Description
Technical field
The utility model relates to a kind of gasification Quench buck high pressure flash pressure relief buffering mechanism, be applicable to the grey water handing operation of dry coal powder pressure gasifying and water coal slurry pressure gasification, to pressure release and the buffering of High Temperature High Pressure Quench buck gas, liquid, solid three-phase before the gasification Quench buck high pressure flash tower.
Background technology
Coal gasification and then acquisition clean fuel or other elementary Chemicals have broad prospects in China, and for reaching the target of energy-saving and emission-reduction, the buck that vapourizing furnace produces need to carry out energy recovery and recycle.
Coal pressure gasification is that coal and oxygen or oxygen enrichment the incomplete combustion reaction occurs under pressurization and the condition of high temperature make high-temperature synthesis gas, and High Temperature Gas adopts chilling process directly and the water contact cooling, and the gas by chilling process is for the manufacture of carbon-chemical and synthetic ammonia.The advantages such as chilling process has less investment, be easy to operate and control are used general.
The High Temperature High Pressure buck that gasification Quench section produces (gas, solid), comprise the solid of coal gasification gas, coal, the liquid that the gasification Quench produces, need to reclaim heat through flashing tower, but high temperature, high pressure, the high solid buck of carrying the high rigidity solid particulate secretly directly enter flashing tower by pipeline, to being set in variable valve before the flashing tower and the flashing tower, antiscour spare causes serious erosive wear, cause maintenance of equipment frequent, impact is normally produced, and reduces the work-ing life of equipment.High Temperature High Pressure buck (gas, solid) is the difficult problem of puzzlement system long-term operation to the erosion of variable valve and flashing tower always.Current in the urgent need to researching and developing a kind of High Temperature High Pressure buck (gas, solid) that can effectively solve to the pressure relief buffering mechanism of the erosion of flashing tower and angle valve, to ensure the safe operation of gasification ash water system long period.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for prior art, provide a kind of can avoid High Temperature High Pressure buck gas-liquid-solid three-phase to the erosion of flashing tower, alleviate the wearing and tearing to angle valve, guarantee the gasification Quench buck high pressure flash pressure relief buffering mechanism of system's long-term operation.
For solving the problems of the technologies described above, the utility model gasification Quench buck high pressure flash pressure relief buffering mechanism is achieved by following technical scheme: comprise water inlet pipe, diffuser tube, tank body, wash away platform, removable shrouding, rising pipe form, described water inlet pipe is arranged on the top of tank body; One end of water inlet pipe connects the described upper end that is trapezoidal cone shape diffuser tube, and the lower end of described diffuser tube connects tank body, arranges in the lower end of tank body and washes away platform, sets out water pipe above the exterior side wall of tank body.Design diffuser tube, surge tank help the flow velocity moment reduction of buck, and are cushioned in tank body and energy dissipating, and can bear the erosion that solid content is high in the buck, hardness is high, flow is large, wash away platform detachable replacing is set.This apparatus structure deft design, flow velocity by steady reduction buck, clear up buck and carry energy, change flow velocity and the fluidised form of Quench buck (gas, solid), protecting high temperature high pressure Quench buck (gas, solid) is to the erosion of flashing tower and angle valve effectively, thus solved that the flashing tower maintenance is frequent, work-ing life short problem.
Arrange in the bottom of described tank body and to wash away platform, described wash away platform be positioned at described removable shrouding above, described removable shrouding is bolted on the bottom of tank body.
The described platform that washes away adopts 150-250mm rich chromium cast iron or ceramic material.Rich chromium cast iron is the abbreviation of high chromium white antifriction cast iron, is a kind of excellent property and be subject to the special wear-resistant material of paying attention to.It is with the wear resistance more much higher than steel alloy, with toughness, the intensity more much higher than general white cast iron, simultaneously it also has good high temperature resistance and corrosion resistance concurrently, produce in addition convenient, cost is moderate, and is described as one of the best abrasive wear resistant weld deposit material in the present age.
Described tank body inner side-wall is coated with the thick coat of silicon carbide of 5-6mm/lining pottery.Silicon carbide (SiC) is to be that raw material forms by the resistance furnace pyrotic smelting with quartz sand, refinery coke (or coal tar), wood chip.Corrosion-resistant, high temperature resistant, the characteristics such as intensity is large, heat conductivility is good, shock resistance that silicon carbide has, silicon carbide can be used for various smelting furnace linings, High-temp. kiln member, carborundum plate, liner plate, strut member, saggar, silicon carbide crucible etc.
The caliber of described rising pipe is less than the diameter of described tank body, and the caliber of described rising pipe is greater than the caliber of described water inlet pipe.The caliber of top rising pipe is greater than the caliber of bottom rising pipe.Water exit position is divided into the flow velocity moment reduction that two parts of two outlet on top and bottom pipe help to realize buck, and its middle and upper part rising pipe is mainly used in the discharge of buck liquid phase, and the bottom rising pipe more is the discharge for the buck solid liquid phase.
The project organization of the diffuser tube of described buck high pressure flash pressure relief buffering mechanism, tank body, rising pipe; the fluidised form formation and modification; can realize flowing into the moment shunting of material; change runner and the fluidised form of gas-liquid-solid three-phase in the Quench buck; make that grey water flow velocity steadily reduces, the clearing up of energy; effectively protecting high temperature high pressure Quench buck (gas, solid) is to the erosion of flashing tower, protection flashing tower and angle valve.
The utility model is by arranging a gasification Quench buck high pressure flash pressure relief buffering mechanism, effectively avoided High Temperature High Pressure buck (gas, solid) to the erosion of flashing tower, alleviated the wearing and tearing of angle valve.In view of the needs of China's modernization construction energy-saving and emission-reduction, this utility model has wide market outlook, and its release must bring good economic benefit and social benefit.
