Description
Technical field
The present invention relates to the remodeling method of a kind of regular polygon thin-oil sealed gas tank.
Background technology
Regular polygon thin-oil sealed gas tank is also known as graceful type (M.A.N type) cabinet, introduce after polygon thin-oil sealed gas tank is used for storing blast furnace gas and coke-stove gas from Baosteel 1979 from Japan, polygon thin-oil sealed gas tank is developed rapidly at home, commonly used by each iron and steel enterprise.Before 2010, the thin-oil sealed gas tank overwhelming majority of domestic construction is polygon thin-oil sealed gas tank, large number of.
But, current domestic a lot of existing polygon thin-oil sealed gas tanks have been stopped transport or " running in spite of illness ", reason mainly has three aspects: more than (1) 80 year and the polygon thin-oil sealed gas tank 20 years of operation the most built the beginning of the nineties, long neglected and in disrepair.Before (2) 2008 years, the polygon thin-oil sealed gas tank of domestic construction is low-voltage cabinet (below design pressure 8kPa), along with the expansion of iron and steel enterprise's scale, ductwork pressure improves, and these low pressure polygon thin-oil sealed gas tank cabinets cannot be incorporated into the power networks again.(3) polygon thin-oil sealed gas tank uses thin oil and the piston seal method of steel slide plate, high to the required precision installed, a lot of polygon thin-oil sealed gas tanks are inadequate due to installation accuracy, there is the problems such as piston guide wheel card pauses, dredge oil amount is big in operation, after overhaul, these problems still can not get eliminating.
Unistage type rubber seal moulded coal gas holder, compared with thin-oil sealed gas tank, has the many merits such as adaptation medium kind is many, the piston speed of service high (handling capacity is big), operating cost are low, is the trend of domestic gas chamber development.Although the advantage of iron and steel enterprise's accreditation unistage type rubber seal moulded coal gas holder, if but will stop transport or the polygon thin-oil sealed gas tank of " in spite of illness run " and basis overall pulling down reconstruction thereof are unistage type rubber seal moulded coal gas holder, not only engineering time length and also engineering cost is the highest.
Summary of the invention
For the problems referred to above, the present invention provides the remodeling method of the regular polygon thin-oil sealed gas tank that a kind of engineering cost is low.
For reaching above-mentioned purpose, the remodeling method of regular polygon thin-oil sealed gas tank of the present invention, it is characterised in that: comprise the steps:
