Description

Technical Field

[0001] The invention belongs to the technical field of industrial boilers, and in particular relates to an energy-saving treatment device for incineration waste gas from an industrial boiler. Background Art

[0002] Industrial boiler incineration waste gas refers to the gas emissions produced when the fuel is not completely burned or after combustion during the boiler combustion process. These waste gases usually contain smoke, sulfur dioxide, nitrogen oxides, carbon dioxide and some other possible harmful substances. The harmful substances in industrial boiler incineration waste gas will pollute the atmospheric environment and cause environmental problems such as acid rain and photochemical smog. Smoke and other particulate matter will also pollute the air, affect air quality, and pose a threat to human health. Waste gas usually contains a large amount of underutilized heat energy. Through energy-saving treatment, such as flue gas waste heat recovery, this part of the heat energy can be recovered and used for preheating boiler water, power generation or other heat energy utilization, thereby improving energy utilization efficiency.

[0003] For example, the national patent publication number CN111351058A discloses an energy-saving treatment device for industrial boiler incineration waste gas, which includes an incinerator, a balancing base, an exhaust port, a flue, a condenser, a water inlet, a water outlet, a waste gas treatment mechanism and a smoke outlet. A balancing base is installed at the bottom of the incinerator, the top upper end of the incinerator is fixedly connected with the exhaust port, the upper end of the exhaust port is connected with the flue, a condenser is sleeved on the outer wall of the bottom end of the flue, the left lower end of the condenser is connected with the water inlet, and the right upper end is connected with the water outlet, a waste gas treatment mechanism is arranged at the upper end of the inner cavity of the flue, and the top of the flue is connected with the smoke outlet, the waste gas treatment mechanism includes a microporous filter, a sponge adsorption network, a purification chamber, a nano photocatalyst network, a diatom adsorption filter layer and an activated carbon filter layer, and the microporous filter is fixedly installed in the inner cavity of the flue; it can not only treat the flue gas discharged from the boiler incineration, but also recover and reuse the energy in the flue gas.

[0004] However, the conventional device still has the following problems when used:

[0005] In the above device, the condenser is sleeved on the outer wall of the flue, and the condenser drives the flue gas to cool down quickly and condense into solid particles, so that the solid particles are deposited back into the incinerator for further incineration. However, due to the sleeve installation method of the condenser in the prior art, when the flue is cooled, the outer layer of the flue is directly attached to the condenser tube, and the temperature will drop rapidly, while the high temperature rising flow rate of the center layer of the flue due to the incinerator will be faster than the low temperature flow rate of the outer layer. Therefore, it is difficult to adjust the heat exchange balance of the condenser tube. Low heat exchange power will lead to incomplete waste gas treatment in the center layer of the flue, while increasing the heat exchange power will cause the waste gas in the outer layer to be over-cooled and condensed into solid particles so as to adhere to the inner wall of the smoke layer. Excessive adhesion and deposition will further affect the heat exchange efficiency of the condenser tube, and the waste gas is difficult to be fully treated. Therefore, the existing waste gas treatment device needs to be improved. Summary of the invention

In addition, when the brake blade 8 rotates, it will synchronously drive the first magnet strip 10 to scrape the inner wall of the flue 4, scraping off the solid particles adhered and deposited on the inner wall of the flue 4 and dropping them into the incinerator 1 below for re-incineration, so that the exhaust gas is further fully treated. At the same time, the condensed water in the condenser 5 is affected by the flue 4. Due to the influence of the close heat exchange, the temperature of the condensed water on the side close to the flue 4 will be relatively higher. In the present invention, the brake blade 8 drives the first magnet bar 10 to rotate. Affected by the magnetic adsorption of the first magnet bar 10 and the second magnet bar 28, when the first magnet bar 10 passes through the side wall of the second magnet bar 28, the adsorption trajectory will drive the second magnet bar 28 to make a small rotation with the transmission rod 26 as the axis. This rotation effect is used to accelerate the flow of condensed water in the condenser 5 by disturbing the fan plate 27, and replace part of the condensed water close to the flue 4 and the heat exchange plate 40, thereby accelerating the heat exchange efficiency and further improving the full treatment of the exhaust gas.

