Description

The permanent fortune of high temperature is efficiently buried the ground methane-generating pit in civilian

Technical field:

This utility model relates to the permanent fortune of a kind of middle high temperature and efficiently buries the ground methane-generating pit.

Background technology:

The buried methane-generating pit of normal low temperature is still generally adopted in China rural area, the use of this buried normal low temperature cell type, the influence that changed by landing pit, season, climate temperature to a certain degree, the temperature variations of the basic running condition in this pond fermented liquid in the annual pond of China's southern area is 10 ℃-30 ℃, and the temperature variations of fermented liquid is 6 ℃ in the annual pond of the northern area of China (northeast, northwest)---25 ℃.The leavening temperature of biogas is in 8 ℃ above freezing-60 ℃ of scopes above freezing, is that the high yield gas rate is high more more for temperature therebetween.The operating temperature of buried normal low temperature cell type is as the criterion by the highest 30 ℃ of scopes, has also just just reached half effect of 60 ℃ of scopes.Second half remains to be developed.In the actual motion in the pond, China south temperature reach 25 ℃-30 ℃ situation and also have only 7-8 month, temperature is only at 10 ℃-24 ℃ in individual month the pond of remaining 4-5.The cold district of northern China with the pond in temperature also can only move 5-7 month 8 ℃-25 ℃ situation, in remaining 5-7 month, the temperature in the pond is only at 8 ℃---15 ℃.The situation of the extremely frigid zones of China is just more pessimistic, also just keeps operation 4-5 month under with 8 ℃ of-22 ℃ of situations about being as the criterion.Temperature is 8 ℃-10 ℃ will account in month 7-8 month, and factor of created gase is extremely low during this period, can't use, and just adds the protection insulation.Extremely frigid zones is built in the livestock and poultry houses or the methane-generating pit in the green house of vegetables also prolongs one month only, and operating temperature effect situation also not really desirable, time-consuming, take and expects that cost is high, efficient is very little.Moreover this methane-generating pit that reaches in the green house of vegetables in the livestock and poultry house of building in is moved factor of created gase because of covering the influence that keeps off the sun to a certain degree when moving to summer.In sum, the natural pond can exploitation, popularize in China rural area and to have certain degree of difficulty really.Especially the cold district in northern China is the devil, and What is more is China's extremely frigid zones.
