[0002] Selective catalytic reduction refers to the use of a reducing agent to selectively react with NOx in flue gas under the action of a catalyst to generate non-toxic and non-polluting N2 and H2O. However, during the long-term catalytic denitrification process, dust particles in the flue gas are prone to block the catalytic holes.

[0003] At present, in the previous cleaning devices, a driving device is usually arranged outside the reactor, which extends into the reactor through a transmission rod. There are multiple cleaning brush heads above the catalyst inside the reactor. The transmission rod drives the multiple cleaning brush heads located inside the reactor to move back and forth to clean the dust on the surface of the catalyst. However, during the cleaning process of this cleaning device, since the multiple brush heads are only connected to one transmission rod, there will be shaking during the reciprocating movement, resulting in incomplete cleaning of the brush heads.

[0046] Example 1

[0047] like Figure 1-6 As shown, the utility model provides a mobile cleaning device, which includes: a main pipe, three soot blowing pipes, a main hanger assembly and a sub-hanger assembly.

[0048] The three soot blowing pipes are arranged at intervals along the length direction of the main pipe, and the soot blowing pipes are arranged at a certain angle to the main pipe. Specifically, the soot blowing pipes are arranged at a vertical angle to the main pipe. The soot blowing pipes are connected to the main pipe, and a plurality of air outlets are opened at the bottom of the soot blowing pipes.

[0049] The main hanger assembly includes a main track and two main hangers. The main track is arranged parallel to and above the main pipe, and the main track is fixedly arranged. The main hanger is slidably connected to the main track. The bottom of the main hanger is connected to the main pipe, so that the main pipe is slidably connected to the main track through the main hanger.

[0050] The auxiliary hanger assembly includes an auxiliary track and an auxiliary hanger. The auxiliary track located above the sootblowing pipe is arranged parallel to the main track, and both are fixed above the main pipe and the sootblowing pipe. The auxiliary hanger is slidably connected to the auxiliary track, and the bottom of the auxiliary hanger is connected to at least one of the sootblowing pipes.

[0051] The sootblowing pipes are connected at intervals at the bottom of the main pipe, and are hoisted and connected above the main pipe by the main hanger assembly. The main pipe can reciprocate along the main track. The sootblowing pipes are hoisted and connected above the auxiliary hanger assembly, and the auxiliary hanger assembly is parallel to the main hanger assembly. The main pipe and the sootblowing pipes are supported by the two hanger assemblies to ensure that the sootblowing pipes reduce or even avoid shaking and overturning during the reciprocating motion.

[0052] To ensure the stability of the connection between the auxiliary hanger assembly and the sootblowing pipe, two auxiliary hanger assemblies are symmetrically arranged along the length direction of the main hanger assembly. The auxiliary hangers in the two auxiliary hanger assemblies are fixedly connected to both ends of the sootblowing pipe. Since the main pipe is connected to the middle part of the sootblowing pipe, the main pipe is suspended by the main hanger assembly, and both ends of the sootblowing pipe are suspended by two auxiliary hanger assemblies, so that the main pipe and the sootblowing pipe are suspended by the hanger assembly with guiding and supporting functions, so that the main pipe and multiple sootblowing pipes can maintain a good stability effect during the reciprocating movement.

[0053] In this embodiment, the auxiliary hanger has the same structure as the main hanger.

[0054] Wherein, the main hanger includes: a hanger frame, a hanger rod and a connecting seat.

[0055] The hanging frame is slidably sleeved on the main track, and a pulley is rotatably connected to the top of the hanging frame, which is slidably connected to the main track through the pulley, so that the hanging frame can slide back and forth on the main track, and a waist-shaped hole is vertically opened on the side of the bottom of the hanging frame, and a cross bar is fixed to the hanging frame; the top of the hanging rod passes through the cross bar and is fastened, and the bottom of the hanging rod is fixedly connected to the main pipe. The hanging rod can adopt a screw rod, and its top can be locked and connected to the cross bar through nuts and other fasteners. The hanging rod can move up and down, and then the nut is tightened to facilitate the height adjustment of the main pipe below, thereby adjusting the gap between the sootblowing pipe below and the catalyst, and the gap is controlled within 30-40mm; the connecting seat is fixed on the main pipe, and the connecting seat is fastened to the waist-shaped hole through fasteners. Bolts and other fasteners are passed through the connecting seat, and the fasteners inserted into the waist-shaped hole are tightened by nuts, so that during the up and down movement of the hanging rod, the fasteners move up and down in the waist-shaped hole, and are tightened and fixed after being adjusted into place.

