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

[0027] like figure 1 As shown, the existing regular polygonal thin oil-sealed gas tank includes a cabinet body 1, a hanging cage 13, a temporary rescue device 14, an external elevator 15, an inlet and outlet pipe 16, a bottom oil groove 17 and a piston 8; the piston 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. The polygonal thin oil-sealed gas cabinet is sealed by thin oil, which has high requirements on the working temperature. At the same time, if the side plate of the cabinet body is greatly deformed, the sealing performance will be reduced for a long time, and the oil leakage will be serious. As for the polygonal thin oil-sealed gas holders that have been scrapped or are about to be scrapped, if the gas holders are rebuilt after dismantling, a lot of money and time need to be invested.

[0028] like Figure 2-5 As shown, the single-sta...

Embodiment 2

[0034] On the basis of the above-mentioned embodiments, several piston guide wheels 11 are arranged respectively along the circumferential direction of the piston at the upper end and the lower end of the piston fence 72, and the piston guide wheels 11 include a guide wheel support connected with the piston fence 72 And connect the spring roller with the piston guide wheel support.

[0035] The guide wheel support and the piston guide wheel 11 of this embodiment can make the piston flexibly contact with the inner cylinder when it drifts, instead of rigid collision, and avoid damage to the rubber membrane 5 due to the rigid collision between the piston and the inner cylinder.

Embodiment 3

[0037] On the basis of the foregoing embodiments, a piston support 18 is provided on the bottom plate of the polygonal cabinet, and the piston support 18 includes four legs and a piston support crossbeam arranged on the four legs, and the piston support 18 The outer column stands in the bottom oil ditch of the regular polygonal thin oil-sealed gas tank, and the inner column stands on the bottom plate steel plate; the legs include four columns, connecting rods connecting the four columns, and the two ends are respectively connected to the columns and The diagonal brace connected by the rod, the two ends of the beam of the piston bracket are respectively connected with the upper ends of the two supporting legs, and the piston brackets are arranged along the circumferential direction of the piston.

[0038] In this embodiment, a piston support 18 is arranged at the bottom of the polygonal cabinet, so that the piston also keeps a certain distance from the bottom plate of the polygo...

Abstract

The invention discloses a single-stage rubber membrane sealed gas holder reconstructed from a regular polygonal thin oil sealed gas holder. The single-stage rubber membrane sealed gas holder comprises a polygonal holder body, a circular piston arranged in the polygonal holder body, as well as a sealing mechanism arranged between the polygonal holder body and the circular piston, wherein a plurality of connecting brackets and an inner cylinder connected with the connecting brackets are arranged in the polygonal holder body; an inner cylinder sealing steel section is arranged on a lateral plate of the inner cylinder in the circumferential direction of the inner cylinder; the circular piston comprises a circular piston baseplate, a truss arranged on the circular piston baseplate and a piston fence connected with the truss; a piston sealing steel section is arranged at the edge of the circular piston baseplate; the sealing mechanism comprises a rubber membrane and a corrugated plate; the two ends of the rubber membrane are respectively connected with the inner cylinder sealing steel section and the piston sealing steel section in a sealing manner; the distance between the bottom end of the inner cylinder and the bottom of the polygonal holder body is not greater than the height of the rubber membrane; and the distance between the top end of the inner cylinder and the bottom of the polygonal holder body is not greater than the height of the piston fence. The single-stage rubber membrane sealed gas holder provided by the invention is low in investment, short in construction period and considerable in economic benefit.

Description

technical field [0001] The invention relates to a single-section rubber membrane sealed gas cabinet reconstructed from a regular polygonal thin oil sealed gas cabinet. 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 Ch...
