Description

Technical Field

[0001] The present application relates to the technical field of flue gas purification and treatment equipment, and more specifically, to a kiln flue gas filtering device. Background Art

[0002] In the production process of electronic glass, the kiln flue gas needs to be purified before it can be discharged into the atmosphere. In the prior art, the ash hopper installed at the bottom of the ceramic filter tube for the kiln flue gas purification system has some defects: only one ash hopper is designed, and the angle between the inner side of the ash hopper and the horizontal plane is small, so that the dust after filtration is easy to accumulate on the inner side of the ash hopper and become hardened. The dust accumulation is serious and requires frequent cleaning. Cleaning is difficult, time-consuming and labor-intensive, resulting in high energy consumption for dust discharge and high production costs. At the same time, due to the need to increase the frequency of ash discharge, it will also have a negative impact on the stability of the kiln pressure of the kiln, seriously affecting the stability of production quality. Utility Model Content

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a kiln smoke filtering device, which includes:

[0005] A kiln fume filter chamber, wherein the kiln fume filter chamber has a fume inlet and a fume outlet;

[0006] At least two ash hoppers are arranged in sequence along the horizontal direction at the bottom of the kiln smoke filter bin, the upper port of the ash hopper is connected to the kiln smoke filter bin, the ash hopper gradually narrows downward along the vertical direction, and the angle between the inner side surface of the side wall of the ash hopper and the horizontal plane is in the range of 60° to 80°.

[0007] Furthermore, the angle between the inner side surface of the side wall of the ash hopper and the horizontal plane ranges from 70° to 75°.

[0008] Furthermore, there are two ash hoppers arranged at the bottom of the kiln smoke filter bin.

[0009] Furthermore, the kiln fume filtering device comprises a ceramic layer arranged on the inner side of the side wall of the ash hopper.

[0010] Furthermore, the kiln fume filtering device includes a vibration device arranged on the outer side of the side wall of the ash hopper.

[0011] Furthermore, a plurality of the vibration devices are arranged at intervals on the side wall of the ash hopper.

[0012] Further, a plurality of the vibration devices are arranged around the vertical axis of the ash hopper at equal angles.

[0013] Furthermore, the ash hopper is a conical structure.

[0014] Furthermore, the side wall of the ash hopper is provided with an inspection port connecting the inside and outside of the ash hopper, the inspection port is provided with an openable and closable inspection door, the inspection door is provided with a manual cleaning hole, and the manual cleaning hole is provided with an openable and closable hole cover.

[0015] Furthermore, the kiln fume filtration device comprises a purge air supply pipeline extending into the kiln fume filtration chamber, and the purge air supply pipeline is matched with an electric control switch to control the on-off of the purge air supply pipeline.

[0016] The beneficial effects of the kiln fume filtration equipment provided by this application are:

[0017] In the kiln flue gas filtration equipment provided by the embodiment of the utility model, since at least two ash hoppers are arranged at the bottom of the kiln flue gas filtration bin, compared with the traditional situation of only one ash hopper, when the ash hopper design height is inconvenient, the angle between the inner side surface of the side wall of the ash hopper and the horizontal plane can be increased, and the angle between the inner side surface of the side wall of the ash hopper and the horizontal plane can be designed to be in the range of 60° to 80°, while the angle between the inner side surface of the side wall of a traditional ash hopper and the horizontal plane is usually 45° to 50°. Therefore, the kiln flue gas filtration equipment of the present invention significantly increases the angle between the inner side surface of the side wall of the ash hopper and the horizontal plane, thereby reducing the surface pressure between dust and the inner surface, reducing dust accumulation and compaction, thereby improving the cleaning efficiency and reducing the cleaning frequency.

[0018] In a further solution, the kiln flue gas filtration equipment includes a ceramic layer arranged on the inner side of the side wall of the ash hopper. The ceramic layer can increase the smoothness of the inner side of the side wall of the ash hopper, reduce the friction coefficient between the dust and the inner side of the side wall of the ash hopper, reduce the friction force, and reduce the adhesion between the dust and the inner side, which can also reduce the accumulation of dust.

[0019] In a further solution, the kiln flue gas filtering device includes a vibration device arranged on the outer side of the side wall of the ash hopper.

[0041] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0042] See also Figure 1 and Figure 2 The embodiment of the utility model provides a kiln smoke filtering device, which includes: a kiln smoke filtering chamber 100 and at least two ash hoppers 200.

[0043] The kiln fume filter chamber 100 may be provided with components such as ceramic filter tubes, and the kiln fume filter chamber 100 is provided with a fume inlet 101 and a fume outlet 102 .

