Abstract
The utility model provides an electric heating phase-changing heat accumulator for industrial high-temperature gases. The gas is heated after flowing through preheated heat storage medium, and is used for heating operations. The utility model adopts metal phase-change material with large heat capacity and large phase-change potential heat to be as the heat storage medium. An electric heating element, a heat exchange pipe and the heat storage medium are combined into a whole to form an electric heating energy storage body. The utility model adopts the double-layer heat-insulation measures of heat-insulation layer, an air interlayer used as the hot air exchange and inlet channel, etc. The utility model effectively avoids secondary heat loss, reduces the volume of the heat accumulator, and has high heat efficiency.
Description
The utility model belongs to a kind of regenerative apparatus that high-temperature gas is provided for industry.
Industrial at present, as fields such as industrially drying, regenerating molecular sieves, the normal electric heating storage heater that uses produces high-temperature gas for the usefulness that adds hot work, and general electric heating storage heater is that to be provided with one after electric heater be the sensible heat storage heater of heat storage medium with the refractory material.When accumulation of heat, after the heating surface that gas flows through electric heater is heated, flow into again in the storage heater, carry out heat exchange with heat storage medium in the storage heater, thereby heat is stored in the storage heater.When needs add hot work, make gas flow through heat storage medium in the storage heater of accumulation of heat, gas promptly is heated to form high temperature for use.This electric heating heat accumulator system volume is big, and the thermal efficiency is low, and has shortcomings such as secondary heat exchange loss and dust pollution.
The purpose of this utility model is the problem that exists at prior art, proposes a kind of electric heating and accumulation of heat to be combined as a whole, and can avoid secondary heat exchange to lose and dust pollution the electric heating phase change heat accumulator that the thermal efficiency is higher.
The technical solution of the utility model mainly is to adopt thermal capacitance is big and latent heat of phase change is big metal phase change energy-storage material as heat storage medium, heating and heat storage medium be combined as a whole form the electric heating energy-storage body, place housing with inlet and outlet, by heating to heat storage medium preheating accumulation of energy after, make gas flow through heat storage medium and carry out heat exchange and become high temperature gas flow going out.Its design feature is to have a shell body that inlet and outlet is arranged, in shell body, be provided with an inner core, shell body, the air blanketing that one double as airintake wind-tunnel is arranged between the inner core, central authorities' installing electric heating energy-storage body at inner core, the electric heating energy-storage body with fusing point at metal phase change energy-storage materials such as the aluminium alloy of 360 ℃～600 ℃ of scopes or zinc-containing alloys as heat storage medium, be embedded with heat exchanger tube and heating in this heat storage medium, filling heat insulating wall between electric heating energy-storage body and inner core, the air inlet of heat exchanger tube and shell body, air blanketing between the inner core communicates, and the gas outlet of heat exchanger tube and the air outlet of shell body communicate.
The heat storage medium of electric heating energy-storage body can adopt any in the following material:
(1). alusil alloy, wherein the content of silicon is 0～20% (percentage by weight, as follows);
(2). almag, wherein the content of magnesium is 0～30%;
(3). aldray, wherein the content of magnesium is 0～15%, the content of silicon is 0～17%;
(4). aluminium magnesium copper alloy, wherein the content of magnesium is 0～15%, the content of copper is 0～17%;
(5). the aluminum bronze silicon alloy, wherein the content of copper is 0～17%, the content of silicon is 0～15%;
(6). zinc-containing alloy, its component is: zinc 70～98%, aluminium 0～24%, copper 0～10%, magnesium 0.1～
2％。
Between electric heating energy-storage body and inner core, can fill heat-insulating materials such as alumina silicate, calcium silicates, rock wool or perlite as heat-insulation layer.
The heat exchanger tube that is embedded in the electric heating energy-storage body can adopt straight tube, also can adopt snake bend.
The utility model is owing to adopted the metal phase change energy-storage material of energy storage density height and good heat-transfer as heat storage medium, heating and heat exchanger tube are buried notes in heat accumulating, thereby electric heating and accumulation of heat are combined as a whole, not only avoid the secondary heat loss but also dwindled the volume of storage heater widely, simultaneously owing to adopt the double-layer heat insulation measures such as air blanketing of heat-insulation layer and double as exchanging air airintake wind-tunnel, thereby has the higher thermal efficiency, its thermal efficiency can reach more than 95%, reaches 20～30% than common storage heater is energy-conservation.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is the structural representation of electric heating phase change heat accumulator.
As shown in the figure, the electric heating phase change heat accumulator has columnar shell body 1, inner core 2 is arranged in the shell body, the air blanketing 3 that the double as airintake wind-tunnel is arranged between inner core and the shell body, the upper side wall of shell body has air inlet 4 to communicate with air blanketing, the central authorities of inner core 2 install tubular electric heating energy-storage body 5, this electric heating energy-storage body with alusil alloy [siliceous 15% (percentage by weight)] metal phase change energy-storage material as heat storage medium, straight tube shape heat exchanger tube 7 and heating 8 are cast among the heat accumulating 6, has one deck heat-insulation layer 9 between electric heating energy-storage body 5 and the inner core 2, the heat-insulation material of filling is a perlite, heat exchanger tube 7 bottom air inlets in the electric heating energy-storage body communicate with air blanketing 3 by inner core bottom air cavity 10, the air outlet 11 that gas outlet, heat exchanger tube 7 top is guided the shell body top into.This electric heating phase change heat accumulator is by heating 8 work in the automatic temperature control control electric heating energy-storage body, and when making heating to the preheating of electric heating energy-storage body, the temperature of control energy storage body can not surpass phase point temperature (generally about 600 ℃).
