Description

Technical Field

[0001] The utility model relates to the technical field of denitration equipment, in particular to a soot blowing device for denitration equipment. Background Art

[0002] In the denitrification chamber of traditional denitrification equipment, the denitrification catalyst layer assembled therein is generally composed of several catalysts arranged side by side in a matrix, and denitrification holes are arranged on the denitrification catalyst block. The exhaust gas passes through the denitrification holes on the denitrification agent block for denitrification and then passes through the bag dust collector before being discharged. Since the exhaust gas contains a lot of dust and particles, and the aperture of the denitrification holes is small, the denitrification holes are prone to blockage during the denitrification work, affecting the denitrification effect of the exhaust gas. Therefore, the denitrification chamber of the denitrification equipment generally needs to be equipped with a soot blowing device to blow soot through the denitrification holes of the denitrification agent block.

[0003] In the prior art, for example, a utility model patent with authorization announcement number CN212576013U discloses a soot blowing device for a denitration device. By setting a vertical blowing mechanism in conjunction with a reciprocating drive mechanism, high-pressure air is blown back and forth on the through holes on the denitration catalyst layer to ensure that the dust attached to the through holes falls off, thereby ensuring the denitration effect.

[0004] However, the above-mentioned device still has the following problems in actual use: the main air supply duct and the diversion duct are fixed vertically, which makes the horizontal length of the device longer and the width of the hole required for entering and exiting the desoldering chamber larger. This leads to high requirements for the use conditions of the desoldering equipment for the soot blowing device, insufficient adaptability, and difficulty in meeting diverse usage needs. Utility Model Content

[0005] The purpose of the utility model is to provide a soot blowing device for denitration equipment to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a soot blowing device for denitrification equipment, comprising:

[0007] A main air supply duct, wherein a connecting hose is provided on the side wall of the main air supply duct, and a driving ring is movably connected to the outer wall of the main air supply duct and can move axially along the main air supply duct;

[0008] An air supply branch pipe, one end of which is connected to the main air supply pipe via a connecting hose, a first hinged member being connected between the air supply branch pipe and the main air supply pipe, and a transmission connecting rod being movably connected between the side wall of the air supply branch pipe and the side wall of the drive ring;

[0009] The translation drive mechanism is arranged on the main air supply pipe and is used to drive the drive ring to move back and forth along the axial direction of the main air supply pipe.

[0010] Preferably, a plurality of jet nozzles are fixedly arranged on the outer wall of the air supply branch pipe. The plurality of jet nozzles communicate with the inner cavity of the air supply branch pipe, and the plurality of jet nozzles are arranged at parallel intervals.

[0011] Preferably, second hinge members are hinged to both ends of the transmission link. The second hinge members located at both ends of the transmission link are respectively fixedly connected to the driving ring and the side wall of the air supply branch pipe.

[0012] Preferably, a linear channel recessed inward is provided on the outer wall of the main air supply pipe, and the translation driving mechanism is arranged inside the linear channel.

[0013] Preferably, the translation driving mechanism includes a one-way screw. The one-way screw is rotatably arranged inside the linear channel. A small servo motor is fixedly installed inside the linear channel. The small servo motor is used to drive the one-way screw to rotate. A nut seat is threadedly connected to the outer wall of the one-way screw, and the nut seat is fixedly arranged with the driving ring.

[0014] Preferably, a guide block is fixedly connected to the inner side of the driving ring. The outer wall of the guide block is movably inserted into the inner side of the linear channel, and the nut seat is fixedly connected to the middle of the guide block.

[0015] The technical effects and advantages of the present utility model:

[0016] By assembling the first hinge member between the main air supply pipe and the air supply branch pipe, the air supply branch pipe can rotate at the side position of the main air supply pipe. Then, in cooperation with the driving ring movably connected to the outer wall of the main air supply pipe and controlled by the translation driving mechanism, and the transmission link hinged between the driving ring and the air supply branch pipe, the air supply branch pipe can be rotated and unfolded or folded, so that the size requirement of the soot blowing device for the inlet and outlet ports of the denitration chamber is relatively low, and the adaptability in use is high, thus better meeting the use requirements.

