The existing black ceramic composite ceramic solar panel is made by using common ceramic raw materials to prepare pug through conventional treatment, and is formed by vacuum slip casting through a gypsum mould, wherein four sides are generally closed, collecting channels are arranged at two longitudinal opposite sides, and porous through hole plates with water inlets and water outlets are arranged at opposite angles. Then mixing a ceramic black coloring agent with a common ceramic raw material to prepare slurry, covering the black slurry on the surface of a ceramic hollow plate biscuit, drying and sintering to obtain the black ceramic solar plate with the substrate being common ceramic and the surface being a black ceramic layer. Because each fluid channel of the solar panel is parallel to the panel body and is arranged in parallel, only one fluid inlet is provided, and the fluid has a certain speed in the circulating heating process, the uniform flow of the fluid through each channel of the black ceramic solar panel is difficult to realize, the flow velocity of the fluid in each channel is not completely the same, and the utilization rate of heat absorption of the black ceramic solar panel is reduced. In addition, in order to ensure the utilization rate of the absorbed heat of the black porcelain solar panel, the heat loss of the fluid flowing through the black porcelain solar panel needs to be reduced, namely, the black porcelain solar panel needs to be insulated. The traditional heat preservation mode is to set up the heat preservation at the back of black porcelain solar panel, but the life of heat preservation material is limited, can reduce the life of black porcelain solar panel.

The solar heat storage system can be divided into short-term energy storage and cross-season long-term energy storage according to different storage time, wherein the cross-season long-term energy storage is used for storing solar heat in summer for a long period in a cross-season mode and then supplying the solar heat to winter heating, so that the limitation that solar heat utilization is affected by seasonality is reduced. The inventor finds that although the solar cross-season heat storage technology is widely regarded for remarkable energy saving effect in recent years, heat loss is still a great problem faced by the solar cross-season energy storage technology, and the long-period cross-season heat storage performance of solar energy is seriously influenced by the heat loss. Furthermore, the energy storage system is generally arranged underground, and when the heat in the energy storage system is dissipated to the surrounding environment, the surrounding environment is adversely affected.

Detailed Description

It is to be understood that the following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the invention. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

and two ends of the heat preservation cavity are plugged.

In some embodiments, a first seal head and a second seal head are respectively arranged at two ends of the black porcelain solar panel, the first seal head is provided with an inlet, and the second seal head is provided with an outlet;

the baffle is arranged in the first seal head, the baffle is arranged at the downstream of the inlet, and the baffle is vertical to the flowing direction of the fluid.

Circulating water enters the seal head at a certain speed under the action of the pump, if the circulating water is not optimized, the pressure distribution of the circulating water in the seal head is uneven, the flow rate of the circulating water in the fluid channel close to the inlet under the impact action of the water is large, the flow rate of the circulating water in the fluid channel at the edge is small, the absorption efficiency of the circulating water on heat converted by the black porcelain solar panel is further influenced, on one hand, the photo-thermal conversion efficiency of the black porcelain solar panel is reduced, on the other hand, the temperature of the sun-facing surface of the black porcelain solar panel is uneven, and the service life of the black porcelain solar panel is further influenced.

The downstream of the inlet of the first seal head is provided with a baffle which is vertical to the flowing direction of the fluid, and circulating water flowing into the first seal head from the inlet at a certain speed can flow to the two sides of the baffle under the blocking effect of the baffle, and then enters each fluid channel through being full of the seal head. The baffle can block the impact of rivers to a certain extent, and then at the average circulating water of a certain extent, improves the homogeneity that the circulating water distributes in fluid passage.

Furthermore, the inner side surface of the first seal head is provided with an expanding and decompressing section and a flow guiding and pressurizing section, one end of the expanding and decompressing section, which comprises a first inclined surface and a second inclined surface which are distributed on two sides of the inlet, is connected with the inlet, and the other end of the expanding and decompressing section inclines towards the outside; the joints of the first inclined surface and the second inclined surface with the inlet are in smooth transition;

the flow guide pressurizing section comprises a first cambered surface and a second cambered surface, and the first cambered surface and the second cambered surface are connected between the expanding and depressurizing section and the heat preservation chamber.

