Abstract
The utility model relates to a gas distributor for a fluidized bed gasifier, comprising a gasifier cone, a nozzle arranged on the gasifier cone and communicated with a gas source, a ring pipe arranged on the lower end of the gasifier cone and communicated with the gas source, wherein the gasifier cone is provided with a central tube; the cone consists of a regular cone arranged on the upper part and an inclined cone arranged on the lower part; the control pipe can be arranged either on the inclined cone or on the regular cone. The utility model, by arranging the central tube on the cone of the gasifier, makes the central tube above a supporting point short, thereby overcoming the problem of 'big head and small end' and easy breaking of the central tube, reducing erosion effect the gas flow in the ring pipe on the central tube and the corrosion effect of the clinker on the external wall of the central tube. As a result, the use cycle of the gas distributor is improved greatly.
Description
Technical field
The utility model relates to a kind of gas distributor, particularly a kind of fluidized-bed gasification furnace gas distributor.
Background technology
For the fluidized bed coal gasifying process, gas distributor is a key part of fluidized bed coal gasifier, and it mainly acts on is to cause fluidisation, keep the interior material movement continuously of bed and make the gas uniform distribution.The structure formation of gas distributor is a lot, and the type of using on fluidized-bed gasification furnace also has a variety of, as porous template, nozzle type etc.
(patent No.: ZL200520079695.3) disclose a kind of fluidized bed gas sparger, it mainly is made up of grid distributor, pipe core and endless tube that the surface is provided with thermofin and wear-resistant pouring layer " a kind of fluidized bed gas sparger ".
(patent No.: ZL200520105814.8) disclose a kind of fluidized bed gas sparger, it mainly is made up of nozzle, pipe core and endless tube " a kind of fluidized bed gas sparger ".
More than the weak point of disclosed two kinds of gas distributors be that the pipe core of gas distributor is positioned at endless tube, the lime-ash in the outer wall of pipe core and the endless tube inwall makeup ring passage, vapourizing furnace discharges out of the furnace by the ring passage.Therefore, airflow scouring under the hot conditions and deslagging cause pipe core outer wall serious wear, and be very high to the requirement of pipe core material, the material price costliness.In addition, because the above straight length part of pipe core point of suppon is longer, there is the phenomenon of " top-heavy ", cause pipe core easily to fracture owing to vibrating in the operational process from point of suppon, requirement to the structure design of pipe core is very harsh, is unfavorable for the long-term operation of device.
Summary of the invention
The purpose of this utility model has been to provide the fluidized-bed gasification furnace gas distributor that a kind of fluidizing performance is good, life cycle is long, simple in structure, be convenient to maintain and replace.
For achieving the above object, the technical solution adopted in the utility model is: the endless tube that is connected with source of the gas that comprises the vapourizing furnace cone and be arranged on vapourizing furnace cone lower end, and on the sidewall of vapourizing furnace cone, also be provided with the nozzle that is connected with source of the gas, it is characterized in that: on the vapourizing furnace cone, also be provided with the pipe core that is connected with source of the gas.
Vapourizing furnace cone of the present utility model is made up of superposed right circular cone and the beveled cone that is positioned at the bottom; Pipe core is arranged on beveled cone or the right circular cone.
The utility model is arranged on pipe core on the cone, and is shorter more than the pipe core point of suppon, overcome the problem of pipe core " top-heavy ", frangibility.In addition, lime-ash is directly discharged out of the furnace by endless tube, greatly reduce air-flow in the endless tube under the hot conditions to pipe core wash away and lime-ash to the wearing and tearing of pipe core outer wall.
Description of drawings
Accompanying drawing is an one-piece construction synoptic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are described in further detail.
Referring to accompanying drawing, the utility model comprises by superposed right circular cone 5 and the beveled cone 4 that is positioned at the bottom forms vapourizing furnace cone 1, vapourizing furnace cone 1 is provided with the nozzle 2 that is connected with source of the gas, vapourizing furnace cone lower end is provided with the endless tube 6 that is connected with source of the gas, and pipe core 3 is arranged on beveled cone 4 or the right circular cone 5.
The utility model utilizes the fluidization principle, is that pure oxygen, carbonic acid gas and steam divide three the road to enter gas distributor from pipe core 3, endless tube 6 and nozzle 2 with the vaporized chemical that mixes, and makes the coal grain boiling fluidisation in the vapourizing furnace.Under the hot conditions that burning produces, the pyrolysis of coal, the redox reaction of breaking sticking and carbon take place in the contact of gas-solid two-phase thorough mixing, finally realize coal gasification.Lime-ash after the gasification discharges out of the furnace from endless tube 6.
The utility model is arranged on pipe core on the vapourizing furnace cone, and is shorter more than the pipe core point of suppon, overcome the problem of pipe core " top-heavy ", frangibility, and the maintenance of pipe core, change convenient.In addition, lime-ash is directly discharged out of the furnace by endless tube, reduced under the hot conditions air-flow in the endless tube to pipe core wash away and lime-ash to the wearing and tearing of pipe core outer wall.Therefore, improved the life cycle of gas distributor greatly.
