Description

Technical Field

[0001] The invention relates to the technical field of heat storage heating, and in particular to a solar chemical heat storage system for heating. Background Art

[0002] With the continuous development of the times, the technology of mutual conversion between solar energy and chemical energy has gradually entered every corner of society and is widely familiar to people. Among them, the application of heating system is the most common application field of solar energy and chemical energy storage conversion. However, the system devices commonly used in society for solar energy and chemical energy storage conversion have some disadvantages, and the emergence of these disadvantages has led to the traditional system devices for solar energy and chemical energy storage conversion being unable to meet the high-standard use needs of contemporary society. The disadvantages of the traditional system devices for solar energy and chemical energy storage conversion are now described as follows:

[0003] 1. During the use of traditional solar energy and chemical energy storage phase conversion system devices, the amount of solar energy absorption is often small, and the amount of solar energy absorption cannot be adjusted according to the use requirements of the heating system. In the current society, to address this problem, multiple solar energy and chemical energy storage phase conversion system devices are often used for superimposed absorption. However, this solution increases the loss of financial and material resources to a certain extent, and increases the subsequent maintenance and inspection work of professional maintenance personnel in this field.

[0004] Second, during the use of the traditional solar energy and chemical energy storage phase conversion system device, it often only generates heated water for use in the heating system, but cannot increase the generation of high-temperature steam to improve the ambient temperature according to the environmental requirements of the heating system.

[0005] 3. During the use of the traditional solar energy and chemical energy storage phase conversion system device, scale often appears during the hot water heating process, causing blockage inside the device, thereby shortening the service life of the device.

[0006] It can be seen that it is crucial for the art to propose a new solar chemical thermal storage system for heating to solve the above problems. Summary of the invention

[0007] In view of this, the purpose of the present invention is to provide a solar chemical thermal storage system for heating, so as to solve the problems of the conventional solar chemical energy storage applied to the heating system in the prior art, which is easy to generate scale and cannot generate high-temperature steam in a large scale, and further solves the problem that the conventional solar chemical energy storage applied to the heating system cannot adjust the amount of solar energy absorption according to the real-time situation.

[0008] The present invention is achieved through the following technical solutions:

[0009] A solar chemical heat storage system for heating, comprising an energy storage component for absorbing solar energy and adjusting the amount of solar energy absorbed, a storage battery for storing solar energy for chemical energy conversion, and a boiler body for outputting heat for heating;

[0010] The energy storage assembly includes a solar main board and solar sub-boards movably arranged on both sides of the solar main board, the solar sub-boards are rotatably stored at the bottom of the solar main board through fixing parts, and the solar sub-boards are rotatably supported on both sides of the solar main board through locking parts to form the same horizontal plane with the solar main board;

[0011] The solar mainboard is electrically connected to the battery via a power line, and the battery provides electrical energy to the boiler body via the power line;

[0012] The top of the boiler body is connected with a water inlet pipe and an exhaust pipe, and one side of the boiler body is connected with a water outlet pipe;

[0013] Also included is a softening component for softening the heating water and a regulating component for increasing the generation of high-temperature steam;

[0014] The softening assembly includes a funnel-shaped reaction tube connected to the water inlet pipe, a softening element for reacting and softening water, and a filter screen arranged inside the funnel-shaped reaction tube for accommodating the softening element. The funnel-shaped reaction tube is a hollow structure with openings on both sides, and the diameter of one opening is larger than the diameter of the other opening. The side with the smaller opening diameter of the funnel-shaped reaction tube is connected to the water inlet pipe. The changing space of the funnel-shaped reaction tube with gradually reduced diameter constitutes a pressurized space for water flow, thereby improving the water softening efficiency.

[0015] The adjustment components are provided in two groups and are symmetrically arranged on both sides of the boiler body. The adjustment components include a fan, a first electric push rod, an L-shaped baffle plate arranged on the output end of the first electric push rod, and a waterproof shell arranged on both sides of the boiler body. The waterproof shell is a hollow structure with one side open. The fan is arranged inside the waterproof shell. The waterproof shell is provided with a storage groove block that can accommodate the L-shaped baffle plate. The first electric push rod is extended to drive the L-shaped baffle plate to extend out of the storage groove block, and the interlaced area between the L-shaped baffle plate and the storage groove block can form a blocking surface for the opening of the waterproof shell.

