Description

Technical Field

[0001] This utility model relates to the field of compressed air supply technology, specifically to an energy-saving and carbon-reducing SCR denitrification compressed air device. Background Technology

[0002] Currently, in SCR denitrification equipment, compressed air is used to supply air to rake sootblowers for catalyst cleaning. To ensure sufficient air supply to the rake sootblowers and to ensure that cleaning is not affected during maintenance of compressed air equipment (air compressors) under different operating conditions, multiple air compressors are often used, with backup air compressors provided. Generally, there are two configuration methods. When multiple production lines are equipped with denitrification SCR systems simultaneously, and an air compressor station cannot be established, the redundancy of multiple backup air compressors in each compressed air system leads to energy waste and equipment wear.

[0003] Chinese patent application number 202323313516.5 discloses an energy-saving and carbon-reducing SCR denitrification compressed air device, including a first compressed air supply mechanism, a second compressed air supply mechanism, a first standby compressed air supply mechanism, a second standby compressed air supply mechanism, a first air storage mechanism, and a second air storage mechanism. This SCR denitrification compressed air device provides an energy-saving and carbon-reducing compressed air system. Compressed air can be supplied by activating one or more standby air compressors according to the needs of multiple production lines and actual operating conditions. This ensures a sufficient supply of compressed air under abnormal operating conditions while reducing energy loss and equipment wear from frequent standby and loading of standby air compressors under normal operating conditions, thereby achieving energy saving, carbon reduction, and extending equipment lifespan.

[0004] However, this energy-saving and carbon-reducing SCR denitrification compressed air device still has some shortcomings in actual use. For example, it cannot adjust the compressed air supply according to actual needs, and one compressed air device can only supply a single production line, which is not adaptable enough. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, this utility model provides a technical solution: including a compressed air assembly 1, a switching assembly 2 is provided on one side of the front of the compressed air assembly 1;

[0023] The switching assembly 2 includes a switching housing 201, an inner groove 202 inside the switching housing 201, a servo motor 203 fixedly mounted on the bottom side of one side of the switching housing 201, a threaded crossbar 204 rotatably mounted on the bottom of the inner groove 202, a sliding groove 205 on the bottom surface of the inner groove 202, a slider 206 slidably mounted in the sliding groove 205, a switching slide plate 207 fixedly mounted on the top surface of the slider 206, a first vent 208 in the center of the front of the switching slide plate 207, second vents 209 on both sides of the switching slide plate 207, and a connecting... The switching slide 207 has an outer pipe 211 fixedly inserted into the center of its front and both sides. The front and back of the switching slide 207 are in contact with the inner wall of the slide groove 205. One end of the output shaft of the servo motor 203 is fixedly connected to one end of the threaded crossbar 204. The switching slide 207 is threaded onto the body of the threaded crossbar 204 and is connected to each production line as a backup machine. It can be switched to the required production line as needed. Specifically, the servo motor 203 is started. Under the action of the servo motor 203, the threaded crossbar 204 rotates. The rotation of the threaded crossbar 204 can drive the switching slide 207 to move within the inner groove 202.

[0024] By controlling the movement of the switching slide plate 207, the No. 1 air inlet 208 and the No. 2 air inlet 209 can be moved, so that the No. 1 air inlet 208 or a certain No. 2 air inlet 209 corresponding to the production line can be connected to the connection port 210. At the same time as the No. 1 air inlet 208 or a certain No. 2 air inlet 209 is connected to the connection port 210, the other end of the No. 1 air inlet 208 or a certain No. 2 air inlet 209 will also be connected to the inner port of a certain external pipe 211 provided on the front of the switching housing 201. After the connection is completed, the corresponding production line can be switched, and air can be supplied to the corresponding production line, which can effectively improve the adaptability of the compressed air device.

[0025] In this embodiment, the compressed air assembly 1 includes a mounting base 101, on which an air compressor 104 is fixedly mounted, and an air outlet 105 is provided on one side of the front of the air compressor 104.

[0026] Meanwhile, mounting side plates 102 are fixedly installed on the front and back bottom of the mounting base 101. Threaded openings are provided on both sides of the top surface of the two mounting side plates 102. A fixing screw 103 is threaded into each threaded opening. The fixing screw 103 can be connected to the threaded opening corresponding to the installation position, thereby enabling stable and convenient installation of the compressed air device.

[0027] The two No. 2 air inlets 209 are arranged at an angle and are symmetrically arranged, and the compressed air device can be switched to which production line it is connected to through the No. 2 air inlets 209.

[0028] The switching housing 201 is fixedly installed at one corner of the top surface of the mounting base 101, and one end of the air outlet 105 is connected to the connection port 210.

[0029] In summary, this energy-saving and carbon-reducing SCR denitrification compressed air device can move the No. 1 air inlet 208 and No. 2 air inlet 209 by controlling the movement of the switching slide plate 207. This allows the No. 1 air inlet 208 or a certain No. 2 air inlet 209 corresponding to the production line to connect with the connection port 210. At the same time as the No. 1 air inlet 208 or a certain No. 2 air inlet 209 connects with the connection port 210, the other end of the No. 1 air inlet 208 or a certain No. 2 air inlet 209 will also connect with the inner port of a certain external pipe 211 set on the front of the switching housing 201. After the connection is completed, the device can be switched to the corresponding production line and supply air to the corresponding production line. The compressed air supply can be flexibly allocated according to production needs, ensuring a sufficient supply of compressed air under abnormal operating conditions, and reducing energy consumption loss and equipment wear of the standby air compressor 104 under normal operating conditions due to frequent standby and loading states. This achieves the effects of energy saving, carbon reduction, and extending equipment life.
