Abstract

A device to generate biogas. It mainly to resolve the existing problems, such as complexity of construction of methane pool, high cost and inconvenience of removing slag. The main points of the technical scheme of the device includes that the device consists of a pool, a feed inlet, a feed- inlet pipe that is connected with the bottom of the pool and the bottom of the feed inlet respectively, a feed-out pool and a feed-out pipe that is connected with the bottom of the pool and the bottom of the feed-out pool respectively. The pool is a cylinder with an open upper and a closed bottom. A gas-collecting hood with a closed upper and open bottom matches the inner wall of the pool, a gas pipe that is arranged on the upper of the hood is connected with the inner chamber of the gas-collecting hood. The feed inlet is higher than the feed outlet and the pool is higher than the feed-out pool. The device is mainly used to generate biogas that can be used as energy by fermenting human and brutes' feces, plants' leaves and stalks, other by-products of agriculture and weeds. The biogas generating device can resolve the problems of energy and environment in the countryside, and increase agricultural comprehensive benefits.

Description

Biogas generating device

Affiliated technical field

The utility model relates to a kind of biogas generating device.

Background technology

At present, existing methane-generating pit all is to adopt the closed one-piece construction, and difficulty of construction is relatively large, and cost is just higher relatively at peasant's income, and the inconvenience of slagging tap greatly.

Summary of the invention

The purpose of this utility model provides a kind of easy construction, lower-cost biogas generating device.

The technical scheme that its technical problem that solves the utility model adopts is: it comprises pond body 7, opening for feed 1, the feed-pipe 2 that communicates with pond body 7 bottoms and opening for feed 1 bottom respectively, material-output tank 5, the discharge nozzle 6 that communicates with pond body 7 bottoms and material-output tank 5 walls middle part respectively, it is characterized in that: pond body 7 is the cylinder of the uncovered lower end closed in upper end, be provided with the tracheae 4 that communicates with the gas skirt inner chamber with open cylinder gas skirt 3 tops, upper end closed lower end that body 7 inwalls in pond match, the upper height of opening for feed 1 is greater than the upper height of pond body 7, and the opening end height of pond body 7 is greater than the uncovered height of material-output tank.The external diameter of gas skirt 3 is less than or equal to pond body 7 internal diameters, and the closure tip of gas skirt 3 is plane or cambered surface, passes the gas skirt wall with tracheae 4 that burner joins and communicates with the gas skirt inner chamber.The top of gas skirt 3 is provided with weight.Can cross filtering barrier 8 by suit on the inwall of pond body 7, the external diameter of the gas skirt 3 that matches with mistake filtering barrier 8 was less than or equal to the internal diameter of filtering barrier 8.

The beneficial effects of the utility model are, easy construction is slagged tap conveniently, and cost is relatively low, can reduce cost 20% to 40% according to preresearch estimates.It mainly is to be used for fermentations such as subsidiary product of farm crop such as the leaf of human and animal excreta such as people, pig, ox and plant, bar and weeds are formed methane; use as the energy for people; and then play rural energy, protection environmental problem, the effect that improves overall efficiency of agriculture of solving.

Embodiment

Embodiment 1, as shown in Figure 1, the utility model comprises pond body 7, opening for feed 1, the feed-pipe 2 that communicates with pond body 7 bottoms and opening for feed 1 bottom respectively, material-output tank 5, the discharge nozzle 6 that communicates with pond body 7 bottoms and material-output tank 5 bottoms respectively, pond body 7 is the cylinder of the uncovered lower end closed in upper end, the upper height of opening for feed 1 is greater than the upper height of pond body 7, by utilizing the gravity of the discrepancy in elevation and object self, raw material is entered the pond body 7 smoothly from opening for feed 1, because of the opening end height of pond body 7 greater than the uncovered height of material-output tank, waste material after the fermentation then can not overflow from the suitable for reading of pond body 7, and can flow into material-output tank 5, thereby realize advancing automatically raw material and waste discharge material by discharge nozzle 6.Be provided with the tracheae 4 that communicates with the gas skirt inner chamber with open cylinder gas skirt 3 tops, upper end closed lower end that body 7 inwalls in pond match, the external diameter of gas skirt 3 is slightly smaller than or equals pond body 7 internal diameters, the closure tip of gas skirt 3 can become plane or cambered surface or hemisphere face, passing the gas skirt wall with tracheae 4 that burner joins communicates with the gas skirt inner chamber, gas skirt 3 is under the self gravitation effect, the lower port of gas skirt 3 is submerged in the stock liquid of pond body 7 inner chambers, thereby between the inwall of gas skirt 3 and pond body 7, form water seal, the biogas that produces in the pond body 7 can not leak, but rise to naturally in the inner chamber of gas skirt 3 on top, because of the weight of gas skirt 3 certain, gas in gas skirt increases, when pressure increases, promote then that gas skirt 3 moves upward and the gas space that enlarges the gas skirt inner chamber; Otherwise, gas in gas skirt reduces, when pressure reduces, then gas skirt is under the effect of self gravitation, gas skirt is moved downward make the gas skirt bottom deeper to be inserted in the stock liquid of pond body 7 and the gas space of gas skirt inner chamber is dwindled, relatively stable with the pressure in the maintenance gas skirt, thereby the gaseous tension that burner is obtained is relatively stable, firepower is also stable.

Embodiment 2, and as shown in Figure 2, the utility model can be set up a mistake filtering barrier 8 on the inwall of pond body 7, and the external diameter of the gas skirt 3 that matches with mistake filtering barrier 8 was less than or equal to the internal diameter of filtering barrier 8.Cross filtering barrier 8 and play the effect that the inabundant pond liquid that ferments is not outflowed, all the other are with embodiment 1.

Embodiment 3, in order to increase the air pressure in the gas skirt, promptly increase the pressure of burner using gas, set up a weight at the top of gas skirt 3, thereby increased the downward pressure of gas skirt, and the biogas pressure that tracheae 4 is discharged increases.All the other are with enforcement 1 or embodiment 2.
