Therefore, the fixing device for the middle row member of the male tower of the fine treatment regeneration system comprises a reinforcing plate, a supporting member, a middle row member and lining rubber, wherein the reinforcing plate is welded on the inner wall of the male tower, the supporting member is welded on the reinforcing plate, the middle row member is connected with the supporting member through a bolt, and the lining rubber is coated on the reinforcing plate and the supporting member.
According to some embodiments of the utility model, the stiffener plate and the support member are both of hastelloy C-276 alloy.
According to some embodiments of the utility model, the stiffening plate has a size of 16cm by 16 cm.
According to some embodiments of the utility model, the reinforcement plate is welded to the wall of the male tower in a full-width manner.
According to some embodiments of the utility model, a double-sided full weld is used between the stiffener and the support member.
The embodiment of the utility model at least has the following beneficial effects:
1. the bolt holes are not lined with rubber, the rubber lining area is reduced, and the defect that the bolt holes are easy to expand due to long-term friction, extrusion and vibration caused by rubber lining is overcome.
2. The reinforcing plate and the supporting member are made of Hastelloy C-276 alloy, and are extremely resistant to hydrochloric acid corrosion, so that the service life is obviously improved compared with that of the integral rubber lining.
Additional aspects and advantages of the utility model will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the utility model.

Referring to fig. 1, a fixing device for a middle row member of a male tower of a fine processing regeneration system comprises a reinforcing plate 100, a supporting member 200, a middle row member 300 and a lining rubber 400, wherein the reinforcing plate 100 is welded on the inner wall of the male tower, the supporting member 200 is welded on the reinforcing plate 100, the middle row member 300 is connected with the supporting member 200 through a bolt, and the lining rubber 400 covers the reinforcing plate 100 and the supporting member 200.
The reinforcing plate 100 and the supporting member 200 both adopt Hastelloy C-276 alloy, the Hastelloy C-276 alloy belongs to nickel-molybdenum-chromium-iron-tungsten series nickel base alloy, and the reinforcing plate 100 and the supporting member 200 are made of Hastelloy C-276 alloy materials, so that the reinforcing plate can be used in acidic content liquid of the anode tower for a long time, and the corrosion resistance strength is improved.
In the present embodiment, the size of the reinforcing plate 100 is 16cm × 16 cm.
The fixing method of the fixing device of the component organ in the positive tower of the fine treatment regeneration system comprises the following steps:
a. cutting and taking down a fixed support configured in the factory of the male tower, removing lining glue 400 of a male tower wall 101 of the fixed support part, and polishing until a metal surface is exposed;
b. welding a reinforcing plate 100 on the polished metal surface of the male tower wall 101, welding a support member 200 on the reinforcing plate 100, and connecting a middle row member 300 on the support member 200 through bolts;
c. the reinforcing plate 100 and the support member 200 are covered with the lining rubber 400, and the screw holes between the support member 200 and the middle row member 300 are not treated with the lining rubber 400.
