Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically a lithium bromide heating waste heat recovery device. Background Technology

[0002] The main purpose of lithium bromide heating waste heat recovery devices is to efficiently recover the heat from waste gases generated by boilers or other industrial equipment and use this heat to heat lithium bromide solutions, thereby improving energy efficiency and reducing overall energy consumption.

[0003] In current lithium bromide waste heat recovery systems, the heat from the waste gas is commonly used to heat the lithium bromide. However, since the waste gas often contains a lot of impurities, if these impurities are discharged directly without effective cleaning, they will cause potential damage to the heat exchanger when it passes through it. These impurities may not only cause corrosion and wear of the heat exchanger, but may also accumulate inside the heat exchanger, causing blockage, seriously affecting the heat exchange effect of the heat exchanger, and reducing the efficiency of the overall heating and recovery system. Utility Model Content

[0006] Support rods are fixed to the four corners of the top of the base plate. A recycling bin is fixedly connected to the top of the support rod. Both sides of the top of the recycling bin are rotatably connected to a sealing cover via hinges. A gas furnace is fixedly connected to the top of the base plate. Filter assemblies are provided on both sides of the gas furnace. The filter assemblies include a conveying pipe and a filter plate.

[0007] A lithium bromide assembly is installed inside the recovery tank, the lithium bromide assembly including a heat exchanger and a lithium bromide generator.

[0009] Preferably, an activated carbon plate for enhanced filtration of exhaust gas is fixedly connected to the surface of the filter plate.

[0010] Preferably, the recycling bin has grooves on both sides, and sliders are fixedly connected to both sides of the filter plate, with the surfaces of the sliders inserted into the inner cavity of the grooves.

[0013] Preferably, a fixing sleeve is inserted into the surface of the conveying pipe, and the surface of the fixing sleeve is fixedly connected to the recycling bin.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through the design of a filter assembly, firstly fixes the filter plate within the inner cavity of the slide groove using a slider. When the exhaust gas generated by the gas furnace needs to be filtered and recovered, the exhaust gas is first transported from inside the gas furnace through a conveying pipe, and then discharged into the inner cavity of the recovery box.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, a lithium bromide heating waste heat recovery device includes a base plate 1, and further includes:

[0023] Support rods 2 are fixed to the top four corners of the base plate 1. A recycling bin 3 is fixedly connected to the top of the support rods 2. Both sides of the top of the recycling bin 3 are connected to a sealing cover 4 by hinges. A gas furnace 5 is fixedly connected to the top of the base plate 1. Filter components 6 are provided on both sides of the gas furnace 5. The filter components 6 include a conveying pipe 601 and a filter plate 602.

[0024] Two conveying pipes 601 are connected to the flanges on both sides of the gas furnace 5 on opposite sides. The top of the conveying pipes 601 extends into the inner cavity of the recovery box 3. The surface of the filter plate 602 is set in the inner cavity of the recovery box 3. An activated carbon plate 603 for enhanced filtration of exhaust gas is fixedly connected to the surface of the filter plate 602. Slide grooves 8 are opened on both sides of the recovery box 3. Slider blocks 604 are fixedly connected to both sides of the filter plate 602. The surface of the sliders 604 is inserted into the inner cavity of the slide grooves 8. Guide plates 9 for guiding and conveying exhaust gas are fixedly connected to both sides of the top of the inner cavity of the recovery box 3. First, the filter plate 602 is fixed in the inner cavity of the slide groove 8 by inserting the sliders 604 into it. When the exhaust gas generated by the gas furnace 5 needs to be filtered and recovered, the exhaust gas is first transported from inside the gas furnace 5 through the conveying pipe 601, and then discharged into the inner cavity of the recovery box 3 through the conveying pipe 601. Subsequently, as the exhaust gas is discharged into the recovery box 3, the internal guide plate 9 guides the exhaust gas at the discharge angle and discharges it onto the surface of the filter plate 602. The filter plate 602 then filters and intercepts impurities in the exhaust gas. At the same time, the activated carbon plate 603 on the surface of the filter plate 602 further filters the impurities in the exhaust gas to ensure the cleanliness of the exhaust gas, thereby achieving the effect of filtering impurities in the exhaust gas.

[0025] The lithium bromide assembly 7 is located inside the recovery tank 3. The lithium bromide assembly 7 includes a heat exchanger 701 and a lithium bromide unit 702.

[0026] The bottom of heat exchanger 701 is fixedly connected to the inner cavity of recovery box 3, and the bottom of lithium bromide unit 702 is fixedly connected to heat exchanger 701. By setting heat exchanger 701 and lithium bromide unit 702 to be used together, heat in the exhaust gas can be easily collected, and the heat exchanger 701 can be used to transfer the heat to the surface of lithium bromide unit 702. Finally, the heat can be heated by lithium bromide unit 702.

[0027] A fixing sleeve 605 is inserted into the surface of the conveying pipe 601, and the surface of the fixing sleeve 605 is fixedly connected to the recycling box 3. By setting the fixing sleeve 605, the conveying pipe 601 can be positioned and secured while conveying waste gas, so as to avoid loosening later and affecting the conveying of waste gas.

[0028] Working principle: First, the gas furnace 5 heats and burns the gas. Then, the filter plate 602 is fixed in the inner cavity of the slide groove 8 by the slider 604. When the exhaust gas generated by the gas furnace 5 needs to be filtered and recovered, the exhaust gas is first transported from inside the gas furnace 5 through the conveying pipe 601, and then discharged into the inner cavity of the recovery box 3 through the conveying pipe 601. At the same time as the exhaust gas is discharged into the recovery box 3, the internal guide plate 9 guides the exhaust gas at the discharge angle and discharges it onto the surface of the filter plate 602. The filter plate 602 then filters and intercepts impurities in the exhaust gas. At the same time, the surface of the filter plate 602... The activated carbon plate 603 filters impurities in the exhaust gas again. The filtered exhaust gas is then transported to the surface of the heat exchanger 701, where heat is transferred to the cooled lithium bromide solution. During this process, the temperature of the exhaust gas gradually decreases, and latent heat is released through condensation. At the same time, the lithium bromide solution flows through the heat exchanger 701, absorbing the heat transferred from the exhaust gas. Due to the excellent heat absorption performance of the lithium bromide solution, it can rapidly increase the temperature, thereby effectively providing the required heat energy for the heating system. Through this process, the heat in the exhaust gas is effectively recovered, and the lithium bromide solution can reach the required heating temperature in a short time, ensuring the energy-saving and efficient operation of the lithium bromide unit 702.
