Biological energy source biogas project aeration device

Abstract

The invention discloses a biological energy source biogas project aeration device which comprises a tank. An anaerobic tank A, an anaerobic tank B and a clarifying tank are arranged in the tank, a settling tank is arranged at the bottom of the tank, a tank cover is arranged at the top of the tank, a ventilation device is arranged below the tank cover, an aeration pipe is arranged inside the tank,an aeration through port is arranged on the aeration pipe, a communication pipe is arranged on the end face of the aeration through port, rotating fan blades are arranged on the inner side of the communication pipe, a filter net is arranged at the bottom of the ventilation device, an exhaust fan is arranged above the filter net, a solvent cavity is arranged above the exhaust fan, and the ventilation device is provided with a gas outlet. During aeration operation, the ventilation device is arranged to treat gas overflowing from the tank cover inside a septic tank, and air pollution caused by the fact that gas like methane and hydrogen sulfide is directly discharged into air from gaps of the tank cover is avoided; a purifying system and the tank are of an integral structure, and the gas certainly passes the purifying system when being discharged from the tank cover, so that the aeration device is safe and reliable.

Description

technical field [0001] The invention relates to an aeration device, in particular to an aeration device for bioenergy biogas engineering. Background technique [0002] Bioenergy is not only different from conventional fossil energy, but also different from other new energy sources. It has the characteristics and advantages of both, and is one of the most important renewable energy sources for human beings. Bioenergy refers to the renewable energy that converts biomass, water or other inorganic substances into combustible gases such as biogas and hydrogen or combustible liquids such as ethanol and oil through biological activities. [0003] Biogas, as the name implies, is the gas in swampy wetlands. People often see that in swamps, sewers or cesspools, there are bubbles coming out. If we strike a match, it can be ignited. This is the naturally occurring methane. From the perspective of scientific definition, biogas is a kind of combustible gas produced by the fermentation o...

Problems solved by technology

[0004] The existing septic tanks are all buried underground, and the cover of the septic tank is flush with the ground. However, there must be a certain gap in the connection between the cover and the septic tank of the existing septic tank technology, so there will be A small amount of methane and hydrogen sulfide gas leaks out of the gap, which pollutes the surrounding air and is harmful to human health
