Description

Technical Field

[0001] This utility model relates to the field of thermal energy storage technology, and in particular to a biomass thermal energy storage heating device. Background Technology

[0002] With increasing global emphasis on carbon emissions, the demand for biomass combustion power generation, thermal storage, and heating is growing.

[0003] A search revealed a patent document with publication number "CN212987343U" disclosing a biomass renewable energy low-carbon urban heating centralized heating device. This device comprises a heat exchange tower, a vaporization tower, a heating tower, an injection well, a production well, an injection well air compressor, a production well air compressor, a return water pump, a heat pump, a membrane module, a membrane module air compressor, a filter, a dust collector, a separator, and heat transfer pipes. These components are connected mechanically, through pipelines, and electrical circuits, forming a comprehensive biomass renewable energy low-carbon urban heating centralized heating device. This device consumes only electricity and water; the biomass fuel undergoes no further processing and is directly vaporized and burned. The cost of urban centralized heating is reduced by approximately 50% compared to coal-fired heating and by approximately 70% compared to natural gas-fired heating.

[0004] Based on the above research and existing technology, it has been found that most existing biomass thermal energy storage and heating devices use heat exchange towers for thermal energy storage and release (heating). However, existing heat exchange towers generally adopt a synchronous heat exchange operation mode, that is, water and gas are introduced simultaneously and heat is exchanged using the internal filling medium (heat exchanger, heat exchanger, heat storage medium, etc.). Although this method can achieve the effect of timely heating, the filling medium in the heat exchange tower cannot store heat well, which does not meet the thermal energy storage requirements. If an asynchronous method is used (that is, high-temperature gas is introduced first for thermal energy storage, and then water is introduced for thermal energy release (heating)), although the thermal energy storage requirement is met, it cannot perform rapid heat exchange simultaneously, resulting in low efficiency. This makes it inconvenient to use as thermal energy storage and heating cannot be carried out at the same time. Therefore, a biomass thermal energy storage and heating device is needed.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Reference Figures 1-4 The biomass thermal energy storage and heating device shown includes a tower body 1. The upper and lower ends of the tower body 1 are respectively provided with an air outlet 12, a return water inlet 13, an air inlet 15, and a return water outlet 16. The positions of the air outlet 12 and the air inlet 15 are vertically aligned, and the positions of the return water inlet 13 and the return water outlet 16 are vertically aligned. The tower body 1 is equipped with a layered partition 2 that divides the tower body 1 into multiple filling cavities 14. Each filling cavity 14 is filled with a filling medium (heat exchanger, heat transfer medium, heat storage medium, etc.) capable of storing heat.

[0026] Each filling cavity 14 is equipped with a vertical partition 3. Multiple partitions 3 are provided to divide the filling cavity 14 into multiple non-connected areas. One area corresponds to the position of the air outlet 12, and the other area corresponds to the position of the return water inlet 13.

[0027] A drive shaft 4 is rotatably connected inside the tower body 1. The drive shaft 4 is coaxial with the tower body 1. The drive shaft 4 rotates through multiple layered partitions 2, and the drive shaft 4 is fixed to multiple partitions 3 around its periphery.

[0028] The upper end of the tower body 1 is equipped with a drive structure that drives the drive shaft 4 to rotate.

[0029] Based on the above structure, after the filling cavity 14 is divided into multiple areas (three in the figure of this embodiment) by multiple partition plates 3, air and water can be introduced at the same time for heat exchange, and they will not affect each other. This achieves the purpose of simultaneous heat storage and heat release, making it more convenient to use and providing better heat storage and heating effects.

[0030] Furthermore, the partition 3 includes a main body 31, the upper and lower ends of which respectively abut against the bottom wall or top wall of the tower body 1 and the layered partition 2. The width of the partition 3 is greater than the width of the through hole on the layered partition 2.

[0031] Both the upper and lower ends of the main body 31 are integrally formed with a scraper part 32, and the side of the scraper part 32 away from the main body 31 forms an inclined chamfer.

[0032] By setting up the main board 31 and the scraper part 32, the filling cavity 14 can be divided, and the filling medium filled in each area can be pushed, so that the position of the filling medium storing or releasing heat energy changes, thereby achieving the purpose of simultaneous heat storage and heat supply. The scraper part 32 can scrape up the filling medium in contact with the main board 31, avoiding large wear between the filling medium and the edge of the main board 31 during movement.

[0033] Furthermore, a hollow cavity 311 is formed inside the main body 31, and the hollow cavity 311 is filled with a thermal insulation medium 33. The thermal insulation medium 33 is made of thermal insulation materials commonly used in the prior art and applicable to this embodiment (such as foamed ceramic materials, glass wool, etc.), which enables the main body 31 to have a good thermal insulation effect, thereby achieving the purpose of reducing the temperature transfer efficiency of the filling medium in each area and generating a relatively separated heat storage and heating effect.

[0034] Furthermore, the drive structure includes a drive motor 5 and a reducer 6. The drive motor 5 is fixed to the top of the tower body 1. The input end of the reducer 6 is connected to the output shaft of the drive motor 5, and the output end of the reducer 6 is connected to the upper end of the drive shaft 4. After the drive motor 5 starts, it drives the drive shaft 4 to rotate through the reducer 6. When the drive shaft 4 rotates, it drives multiple partition plates 3 to rotate, thereby pushing the filling medium in the filling cavity 14 to move to different areas (here referring to the areas corresponding to the air outlet 12 and air inlet 15, or the areas corresponding to the return water inlet 13 and return water outlet 16, or areas that do not correspond to either), to meet the needs of the filling medium for heat storage and heat release.

[0035] In addition, a number of observation windows 11 are fixedly embedded on one side of the tower body 1. Each observation window 11 corresponds to a number of filling cavities 14, which facilitates observation of the state of the internal filling medium.

[0036] The working principle of this utility model is as follows: During daily use, after the drive motor 5 starts, it drives the drive shaft 4 to rotate through the reducer 6. When the drive shaft 4 rotates, it drives multiple partition plates 3 to rotate, thereby pushing the filling medium in the filling cavity 14 to move. This causes the filling medium to move to different areas. When the filling medium is located in the area corresponding to the air outlet 12 and the air inlet 15, the filling medium absorbs the heat of the flowing gas and achieves heat storage. In the area corresponding to the return water inlet 13 and the return water outlet 16, the filling medium releases the heat to the flowing water and achieves heating. In addition, the filling medium located in other areas is in a state of heat storage or no heat storage, waiting to exchange heat with the gas or water again. In this way, gas and water can be introduced at the same time for heat exchange without affecting each other, thus achieving the purpose of simultaneous heat storage and heat release. This makes it more convenient to use and provides better heat storage and heating effects.

[0037] It should be further noted that the technical features of the drive motor, reducer, etc. involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