[0044] In specific operation, the fume to be purified (e.g., the fume from the kiln in the production process of electronic glass) can enter the interior of the kiln fume filter chamber 100 through the fume inlet 101, and after being purified (e.g., filtered by a ceramic filter tube), it flows out of the kiln fume filter chamber 100 through the fume outlet 102;

[0045] In addition, at least two ash hoppers 200 are arranged in sequence along the horizontal direction at the bottom of the kiln flue gas filter chamber 100, the upper port of the ash hopper 200 is connected to the kiln flue gas filter chamber 100, the ash hopper 200 gradually narrows downward along the vertical direction, and the angle between the inner side surface of the side wall 201 of the ash hopper 200 and the horizontal plane ranges from 60° to 80°.

[0046] In the kiln flue gas filtration equipment provided by the embodiment of the utility model, since at least two ash hoppers 200 are arranged at the bottom of the kiln flue gas filtration chamber 100, compared with the conventional situation where there is only one ash hopper 200, when the design height of the ash hopper 200 is inconvenient, the angle between the inner side surface of the side wall 201 of the ash hopper 200 and the horizontal plane can be increased, and the angle between the inner side surface of the side wall 201 of the ash hopper 200 and the horizontal plane can be designed to be in the range of 60° to 80°, while the angle between the inner side surface of the side wall 201 of a conventional ash hopper 200 and the horizontal plane is usually 45° to 50°.

[0047] It can be seen that the kiln flue gas filtration equipment significantly increases the angle between the inner surface of the side wall 201 of the ash hopper 200 and the horizontal plane, thereby reducing the surface pressure between the dust and the inner surface, reducing dust accumulation and compaction, thereby improving the cleaning efficiency and reducing the cleaning frequency.

[0048] It can be understood that the angle between the inner surface of the side wall 201 of the ash hopper 200 and the horizontal plane referred to in the present invention is in the range of 60° to 80°, which means that when observing the ash hopper 200 from any direction, the angle between the inner surface of the side wall 201 of the ash hopper 200 and the horizontal plane is in the range of 60° to 80°.

[0049] Specifically, when observing the ash hopper 200 from any direction, that is, whether observing (measuring) from the front, back, side or other directions of the kiln flue gas filtration equipment, the angle between the inner side surface of the side wall 201 of the ash hopper 200 and the horizontal plane is in the range of 60° to 80°.

[0050] Combination Figure 1 and Figure 2 It is understood that the angle between the inner side surface of the side wall 201 of the ash hopper 200 and the horizontal plane when observed (measured) from the front of the kiln flue gas filtration equipment is β, 60°≤β≤80°, and the angle between the inner side surface of the side wall 201 of the ash hopper 200 and the horizontal plane when observed (measured) from the side of the kiln flue gas filtration equipment is α, 60°≤α≤80°.

[0051] According to a preferred embodiment of the kiln fume filtration device of the present invention, the ash hopper 200 is a conical structure, so that when the ash hopper 200 is observed from any direction, the angle between the inner side surface of the side wall 201 of the ash hopper 200 and the horizontal plane is consistent.

[0052] Of course, as other embodiments of the kiln flue gas filtration device of the utility model, if the ash hopper 200 is not a conical structure, when observing the ash hopper 200 from any direction, there may be inconsistencies in the angles between the inner side surfaces of the side walls 201 of the ash hopper 200 and the horizontal plane, but these inconsistent angles must still be within the range of 60° to 80°.

[0053] According to an embodiment of the kiln smoke filtration device of the utility model, the smoke inlet 101 is arranged at the lower part of the warehouse wall of the kiln smoke filtration chamber 100, and the smoke outlet 102 is arranged at the upper part of the warehouse wall of the kiln smoke filtration chamber 100, which is more suitable for the flow path of the smoke. Of course, it is not limited to such a specific arrangement scheme. It can be understood that the arrangement points of the smoke inlet 101 and the smoke outlet 102 on the warehouse wall of the kiln smoke filtration chamber 100 are flexible and variable.

[0054] It can be understood that in order to strike a balance between cost and the effect of reducing ash accumulation and compaction, according to the preferred embodiment of the kiln flue gas filtration equipment of the utility model, two ash hoppers 200 are arranged at the bottom of the kiln flue gas filtration bin 100. The structural shape and size of the two ash hoppers 200 may be consistent or inconsistent, but it is preferred that the structural shape and size of the two ash hoppers 200 are consistent, which is also convenient for mass production, installation and replacement of the ash hoppers 200.

