Description

A kind of waste and the innoxious minimizing recycling treatment process system of industrial sludge
Technical field
The present invention relates to a kind of sludge and offal treatment technique, in particular to a kind of waste and industrial sludge are innoxious Minimizing recycling treatment process system.
Background technique
With the continuous development of China's industry, industrial enterprise is increasing, and the industry that Industrial Wastewater Treatment station generates is dirty The disposition of mud is just becoming the problem of large- and-medium size cities have to face.There are burning, landfill and heap to the processing mode of sludge at present Fertilizer.Because industrial sludge is containing toxic organic compound, heavy metal and pathogenic microorganism etc., it is not available composting process and carries out innoxious place Reason.Landfill process disposes that usual stable period is longer, if landfill area is without reasonably selecting and the antiseepage of science, controlling flood, take precautions against natural calamities and build If being then easy to the problems such as causing leachate contamination underground water and landslide, explosion, and sludge landfill takes up a large area, for Some land resources large size city in short supply, the practicability of Sludge landfill just constantly decline.And meeting is commonly burned because of comburant Expect that moisture causes greatly incomplete burning, burning difficulty big (need to add combustion adjuvant), burning to be difficult to control, generate a large amount of two after burning The disadvantages of disliking English pollution environment occurs.
With the continuous promotion of living standards of the people, industrial enterprise is increasing, and waste yield is also on straight line It rises, as consciousness of its people to environmental protection gradually increases, how to realize that waste is economical and practical, innoxious, recycling treatment It is one and needs the problem of facing.
Summary of the invention
In order to overcome the shortcomings of existing burning process, a kind of waste and the innoxious minimizing resource of industrial sludge are now provided Change treatment process system, which, which has slight pollution industrial sludge and waste, is directed to sexual clorminance, and has occupied area It is small, operation energy consumption is low, sludge and waste handle simultaneously, are innoxious, minimizing, recycling, can low energy consumption reach national row The advantages of putting standard.
A kind of waste and the innoxious minimizing recycling treatment process system of industrial sludge, which is characterized in that including dirt Mud sump, dewatering module, dewatered sludge splicing module, dewatered sludge conveyor module, waste pond, grab bucket mechanism, half gasification burning Oven module, heat exchanger, thermal power station and deodorizing module；The half gasification burning oven module includes half vaporizer, combustion chamber, the Level-one subsiding and purifying room, second level electrostatic depuration room, third level filtration, purification room and blowing system；The deodorizing module includes collection Gas hood, blower fan group, combined duster and biofilter；The sludge-tank is equipped with pumping installations, by the intracorporal sludge pumping in pond Dewatering work is carried out into dewatering module；The dewatered sludge splicing module carries out the undertaking of dehydrated sludge and is delivered to dehydration Feed bin in sludge conveyor module；Dewatered sludge is delivered in half vaporizer by the dewatered sludge conveyor module to be burned； The grab claw structure is built in right above waste pond, and grab bucket mechanism has the ability of front and rear, left and right, lifting moving, and completes It grabs waste material and is discharged to the movement burned in half vaporizer；The heat exchanger is connected to combustion using utilidor Room and thermal power station are burnt, the heat transfer that material in combustion chamber is burnt is into thermal power station；Half incinerator Half vaporizer, combustion chamber, first order subsiding and purifying room in module, second level electrostatic depuration room, third level filtration, purification room bottom Portion is all equipped with waste residue outlet, waste residue carry out it is centralized and unified fill, brickmaking, the processing such as cement；The half gasification burning oven module In half vaporizer there are multiple opposite outer walls cylinder tangent-type feed inlets, and be distributed on half vaporization chamber outer wall, realize charging Uniformly, persistently, the small purpose of fluctuation, such design is when moisture content of material is less than 60%, a small amount of successional feed of multiple spot It can be achieved in addition to needing combustion adjuvant combustion-supporting when burning first time, when normal operation can accomplish that material spontaneous combustion is not required to add combustion adjuvant again (material is influenced moisture content by high temperature preheating in dropping process and is further decreased)；Half vaporizer of the blowing system offer, Combustion chamber, first order subsiding and purifying room, second level electrostatic depuration room, third level filtration, purification room oxygen for combustion, offering oxygen way The centre bottom of each room is connected to using pipeline；The gas gathering mask is used to collect dust, the foul smell that waste and sludge generate, and leads to Blower fan group pumping work is crossed, gas gathering mask internal negative pressure state is formed, dust, foul smell pass through combined duster and biofilter Combination filtering, can low energy consumption reach national emission standard.
The incineration treatment technology system includes the following steps:
1) by sludge by being transported in sludge-tank；
