Method for transforming polygonal thin oil sealed dry gas holder to double-section rubber film sealed dry gas holder

Abstract

The invention relates to a method for transforming a polygonal thin oil sealed dry gas holder to a double-section rubber film sealed dry gas holder. The method comprises the following steps: 1) structural parameters of the traditional polygonal thin oil sealed dry gas holder serve as reference to calculate main structural parameters of the double-section rubber film sealed dry gas holder to be newly built; 2) a piston, a sealing device, an oil pump station and a holder volume indicator of the traditional polygonal thin oil sealed dry gas holder are disassembled; 3) a piston, a T baffle plate and a T baffle plate bracket of the double-section rubber film sealed dry gas holder to be newly built are mounted; and a lap of circular inner connecting side plates is mounted in a side plate area capable of being touched by an outer rubber film; and 4) an inner rubber film, an outer rubber film, a leveling device and a holder volume indicator of the double-section rubber film sealed dry gas holder to be newly built are mounted. The method saves the engineering cost and the engineering time, and is convenient for construction, high in efficiency and excellent in practical effect.

Description

technical field [0001] The invention belongs to the field of gas cabinets, and in particular relates to a method for rebuilding a polygonal thin oil sealed dry gas cabinet into a double-stage rubber membrane sealed dry gas cabinet. Background technique [0002] Gas cabinets are widely used in the storage of industrial and civil gas. At present, the mainstream gas cabinets in my country include polygonal thin oil sealed dry gas cabinets, round thin oil sealed dry gas cabinets and rubber membrane sealed dry gas cabinets. There are also circular dry oil-sealed dry-type gas holders and wet-type gas holders. Among them, due to the rubber membrane-sealed dry-type gas holders, the construction cost is low, the manufacturing and installation are convenient, the operation and maintenance are simple, the process is mature, the operating cost is low, and it is suitable for many applications. It is widely used in metallurgy, chemical industry, city gas and other industries in our country....

AI Technical Summary

Problems solved by technology

At the same time, many polygonal thin oil-sealed dry-type gas tanks built in the early stage have problems such as high operating cost, poor gas storage effect and high frequency of overhaul due to their long service time.

Therefore, it is an effective method to save costs and prolong the working life to transform the polygonal thin oil-sealed dry-type gas holder into a double-stage rubber membrane-sealed dry-type gas holder. The method of double-stage rubber membrane-sealed dry-type gas holder is simply to remove the original polygonal thin-oil-sealed dry-type gas holder, and then build a double-stage rubber-membrane-sealed dry-type gas holder at the original site. This method only saves land. But the original construction materials were wasted, and more engineering time and cost were invested
