Problems solved by technology

[0004] However, the shortcomings of installing solar energy devices on the biogas digester to heat the biogas digester are: the heating time cannot be controlled, and the heating energy is difficult to control
However, the disadvantages of installing hot blast stoves and electric furnaces in biogas digesters are that electric energy is used to control the temperature of biogas digesters, and the operating cost is high.
When building a greenhouse on the biogas digester to achieve temperature control for the biogas digester, there are deficiencies: the heating time is uncontrollable, and the heating energy is difficult to control

Abstract

A timing temperature control device for biogas comprises a tank and a printed circuit board (PCB), wherein the tank comprises a key group used for setting time and corresponding temperatures; the PCB is arranged in the tank and comprises a single chip microcomputer (SCM), a memory and a timer; the memory is used for storing the time and corresponding temperatures set in the key group; the SCM is connected with a first temperature sensor, a concentration sensor, a heating unit, a water pump and the memory respectively, and used for obtaining the fermentation broth temperature detected by the first temperature sensor, reading the current time of the timer, obtaining corresponding set temperature according to the current time, the set time and corresponding temperature, and comparing the fermentation broth temperature with the set temperature; and if the fermentation broth temperature is smaller than the set temperature, the SCM triggers the heating unit to heat the fermentation broth to enable the fermentation broth temperature to reach the set temperature. Different temperature maintenance at different moments for a biogas digester is achieved through the device.

Description

Technical field [0001] The invention relates to the technical field of electronic control devices, in particular to a biogas timing temperature control device. Background technique [0002] Biogas digester is an applied technology widely promoted in rural areas of our country. The use of biogas can be said to be an active and effective way to use local resources to obtain energy. The use of biogas as an energy source not only involves heating the biogas digester, but also involves the temperature control and insulation of the biogas digester. [0003] At present, the methods to control the temperature of the biogas digester include: installing solar energy devices on the biogas digester to realize the heating of the biogas digester; installing hot air stoves and electric furnace devices in the biogas digester to realize the temperature control of the biogas digester; Build a warm shed to achieve insulation of the biogas digester. [0004] However, the disadvantages of installing s...
