When 2, digging pit, as run into the bottom cavity arranged, stone or the part landslide is arranged should in time be handled, in order to avoid cause reinforced load-bearing after-bay body by the stone bursting or burst.
Running into tree root when 3, digging pit must cut off, and coats waste diesel or lime in incision and it is stopped growing so that rot, in case the growth of tree root destroys the pond body.
4, dig back, hole application tape measure and check, so that finishing.
Two, assembling
1, begin to install before, whether the scrutiny assembly has damage, in time repairs or changes if any damaging.
2, instruct down second spheroid 2 of first assembly unit, first spheroid 1 of assembly unit, then assembly unit feed-pipe 3 and extraction line 4, assembly unit bottom 6 at last then the professional and technical personnel.
3, put the pond before, evenly fill out earlier and put thick carefully the loosening the soil of one deck 30-50mm at the end, hole, fill out thick point at the soil that the bottom, pond is divided.When putting the pond, whole spheroid is lowered in the hole by label orientation, sets level, less water and compacting are watered by backfill soil to spheroid 1/3rd places.
4, said removable cover 5 is installed after backfill is accomplished, and is with the cementing agent of specialty that removable cover 5 and main tank body is bonding good, tightens anti-holder bolt again, injects water, should note keeping top movable lid 5 not dewater for a long time here.
5, on removable cover 5 tops, bore a hole, be stained with production well, install opening-closing valve.
6, pneumatic tube is bonding water regulator, devulcanizer to be installed on the pipe valve and pipeline to be introduced indoor, connect biogas apparatus such as kitchen range, light fixture.
Three, pressure testing
1, the sealing plate centre hole is got through, has been welded ventpipe, sealed strip be embedded in sealing plate in the groove, be contained in then on the inspection window of ball.
2, micromanometer is connected on the pipe, the ball internal pressure is risen to 1.5 ten thousand handkerchiefs after, dip in washing powder water with all sealing seam brushes one time with hairbrush, whether inspection has the gas leakage point.
Four, examination fire
When weather gage has demonstrated air pressure, the examination fire of can exitting, biogas fermentation initial start stage; The gas that is produced mainly is the carbonic acid gas that produces through acidification, also have a large amount of air when sealing the pond simultaneously in the methane-generating pit, thereby the methane content in the gas is low; Usually can not burn, so, when the water column on the biogas pressure table reaches 3KPa when above; Should put 1-2 time gas earlier, treat in the pond that the methane content of gas reaches 30% when above, can light use.
More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
