Background
The matched conveying pipe network for pulp and paper sewage treatment is mostly made of Q235 carbon steel, and the material is easy to be corroded to cause leakage in the use process due to the fact that conveying media contain high water soluble solids (DTS), such as resin, tannin, chlorophenol, organic sulfides, sulfate, hydrogen sulfide, methane and the like. The slurry and paper sewage treatment also has the characteristics of large water quantity, short system buffer time, long system downtime maintenance period, short time and the like, and causes production interruption caused by pipeline point corrosion, needs fire operation, needs material discharge, has low safety coefficient, long plugging working time and complex plugging process. The problems of material leakage, environmental influence and the like are always a difficult problem for restricting normal and stable production. The current common solution and method for this problem are as follows: 1) And (3) stopping the system: repair welding treatment is carried out after the pipeline is emptied and drained, and the defect that production is required to be interrupted and production stopping loss is caused exists; 2) And (3) a plug wedge jacking method: firstly, plugging holes by using a material with high toughness, fixing screw threads, pup joints or high-strength nuts (welding seams do not directly participate in plugging) in a welding mode after sand holes and the periphery are plugged, and then screwing the screw plugs or the nuts to meet the plugging requirement, wherein the defect that fire is required to be used for treatment exists, and the danger coefficient of a medium with combustible gas in a pipeline is high; 3) Drainage method: leading water flow at the leakage point to a controllable path, enabling the valve to be in an open state to play a role in backflow, then welding the pressure-resistant pipe sleeve around the leakage point, closing the valve after welding is finished to play a role in sealing, and aiming at the problem that the medium danger coefficient of combustible gas in a pipeline is high due to the fact that the sealing effect is not ideal if drainage is not smooth; more materials are leaked, and the risk of environmental damage is easily caused; 4) The sticking and supplementing method comprises the following steps: the adhesive is directly or indirectly blocked at the leakage part of the pipeline for sealing, so that the sealing effect is not ideal due to the defects, and the risk of secondary leakage exists; 5) And (3) welding and packaging: the method for sealing the leakage part in the metal cavity has the defects that the metal cavity is a nonstandard cavity and cannot be perfectly matched with the leakage stopping part, and the leakage stopping part has secondary leakage risk; 6) Twisting and sewing: the method for blocking the leakage point by extruding the soldering tin or the metal body around the leakage point by using the punch has the defects that the risk coefficient of the soldering treatment is high, and secondary leakage is easy to occur at the leakage point after the leakage is blocked; 7) The clamping method comprises the following steps: the method for stopping the sealing gasket at the leakage point by using the clamp has the defects of laborious operation, different stress of the leakage stopping part and different leakage risks at other parts; 8) The clamping method comprises the following steps: according to different positions of the leakage points, different clamps are selected, after the leakage points are installed, sealing agents are injected into the sealing cavity at a pressure higher than the pressure of medium leakage, the sealing agents are quickly solidified, a new sealing structure is built, the purpose of plugging is achieved, the defects are complex operation, and secondary leakage risks exist after plugging.
