Description
Technical field
The utility model relates to methane-generating pit.
Background technology
The methane-generating pit that present China generally uses, along with the variation in season, the variation of temperature, how many also thereupon variations of its aerogenesis, be that temperature is higher, aerogenesis is more, and temperature is lower, and aerogenesis is fewer, it is between April-October that the methane-generating pit use Best Times of burning generally is provided, November, because temperature reduces, and aerogenesis is few, burning was difficult to Second Year March (five months); The major cause of (dying) is that temperature reduces, and the organic pledge in the pond is difficult for ripe rotten the decomposition.
The utility model content
Technical problem to be solved in the utility model just provides a kind of methane-generating pit by the water cycle heating, has solved the few difficult problem of methane tank gas production under the low State of Air Temperature.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: by the methane-generating pit of water cycle heating, it is characterized in that: comprise methane-generating pit and cooling tank, described methane-generating pit comprises housing, be provided with the hot water circulation device in the described housing, described cooling tank comprises tank body, be provided with the exhaust-heat heating circulator in the described tank body, described hot water circulation device is provided with hot water inlet and cooling water outlet, described exhaust-heat heating circulator is provided with hot water outlet and cooling water inlet, wherein hot water inlet connects hot water outlet by pipeline, and cooling water outlet connects cooling water inlet by pipeline, and described hot water circulation device and exhaust-heat heating circulator are spiralling steel-tube construction.
As preferably, be provided with opening for feed on the tank body of described cooling tank, the tank body lower end is provided with feed opening, and adding in the tank body has the used heat material.
As preferably, the pipeline between described hot water inlet and the hot water outlet is provided with topping-up pump.
As preferably, described steel pipe connects into ring-type by multistage S shape steel tube.
As preferably, described steel pipe is connected into ring-type by multistage N-shaped steel pipe connecting.
As preferably, described outer wall of steel pipe is provided with fin.
As preferably, described fin is the some loop convex tendons that arrange around outer wall of steel pipe, perhaps is some axially extended ribs on outer wall of steel pipe.
The utility model is provided with the hot water circulation device in the methane-generating pit housing, be provided with simultaneously a cooling tank, be provided with the exhaust-heat heating circulator in the tank body of cooling tank, the hot water circulation device is communicated with the exhaust-heat heating circulator, wherein the hot water inlet of hot water circulation device and cooling water outlet are connected with pipeline with hot water outlet and the cooling water inlet of exhaust-heat heating circulator, consist of water cycle through the water pump effect.
Its useful effect is:
1), utilize the waste heat acceleration organic substance decomposition of used heat material to impel biogas to produce fast (the used heat material enters the waste heat that cooling tank cools off, and carries out cold and hot water circuit exchange);
2), save coal-firedly, economize on the use of funds;
3), accelerate the cooling tank cooling;
4), under low temperature condition, through cold and hot intercoursing, temperature is low again can to produce biogas equally;
