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.

[0037] The purpose of this invention is to provide an energy storage, heat storage, and heat recovery equipment for distilling alcohol, in order to solve the problems existing in the prior art, reduce the cost of steam production, and make it suitable for widespread use.

[0038] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] like Figures 1-2 As shown, this embodiment provides an energy storage, heat storage, and heat recovery distillation equipment, mainly including a distillation system 200 and a heat storage device 100. The distillation system 200 mainly includes a distillation still 201 and a condenser 204. The distillation still 201 is equipped with a grate for supporting solid mash. A steam supply device is also provided inside the distillation still 201, located below the grate, for introducing steam. The steam can pass upwards through the grate and then evenly through the mash. The layers rise, generating alcohol vapor; the top of the still 201 is connected to the condenser 204 via an alcohol vapor discharge pipe 202. The condenser 204 can condense the alcohol vapor into liquid alcohol, which is then discharged through the liquid alcohol outlet 205. The condenser 204 is also equipped with a cold water inlet and a hot water outlet. The cold water inlet is used to introduce cold water to cool the alcohol vapor, and the hot water generated after the cold water absorbs heat is discharged through the hot water outlet. This is a mature technology in the field and will not be described in detail in this embodiment.

[0041] The heat storage device 100 includes a heat storage material, a heating element, and a heat exchange assembly. The heating element is disposed within the heat storage material and is used to heat the heat storage material. The heat exchange assembly includes an inlet medium chamber 107, heat exchange tubes 108, and an outlet medium chamber 110. The inlet medium chamber 107 and the outlet medium chamber 110 are respectively disposed on the bottom and top sides of the heat storage material. The inlet medium chamber 107 is connected to a medium inlet pipe 103 for introducing the heat exchange medium. Multiple heat exchange tubes 108 are provided. The bottom of any one heat exchange tube 108 is connected to the inlet medium chamber 107, and the top of any one of them is connected to the outlet medium chamber 110. The outlet medium chamber 110 is connected to the steam supply device through a medium outlet pipe 111, which can introduce the heated heat exchange medium into the steam supply device, thereby providing steam to the still 201.

[0042] In this embodiment, off-peak electricity or green electricity is used to heat the heat storage material through a heating element, which can store the heat energy in the heat storage material. Then, the heat exchange medium is added into the medium inlet chamber 107 through the medium inlet pipe 103, and then enters the heat exchange tube 108 to absorb the heat energy of the heat storage material. After absorbing heat, the heat exchange medium enters the medium outlet chamber 110 and is transported to the steam supply device through the medium outlet pipe 111 to provide steam for the distillation system 200. In this embodiment, the heat storage device 100 can make full use of off-peak electricity or green electricity, reducing the production cost of steam.

[0043] In this embodiment, the heat storage material is preferably a solid heat storage material, which is a single unit cast from heat storage material. Heating channels are provided within the solid heat storage material, and heating elements are disposed within these channels. Multiple heating channels are evenly distributed, and each heating channel penetrates the solid heat storage material horizontally. Each heating channel contains a heating element. Through the evenly distributed multiple heating channels and their respective heating elements, different locations within the solid heat storage material can be heated, thereby achieving comprehensive heating of the solid heat storage material and improving the heating effect.

[0044] In a preferred embodiment, the multiple heating channels can be arranged in an array, for example, in a rectangular array with a spacing of 20 mm between adjacent heating channels, or in a circular array, or in other arrangements, such as the multiple heating channels being arranged in a crisscross pattern, or in a surrounding or spiral arrangement.

[0045] In this embodiment, the heating element is preferably a resistance heating element, such as a resistance heating wire, which can extend into the heating channel to heat the solid heat storage material. The resistance heating wire is preferably a spiral heating wire to improve the heating effect. The heating element can be connected to mains power to utilize off-peak electricity for heating, reducing electricity costs. Alternatively, the heating element can be directly connected to wind power generation devices and solar power generation devices without the need for an inverter, utilizing wind or solar power for power generation. It should be noted that the wind power generation devices and solar power generation devices are mature existing technologies in the art, and will not be described in detail in this embodiment.

[0046] In this embodiment, the heating element is preferably connected in a three-phase star configuration. With this configuration, when the three-phase load is perfectly symmetrical (all heating elements have the same resistance), the neutral current is zero, ensuring balanced three-phase current and preventing excess current from returning to the grid. When using off-peak electricity for heating, the balanced load prevents three-phase imbalance in the grid, avoiding additional line losses, reduced transformer efficiency, and adverse effects on other electrical equipment caused by imbalance, thus meeting the requirements of the power grid company. When using wind power, the three-phase wind turbine itself outputs three-phase electricity. Connecting it to a balanced three-phase load can make the three-phase wind turbine run more smoothly, reducing vibration and torque fluctuations, and improving power generation efficiency and equipment lifespan. Solar power generation devices also benefit from balanced loads.

