Cow dung incineration treatment and reuse process for cattle farms

Abstract

A cow dung treatment system comprises a batching pool, a solid-liquid separation device, a dung drying shed, a dung dryer, a fluidized bed incinerator, a waste heat boiler, a cyclone dust collector, a heat exchanger, a spray washing tower, a sand-lime separator, a sand storage hopper, a lime storage hopper, an air compressor, an activated carbon feeder, an activated carbon storage bin, a bag-type dust collector, an activated carbon regeneration bin, a chimney, a residue storage pool, a slaked lime storage bin, a slaked lime dissolving tank, a lime slurry tank, a cooler, a rubbish storage tank, an oil drum, a wastewater pool and the like. According to the cow dung treatment system, the cow dung treatment efficiency is greatly improved, the cow dung treatment rate can reach 100%, and the capacity reduction rate can reach 98%; in addition, the technology is reasonable, the structure is compact, contaminants can be reduced, the surrounding environment can be improved, and meanwhile resources are reasonably used to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of environmental governance and resource utilization, in particular to a cow dung incineration treatment and recycling process for cattle farms. Background technique [0002] In recent years, the cattle breeding industry has developed rapidly. With the increasing scale of breeding, the accompanying manure problem has seriously affected its own sustainable development. According to the measurement, the cow dung produced by a cow every day is 5% to 6% of its body weight, that is, a 450kg cow can excrete about 25kg of manure every day on average, so there are as many as 9000kg a year. Therefore, the amount of cow dung that a cattle farm with a certain scale produces in a year is then very huge. Cow dung stacked in the open air produces a large amount of greenhouse gas methane, which not only seriously restricts the sustainable development of the cattle industry, but also has a major impact on climate change; r...