[0055] Of course, as other embodiments, the number of the ash hoppers 200 may be 3, 4, 5 or more.

[0056] Furthermore, the angle between the inner side surface of the side wall 201 of the ash hopper 200 and the horizontal plane is preferably in the range of 70° to 75°, and specifically 70° and 75° are preferred, and 71°, 72°, 73°, 74° and the like may also be selected.

[0057] According to one embodiment of the utility model, the kiln smoke filtering device includes a ceramic layer 1 arranged on the inner side of the side wall 201 of the ash hopper 200. The benefits of setting the ceramic layer 1 will be described below, and the ceramic layer 1 can also be replaced by a material layer of similar properties.

[0058] In this embodiment, specifically, the ceramic layer 1 can be set on the inner surface of the side wall 201 of the ash hopper 200 by spraying. The ceramic layer 1 can increase the smoothness of the inner surface of the side wall 201 of the ash hopper 200, reduce the friction coefficient between the dust and the inner surface of the side wall 201 of the ash hopper 200, reduce the friction force, and reduce the adhesion between the dust and the inner surface, which can also play an effect of reducing dust accumulation and compaction.

[0059] As another embodiment, the ceramic layer 1 may also be directly bonded to the inner side surface of the side wall 201 of the ash hopper 200 .

[0060] According to an embodiment of the present invention, the ash hopper 200 may be made of steel or other suitable metal materials.

[0061] According to an embodiment of the utility model, the kiln smoke filtering device includes a vibration device 2 arranged on the outer side of the side wall 201 of the ash hopper 200. When cleaning is required, the vibration device 2 is started to make the ash hopper 200 vibrate at the same frequency as a whole, further improving the cleaning effect.

[0062] In this embodiment, although a vibration device 2 is installed on the outer surface of the side wall 201 of the ash hopper 200 to achieve the vibration cleaning effect, according to a preferred embodiment of the utility model, a plurality of vibration devices 2 are arranged at intervals on the side wall 201 of the ash hopper 200 to increase the vibration points to further improve the cleaning effect.

[0063] In this embodiment, a plurality of vibration devices 2 may be arranged around the vertical axis of the ash hopper 200 at equal angles, but the arrangement is certainly not limited to this specific arrangement.

[0064] In this embodiment, the vibration device 2 may be a vibration motor or the like which is replaceable.

[0065] According to one embodiment of the utility model, a maintenance port connecting the inside and outside of the ash hopper 200 is provided on the side wall 201 of the ash hopper 200, and an openable and closable maintenance door 3 is installed at the maintenance port. The maintenance door 3 has a manual cleaning through hole, and an openable and closable hole cover 5 is installed at the manual cleaning through hole. The side wall 201 of the ash hopper 200 can horizontally extend a cleaning pipe 4 outward, and the maintenance door 3 can be installed at the outer pipe mouth of the cleaning pipe 4 in an openable and closable manner. The maintenance door 3 can be specifically installed at the outer pipe mouth of the cleaning pipe 4 by fasteners such as bolts and nuts, and the hole cover 5 can also be installed at the manual cleaning through hole of the maintenance door 3 by fasteners such as bolts and nuts. After removing (or opening) the maintenance door 3, it is convenient for maintenance personnel to enter the cleaning pipe 4 for operation. When the maintenance door 3 is not removed (or opened), the hole cover 5 can be removed (or opened), and a cleaning rod can be extended inward to hit the inner side of the ash hopper 200 for cleaning. The size of the manual ash cleaning through hole is much smaller than that of the inspection port. The manual ash cleaning through hole is provided to facilitate manual ash cleaning and also to avoid fully opening the inspection door 3 of the equipment to affect the kiln pressure.

[0066] As other embodiments, the manual cleaning through hole is not limited to being an entry hole for manual cleaning, and automated equipment may also be used to control a cleaning rod or the like to hit the inner side of the ash hopper 200 for cleaning.

[0067] According to a specific embodiment of the present invention, the cleaning rod can be made of metal material, such as a steel rod.

[0068] According to one embodiment of the utility model, the kiln smoke filtering device includes a purge air supply duct 6 extending into the kiln smoke filtering chamber 100, and the purge air supply duct 6 is matched with an electric control switch 7 to control the on and off of the purge air supply duct 6. The electric control switch 7 can adopt a pulse switch, etc. After the electric control switch 7 controls the purge air supply duct 6 to be turned on, air can be blown into the purge air supply duct 6 to flush the dust adsorbed by the ceramic filter tube into the ash hopper 200.