[0016] Furthermore, the fixing member includes an elastic limit key arranged on one side of the solar sub-panel and a limit hole plate arranged on one side of the solar main board. The limit hole plate is provided with a limit hole engaged with the elastic limit key. The solar sub-panel is rotated until the elastic limit key is engaged with the inner side of the limit hole, so that the solar sub-panel is fixedly stored at the bottom of the solar main board.

[0017] Furthermore, the locking member includes a clamping block arranged on both sides of the solar main board through an elastic rope and a clamping hook arranged on both sides of the solar sub-panel through an elastic rope, the clamping block is provided with a clamping hole for the clamping hook to engage and lock, the solar sub-panel is rotated to be on the same horizontal plane as the solar main board and the clamping hook is engaged to the inner side of the clamping hole to form a supporting pulling force of the elastic rope on the solar sub-panel.

[0018] Furthermore, it also includes a self-protection component to prevent the boiler body from being damaged due to excessive gas pressure inside the boiler body.

[0019] Furthermore, the self-protection component includes an air pressure sensor arranged inside the boiler body, a pressure relief pipe connected to one side of the boiler body, and an electric valve arranged inside the pressure relief pipe.

[0020] Furthermore, the electric valve includes a second electric push rod obliquely arranged inside the pressure relief pipe and a telescopic door arranged inside the pressure relief pipe, and the air pressure sensor is connected to the microprocessor and the second electric push rod via a connecting line for signal transmission.

[0021] Furthermore, the telescopic door includes a telescopic sleeve arranged inside the pressure relief pipe through a hinge, a return spring arranged inside the telescopic sleeve and a telescopic plate connected to one end of the return spring, the telescopic sleeve is a hollow structure with one end open, and the telescopic plate can freely extend and retract inside the telescopic sleeve under the action of the elastic force of the return spring, and the top end of the telescopic sleeve is fixedly connected to the output end of the second electric push rod.

[0022] The beneficial effects of the present invention are:

[0023] 1. The solar chemical heat storage system for heating can effectively soften the water to be heated through the coordinated use of a funnel-type reaction tube, a softening element and a filter screen, so as to avoid scale generation during the heating process of the water and scale blockage inside the boiler body. Furthermore, a special funnel-type reaction tube design is adopted to soften the water flow in a pressurized space and increase the pressure of the water flow when it flows out of the water inlet pipe, thereby improving the softening efficiency of the heated water, so that the water flow can be softened as much as possible with the softening element.

[0024] 2. The solar chemical heat storage system for heating uses a solar main board, a solar sub-board, fixings and locking parts. When the solar energy absorption is too little to meet the heating environment demand, the locking parts can be used to support the solar sub-board so that it is on the same horizontal plane as the solar main board, thereby increasing the solar energy absorption rate. Compared with the traditional solar chemical energy storage heating system, there is no need to use a superimposed method for solar energy storage, which greatly reduces the output of financial and material resources.

[0025] 3. The solar chemical heat storage system for heating uses a fan, a first electric push rod, an L-shaped baffle and a waterproof shell. When the heating system needs to output a large amount of hot steam for heating, the first electric push rod can be shortened to drive the L-shaped baffle to move together, and the opening side of the waterproof shell is opened. At this time, the fan starts to work, and gas flow is formed on the surface of the hot water, thereby increasing the efficiency of generating hot steam.

[0026] In short, the technical solution of the present application solves the problem that traditional solar chemical energy storage is easily scaled and cannot generate high-temperature steam in large quantities when applied to heating systems through a coherent and compact structure. It further solves the problem that traditional solar chemical energy storage is unable to adjust the amount of solar energy absorption according to real-time conditions when applied to heating systems.

