

[0033] Such as Figure 1-2 As shown, a large-capacity hot water storage pool includes a hot water storage body 5, the liquid level of the hot water storage body 5 is lower than the level of the surrounding cofferdam 6, and the side surface of the hot water storage body 5 is arranged between the soil or other supporting materials 11 The side flexible barrier layer 1, the side flexible barrier layer 1 extends out of the water body 5, reaches or approaches the height of the cofferdam 6 and then descends to form a bottom groove 12 under the cofferdam 6, and the bottom of the bottom groove 12 is filled with a high-porosity porous medium 7. Such as but not limited to gravel; the top of the bottom groove 12 is filled with a low-porosity porous medium 8, such as tiny stones or sand. The top flexible barrier layer 2 is arranged between the liquid surface of the hot water storage body 5 and the top floating insulation layer 3, and the top flexible barrier layer 2 extends out of the wate...

Abstract

The invention relates to a microchannel gas discharging and water draining device for a large-capacity heat storage sink. A side face flexible obstructing layer arranged on the side face of a heat storage water body and a top flexible obstructing layer arranged on the surface of the heat storage water body are included; the side edges of the side face flexible obstructing layer and the top flexible obstructing layer stretch onto a cofferdam of the heat storage sink and then are overturned outwards downwardly to form a bottom groove and an upper groove correspondingly; the upper groove is located above the bottom groove; the space between the upper groove and the bottom groove is filled with a porous medium material, and a micro channel is formed; and gas formed in the heat storage water body or water overflowing outwards is discharged out of the micro channel. The device solves the problems that because gas in the heat storage water body cannot be discharged out, a heat preserving cover deforms, is dislocated and the like.

Description

technical field [0001] The invention relates to an exhaust and drainage device for a heat storage pool. Background technique [0002] Energy storage technology is the key to efficient utilization of renewable energy such as solar energy and wind energy, among which heat storage energy storage technology is an important way of energy storage. After years of development, different technical fields have been formed. In the past, the research on heat storage technology mainly focused on artificial water tank (tank) heat storage, water gravel heat storage, soil heat storage and underground aquifer heat storage, etc. At present, domestic solar thermal utilization systems mostly use artificial water tank short-term heat storage (about 2-3 days) technology, which can only meet the needs of domestic hot water, and cannot achieve long-term storage and utilization of heat energy across summer and winter, and cannot meet the wide application of building heating. need. Large-scale art...
