The incineration treatment has the advantages of good decrement effect (the volume of the residue after incineration is reduced by more than 90 percent, the weight is reduced by more than 80 percent), thorough treatment, but in most cases, the electric energy value generated by the equipment is far lower than the expected sales volume, huge economic loss is left for local governments, and the incineration has high toxicity and secondary environmental hazard because the garbage contains certain metals;
The domestic garbage is piled up into piles, stored and fermented at the temperature of 70 ℃, organic matters are decomposed into inorganic nutrients by means of the capability of microbial decomposition in the garbage, and the domestic garbage is changed into sanitary and tasteless humus after composting treatment, so that the purpose of recycling is achieved, but the domestic garbage is large in compost quantity and low in nutrient content, soil hardening and underground water quality deterioration are easily caused after long-term use, the compost scale is not easy to be too large, and the problems can be solved by adopting harmless treatment equipment.
The existing innocent treatment equipment is generally of a horizontal roller structure, two ends of a roller are both sealed end enclosure structures which synchronously rotate, and the existing roller structure realizes the supply and discharge of materials by the positive and negative rotation principle and can not continuously work; in order to change the state of the art, the market has developed a device with a large stock, typically 20-40 meters, which still has some technical drawbacks, such as: the discharging time is long, so that the method is not suitable for the use requirement of a large breeding plant and the requirement of continuous treatment of large sludge amount.
the heat conduction oil furnace that current innocent treatment equipment adopted generally is horizontal or vertical barrel structure, and the inner chamber of this kind of heat conduction oil furnace is the structure of integrative through, is equipped with heat conduction pipeline in this through inner chamber, and this pipeline is mostly helical structure. The path of the heat source passing through the inner cavity of the furnace body can be greatly shortened by adopting the straight-through inner cavity, the contact time with a heat conduction pipeline is reduced, the utilization rate of the heat source is low, the utilization rate of the heat source is generally improved by lengthening or increasing the length or height of the furnace body, the size of equipment is large, and the equipment is not suitable for outputting the high-strength heat source.
The peculiar smell pollution gas after the existing harmless treatment equipment is fermented at high temperature is generally absorbed and filtered by deodorization equipment with single function, and the existing equipment has some technical defects in use, such as: the deodorization equipment has no cooling function, the high-temperature gas has small density, large humidity and small specific gravity of the peculiar smell gas, on one hand, the moisture can greatly dilute the deodorization material, the deodorization cost is increased, the sustainable work can not be caused, and the stability is poor; on the other hand, the high-temperature gas increases the temperature of the deodorizing material after passing through the deodorizing means, resulting in a decrease in deodorizing performance.
In conclusion, the harmless treatment equipment which can be continuously used, is efficient and energy-saving and has thorough tail gas treatment and the method for treating the livestock and poultry manure are imperative.
