Description

Technical Field

[0001] The utility model relates to a steam thermal energy heat storage tank device, belonging to the technical field of steam energy storage. Background Art

[0002] A steam thermal energy storage tank is a technical device for storing and releasing thermal energy, and is mainly used for the time-shift utilization of thermal energy. A steam inlet for connecting a steam delivery pipe is installed on the tank body of the steam thermal energy storage tank, wherein the relative positions of the steam inlet and the tank body are fixed. Therefore, when high-temperature steam enters the tank body through the steam inlet to exchange heat with the water in the tank body, there is a situation where the part of the tank body where the steam inlet is installed is heated unevenly, that is, when high-temperature steam enters the tank body through the steam inlet, the high-temperature steam will heat the part of the tank body where the steam inlet is installed by heat conduction, so that the temperature of the part of the tank body where the steam inlet is installed increases, while the temperature of the area on the surface of the tank body far from the steam inlet is lower, that is, the temperature of the surface of the tank body with the steam inlet as the center gradually decreases outward, at this time, the part of the tank body where the steam inlet is installed generates stress due to uneven heating, and at this time, the part of the tank body where the steam inlet is installed generates stress concentration due to uneven heating, which can easily induce damage to the part of the tank body where the steam inlet is installed.

[0010] Beneficial effects of the utility model:

[0011] 1. Insert the steam inlet in the oblong opening, and connect the steam inlet and the steam distribution pipe with an elbow. When the electric push rod is controlled to extend and retract, the electric push rod drives the structure formed by the lower semicircular sleeve and the upper semicircular sleeve to slide along the tank body. At this time, the position of the steam inlet in the oblong opening changes. At this time, the steam inlet drives the steam distribution pipe to move in the tank body through the elbow, so that the steam inlet and the steam distribution pipe are moved to different parts of the tank body, that is, the relative positions of the steam inlet, the steam distribution pipe and the tank body are adjustable, so that the area of ​​the tank body where the steam inlet is installed is evenly heated at the initial stage of high-temperature steam, to prevent the part of the tank body where the steam inlet is installed from being damaged due to stress concentration caused by uneven heating. After the overall temperature of the tank body tends to be stable, cut off the circuit of the electric push rod.

[0012] 2. When connecting the upper semicircular sleeve and the lower semicircular sleeve by means of connecting screws and nuts, one end of the connecting screw is passed through the upper connecting bar, the lower connecting bar and the supporting bar in sequence, and then the nut is screwed onto the connecting screw. At this time, under the support of the supporting bar, the nut is not in contact with the lower connecting bar. When the nut and the connecting screw cannot be separated by conventional tools, the gap between the supporting bar and the lower connecting bar can be used to cut off the connecting screw, thereby providing an alternative method for separating the lower semicircular sleeve and the upper semicircular sleeve.

[0013] 3. After the structure formed by the lower semicircular sleeve and the upper semicircular sleeve is installed on the tank body, the rubber pad is located between the upper semicircular sleeve and the tank body. On the one hand, the rubber pad improves the sealing between the upper semicircular sleeve and the tank body, and on the other hand, the rubber pad can be squeezed, thereby providing a buffer for the thermal expansion and contraction of the upper semicircular sleeve.

[0014] 4. After the high-temperature steam enters the steam distribution pipe through the steam inlet and the channel formed by the elbow, the high-temperature steam flows into the water in the tank through multiple exhaust pipes to heat the water in the tank, thereby achieving the heat storage of steam thermal energy.
