Abstract
The invention belongs to the technical field of renewable energy sources, and in particular relates to a methane pressure stabilizing device and a manufacturing process thereof. The methane pressure stabilizing device is characterized by utilizing a principle of separate storage in two pools, i.e. one material fermentation device and a methane storage and pressure stabilizing device are constructed; when methane in the pools is generated continuously and the pressure of the pool bodies is increased, the methane continuously flows to a methane storage tank (2) through a methane guide pipe (8); the more the methane is generated, the higher the pressure of the methane storage tank (2) becomes; when the methane stored in the methane storage tank (2) is too much or the amount of the methane used by farmers is too small, excessive methane is drained through a pressure relief valve (3), and the pressure of the methane supplied to the farmers is unchanged; and a one-way valve (6) is installed on the methane guide pipe (8), when the methane generation amount of a fermentation pool (7) is less, the one-way valve (6) can ensure the pressure in the methane storage tank (2) and prevent methane in the methane storage tank (2) from flowing back to the fermentation pool (7), and the pressure of the methane supplied to the farmers is unchanged.
Description
Technical field
The present invention relates to the device that a kind of organic waste materials anaerobically fermenting prepares biogas, belong to field of renewable energy technology, specifically a kind of methane voltage-stabilizing device and manufacture craft.
Technical background
Biogas is the inexorable trend of following rural energy development as the high-quality renewable energy source that the rural area can generally develop, and is that one of requisite important content is built in the new socialist countryside.At present in the general methane-generating pit in China rural area; To use the house type methane-generating pit is main, and methane-generating pit is that in the effect in rural area methane-generating pit can be handled organic waste on the one hand and produce bioenergy; The ight soil that the livestock industry of can fermenting on the other hand produces is organic fertilizer; Simultaneously can completely include in and pass through anaerobism, degraded, fermentation and conversion in the methane-generating pit, have the effect that beautifies ecotope, thereby biogas become the gordian technique of new countryside construction influence pollutent in the rural environment.The principle that China methane-generating pit uses mainly is the hydraulic type fermentation technique, and the biogas air pressure that produces when anaerobically fermenting is during greater than hydraulic pressure, and the space of water is taken by biogas; When biogas air pressure during less than hydraulic pressure; Water flows to air chamber, and constitutes the balance of hydraulic pressure and air pressure, thereby makes the constant pressure of biogas.Because science and technology is flourishing day by day, methane-generating pit is also further constantly developed and is improved.But so far, the methane-generating pit that China's main flow is promoted the use of, build with use in following shortcoming is arranged: 1. need to design an opening for feed, a water outlet hold concurrently water pressure house, a removable cover, cause stopping property poor; 2. fermentation is mixed fermentation, and it is poor to exist the raw material processing, the thorough problem of fermentation; 3. because the opening for feed floor area of building is little, the opening for feed gradient is little or biogas air pressure when big, and opening for feed blocks up full water, can cause that charging is floating, charging is difficult to into the pond, charging occurs and stopped phenomenon; 4. all adopt one feeding, mixed fermentation, the pressure of biogas is regulated and control by hydraulic pressure, and the biogas pressure that makes existing methane pool produce is unstable; Along with season change management difficulty is big, changes greatly because Along with season changes surface temperature, and the velocity variations that produces biogas is also bigger, is example with the methane-generating pit of a standard; Season in full summer, the fermentation of methane-generating pit feed liquid is fast, and aerogenesis is prosperous, a lot of methane-generating pits overnight aerogenesis more than 8kpa; It is excessive to make gas chamber of marsh gas tank deposit tolerance, causes the overflow everywhere of natural pond liquid, pollutes, have in addition jack-up skylight lid or damage weather gage and work the mischief; Removable cover is often washed open or expand to be leaked, and seals badly, causes gas leakage easily; The aerogenesis speed of spring and autumn obviously reduces; Do not make troubles to peasant household's management and use and produce biogas winter.Biogas be by rotten thing of plant residue or ight soil mud etc. with the isolated situation of air under, be the inflammable gas that produces through natural decomposition under 9-60 ℃ the environment in temperature.Methane-generating pit is the microbial ecological system of relative " precision "; Build technical by force, it is strict to build pool process, keep the normal management of using the science of be unableing to do without and standard; And methane-generating pit management user is a peasant household; Therefore, must be simple and practical to the ladder of management of methane-generating pit, be prone to accepted by mass peasants.
