In the industry production such as petrochemical industry, chemical industry, metallurgy, can produce much waste gas, in waste gas, contain a large amount of carbon dioxide gas, if do not recycled, enter atmosphere, can produce greenhouse effect and affect atmosphere environment.By cryogenic technology by CO wherein
2purified, purified, liquefied, thereby met national product and living needs, the pure CO after liquefaction
2liquid deposits basin in, to meet the demand of different industries.
For cryogenic technology purifying and liquefying CO
2the low-pressure carbon dioxide storage container of system is to determine according to a whole set of cryogenic technology cellular system configuration requirement, serve a unit of this system process, principal mode has vacuum-powders insulation basin, the adiabatic basin of polyurethane foam, installs refrigerator basin additional.Carbon dioxide kow-pressure basin is based on advanced technology, cost aim low, safe and effective, that be convenient to promote is innovated.
Carbon dioxide kow-pressure is mainly used in storing for a long time liquid CO
2occasion, be a kind of refrigerator that installs additional, adopt the novel basin of polyurethane foam thermal insulation.This basin is mainly used in fire protection sector, it is that carbon dioxide is stored in the storage container with insulation heat insulating construction with liquid form, makes in basin the temperature of carbon dioxide maintain all the time-17.8 ℃ of left and right, pressure maintain about 2.2MPa by cooling machine set.While having fire, by a series of actuators, liquid carbon dioxide is transported to scene of fire, by shower nozzle, discharges, implement fire extinguishing.
Low-pressure carbon dioxide storage container is due to CO
2pressure store is low, storage volume is large, and occupation area of equipment is little, blow-off velocity is fast, cost is low, the advantage such as pollution-free, and the place application high at fire hazard rating, protective area quantity is many, protective area area is large is more and more extensive.
The quality of low-pressure carbon dioxide storage container performance directly affects the performance of whole system.When the heat insulation effect of basin is bad, cooling machine set frequent starting, has increased rate of fault, and consume larger energy, increased operating cost, shortened the working life of cooling machine set, what tradition adopted is polyurethane on-the-spot foam, adopt people's tool and mould to control, foam-in-place, foams inhomogeneous, insulation layer thickness is thick, poor insulation property, outer alclad skin, earthquake-resistant moisture-proof weak effect; Filling rate≤95% of cryogenic liquid tank, top is gas-phase space; Background Conventional chiller units evaporator coil adopts single long loop configuration, is arranged in inner barrel middle and upper part major part and is immersed in liquid, the condensation of gas weak effect to cylindrical shell evaporated on top; According to the physical property of carbon dioxide, at pressure, during lower than 0.512MPa, liquid carbon dioxide directly changes into solid-state.Conventional security device adopts safety valve use in parallel with rupture disk, can effectively avoid inner core superpressure, once but rupture disk explosion, inner core pressure reduces rapidly, uncontrollable, thus it is solid-state to cause liquid carbon dioxide to change into, is difficult to cleaning and safeguards.
Summary of the invention
For the defect existing in prior art, the utility model provides a kind of carbon dioxide kow-pressure basin, its high insulating effect, and safety coefficient is high and be convenient to install.
Concrete technological scheme is: a kind of carbon dioxide kow-pressure basin, comprise inner core, shell, cooling machine set evaporator coil and safety installations, casing is located between inner core outside and shell and inner core and is provided with thermal insulation layer, shell one end is provided with the balance port that is communicated with inner core, fill mouthful, sewage draining exit and safety installations, the shell the other end is provided with manhole, shell upper end is provided with the exhaust port being communicated with inner core, cooling machine set evaporator coil is uniformly distributed in the top in inner core, and described safety installations is safety valve in parallel.
Described shell below is provided with chassis.
Described inner core is Q345DR cryogenic material, and inner core cross section is oval.
Described shell is that Q235A steel plate is made.
The utility model cost is low, standard according to JB/T4731 < < steel horizontal vessel > > designs, adopt Double-layer liner structure, high insulating effect, thereby improve the condensation efficiency of cooling machine set, reduce power consumption; Cooling machine set evaporator coil is arranged at the top in inner core, by the steam-condensation of evaporation, is effectively liquid, has improved the condensation efficiency of cooling machine set; The safety installations that safety valve in parallel forms can effectively be avoided the formation of solid carbon dioxide.