Tests show that if the inlet is directly cylindrical or the inlet is directly communicated with the space suddenly enlarged, the sprayed water flow exists in a water column form, and under the condition, the uniformity and the stability of the water pressure of the water flow in the end socket can be seriously influenced, so that the distribution uniformity of circulating water in a fluid channel is influenced.

When the inner side of the inlet is connected with the expanding section, the water flow can be stably expanded and decompressed due to the drainage dispersion effect of the expanding section, so that the condition that the water pressure inside the end socket is not uniformly distributed is relieved.

Due to the cooperation of the expanding and decompressing section and the baffle, circulating water can be distributed into each fluid channel after filling the seal head more gently.

Because the water flow far away from the inlet is small, the water pressure is small, the arc-shaped flow guide pressurizing section is arranged to limit the cross section area of the water flow channel, so that the water flow is pressurized, the water flow smoothly flows into the fluid channel at the edge, and the flowing speed in the fluid channel is ensured.

Furthermore, the distance between the inlet and the baffle is marked as A, the distance between the end part of the black porcelain solar panel body and the baffle is B, A: b is 1: 1-2.

Tests show that if the ratio of the two distances is too large, the baffle plate can have a certain blocking effect on the water flow flowing into the fluid channel, and if the ratio of the two distances is too small, the buffering effect of the water flow at the inlet can be influenced. The value A can be 5cm, 10cm, 15cm, 20cm, 25cm and the like, and is determined according to the size and the specific application environment of the black porcelain solar panel.

In some embodiments, the insulating chamber is filled with a foamed insulating material. The foaming heat-insulating material cooperates with the air, can improve the heat preservation effect of heat preservation cavity, even along with the extension of live time, foaming heat-insulating material became invalid, and the air bed in the heat preservation cavity still can gain better heat preservation effect.

The heat preservation chamber can be a single chamber or a plurality of chambers arranged in parallel.

In some embodiments, the black ceramic solar panel is arranged obliquely, and the outlet end is positioned above the inlet end.

Furthermore, a water storage tank is arranged on a connecting pipeline between the outlet of the cross-season energy storage device and the inlet of the black porcelain solar panel, and a pump is arranged at the outlet end of the water storage tank.

The black porcelain solar panel is obliquely arranged, the outlet end is positioned above, and the inlet end is positioned below, so that circulating water enters from the lower part and flows out from the upper part. Under the arrangement mode, the black porcelain solar panel can be ensured to be in a completely full state during working so as to ensure the working efficiency of the black porcelain solar panel. After summer, the pump can be stopped, water in the black porcelain solar panel can flow out from the inlet and directly flows into the water storage tank, water can be effectively prevented from being stored in the black porcelain solar panel, and the black porcelain solar panel is damaged due to freezing and expansion of the water in winter. The design of the diversion pressurizing section and the diameter expanding depressurizing section in the first seal head enables the inlet to be located at the lowest position, so that water in the black porcelain solar panel can be conveniently and completely discharged.

In some embodiments, the cross-season energy storage system comprises an energy storage cavity, an energy absorption medium filled in the energy storage cavity, and a heat exchange pipeline arranged in the energy storage cavity, wherein an inlet end of the heat exchange pipeline is communicated with an outlet of the black porcelain solar panel, and an outlet end of the heat exchange pipeline is communicated with an inlet of the black porcelain solar panel.

Furthermore, the energy storage cavity is concentric annular cavity, is formed by a plurality of concentric barrels in a separated mode, and each barrel comprises a supporting layer and a heat preservation layer, and the heat preservation layer is attached to the supporting layer.

Furthermore, the number of the annular chambers in the concentric annular chambers is 2-5.

Set up the energy storage chamber to concentric ring-type, at the energy storage in-process, outer energy storage chamber all can be for the heat preservation in inboard energy storage chamber, because the coefficient of heat conductivity of energy storage media such as soil is less, and outer soil has higher temperature under the heat preservation effect of heat preservation, so can have better energy storage effect to prevent the thermal loss of inlayer better.

Furthermore, the inlet end of the heat exchange pipeline is positioned in the outermost annular chamber, and the outlet end of the heat exchange pipeline is positioned in the innermost annular chamber.

Furthermore, the circulating water flows along the heat exchange pipeline for a circle along the outermost annular chamber, then enters the inner annular chamber for a circle, and finally enters the innermost annular chamber.

Still further, the heat exchange pipeline is a coiled pipe, and the coiled pipe is vertically arranged.