[0056] Wherein, the sootblowing tube comprises: a tube body and an air inlet flange.

[0057] At least one exhaust hole is provided at the bottom of the tube body along its length direction, and at least one slag cleaning port is provided on the tube body. The slag cleaning port can be located at the top, side and end of the tube body which are different from the bottom. A screw cover is fastened on the slag cleaning port. When the soot blowing pipe is used for cleaning, the screw cover is sealed and fastened on the slag cleaning port. When the inside of the soot blowing pipe needs to be cleaned, the screw cover can be opened; the air inlet flange is connected to the top of the tube body, and the soot blowing pipe is connected to the external pipeline through the air inlet flange. The detachable connection is realized through the air inlet flange, which is convenient for disassembly and assembly.

[0058] When dust accumulates inside the pipe body and blocks the air outlet, you can disassemble it from the air inlet flange, then unscrew the screw cover on the slag cleaning port, clean the dust accumulated in the pipe body, and then pour it out through the slag cleaning port. This can prevent dust from accumulating in the air outlet from the inside. After cleaning, tighten the screw cover on the slag cleaning port.

[0059] Specifically, the tube body includes: a square box body and a herringbone box top closed on the top of the square box body, which can not only increase the internal space of the tube body so that the internal air pressure can be balanced as much as possible, but also fully enhance the rigidity of the tube body.

[0060] In order to improve the structural strength of the entire tube body and prevent the tank body from bursting due to over-pressure gas, the present embodiment also includes a plurality of pins, which are arranged at intervals along the length direction of the tube body. Both ends of the pins are connected and fixed to the side walls of the tube body to reinforce the tube body. Specifically, both ends of the pins are fixedly connected to the two side walls of the square box body.

[0061] It also includes an inflation pipe, which is connected between the air inlet flange and the tube body. The top of the inflation pipe is connected to the air inlet flange, and the bottom of the inflation pipe extends obliquely to both ends along the length direction of the tube body and is connected to the center of the top of the tube body. The bottom of the inflation pipe extends in the length direction of the tube body, so that the inflation pipe forms an eight-shaped shape as a whole. In this way, compressed air can fully and evenly enter the tube body below, while at the same time increasing the structural strength between the inflation pipe and the tube body.

[0062] In this embodiment, the slag cleaning port is opened at the top near the end of the tube body;

[0063] Specifically, the inner diameter of the slag cleaning port is arranged tangent to the inner wall of the tube body, so that the dust inside the tube body can be poured out from the slag cleaning port more conveniently, and there is as little dead angle as possible when pouring out.

[0064] In order to facilitate the cleaning of dust inside the tube body, two slag cleaning ports are provided, and the two slag cleaning ports are symmetrically arranged on the tube body with the center of the tube body. In this way, the internal dust can be discharged from the other slag cleaning port by ventilating one of the slag cleaning ports.

[0065] The air outlet holes at the bottom of the tube body are evenly spaced; specifically, to ensure that the blowing force of the air outlet holes is balanced, the aperture of the air outlet holes at the bottom is different according to the pressure. The air outlet holes are specifically set to gradually increase in diameter from the middle to both ends. In this embodiment, the aperture in the middle can be 1.8 mm, and the aperture at both ends is 2.0 mm.

[0066] like Figure 6 As shown, in order to facilitate cleaning, the bottom of the inflation pipe at both ends of the main pipe is tilted outward, and the bottom of the cleaning pipe is extended outward so that the cleaning pipe can be as close to the inner wall of the reactor as possible to reduce cleaning dead angles.

[0067] Similarly, in order to reduce the cleaning dead angle, the air outlet holes at the bottom of the soot blowing pipes on the outermost sides are set to be located closer to the bottom and the outside, so as to expand the blowing range and reduce the cleaning dead angle.

[0068] Example 2

[0069] like Figure 7 As shown, this embodiment also discloses a cleaning assembly, which includes four cleaning devices in the above-mentioned embodiment 1, and the four cleaning devices are arranged in sequence along a direction perpendicular to the main pipe. The main pipes in the four cleaning devices are arranged in parallel, and the dust cleaning pipes at the bottom are arranged one by one on the same cleaning line.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