[0042] Embodiment 3, on the basis of embodiment 1, the outer wall of the outer connecting sleeve 6 is provided with a movable hole 12 connected at both ends, the inner wall of the movable hole 12 is movably connected with an inner adjusting sleeve 21, the inner adjusting sleeve 21 is located on one side of the outer wall in the flue 4 and is fixedly connected with a mounting ring plate 13, the outer wall of the mounting ring plate 13 is fixedly connected with a plurality of sub-brackets 14, the sub-brackets 14 and the fixing seat 7 are synchronously distributed in an array, an extension plate 15 is provided on the outer wall of one end of the sub-bracket 14 away from the mounting ring plate 13, connecting hinges 17 are installed on the outer walls of both ends of the extension plate 15, an adjusting block 16 is fixedly connected to the outer wall of one side of the fixing seat 7, the outer wall of one end of the extension plate 15 is hinged to the outer wall of the sub-bracket 14 through the connecting hinge 17, the outer wall of the other end of the extension plate 15 is hinged to the outer wall of the adjusting block 16 through the connecting hinge 17, the protective working box 23 is also fixedly connected with a vertical motor 22 through the mounting frame 24, the vertical The output shaft of the linear motor 22 is fixedly connected to the outer wall of one side of the inner adjustment sleeve 21, the inner wall of the flue 4 is fixedly connected to a placement box 29, the bottom inner wall of the placement box 29 is rotatably connected to a supporting base 34, the top outer wall of the supporting base 34 is fixedly connected to two sleeve rods 35, the outer wall of the sleeve rod 35 is fixedly connected to a scraping rod 36, the outer walls of the two scraping rods 36 are movably fitted with the outer walls of the brake blades 8, the high-temperature resistant rubber gasket 9, and the first magnet strip 10, the outer wall of one side of the placement box 29 is fixedly connected to a running motor 32, the axis of the running motor 32 is fixedly connected to a connecting shaft 33, the connecting shaft 33 passes through the placement box 29 and is fixedly connected to the outer wall of the supporting base 34, spring hinges 30 are fixedly installed on the inner walls of both sides of the placement box 29, and a protective baffle 31 is fixedly connected to the outer wall of one side of the spring hinge 30, and the protective baffle 31 is hinged to the placement box 29 through the spring hinge 30.

[0043] Since the brake blades 8, high temperature resistant rubber gaskets 9 and the first magnet strip 10 are in the exhaust gas environment during operation, the outer wall is also prone to solid particles. In the present invention, the vertical motor 22 is started to drive the inner adjustment sleeve 21 to move on the inner wall of the outer connecting sleeve 6, and further drives the mounting ring plate 13 to move. Through the hinge of the extension plate 15, the mounting ring plate 13 is moved forward and backward, and one end of the adjustment block 16 is synchronously pulled, so that the adjustment block 16 is used to drive the brake blades 8 to rotate 45° with the fixed seat 7 as the axis, so that the blade surfaces of multiple brake blades 8 are adjusted to a vertical state and in the same plane, and then the running motor 32 is started to drive the scraper rod 36 to rotate with the connecting shaft 33 as the axis to separate from the cavity of the placement box 29 and present a completely horizontal state.

