But low-temperature zone, operating temperature is 230 ± 30 DEG C, so the top half of down-comer is also chronically at 1300 ± 100 DEG C
In high-temperature synthesis gas and slag adverse circumstances, it is easy to be burnt, influence the long-term operation of gasification furnace.
Mainly cooled down by inner surface of the chilling ring to down-comer in existing coal gasifier, Quench liquid by Quench liquid into
After water pipe enters shock chamber, by drain annular space along decline pipe internal surface decline, water membrane is formed in decline pipe internal surface, is closed
It exchanges heat when passing through down-comer at gas with moisture film, realizes the humidifying cooling to synthesis gas and slag, since chilling ring is under
Drop and form moisture film on the inside of pipe, moisture film fluctuate or the bad working environments that wreck under, it is uneven to also result in study of water film distribution, especially
It is the relatively thin position meeting flash evapn of moisture film, causes corresponding down-comer exposure under high temperature environment, down-comer is easy to appear
The phenomenon that modification, burn-through, down-comer is caused to damage.
Utility model content:
The purpose of this utility model is to provide a kind of on down-comer forms the device of inside and outside biliquid film, avoids down-comer
Burn the chilling device of the coal gasifier down-comer of damage.
The utility model is implemented by following technical solution: the chilling device of coal gasifier down-comer, includes down-comer, swashs
Cold ring, water spray endless tube, the water inlet of the chilling ring are connect with Quench liquid pipe road, the water inlet and flushing water of the water spray endless tube
Pipeline connects, several are uniformly equipped on the outer wall of the down-comer and fixes device, the water spray endless tube passes through the fixation
Device is bonded fixation with the down-comer, and the water spray endless tube pipe face adjacent with the down-comer is equipped with uniformly densely covered spray
The angle a of water hole, the central axis of the hole for water spraying and the down-comer is 30 °~60 °.
Further, the fixed device includes angle bar, pipe collar, the right-angle side and the down-comer of the angle bar
Outer wall be fixedly connected, the water spray endless tube is fixedly connected by the pipe collar with a right-angle surface of the angle bar.
Further, the water spray endless tube is divided into three sections, passes through method between every two sections of adjacent water spray endless tubes
Orchid is fixedly connected.
The advantages of the utility model: the utility model is one water spray endless tube of increase on the basis of existing chilling ring, is led to
The combination for crossing chilling ring and endless tube of spraying water, forms inside and outside biliquid membrane structure on down-comer, realizes the dual guarantor to down-comer
Shield, under inner wall liquid film wave or the bad working environments to wreck, outer wall liquid film can play the role of it is certain cool, guarantor
Down-comer is protected not because of deformation caused by high-temperature synthesis gas and slag or ablation damage.
