specific Embodiment approach 1

[0019] Specific implementation mode one: combine Figure 1 ~ Figure 4 Describe this embodiment, a system of indirect connection between heat storage tank and heating network using multi-layer insulation room in this embodiment, which includes heat storage tank 1, first hot water pipe 2, second hot water pipe 3, first cold water Pipe 4, second cold water pipe 5, heating network water supply pipe 6 and heating network return pipe 7,

[0020] It also includes a heat exchanger 8, the hot water distribution tray 1-1 in the heat storage tank 1 communicates with the heat exchanger 8 through the first hot water pipe 2, and the cold water distribution tray 1-2 in the heat storage tank 1 passes through The first cold water pipe 4 communicates with the heat exchanger 8, the heat network water supply pipe 6 communicates with the heat exchanger 8 through the second hot water pipe 3, and the heat network return pipe 7 communicates with the heat exchanger 8 through the second cold water pipe...

specific Embodiment approach 2

[0022] Specific implementation mode two: combination figure 1 To illustrate this embodiment, the first cold water pipe 4 is also provided with a cold water circulation control assembly 9, the cold water circulation control assembly 9 includes a first control valve 9-1 and a second control valve 9-2, the first control valve 9- 1 is set on the first cold water pipe 4 in parallel with the second control valve 9-2. Designed in this way, when it is not necessary to control the amount of cold water entering the heat exchanger 8, the first control valve 9-1 and the second control valve 9-2 can be opened at the same time, or only one of them can be opened. When one control valve is closed, the other control valve is closed, and operations such as cleaning can be performed on the other control valve at this time, without affecting the flow through the first cold water pipe 4 . Other compositions and connections are the same as those in the first embodiment.

Abstract

The invention discloses an indirection connection system for a heat storage tank with multiple layers of heat preservation chambers and a heat supply network and belongs to the technical field of heat supply. Through the indirection connection system, the problem that the utilization rate of heat in a heat storage tank is low due to the fact that the existing storage tank is directly connected with a heat supply network is solved. A hot water distribution disc in the heat storage tank communicates with a heat exchanger through a first hot water pipe. A cold water distribution disc in the heat storage tank communicates with the heat exchanger through a first cold water pipe. A water supply pipe of the heat supply network communicates with the heat exchanger through a second hot water pipe. A water return pipe of the heat supply network communicates with the heat exchanger through a second cold water pipe. A tank body of the heat storage tank is of a multi-layer heat preservation structure and comprises an outer shell body, a heat preservation plate layer, an inner shell body and a base; the heat preservation plate layer is located between the outer shell body and the inner shell body; moreover, a first heat preservation chamber is formed between the outer shell body and the heat preservation plate layer; a second heat preservation chamber is formed between the inner shell body and the heat preservation plate layer; and the base is a disc body. The indirection connection system for the heat storage tank with the multiple layers of heat preservation chambers and the heat supply network is used for heat supply of the heat supply network.

Description

technical field [0001] The invention relates to a system for indirect connection between heat storage tanks in multi-layer heat preservation chambers and a heat network, and belongs to the technical field of heat supply. Background technique [0002] With the development of society and economy, my country's central heating industry has developed rapidly, and the coverage of urban heating pipe networks has become larger and larger. As an energy-saving facility, heat storage tanks are often used in district heating. The accumulator stores part of the heat supplied by the heat source when the heat load is low, and supplies heat to heat users together with the heat source during the heat load peak period. The investment of heat accumulator is much lower than that of building peak-shaving heat source. It can maximize the advantages of combined heat and power and the most economical heat source, reduce the operating cost of the heating system, and enable thermal power plants and t...
