Harmless treatment equipment and method for treating livestock and poultry manure through same

Abstract

The invention discloses harmless treatment equipment. The harmless treatment equipment comprises a roller device, a heat-conducting oil furnace heating device and a condensing deodorization device; the roller device comprises a feeding pool, a spiral feeding conveyor, a roller body and a speed reduction motor for driving the roller body to rotate; flange plates are arranged at openings of the tipsof the two ends of the roller body correspondingly, and a plurality of sealed rubber sealing rings making contact with the outer side walls of the flange plates are fixed to the inner side wall of aconnecting end cover; the heat-conducting oil furnace heating device comprises a furnace body, a fire inlet hole, an air outlet hole, a top heat-conducting oil pipeline, a bottom heat-conducting oil pipeline and a heat source channel; and the condensing deodorization device comprises a bottom frame, a primary spraying tower, a condensing device, a secondary spraying tower and a high-pressure ionization device, the primary spraying tower is mounted on the position, close to the front and right parts, of the top of the bottom frame, and the secondary spraying tower and the high-pressure ionization device are mounted on the positions, close to the front and left parts of the bottom frame, of the left side of the primary spraying tower. According to the harmless treatment equipment, the problem that an aerobic fermentation technology is large in odor is solved, and the problems that the aerobic fermentation cycle is long, and the occupied area is large are further solved.

Description

technical field [0001] The invention relates to the technical field of harmless treatment, in particular to a harmless treatment device and a method for treating livestock and poultry manure. Background technique [0002] At present, the harmless treatment mainly includes landfill treatment, incineration treatment and composting treatment. The landfill treatment method is the most common garbage treatment method. Its biggest feature is that the treatment cost is low and the method is simple, but it is easy to cause secondary pollution of groundwater resources. With the increase in the amount of urban garbage, suitable landfills near cities There are fewer and fewer burial sites, and the development of long-distance landfill sites has greatly increased the cost of waste discharge. Such high costs are even unaffordable, and it is not a cure for the symptoms; [0003] The advantage of incineration treatment is that it has a good reduction effect (the volume of the residue afte...

AI Technical Summary

Problems solved by technology

The use of a straight-through inner cavity will greatly shorten the path of the heat source passing through the furnace body cavity, reduce the contact time with the heat conduction pipe, and the utilization rate of the heat source is low. Generally, the length or height of the furnace body is increased to increase the utilization rate of the heat source, resulting in equipment failure. Large volume, not suitable for high-intensity heat source output

[0007] Existing harmless treatment equipment generally absorbs and filters odors from odor-polluted gases after high-temperature fermentation through single-function deodorization equipment. This type of existing equipment still has some technical defects in use, such as: this type of deodorization equipment does not have Cooling function, high-temperature gas has low density, high humidity, and low specific gravity of odorous gas. On the one hand, water will greatly dilute the deodorizing material, increase the cost of deodorization, and also lead to unsustainable work and low stability. Poor; on the other hand, high-temperature gas will increase the temperature of deodorizing materials after entering the deodorizing equipment, which will lead to a decrease in deodorizing performance
