Description
Technical field
The present invention relates to a kind of rubber diaphragm sealed gas holder of two-part of regular polygon thin oil seal gas holder reconstruction.
Background technology
Many existing polygon thin-oil sealed gas tanks domestic at present have been stopped transport or " running in spite of illness ", and reason mainly has
Three aspects：The polygon thin-oil sealed gas tank that (1) 80 year and the beginning of the nineties build is older so far more than 20 years of operation
It is in bad repair；Before (2) 2008 years, the country build polygon thin-oil sealed gas tank be low-voltage cabinet (design pressure 8kPa with
Under), with the expansion of iron and steel enterprise's scale, ductwork pressure improves, and these low pressure polygon thin-oil sealed gas tanks can not be again
It is incorporated into the power networks；(3) polygon thin-oil sealed gas tank uses the piston seal method of thin oil and steel slide plate, to the essence of installation
Degree requires high, and for many polygon thin-oil sealed gas tanks because installation accuracy is inadequate, operation has piston guide wheel interim card, draining
The problems such as big is measured, after overhaul, these problems cannot still eliminate.
It is proposed and is reconstructed currently for the reconstruction problem of this kind of thin-oil sealed gas holder of the regular polygon to go wrong
Into the technology of unistage type rubber membrane sealed type gas holder, the technology has been applied in engineerings such as Zhong Tian steel plant at present, economical
Index and technical indicator are good, but the technology also has its limitation：(1) cabinet of loss holds more, with Changzhou Zhong Tian steel plant 10
Ten thousand m3Exemplified by the improvement project of regular polygon thin oil seal gas holder, its cabinet appearance for being transformed into the rubber diaphragm sealed gas holder of unistage type only has
7.3 ten thousand m3；(2) limitation of rubber membrane technology limits the thin-oil sealed gas holder of large-scale regular polygon and is transformed into unistage type rubber
Film closed type gas holder.For 24m or so, (foreign technology also only has 28m to the making length of current domestic rubber membrane, and price is domestic
More than 3 times of unit price), this length is carrying out 100,000 m3Gas holder had been used up when transforming it is ultimate attainment, and for 150,000 m3, 200,000 m3
The transformation of the thin-oil sealed gas holder of regular polygon far can not then meet that single hop cabinet transforms demand.
The content of the invention
