Abstract
The utility model discloses a biogas digester with a sealed feeding pipe. The biogas digester with the sealed feeding pipe comprises a digester body and a water pressure chamber, wherein the digester body is provided with an inner cavity, the water pressure chamber is arranged adjacent to the digester body, a gas storage chamber is arranged on the upper portion of the inner cavity of the digester body, a fermentation chamber is arranged on the lower portion of the inner cavity of the digester body, a feeding channel, a discharging outlet and a gas guiding pipe are arranged on the digester body, the feeding pipe which is connected with the feeding channel in a sealed mode is arranged in the feeding channel, a circular-truncated-cone-shaped big-end-down sealing cover is arranged on a feeding inlet of the feeding pipe, and an annular groove which surrounds the feeding pipe for a circle is formed in the position, close to the feeding inlet, of the feeding pipe. Due to the fact that the feeding pipe is connected with the feeding channel in the sealed mode, the gas tightness of the position of connection between the feeding pipe and the feeding channel is improved; due to the fact that a sealing device is arranged on the feeding inlet, leakproofness of the feeding inlet can be better. In addition, due to the fact that the portion, arranged inside the digester body, of the feeding pipe is arranged below the liquid level of feed liquid in the fermentation chamber, biogas raw materials which are input can enter the bottom of biogas slurry, the biogas raw materials can be sufficiently fermented, and the gas production rate is increased.
Description
Technical field
The utility model relates to a kind of methane-generating pit, particularly a kind of methane-generating pit with sealing feed-pipe.
Background technology
Biogas is that organic substance is in anaerobic environment, lower to microorganism fermentative action in certain temperature (more than 10 ℃), concentration (6%) and potential of hydrogen (pH value 6-7), a kind of inflammable gas producing, for preventing that biogas from leaking, cause the poisoning and environmental disruption of personnel, methane-generating pit needs complete hermetic seal.The feed-pipe of general methane-generating pit is in the junction poor sealing with pond body, and more than can being placed on natural pond liquid liquid level, can make like this to expect that slag stays liquid level, easy crust, and ferment effect is bad.
In sum, be necessary to design a kind of methane-generating pit, resistance to air loss be set better, the better feed-pipe of ferment effect, to address the above problem.
Utility model content
In view of this, be necessary to design a kind of methane-generating pit with sealing feed-pipe, resistance to air loss be set better, the better feed-pipe of ferment effect, to address the above problem.
The utility model solves the problems of the technologies described above by following technique means:
The methane-generating pit of band sealing feed-pipe of the present utility model, comprise with the pond body of inner chamber and the water pressure house adjacent with pond body, intracoelomic cavity top, described pond is gas dome, the inner chamber bottom of pond body is proving room, described pond body is provided with feeding-passage, discharge port and airway, and the feed-pipe being tightly connected with feeding-passage is set in described stand in channel.
Further, the opening for feed place of described feed-pipe arranges a up-small and down-big truncated cone-shaped sealing cover, on feed-pipe, near opening for feed position, arranges around the annular ditch groove of feed-pipe one circle.
Further, described feed-pipe enters below the feed liquid liquid level of pool part in proving room.
Further, described feed-pipe is cement pipe or vitrified pipe.
Further, on described sealing cover, a draw ring is set.
The beneficial effects of the utility model: the methane-generating pit of band sealing feed-pipe of the present utility model, comprise with the pond body of inner chamber and the water pressure house adjacent with pond body, intracoelomic cavity top, described pond is gas dome, the inner chamber bottom of pond body is proving room, described pond body is provided with feeding-passage, discharge port and airway, and the feed-pipe being tightly connected with feeding-passage is set in described stand in channel.The opening for feed place of described feed-pipe arranges a up-small and down-big truncated cone-shaped sealing cover, on feed-pipe, near opening for feed position, arranges around the annular ditch groove of feed-pipe one circle.Described feed-pipe and feeding-passage are tightly connected, and resistance to air loss is herein strengthened; Opening for feed place arranges a tightness system, makes the better tightness of opening for feed.In addition, described feed-pipe enters below the feed liquid liquid level of pool part in proving room, and the marsh gas raw materials of throwing in like this can enter liquid bottom, natural pond, can make it ferment comparatively fully, improves gas production rate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below with reference to accompanying drawing, the utility model is elaborated, as shown in Figure 1:
The methane-generating pit of band sealing feed-pipe of the present utility model, comprise with the pond body 1 of inner chamber and the water pressure house 2 adjacent with pond body, intracoelomic cavity top, described pond is gas dome, the inner chamber bottom of pond body is proving room, described pond body is provided with feeding-passage 3, discharge port 4 and airway 5, the feed-pipe 31 that the interior setting of described stand in channel 3 and feeding-passage are tightly connected.Feed-pipe is set to be tightly connected with feeding-passage, makes feed-pipe resistance to air loss when stretching into methane-generating pit better, is difficult for gas leakage.
As the further improvement of technique scheme, the opening for feed place of described feed-pipe 31 arranges a up-small and down-big truncated cone-shaped sealing cover 32, on feed-pipe, near opening for feed position, arranges around the annular ditch groove 33 of feed-pipe one circle.After sealing cover is placed on opening for feed, in annular ditch groove, pour a small amount of water into, the lower edge of sealing cover is immersed in the water.Open sealing cover, can feed intake; Cover after sealing cover, under sealing cover, along being immersed in the water, can block entering of outside air.Such closing device makes opening for feed place better tightness.
As the further improvement of technique scheme, described feed-pipe 31 enters below the feed liquid liquid level of pool part in proving room.While feeding intake, marsh gas raw materials can enter the bottom of methane-generating pit completely, and it is fully fermented.
As the further improvement of technique scheme, described feed-pipe 31 is cement pipe or vitrified pipe.The feed-pipe erosion resistance that cement or pottery are made is strong, and durable.
As the further improvement of technique scheme, a draw ring 34 is set on described sealing cover 32.The draw ring more convenient sealing cover of opening is in use set.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
