Description

Technical Field

[0001] The present invention belongs to the field of heat storage and energy-saving technology, and specifically relates to a movable heat storage and energy-saving system that utilizes industrial waste heat to provide heating energy. Background Art

[0002] Industrial waste heat refers to the residual heat generated during the industrial production process, such as cement, steel, thermal power, ceramics, non-ferrous metals, etc. Its characteristics include multi-form, dispersion and uneven distribution in different industries. According to the energy source, industrial waste heat can be divided into multiple types, such as high-temperature flue gas waste heat, cooling medium waste heat, waste water and waste steam waste heat. One of the main methods of current energy storage is to convert it into electrical energy storage. Electricity is a primary energy source and can be converted into a variety of energy sources. It has obvious advantages, but the storage cost of electrical energy is very high compared to heat, which is more than ten to twenty times that of thermal energy storage. The present invention mainly focuses on the recovery of industrial waste heat and proposes a heat storage device for storing heat, using heat storage instead of electricity storage.

[0003] However, common industrial waste heat energy storage devices are too large and difficult to move. Summary of the Invention

[0004] The purpose of the present invention is to provide a movable heat storage and energy-saving system that utilizes industrial waste heat to provide heating energy in order to solve the problem that the above-mentioned equipment is too large and inconvenient to move.

[0005] The technical solution adopted in the present invention is as follows:

[0006] A movable heat storage and energy-saving system that utilizes industrial waste heat for heating energy includes a heat storage device, a heat storage tank is fixedly installed inside the heat storage device, an auxiliary leakage plate is fixedly installed inside the heat storage tank, and a heat-absorbing ball is placed on the top of the auxiliary leakage plate.

[0007] By adopting the above technical solution, this structure designs a heat storage device specifically for storing industrial waste heat. Multiple heat storage tanks are set up inside the device. The heat storage tanks are used to store the heat generated by high-temperature waste heat fluid. The storage method is that the waste heat fluid heats cold water through a heat exchanger, and the heated hot water is passed into the tank for storage. An auxiliary leakage tray and heat-absorbing beads are set up at the upper part of the interior of the heat storage tank. The position of the heat-absorbing beads is fixed by the leakage tray and the heat-absorbing beads are used to assist in storing more heat energy. When heat energy is needed, the outlet at the bottom is opened, and cold water is added to output the hot water at the top and release the heat energy through the heat exchanger.

[0008] In a preferred embodiment, a fixed layer is provided inside the heat storage device, and a pulley is fixedly installed on the bottom of the heat storage device.

[0009] By adopting the above technical solution, this structure is wrapped with a fixed layer on the periphery of the middle area of ​​the heat storage tank, providing a certain support capacity to prevent the heat storage tank from moving during transportation and causing damage to the tank body. Pulleys are set at the bottom to help the entire heat storage equipment move better and be used smoothly.

[0010] In a preferred embodiment, a buffer tray is placed on the bottom side of the heat storage tank.

[0011] By adopting the above technical solution, this structure sets up two buffer plates in the bottom curvature area of ​​the heat storage tank to protect the heat storage tank from bumps encountered during transportation and avoid damage to the bottom pipeline caused by collisions with the bottom of the tank.

[0012] In a preferred embodiment, a heat exchanger is fixedly mounted on the top of the heat storage tank, an air pipe is fixedly mounted on the top of the heat exchanger, a heat storage inlet is connected to the front of the heat exchanger, and a cold liquid outlet is set up at the bottom of the heat storage tank.

[0013] By adopting the above technical solution, this structure designs an inlet at the top of the heat storage tank. When storing heat energy, the industrial waste heat gas is heated by the heater to generate hot water, which is introduced into the tank through the inlet for storage. An equal amount of cold water is discharged from the bottom outlet to leave space. When heat energy is needed, cold water is added from the bottom outlet to discharge the hot water at the top inlet and connect to the calorifier to export the heat energy.

[0014] In a preferred embodiment, a water collecting pan is fixedly connected to the bottom of the cold liquid outlet, and a control valve is installed on the front of the water collecting pan.

[0015] By adopting the above technical solution, this structure connects the water collection tray and the control valve at the bottom of the outlet of multiple heat storage tanks, which is used to handle the discharge of cold water when multiple heat storage tanks are storing heat, making it convenient to uniformly collect cold water and reuse it when heat energy is needed next time, thereby reducing waste.

[0016] In a preferred embodiment, a drain port is provided on the side of the water collecting tray.

[0017] By adopting the above technical solution, the structure sets up a drain port on the side of the water collecting tray to facilitate the discharge and secondary use of cold water.

[0018] In a preferred embodiment, a side surface of the cold liquid outlet is connected to a cold liquid input box, and a cold liquid input port is fixedly mounted on the front surface of the cold liquid input box.

[0019] By adopting the above technical solution, this structure installs an input box on the side of the cold liquid outlet and provides an input port on the front of the input box. When releasing heat, cold water is added through the input port to discharge the hot water on the top of the heat storage tank to complete the heat release.

[0020] In a preferred embodiment, a turbulent layer is provided inside the heat storage tank.

[0021] By adopting the above technical solution, this structure sets a turbulence layer similar to an hourglass in the middle part of the heat storage tank to slow down the contact between the hot water at the top and the cold water at the bottom, avoiding excessive heat transfer to the cold water, resulting in cooling and inability to concentrate heat storage.

[0022] In a preferred embodiment, a heat-insulating layer is provided on the outside of the heat storage tank.

[0023] By adopting the above technical solution, this structure establishes a thermal insulation layer on the outside of the heat storage tank, which assists the heat storage tank in retaining heat and provides a certain degree of protection.

[0024] In a preferred embodiment, a leakage hole is provided inside the auxiliary leakage disk.

[0025] By adopting the above technical solution, this structure sets up a leakage hole in the auxiliary leakage tray of the heat storage tank. The size of the leakage hole is smaller than the heat-absorbing ball above it, so as to prevent the heat-absorbing ball from falling from the auxiliary leakage tray to the bottom of the heat storage tank. Secondly, due to the design of the hole, the contact between the hot water on the top layer and the hot water at the bottom is slowed down, so that the temperature can be better preserved, avoiding rapid cooling in the heat storage tank, which makes the waste heat energy unusable for cooling.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] The present invention designs a heat storage device specifically for storing industrial waste heat. Multiple heat storage tanks are installed inside the device. These tanks are used to store heat generated by high-temperature waste heat fluid. The storage method involves heating cold water through a heat exchanger, which is then passed into the tank for storage. An auxiliary drain pan and heat-absorbing beads are installed at the upper portion of the heat storage tank. The drain pan secures the position of the heat-absorbing beads and assists in storing more heat energy. When heat energy is needed, the bottom outlet is opened, cold water is added, and the hot water at the top is output and released through the heat exchanger. Because the storage tanks of this structural design are all relatively thin, the overall weight of the heat storage device is relatively light. Furthermore, the heat storage tanks are detachable and can be used individually, further reducing the overall weight. Rollers at the bottom facilitate transportation. Furthermore, protective measures are implemented within the heat storage device to prevent damage during transportation and protect the integrity of the device. BRIEF DESCRIPTION OF THE DRAWINGS
