Abstract
The utility model provides a new taper bottom structure of a water coal plasm pressuring gasification furnace, comprising a taper armor plate, a heat preservation layer, taper bottom bricks consisting of two circle firebricks, which are internal circle bricks and external circle bricks, a single taper bottom brick is a high chrome firebrick without a hook and a tongue. The internal circle bricks are comprised of trapezoid bricks R number 1 with square brackets, rectangle bricks S number 1 with the square brackets, and the square bricks T number 1 with the square brackets, the external circle bricks are comprised of pentagon bricks P number 1 with the square brackets, Q number 1 with the square brackets, and rectangle bricks r, Y number 1 with the square brackets, Y number 1 with the square brackets. A seam between the internal circle bricks and the external circle bricks is provided with right angle, the seam is 3 to 5mm, a the preventing gas walloping is filled in the seam. As the internal circle bricks and the external circle bricks are structure which can disassemble, when check the gasification furnace, the internal circle bricks and the external circle bricks can be changed together after changing the internal circle bricks for 2 to 3 times, which can save 50 percent of taper bottom bricks per year, greatly reduce the check work, save the construction cost, shorten the check time and improve the equipment utilization.
Description
Technical field
The utility model relates to a kind of texture improvement of coal water slurry pressurized gasifier, specifically, relates to a kind of novel awl bottom structure of coal water slurry pressurized gasifier vaporizer.
Background technology
In the prior art, the shell of coal water slurry pressurized gasifier is a steel plate, and operating pressure is 4.0Mpa, the high chromium firebrick of vaporizer liner of vapourizing furnace, brick, stack shell brick and key brick at the bottom of the reference cone.Every on awl end refractory brick all has ditch and tongue; the design of whole cone brick is whole; and all there is ditch to be connected between brick and the brick with tongue; awl brick work-ing life end is generally all about half a year; when the R relevant with internal diameter, S, T, r brick deteriorate 1/4 left and right sides; bore when internal diameter is greater than below metal chilling ring internal diameter at the end; no longer can protect the below chilling ring; awl end brick will be changed by overall pulling down; at this moment; the P of periphery, Q, R brick deteriorate and are less than 1/4, have just thrown away together when changing brick, cause the waste of about 3/4 brick.In addition, because every block of refractory brick all has ditch and tongue, all have ditch, tongue to be connected between brick and the brick, at ditch, when expand with heat and contract with cold in the tongue place, stress concentration is prone to fracture when temperature variation is big, shortened the work-ing life of refractory brick.
Summary of the invention
The utility model is in order to overcome the wasting phenomenon that awl end brick is changed in the prior art, improved the structure of monolithic awl end brick, brick structure at the bottom of the whole awl is divided into dismountable inner ring brick and outer ring brick, greatly reduce the cost of awl end brick maintenance, reduce maintenance workload and repair time, improved production efficiency.
The utility model is to realize like this, the novel awl bottom structure of this coal water slurry pressurized gasifier comprises brick at the bottom of taper steel plate, thermal insulation layer, the awl, brick is made of inner ring brick and outer ring brick two circle refractory brick at the bottom of being characterized in whole awl, and monolithic awl end brick is a high chromium firebrick of not being with ditch and tongue.
Inner ring brick of the present utility model is by trapezoidal brick R
1, rectangle S
1With square block T
1Constitute, the outer ring brick is by pentagon brick P

2Constitute.
Inner ring brick of the present utility model and outer ring brick to split be sewed with right-angled bend.
Split seam between inner ring brick of the present utility model and the outer ring brick is 3～5mm to the crack, fills anti-gas leakage material in the split gap.
Monolithic awl end refractory brick of the present utility model is not with the ditch tongue, make originally can only the whole awl of changing together at the bottom of brick change inner ring and outer ring two into partly, but inner ring easily deteriorate the part local replacing (account for the awl end brick gross weight 1/4), outer ring brick (account for awl end brick gross weight 3/4) replacing together after the inner ring brick is changed 2-3 time, save the consumption of awl end brick, greatly reduced production cost.Split between inner ring brick and the outer ring brick is sewed with two right-angled bends, fills anti-gas leakage material in the split seam, has guaranteed that the synthetic gas in the vapourizing furnace can not leak by gas blowby from brickwork joint.According to the thermal expansivity of awl end brick, inner ring brick and outer ring brick leave suitable gap when building by laying bricks or stones, the seam that promptly contracts the second month in a season, and the destruction of stress to awl end brick has prevented to expand with heat and contract with cold.
The utility model has following advantage compared with the prior art: one, the annual awl end brick 50% of saving greatly reduces production cost.Two, reduce maintenance workload, reduced the maintenance executive cost.Three, shorten the repair time, improved plant factor, increased the production time.
Now in conjunction with the accompanying drawings an embodiment of the present utility model is specified.
