The purpose of this utility model is: propose a kind of device removing vapourizing furnace synthetic gas flying dust, removes synthetic gas flying dust.
The purpose of this utility model is realized by following technical proposals:
A kind of device removing vapourizing furnace synthetic gas flying dust, comprise the vaporizer of vapourizing furnace, also comprise the radiation formula that be communicated with airtight with vaporizer to give up pot, the described radiation formula pot that gives up is provided with syngas outlet and slag-drip opening, inwall is provided with shock chamber's protection screen, inside is provided with radiation formula Quench pipe and cyclonic separator, and the slag bath to be communicated with described slag-drip opening, described radiation formula Quench pipe top connects gasification chamber outlet, bottom extends above described slag bath, some described cyclonic separators are uniform along described radiation formula Quench pipe lower, outer perimeter, each Cyclone outlet is by being communicated to described syngas outlet around the synthetic gas fairlead of radiation formula Quench pipe, ash tube bottom each cyclonic separator extends above described slag bath.
In such scheme, at the cyclonic separator of synthetic gas radiation waste pot internal layout some amount, in order to separating synthetic gas flying dust.During operation, crude synthesis gas mixes liquid slag and comes downwards to radiation waste pot by gasification chamber outlet through radiation formula Quench pipe, and through preliminary cooling, the block slag of solidification directly falls into slag bath, the synthetic gas (temperature is about 750-800 DEG C) being mingled with flying dust then enter be arranged in radiation waste pot inside cyclonic separator in carry out gas solid separation, separated synthetic gas enters follow-up flow process from syngas outlet, and isolated flying dust falls into slag bath by separator bottom ash tube, is discharged together with block slag by slag-drip opening.This patent, not only can reclaim the high temperature sensible heat of high-temperature synthesis gas, and enters the synthetic gas being through deliming of follow-up flow process, effectively can avoid the generation of follow-up flow process dust stratification and synthetic gas channel blockage.
As selection, in hook-shaped bending bottom described ash tube.
As selection, described shock chamber protection screen is also furnished with Quench spout.
In such scheme, Quench spout, shock chilling medium can be water spray, also can be the synthetic gas of re-injection after cooling, in order to regulate (or cooling) synthetic gas temperature, makes it the requirement reaching cyclone inlet temperature.
The main scheme of aforementioned the utility model and each further selection scheme thereof can independent assortment to form multiple scheme; be the utility model can adopt and claimed scheme: as the utility model; each selection can select arbitrary combination with other; those skilled in the art can understand there is multiple combination according to prior art and common practise after understanding the present invention program; be the claimed technical scheme of the utility model, do not do exhaustive at this.
The beneficial effects of the utility model: compared with prior art, this patent at the cyclonic separator of synthetic gas radiation waste pot internal layout some amount, in order to separating synthetic gas flying dust.This patent not only can reclaim the high temperature sensible heat of high-temperature synthesis gas, and enters convection current and to give up the synthetic gas being through deliming of pot heat exchange, effectively can avoid the generation of fouling of heating surface and synthetic gas channel blockage in useless pot operational process.Meanwhile, because synthetic gas is through ash disposal, hardly containing ash content, negligible to the wearing and tearing of follow-up convection heating surface, pipe wall thickness can be reduced, improve design gas velocity, strengthen heat exchange, the heat interchanging area needed for minimizing; Pipe does not have pickup and dust stratification, can reduce tube spacing, make compact arrangement of equipment, reduces cost; Reduce the top blast ash that is heated, not only can arrange sootblower less, all right predigested running, saves operation, maintenance cost.
