Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to an environmentally friendly integrated device for desulfurization, denitrification and dust removal of industrial waste gas. Background Technology

[0002] Industrial waste gas desulfurization and denitrification equipment is an indispensable environmental protection device in modern industrial production. It is mainly used to remove harmful gases such as sulfur oxides (SOx) and nitrogen oxides (NOx) from industrial waste gas.

[0003] A search revealed a waste gas desulfurization and denitrification device with authorization announcement number CN216856259U. This utility model incorporates a stirring mechanism that disperses waste gas into the treatment liquid and stirs the liquid. Traditional waste gas desulfurization and denitrification devices typically extract waste gas into the treatment liquid for processing. However, prolonged storage of the treatment liquid can lead to sedimentation or stratification, resulting in poor desulfurization and denitrification effects. This new device prevents sedimentation and stratification in the treatment liquid, thereby improving the desulfurization and denitrification effect of the waste gas within the treatment liquid.

[0004] However, during the use of the above-mentioned device, because the exhaust gas is not filtered before entering the treatment liquid, a large amount of dust will remain in the treatment liquid, causing dust pollution. When the pollution is severe, the treatment liquid needs to be replaced, which undoubtedly increases the cost of using the treatment liquid.

[0005] Therefore, it is necessary to provide an environmentally friendly integrated device for desulfurization, denitrification, and dust removal of industrial waste gas to solve the above-mentioned technical problems. Utility Model Content

[0006] To address the technical problem that existing industrial waste gas desulfurization and denitrification devices cause dust pollution to the treatment liquid due to the waste gas not being filtered before entering the treatment liquid, leading to frequent replacement of the treatment liquid and increased operating costs, this utility model provides an environmentally friendly integrated industrial waste gas desulfurization, denitrification, and dust removal device.

[0007] The environmentally friendly industrial waste gas desulfurization, denitrification, and dust removal integrated device provided by this utility model includes: a shell, in which a treatment liquid for desulfurizing and denitrifying industrial waste gas is provided; a diversion pipe is rotatably installed on the shell; multiple jet pipes and multiple stirring rods are fixedly installed on the diversion pipe; multiple jet holes are opened on each of the multiple jet pipes; and a one-way valve is provided on each of the multiple jet pipes; a fan is fixedly installed on one side of the shell; a conveying pipe is fixedly installed on the exhaust end of the fan; one end of the conveying pipe is rotatably connected to one end of the diversion pipe; an exhaust pipe is fixedly installed on the top of the shell; a drive mechanism for rotating the diversion pipe is assembled on the shell; and a dust removal mechanism for filtering industrial waste gas is installed on the shell.

[0010] Preferably, the environmentally friendly industrial waste gas desulfurization, denitrification and dust removal integrated device also includes a cleaning mechanism installed on the filter box for cleaning the filter screen.

[0011] Preferably, the cleaning mechanism includes: a high-pressure air pump fixedly installed on one side of the filter box, an air supply pipe fixedly installed on the exhaust end of the high-pressure air pump, one end of the air supply pipe extending into the interior of the filter box; a flexible hose fixedly installed on one end of the air supply pipe, a horizontal pipe fixedly installed on one end of the flexible hose, and multiple air blowing pipes provided on the horizontal pipe; a protective shell fixedly installed on the filter box, an electric telescopic rod fixedly installed on the inner wall of the protective shell, a support block fixedly installed on the output rod of the electric telescopic rod, and the bottom of the support block fixedly connected to the top of the horizontal pipe.

[0015] Compared with related technologies, the environmentally friendly industrial waste gas desulfurization, denitrification and dust removal integrated device provided by this utility model has the following beneficial effects: This utility model provides an environmentally friendly integrated device for desulfurization, denitrification, and dust removal of industrial waste gas. The dust removal mechanism filters the industrial waste gas to be desulfurized and denitrified, effectively intercepting dust and impurities. This prevents large amounts of dust and impurities from entering the treatment solution and contaminating it during subsequent desulfurization and denitrification processes. This reduces the frequency of treatment solution replacement and lowers operating costs over long-term operation. The device exhibits good performance. A fan transports the filtered industrial waste gas to a distribution pipe, from which it is ejected through multiple nozzles on multiple jet pipes. This allows the waste gas to contact the treatment solution within the casing and undergo a chemical reaction, achieving desulfurization and denitrification. A drive mechanism enables the distribution pipe to synchronously rotate multiple stirring rods and jet pipes. This not only evenly distributes the waste gas into the treatment solution but also agitates the solution, preventing sedimentation and stratification, thus ensuring sufficient contact and reaction between the treatment solution and the waste gas, improving desulfurization and denitrification efficiency. An exhaust pipe discharges the treated industrial waste gas outside the device. Attached Figure Description