[0047] Moreover, the standard industrial three-phase voltage (line voltage) is 380V. When a three-phase power supply is connected in a star configuration, the actual voltage that each heating element bears is the phase voltage of 220V (380V / √3≈220V). This allows the rated voltage of a single heating element to be designed to the common 220V level, making it easy to manufacture, technologically mature, and cost-effective.

[0048] Alternatively, the heating element can be connected in other ways as needed, such as a delta connection.

[0049] In this embodiment, the outer wall of the heat exchange tube 108 is also coated with a high-temperature release agent. When the solid heat storage material is heated by the heating element, the solid heat storage material and the heat exchange tube 108 inside it expand due to the heat. Since the expansion coefficients of the solid heat storage material and the heat exchange tube 108 are different, the heat exchange tube 108 will move relative to the solid heat storage material. Therefore, coating the outer wall of the heat exchange tube 108 with a high-temperature release agent reduces the coefficient of friction between the heat exchange tube 108 and the solid heat storage material, facilitating relative sliding and preventing damage to the heat exchange tube 108 or cracking of the solid heat storage material due to a large coefficient of friction. The heat exchange tube 108 can be a metal tube, such as a stainless steel tube, and the high-temperature release agent can be a powder release agent such as graphite powder or mica powder, or other release agents.

[0050] In this embodiment, the heat exchange tube 108 is preferably an S-shaped curved tube, which is formed by connecting multiple S-shaped tubes sequentially from bottom to top, thereby increasing the travel distance of the heat exchange medium within the heat storage material and improving the heat exchange effect. Furthermore, the heat exchange tube 108 can also be a finned tube, that is, heat exchange fins are also sleeved on the outer side of the heat exchange tube 108 (on the outer side of each straight segment when it is an S-shaped curved tube), increasing the heat exchange area and improving the heat exchange effect. The heat exchange fins are only sleeved on the outer side of the heat exchange tube 108 and are not fixed to the heat exchange tube 108, or only at both ends are fixed to the heat exchange tube 108, so that when the heat exchange tube 108 expands, it can detach from the heat exchange fins to facilitate sliding relative to the heat storage material.

[0051] In this embodiment, the heat exchange medium can be water (pure water). The medium inlet chamber 107 is connected to a water storage tank 102 through the medium inlet pipe 103 for introducing water. A water pump 104 can be installed on the medium inlet pipe 103. The steam supply device includes a steam supply pipe 203. The medium outlet chamber 110 is connected to the steam supply pipe 203 through the medium outlet pipe 111, which can introduce the steam generated after heating the water into the still pot through the steam supply pipe 203.

[0052] The gas supply pipe 203 is preferably a disc-shaped pipe, and the disc-shaped pipe has multiple gas outlet holes 2031 evenly distributed on it, which can realize the uniform steam output and ensure the distillation effect.

[0053] Furthermore, the water storage tank 102 is also connected to the hot water outlet of the condenser 204 via a hot water return pipe 207, so that the hot water generated by the condenser 204 can flow back into the water storage tank 102, thereby achieving full recovery and utilization of heat.

[0054] In this embodiment, the medium inlet chamber 107 is also provided with a drain outlet, which is connected to the water storage tank 102 through a drain pipe 105. A drain pump 106 is also provided on the drain pipe 105. When the output water vapor meets the usage requirements and no more water vapor is needed, the water inlet is stopped, the drain outlet is opened, and the high-temperature water is discharged into the water storage tank 102. This can recover and utilize the waste heat of the high-temperature water, and can prevent the high-temperature water in the heat exchange tube 108 from continuing to absorb heat and vaporize, which would cause the pressure in the heat exchange tube 108 to be too high, resulting in the destruction of the heat exchange tube 108 and the solid heat storage material.

[0055] In this embodiment, a control valve is also provided on the medium outlet pipe 111 to facilitate control of the switch. The control valve is preferably an electrically controlled valve, which can be electrically controlled to prevent burns when manually switching on and off. Furthermore, electrically controlled valves can also be provided on the medium inlet pipe 103 and the drain pipe 105. The electrically controlled valve is connected to the intelligent controller via a signal, and the switch is controlled by the intelligent controller. The intelligent controller can be selected according to specific working needs, and is preferably a PLC controller.

[0056] In this embodiment, the cold water inlet of the condenser 204 is connected to a cold water inlet pipe 206, which is connected to the hot water return pipe 207 via a heat exchange device 208 to achieve heat exchange. Specifically, the hot water in the hot water return pipe 207 can absorb the heat from the room temperature water flowing into the cold water inlet pipe 206 through the heat exchange device 208, thereby achieving heat recovery and utilization, and can also lower the water temperature in the cold water inlet pipe 206 to cool the alcohol vapor.

[0057] The heat exchange device 208 can be selected according to specific working needs; for example, a plate heat exchanger can be selected.

