The bottom of the main steel frame 100 is a top beam 110, and the top beam 110 provides a suspension pivot for the support platform 200.

The supporting platform 200 is located below the top beam 110, the supporting platform 200 is formed by assembling a plurality of sub-platforms 210, the supporting platform 200 is used for supporting the catalyst, the sub-platforms 210 are generally made of profiles, and the types of the profiles are not limited.

Of course, the support platform 200 is required to be formed with corresponding through holes for the threaded segments 320 to pass through.

The prop nut 400 is engaged with the threaded section 320 and an upper surface of the prop nut 400 abuts against a lower surface of the support platform 200 such that the support platform 200 is suspended by the topside beam 110, the hanger bar 300 and the prop nut 400.

Compared with the prior art, the supporting platform 200 of the suspension type SCR reactor is formed by assembling a plurality of sub-platforms 210, so that each sub-platform 210 is small in size, conveniently enters the reactor, is assembled inside the reactor, and is convenient to install. Meanwhile, the lower portion of the suspension rod 300 of the suspended SCR reactor is a threaded section 320, so that the entire support platform 200 can be changed in height due to the position of the support nut 400, thereby achieving height adjustability.

In order to realize the connection between the polished rod section 310 and the top beam 110, in some embodiments, as shown in fig. 4, two mounting plates 111 are disposed on the top beam 110 at an interval, each of the two mounting plates 111 is provided with a first through hole, the upper end of the polished rod section 310 is provided with a hanging plate 330, each of the hanging plates 330 is provided with a second through hole, the second through hole is opposite to the first through hole, the hanging plate 330 is located between the two mounting plates 111, and the connection is realized through a pin 112 passing through the first through hole and the second through hole and the mounting plates 111, so that the connection between the hanging rod 300 and the top beam 110 is realized through the pin 112, the installation is convenient, and the operation is convenient.

The sub-platform 210 is made of a profile, typically a frame structure. In order to assemble the supporting platform 200, in some embodiments, as shown in fig. 5, the sub-platforms 210 are made of channel steel, connecting through holes are formed in the side walls of the sub-platforms 210, the side walls of adjacent sub-platforms 210 are opposite to each other, the connecting through holes are aligned, and the adjacent sub-platforms 210 are assembled by bolts 211 penetrating through the connecting through holes.