The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0040] See also Figure 1-6 , the present invention provides a technical solution: a solar chemical heat storage system for heating, comprising an energy storage component 1 for absorbing solar energy and adjusting the amount of solar energy absorbed, a storage battery 4 for storing solar energy for chemical energy conversion, and a boiler body 8 for outputting heat for heating;

[0041] The energy storage assembly 1 includes a solar main board 101 and solar sub-boards 102 movably arranged on both sides of the solar main board 101. The solar sub-boards 102 are rotated and stored at the bottom of the solar main board 101 through the fixing member 2. The solar sub-boards 102 are rotated and supported on both sides of the solar main board 101 through the locking member 3 to form the same horizontal plane with the solar main board 101. When there is no need to increase the amount of solar energy absorbed, only the solar main board 101 can work. The solar sub-boards 102 are stored at the bottom of the solar main board 101. When it is necessary to increase the amount of solar energy absorbed, the locking member 3 is used to make the solar sub-board and the solar main board horizontal to absorb solar energy.

[0042] The solar mainboard 101 is electrically connected to the battery 4 through a power line, and the battery 4 provides electric energy to the boiler body 8 through the power line. The absorbed solar energy is converted into electric energy and stored in the battery 4.

[0043] The top of the boiler body 8 is connected with a water inlet pipe 5 and an exhaust pipe 6, and one side of the boiler body 8 is connected with a water outlet pipe 13, and the boiler body is injected with water to be heated through the water inlet pipe;

[0044] It also includes a softening component 7 for softening the heating water and a regulating component 9 for increasing the generation of high-temperature steam;

[0045] The softening assembly 7 includes a funnel-shaped reaction tube 701 connected to the water inlet pipe 5, a softening component 703 for reacting and softening water, and a filter 702 arranged inside the funnel-shaped reaction tube 701 for accommodating the softening component 703. The funnel-shaped reaction tube 701 is a hollow structure with openings on both sides, and the diameter of one opening is larger than the diameter of the other opening. The side with a smaller opening diameter of the funnel-shaped reaction tube 701 is connected to the water inlet pipe. The changing space of the funnel-shaped reaction tube 701 with a gradually reduced diameter constitutes a pressurized space for water flow, thereby improving the water softening efficiency. It should be emphasized here that the softening components are zeolite and ion exchangers. When the flowing water flows through the drainage pipe, the zeolite and ion exchangers react with the flowing water, thereby effectively softening the flowing water to avoid the generation of scale when the flowing water flows to the inside of the heat storage shell for heating, which causes blockage inside the device. The funnel-shaped reaction tube is specially set to a design with different opening diameters. For further reference, please refer to the attached manual. Figure 6 The purpose is that when the water flows into the funnel-shaped reaction tube, it can play a certain compression and pressurization process, thereby increasing the pressure of the water when it flows out, avoiding the phenomenon of water pipe blockage. In addition, by pressurizing the water flow and performing a softening reaction, the softening efficiency can be improved, so as to increase the contact rate between the flowing water and the reaction piece;

[0046] There are two groups of adjustment components 9, which are symmetrically arranged on both sides of the boiler body 8. The adjustment components 9 include a fan 902, a first electric push rod 903, an L-shaped baffle 901 arranged on the output end of the first electric push rod, and a waterproof shell 904 arranged on both sides of the boiler body 8. The waterproof shell is a hollow structure with an opening on one side. The fan is arranged inside the waterproof shell. The waterproof shell is provided with a storage slot block that can accommodate the L-shaped baffle. The first electric push rod is extended to drive the L-shaped baffle to extend out of the storage slot block, and the interlaced area between the L-shaped baffle and the storage slot block can form a blocking surface for the opening of the waterproof shell. The model of the first electric push rod and the second electric push rod mentioned in the present application can be JU-TGE electric push rod. When the boiler body is in the opposite When the hot water is heated to generate hot steam, the first electric push rod can begin to shrink and drive the L-shaped baffle to move until the L-shaped baffle is shrunk to the inside of the storage slot block, so that the opening on one side of the waterproof shell is opened. At this time, the fan starts to work, forming a gas flow on the surface of the hot water, thereby effectively accelerating the generation of hot steam, thereby satisfying the function of efficiently generating hot steam for use by the heating system. When there is no need to speed up the steam output, the first electric push rod is extended, and the L-shaped baffle is pulled out of the storage slot block to form a blockage for the opening of the waterproof shell. At this time, the fan stops working. It should be emphasized here that the generated hot steam is discharged through the exhaust pipe, and the heated hot water is discharged through the water outlet pipe for use in the heating system environment.

