Description
Technical field
The utility model relates to a kind of synthetic furnace, the Two-in-One Graphite Synthetic Furnace of by-product two kinds of pressure rank steam while of particularly relating to a kind of.
Background technology
Some gases are by releasing a large amount of combustion heat during conbustion synthesis and forming high-temperature gas, and the temperature of such as conbustion synthesis HCl gas can reach 1800 ~ 2500 DEG C, synthesis P
2o
5gas temperature can reach 1000 DEG C.When utilizing this synthesis gas, join a water cooler after adopting synthetic furnace (or combustion tower) in early days to reduce gas temperature (such as dropping to 40 DEG C even lower).The corrodibility that the acidic solution tool formed because above-mentioned synthesis gas is dissolved in the water again is stronger, the graphitic synthetic furnace that therefore thermal conductivity and erosion resistance are all remarkable is just applied rapidly.Last century, the eighties was promoted more rapidly after starting that synthesis and cooling two equipment are merged into an equipment, practises be called two-in-one synthetic furnace in China.Thereafter advantage and the flash evaporation technology of graphite high heat conductance is utilized again very soon, the above-mentioned combustion heat is passed to the circulating hot water in the outer steel shell of graphite component (stove cylinder or heat transfer block) periphery by graphite wall, make it heat up into superheated water, be recycled in flash tank flash to saturated vapor for.So far by vapor pressure all < 0.6MPa of graphite wall heat-obtaining by-product.For improving byproduct steam pressure, the hypomere stove cylinder that last century, the eighties just developed graphite HCl synthetic furnace uses steel pipe manufacture instead with the two-in-one stove of the graphite of byproduct steam, and its most high yield steam pressure reaches 1.6MPa.But vapor pressure during all above-mentioned graphitic synthetic furnace byproduct steams only has a pressure rank, because of the two-in-one stove of byproduct steam both domestic and external, except " two sections of heat-obtaining type byproduct steam Two-in-One Graphite Synthetic Furnace " patented technology (ZL201220097176.X) of Shan Jian company, all only one section of heat-obtainings in synthetic furnace, namely except the upper ignition furnace of France is except the graphite block section heat-obtaining of bottom, other down-firing stove complete only from graphite-made or steel synthetic furnace cylinder section heat-obtaining with byproduct steam, be not suitable for going out two other saturated vapors of pressure stage from an above-mentioned heat-obtaining position by-product.
But only there is following shortcoming in the saturated vapor of a by-product rank: (1), as vapor pressure < 0.8MPa, its application surface is relatively little, and can not be grid-connected; (2) when vapor pressure higher (especially the middle pressure of vapor pressure >=1.6MPa), the heat of the temperature then leaving heat furnace cylinder in the stove in a large number still synthesis gas of higher (the HCl gas temperature such as leaving steel stove cylinder section during byproduct steam 1.6MPa pressure can > 800 ~ 1000 DEG C) not only can not be recycled, and will increase the consumption of water coolant.
Therefore, for solving the problem, spy provides a kind of new technical scheme.
Utility model content
The Two-in-One Graphite Synthetic Furnace of by-product two kinds of pressure rank steam while that the utility model providing a kind of.
The technical solution adopted in the utility model is:
The Two-in-One Graphite Synthetic Furnace of by-product two kinds of pressure rank steam while of a kind of, this synthetic furnace comprises bulb socket from the bottom to top successively, hypomere graphite furnace cylinder section, lower heat-obtaining section, upper heat-obtaining section and upper cover section, on the top of synthetic furnace, rupture disk is installed, upper heat-obtaining intersegmental part is provided with graphite heat exchange block, outer steel shell is provided with in the outside of upper heat-obtaining section, described graphite heat exchange block is along vertical core direction circulated gases, lateral aperture circulation cycle water, the hollow chuck of described lower heat-obtaining section is connected with flash tank respectively with the hollow chuck of upper heat-obtaining section, the steam simultaneously exporting two kinds of pressure can be distinguished, described hypomere graphite furnace cylinder section comprises hypomere graphite furnace cylinder and outer steel shell thereof.
Further, described lower heat-obtaining section is made up of stage casing graphite furnace cylinder and outer steel shell.
Further, described lower heat-obtaining section is steel heat transfer stove cylinder, and this steel heat transfer stove cylinder is the longitudinal circumferential row column welding of steel pipe.
Further, in the outer steel shell of described stage casing graphite furnace cylinder, pass into hot water, logical hot water in the outer steel shell of described upper heat-obtaining section.
Further, described upper heat-obtaining section comprises graphite furnace cylinder and is enclosed within the upper furnace tube shell of graphite furnace cylinder outside and graphite heat exchange block and is enclosed within the outer steel shell of graphite heat exchange block outside.
The beneficial effects of the utility model are: adopt heat-obtaining section differing temps hot water respectively lower heat-obtaining section, on heat-obtaining section hollow chuck in pump circulation to absorb the combustion heat of synthetic gas, be transported in flash tank after forming superheated water in the enclosure and flash to saturated vapor, because stage casing graphite furnace cylinder section (lower heat-obtaining section) displaced radiant heat and the high temperature heat by conduction of the high combustion gas of temperature simultaneously, thus the heat content of shell internal recycle hot water and temperature higher and the temperature (pressure) of byproduct steam can be improved, thus expand use range and can be grid-connected when needed.And although the synthetic gas temperature of walking out middle stove cylinder section reduces greatly, but still have hundreds of degree, when increasing the graphite heat exchange block section on upper furnace tube and continuing to reclaim this heat, because heat transfer block section heat interchanging area has 10 ~ 25 times of stove cylinder section, be again that material thermal conductivity reaches three times of carbon steel, the impregnated graphite manufacture of stainless about six times, thus the heat recuperation of logarithm Baidu atm number synthesis gas is most suitable scheme.In view of in synthetic gas, heat content greatly reduces, and wishes that the synthetic gas temperature of discharging reduces as far as possible, thus takes this section of by-product lower pressure steam more reasonable.While raising byproduct steam pressure, significantly improve energy-saving effect.
