Problems solved by technology

[0003] However, at present, many existing polygonal thin oil-sealed gas holders in China have been out of service or "running with a disease". Has been in operation for more than 20 years and is in disrepair
(2) Before 2008, the polygonal thin oil-sealed gas cabinets built in China were all low-pressure cabinets (design pressure below 8kPa). With the expansion of the scale of iron and steel enterprises, the pressure of the pipe network increased. The cabinet can no longer run in parallel with the grid
(3) The polygonal thin oil-sealed gas cabinet adopts the piston sealing method of thin oil and steel slide plate, which requires high installation accuracy. Many polygonal thin-oil-sealed gas cabinets have piston guide wheel stuck, stuck, etc. due to insufficient installation accuracy. Problems such as large amount of oil leakage, after overhaul, these problems still cannot be eliminated
Although iron and steel enterprises recognize the advantages of single-stage rubber-sealed gas holders, if the polygonal thin-oil-sealed gas , not only the project time is long but also the project cost is very high

Embodiment 1

[0025] like figure 1 As shown, the existing regular polygonal thin oil-sealed gas cabinet includes a gas cabinet body 1, an internal hoisting cage 13, a temporary rescue device 14, an external elevator 15, an inlet and outlet pipe 16, an oil groove 17 at the bottom, and a piston 8. 8 includes the piston truss 81, oil groove support 82, piston oil groove 83, piston support bracket 84, piston bottom plate 85, thin oil-sealed gas cabinet sealing mechanism 86, etc. This kind of gas cabinet is a thin oil-sealed gas cabinet. If the cabinet body is greatly deformed, it will easily lead to reduced sealing effect or oil leakage. And for the regular polygonal thin oil-sealed gas holder that has been scrapped, if it is dismantled and then rebuilt a new gas holder, not only needs a large amount of funds, but also needs construction for a long time.

[0026] like figure 2 Shown: In the modification method of the regular polygonal thin oil-sealed gas cabinet provided in this embodiment, ...

Embodiment 2

[0035] On the basis of the above embodiments, a preparatory step is also included before step 1: stop production of the gas cabinet and perform gas replacement, and cut construction holes on the side wall of the gas cabinet body.

[0036] In this embodiment, construction holes are cut on the side wall of the gas cabinet body, and the construction holes can be used for the entry and exit of personnel, construction tools, and engineering materials, which facilitates the construction process.

Embodiment 3

[0038] On the basis of the above-mentioned embodiment, a bracket installation step is also included between the preparation step and step one: the piston bracket 18 is installed at a position corresponding to the edge of the one-piece gas cabinet piston 7, and the upper surface of each piston bracket is controlled to be in contact with the piston bracket. The lower chord contact of the piston truss.

[0039]In this embodiment, when the one-stage gas cabinet piston 7 is dropped, a piston support 18 is set at the position corresponding to the edge of the one-stage gas cabinet piston 7, so that the piston also keeps a certain distance from the bottom plate of the polygonal cabinet body for future maintenance when falling. Provide sufficient operating space for maintenance; in addition, it can also prevent the piston bottom plate from contacting the bottom plate of the gas cabinet body after the piston falls, and then the piston bottom plate and the gas cabinet body will be sucked ...

Abstract

The invention discloses a transformation method of a regular polygonal thin oil sealed gas cabinet. The transformation method comprises the following steps: a piston oil groove support and a piston oil groove of the regular polygonal thin oil sealed gas cabinet are dismounted; an inner cylinder is mounted; brackets are mounted and connected to a side plate and a stand column of the gas cabinet; the connected brackets are connected with the inner cylinder; a truss of a piston and a piton baseplate are adjusted according to the shape of the inner cylinder, so that the shape of the piston is matched with the shape of the inner cylinder; a piston fence is arranged on the piston to form a one-section rubber film sealed gas cabinet piston; piston sealing profile steel is arranged at the bottom end of the piston fence; inner cylinder sealing profile steel is mounted on the inner cylinder in the peripheral direction; and a rubber film is unfolded, and two ends of the rubber film are respectively connected with the inner cylinder sealing profile steel and the piston sealing profile steel. The transformation method renewedly uses a cabinet body of the wasted polygonal thin oil sealed gas cabinet, and is low in construction investment, short in construction time and higher in economic benefit.

Description

technical field [0001] The invention relates to a modification method of a regular polygonal thin oil-sealed gas holder. Background technique [0002] Regular polygonal thin oil-sealed gas cabinets are also called Mann-type (M.A.N) cabinets. Since Baosteel introduced polygonal thin-oil-sealed gas cabinets from Japan in 1979 to store blast furnace gas and coke oven gas, polygonal thin-oil-sealed gas cabinets It has developed rapidly in China and is widely used by various iron and steel enterprises. Before 2010, most of the thin oil-sealed gas holders built in China were polygonal thin-oil-sealed gas holders, and there were a large number of them. [0003] However, at present, many existing polygonal thin oil-sealed gas holders in China have been out of service or "running with a disease". It has been in operation for more than 20 years and is in disrepair. (2) Before 2008, the polygonal thin oil-sealed gas cabinets built in China were all low-pressure cabinets (design pres...
