To facilitate an understanding of the present invention, a dry reactor air duct air-sweeping device will be described more fully below with reference to the accompanying drawings. The preferred embodiment of the dry reactor air duct air sweeping device is shown in the attached drawings. However, dry reactor air duct air-sweeping devices may be implemented in many different forms and are not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "mounted on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the dry reactor air duct sweeping device is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

As shown in fig. 1 and fig. 2, an embodiment of the present invention provides a dry reactor air duct air sweeping apparatus, including an air blowing device 11 and an air delivery pipe 2, where the air delivery pipe 2 includes a plurality of segments of universal bamboo joint pipes 20 connected in sequence; the blowing device 11 comprises an air compressor 11, a hose 12 and an air gun 13 which are connected in sequence, and a universal bamboo joint pipe 20 at the tail section of an air conveying pipe 22 is in ventilation connection with an air outlet of the air gun 12. The universal bamboo joint pipes 20 connected in sequence are used as gas transmission pipes, so that the requirements of tightness and support can be met, and abnormal shaking can not occur under the effective gas outlet pressure; utilize the characteristic that universal bamboo joint pipe 20 can moderate degree be crooked, send into the wind channel of reactor with gas-supply pipe 2, send compressed air to the wind channel of reactor through gas-supply pipe 2 in to can realize the direction regulation of certain degree in the wind channel, carry out the accurate air sweep of impurity and dust to the wind channel corner.

Generally, as shown in fig. 2, an outer cover 200 and a rain shield 300 are disposed outside a dry reactor body 100 of a dc converter station for blocking dust, sun and rain, the rain shield 300 is located above the dry reactor body 100, and an air duct 1001 of the dry reactor body 100 is vertically disposed, so that an entrance of the air duct 1001 above is blocked by the rain shield and the outer cover 200, and an entrance angle close to 90 degrees is presented in an entrance direction. At the moment, at the inlet of the air duct 1001, the air delivery pipe 2 is combined by adopting the universal bamboo joint pipe 20, so that a user can moderately bend the air delivery pipe 2 to enter the air duct 1001 from the upper part of the air duct for cleaning; after entering the air duct 1001, the user can slightly move the air gun 13 or the air pipe 2 part at the inlet of the air duct 1001 front, back, left and right to finely adjust the exhaust direction of the air pipe 2, so as to perform accurate air sweeping of impurities and dust at the corners in the air duct 1001.

Further, as shown in fig. 3, the universal bamboo joint pipe 20 includes a plurality of bamboo joint pipe bodies 21 which are sequentially and tightly connected, and each bamboo joint pipe body 21 includes a spherical head 211 and a body tail 212 which are integrally formed; an air flow channel 213 is arranged in the spherical head part 211, and a spherical cavity 2121 for spherically hinging the spherical head parts of the adjacent bamboo joint pipe bodies 21 is concavely arranged on the end surface of the tail part 212 of the body; the spherical cavity 2121 is communicated with the airflow channel 213, so that the high-pressure airflow passes through the airflow channel 213. The close connection among the bamboo joint pipe bodies 21 is that the spherical head 211 at the back is mechanically pressed and connected in the spherical cavity of the adjacent bamboo joint pipe body 21 for spherical hinge joint, so that the spherical head 211 and the spherical cavity are tightly combined, and the gap at the hinge joint of the spherical head 211 and the spherical cavity can be basically ignored, thereby avoiding air leakage; after the spherical head 211 is tightly combined with the spherical cavity, a certain friction force exists between the spherical head 211 and the spherical cavity, and abnormal shaking cannot occur under the effective air outlet pressure; by virtue of the spherical head 211 and the spherical cavity being spherically articulated, moderate bending between adjacent tube bodies 21 can be achieved at the spherical articulation.