[0047] In the present invention, the fixing member 2 includes an elastic limit key 201 arranged on one side of the solar sub-panel 102 and a limit hole plate 202 arranged on one side of the solar main board. The limit hole plate is provided with a limit hole engaged with the elastic limit key. The solar sub-panel rotates until the elastic limit key is engaged with the inner side of the limit hole to form the solar sub-panel fixedly stored at the bottom of the solar main board. When the solar sub-panel needs to be fixed to the bottom of the solar main board, the elastic limit key can be engaged with the inner side of the limit hole to form the solar sub-panel fixed to the solar main board. Bottom, when the solar sub-panel needs to be separated from the bottom of the solar main board, it is only necessary to press the elastic limit key to make it shrink inward and gradually separate from the inner side of the limit hole, so that the solar main board can be separated from the solar sub-panel. It should be emphasized here that the elastic limit key mentioned in the present application has been disclosed in the authorized and disclosed utility model case "A device for building construction simulation based on BIM" (CN208281424U), and the structural principle of the elastic limit key has been disclosed, so this application will not repeat it.

[0048] In the present invention, the locking member 3 includes a clamping block 301 arranged on both sides of the solar main board through an elastic rope and a clamping hook 302 arranged on both sides of the solar sub-panel through an elastic rope. A clamping hole for the clamping hook to be engaged and locked is opened on the clamping block. The solar sub-panel rotates to be on the same horizontal plane with the solar main board and the clamping hook is engaged to the inner side of the clamping hole to form a supporting tension of the elastic rope on the solar sub-panel. When it is necessary to increase the collection of solar energy, after the solar main board is separated from the solar sub-panel, the clamping hook can be inserted into the inner side of the clamping hole, and the elastic rope is used to support the solar sub-panel, so that the solar main board and the solar sub-panel are on the same horizontal plane and receive solar energy together.

[0049] The present invention also includes a self-protection component 10 for preventing the boiler body 8 from being damaged due to excessive gas pressure inside the boiler body 8.

[0050] In the present invention: the self-protection component 10 includes an air pressure sensor 1001 arranged inside the boiler body 8, a pressure relief pipe 1002 connected to one side of the boiler body and an electric valve 11 arranged inside the pressure relief pipe. The model of the air pressure sensor can be a MIK-P300 air pressure sensor. When the air pressure sensor detects that the air pressure inside the boiler body is too high, the electric valve can be used to allow the pressure relief pipe to discharge gas smoothly to reduce the gas pressure inside the boiler body.

[0051] In the present invention: the electric valve 11 includes a second electric push rod 1101 obliquely arranged inside the pressure relief pipe and a telescopic door 12 arranged inside the pressure relief pipe. The air pressure sensor is connected to the microprocessor and the second electric push rod through a connecting line to transmit signals. The telescopic door is opened or closed by the extension and retraction of the second electric push rod to control the closure or unobstructed state of the pressure relief pipe. It should be emphasized here that when the air pressure sensor captures that the gas pressure inside the boiler body is too high, the microprocessor sends an instruction command to the second electric push rod, and the second electric push rod automatically contracts.

[0052] In the present invention: the telescopic door 12 includes a telescopic sleeve 1202 arranged inside the pressure relief pipe through a hinge, a return spring 1201 arranged inside the telescopic sleeve and a telescopic plate 1203 connected to one end of the return spring. The telescopic sleeve is a hollow structure with an opening at one end. The telescopic plate can freely extend and retract inside the telescopic sleeve under the action of the elastic force of the return spring. The top end of the telescopic sleeve is fixedly connected to the output end of the second electric push rod. When the second electric push rod is extended, the telescopic sleeve can be perpendicular to the pressure relief pipe. At the same time, the telescopic plate is arranged inside the telescopic sleeve in a telescopic and adjustable manner using the return spring. The purpose is to avoid the telescopic plate from getting stuck during the extension and retraction of the telescopic sleeve. When the second electric push rod is shortened, the telescopic sleeve is in a dumping state, so that the telescopic plate extends together under the elastic force of the return spring. At this time, the telescopic sleeve and the telescopic plate do not form a sealing work for the opening of the pressure relief pipe, and the gas inside the boiler body can be discharged smoothly through the pressure relief pipe to reduce the gas pressure inside the boiler body.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
