Abstract
The utility model discloses a kind of with cold insulation structure at the bottom of the low-temperature storage tank tank of water-proof function, at the bottom of tank center region be staggered lay in strength foam glass tile, be staggered laying high-strength degree foam glass brick in the annular region strengthening concrete ring beam bottom, cover asphalt felt form watertightness barrier at all foam glass brick upper and lower surface spary adhesive bitument primers, increase spary adhesive bitument primer at the outer side surface of outermost high-intensity foam glass brick and the outer side surface of strengthening concrete ring beam and carry out water-proofing treating.Cold insulation Rotating fields at the bottom of the low-temperature storage tank tank of band watertightness barrier described in the utility model has that reliable performance, good water-proof effect, cost are low, short construction period and the easy advantage of work progress.
Description
Technical field
The utility model relates to the low-temperature storage tank storing Liquefied Hydrocarbon and LNG, is specifically related to low-temperature storage tank bottom configuration.
Background technique
Along with development and the requirement of sustainable economic development strategy to energy resource structure of petrochemical industry, as chemical industry base stock and the Liquefied Hydrocarbon (Liquefiedhydrocarbon) of New-type fuel and the status of LNG Liquefied natural gas (LiquefiedNatural Gas, hereinafter referred to as LNG) more and more important.The demand of domestic and international market to Liquefied Hydrocarbon and LNG storage facility progressively increases, and particularly has more demand to large-scale low-temperature storage tank.
Low-temperature storage tank is by outer tank cylindrical shell, and inner canister cylindrical shell, at the bottom of outer tank tank, at the bottom of inner canister tank, tank deck, the Cold-keeping Layer between interior outer tank forms.The cold insulation layer of low-temperature storage tank comprises tank deck Cold-keeping Layer, Cold-keeping Layer at the bottom of tank skin Cold-keeping Layer and tank.Wherein particularly Cold-keeping Layer at the bottom of tank, not only will support medium-weight in tank body self structure weight and tank, also will have efficient cold insulation performance, so have the structure of more complicated.
In the adiabatic work progress of low-temperature storage tank may the moisture of rain, humid air or bottom plain concrete screed-coat evaporation invade heat insulation layer at the bottom of inner canister after moisture can be made to freeze in running, cause heat insulation layer cold insulation effect to decline or lose.
Model utility content
The purpose of this utility model is to provide a kind of with cold insulation structure at the bottom of the low-temperature storage tank tank of water-proof function, to solve the technical problem that in large-scale low-temperature Storage Tank Construction and running, at the bottom of moisture intrusion tank, heat insulation layer causes heat insulation layer cold insulation effect to decline or lose.
The technical solution of the utility model is: a kind of with cold insulation structure at the bottom of the low-temperature storage tank tank of water-proof function, to it is characterized in that at the bottom of tank center region be staggered lay in strength foam glass tile, be staggered laying high-strength degree foam glass brick in the annular region strengthening concrete ring beam bottom, cover asphalt felt form watertightness barrier at all foam glass brick upper and lower surface spary adhesive bitument primers, increase spary adhesive bitument primer at the outer side surface of outermost high-intensity foam glass brick and the outer side surface of strengthening concrete ring beam and carry out water-proofing treating.
Technological scheme described in the utility model is passed through at foam glass brick surface spary adhesive bitument primer and is covered asphalt felt as watertightness barrier, realizes the isolation of cold insulation layer and air at the bottom of tank and keeps dry, making it have cold insulation effect efficient for a long time.Cold insulation Rotating fields at the bottom of the low-temperature storage tank tank of band watertightness barrier described in the utility model has that reliable performance, good water-proof effect, cost are low, short construction period and the easy advantage of work progress.
The tank volume that the utility model relates to is 10,000 ~ 26.5 ten thousand steres, and the storage temperature range related to is-198 to 45 DEG C.The cold insulation structure that the utility model provides is applicable to single appearance formula, double volume type and full appearance formula bimetal low-temperature storage tank, is applicable to prestressed reinforced concrete low-temperature storage tank simultaneously.
