Abstract

The present invention relates to a coating of the crude gas tract of a fly-stream gasification plant with a heat-resistant anti-stick layer. A fly-stream gasification device for a process that employs powdery or liquid fuels-where liquid fuels are to be understood as oils, or oils containing solids, and water or oil suspensions containing fuels ground to the consistency of dust or inorganic additives-at pressures of between ambient pressure and 8 MPa and gasification temperatures of between 1,200 and 1,900 DEG C., and which has a gasification means containing free oxygen, comprising a gasification chamber, a quenching device, and an element that belongs to the crude gas tract and ducts the crude gas, is embodied in such a way that an element ducting crude gas is made of heat-resistant carbon steel and furnished on surfaces in contact with the crude gas with an anti-stick layer able to withstand a temperature of 250 DEG C. for preventing the carbonates that form from sticking. Thereby, the quenching process can be carried out under a pH value greater than 6.5, cheap heat-resistant carbon steel can be used in the crude gas tract, and the cross section of the Venturi throat of a Venturi washer does not become smaller, such that the efficiency is reduced until the gasification process is stopped for purification.

Description

The coating that gas is disguised the raw gas passage of putting that flies with heat-stable anti-adhesion layers
Technical field
The present invention relates to a kind of be applicable to dust-like or liquid fuel and contain free oxygen gasifying medium operation fly stream (Flugstrom) gasification installation, wherein liquid fuel means oil or contains solid oil and water or oil and wear into the fuel of finely powdered or the suspension of inorganic mixture, its pressure between environmental stress and 8MPa, gasification temperature is 1200-1900 ℃, has the feature of claim 1 preamble.
Background technology
Reach in the gasifying process of 8MPa (80bar) at operating pressure, in another processing step, carry out gas sweetening through washing by the effusive raw gas of reactor/quencher (1) by steam-laden heat with full quenching.Be connected to from quencher in the pipeline (2) of washer (3,5), the pipeline (4) of washer neutralization itself from first washer to second washer, carbonate deposition appears on duct wall He in the washer.It is owing to have basic metal and exist basic metal caused as the raw gas composition in raw gas and carbonic acid gas thus in the ash of gasification substance (carbon, slurry or biomass) that this carbonate forms.
This settling is particularly at washer (3,5) under the situation of particularly using Venturi scrubber, can cause the cross section of Venturi throat to diminish in, stop transport to purify owing to the pressure-losses that increases that therefore causes forces plant efficiency to reduce up to gasifying process.
By some operation quenching technology can reduce the chemical process of carbonate formation or prevent the chemical process that carbonate forms under corresponding tart operation scheme in pH value＜6.5.But result that should the acidity operation scheme be since have high erosion rate acid corrosion and can not the inexpensive heat-resisting carbon steel of use.Generation need to use acid proof and therefore expensive material.
Summary of the invention
The purpose of this invention is to provide and a kind ofly fly gas makeup and put, they can be in pH value greater than 6.5 o'clock operation quenching technologies and need not the aforementioned stop time that purifies setting that is generally.
This purpose feature by its characteristic in by the described equipment of preamble feature of claim 1 realizes.
By the present invention, particularly Venturi tube and institute's connecting tube (3,4) apply with durothermic anti-adhesion layers to washcoated device (3,5).Exemplary chemical nickel, chemical nickel PTFE, fluoropolymer coating and the special-purpose enamel mentioned.This coating prevents the adhesion of the carbonate that forms.
With coated surface prevent to deposit created can be in the pH value prerequisite of 6.5 o'clock operation quenching technology.It goes back an advantage is to use the material of cheap heat-resisting carbon steel as preparing washing device (3,5) and pipeline (2,4).
The favourable expansion scheme of the object of the invention is listed in the dependent claims.
Following adjoint is to understand required scope the present invention is described in detail in detail with embodiment.
Description of drawings
Fig. 1 illustrates the gasification installation with full quenching.
Embodiment
Send into fuel and oxygen/steam to the top that flies the gas reactor, wherein in flame reactor, make the temperature of fuel between the pressure between the high pressure of environmental stress and 80bar (8MPa) and 1200-1900 ℃ issue the first portion oxidation.Fuel is to use dust-like or liquid fuel, and liquid fuel means oil or contains solid oil and water or oil and wear into the fuel of finely powdered or the suspension of inorganic mixture.
The gasifying gas of heat leaves gasification chamber with liquid slag, and draws off passage and slag by raw gas and draw off passage and arrive the quenching chamber, for cooling raw gas and slag spray into water in the quenching chamber by the quenching nozzle.Slag deposits is discharged under water and through the slag outlet.Be 200 ℃ through pipeline 2 with steam-laden attitude and temperature through the raw gas of quenching and leave the quenching chamber.
Raw gas continues conduction through the raw gas passage, and this passage is made of different parts, as 3 pipeline 2 from the quencher to the washer, from washer 3 to washer 5 pipeline 4, washer 5 itself and the Venturi throat when using Venturi scrubber.By the present invention parts of at least one conduction raw gas are set, parts a plurality of or that all conduct raw gas are mainly made as material by heat-stable carbon steel, and with the contact surface of raw gas on have can tolerate 250 ℃ of temperature the anti-adhesive coating to prevent the adhesion of formed carbonate.
