The outer casing 1 and the inner casing 2 are nested with each other, and the heat insulation layer 4 is arranged between the outer casing 1 and the inner casing 2 to prevent heat loss of the movable multifunctional heat storage device. Four heat storage units 3 of thermal phase change heat storage materials are evenly distributed in the inner casing 2 with gaps between them. The temperature measuring device 5 is connected with the heat storage unit 3 of the thermal phase change heat storage material, and is used for detecting the temperature of the heat storage unit 3 of the thermal phase change heat storage material. The sliding buckle 6 is arranged on the outer ...

Embodiment 2

[0043] 1) Preparation of porous bacterial cellulose: Cut the bacterial cellulose BC soaked in deionized water to pH = 7 into small pieces (about 1×1cm), clean the pieces and put them in the refrigerator to freeze and freeze-dry 24 h. The obtained samples were placed in a tube furnace at N 2 Under protected conditions, the temperature was programmed to heat carbonization, and the temperature was raised to 350 °C at a rate of 1.5 °C / min for 1 h, and then the temperature was raised to 800 °C at a rate of 3 °C / min for 2 h to obtain porous bacterial cellulose . The schematic diagram of its preparation process is shown in figure 2 shown.

[0044] 2) Weigh 0.5 gBa(OH) 2 ·8H 2 O into the cup, add a small amount of deionized water (the deionized water is just enough to wet the solid particles), and then heat it in a common box at 80°C for 2 hours to make Ba(OH) 2 ·8H 2 O is completely melted, then add 0.08g of surfactant OP-10, and ultrasonically disperse for 30min to form a st...

Embodiment 3

[0046] 1) Preparation of porous bacterial cellulose: Cut the bacterial cellulose BC soaked in deionized water to pH = 7 into small pieces (about 1×1cm), clean the pieces and put them in the refrigerator to freeze and freeze-dry 24 h. The obtained samples were placed in a tube furnace at N 2 Under protected conditions, the temperature was programmed to heat carbonization, and the temperature was raised to 350 °C at a rate of 1.5 °C / min for 1 h, and then the temperature was raised to 800 °C at a rate of 3 °C / min for 2 h to obtain porous bacterial cellulose .

[0047] 2) Weigh 0.5 g Na 2 SO 4 ・10H 2 O is put into the cup, add a small amount of deionized water (the deionized water is just enough to wet the solid particles), and then heat it at 80 ° C for 2 hours in a common box to make Na 2 SO 4 ・10H 2 O was completely melted, then 0.08 g of surfactant OP-10 was added, and ultrasonically dispersed for 30 min to form a stable emulsion. Add 0.5 g of porous bacterial cellulos...

The invention discloses application of a heat phase change heat storage material in a movable multifunctional heat storage device, and belongs to the technical field of energy saving devices. The movable multifunctional heat storage device includes an outer shell, an inner shell, an insulating layer, a plurality of composite phase change heat storage material heat storage units, a temperature measuring device, and a sliding buckle, wherein the insulating layer is arranged between the outer shell and the inner shell, the composite phase change heat storage material heat storage units are inseton the inner side of the inner shell, the temperature measuring device is connected to the phase change heat storage material heat storage units, the sliding buckle is arranged on the outer side of the outer shell, and heat exchange pipelines are arranged in the interiors and gaps of the heat phase change heat storage material heat storage units. According to the application, the movable multifunctional heat storage device stores heat into the movable multifunctional heat storage device in a radiation and convection heat transfer mode, efficient heat addition output can be conducted by movingthe movable multifunctional heat storage device to the user location, through simple integration, the overall heat storage capacity is improved, and storage, transfer and utilization of heat dissipation waste heat are further realized.

Description

technical field [0001] The invention relates to the technical field of phase-change heat storage materials and energy-saving devices, in particular, it relates to the application of a thermal phase-change heat storage material in a movable multifunctional heat storage device. Background technique [0002] The energy utilization level of my country's power plant and boiler heating industry is relatively low, especially for medium and low temperature heat sources, waste heat is seriously wasted. How to use these low-grade industrial waste heat for rural and urban heating has very important practical significance for northern cities shrouded in smog. Considering the variety of low-taste waste heat, its heat source form, quantity, time and space have great uncertainty and instability. Therefore, a technology and device for efficiently utilizing low-taste waste heat are needed. Among them, thermal phase change energy storage technology is a method to effectively realize the effi...
