Description

Technical Field

[0001] The utility model relates to the field of heat storage equipment, in particular to a heat storage device for a steam generator. Background Technique

[0002] As an efficient energy-saving and emission-reduction device for improving the reliability and economy of steam use, steam accumulators are widely used in industrial production fields such as medicine, chemical fiber, food, printing and dyeing, and distributed energy. The heat storage solid bricks of the existing heat storage device generate heat exchange with the water in the boiler through the flowing air current, and then release the stored heat energy to heat the water in the boiler. However, in the existing heat storage device, the gas passage between the heat storage device and the boiler is in an unobstructed state, so that the heat in the heat storage device dissipates through the air flow passage during the energy storage process, resulting in heat loss.

[0003] The patent document with the application number 202310331434.9 discloses a solid heat storage device for steam boiler energy storage. Through the relative movement of the moving plate and the fixed plate, when heat release is required, the first ventilation holes and the second ventilation holes on the moving plate and the fixed plate are aligned and penetrated. The high-temperature blower is used to transport the gas, so that the heat in the storage cabinet is extracted from the air outlet cavity to the heat exchanger for heat exchange, and enters the storage cabinet from the side of the air inlet cavity. Under the heating of the heat storage bricks in the storage cabinet, the gas circulates to realize the conversion of the heat energy in the heat storage bricks into the heat energy of the water medium in the heat exchanger, so as to realize the storage of the electric energy during the low-power period and use it during the peak period; when the heat of the heat storage bricks is not used during the low-power period and heat release is not required, the moving plate moves, so that the first ventilation hole and the second ventilation hole are misaligned, and then the air flow passage between the first ventilation hole and the second ventilation hole is closed, and the first shutter is in a horizontal state to close the ventilation groove, so that the air inlet cavity and the air outlet cavity form a closed heat insulation chamber, making the heat in the storage cabinet not easy to flow out, thereby improving the heat storage effect. Although this device can fully achieve the purpose of improving heat storage, its structure is relatively complex and the operation process is relatively cumbersome. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a heat storage device for a steam generator with convenient operation and simple structure.

[0005] The technical solution adopted by the utility model to solve its technical problems is: the heat storage device for the steam generator includes a heat storage box, a storage cabinet arranged in the heat storage box, lifting plates arranged on both sides of the heat storage box, and an air flow passage arranged around the storage cabinet, and further includes a first air flow valve plate arranged below the lifting plates;

[0006] The storage cabinet, the heat storage box and the first air flow valve plate respectively form a first channel on both sides of the storage cabinet;

[0007] A second channel is provided below the storage cabinet. A heat exchanger is arranged in the second channel. Second air flow valve plates are arranged at the upper parts of both ends of the second channel. Diversion holes are arranged in a staggered manner on the first air flow valve plate and the second air flow valve plates. The first channel and the second channel form the air flow channel.

[0008] Furthermore, a surrounding plate is arranged along the vertical direction on the periphery of the second air flow valve plate. The first air flow valve plate is slidably arranged in the surrounding plate. After being lifted, the first channel is communicated with the second channel. After being lowered, the first channel is closed with the second channel.

[0009] Furthermore, the diversion holes are arranged in an array on the first air flow valve plate and the second air flow valve plates.

[0010] Furthermore, a heat exchanger is arranged in the second channel, and an air change fan is arranged in the second channel.

[0011] Furthermore, a driving mechanism is arranged on the upper part of the heat storage tank. The driving mechanism is in transmission connection with the upper end of the first air flow valve plate so that the first air flow valve plate can move up and down.

[0012] Furthermore, the driving mechanism includes a driving motor, a first gear arranged at the power output end of the driving motor, and teeth arranged on the first air flow valve plate for meshing with the first gear.

[0013] Furthermore, the first air flow valve plates are arranged at both ends on the same side.

[0014] In this steam generator heat storage device, a first air flow valve plate is provided. Through the lifting of the first air flow valve plate, the conduction and closing of the first channel and the second channel are realized. After conduction, heat exchange of the heat exchanger is realized through the air flow channel, so as to convert thermal energy into the thermal energy of the water medium in the heat exchanger, thereby realizing the storage of electric energy during low power consumption periods for use during peak periods. When heat release is not required, by closing the first channel and the second channel, a sealed heat insulation chamber is formed to store the heat of the storage cabinet without flowing out. This steam generator heat storage device realizes the conduction and closing of the air flow channel through the lifting of the first air flow valve plate, realizes heat exchange with the heat exchanger and heat insulation, and has a simple structure and convenient operation.

In this embodiment, the guide holes 8 are arranged in an array on the first airflow valve plate 4 and the second airflow valve plate 7.
