Description

Technical Field

[0001] This application relates to the technical field of waste gas treatment, and particularly to a soot blowing device, a denitration device and a waste gas treatment system. Background Art

[0002] During the glass production process, a large amount of soot is generated, and the soot needs to enter the denitration tower for denitration treatment. After working for a long time, a large amount of soot will be deposited on the surface of the catalyst in the denitration tower, blocking the pores of the catalyst and affecting the operation of the catalyst. Therefore, it is necessary to regularly use a rake-type soot blower to clean the inside of the denitration tower to ensure the normal operation of the denitration tower.

[0003] The rake-type soot blower generally consists of a propulsion device, a main soot blowing pipe and rake pipes. The propulsion device is arranged outside the furnace, and several rake pipes are connected to the main soot blowing pipe and arranged in the furnace. The other end of the main soot blowing pipe is connected to the propulsion device outside the furnace. The propulsion device pushes the rake pipes to move back and forth in the furnace. While moving, high-pressure air is ejected from the rake pipes to blow the inside of the furnace. However, the main soot blowing pipe is generally arranged on the support track, and both the support track and the main soot blowing pipe are extremely prone to accumulating soot. These soot can easily cause jamming during the reciprocating movement of the rake-type soot blower, affecting the soot cleaning. Summary of the Utility Model

[0025] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0026] For ease of description, spatial relative relationship terms may be used in the text to describe the relative position relationship or movement of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms are, for example, "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", "front", "rear", etc. Such spatial relative relationship terms are intended to include different orientations of the device during use or operation other than the orientations depicted in the figure. For example, if the device in the figure undergoes a position flip, attitude change, or motion state change, then these directional indications will change accordingly. For example, an element described as "below" or "beneath" other elements or features will then be oriented as "above" or "over" other elements or features. Therefore, the exemplary term "below" can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0027] Referring to Figure 1 and Figure 2 as shown, the present utility model provides a soot blowing device, which includes: a driving component 1, a rake-type soot blower 2, a support rail 3, and a dust-proof cover 4; the rake-type soot blower 2 is slidably arranged on the support rail 3. The structure of the rake-type soot blower 2 is prior art and will not be described in detail here. A part of the rake-type soot blower 2 is located inside the denitration tower, and a part is located outside the denitration tower. A part of the support rail 3 is located inside the denitration tower, and a part is located outside the denitration tower; the driving component 1 is connected to one end of the rake-type soot blower 2 and drives the rake-type soot blower 2 to move along the length direction of the support rail 3. Specifically, the driving component 1 includes a motor 11, a first slider 13, and a frame 12. The first slider 13 is respectively connected to the motor 11 and one end of the rake-type soot blower 2. The motor 11 is slidably arranged on the frame 12 and can reciprocate along the length direction of the frame 12. When soot blowing is performed, the motor 11 will reciprocate along the length direction of the frame 12 on the frame 12, and at the same time drive the rake-type soot blower 2 to reciprocate along the length direction of the support rail 3, and blow the dust deposited on the surface of the catalyst and in the catalyst pores inside the denitration tower down during the reciprocating movement. The part of the support rail 3 located inside the denitration tower is accommodated in the dust-proof cover 4; openings 41 are provided at both ends of the dust-proof cover 4, and a dust-blocking member 42 is provided on the circumference of the opening 41 at the end far from the driving component 1. Among them, the dust-blocking member 42 can be a scraper or a brush. The support rail 3 extends into the dust-proof cover 4 from the opening 41 close to the driving component 1, and the rake-type soot blower 2 penetrates through the two openings 41 of the dust-proof cover 4 and extends above the catalyst inside the denitration tower.

[0028] When soot blowing work is carried out, part of the raised dust will directly fall on the dust-proof cover 4 and will not fall on the support rail 3. Part of the dust will fall on the rake soot blower 2 extending outside the dust-proof cover 4. When the rake soot blower 2 moves towards the driving component 1, the dust on the rake soot blower 2 extending outside the dust-proof cover 4 will be blocked outside the dust-proof cover 4 by the dust-blocking member 42 on the dust-proof cover 4 and will not be brought onto the support rail 3 either. Therefore, the deposition of soot on the support rail 3 can be avoided during the soot blowing process.

[0029] Further, a plurality of second sliders 5 are arranged on one side of the rake soot blower 2 facing the support rail 3. By means of the second sliders 5, the friction between the rake soot blower 2 and the support rail 3 can be reduced, and the reciprocating movement of the rake soot blower 2 on the support rail 3 is smoother.

[0030] Further, referring to Figure 1 and Figure 3 As shown, a plurality of spaced ash discharge holes 31 are formed in the part of the support rail 3 located inside the dust-proof cover 4. If a small amount of soot enters the support rail 3, when the rake soot blower 2 reciprocates, the second slider 5 will push the small amount of soot deposited on the support rail 3 to the ash discharge holes 31 on the support rail 3 for discharge. Through the ash discharge holes 31, the deposition of soot on the support rail 3 can be further reduced.

[0031] In one embodiment, referring to Figure 1 and Figure 3 As shown, at least one cleaning roller 6 is installed on each side of the support rail 3 and is arranged opposite to each other. The cleaning roller 6 is located inside the dust-proof cover 4, and the rake soot blower 2 is clamped between the two cleaning rollers 6. When the rake soot blower 2 reciprocates and passes between the cleaning rollers 6, the cleaning rollers 6 will clean the dust on the rake soot blower 2 to avoid excessive deposition on the support rail 3.

[0032] In another embodiment, the soot blowing device further includes an ultrasonic vibration member 7. The ultrasonic vibration member 7 is installed on the side of the rake soot blower 2 close to the driving component 1. Before the rake soot blower 2 needs to move towards the driving component 1, the ultrasonic vibration member 7 can be turned on, and the soot falling on the rake soot blower 2 is vibrated off through ultrasonic vibration to avoid excessive deposition on the rake soot blower 2, and the soot brought into the dust-proof cover 4 subsequently can be minimized as much as possible.

[0033] This application also proposes a denitration device, and the denitration device includes the soot blowing device in the above-mentioned embodiment.

[0034] This application also proposes an exhaust gas treatment system, and the exhaust gas treatment system includes the soot blowing device in the above-mentioned embodiment or the denitration device in the above-mentioned embodiment.
