Specific embodiment
Explanation is further explained to the utility model below in conjunction with the accompanying drawings:
Referring to Fig. 1, the lower section of vaporizer 1 of gasification furnace 8 is shock chamber 6, and the upper and lower part wall of shock chamber 6 is respectively equipped with conjunction
Into gas outlet 4 and Heisui River outlet 5.The top of shock chamber 6 is provided with the lower cinder notch 7 of vaporizer 1, the lower connection Quench of cinder notch 7 pipe 3, institute
The internal diameter for stating Quench pipe 3 is 1.6~3.2 times of the internal diameter of lower cinder notch 7.The lower end of Quench pipe 3 is located at below liquid level, the Quench pipe 3
The top and middle part of inwall are uniformly provided with multiple chilling rings 2 connected with shock chilling medium import 11, on the chilling ring 2 circumferentially
Upper strata discharge outlet 9 and lower floor's discharge outlet 10 uniformly are provided with, lower floor's discharge outlet 10 is attached to the wall of Quench pipe 3 vertically downward
On face, the upper strata discharge outlet 9 diagonally downward, with the wall of Quench pipe 3 in 30 °~75 ° of angle a.The chilling ring 2
Position of the aperture of discharge outlet according to chilling ring 2 on Quench pipe 3 from top to bottom reduces step by step.
The discharge outlet aperture of the chilling ring 2 of the superiors is 4.0~5.5mm, and the spray of undermost chilling ring 2 goes out
Oral pore footpath is 1.5~3.0mm.
The course of work:
High-temperature synthesis gas that the vaporizer 1 of gasification furnace 8 is produced and lime-ash enter Quench pipe 3 by lower cinder notch 7, chilled water by
Shock chilling medium entrance 11 enters ring sparger 2, and two strands of subsequent Quench moisture sprays from ring sparger 2, and one sprays from upper strata discharge outlet 9
Go out, form the drop of atomization, mixing is contacted with the crude synthesis gas of high temperature, acutely exchanged heat, chilled water is come from by gasification absorption
The substantial amounts of heat of crude synthesis gas, significantly reduces the temperature of synthesis gas, meanwhile, the lime-ash in synthesis gas is fallen by cooling down
Enter the bottom of shock chamber 6.Another burst of chilled water sprays from lower floor's discharge outlet 10, is flowed down along Quench pipe, forms one layer of uniform liquid
Film, is prevented from synthesis gas and the directly contact of Quench pipe 3 and produces the hot-spot to cause Quench pipe to damage, on the other hand, Quench
Water flows down along Quench pipe 3 can prevent the lime-ash in synthesis gas from sticking to Quench inside pipe wall, make so as to play protection to Quench pipe 3
With.The region of violent heat exchange is carried out at the 0.5~2.5m of top of Quench pipe 3 for high-temperature synthesis gas and chilled water, due to this Quench dress
Put a diameter of lower cinder notch of Quench pipe 1.6~3.2 times, increased residence time of the synthesis gas in Quench pipe, in Quench pipe
In the presence of sufficient blending space, the effect of mass transmitting between synthesis gas and chilled water can be strengthened, make full use of the gasification latent heat of water,
So as to reduce the consumption of shock chilling medium.Crude synthesis gas after cooling enter below the Heisui River liquid level of the lower section of shock chamber 6, and from Quench
The bottom periphery of pipe 3 is upwardly into shock chamber's gas-phase space, due to synthesis gas and Heisui River directly contact, can again serve to cooling
Effect, while carrying out preliminary clean result to the lime-ash in synthesis gas, eliminates the bulky grain lime-ash in synthesis gas, reduces
The dustiness of syngas outlet.Enter next from syngas outlet 4 by the synthesis gas after cooling down and primary wash
Operation.Wash the Heisui River for producing and then enter black water treatment system from Heisui River outlet 5.
The utility model is lowered the temperature using ring sparger 2 to synthesis gas Quench, and the water smoke of ejection fills very much with the contact of synthesis gas
Point, the latent heat of process water gets the maximum use, and can make Quench discharge reduction more than 25%.Simultaneously because ring sparger 2 sprays
Go out one water to be flowed down along Quench pipe, form liquid film, Quench pipe can be played a good protection, extend making for Quench pipe
Use the life-span.Chilled water usage amount can be reduced using the utility model, the scale of follow-up black water treatment system is reduced, so as to reduce
Investment and operating cost, the internal circulating load for reducing process cycles buck, saving energy consumption.
