The present invention, relative to traditional sludge pyrohydrolysis technique, has the advantage that
1) raw sludge is directly processed, it is not necessary to reflux dilution.
General pyrohydrolysis technique is required to reflow process, to ensure the vapor absorption efficiency of subsequent handling, main If because sludge concentration height causes viscosity abruptly increase, reducing the mass transfer effect of steam and mud.And this technique In, steam gas distribution system set in former dredge pump can in pump suction chamber uniform gas distribution, set double spiral shells Rotation feeding system, can be sufficiently stirred for raw sludge, make mud, flash-off steam be sufficiently mixed mass transfer, improves Vapor absorption efficiency;The steam of non-absorption condensation is during passing through former pug storehouse sludge blanket, most of By former mud condensed absorbent.Improve the absorbance of flash-off steam the most to greatest extent.
Follow-up two-stage jet chimney mixing arrangement uses the most dynamically, rear static order, is mixed by first-stage dynamic After clutch, mud viscosity is substantially reduced, and reaches 5000~8000cp, is the mixing effect of two grades of static mixers Fruit provides guarantee.
2) power-equipment is few, and power consumption is lower.
Electrical equipment in general pyrohydrolysis technique has: former dredge pump, backflow water pump, hydrothermal reactor charging pump, Homogenizing/pulp mechanical agitator (or Hydraulic Circulation pump), hydrothermal reactor mechanical agitator etc..And this technique Electrical equipment be only former dredge pump, the power resources of remaining subsequent handling are former dredge pump and mud pressure itself, Unit power consumption is that conventional hot water solves about the 1/2 of technique.
3) control point is few, controls logic terse, and reliability is higher.
Control point in general pyrohydrolysis technique has: the control of Liquid level, temperature, Stress control, flow control System, time control etc., and each reactor to be required to arrange above-mentioned control chain, and general batch-type heat Hydrolysis process also relates to the control (according to time, liquid level, temperature, pressure etc.) of dozens of program-controlled valve, The pump simultaneously used needs to arrange the defencive functions such as pressure, flow, temperature, and whole system needs to arrange several Ten, the most up to a hundred control point, control complexity is high, once some control point break down can cause whole Cover system stops, poor reliability.
And the control point of this technique only has: chain, the hydro-thermal discharge that enter steam control valve and hydrothermal temperature are adjusted Chain, the one-level of joint valve and chain, the flash tank discharge regulation valve of hydro-thermal reaction pressure and flash tank liquid level are moved The time of state blender air bleeding valve controls, a total of 4 control point.Therefore, technique is more terse, reliability Higher.
4) number of devices is few, invests low, occupation of land province.
In general pyrohydrolysis technique, involved equipment has: former pug storehouse 1~2, former dredge pump 1~2, backflow (pulp is reacted for water pump 1~2, hydrothermal reactor charging pump 1~2, pulp Hydraulic Circulation pump 1~2 Device is without arranging during agitator), pulp reactor 1~2, hydrothermal reactor 2~8, flashing reactor 1~6 Platform etc..Meanwhile, the time of staying set by the general each reactor of pyrohydrolysis technique is 30~120min.
And the capital equipment of this technique is: former pug storehouse, former dredge pump, first-stage dynamic blender, two grades of static state Blender, steam jet ejector, fast-assembling pipe type water thermal reactor, flash tank.Wherein, former pug storehouse, former mud Pump, flash tank and common process equipment investment, take up an area essentially identical;Remaining first-stage dynamic blender, two grades Static mixer, steam jet ejector etc. are conduit fittings class, and volume is little, take up an area province;Fast-assembling tubular type hydro-thermal is anti- Answering device is vertical tube group, takes up an area and saves (the about floor space of 1 hydrothermal reactor of common process), meanwhile, Eliminate the equipment such as the pulp reactor of common process, hydrothermal reactor, hydro-thermal charging pump.This process equipment Investment is the 40%~50% of conventional thermal hydrolysis process.
5) continuous process, more superior.
The hydrothermal reactor collection of general batch-type hydrolysis process feeds, preheats, heats, reacts, discharge, treat Each operation such as machine is in one, and its capacity utilization is relatively low, and the real reaction time accounts for total residence time 1/5~1/3.Therefore result in gross investment, floor space etc. to be multiplied.
And this technique is continuous process, mud heating process is integrated in former dredge pump, first-stage dynamic blender, In two grades of static mixers, fast-assembling pipe type water thermal reactor is only the place of hydro-thermal reaction.Therefore, its equipment Capacity utilization is higher, is that a kind of investment is low, takes up an area province's optimum process.
