Description

Technical Field

[0001] The utility model relates to the technical field of primary network heat exchange stations, and particularly relates to a pipeline heat preservation and energy-saving device for a primary network heat exchange station. Background Technique

[0002] The primary network for heat supply in a heat exchange station refers to the pipeline network between the total heat supply source (heat supply first station or boiler room) of the central heating system and the heat exchange stations in each heating community. The equipment in the first station includes water treatment equipment, heat exchangers, various valves of different sizes, various control instruments, a control system computer, a large display screen, large and small pipelines, and water pumps. Generally, heat preservation layers are arranged outside the heating pipelines to reduce heat loss.

[0003] Currently, the invention patent with the publication number of CN218267968U discloses a pipeline heat preservation and energy-saving device for a primary network heat exchange station. A first pipe shell is sleeved on the outer surface of the pipeline, a second pipe shell is sleeved on the outer surface of the first pipe shell, clamping rings are arranged at one ends of the first pipe shell and the second pipe shell, a first heat insulation layer is sleeved on the outer surface of the second pipe shell, a second heat insulation layer is sleeved on the outer surface of the first heat insulation layer, a waterproof layer is wound on the outer surface of the second heat insulation layer, expansion joints are arranged on the outer surfaces of the first pipe shell and the second pipe shell. By sleeving the first heat insulation layer and the second heat insulation layer outside the first pipe joint respectively and binding the first heat insulation layer and the second heat insulation layer with galvanized iron wires to achieve a fixing effect, both the first heat insulation layer and the second heat insulation layer are centrifugal glass wool. In addition to the characteristics of heat preservation and heat insulation, centrifugal glass wool also has excellent shock absorption and sound absorption characteristics, providing multiple protections for the pipeline and reducing the loss of heat inside the pipeline.

[0004] During the use of the existing heat exchange station pipelines, heat preservation materials are wrapped on their surfaces to reduce the temperature loss of the water liquid inside the pipelines through passive heat preservation. The heat preservation effect is average. When the heat preservation materials are used to insulate the pipelines, heat will be transferred into the heat preservation materials, and the heat preservation materials will release the heat into the air, resulting in continuous heat loss. To solve the above problems, a pipeline heat preservation and energy-saving device for a primary network heat exchange station is proposed in this application. Content of the Utility Model

[0027] As Figures 1-4 shown, a pipeline heat preservation and energy-saving device for a primary network heat exchange station proposed by the present utility model includes a connecting water pipe 1. The surface of the connecting water pipe 1 is sleeved with a pipe sleeve 2. One end of the lower surface of the pipe sleeve 2 is conductively connected to an inlet water pipe connection seat 5, and the other end of the upper surface of the pipe sleeve 2 is conductively connected to a drain pipe connection seat 6. The inlet water pipe connection seats 5 and the drain pipe connection seats 6 of two adjacent groups of the pipe sleeves 2 are connected by a connecting hose 7.

[0028] A water storage tank 9 is arranged below the connecting water pipe 1. A circulation water pump 10 is installed on the upper surface of the water storage tank 9. The water outlet end of the circulation water pump 10 is connected to the inlet water pipe connection seat 5 through a pipeline.

[0029] A resistance wire heating plate 13 is installed at the bottom of the inner cavity of the water storage tank 9, and a constant temperature controller 12 is embedded on the surface of the water storage tank 9. The constant temperature controller 12 is electrically connected to the resistance wire heating plate 13 through a wire.

[0030] It should be noted that the constant temperature controller 12 can control the resistance wire heating plate 13 to heat the water liquid in the water storage tank 9 at a constant temperature. The hot water in the water storage tank 9 is pumped out by the circulating water pump 10 and injected into the pipe sleeve 2 and the connecting water pipe 1. The pipe sleeves 2 are connected by a connecting hose 7. The hot water circulates continuously between the pipe sleeve 2 and the connecting water pipe 1, and the water liquid finally flows back into the water storage tank 9. The hot water wraps around the surface of the connecting water pipe 1 and is continuously heated and circulated. The heat preservation sleeve 4 insulates the surface of the pipe sleeve 2, which can reduce the heat loss in the connecting water pipe 1 and improve the heat preservation and energy saving performance of the pipeline of the primary network heat exchange station.

[0031] In this embodiment, as Figure 1 and Figure 4 shown, threaded connectors 8 are movably provided at both ends of the connecting hose 7, and both ends of the connecting hose 7 are threadedly connected to the water inlet connecting seat 5 and the drain pipe connecting seat 6 through the threaded connectors 8 respectively.

[0032] It should be noted that both ends of the connecting hose 7 are threadedly connected to the water inlet connecting seat 5 and the drain pipe connecting seat 6 through the threaded connectors 8, which can realize the quick connection of the connected pipe sleeves 2.

[0033] In this embodiment, as Figure 1 shown, a liquid level observation window 11 is embedded on the surface of the side wall of the water storage tank 9. The liquid level observation window 11 is located on one side of the constant temperature controller 12. A liquid injection port 14 is formed through one side of the liquid level observation window 11, and a sealing nut is threadedly connected to the inner cavity of the liquid injection port 14.

[0034] It should be noted that the liquid level height in the water storage tank 9 can be observed through the liquid level observation window 11, and the water storage tank 9 can be replenished in time through the liquid injection port 14. After replenishment, the sealing nut can seal the liquid injection port 14.

[0035] In this embodiment, as Figure 1 shown, an automatic pressure relief valve 15 is installed on the upper surface of the water storage tank 9.

[0036] It should be noted that the heating in the water storage tank 9 will cause the air pressure to rise. When the air pressure exceeds the safety value of the automatic pressure relief valve 15, the air pressure can push up the automatic pressure relief valve 15 to realize the automatic pressure relief of the water storage tank 9, which can improve the safety during use.

[0037] In this embodiment, as Figure 3As shown, a support seat 3 is welded to the surface of the connecting water pipe 1.

By connecting the inner wall of the pipe sleeve 2 to the inner wall of the connecting water pipe 1 through the support seat 3, the structural strength of the connection between the pipe sleeve 2 and the connecting water pipe 1 can be improved. The constant temperature controller 12 can control the resistance wire heating plate 13 to heat the water liquid in the water storage tank 9 at a constant temperature. The hot water in the water storage tank 9 is pumped out through the circulation water pump 10 and injected between the pipe sleeve 2 and the connecting water pipe 1. The pipe sleeves 2 are connected by the connecting hose 7. The hot water continuously circulates between the pipe sleeve 2 and the connecting water pipe 1, and finally the water liquid still flows back into the water storage tank 9. The hot water wraps around the surface of the connecting water pipe 1 and is continuously heated and circulated. The heat preservation sleeve 4 insulates the surface of the pipe sleeve 2, which can reduce the heat loss in the connecting water pipe 1 and improve the heat preservation and energy saving performance of the pipeline of the primary network heat exchange station. The liquid level in the water storage tank 9 can be observed through the liquid level observation window 11, and the water storage tank 9 can be replenished in time through the liquid injection port 14. After the water in the water storage tank 9 is heated, the air pressure will increase.