[0044] Working principle and use process of the present invention: In the present invention, the power furnace 2 provides combustion power to incinerate the exhaust gas in the incinerator 1. When the exhaust gas is subjected to the high temperature of incineration and rises through the flue 4, the flue 4 is cooled by the condenser 5 to condense the rising exhaust gas into solid particles and return to the furnace for further incineration. At this time, the overall heat exchange efficiency of the outer circle layer and the central circle layer in the flue 4 is not synchronized. Therefore, in the present invention, by starting the brake motor 20 in the protective working box 23, the gear 2 19 drives the gear 1 18 to engage and rotate, and the rotation of the gear 1 18 synchronously drives the external connecting sleeve 6 to rotate, and further drives the brake blades 8 to rotate with the external connecting sleeve 6 as the axis to generate wind flow, disrupting the direct rising airflow of the exhaust gas, and the outer circle layer of cooling air and the inner circle layer of high-temperature air in the flue 4. Mixing, thereby improving the heat exchange efficiency, and further fully treating the exhaust gas. In the present invention, a spoiler groove 11 with a V-shaped cross-section is opened on the high-temperature resistant rubber gasket 9, so that the brake blade 8 drives the high-temperature resistant rubber gasket 9 to rotate synchronously when rotating, and the rotating air is squeezed through the V-shaped cross-section, further disrupting the wind flow, thereby improving the heat exchange efficiency, and further fully treating the exhaust gas. In addition, when the brake blade 8 rotates, it will synchronously drive the first magnet bar 10 to scrape the inner wall of the flue 4, scrape off the solid particles adhered to and deposited on the inner wall of the flue 4 and drop them into the incinerator 1 below to be re-incinerated, so that the exhaust gas is further fully treated. At the same time, the condensed water in the condenser 5 is affected by the close heat exchange of the flue 4, and the condensed water temperature close to the flue 4 side is The degree will be relatively higher. In the present invention, the brake blade 8 drives the first magnet strip 10 to rotate. Affected by the magnetic attraction of the first magnet strip 10 and the second magnet strip 28, when the first magnet strip 10 passes through the side wall of the second magnet strip 28, the adsorption trajectory will drive the second magnet strip 28 to rotate slightly with the transmission rod 26 as the axis. The fan plate 27 is used to accelerate the flow of condensed water in the disturbance condenser 5, and replace part of the condensed water close to the flue 4 and the heat exchange plate 40, thereby accelerating the heat exchange efficiency and further improving the full treatment of the exhaust gas. Since the brake blade 8, the high temperature resistant rubber gasket 9 and the first magnet strip 10 are in the exhaust gas environment during operation, the outer wall is also prone to adherence to solid particles. In the present invention, by starting the vertical The motor 22 drives the inner adjustment sleeve 21 to move on the inner wall of the outer connecting sleeve 6, and further drives the installation ring plate 13 to move. Through the hinge of the extension plate 15, the installation ring plate 13 is moved forward and backward, and one end of the adjustment block 16 is synchronously pulled, so that the adjustment block 16 is used to drive the brake blade 8 to rotate 45 degrees with the fixed seat 7 as the axis, so that the blade surfaces of multiple brake blades 8 are adjusted to a vertical state and in the same plane, and then the operation motor 32 is started to drive the scraper rod 36 to rotate with the connecting shaft 33 as the axis to separate from the cavity of the placement box 29 and present a completely horizontal state. At this time, the rotation speed of the brake blade 8 is controlled. When the brake blade 8 rotates, it will pass through the gap between the two scraper rods 36, so that the scraper rod 36 is used to scrape the solid particles adhered to the outer wall of the lower brake blade 8.Since the included angle between the high temperature resistant rubber gasket 9 and the brake blade 8 is 120° and it has the characteristics of deformation rebound, it can drive the first magnet strip 10 to synchronously follow the brake blade 8 through the gap of the scraper rod 36. The solid particles adhering to the outer wall of the brake blade 8, the high temperature resistant rubber gasket 9 and the first magnet strip 10 are processed by this device, and the protective baffle 31 can be actively closed after the scraper rod 36 passes through due to the resilience of the spring hinge 30, so that when the scraper rod 36 is placed in the placement box 29, it can prevent the exhaust gas from flowing into the placement box 29, providing protection for the scraper rod 36.
