Problems solved by technology

At the same time, the effect of the phase change material on the base material, the stress generated during the phase change process of the phase change material makes the base material easy to damage, and it will also have a certain degree of corrosion on the auxiliary equipment
And these will reduce the working efficiency of heat storage equipment
In the face of these problems in practical applications, the traditional form of heat accumulator can only reduce the aging of phase change materials by controlling the heat exchange frequency and optimizing heat storage materials, reduce the corrosion effect of phase change materials on equipment, and increase production. cost, and when the problem is formed and affects production, it must be shut down to clean the interior of the heat accumulator and replace the material. After the cleaning and replacement work is completed, the heat accumulator can continue to work, affecting the production schedule
[0004] On the other hand, heat accumulators are constantly being developed and updated. When heat exchange tubes with higher heat exchange efficiency are invented, traditional heat accumulators can only be optimized and upgraded by replacing the entire equipment. efficiency, but increased production costs not commensurate with the increased efficiency

Embodiment 1

[0039] The object of the present invention is to provide a heat accumulator with a replaceable inner core, which includes a heat exchange core and an outer shell. The shell is a cylindrical structure consisting of a shell 1, an upper plate 3, a bottom plate 2, a hemispherical collector 14 and a support frame 15, and the shell 1, the bottom plate 2, the hemispherical collector 14 and the support frame 15 are integrally formed by welding. The upper platen 3 is provided with a hot water inlet pipe 4 and a handle 7, the handle 7 is arranged symmetrically along the center of the upper platen 3, the hot water inlet pipe 4 is arranged at the center of the upper platen 3, and the hot water inlet pipe 4 and the upper platen 3 are threaded.

[0040] The heat exchange core is composed of a water separator 12, a heat exchange tube 8 and a water collector 13. The water separator 12 and the water collector 13 are respectively fixed and sealed at both ends of the heat exchange tube 8.

[004...

Embodiment 2

[0054] The heat exchange tube 8, the water separator 12 and the water collector 13 are all screwed and sealed. The same as the first embodiment, the heat exchange core can be replaced as a whole. When individual heat exchange tubes 8 fail, single Replacement of parts does not affect the overall working capacity of the heat exchange core.

[0055] When the heat exchange tube 8 needs to be replaced, first take out the heat exchange core, remove the heat exchange tube 8 to be replaced, and then install a new heat exchange tube 8, and the rest of the steps are the same as the steps for replacing the heat exchange core.

[0056] Other parts of the device are the same as in Embodiment 1.

Abstract

The invention provides a heat accumulator with a changeable inner core. The heat accumulator with the changeable inner core comprises a heat exchange core and a shell; the shell comprises a shell body, an upper pressure plate and a bottom plate; the upper pressure plate and the bottom plate are separately arranged at the two ends of the shell body to form a cavity for filling a heat accumulation material; the upper pressure plate is detachably connected with the shell body; an upper pressure plate sealing ring is arranged on the lower surface of the upper pressure plate; a bottom plate sealingring is arranged on the upper surface of the bottom plate; the heat exchange core is arranged in the shell body, and is connected with the upper pressure plate and the bottom plate through pressure applied by the upper pressure plate; the heat exchange core comprises a heat exchange tube, a water distributor and a water collector; the water distributor and the water collector are arranged at thetwo ends of the heat exchange tube; the water distributor is matched with the upper pressure plate seating ring, and the water distributor and the upper pressure plate form a water inlet closed cavity; and the water collector is matched with the bottom plate sealing ring, and the water collector and the bottom plate form a water outlet closed cavity. The heat exchange core can be conveniently andrapidly changed integrally, thus, operations such as maintenance, repair, scale removal and upgrading of the heat accumulator are realized by a simple and rapid mode, the related working time and production costs are saved, and the corrosion of a phase change material to equipment is reduced.

Description

technical field [0001] The invention relates to the heat storage field in a new energy heating system, in particular to a heat storage with a replaceable inner core and a replacement method. Background technique [0002] The heat storage system refers to a system that adopts an appropriate method and uses a specific device to store temporarily unused or excess heat through a certain heat storage material, and then release it for use when needed. The heat accumulator is an energy-saving device that realizes heat transfer between materials and heat storage between two or more fluids at different temperatures. The work of the heat accumulator is divided into two stages: heat storage and heat release. In the heat storage stage, the heat is transferred from the higher temperature fluid to the lower temperature heat storage material, heating the heat storage material for heat storage; in the heat release stage, the heat is transferred from the heat storage material to the lower te...
