Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, and in particular to an energy-saving and emission-reducing waste heat flue gas recovery device. Background Technology

[0002] In industrial production and energy utilization processes such as metallurgy, chemicals, power, and building materials, core processes such as boiler combustion, kiln smelting, and chemical reactions continuously generate large amounts of waste heat flue gas, typically ranging in temperature from 100-800℃, carrying a significant amount of low-grade heat energy. Direct emission of this flue gas causes severe thermal pollution, exacerbating regional environmental warming; furthermore, the dust, SO2, and NO contained in the flue gas contribute to pollution. x Pollutants such as these can damage the atmospheric ecosystem and harm human health. At the same time, the waste of a large amount of recoverable heat energy leads to low energy utilization efficiency, which contradicts the current industrial demand for energy conservation, carbon reduction, and green development, and has become a prominent problem restricting the sustainable development of industry.

[0003] Patent CN214865904U discloses an environmentally friendly, energy-saving, and emission-reducing waste heat and flue gas recovery device, including a main body. In this invention, a motor drives a reducer to rotate, which in turn drives a connecting shaft to rotate. The connecting shaft then drives a rotating rod to rotate, causing a first connecting rod to rotate. This rotation allows two sets of first brushes to clean the inner wall of the waste heat collection box. Furthermore, the rotation of the first connecting rod also drives a second connecting rod to rotate around the rotating rod, allowing two sets of second brushes to clean the top of the waste heat collection box, as well as the first and second heat-conducting blocks. In this invention, external water is delivered through a first water injection pipe to a first flushing head, and then sprayed out from the first flushing head to wash the inside of the waste heat collection box, further enhancing the cleaning effect.

[0004] However, the device has low heat recovery efficiency for waste flue gas, and uneven absorption of waste heat results in high and uneven flue gas temperature entering the filter box, causing heat waste and even harming the surrounding environment due to incomplete cooling of the discharged flue gas. Secondly, the device's built-in cleaning function has blind spots, still requiring manual cleaning by operators, which affects cleaning efficiency. Furthermore, the device uses a large number of mechanical parts located inside the device for extended periods. Under the harsh working environment inside the device, these mechanical parts are prone to failure, affecting work efficiency. Utility Model Content

[0005] In view of the above technical problems, this utility model provides an energy-saving and emission-reducing waste heat flue gas recovery device that can efficiently recover waste heat.

[0006] This utility model provides an energy-saving and emission-reducing waste heat flue gas recovery device, characterized in that it includes a filter box, a filter unit, fixing screws, a heat dissipation plate, a heat dissipation plate mounting base, a heat absorption box, fixing nuts, and a connecting plate. The filter unit is symmetrically installed on the left and right sides of the filter box by fixing screws and fixing nuts. The filter box is fixedly connected to the heat absorption box by the connecting plate. Heat dissipation plate mounting bases are installed on the left and right sides of the heat absorption box by fixing nuts and fixing screws. The heat dissipation plate mounting bases are fixedly connected to a plurality of heat dissipation plates. The plurality of heat dissipation plates extend through the heat dissipation plate mounting bases into the heat absorption box and are movably connected to the heat absorption box.

[0007] The filter box includes a filter box body, an upper fixed plate A, a sealing strip A, a lower fixed plate A, a first output connector, a valve A, and a second output connector. The upper fixed plate A is symmetrically fixed to one side of the top of the filter box body. The first output connector and the second output connector are symmetrically fixed to the upper front of the filter box body. The first output connector and the second output connector are connected via valve A, which is fixedly connected to the filter box body. The lower fixed plate A is symmetrically fixed to the lower front of the filter box body. The rear side of the filter box body is fixedly connected to the heat absorption box via a connecting plate. The internal part of the filter box body is divided into two independent compartments. An air inlet is provided on the rear inner wall of the filter box body, and several air outlets are provided on the front inner wall of the filter box body. (Note: The purpose of this heat dissipation box is not described later. The name was changed once during writing; it was initially called a heat dissipation box, but later changed to a heat absorption box. The "heat dissipation box" part was an oversight and not consistent.)

[0008] The filter unit includes a filter plate mounting base, a raised fixing plate, a filter plate, an upper fixing plate B, and a lower fixing plate B. The upper fixing plate B is symmetrically fixedly connected to the top of the filter plate mounting base. The raised fixing plate and the lower fixing plate B are fixedly connected to the front and rear sides of the filter plate mounting base, respectively. Several filter plates are connected to one side of the filter plate mounting base.

[0009] The top of the heat sink mounting base is symmetrically fixedly connected to an upper fixing plate C, and the front and rear sides of the heat sink mounting base are symmetrically fixedly connected to a lower fixing plate C.

[0010] The heat absorption box includes a heat absorption box body, a sealing strip B, a lower fixing plate D, a second input connector, a valve B, a first input connector, and an upper fixing plate D. The upper fixing plate D is symmetrically fixedly connected to one side of the top of the heat absorption box body. The first input connector and the second input connector are symmetrically fixedly connected to the upper rear side of the heat absorption box body. The first input connector and the second input connector are connected through the valve B, which is fixedly connected to the heat absorption box body. The lower fixing plate D is symmetrically fixedly connected to the lower rear side of the heat absorption box body. The heat absorption box body is divided into two independent compartments. Several heat dissipation plate connecting grooves are provided on the inner walls of both compartments. The heat dissipation plate connecting grooves are slidably connected to the heat dissipation plates. Heat absorption box air outlets are symmetrically provided on the front inner wall of the heat absorption box body. Several heat absorption box air inlets are provided on the rear inner wall of the heat absorption box body.

[0011] The beneficial effects of this utility model are as follows: By combining several heat dissipation plates and the heat absorption box body, the transport route of the waste heat flue gas in the heat absorption box is restricted to a serpentine route, which extends the travel distance of the waste heat flue gas in the heat absorption box, so that the heat dissipation plates can fully absorb the residual heat in the waste heat flue gas. Users can connect the device or medium that needs to absorb residual heat to the part of the heat dissipation plate that extends out of the heat absorption box, thereby achieving the purpose of energy saving.

[0012] By making the heat sink and filter plate detachable, the device eliminates the need for complex internal mechanical devices and control systems. When cleaning is required, only the heat sink and filter plate mounting bases need to be removed, and the operator can manually or with the help of cleaning equipment clean the heat sink, filter plate, and the inside of the device. This avoids cleaning dead spots, improves the reliability of the device, and reduces production costs.

[0013] The independent compartments, consisting of valves A and B, as well as the heat absorption box and filter box, allow the device to treat two different types of waste heat flue gas simultaneously. Alternatively, the same type of waste heat flue gas can be treated by two independent compartments through the control of valves A and B. This structure improves the applicability of the device and reduces production costs. Attached Figure Description
