Among the figure: 1, fermentation vat, 2, the gas storage pond, 3, waste tank, 4, the air outlet, 5, feed opening, 6, tremie pipe, 7, arched door, 8, slug hole, 9, discharge gate.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done description in further detail, technical scheme of the present invention is not limited to following examples:
As shown in Figure 1; Biogas pool for rural residents of the present invention comprises columniform fermentation vat 1, hemispheric gas storage pond 2 and rectangular waste tank 3, and a side and the waste tank 3 of fermentation vat 1 join, and gas storage pond 2 is positioned at the top of fermentation vat 1 and communicates with fermentation vat 1; It is characterized in that; In the joint of described fermentation vat 1 with waste tank 3, be provided with an arched door 7, the central position of arched door 7 is provided with a slug hole 8; The central position at 2 tops, gas storage pond is provided with an air outlet 4, and the middle part of gas storage pond 2 one sides is provided with a feed opening 5, and the top of waste tank 3 one sides is provided with a discharge gate 9.
The method of manufacture of above-mentioned biogas pool for rural residents comprises the steps:
1) according to user's requirement, select the construction site of methane-generating pit, for example, in the pigsty, in the cowshed, in the green house of vegetables, before the room or wait behind the house;
2) utilize digging tool to excavate methane-generating pit in construction site, the volume in pond and the degree of depth depend on makes the raw materials used amount of biogas, the total depth H in pond 1Generally about 1.8-2m, the depth H of fermentation vat 1 0Generally about 1m, meet national 8m 3The methane-generating pit standard in the bottom surface of methane-generating pit, is paved with the C20 concrete manual work that 8cm is thick, and the home position of confirming cylindrical fermentation vat 1 according to the volume and the degree of depth of the required fermentation vat 1 of user;
3) build out 39-40cm cylindrical fermentation vat 1 and rectangular waste tank 3 highly with No. 25 common bricks and No. 50 mortars; In joint, two ponds; Build an arch door opening apart from fermentation vat bottom surface 57-58cm height, the discharging channel when being used for the workmen and passing in and out passage and the secondary material feeding of fermentation vat 1, then; Two ponds are upwards built out high fermentation vat of 1m 1 and the high waste tank 3 of 2m respectively along arch door opening top, the volume of waste tank 3 is as the criterion can let a workmen freely come in and go out; In this process, build out a discharge gate 9 that diameter is about 2 cun, be higher than h in the side that about 1.5m of waste tank 3 highly locates 3The waste material of=1.5m can directly enter green house of vegetables etc. from discharge gate 9, and to need waste material be the place of green fertilizer, and the waste material that residue stores can make things convenient for the user to use at any time;
4) first at the top of fermentation vat 1 with brick one-tenth semisphere; Use the thick C20 concrete placement of 4cm again; The floating hemispheric gas storage pond 2 of building out of No. 150 mortars that external application 2cm is thick, gas storage pond 2 and the total height of fermentation vat 1 and the level of waste tank 3, promptly 2m is high; In the 2 distance from top centermost 15cm scopes of gas storage pond, build out one three air outlet 4 of being in charge of size; Build out the feed opening 5 about 8 cun at the middle part of gas storage pond 2 one sides, and make feed opening 5 center, arch door opening center and discharge gate 9 the projection of center on the methane-generating pit bottom surface point-blank so that raw material can fully react in fermentation vat and can redundant moisture or waste liquid be discharged from waste tank at any time; Then, the anticorrosive adhesive coating is all used in the fermentation vat 1 and the inside in gas storage pond 2;
5) after fermentation vat 1 finishes building with gas storage pond 2; Workmen in the fermentation vat 1 gets in the waste tank 3 from the arch door opening; With arched door 7 sealings, arched door 7 can be wooden sealing plate or rubber gasket sheet or thermal-insulating sealing plate, then with the arch door opening; Open the slug hole 8 of an about 3-5cm of diameter at the center of arched door 7, redundant moisture or waste liquid can enter in the waste tank 3 from slug hole 8 in the fermentation vat;
6) the anticorrosive adhesive coating is used in the inside of waste tank 3, the workmen is come out by waste tank 3, and is last with the top seal of concrete prefabricated board with waste tank 3, and the outside of methane-generating pit is filled and led up with soil.Because of the difference of methane-generating pit manufacturing location, such as before and after the house, the top of waste tank 3 can be above the ground level, and promptly exceeds the top in gas storage pond 2, in order to avoid the water on ground flows into methane-generating pit, influences the output of biogas.
Methane-generating pit of the present invention in use, tremie pipe 6 inserts from feed opening 5, its depth of penetration can be confirmed according to the raw material quantity of required input, still, guarantee the height h of the bottom surface of tremie pipe 6 apart from fermentation vat 1 bottom surface 1Greater than the height h of slug hole 8 apart from fermentation vat 1 bottom surface 2About 5cm.
