Greenhouse "Sanmao" distribution system

Abstract

The invention discloses a distribution system for three biogas pools of greenhouses. The distribution system comprises the plurality of greenhouses, wherein each greenhouse is internally provided with at least one biogas pool; water pressure rooms of the biogas pools are communicated with a liquid storage tank respectively; the liquid storage tank is communicated with a liquid distribution tank through a pipeline C; the bottom of the liquid distribution tank is communicated with a biogas liquid vertical pipe through a pipeline D; a biogas pipe A is arranged on a side wall of an opening of each biogas pool, and each biogas pipe A is used for communicating a gas cell in the corresponding biogas pool with a gas storage tank; the gas storage tank is communicated with a biogas output pipe through a biogas pipe B; an anti-floating net is arranged under a liquid surface of fermentation liquid in each biogas pool, and each anti-floating net is arranged at the bottom of a sleeve, which slides up and down on a vertical rod, through a framework rod; a connection rod is arranged under each framework rod; the framework rods and the sleeves, the connection rods and the framework rods, as well as the connection rods and the vertical rods are in rotary connection through pin shafts. With the adoption of the structure disclosed by the invention, biogas liquid automatically flows into the liquid storage tank through biogas pressure, and automatically flows into each greenhouse through the liquid distribution tank, so that labor force and power are saved.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of "three biogases", in particular to a distribution system for "three biogases" in greenhouses. Background technique [0002] Greenhouse cultivation has been widely used at present. During the growth of plants, there will be some plants that are not growing well or are rotten; in addition, during the picking process, there will be dead leaves, damaged plants, and when some plants are picked, basically only part of the plant structure is picked, such as Some plants only pick fruits, some plants only pick stems and leaves, some plants only pick rhizomes, and the rest can only be discarded. These can be used as raw materials for biogas production. If they are discarded directly, it is wasteful and must be cleaned up. Going out of the greenhouse is also time-consuming and labor-intensive. However, these materials are relatively trivial. If they are directly used for fermentation, not only w...

During the growth of plants, there will be some plants that are not growing well or are rotten; in addition, during the picking process, there will be dead leaves, damaged plants, and when some plants are picked, basically only part of the plant structure is picked, such as Some plants only pick fruits, some plants only pick stems and leaves, some plants only pick rhizomes, and the rest can only be discarded. These can be used as raw materials for biogas production. If they are discarded directly, it is wasteful and must be cleaned up. Getting out of the greenhouse is also time-consuming and labor-intensive

However, these materials are relatively trivial. If they are directly used for fermentation, not only will a large amount of space in the biogas digester be occupied, but they will also float on the surface of the fermentation liquid, which will also cause crusting and affect the production. air effect

And because the amount of biogas and biogas produced by biogas digesters in a single greenhouse is not the same, the amount of biogas and biogas in some greenhouses is excessive, and the amount of biogas in some greenhouses is not enough, so it is necessary to carry out overall distribution to meet the needs of biogas slurry, biogas and even biogas residue in each greenhouse
