Double-pool fermentation biogas tank with heater

Abstract

A double-pool fermentation biogas tank with a heater comprises a biogas tank, a temperature controller, the heater and a plastic cover, and is characterized in that the biogas tank comprises a tank body and a floating cover, and a sandwich wall is arranged in the middle of the tank body to divide a fermentation chamber in the tank body into two; a cover wall is also arranged in the middle of the floating cover to divide an air reservoir below the cover wall into two; the two fermentation chambers in the tank body are positioned in sealing water, so are four walls of the two air reservoir, water sealing ensures air tight of the air reservoir; the heater is arranged at the lower part of the sandwich wall of the box body and is connected with the temperature controller and a power supply through conducting wires; the plastic cover is arranged outside the biogas tank and is formed in a way that a plastic membrane is connected with a support frame. The biogas tank is placed on the ground, adopts a dry fermentation process and high and intermediate fermentation, is large in gas output, and small in size. Moreover, solar energy and other methods can be fully utilized to heat the biogas tank, so as to achieve the insulating effect, and therefore, the requirement that biogas is available all over the year in whole China, not only in the North but also in the South, is met.

Description

Technical field [0001] The invention relates to the technical field of biogas production, in particular to a biogas tank for dual-pot fermentation with a heater. Background technique [0002] At present, biogas digesters are generally built underground and sealed all year round. Each household has one tank, which is time-consuming, costly, and difficult to promote. In addition, biogas digesters are prone to leaks and gas leaks, and maintenance is difficult. There are also biogas tanks and other integrated biogas equipment, but None of them can solve the fundamental problem of the low temperature in winter, that the biogas cannot be fermented, and cannot produce biogas, which results in uneven biogas production and cannot be used for many years. Therefore, the current environmental protection technology of biogas cannot be widely promoted and applied. The main reason is that biogas production has a great seasonality. With high temperatures in summer and long sunshine hours, it pro...

Another reason is that after the biogas is fed, it still takes a while to ferment before it can be supplied, which affects the use
