Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
As shown in fig. 1, a compact overhead heat-accumulating tank device capable of being quickly hoisted and replaced includes a heat-accumulating tank 10, and the heat-accumulating tank 10 is divided into an upper heat-accumulating tank body 101 and a lower heat-accumulating tank body 102 disposed at the bottom of the upper heat-accumulating tank body 101. The joints of the upper heat storage tank body 101 and the lower heat storage tank body 102 are provided with thickened flanges 20 for connection. The upper heat accumulation case 101 is provided with a heat accumulation chamber 12 and a thermal state bin 36. A heat storage medium 14 is provided in the heat storage chamber 12, and the heat storage medium 14 is a heat storage ball or the like. The regenerative chamber 12 is connected to a thermal storage medium discharge door 16 provided on the upper thermal storage case 101. The bottom of the regenerator 12 is provided with a grate 18, and the grate 18 is of a steel structure. The lower heat storage tank 102 is provided with a cold chamber 38 and a cold air/flue gas inlet/outlet flange (also called cold air flue gas inlet/outlet flange) 26 communicating with the cold chamber 38. The heat storage tank 10 is divided into upper and lower sections from a position near the height of the grate 18. A thermal state air/flue gas channel (also called a thermal state air flue gas channel) 22 is poured inside the heat storage box 10 by a high-temperature resistant heat insulation material 24, and the heat insulation material 24 is a refractory pouring material capable of bearing the working temperature of the heat storage box 10. The thermal state air/flue gas channel 22 is connected with a thermal state interface flange 32 arranged at the bottom of the lower heat accumulation box body 102, and the thermal state air/flue gas channel 22 is communicated with the thermal state bin 36.
When in use, because the thermal state air/flue gas channel 22 is positioned in the heat storage box 10, the high-temperature flue gas after heat exchange flows downwards through the channel and finally enters a burner nozzle (not shown) connected with the thermal state interface flange 32 for combustion; when the reversing valve operates in a reversing mode, high-temperature flue gas sucked from the nozzle spray head enters from the upper part of the heat storage chamber 12 through the built-in hot air/flue gas channel 22 of the heat storage box 10, and is discharged from the bottom of the box body after heat exchange.
