Technical field
The present invention relates to agriculture and forestry organic waste material recycling and biogas engineering biogas residue and biogas liquid separation technology field and in particular to
A kind of continous way biogas slurry filter and method.
Technical background
Biogas slurry, as the product of the fermentation such as agricultural organic waste, feces of livestock and poultry, domestic organic garbage, price is low
Honest and clean, wide material sources, its internal component is rich in compared with multi-nutrient element, degeneration-resistant, sterilization component and crop growth accelerant, is to grind at present
Study carefully the popular green organic fertilizer of comparison.Because the fermented rear biogas slurry being formed is tasteless, fertilizer efficiency often general chemistry synthesis again
More than 10 times of fertilizer, and water quality characteristic is also easily absorbed by crops, so biogas slurry has in agriculture and forestry organic waste material recycling
The prospect of being widely applied.
But due to often containing more biogas residue, impurity and scum silica frost in biogas slurry, easily block in sprinkling irrigation application
Shower nozzle, leads to spraying effect not good, makes the application of biogas slurry be subject to more serious restricting with promoting.Biogas slurry filters, and is to solve this
One of important method of one problem.Biogas slurry filter common at present, is carried out using sieve method or extruding filtration method mostly
Separation of solid and liquid is realizing the filtration of biogas slurry.Because the biogas residue in biogas slurry and stalk crude fibre are easy to block mesh screen, need the cycle
Property ground stop the work of biogas slurry filtration separation, dismounting cleaning screen pack of offing normal realizing the recycling of screen pack, to ensure biogas slurry
That filters proceeds.Additionally, the biogas residue after biogas slurry filtration, when slagging tap, also tend to need to stop biogas slurry filtration work to enter
Row is slagged tap.These discontinuous biogas slurry filter methods, not only affect persistently carrying out of biogas slurry filtration work, and maintenance of clean-up are not
Just, it is higher that the equipment being related to also tends to complex structure, cost.Seek a kind of structure be simple and convenient to operate, cheap biogas slurry
Filter and method, it appears particularly important.