Detailed implementation manners

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides a soot blowing device for a denitration device as shown in Figures 1-3 Figure 8, which includes a main air supply pipe 100, an air supply branch pipe 200 and a translation drive mechanism. A plurality of jet nozzles 201 are fixedly arranged on the outer wall of the air supply branch pipe 200. The plurality of jet nozzles 201 are communicated with the inner cavity of the air supply branch pipe 200, and the plurality of jet nozzles 201 are arranged at parallel intervals. The assembly of the plurality of jet nozzles 201 can match the number of soot blowing through holes in the denitration block. Therefore, when the air supply branch pipe 200 translates, soot blowing through hole operations in a plurality of denitration holes can be synchronously realized. A connecting hose 110 is provided on the side wall of the main air supply pipe 100. A drive ring 103 that can move axially along the main air supply pipe 100 is movably connected to the outer wall of the main air supply pipe 100. One end of the air supply branch pipe 200 is communicated with the main air supply pipe 100 through the connecting hose 110. The connection of the air supply branch pipe 200 to the main air supply pipe 100 through the connecting hose 110 not only satisfies the transportation of gas, but also enables the air supply branch pipe 200 to rotate and fold smoothly. A first hinge 101 is connected between the air supply branch pipe 200 and the main air supply pipe 100. The first hinge 101 is used to realize the rotational connection between the air supply branch pipe 200 and the main air supply pipe 100. In this way, the air supply branch pipe 200 can be rotated and unfolded or folded on the side of the main air supply pipe 100. A transmission connecting rod 104 is movably connected between the side wall of the air supply branch pipe 200 and the side wall of the drive ring 103. The translation drive mechanism is arranged on the main air supply pipe 100. The translation drive mechanism is used to drive the drive ring 103 to reciprocate axially along the main air supply pipe 100. Through the connection of the transmission connecting rod 104, when the translation drive mechanism drives the drive ring 103 to move axially along the main air supply pipe 100, it can drive the air supply branch pipe 200 to rotate around the first hinge 101, so as to control the air supply branch pipe 200 to be in an unfolded position perpendicular to the main air supply pipe 100 or a storage position close to horizontal with the main air supply pipe 100, which is convenient for the main air supply pipe 100 to enter and exit at the port position of the denitration chamber.

[0023] It should be noted that there is no "Figure 8" in the original text you provided. I assume it according to the context. If there is an error, please correct it according to the actual situation.It should be noted that second hinge members 105 are hinged to both ends of the transmission connecting rod 104. The second hinge members 105 located at both ends of the transmission connecting rod 104 are fixedly connected to the driving ring 103 and the side wall of the air supply branch pipe 200 respectively. With the arrangement of the second hinge members 105, rotational connections can be achieved at both ends of the transmission connecting rod 104. Both the first hinge member 101 and the second hinge member 105 can adopt hinge members in the prior art, such as hinge members composed of a U-shaped seat and a pin. Therefore, no further description will be given here.

[0024] Furthermore, a linear channel 102 recessed inward is provided on the outer wall of the main air supply pipe 100, and the translation driving mechanism is arranged inside the linear channel 102. The arrangement of the linear channel 102 can play a role in receiving and guiding, which is not only convenient for the installation of the translation driving mechanism, but also can keep the driving ring 103 stable during the movement process without deflection; in a preferred embodiment, the translation driving mechanism includes a unidirectional screw 106, the unidirectional screw 106 is rotatably arranged inside the linear channel 102, a small servo motor 109 is fixedly installed inside the linear channel 102, the small servo motor 109 is used to drive the unidirectional screw 106 to rotate, a nut seat 108 is threadedly connected to the outer wall of the unidirectional screw 106, the nut seat 108 is fixedly arranged with the driving ring 103, a guiding block 107 is fixedly connected to the inside of the driving ring 103, the outer wall of the guiding block 107 is movably inserted into the inside of the linear channel 102 of the main air supply pipe 100, the nut seat 108 is fixedly connected to the middle of the guiding block 107. By matching the guiding block 107 arranged inside the driving ring 103 with the linear channel 102 on the outer wall of the main air supply pipe 100, when the driving ring 103 moves along the axial direction of the main air supply pipe 100, due to the limiting and guiding effect of the linear channel 102 on the guiding block 107, the driving ring 103 will not deflect during the transverse movement and maintain the stability of the movement. In this way, the situation that the nut seat 108 rotates along with the rotation of the unidirectional screw 106 can be avoided. The small servo motor 109 can be electrically connected to an external power supply through an external switch or a control box. By controlling the clockwise or counterclockwise rotation of the small servo motor 109, the unidirectional screw 106 can be rotated while driving the nut seat 108 to move, thereby providing a driving force for the movement of the driving ring 103 to facilitate controlling the deployment state of the air supply branch pipe 200.

[0025] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
