Description

Computer is controlled automatic methane-generating pit

One, technical field

The utility model relates to a kind of methane-generating pit, and especially a kind of charging and discharging automatically and the computer that stirs are automatically controlled automatic methane-generating pit.

Two, background technology

Biogas is used by vast rural area just more and more widely, for the fuel problem that solves the peasant, does rural environmental hygiene well, fully develops the renewable energy resources and plays crucial effect.But there are a lot of technological deficiencies in existing methane pool: 1, for example biomass pool built from glass fiber reinforced plastic, because the pond type is unreasonable, and can not annual aerogenesis, water pressure house is too little, takes place excessively to rainy season, the many families of the family expenses gas phenomenon of being injured occurs; Floor space was too big when 2, methane-generating pit was installed, and what have builds a 8m ³Methane-generating pit need 17.2m ²Area.Even so, the water pressure house that has is too little even do not have water pressure house, let alone between liquid storage; 3, it is single to require to produce the biogas raw material, only limits to end user, animal manure just, can not use stalk; 4, use is loaded down with trivial details, what requires will stir after an action of the bowels down, is unfavorable for that the peasant grasps; 5, have three difficult problems, i.e. charging difficulty, stir difficult, discharging is difficult; 6, complex structure, charging and discharging pipe oblique cutting has not only increased materials and recruitment outside methane-generating pit, and the vibrations of the earth's crust can make the junction of charging and discharging pipe that seepage takes place; 7, cost is expensive.

Three, summary of the invention

At the deficiencies in the prior art, the utility model provide a kind of design science, rational in infrastructure, make to install easily, cost is lower, level of automation is high, and floor space is little, produce the variation of biogas raw material, the computer that is beneficial to grasp, long service life is controlled automatic methane-generating pit.

A kind of by fermentation vat, feed-pipe, communicating pipe, pneumatic tube, catch basin, water pressure house, in advance macerate between and the computer formed between liquid storage control automatic methane-generating pit, also comprise mateiral pump and computer, water pressure house, in advance macerate between and merge into three ponds between liquid storage, these three ponds are positioned at above methane-generating pit, the fermentation vat and with discharge nozzle and feed-pipe and are communicated with, feed-pipe that is communicated with fermentation vat and discharge nozzle are installed in the methane-generating pit, and mateiral pump and communicating pipe, feed-pipe and three ponds are connected and are electrically connected with computer.

Described feed-pipe is made up of coarse filtration pipe and fine filtering pipe box dress, and outer tube wall is provided with the coarse filtration hole, and inner pipe wall is provided with the fine filtering hole.

Described three ponds are provided with the liquid pumping hole that is used for toilet flushing and pigsty.

During use, be installed on apart from ground methane-generating pit below 3 meters.2.5 the ground temperature that rice is following, ground temperature can remain on 17 ℃ summer, can remain on 15 ℃ winter; Because have three ponds, waterborne of pond to have methane tank cover and soil layer to cover again above the fermentation vat, waterborne of pond also has air heat-insulation layer, the temperature fermentation vat pond temperature when summer temperature is 39 ℃ in the fermentation vat still remains on 23 ℃; Can keep 18 ℃ season three nine-day periods after the winter solstice in the winter time, the temperature peak of therefore having pruned, fill and lead up the temperature low ebb, not only realize long-term air feed problem, and solve have more than is needed, the problem that winter the is not enough and problem that wastes raw material summer in biogas summer.

Because the biomass pool structure compactness, the charging and discharging pipe all is installed in the methane-generating pit, has not only reduced cost, and has reduced floor space, a methane-generating pit is installed is taken up an area of 9.18m than existing methane-generating pit saving ², also saved manufacturing methane-generating pit materials; Simultaneously also solve existing methane-generating pit charging and discharging pipe coupling place and leakage problems occurred.

The design in three ponds has enlarged the space of original water pressure house, plays between liquid storage again and the effect between macerating in advance simultaneously.During use, raw material is thrown in three ponds, when making full use of three the natural pond liquid pond in and rise, the time and the characteristics that descend are macerated raw material in advance and to be made, and saved when macerating the pond in advance with special use, need the process of special extraction natural pond liquid; Simultaneously, when macerating raw material in advance, in order to regulate carbon-nitrogen ratio, add urea or bicarbonate of ammonia, solved raw material after the ammoniumization and produced ammonium gas methanobacteria is produced disadvantageous problem, also can decompose the part repressor, reached fermentation vat and normally move, removed from special use and macerated the heavy manual work in pond in advance, improved pretreating effect.

Because drawing liquid at any time around three ponds, but equal liquid-pumping flush lavatory or pigsty on any one direction, not only solved in the other problem of building lavatory and pigsty of methane-generating pit, and no longer used flushing with clean water lavatory and pigsty, prevented that clear water from entering fermentation vat to the disadvantageous problem of methanobacteria.Because opening for feed is arranged on the side, has overcome rainwater and has entered the disadvantage that fermentation vat waters down natural pond liquid or fermentation vat is filled.

Owing to used computer control, power feed, mechanical discharging and mechanical stirring have been realized, under computer control, regularly stirring, automatic feed and discharging on time, solve the three difficult problems that existing methane-generating pit exists, greatly reduced labour intensity, improved user's sanitary condition.

The utlity model has design science, rational in infrastructure, make to install easily, cost is lower, level of automation is high, and floor space is little, produce the variation of biogas raw material, be beneficial to the characteristics of grasp, long service life.
