Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery, in particular to a heat storage type combustion exhaust gas waste heat recovery device. Background Art

[0002] Waste heat refers to the usable heat energy released during the production process, mainly high-temperature exhaust gas. Most existing companies purify high-temperature exhaust gas and then discharge it directly into the atmosphere, resulting in a large amount of heat energy waste.

[0003] For example, a waste heat recovery device for a thermal storage incinerator (Announcement No.: CN218763430U) includes a furnace body, a heat storage tank fixedly connected to the middle of the inner wall of the furnace body, a water storage tank 2 fixedly connected to the upper side of the heat storage tank, and the upper part of the heat storage tank is open, and a burner is fixedly connected to the middle of the left and right walls inside the heat storage tank. By arranging the heat storage tank, the water storage tank 2, the burner, the conduit, the water storage tank 1, and the temperature detector 2, the burner is turned on in advance to preheat the inside of the heat storage tank, and the temperature detector 2 detects the preheating temperature. After the temperature reaches the standard, the exhaust gas is discharged into the heat storage tank, and the exhaust gas is incinerated by the burner. The heat generated during the incineration of the exhaust gas directly heats the water inside the water storage tank 2, and the generated carbon dioxide flows into the water storage tank 1 through the conduit. At the same time, the carbon dioxide has a certain temperature. After being discharged into the water storage tank 1, the water stored in the water storage tank 1 is heated.

[0004] When the device is in use, the water inside the water tank 2 is dead water. When the water inside the water tank 2 is heated, the water is heated unevenly. The water inside the water tank 2 heats up relatively slowly, which reduces the utilization efficiency of the waste heat of the exhaust gas. Therefore, we need to propose a heat storage type combustion waste heat recovery device. Utility Model Content
