Biogas slurry pipeline fertilizing device

Abstract

The invention relates to a biogas liquid pipeline fertilization device, which includes waste water disposal pump placed at the bottom part of the biogas liquid storage pool, the inverted valve which is placed above the immersed type waste water disposal pump, the liquid inlet tube which is connected to the inverted valve, the main tube which is connected to the liquid inlet tube, the fast pressure-relief valve and gate valve which are installed on the main tube, many branch tubes which are connected to the main tube, the water outlet pile which is connected to the main tube or the branch tube, the control valve which is fixed on the said water outlet pile, the soft tube which is connected to the water outlet pile, the deposit collecting tubes which are installed at the bottom part and the right angle corner of the main tube and branch tubes, the outlet valve which are installed on the said main tube and the branch tubes. The biogas liquid pipeline fertilization device can fertilize the field, which is good for environmental protection, and has the advantages of low cost and long lifespan.

Description

technical field [0001] The invention relates to a pipeline fertilization device for biogas slurry, in particular to a pipeline fertilization device for returning breeding manure to the field. Background technique [0002] Large-scale farming will produce a large amount of manure, which has a negative impact on the environment, and has caused harm to the rural environment, drinking water sources and agricultural ecology. Because manure contains a large amount of short fibers, it is difficult to transport through pipelines. It is mainly picked up and applied by human and animal power. The traditional method of use is high in cost, complicated in use, and low in efficiency. It is difficult to digest the manure produced by large-scale farming. High-quality organic fertilizers often It can only be discarded and cause environmental pollution. On the other hand, the planting industry must use a large amount of chemical fertilizers, making it the largest source of rural non-point s...

AI Technical Summary

Problems solved by technology

Some enterprises adopt dry and thin separation, which only reduces the discharge of excrement and sewage, but cannot fundamentally solve the problem of environmental pollution caused by excrement discharge. Moreover, open-air fermentation of dry excrement, land occupation problems, odor, mosquitoes and flies pollute the environment, feces Problems such as excessive heavy metal pollution in China are difficult to solve

Some enterprises use ordinary irrigation pipes after biogasification of farm manure, but because the biogas slurry contains a lot of chemical substances that will corrode the pipes, ordinary water pumps are easy to block, and the secondary fermentation of the biogas slurry in the pipeline will cause the pipe to burst. Impurities such as biogas residues and microorganisms will also cause corrosion and blockage through the pipeline, so it is difficult to effectively use the biogas slurry

All use mobile irrigation hoses, which are not suitable for large and medium-sized breeding farms, and the hoses have a limited service life and are prone to damage and leakage. Excessive leakage will lead to deterioration of the working environment, and residual liquid pollution in the pipeline will affect pipeline collection.

[0003] At present, there is no system device for returning farm manure to the field
