Embodiment
For the present invention is become apparent, hereby with two preferred embodiments, and coordinate accompanying drawing to be described in detail below.
Affect that syngas cooler is long-term, efficient, the principal element of steady running, except with the operation condition of vapourizing furnace exist certain associated, also with syngas cooler in Dual-Phrase Distribution of Gas olid flow characteristics and the temperature distributing characteristic of high-temperature synthesis gas and lime-ash have very close relationship, the melting of often carrying because of high-temperature synthesis gas, semi-melting state ash solid impurity particle easily impact film-type water-cooling wall surface the phenomenons such as dust stratification, slagging scorification, stifled slag occur, and have had a strong impact on the operation stability of syngas cooler.Therefore, when vapourizing furnace operation operating mode is stablized, the water wall in necessary reasonable Arrangement syngas cooler, on the basis in maximum using syngas cooler space, optimize syngas cooler interior flow field structure, avoid the appearance of fouling and slagging situation on water wall.
Fig. 1 is a kind of radiation provided by the invention and convective heat exchange integral type syngas cooler schematic diagram, described a kind of radiation and convective heat exchange integral type syngas cooler comprise housing 16, membrane wall 14 is equipped with in housing 16 inside, slag bath 3 is arranged at housing 16 bottoms, housing 16 tops have synthetic gas entrance 1, and upper side has syngas outlet 5.Membrane wall 14 is cylinder-shaped and in cylindrical shell, forms center flow channels 2, forms annular space space 4 between housing 16 and membrane wall 14, and this annular space space 4 interior layout convection current screen formula water wall 15, arranges Quench gas/vapour entrance 9 on the top of membrane wall 14.
High temperature, high-pressure gasified product enter from the synthetic gas entrance 1 at water cooler top, after Quench gas/vapour Quench at Quench gas/vapour entrance 9 places, molten state ash solid impurity particle is solidified by Quench rapidly and converges at center flow channels 2, center flow channels 2 with air-flow along water cooler flows downward, while contacting bottom slag bath 3, most of grey solid impurity particle is caught and is removed by slag bath 3, synthetic gas is turned back and is entered annular space space 4 and upwards flow, after the further cooling of convection current screen formula water wall 15, from syngas outlet 5 outflows of top-side.
High pressure water enters from water wall water inlet 17, through absorbing the heat of membrane wall 14, is heated and converts high-pressure saturated water vapor to, by water wall water outlet 10, is discharged, and can be used for steam turbine generating or other process gass of preheating after overheated.The slag bath 3 of water cooler bottom is used for collecting the major part ash solid impurity particle that air-flow carries, and the water of slag bath 3 is entered by slag bath water inlet 18, from slag bath water outlet 19, discharges, and by pulp water, is circulated and is kept slag bath liquid level stabilizing.The lime-ash of slag bath 3 is discharged enter follow-up lock hopper after opening baffler 27 after.Raw gas through sensible heat recovery and rough purification enters downstream process flow process from the syngas outlet 5 of water cooler.
Because membrane wall 14 tops at water cooler inner core are provided with Quench gas/vapour entrance 9, therefore High Temperature High Pressure gasification product after entering water cooler by low temperature Quench gas/vapour Quench, temperature is reduced to rapidly below 900 ℃, thereby the grey solid impurity particle of molten state is solidified rapidly, and concentrate on center flow channels under the effect of converging of air-flow, reduced to greatest extent the probability that lime-ash deposits on membrane wall 14.In addition, owing to being provided with convection current screen formula water wall 15 in annular space space 4, synthetic gas sensible heat is further reclaimed, synthetic gas temperature further declines, and has improved the serviceability of useless pot system when having saved convection recuperator floor space.
Quench gas/vapour inlet duct 23 connects Quench gas/vapour entrance 9 by Quench gas/vapour entrance header 22.Quench gas/vapour entrance 9 is provided with 1～3 layer on membrane wall top, and Quench gas/vapour entrance 9 of every layer is evenly distributed along membrane wall 14 cylindrical shell circumference.This make high temperature, high-pressure gasified product on water cooler top by Quench gas/vapour rapid Quench more effectively, make slag obtain solidifying more rapidly, reduce the probability that it forms dust stratification, slagging scorification on water wall.
In conjunction with Fig. 3; owing to entering the synthesis gas flow of water cooler, carried a large amount of grey solid impurity particles, for preventing the jet diffusion of grey solid impurity particle, capable of regulating Quench gas/vapour entrance 9 directions; guarantee grey solid impurity particle therefrom heart runner flow downward, and directly do not contact membrane wall 14.Therefore, the Way in of Quench gas/vapour entrance 9 and center flow channels 2 axis directions form angle theta, the scope of this angle theta is: 0 75 ° of < θ <, preferable range is 45 ° of 5 < θ <.
Owing to having carried a large amount of grey solid impurity particles in air-flow secretly, for preventing that lime-ash from stopping up Quench gas/vapour entrance 9, in Quench gas/vapour total amount one, regularly guarantee suitable flow velocity, when setting Quench gas/vapour entrance 9 number, in order to prevent that Quench place from forming strong turbulent flow, its flow velocity is unsuitable too high, in the constant situation of controlled chilling gas/vapour entrance 9 diameters, the number of Quench gas/vapour entrance 9 is 4～80, and the scope of Quench gas/vapour inlet diameter is 10～150mm, and diameter preferable range is 50～100mm.
Refrigerant for Quench can be selected pump around circuit downstream low temperature clean synthetic gas or water at low temperature steam.If adopt pump around circuit downstream cleaning low temperature synthetic gas as Quench gas, the volumetric flow rate that Quench gas is selected accounts for 1/3rd of the total gas volume of outlet, also can adopt mesolow saturated vapor to carry out Quench, real needs amount can require to regulate according to subsequent technique.
In order further synthetic gas to be carried out to waste heat recovery, enter behind radiation waste pot annular space space 4, the convection current of arranging screen formula water wall 15 will play a role, because most of lime-ash is captured and removes at bottom slag bath 3, enter the lime-ash solids volume concentration that the synthetic gas in annular space space 4 carries secretly lower, and because temperature is lower than 700 ℃, stains cohesiveness and greatly reduce, therefore improved the internal space utilization ratio of water cooler.
In addition, in inner core membrane wall 14 inner sides, be provided with 4 soot blowers 13, sweep gas is blown into from sweep gas entrance 12, can effectively prevent ash deposition.In conjunction with Fig. 3, R is the distance of inner core membrane wall 14 and center flow channels 2 central axis, r is the line that inner core membrane wall 14 vertical components are mapped on point on center flow channels 2 central axis and inner core membrane wall 14 curved parts a bit topmost, whole circular arc type (R=r) or the parabolic type (R ≠ r) of adopting of synthetic gas entrance 1 designs, to reduce entrance jet recirculating zone.Synthetic gas entrance 1 outside, place of syngas cooler adopts flange 6 to be connected with vapourizing furnace, and housing 16 inner sides adopt refractory brick 7 to build by laying bricks or stones.The heat insulation packing space 21 in syngas cooler top can adopt mould material filling or fill high pressure nitrogen.
The present invention is suitable for the heat recovery of gasification product in conventional gasification Chemical Manufacture, and the sensible heat that is particularly useful for integrated combination cycle generating (IGCC) system gasification island gasification product is recycled.If syngas cooler of the present invention is applied to IGCC system, syngas cooler, by being arranged in the main therrmodynamic system of IGCC system, can be steam turbine power generation high pressure steam is provided.
