If the heat exchange medium is one or two, three passages or two passages can be selected to flow into the same heat exchange medium according to the flow requirement. When the temperature of the heat exchange medium is higher than that of the heat storage assembly, the heat storage assembly absorbs heat and stores heat; when the temperature of the heat exchange medium is lower than that of the heat storage assembly, the heat storage assembly releases heat to enable the heat exchange medium to be heated.
As shown in fig. 1, in some embodiments, two parallel side plates 2 are disposed between two first hole plates 303 and outside the heat storage assembly 4, and the two first hole plates 303 and the two side plates 2 form a box body with two open ends; and a fourth heat exchange medium circulation passage 12 which is vertically arranged is formed in the space inside the box body and outside the heat storage assembly 4.

In some embodiments, as shown in fig. 2, a second tube 7 is disposed at the two open ends of the box body, and a first tube 6 is disposed outside each of the two third pore plates 301; the first pipe body 6 and the second pipe body 7 are conical square pipes, the circumference of a first port of each square pipe is larger than that of a second port of each square pipe, and the first port of each square pipe is connected with the side plate 2.

When the heat storage component 4 is a phase-change or liquid heat storage material with a metal shell, the heat exchange medium is gas or liquid.
The utility model relates to a using method of a multi-channel heat storage device, which comprises the following steps:
when the heat exchange medium is dust-free gas or liquid, the heat exchange medium can flow through the first heat exchange medium circulation passage 9, the second heat exchange medium circulation passage 10, the third heat exchange medium circulation passage 11, and/or the fourth heat exchange medium circulation passage 12, and heat storage or heat release is completed in the circulation process of the heat exchange medium. When the temperature of the heat exchange medium is higher than that of the heat storage assembly, the heat storage assembly absorbs heat and stores heat; when the temperature of the heat exchange medium is lower than that of the heat storage assembly, the heat storage assembly releases heat to enable the heat exchange medium to be heated. The circulation passages of the three heat exchange media are mutually independent, and when the three media exchange heat, the three media can respectively enter the heat storage device through the three passages. If the heat exchange medium is one or two, three passages or two passages can be selected to flow into the same heat exchange medium according to the flow requirement.
When the heat exchange medium is the dust-containing flue gas, the heat exchange medium flows through the fourth heat exchange medium circulation passage 12, and heat storage or heat release is completed in the circulation process of the heat exchange medium. When the temperature of the heat exchange medium is higher than that of the heat storage assembly, the heat storage assembly absorbs heat and stores heat; when the temperature of the heat exchange medium is lower than that of the heat storage assembly, the heat storage assembly releases heat to enable the heat exchange medium to be heated. Because the fourth heat exchange medium circulation passage 12 is vertically arranged, the dust-containing flue gas is introduced from the top end of the fourth heat exchange medium circulation passage, and after heat storage or heat release is carried out, the dust-containing flue gas is discharged from the bottom end of the fourth heat exchange medium circulation passage, and meanwhile, the smoke dust is also discharged. The fourth heat exchange medium flow path 12 is more suitable for passing dust laden flue gas than other horizontally arranged heat exchange medium flow paths.
Because the heat storage material can cause thermal expansion damage due to overlarge temperature difference, if the temperature difference of the four heat exchange media is large, the heat storage material sequentially enters each channel from low to high according to the temperature of the different heat exchange media, and in the process, the next medium can flow into the device only when the temperature of the heat storage device reaches the safe temperature. When the temperature difference of the four heat exchange media is not large, the four heat exchange media can simultaneously enter the four channels respectively to absorb heat from the pipe body. If the temperature difference of the four heat exchange media is large, the four heat exchange media sequentially enter different channels from high to low according to the temperature and flow out after absorbing heat, and in the process, the next medium can flow out of the device only when the temperature of the heat storage tank reaches the safe temperature. In the heat charging and heat releasing processes, various heat exchange media in the heat storage tank can have respective circulation passages, so that the smoke pollution is reduced, and meanwhile, the contact area between the heat exchange media and the pipe body is increased.
Examples
The first heat exchange medium is made to flow into the first heat exchange medium circulation passage 9 inside the inner tube 401 through the through holes of the third orifice plate 301, and the inner tube 401 exchanges heat with the heat exchange medium and is then discharged from the other end of the first heat exchange medium circulation passage 9.
And/or, the second heat exchange medium enters the second heat exchange medium circulation passage 10 along the through hole 1 between the third orifice plate 301 and the second orifice plate 302, and then flows into the gap between the middle pipe body 402 and the inner pipe body 401 through the through hole on the second orifice plate 302; the intermediate pipe 402 and the inner pipe 401 exchange heat with the second heat exchange medium and then are discharged from the other end of the second heat exchange medium flow path 10.
And/or, the third heat exchange medium enters the third heat exchange medium circulation passage 11 along the through hole 1 between the second orifice plate 302 and the first orifice plate 303, and then flows into the gap between the middle pipe body 402 and the outer pipe body 403 through the through hole on the first orifice plate 303; the intermediate pipe 402 and the outer pipe 403 exchange heat with the second heat exchange medium and then flow through the other end of the third heat exchange medium flow path 11.
And/or, the dust-containing flue gas enters the fourth heat exchange medium flow path 12 along the top end of the second pipe 7, flows through the outside of each outer pipe 403, exchanges heat with it, and is then discharged from the other end of the fourth heat exchange medium flow path 12.
The multichannel heat storage device provided by the utility model combines the heat storage component 4 and the limiting component 3 to establish four different heat exchange medium circulation passages; when multiple heat exchange media are led out simultaneously, different heat exchange media can have independent circulation passages, mutual pollution between different heat exchange media is avoided, multiple heat exchange media can be collected simultaneously, and heat recovery efficiency is improved. Meanwhile, the heat storage capacity of the heat storage device can be effectively increased by adopting a mode that a plurality of heat storage assemblies 4 are arranged in parallel.