The terms "first," "second," etc., in the specification or the foregoing drawings are used to distinguish different objects, not to describe a specific order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model provides an environmentally friendly integrated device for desulfurization, denitrification, and dust removal of industrial waste gas, such as... Figure 1-5 As shown, the environmentally friendly industrial waste gas desulfurization, denitrification, and dust removal integrated device includes: a shell 1, which contains a treatment liquid for desulfurizing and denitrifying industrial waste gas; a diversion pipe 2 rotatably mounted on the shell 1; multiple jet pipes 3 and multiple stirring rods fixedly mounted on the diversion pipe 2; multiple jet holes and one-way valves on each of the multiple jet pipes 3; a fan 4 fixedly mounted on one side of the shell 1; a conveying pipe 5 fixedly mounted on the exhaust end of the fan 4; one end of the conveying pipe 5 rotatably connected to one end of the diversion pipe 2; an exhaust pipe 6 fixedly mounted on the top of the shell 1; a drive mechanism mounted on the shell 1 for rotating the diversion pipe 2; and a dust removal mechanism mounted on the shell 1 for filtering industrial waste gas.

[0021] In this embodiment, during operation, the industrial waste gas first enters the dust removal mechanism. In the dust removal mechanism, dust and other impurities in the waste gas are effectively filtered and intercepted. The waste gas after dust removal is drawn by the fan 4 and transported to the diversion pipe 2 through the conveying pipe 5. The waste gas entering the diversion pipe 2 is then evenly discharged into the treatment liquid inside the housing 1 through multiple jet holes on multiple jet pipes 3, so that the waste gas comes into contact with the treatment liquid and undergoes a chemical reaction to achieve desulfurization and denitrification treatment. At this time, the waste gas has been filtered, which can greatly reduce the dust pollution to the treatment liquid. At the same time, the drive mechanism starts and drives the diversion pipe 2 to rotate. When the diversion pipe 2 rotates, it drives multiple stirring rods and multiple jet pipes 3 to rotate synchronously. This not only evenly discharges the industrial waste gas into the treatment liquid, but also stirs the treatment liquid to prevent sedimentation and stratification, thereby ensuring that the treatment liquid and waste gas fully contact and react, improving the desulfurization and denitrification effect. Finally, the waste gas after desulfurization and denitrification treatment will be discharged from the top of the treatment liquid and then discharged from the device through the exhaust pipe 6.

[0022] In a further preferred embodiment of the present invention, the driving mechanism includes: a motor 7 fixedly installed on one side of the housing 1, with a drive gear 8 fixedly sleeved on the output shaft of the motor 7; and a driven gear 9 fixedly sleeved on the diverter pipe 2, the driven gear 9 meshing with the drive gear 8.

[0023] In this embodiment, when the drive mechanism is working, the motor 7 is started, which drives the drive gear 8 to rotate. The drive gear 8 drives the driven gear 9 to rotate synchronously. When the driven gear 9 rotates, it drives the diversion pipe 2, which is fixedly connected to it, to rotate. The rotation of the diversion pipe 2 causes the multiple jet pipes 3 and multiple stirring rods on it to rotate accordingly. When the multiple jet pipes 3 rotate, they can change the discharge position of the exhaust gas in the treatment liquid, so that the exhaust gas contacts the treatment liquid more evenly. The rotation of the multiple stirring rods stirs the treatment liquid in the shell 1, preventing the effective components in the treatment liquid from precipitating and stratifying, ensuring the stability of the performance of the treatment liquid, and improving the desulfurization and denitrification effect on industrial exhaust gas.

[0024] In a further preferred embodiment of this utility model, the dust removal mechanism includes: a base plate 13 fixedly installed at the bottom of the housing 1, a filter box 14 fixedly installed on the top of the base plate 13, a frame 17 fixedly installed on the inner wall of the filter box 14, and a filter screen 18 for filtering industrial waste gas fixedly installed on the inner wall of the frame 17; a connecting pipe 15 fixedly installed on the filter box 14, one end of the connecting pipe 15 being fixedly connected to the air inlet end of the fan 4; and an air inlet pipe 16 fixedly installed on the filter box 14.

[0025] In this embodiment, when the dust removal mechanism is working, the air inlet pipe 16 is connected to the industrial waste gas conveying pipeline. In this way, the industrial waste gas can enter the filter box 14 through the air inlet pipe 16. Inside the filter box 14, the waste gas first comes into contact with the filter screen 18. The filter screen 18 can intercept dust, particulate matter and other impurities in the waste gas. The waste gas filtered by the filter screen 18 enters the fan 4 through the connecting pipe 15. The fan 4 conveys the waste gas from the conveying pipe 5 to the diversion pipe 2, and then evenly discharges it into the treatment liquid in the housing 1 through the multiple jet holes on the multiple jet pipes 3 on the diversion pipe 2, thereby realizing the desulfurization and denitrification treatment of the waste gas. By setting up the dust removal mechanism, impurities in the waste gas can be effectively removed, avoiding impurities from entering the treatment liquid and causing pollution. It can effectively reduce the frequency of treatment liquid replacement and reduce the cost of using the treatment liquid.

[0026] In a further preferred embodiment of the present invention, the environmentally friendly industrial waste gas desulfurization, denitrification and dust removal integrated device also includes a cleaning mechanism installed on the filter box 14 for cleaning the filter screen 18.

