As shown in fig. 1, in some embodiments, the accumulator chamber 110 includes a lower chamber 113, a middle chamber 112, and an upper chamber 111 connected in series. Specifically, the lower chamber 113, the middle chamber 112, and the upper chamber 111 are arranged in a direction from bottom to top, the upper chamber 111 is located at the upper portion of the reservoir chamber 110, and the lower chamber 113 is located at the lower portion of the reservoir chamber 110. The up-down direction is the direction indicated by the arrow a in fig. 1.
The water outlet pipe 120 is communicated with the upper section cavity 111, namely the water outlet pipe 120 is communicated with the upper part of the water storage cavity 110. The higher the height in the reservoir chamber 110, the higher the temperature of the water, and therefore the outlet pipe 120 is located at the upper part of the reservoir chamber 110 so that the water body reaching the outlet temperature can easily flow out of the outlet pipe 120.
The water return pipe 130 is communicated with the lower chamber 113, that is, the water return pipe 130 is communicated with the lower portion of the water storage chamber 110. Therefore, the water body entering the water storage cavity 110 from the water return pipe 130 is firstly positioned at the lower part of the water storage cavity 110, thereby facilitating the heat exchange of cold water, and hot water to flow out from the upper part of the water storage cavity 110 is not influenced, so that the heat storage water tank 100 is more energy-saving.
In some embodiments, at least a portion of the electrical heating tube 200 is located in the middle section chamber 112. The middle chamber 112 is located in the middle of the water storage chamber 110, and the height of the middle chamber 112 is lower than that of the upper chamber 111. The heating part of the electric heating pipe 200 is arranged in the middle chamber 112 of the water storage chamber 110, so that the electric heating pipe 200 is more convenient to install, the water in the water storage chamber 110 is more uniformly heated, and the water in the water storage chamber 110 can rise to the upper part of the water storage chamber 110 after being heated in the middle of the water storage chamber 110 and is conveyed to a heat supply pipe network.
In some embodiments, at least a portion of the electrical heating tube 200 is located in the upper chamber section 111. The upper chamber 111 is located in the upper part of the reservoir cavity 110, i.e. at least part of the electric heating tube 200 is located in the upper part of the reservoir cavity 110. Therefore, the electric heating pipe 200 can rapidly heat the water body on the upper part of the water storage cavity 110, and the water on the upper part of the heat storage cavity 110 can be conveniently heated to meet the requirement of the outlet water temperature of the heat supply pipe network.
In other embodiments, the electric heating tube 200 may be disposed in both the upper chamber 111 and the middle chamber 112 to further improve the heating efficiency of the electric heating tube 200.
In some embodiments, the electric heating pipe 200 is connected to the body of the hot water storage tank 100. For example, an electric heating pipe 200 extending in a horizontal direction is installed on the sidewall 103 of the hot water storage tank 100, and a heating portion of the electric heating pipe 200 is extended into the water storage chamber 110.
In some embodiments, a plurality of electric heating pipes 200 are spaced apart along the height of the accumulator chamber 110. The height direction of the reservoir chamber 110 is the up-down direction. That is, a plurality of electric heating pipes 200 distributed at intervals in the up-down direction can heat the water in the reservoir chamber 110. For example, four electric-heating pipes 200 are provided, and the four electric-heating pipes 200 are spaced apart from each other in the vertical direction on the side wall 103 of the hot water storage tank 100.
In some embodiments, a plurality of electrical heating tubes 200 are spaced circumferentially along the accumulator chamber 110. That is, a plurality of electric heating pipes 200 spaced along the circumference of the reservoir chamber 110 can heat the water in the reservoir chamber 110. For example, six electric-heating pipes 200 are provided, six electric-heating pipes 200 are on the same horizontal plane, and six electric-heating pipes 200 are distributed on the side wall 103 of the hot water storage tank 100 at intervals along the circumferential direction of the water storage cavity 110.
In other embodiments, a part of the electric heating pipes 200 are distributed at intervals along the height direction of the reservoir cavity 110, and another part of the electric heating pipes 200 are distributed at intervals along the circumferential direction of the reservoir cavity 110, thereby further improving the heating efficiency of the electric heating pipes 200.
In some embodiments, the outlet pipe 120 is adjacent to the top wall 101 of the upper chamber section 111. That is, the outlet pipe 120 communicates with the upper portion of the reservoir chamber 110. For example, the inlet of the outlet pipe 120 is located below the level of the reservoir chamber 110 and the inlet of the outlet pipe 120 is adjacent the level of the reservoir chamber 110. The higher the elevation within the impoundment chamber 110, the higher the temperature of the body of water. Thus, the outlet pipe 120 is located at an upper portion of the reservoir chamber 110 so that the body of water reaching the outlet temperature is readily discharged from the outlet pipe 120.
The return pipe 130 is adjacent to the bottom wall 102 of the lower stage chamber 113. That is, the return pipe 130 communicates with the lower portion of the reservoir chamber 110. Therefore, the water entering the water storage cavity 110 from the water return pipe 130 is firstly positioned at the lower part of the water storage cavity 110, thereby facilitating the heat exchange of the cold water, and the hot water to be sent out from the upper part of the water storage cavity 110 is not influenced, so that the heat storage water tank 100 is more energy-saving.
As shown in fig. 1, in some embodiments, an electrically heated hot water storage tank system 1000 with a horizontal heating pipe further includes a controller 300. The controller 300 is electrically connected to the electric heating tube 200 and is used to control the on/off of the electric heating tube 200. The controller 300 can control the heating of the electric heating tube 200, so that the water temperature in the electric heating hot water storage tank system 1000 with the horizontal heating tube can meet the use requirement, and energy can be saved by cutting off the power or adjusting the power consumption of the electric heating tube 200.
In some embodiments, the electrically heated hot water storage tank system 1000 with horizontal heating pipes further comprises a temperature sensor. A temperature sensor is mounted in the reservoir chamber 110 and electrically connected to the controller 300, the temperature sensor being adjacent the outlet pipe 120. The temperature sensor can detect the outlet water temperature of the outlet pipe 120 so as to facilitate the controller 300 to adjust the electric heating pipe 200. Specifically, when the temperature sensor detects that the outlet water temperature of the water pipe 120 is low, the controller 300 may control the electric heating pipe 200 to be powered on. When the temperature sensor detects that the outlet water temperature of the water pipe 120 is high, the controller 300 may control the electric heating pipe 200 to be powered off.
The utility model also provides an energy storage peak-shaving frequency modulation system which comprises the electric heating heat storage water tank system 1000 with the horizontal heating pipe. The electric heating heat storage water tank system 1000 with the horizontal heating pipes can be used as an external peak-regulating and frequency-modulating device of the thermal power generating unit, can be rapidly adjusted according to external load changes of the thermal power generating unit, reduces the overall cost of the external peak-regulating and frequency-modulating device, and solves the problem of influences of lifting loads on the service life of the unit and operators.