Specifically, the body tail 212 of the bamboo joint pipe body 21 can be used as the air inlet direction of the air conveying pipe 2, and the spherical head 211 of the bamboo joint pipe body 21 can be used as the air outlet direction of the air conveying pipe 2, so that the skirt edge of the body tail 212 is in smooth contact with the air channel, and the air conveying pipe 2 can move forward in the air channel more smoothly. Further preferably, the bamboo joint pipe body 21 is made of nylon, and as the surface of the dry-type reactor including the surface of the inner wall of the air duct is coated with anti-pollution flashover coatings such as RTV or PRTV, the resistance along the surface of the reactor keeps better insulation performance, and the coating on the surface of the inner wall of the air duct is fragile and not easy to supplement, the bamboo joint pipe body 21 made of nylon can meet the requirements of tightness and support, and can well avoid the point of damaging the coating of the air duct.

Further, as shown in fig. 3, an annular engaging cavity 214 is formed at the connection between the spherical cavity 2121 and the airflow channel 213, so that when two adjacent bamboo joint pipe bodies 21 are bent, airflow can be facilitated to enter the airflow channel 213 from the spherical cavity 2121. Specifically, when the air flow passage 213 provided in the spherical head 211 is communicated with the spherical cavity 2121, since the inner diameter of the air flow passage 213 is smaller than that of the spherical cavity 2121, the connection between the air flow passage 213 and the spherical cavity 2121 is generally at a right angle, and the high-pressure air flow is somewhat blocked. Therefore, the right-angled portion is cut from the spherical cavity 2121 to the inside of the air flow channel 213 to form the annular engaging cavity 214, so that the high-pressure air can smoothly flow through the annular engaging cavity, and the ventilation is smoother. Preferably, the circular cutting range of the annular connecting cavity 214 can be set according to the maximum bending angle between adjacent bamboo joint pipe bodies 21, as shown in fig. 3, when the rear spherical head 211 is pressed into the spherical space of the front body tail 212 ', a part of the lower part of the spherical head 211 is still remained outside the spherical space of the body tail 212' to provide a certain range of motion, so that the bamboo joint pipe bodies 21 can be bent appropriately and a certain degree of direction adjustment is realized; when the bottom of the tail part 212 'is bent to contact the top of the tail part 212, which is the largest bending angle between the two bamboo joint pipe bodies 21, the edge of the air flow channel 213 in the spherical head part 211 is just overlapped with the edge of the annular joining cavity 214' in front, so that the high-pressure air flow smoothly enters the air flow channel 213 'from the air flow channel 213 along the inner wall of the annular joining cavity 214'.

Further, as shown in fig. 4 and 5, the universal bamboo joint pipe further comprises a hollow butt joint female joint 3 and a hollow butt joint male joint 4, wherein a butt joint groove 32 is formed inwards on one end face of the hollow butt joint female joint 3, the shape and the structure of the butt joint groove 32 are the same as those of the spherical cavity 2121, and the butt joint groove 32 is tightly connected with the spherical head 211 of the bamboo joint pipe body 21 at the head end of the universal bamboo joint pipe 20; a butt joint convex block 41 is formed outwards on one end face of the hollow butt joint male head 4, the shape and the structure of the butt joint convex block 41 are the same as those of the spherical head 211, and the butt joint convex block is tightly connected with a spherical cavity 2121 of the bamboo joint pipe body 21 at the tail end of the universal bamboo joint pipe 20; the other hollow end surface of the hollow butt joint female head 3 is detachably connected with the other hollow end surface of the hollow butt joint male head 4. Because the reactor wind channel is long and narrow, length can reach 10 meters at most, for making the transportation of gas-supply pipe 2 and store convenient, and avoid gas-supply pipe 2 overlength and fifty percent discount deformation, through female head 3 of cavity butt joint and the public head 4 pre-installation crimping of cavity butt joint at the both ends of universal bamboo joint pipe 20, make the female head 3 of cavity butt joint and the public head 4 of cavity butt joint and the both ends zonulae occludens of universal bamboo joint pipe 20, when the wind channel to the overlength, can be quick dock a plurality of universal bamboo joint pipe, satisfy the wind channel cleaning demand of multiple dry-type reactor.
