Production process of chicken manure ash used for fertilizer additive

Abstract

The invention relates to the technical field of breeding waste reprocessing, and discloses a production process of chicken manure ash used as a fertilizer additive. The rice dung husk is further transported to the chicken manure boiler for combustion treatment, and the heat generated by the combustion is transported to the downstream power plant for power generation; the chicken manure ash obtained after complete combustion is pumped into the flue gas purifier for gravity separation, The chicken manure ash in the lower layer falls into the ash tank and is pumped to the chicken manure ash storage warehouse, and the upper layer flue gas is discharged from the chimney through the induced draft fan; the chicken manure ash is sampled for element determination; according to the element determination results, the chicken manure ash is added to the Fertilizer and mix well in the mixing tank. The invention carries out environmental protection and ecological treatment on the breeding waste, fully utilizes the resources, uses the heat generated by combustion to generate electricity, and the chicken manure ash produced is used as a phosphorus or potassium additive in potash and phosphate fertilizers.

Description

technical field [0001] The invention relates to the technical field of breeding waste reprocessing, in particular to a production process of chicken manure ash used as a fertilizer additive. Background technique [0002] With the development of domestic white-feather chicken breeding industry, a large amount of waste such as "chicken manure + rice husk" mixture will be produced every day in the process of white-feather chicken breeding. Traditional disposal methods such as land stacking will inevitably have a certain impact on the environment, and the bacteria produced in the waste will also pose a threat to sanitation and health; on the other hand, the mixture of "chicken manure + rice husk" is also a kind of Use valuable resources. Therefore, how to carry out batch and large-scale processing to turn waste into treasure has become increasingly important. In the process of processing the mixture of "chicken manure + rice husk", about 10% chicken manure ash will be produced...
