Biogas intelligent temperature control system

Abstract

The invention discloses a biogas intelligent temperature control system which comprises a biogas digester, a solar water heater, a water tank, a circulating pump, a valve, a heat exchanger, a temperature sensor, a chip, an electric heating film and a heat preserving film, wherein the solar water heater is connected to the water tank; the water tank is connected to the valve and the circulating pump; the valve is connected to the heat exchanger; the circulating pump is connected to the single chip and the heat exchanger; the single chip is connected to the temperature sensor; the temperature sensor and the heat exchanger are arranged in the biogas digester; the layer of electric heating film covers outside the biogas digester; the layer of heat preserving film covers outside the electric heating film. The system disclosed by the invention can be used for solving the problem that gas output of the biogas digester is affected in case that winter in the north is too cold; the system can be used for realizing completely automatic control, and is convenient and efficient; the system, which takes solar energy as a heating source, can be used for achieving relatively ideal energy conservation; the electric heating film can be used for heating in snowy/rainy day or cloudy day; the temperature control system is uniform to heat, short in treatment duration, high in energy conversion rate and free from influence of external environment; the system performance and stability are improved, and the efficiency is obvious.

Description

technical field [0001] The invention relates to a temperature control system, in particular to an intelligent temperature control system for biogas. Background technique [0002] my country is a large agricultural country, and the rural population accounts for about 70% of the country's population. Most of the energy it consumes belongs to domestic energy. Although the annual energy consumption per person is relatively small, the amount of energy consumed is equivalent to 369.5kg of standard coal . [0003] For a long time, fuelwood and charcoal have been used as the main energy sources in rural areas. In many areas, the consumption of firewood has exceeded the growth rate of forest trees, and forest vegetation has been destroyed in a large area, which has accelerated the decline of land production capacity and even led to land desertification. Furthermore, the energy utilization rate of burning firewood and charcoal is extremely low, and the flue gas of burning will cause s...
