Embodiment 1

[0028] A complementary solid electric heat storage unit, comprising an outer casing 1 and a solid electric heat storage boiler 3 arranged in the inner cavity of the outer casing 1, the outer side of the solid electric heat storage boiler 3 is covered with an insulation layer 2, and the solid electric heat storage boiler 3 The air inlet end of the heat storage boiler 3 is connected to the air outlet end of the heat exchanger 5 through the upper air duct 4, the heat exchanger 5 is arranged in the inner cavity of the outer casing 1, and the air inlet end of the heat exchanger 5 passes through the lower air duct 21 Connect the air outlet end of the solid electric thermal storage boiler 3, and the fan 22 is installed on the lower air duct 21;

[0029] In this example, if Figure 1-2 As shown, the water inlet end and the water outlet end of the heat exchanger 5 are respectively equipped with a water inlet pipe 12 and an outlet pipe 6, and both the water inlet pipe 12 and the water o...

Embodiment 2

[0038] The difference between this embodiment and embodiment 1 is that, as figure 1 and 2As shown, the lower parallel connection pipe 13 in a U-shaped structure is installed through the water inlet pipe 12, and the two connection ports of the lower parallel connection pipe 13 are located outside the water inlet end and the water outlet end of the direct heating electric boiler 9 respectively. A lower parallel regulating valve 18 is installed on the lower parallel connecting pipe 13 to ensure that the water inlet pipe 12 can be adjusted by the lower parallel connecting pipe 13 and the lower parallel regulating valve 18 when the direct-heating electric boiler 9 is overhauled, and the incoming water source crosses the direct The heat-type electric boiler 9 enters the heat exchanger 5 and realizes heating water supply and heating through the solid electric heat storage boiler 3, without stopping the heating supply for maintenance, and has sufficient maintenance time.

Abstract

The invention relates to the technical field of solid electric heat storage, and provides a complementary solid electric heat storage unit. The complementary solid electric heat storage unit aims to solve the problems that a heat storage body is wasted due to the fact that the temperature difference between a cold end and a hot end of the heat storage body is large and heat storage of the heat storage body is unsaturated due to the fact that the heat storage body inside a traditional solid electric heat storage boiler is not uniform in heat storage and the heat storage body enters and exits while being heated, and the specified requirement of one for use and one for backup is not met in a heating system. The complementary solid electric heat storage unit comprises an outer shell and a solid electric heat storage boiler arranged in an inner cavity of the outer shell, wherein the outer side of the solid electric heat storage boiler is coated with a heat preservation layer, the air inletend of the solid electric heat storage boiler is connected with the air outlet end of a heat exchanger through an upper air duct, and the heat exchanger is arranged in the inner cavity of the outer shell; and the air inlet end of the heat exchanger is connected with the air outlet end of the solid electric heat storage boiler through a lower air duct, and a fan is arranged on the lower air duct. The complementary solid electric heat storage unit is particularly suitable for cooperative work of two heating systems required by heat supply for continuous heat supply, and has high social use valueand application prospect.

Description

technical field [0001] The invention relates to the technical field of solid electric heat storage technology, in particular to a complementary solid electric heat storage unit. Background technique [0002] The regenerative electric boiler is a new type of high-efficiency and energy-saving electric heating product launched according to the policy of the electric power department to encourage the use of electricity for heating during low-peak periods and to enjoy preferential electricity prices. Auxiliary equipment and heat storage tanks constitute a regenerative electric boiler system. [0003] The traditional solid electric heat storage boiler is composed of a heat storage body, an insulation layer, a heat exchanger, a fan, a skeleton and an electric control cabinet. The heat storage of the internal heat storage body is not uniform. The temperature difference between the hot and cold ends of the heating body is large, and the heat storage of the heat storage body is not s...
