[0050] 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 under 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 .

[0051] 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 cellu...

Abstract

The invention discloses an 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 comprises an outer shell, an inner shell, an insulating layer arranged between the outer shell and the inner shell, a plurality of composite phase change heatstorage material heat storage units which are embedded onto the inner side of the inner shell and are arranged in a spaced manner, a temperature measuring device connected to the phase change heat storage material heat storage units and a sliding buckle arranged on the outer side of the outer shell. Heat exchange pipelines are arranged in the phase change heat storage material heat storage unitsand in gaps between the phase change heat storage material heat storage units. The movable multifunctional heat storage device stores heat by heat transfer modes of radiation and convection. By movingthe movable multifunctional heat storage device to a user location, heat can be supplied and output efficiently. By means of simple integration, the whole heat storage ability is improved, and storage, transfer and utilization of radiating residual heat are achieved further.

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...