The heat exchange pipeline is a coiled pipe and is arranged along the circumferential direction of the annular cavity, so that the filled energy storage medium can be fully heated, and when heat is released, the heat can be fully released, and the full utilization of the stored heat is improved.

The vertical setting of coiled pipe can carry out the heat transfer on the whole direction of height of energy storage medium to improve thermal utilization ratio.

Circulating water flows through the outer periphery and then flows on the inner periphery in sequence, the temperature of the flowing area of the circulating water is increased in sequence, heat of a low-temperature area can be recovered better by utilizing the temperature difference, the circulating water can obtain higher temperature under the heating action of a high-temperature area, and the circulating water can be used better in the follow-up process.

Further, the heat exchange pipeline is provided with fins. The fins improve the heat exchange area and further improve the heat exchange efficiency.

Further, the number of the annular chambers is 3.

Further, the radial width of the innermost annular chamber is the largest and the radial width of the outermost annular chamber is the smallest. The volume of the energy storage medium in the innermost layer is maximized, and heat can be stored better.

In some embodiments, the concentric annular chambers are layered with the bottom of the outermost annular chamber being the lowest and the bottom of the innermost annular chamber being the highest.

When the energy storage medium is soil, the bottom layer of the concentric annular chambers can be arranged due to a certain supporting effect of the soil, so that the energy storage medium in the inner layer can be better insulated, and the heat loss of the inner layer can be reduced less.

Furthermore, a supporting device is arranged between the bottoms of the adjacent concentric annular chambers.

The supporting device can be a supporting column or a supporting pier and other structures, and energy storage media such as soil or water can be filled between the bottoms of the adjacent concentric annular chambers or the energy storage media can not be filled.

Furthermore, the support means are distributed at least in the peripheral and middle regions of the bottom of the annular chamber. And better support for the energy storage system.

In some embodiments, the concentric annular chambers are covered with insulation above.

Furthermore, the shell material of heat preservation is the steel, and steel shell structure skin cladding plastic layer.

Because the energy storage system is located underground and has a large volume, the top of the energy storage system needs to be covered with a soil layer, and the land above the energy storage system can be used for normal production activities or building buildings, the heat insulation layer needs to have certain strength to prevent the energy storage system from being crushed. The steel material has higher strength, and can have stronger compressive strength under the supporting action of an energy storage system, soil and the like, but the steel has good heat conductivity and is not corrosion-resistant. The periphery of the steel shell is coated with the plastic layer to improve the heat insulation performance of the steel shell, and meanwhile, the steel is isolated from water, so that corrosion is avoided.

Furthermore, a cavity is arranged in the shell, and a heat preservation medium is filled in the cavity. The heat preservation medium can be a foaming material and the like.

The heat preservation medium is positioned in the shell and is protected by the shell, so that the service life of the shell can be prolonged well.

In a similar way, the heat-insulating layer on the concentric cylinder body of the energy storage cavity is also of a structure that heat-insulating materials are filled in the shell. So as to better prolong the service life of the heat-insulating layer of the energy storage cavity.

Furthermore, a plurality of heat preservation cavities arranged in parallel are arranged in the shell of the heat preservation layer.

The shell of the heat-insulating layer is divided into a plurality of heat-insulating chambers, and the side wall of each heat-insulating chamber can support the heat-insulating layer to a certain extent, so that the overall rigidity of the heat-insulating layer is further improved, and deformation under the action of pressure is prevented.

In some embodiments, a filter is arranged on a connecting pipeline between the black porcelain solar panel and the cross-season energy storage system. The circulating water is filtered, so that the influence on heat exchange pipelines in the seasonal energy storage system is reduced as much as possible, and the service life of the heat exchange pipelines is prolonged.

In some embodiments, the warmed circulating water first flows through the outermost peripheral chamber of the concentric annular chambers of the cross-season energy storage system, then flows through the middle chamber of the concentric annular chambers, finally flows through the innermost chamber, and then flows out of the cross-season energy storage system from the innermost chamber.

In some embodiments, a driving force is provided for the flow of the circulating water by the pump, when the energy storage is finished, the pump stops running, and the circulating water in the pipeline falls into the water storage tank under the action of self gravity to empty the black porcelain solar panel.

The black porcelain solar panel is prevented from being full of water and being frozen and cracked in winter.
