It should be noted that: the energy storage clamping groove units 3 can be adjusted according to the actual demands of users so as to change the number of the parallel energy storage units 4 and improve the flexibility and adaptability of the device;
working principle: in order to make the energy storage unit 4 have higher efficiency in the energy storage or energy release stage and more uniform overall temperature, the overall energy storage unit 4 is divided into an upper layer and a lower layer by a partition plate 43, and the inner cavity of the third box body 41 is divided into an upper energy storage inner cavity and a lower energy storage inner cavity; firstly, injecting a phase-change material with high phase-change temperature into a first filling port 6, and injecting a phase-change material with low phase-change temperature into a second filling port 7, so that the phase-change material with high phase-change temperature fills an upper energy storage cavity, and the phase-change material with low phase-change temperature fills a lower energy storage cavity; then the valve 55 is opened, the high-temperature steam of the industrial waste gas is conveyed to the port of the main pipeline 51 communicated with the upper through hole 34, so that the high-temperature steam is filled in the pipe of the inner pipeline 42 in the energy storage unit 4 to store heat, when the heat is stored, the temperature of the high-temperature steam is higher as the pipeline extends and is gradually encrypted, the temperature difference between the high-temperature steam and the phase-change material is larger, the heat exchange efficiency is high, the sparse spiral rib 46 is utilized to slow down the heat exchange of the high-temperature steam of the upper inner pipeline 42, the heat is transferred to the phase-change material of the upper high phase-change point through the sparse spiral rib 46, the heat is absorbed, liquefied and stored, the heat exchange is intensified by the dense spiral rib 46 along with the reduction of the temperature of the steam, the spiral rib 46 outside the lower inner pipeline 42 is gradually encrypted to strengthen the heat exchange of the steam, the partial steam of the lower inner pipeline 42 is condensed, the temperature of the vapor-liquid mixture is reduced, heat is transferred to the phase-change material with a lower layer and a low phase-change point through the denser spiral ribs 46, so that the phase-change material absorbs heat, liquefies and stores energy, condensed water is respectively discharged from the inner pipeline 42 and the drain pipe 32, after the condensed water is discharged, the valve 55 of the inlet and the outlet is closed, then the cover 1 and the heat insulation layer 9 of the first box body 2 are opened, the branch pipe quick connector 54 is opened by rotating, when the branch pipe quick connector 54 is opened, as shown in a schematic diagram of the situation that the inner pipe protruding from the branch pipe quick connector 54 is retracted into the upper through hole 34 and the lower through hole 35 after the third box body of the first row is taken out in the position b in fig. 7, at this time, the handle 45 of the energy storage unit is manually grasped, a plurality of third box bodies 41 of the device are pulled out from the energy storage clamping groove unit 3, a plurality of new third box bodies 41 are reinstalled in the energy storage clamping groove unit 3 of the device to continue the heat storage work, after the extracted plurality of third boxes 41 after heat storage are placed into the new energy storage clamping groove unit 3, manually rotating and closing the branch pipe quick connectors 54 in the new energy storage clamping groove unit 3 again, so that the inner pipes of the branch pipe quick connectors 54 extend out of the upper through holes 34 and the lower through holes 35, as shown in a second row c in fig. 7; finally, after waiting for truck transportation, firstly, cold water is conveyed into the port of the main pipeline 51 communicated with the lower through hole 35 of the device after being transported to the corresponding place to be heated, so that the low-temperature water can fully fill the inner pipeline 42 of the energy storage unit 4 to release heat, and when the heat is released, the cold water exchanges heat with the phase change material with lower temperature, the heat exchange can be enhanced by the spiral ribs 46 densely outside the pipeline due to the low temperature, and the sparse spiral ribs 46 flow into the upper high-temperature phase change material along with the inner pipeline 42, so that the heat loss is reduced on the premise of ensuring the outlet temperature, and the remote heating is realized. The cold water in the lower section of the inner pipeline 42 passes through the dense spiral ribs 46 to absorb the heat in the phase change material with a low phase change point, so that the heat is released, and when the cold water in the inner pipeline 42 flows into the upper section of the energy storage unit 4, the temperature difference between the inside and the outside of the pipeline is large due to the characteristic of the high phase change point of the upper layer of the phase change material, the heat transfer efficiency is high, and the relatively dense spiral ribs 46 weaken the heat exchange process, so that the heat in the energy storage unit 4 is reserved to a great extent on the premise that the outlet temperature reaches the requirement.
In summary, because of the limitation of the delivery port of the industrial high-temperature steam, the device can carry out circulated heat storage by disassembling and installing the third box 41 in the energy storage clamping groove unit 3, thereby saving the time cost, saving the later maintenance cost, realizing the heat gradient utilization of the waste steam by the upper and lower layering of the energy storage unit 4 and the gradual density of the spiral ribs 46, strengthening the heat exchange to ensure that the inner temperature of the upper and lower layers of the energy storage unit 4 is uniform, effectively relieving the defect of unbalanced temperature of the energy storage unit 4, ensuring that the energy loss is reduced in the heat release process, improving the heat charging and discharging speed and greatly improving the heat exchange efficiency.

The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
