Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of boiler flue gas waste heat utilization, in particular to a boiler flue gas waste heat utilization device. Background Art
[0002] A boiler is a heat exchange device that uses the thermal energy of fuel or other energy sources to heat a working medium (usually purified water) to certain parameters (temperature, pressure). The task of a boiler is to safely, reliably, and economically convert the chemical energy of the fuel into thermal energy, and then transfer the thermal energy to water to produce hot water or steam; or transfer the chemical energy of the fuel to other working media, such as heat transfer oil, to produce other high-temperature working media, such as high-temperature heat transfer oil.
[0003] The existing boiler flue gas waste heat utilization device is usually composed of a water tank and a serpentine pipe. The serpentine pipe is placed in the water tank. Cold water is contained in the water tank. Flue gas is passed into the serpentine pipe, and the heat of the flue gas is transferred to the serpentine pipe, which heats the cold water again. In this way, the waste heat of the boiler flue gas can be utilized. However, the boiler flue gas contains smoke dust. The serpentine pipe will adhere to thick smoke dust inside if the flue gas is conducted for a long time, which will reduce the thermal conductivity of the serpentine pipe. Therefore, the inside of the serpentine pipe needs to be cleaned after using it for a period of time. However, the shape of the serpentine pipe is relatively special. Only the two ends of the pipe are provided with openings, and the rest of the parts are closed structures. This makes it inconvenient to clean the inner wall of the serpentine pipe. Therefore, when maintaining the boiler flue gas waste heat utilization device, the serpentine pipe is often directly replaced, which will greatly increase the maintenance cost of the boiler flue gas waste heat utilization device. In view of the above problems, we have introduced a boiler flue gas waste heat utilization device. Utility Model Content

[0021] The utility model discloses a boiler flue gas waste heat utilization device which is mainly used in the scenario of boiler flue gas waste heat utilization.
[0022] Reference Figure 1 and Figure 2 A boiler flue gas waste heat utilization device comprises: a water tank 1, support frames 2 are fixedly connected to both sides of the water tank 1, a slot is opened on one side of the water tank 1, a heat conduction component is fixedly connected to the inside of the water tank 1, a water inlet 6, a water outlet 7 and an air inlet 9 are respectively arranged on one side of the water tank 1, an air outlet 5 is equidistantly arranged on the top of the water tank 1, a discharge port 8 is fixedly connected to the bottom of the water tank 1, mounting plates 12 are fixedly connected to both sides of the inner wall of the water tank 1, a filter plate 13 is slidably connected between the top and the bottom of the mounting plate 12, a box door 3 is rotatably connected to one side of the water tank 1, a handle 26 is arranged on one side of the box door 3, two shells 15 are equidistantly fixedly connected to one side of the water tank 1, and fixed components are arranged inside the two shells 15.
[0023] In the above technical scheme, it is taken into account that the boiler flue gas contains smoke and dust, and the serpentine tube conducts smoke for a long time, which will cause thick smoke and dust to adhere to the inside and is difficult to clean. In order to solve such problems, the specific operations are as follows: By setting a filter plate 13, the boiler flue gas entering the water tank 1 can be filtered, and then the filtered gas is transported to the heat conduction component for waste heat utilization, thereby heating the cold water in the water tank 1. Since the filter plate 13 filters smoke and dust for a long time, it may be blocked and affect the filtering effect, so it needs to be disassembled and cleaned. By setting a fixed component, the box door 3 can be quickly opened and closed, so that the internal filter plate 13 can be conveniently removed from the water tank 1 for cleaning, thereby reducing maintenance and cleaning time.
[0024] Reference Figure 3 and Figure 4 In a preferred embodiment, the fixing assembly includes a groove 16, which is provided inside the housing 15, and a slider 17 is slidably connected inside the groove 16, and a block 18 is fixedly connected to one side of the slider 17. A groove 19 is provided on one side of the door 3, and one side of the block 18 conflicts with one side of the inner wall of the groove 19. A spring 20 is provided between one side of the block 18 and one side of the inner wall of the groove 16. A slide groove 23 is provided on the top of the slider 17, and a connecting rod 21 is provided on one side of the housing 15. One end of the connecting rod 21 extends to the inside of the slide groove 23 and is fixedly connected to a slide rod 22. The outer side of the slide rod 22 is slidably connected to the inside of the slide groove 23, and one end of the connecting rod 21 is fixedly connected to a connecting block 24. A slope is provided on one side of the block 18, and a groove 25 is provided on one side of the door 3, and a sealing ring is provided inside the groove 25.
