5) with the exhaust collection of incinerator, after chemical washing, enter bacteria bed and process, tail gas rear discharging up to standard.
Compare with method with existing sludge treatment device, the utlity model has following outstanding advantages and technique effect:
1. adopt 2 stirrings, the 1st stirring mixes the mud of water ratio≤80% with properties-correcting agent, after stirring, make it become the following mud compound of water ratio 40%; The 2nd stirring adds medium coarse sand, after stirring, makes it become the following mud compound of water ratio 35%; After be placed in factory building 3 ~ 5 days, during can produce low temperature fermentation (approximately 40 ~ 60 ℃ of temperature) its moisture is volatilized naturally, its water ratio is down to below 30%; Through the extruding of extrusion machine twice, its water ratio is down to below 25% again; Then enter molding device and carry out moulding (sludge calorific value after moulding is 400 ~ 600 kilocalories approximately); Then enter incinerator and burn, burning process need not to add any fuel; Recrement after burning is surplus 10% left and right (not containing compound) only.Recrement be as compound reuse and mud mix (the residue recrement can be done the building materials utilization), and so recycle reaches the effect of waste recycling, has realized sludge treatment energy-saving, minimizing, innoxious, resource utilization.
2. adopt power-assisted ejection ram formula ball press or asymmetric spheroid ball press to carry out moulding, the demoulding to the mud fragment, efficient is high, effective.According to the character of mud, because mud is comprised of the reactive monomer cell, contain the organism more than 50%, and water ratio is high, light specific gravity, be a kind of pseudo-plasticity gel.Be difficult to moulding, and the difficult demoulding after moulding, easy broken, resistance to compression extreme difference, traditional ball press can't satisfy this processing requirement, therefore the utility model adopts power-assisted demoulding nest axle piston ball press, when material entered in pair roller ball mould, nest axle piston rod inwardly shrank under pressure; During until the demoulding, along with pressure relieve, nest axle piston rod outwards ejects under the effect of spring, impels the smooth demoulding of sludge ball when material forming, solved a demoulding difficult problem and ball-type full, be difficult for brokenly, can satisfy the requirement of this technique.
3. adopt elevating screws formula feeding unit, and it is set directly at the incinerator top, due to mud spheroid intensity difference, easily broken, after using lifting, spiral to add the structure of slideway, sludge ball can slowly enter in burner hearth along spiral slide, and along with the increase of material in stove, slideway progressively rises, and therefore can guarantee that material is not broken, evenly distributes in burner hearth, improve the efficient of charging, and improve ventilation effect.This device plays keying action in burning process, because mud spheroid physique is light and soft, is unable to undergo gravity and impacts, and blanking skewness, broken material easily stop up the gap between spheroid, causes burning inhomogeneously maybe can not burning.Adopt the blanking of this device, spheroid is not broken, the spheroid gap is large, ventilation effect good, guarantee the perfect combustion of material energy, improve combustionvelocity.
4. due to the conjuncted incinerator of employing with the hollow angle of repose fire grate of multilayer tracheae, so the cross section of furnace grate tube is trilateral, and the furnace grate tube bottom is provided with production well, and air can be evenly dispersed in burner hearth.Only need add first outside external compound, the recrement reusable edible after burning, burning process integrates mummification, pyrolysis, carbonization, burning, completes in same body of heater, has improved greatly the thermo-efficiency of body of heater, and burning process need not to add any fuel.Equipment is few, technical process is short, and treating processes adopts totally enclosed, does not produce dust, really reaches the effect of waste recycling, has realized sludge treatment energy-saving, minimizing, innoxious.Recrement after burning is as the Main Function of compound: approximately 80 ~ 120 ℃ of oven-fresh recrement temperature, and with the mud mix, utilize the temperature of recrement can evaporate and adsorb moisture in mud after crushing.The hot high efficiency of body of heater, rational in infrastructure, burn thoroughly, normal pressure operation, long service life, safe and reliable to operation.
5. the proportion of the effect that adds medium coarse sand: ⑴, increase material is beneficial to moulding; ⑵ the conductive force in, burning process; ⑶ with the sludge creation friction, destroy the mud cell walls in, stirring, extrusion process, force out water in the table of mud (except adding in proportion for the first time, according to the demoulding and the moulding situation of spheroid, a little both replenish can).
6. sludge ball enters incinerator through feeding unit and burns, and during burning on fire first, burns layer and is positioned at bottom of furnace body, along with the passing of the time of burning, burns layer and moves to the body of heater middle part on gradually, and the slag of bottom of furnace body after burning made cooling layer; The hot gas (temperature of burning layer reaches 850 ~ 1000 ℃) that burns layer generation when burning is directly dried the mud on upper strata.According to the speed control of burning, bottom is slagged tap, burn in the middle level, feed in raw material in the upper strata, so circulation, burns incessantly.Recrement after burning (except original compound) only remains 10%.Recrement enters first technique again and mud mixes, and unnecessary recrement can be used as the building materials utilization.Owing to being block the burning, so the dust that burning process produces is few, if any a small amount of dust, is also most ofly adsorbed by upper baking zone in burner hearth.
