Description

Technical Field

[0001] The utility model belongs to the technical field of hot water storage tanks, in particular to a heat preservation structure of a steam transport pipeline and a hot water storage tank. Background Art

[0002] In daily life and production processes, the heat storage tank is a common energy storage device, which is mainly used to store steam and provide it to equipment that needs heat. The heat storage tank is generally composed of a water tank, a steam transportation pipeline, a heat preservation structure and a heating structure. The water in the water tank is heated by the heating structure, and the steam in the water tank is kept warm by the heat preservation structure. At the same time, the steam in the water tank is transported to other equipment through the steam transportation pipeline.

[0003] However, it still has the following disadvantages in actual use:

[0004] The above-mentioned hot water storage tank transports steam through its steam transport pipe. However, during use, the material of the steam transport pipe itself is used to prevent heat loss during transportation, and its thermal insulation performance is poor. In addition, during transportation, the steam in the pipe may exert external force on the pipe itself, causing the pipe itself to vibrate, which may cause the connection between the pipe itself and the hot water storage tank or other equipment to fall off, affecting the steam transportation efficiency.

[0005] The above-mentioned hot water storage tank uses an insulation structure to insulate the internal steam. However, during use, the insulation structure of the hot water storage tank is generally insulated from part of the heat transfer by insulation cotton or insulation film, which can only slow down the rate of heat loss, but cannot ensure that the temperature in the hot water storage tank is maintained within a certain temperature range for a long time.

[0006] To this end, we provide a steam transport pipeline and a heat preservation structure of a hot water storage tank to solve the above problems. Utility Model Content
