Solar constant-temperature biogas reaction device

Abstract

The invention discloses a solar constant-temperature biogas reaction device. The solar constant-temperature biogas reaction device comprises a feeding inlet, a feeding pump, a reaction pot, a gas conveying pipe, a gas storage tank and a gas discharge outlet. The feeding inlet is connected to the reaction pot by the feeding pump. The reaction pot is connected to the gas storage tank by the gas conveying pipe. The side wall of the gas storage tank is provided with the gas discharge outlet. The solar constant-temperature biogas reaction device also comprises a solar water heater, a temperature sensor, a temperature controller, a water pump, a heating pipe and a hot water buffer. The solar water heater is connected to the hot water buffer. The temperature sensor is arranged in the hot water buffer. The temperature sensor is electrically connected to the temperature controller. The hot water buffer is connected to the water pump by a pipe. Water in the hot water buffer is pumped into the heating pipe in the reaction pot by the water pump. The solar constant-temperature biogas reaction device provides an appropriate temperature needed by a fermentation reaction, improves fermentation reaction efficiency, keeps a constant temperature in a fermenting tank, does not change with season change, guarantees a stable gas generation rate and is conducive to biogas use.

Description

technical field [0001] The invention relates to a biogas reaction device, in particular to a solar constant temperature biogas reaction device. Background technique [0002] Energy is an important restrictive factor for the progress of human society and economic development, so all countries in the world put energy issues at the top of their national economies. The application of biogas technology provides an effective way to solve the energy crisis. Biogas technology can reduce and degrade organic pollutants. It is a biological treatment method for energy recovery. It not only makes full and reasonable use of various industrial and agricultural wastes, but also protects and improves the agricultural ecological environment and maintains the agricultural ecological balance. [0003] However, currently my country's biogas production is mainly concentrated in rural areas. Biogas is produced by building biogas pools underground, and the fermentation temperature is mostly norma...

AI Technical Summary

Problems solved by technology

Biogas is produced by building biogas tanks underground, and the fermentation temperature is mostly at room temperature. The fermentation process is slow and the efficiency is low.

Moreover, with the change of temperature throughout the year, the pool temperature changes greatly, and the gas production rate also changes greatly, which will seriously affect people's need for stable utilization of biogas.
