Embodiment 1

[0024] Embodiment 1: A kind of poultry manure processing method, poultry manure is placed in the high-temperature negative-pressure airflow of 500 ℃, and then stirred to pulverize the poultry manure; Separate and discharge from the high-temperature negative-pressure air flow; the time for poultry manure to be kept in the high-temperature negative-pressure air flow should be such that the poultry manure is only heated to 95°C by the high-temperature negative-pressure air flow when discharging; During the process, when the temperature of the poultry manure itself reaches 70°C, the moisture inside the poultry manure can reach the boiling point and evaporate; the odor molecules inside the poultry manure can overflow from the poultry manure under the combined action of stirring and crushing and high-temperature negative pressure airflow Decomposed by pyrolysis.

Embodiment 2

[0025] Embodiment 2: A kind of poultry manure processing method, poultry manure is placed in the high-temperature negative-pressure airflow of 650 ℃, and then stirred to pulverize the poultry manure; Separate and discharge from the high-temperature negative-pressure air flow; the time for poultry manure to be kept in the high-temperature negative-pressure air flow should be such that the poultry manure is only heated to 105°C by the high-temperature negative-pressure air flow when discharging; During the process, when the temperature of the poultry manure itself reaches 80°C, the moisture inside the poultry manure can reach the boiling point and evaporate; so that the odor molecules inside the poultry manure can overflow from the poultry manure under the combined action of stirring and crushing and high-temperature negative pressure air flow. Decomposed by pyrolysis.

Embodiment 3

[0026] Embodiment 3: A kind of poultry manure processing method, poultry manure is placed in the high-temperature negative-pressure airflow of 600 ℃, and then stirred to pulverize the poultry manure; Separate and discharge from the high-temperature negative-pressure air flow; the time for poultry manure to be kept in the high-temperature negative-pressure air flow should be such that the poultry manure is only heated to 100°C by the high-temperature negative-pressure air flow when it is discharged; During the process, when the temperature of the poultry manure itself reaches 75°C, the moisture inside the poultry manure can reach the boiling point and evaporate; the odor molecules inside the poultry manure can overflow from the poultry manure under the combined action of stirring and crushing and high-temperature negative pressure air flow. Decomposed by pyrolysis.

Abstract

The invention discloses a treatment method of poultry manure, which is characterized by comprising the following steps: placing the poultry manure in high-temperature and negative-pressure air flow at 500-650 DEG C, then stirring and crushing the poultry manure; maintaining the poultry manure in the high-temperature and negative-pressure air flow for some time to ensure that the discharged poultry manure is only heated to 95-105 DEG C by the high-temperature and negative-pressure air flow, then separating out and discharging the poultry manure from the high-temperature and negative-pressure air flow; and controlling negative-pressure of the air flow so that moisture in the poultry manure evaporates after reaching a boiling point while the poultry manure reaches the temperature of 70-80 DEG C during the process of crushing the poultry manure and odor molecules in the poultry manure are overflowed from the poultry manure and subject to high-temperature decomposition under the combined action of stirring and pulverizing and the high-temperature and negative-pressure air flow. The treatment method of the invention has the characteristics of high drying efficiency, good deodorization effect, no odor pollution, low bacterial content but high nutritional value of the treated poultry manure.

Description

technical field [0001] The invention relates to a pre-processing method for using poultry manure to manufacture feed. [0002] Background technique [0003] All large-scale mechanized poultry farms will face a more important problem, namely how to deal with poultry manure. According to statistics, a poultry discharges about 100 grams of wet poultry manure on average every day, and a mechanized poultry farm that raises 300,000 poultry can discharge up to 30 tons of wet poultry manure every day. A large amount of wet poultry manure not only provides a breeding ground for the growth of pathogenic bacteria and maggots, but also the stench emitted can reduce the egg production rate of poultry. Traditional poultry manure treatment is generally used for fertilizer, its utilization rate is relatively low, and poultry farmers are not interested, so many poultry farms will cause poultry manure to accumulate, and its odor, waste water, etc. will cause serious environmental pollution ...
