Abstract
The utility model discloses an anti-crusting device of a big-scale straw biogas digester. The device comprises a permeable barrier(1) arranged at the bottom of the biogas digester. Straw materials (2) are arranged on the upper part of the permeable barrier (1); biogas slurry is arranged at the bottom of the permeable barrier (3) and connected with a circulating pump (4); a spray nozzle (5) with a plurality of nozzles (6) is connected with the circulating pump (4); the spray nozzle (5) is arranged above the straw materials (2) in the biogas digester. The utility model increases the contact surface between the biogas slurry and the straw material through the following steps: firstly, the permeable barrier is used to separate the straw material from the biogas slurry, secondly, the circulating pump is used to enable the biogas slurry to circulate, thirdly, the circulated biogas slurry is sprayed on the straw materials through the spray nozzle so as to be in contact with the biogas slurry on the permeable barrier. In addition, compared with the prior widely-used straw biogas digester, the utility model improves the dry matter concentration of fermenting materials in the biogas digester, increases the utilization rate of digester volume is increased, and improves the gas production rate of the straw biogas digester.
Description
Technical field
The utility model belongs to treatment unit field, stalk marsh gas pond, the anti-caking housing apparatus in particularly a kind of large-scale stalk marsh gas pond.
Background technology
Current stalk marsh gas pond of promoting the use of is directly to drop into stalk in the liquid of natural pond, then at oxygen free condition bottom fermentation aerogenesis, but in the process of using, stalk can float from the liquid of natural pond, the little gas-pervious duricrust of one deck is formed at the top at methane-generating pit, the incrustive result of so a large amount of stalk can cause the biogas of methane-generating pit output not used by normal the collection, influences the normal operation of methane-generating pit.
The utility model content
The utility model provides a kind of and prevents that the stalk in the methane-generating pit from also can effectively improve the anti-caking housing apparatus of the methane-generating pit of stalk factor of created gase at natural pond liquid surface crust.
The anti-caking housing apparatus in a kind of large-scale stalk marsh gas pond, comprise a permeable interlayer that is arranged on the methane-generating pit bottom, the top of described permeable interlayer is the stalk material, the bottom is a natural pond liquid, described natural pond liquid connects a recycle pump, connect the jet pipe with a plurality of shower nozzles on described recycle pump, described jet pipe is positioned at the top of methane-generating pit stalk material.
Because the utility model adopts permeable interlayer that stalk material and natural pond liquid are separated, with recycle pump natural pond liquid is sprayed on the stalk material by jet pipe then, allow the stalk material contact with natural pond liquid at permeable interlayer, because circulating of natural pond liquid, improved the contact surface of natural pond liquid and stalk, simultaneously than current stalk marsh gas pond of promoting the use of, this device has improved the dry substance concentration of methane-generating pit fermentation raw material, increase the utilization ratio that the pond holds, improved the factor of created gase in stalk marsh gas pond.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the anti-caking housing apparatus in a kind of large-scale stalk marsh gas pond, comprise a permeable interlayer 1 that is arranged on the methane-generating pit bottom, the top of described permeable interlayer 1 is stalk material 2, the bottom is a natural pond liquid 3, described natural pond liquid 3 connects a recycle pump 4, connects the jet pipe 5 with a plurality of shower nozzles 6 on described recycle pump 4, and described jet pipe 5 is positioned at the top of methane-generating pit stalk material 2.
The bottom of described methane-generating pit is a natural pond liquid 3, natural pond liquid 3 separates with stalk material 2 by a permeable interlayer 1 that is arranged on the methane-generating pit bottom, described stalk material 2 is positioned in the gas pond, pond of hermetic seal, the epiphragma 7 that covers on the natural pond liquid 3 of pond gas pool wall, bottom and the methane-generating pit, surround a sealed space, recycle pump 4 is extracted natural pond liquid 3 out, by a plurality of shower nozzles 6 on the jet pipe 5 natural pond liquid 3 is sprayed on the stalk material 2, natural pond liquid 3 drenches downwards when reacting with stalk material 2, see through the bottom that permeable interlayer 1 enters methane-generating pit again, and then enter recycle pump 4, flow at the methane-generating pit internal recycle.
Because the utility model adopts permeable interlayer that stalk material and natural pond liquid are separated, with recycle pump natural pond liquid is sprayed on the stalk material by jet pipe then, allow the stalk material contact with natural pond liquid at permeable interlayer, because circulating of natural pond liquid, improved the contact surface of natural pond liquid and stalk, simultaneously than current stalk marsh gas pond of promoting the use of, this device has improved the dry substance concentration of methane-generating pit fermentation raw material, increase the utilization ratio that the pond holds, improved the factor of created gase in stalk marsh gas pond.
Claims (1)
1. the anti-caking housing apparatus in a large-scale stalk marsh gas pond, it is characterized in that: described anti-caking housing apparatus comprises a permeable interlayer (1) that is arranged on the methane-generating pit bottom, the top of described permeable interlayer (1) is stalk material (2), the bottom is natural pond liquid (3), described natural pond liquid (3) connects a recycle pump (4), go up a connection jet pipe with a plurality of shower nozzles (6) (5) at described recycle pump (4), described jet pipe (5) is positioned at the top of methane-generating pit stalk material (2).
