Description

Permanent brackets and rubber-membrane-sealed gas cabinets fitted with permanent brackets

technical field

The utility model relates to a gas cabinet used for gas recovery in iron and steel enterprises, in particular to a permanent bracket and a rubber membrane sealed gas cabinet equipped with the permanent bracket.

Background technique

As a necessary equipment for the comprehensive utilization of gas recovery in iron and steel enterprises, the gas cabinet plays an important role in the low-carbon economy.

At present, domestic rubber membrane sealed gas holders are divided into single-stage seal and two-stage seal; the single-stage seal has only one pressure, which is balanced with the weight of the piston, counterweight and process equipment; the two-stage seal gas storage has Two pressures, that is, one pressure when the piston rises, and one pressure when the piston drives the T-shaped baffle to rise. No matter the single-stage type or the two-stage type, there are a large number of temporary pillars for the piston. The function of the temporary pillars is to make the temporary pillars pass through the pistons and prop up the pistons when the bottom plate or the piston plate is overhauled, forming an inspection space of about 1m under the piston plate. . The temporary support of the piston is divided into two parts: one is the peripheral support of the piston; the other is the central support of the piston. The surrounding pillars of the piston are borrowed from the two zipper hoists on the circular track supported by the annular walkway on the top of the piston baffle to lift the peripheral pillars at symmetrical points, and then pass through the concrete retaining wall and support on the bottom plate of the gas cabinet, which is a semi-mechanized operation. The central pillar of the piston is manually installed, and then covered with a sealing cover to prevent the piston from leaking.

The number of central pillars of the piston is quite large. Taking ^a 50,000 m ³ rubber membrane sealed gas tank as an example, there are about 150 central pillars. As the capacity of the gas tank increases, the number of pillars also increases. Membrane-sealed gas cabinets will reach more than 300. The installation and removal of piston pillars, on the one hand, requires a lot of labor; on the other hand, because the bottom plate is spherical arched, the lower end of the temporary pillars needs to be cut arcs, and the arcs must be aligned during installation. These pillars, It is very difficult to achieve each alignment. If the alignment is inaccurate, the bottom plate of the gas holder and the piston will be subjected to uneven force locally, resulting in damage, thus bringing certain hidden dangers to the safe operation of the gas holder. Even, in order to reduce the workload, some enterprises let the piston run with these pillars, but the impact on the concrete dam wall of the piston and the damage to the maintenance pillars are not small, and the safety hazard is even more prominent.

All in all, installing and removing the piston access strut is a labor-intensive and time-consuming operation. This backward mode of operation obviously does not meet the requirements of high efficiency and labor saving in the current era, and it is imperative to improve it.