[0058] Alternatively, the heat exchange medium can also be a gas (such as sterile air). The medium inlet chamber 107 is connected to a gas supply device via the medium inlet pipe 103 for introducing gas. The steam supply device includes a gas supply pipe 203, and the bottom of the still 201 can hold water, with the gas supply pipe 203 submerged in the water. The medium outlet chamber 110 is connected to the gas supply pipe 203 via the medium outlet pipe 111, allowing heated gas to be introduced into the still 201 through the gas supply pipe 203 to heat the water in the still 201 and generate steam. The gas supply device can be selected according to specific operational needs, for example, it can be an air pump or a gas cylinder.

[0059] In this embodiment, the heat storage material includes basalt particles, quartz sand, kaolinite particles, magnesium oxide particles, and a binder. The weight ratio of the basalt particles, quartz sand, kaolinite particles, magnesium oxide particles, and the binder is 70-80% : 1-4% : 3-4% : 8-10% : 10-12%. The binder can be selected according to specific working needs, and is preferably refractory cement. Among them, basalt particles account for the largest proportion of the main material (70-80%). They have high specific heat capacity and thermal stability, and can maintain structural stability for a long time at high temperatures. They are excellent heat storage carriers and have low cost. Magnesium oxide particles (8-10%) also have high melting point and heat capacity, which further enhances the overall heat storage capacity. Quartz sand (1-4%) and kaolinite particles (3-4%) can moderately improve the thermal conductivity of the material, promote the uniform transfer of heat inside the heat storage material, and avoid local overheating or excessive thermal resistance. The binder (10-12%, such as refractory cement) ensures that the material has sufficient mechanical strength and structural integrity after casting and molding, and prevents cracking or pulverization at high temperatures.

[0060] In this embodiment, basalt particles, quartz sand, kaolinite particles, magnesium oxide particles, and refractory cement are used as the main raw materials. These materials have high specific heat capacity and low cost, which can reduce the overall cost while ensuring the heat storage effect. Moreover, the above-mentioned heat storage materials have high melting points and can withstand high heating temperatures to heat the water in the heat exchange tube 108. In this embodiment, the heat storage material is cast into a solid heat storage material, and the heat exchange tube 108 is cast into the solid heat storage material, which can ensure sufficient contact and improve the heat exchange effect.

[0061] Alternatively, other materials with high specific heat capacity and low cost can be selected as heat storage materials as needed.

[0062] In this embodiment, an outer shell 101 is also included. The outer shell 101 is wrapped around the outside of the heat storage material. The outer shell 101 can protect the heat storage material, and even if the solid heat storage material breaks, the presence of the outer shell 101 can prevent the solid heat storage material from scattering, so that it can still work normally. Moreover, the outer shell 101 can also be used as a template during casting.

[0063] Furthermore, the outer side of the outer shell 101 is also wrapped with an insulation layer for heat preservation and to reduce heat loss; wherein, the insulation layer can be selected according to specific working needs, for example, it can be ceramic fiber cotton or rock wool board, etc.

[0064] Example 2

[0065] This embodiment is a modification based on Embodiment 1, and its main difference from Embodiment 1 is:

[0066] In this embodiment, the heat storage material is a granular heat storage material. In this case, an outer shell 101 must be provided, and the granular heat storage material is filled inside the outer shell 101. A heating tube 109 is also provided inside the granular heat storage material, and the heating element is disposed inside the heating tube 109. The heating tube 109 can effectively protect the heating element while ensuring heating. The heating tube 109 can be a non-metallic tube such as a ceramic tube.

[0067] The heating tubes 109 are evenly distributed in multiple locations, and each heating tube 109 penetrates the granular heat storage material in a horizontal direction. Each heating tube 109 is equipped with a heating element. Through the evenly distributed multiple heating tubes 109 and the heating elements inside them, different positions of the granular heat storage material can be heated, thereby achieving comprehensive heating of the granular heat storage material and improving the heating effect.

[0068] In a preferred embodiment, the multiple heating tubes 109 can be arranged in an array, for example, in a rectangular array, or in a circular array, or other arrangements can be selected, such as the multiple heating tubes 109 being arranged in a crisscross pattern, or in a surrounding or spiral arrangement.

[0069] In this embodiment, the particulate thermal storage material may include basalt particles, quartz sand, kaolinite particles, and magnesium oxide particles, etc.

[0070] In this embodiment, the outer shell 101 is further provided with multiple vertical partitions from front to back. The vertical partitions are perpendicular to the length direction of the outer shell 101, and the vertical partitions are provided with multiple material passage holes to allow the granular heat storage material to pass through.

[0071] The adjacent vertical partitions, the frontmost vertical partition and the front end plate of the outer shell 101, and the rearmost vertical partition and the rear end plate of the outer shell 101 are all connected by multiple tie rods, which can form a stable internal skeleton structure, prevent the vertical partitions from tilting, deforming or shifting, and prevent the internal materials from squeezing the outer shell 101, causing it to deform or even crack.

[0072] In this embodiment, a circulating air system is also included. The circulating air system includes a circulating fan, a ventilation box, and an air outlet pipe. The ventilation box is located inside the outer shell 101. An air inlet is provided on one side for air intake, and the other side is connected to the air outlet pipe.
