Description

Technical Field

[0001] The invention relates to the technical field of orifice plate wire mesh laying, and in particular to a construction process for orifice plate wire mesh laying of fine desulfurization equipment. Background Art

[0002] The orifice plate cylinder of the fine desulfurization tower has an outer orifice plate diameter of 3.8 to 4 meters and an inner orifice plate diameter of 1.6 to 2.2 meters. The inner and outer orifice plates are concentrically mounted and have a height of more than 8 meters. The length of the orifice plate wire mesh is more than 7.5 meters. When the stainless steel wire mesh is laid on the orifice plate, the inner orifice plate is the wire mesh laid outside the cylinder, and the outer orifice plate is the wire mesh laid inside the cylinder (separated by a reinforced ring plate). When the orifice plate is installed vertically, the wire mesh will droop due to its large width and the influence of its own weight, causing the laid wire mesh to be wrinkled, which ultimately affects the laying quality. The use of this wire mesh sleeping process solution will avoid the occurrence of this phenomenon, while also avoiding high-altitude operations, improving the laying quality and safety.

[0003] In addition, after the inner and outer perforated plates are installed, the wire mesh is laid vertically, which requires a support frame. The space between the perforated plates is small, making it inconvenient to set up the frame and lay the wire mesh. The wire mesh laying efficiency is low and time-consuming. The wire mesh is wide and affected by its own weight, so the laid wire mesh will droop downward, causing the laid wire mesh to be wrinkled, affecting the laying flatness quality, and the safety factor for high-altitude operations is low. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, the invention provides a construction process for a perforated plate wire mesh berth of a fine desulfurization device.

[0018] Unfold the wire mesh along the laying direction to make the wire mesh fit the perforated plate;

[0019] Several groups of pressure strips are arranged along the laying direction of the wire mesh to ensure that the wire mesh and the perforated plate are completely fitted;

[0020] When the wire mesh is laid in a circle, an axial pressure strip is set at the starting point or key point of the connection.

[0021] In the above technical solution, the pressure strip can be a stainless steel pressure strip adapted to the shape of the orifice plate, or a strong magnetic stone.

[0022] In the above technical solution, the laying direction is always along the same direction.

[0023] In the above technical solution, after the wire mesh laying of an area is completed, the perforated plate is rotated to an appropriate position to rotate the unlaid area to a position convenient for the operator to operate.

[0024] In the above technical solution, the rivet tightening process is specifically as follows:

[0025] Install rivets in the pre-drilled rivet holes to secure the bead and wire mesh to the perforated plate.

[0026] In the above technical solution, the wire mesh is laid on the inner circumferential surface or the outer circumferential surface of the orifice plate.

[0028] Base;

[0029] A mounting frame, disposed on the upper surface of the base;

[0030] The roller assembly is rotatably connected to the mounting frame, wherein both ends of the orifice plate are placed on the roller assembly to complete the axial rotation process.

[0031] In the above technical solution, the roller assembly includes:

[0032] A rotating shaft, disposed on the mounting frame;

[0033] The roller is rotatably connected to the rotating shaft.