[0027] In this embodiment, the cleaning mechanism can be used to clean the dust and impurities attached to the filter screen 18, thereby improving the filtration effect of the filter screen 18 on industrial waste gas.

[0028] In a further preferred embodiment of this utility model, the cleaning mechanism includes: a high-pressure air pump 19 fixedly installed on one side of the filter box 14, an air supply pipe 20 fixedly installed on the exhaust end of the high-pressure air pump 19, one end of the air supply pipe 20 extending into the interior of the filter box 14; a flexible hose 21 fixedly installed on one end of the air supply pipe 20, a horizontal pipe 22 fixedly installed on one end of the flexible hose 21, and multiple air blowing pipes provided on the horizontal pipe 22; a protective shell 23 fixedly installed on the filter box 14, an electric telescopic rod 24 fixedly installed on the inner wall of the protective shell 23, a support block 25 fixedly installed on the output rod of the electric telescopic rod 24, and the bottom of the support block 25 fixedly connected to the top of the horizontal pipe 22.

[0029] In this embodiment, when a large amount of dust and impurities adhere to the filter screen 18 and need to be cleaned, the high-pressure air pump 19 is activated. The high-pressure air pump 19 compresses the outside air and delivers it to the hose 21 through the air supply pipe 20. Then, it enters the horizontal pipe 22 through the hose 21. Finally, a high-speed airflow is blown downward from multiple air blowing pipes on the horizontal pipe 22. At the same time, the electric telescopic rod 24 is activated. The output rod of the electric telescopic rod 24 drives the support block 25 to move horizontally back and forth. The support block 25 drives the horizontal pipe 22 to move, and the horizontal pipe 22 drives multiple air blowing pipes to move. The multiple air blowing pipes move while blowing air downward, so that the dust and impurities attached to the filter screen 18 can be blown off completely, thus cleaning the filter screen 18 and ensuring the filtration effect of the filter screen 18. The blown-off dust and impurities will fall to the bottom of the filter box 14 for easy cleaning.

[0030] In a further preferred embodiment of the present invention, an annular plate 10 is fixedly installed on the inner wall of the exhaust pipe 6, a mesh box 11 is provided on the annular plate 10, activated carbon adsorption particles 12 are provided inside the mesh box 11, and a handle is fixedly installed on the top of the mesh box 11.

[0031] In this embodiment, after the waste gas is treated by the treatment liquid, it passes through the exhaust pipe 6 during the process of being discharged from the device. The waste gas passes through the mesh box 11, where the activated carbon adsorption particles 12 can adsorb the small amount of harmful gases and odor molecules remaining in the waste gas, further purifying the waste gas and improving the quality of waste gas treatment, making the emitted waste gas more environmentally friendly and cleaner. When the activated carbon adsorption particles 12 are saturated and need to be replaced, the mesh box 11 can be removed from the annular plate 10 by the handle, and then a new mesh box 11 containing activated carbon adsorption particles 12 can be replaced. The operation is convenient and quick.

[0032] In a further preferred embodiment of the present invention, the filter box 14 has two inspection ports, and each of the two inspection ports is equipped with a sealing door.

[0033] In this embodiment, the combined use of two inspection ports and a sealed door facilitates personnel to perform maintenance work on the inside of the filter box 14, and also makes it easy to clean dust and impurities inside the filter box 14.

[0034] In a further preferred embodiment of the present invention, an adding pipe is fixedly installed on the top of the housing 1, and a first valve is provided on the adding pipe; a discharging pipe is fixedly installed on one side of the housing 1, and a second valve is provided on the discharging pipe.

[0035] In this embodiment, by opening the first valve, personnel can easily add treatment fluid into the housing 1 through the adding tube, and by opening the second valve, personnel can easily drain the treatment fluid from the housing 1 to replace the treatment fluid.

[0036] In summary, compared with related technologies, this solution, through the use of a dust removal mechanism, can filter the industrial waste gas to be desulfurized and denitrified, effectively intercepting dust and impurities in the waste gas. This effectively prevents large amounts of dust and impurities from entering the treatment liquid and causing pollution during subsequent desulfurization and denitrification processes. Thus, in long-term treatment, it can effectively reduce the frequency of treatment liquid replacement, effectively reducing the cost of treatment liquid use, and achieving better results. Through the use of fan 4, the filtered industrial waste gas can be transported to the diversion pipe 2, and then sprayed out from multiple jet holes on multiple jet pipes 3, so that the industrial waste gas comes into contact with the treatment liquid in the shell 1 and undergoes a chemical reaction to achieve desulfurization and denitrification. Through the use of a drive mechanism, the diversion pipe 2 can drive multiple stirring rods and multiple jet pipes 3 to rotate synchronously, which can not only evenly discharge the industrial waste gas into the treatment liquid, but also stir the treatment liquid to prevent sedimentation and stratification, thereby ensuring that the treatment liquid and waste gas fully contact and react, improving the desulfurization and denitrification effect. Through the use of exhaust pipe 6, the treated industrial waste gas can be discharged outside the device.

[0037] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