[0025] In the above technical solution, the problem of clogging of the filter plate 13 is taken into consideration. In order to solve this problem, the specific operation is as follows: press the connecting block 24 by hand, and drive the connecting rod 21 and the sliding rod 22 to move toward the inside of the container 16 under the action of force, thereby driving the slider 17 and the card block 18 to move toward one side of the inner wall of the container 16, and finally allowing the card block 18 to be disengaged from the inside of the card slot 19, so that the box door 3 can be opened, and then the filter plate 13 can be taken out for cleaning. After cleaning, the filter plate 13 is placed into the water storage tank 1 through the track of the mounting plate 12, and then the box door 3 is closed. When the corners of the box door 3 are aligned with the card block 1 8, the block 18 is pushed to move toward the inside of the groove 16 again under the action of force. At this time, the spring 20 is in a compressed state. When the block 18 is staggered with the door 3, the door 3 is completely closed. Under the action of the spring 20, the block 18 is driven to re-enter the groove 19, and then the door 3 is fixed again. The operation is simple and the filter plate 13 can be disassembled and cleaned conveniently. Regular cleaning of the filter plate 13 can maintain its filtering effect and avoid clogging that affects the filtering efficiency. By arranging a sealing ring inside the groove 25, the sealing of the door 3 can be ensured to prevent ash leakage and affect the environment.
[0026] Reference Figure 2 In a preferred embodiment, the heat conduction component includes a sealing cover 10, which is fixedly connected to the inside of the water tank 1. Two connecting pipes 11 are respectively arranged on the top of the sealing cover 10. One end of the two connecting pipes 11 is fixedly connected to a serpentine pipe 4, and the top of the serpentine pipe 4 is fixedly connected to the air outlet 5. After filtering the smoke entering the water tank 1, the filtered gas enters the sealing cover 10, and then enters the connecting pipe 11 and the serpentine pipe 4, so as to heat the cold water in the water tank 1, thereby achieving the effect of utilizing the waste heat of the boiler flue gas.
[0027] Reference Figure 2 In a preferred embodiment, placement grooves 14 are equidistantly provided on one side of the filter plate 13, and activated carbon filling bags are arranged inside the placement grooves 14; by arranging the activated carbon filling bags, harmful substances in the smoke can be adsorbed. The activated carbon has a highly porous structure and can provide a large amount of adsorption surface area, which can effectively adsorb harmful substances in the smoke and further improve the effect of the filter plate 13 on filtering smoke.
[0028] Working principle: When in use, first fill the water storage tank 1 through the water inlet 6, then connect the boiler to the air inlet 9 of the water storage tank 1 through a pipe, and transport the flue gas. The flue gas floats upward in the water storage tank 1, passes through the filter plate 13, and is filtered under the action of the filter plate 13 and the activated carbon filling bag. The filtered gas continues to rise and enters the sealing cover 10, and then enters the connecting pipe 11 and the serpentine pipe 4. The water will absorb the heat carried by the gas, thereby achieving the heating effect. Finally, the gas will be discharged through the outlet 5. When the filter plate 13 needs to be cleaned, press the connecting block 24 by hand, and drive the connecting rod 21 and the sliding rod 22 to move toward the inside of the container 16 under the action of force, thereby driving the slider 17 and the block 18 to move to one side of the inner wall of the container 16, and finally Finally, the block 18 is disengaged from the inside of the slot 19, and the box door 3 can be opened, and the filter plate 13 can be taken out for cleaning. After cleaning, the filter plate 13 is placed in the water storage tank 1 through the track of the mounting plate 12, and then the box door 3 is closed. When the corner of the box door 3 conflicts with the inclined surface of the block 18, the block 18 is pushed to move toward the inside of the containing groove 16 again under the action of the force. At this time, the spring 20 is in a compressed state. When the block 18 and the box door 3 are staggered, the box door 3 is completely closed. Under the action of the spring 20, the block 18 is driven to re-enter the slot 19, and then the box door 3 is fixed again, and then the smoke and dust are continued to be filtered. The operation is simple and convenient. The contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.
