The utility model content
The utility model is for the defective of prior art, provide a kind of floor space little, simple in structure, build the lower-cost revolving-flow methane-generating pit in pond.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of revolving-flow methane-generating pit, comprise biomass pool body, the middle part, top of biomass pool body is provided with upper outlet, be provided with the feed-pipe and the discharge nozzle that insert biomass pool body inside on the described biomass pool body, feed-pipe and discharge nozzle are positioned at the same side of biomass pool body, feed-pipe and discharge nozzle are precast concrete pipe, and biomass pool body is inner, be provided with the revolving-flow wall between feed-pipe and discharge nozzle, and a side of this revolving-flow wall links to each other with the biomass pool body inwall.This device has been cancelled the feed-pipe of tapping channel and oblique cutting placement, all adopts precast concrete between charging and discharging pipe and charging and discharging.
As preferably, at the bottom of the pond 35 centimetres and 55 centimetres respectively of described feed-pipe, discharge nozzle bottom surfaces.
As preferably, described biomass pool body outer wall is equipped with thermal insulation layer.
As preferably, described feed-pipe and discharge nozzle suitable for reading is positioned at the biomass pool body outside in being arranged between control between control, and fixes with the outside wall surface of biomass pool body, is rectangle between control.
As preferably, the diameter of described feed-pipe and discharge nozzle is 30 centimetres.
The beneficial effects of the utility model are: (1) floor space is little, is more suitable for most of Rural Yard and builds the pond requirement, and water pressure house is built on this device vault, has reduced floor space, and thing takes up an area 3.2 meters, is no more than a room and takes up an area, and the masses are acceptant.
(2) it is simple to build pool technology, has reduced difficulty of construction.Replace having reduced difficulty of construction between tapping channel and input and output material with 30 centimetres of prefabricated pipe of diameter.
(3) prefabricated pipe with 30 centimetres of diameters replaces between input and output material, and the space is less, and methane-generating pit initial start pressure rise is very fast, is conducive to methane-generating pit igniting gas testing.
(4) charging and discharging pipe bottom surface is at the bottom of the pond 35 centimetres and 55 centimetres respectively, and under the effect of biogas power, the sedimentary fermentation feed liquid flows into acidification pool by discharge port, realizes automatic stirring, and forces the efficient running status such as one-way circulation.Prevented that simultaneously sediment from appearring in biogas.
(5) it is low to build the pond cost.A bite methane-generating pit can lack earth excavation 2.75m after improving
3, save concrete 0.4m
3, save 2 of man-hours, every mouthful of methane-generating pit can be economized on the use of funds 500 yuan.
