Problems solved by technology

However, most of the existing anaerobic digestion devices can only set one fermentation temperature. If a control or parallel test is to be carried out, a plurality of test devices must be used to carry out tests at the same time or a test device must be tested for many times, which will not only consume energy and cost, but also consume longer time
In addition, due to the influence of subjective factors in each test condition, the comparability of multiple test results is also poor

Abstract

The invention discloses a constant temperature water tank for the triple-connected independent temperature control anaerobic digestion methane-producing test and a control method, and belongs to the technical field of test devices. The constant temperature water tank comprises three independent stainless steel tank bodies connected together, and a lockable cover body which is hinged to the top ends of the tank bodies and is provided with supporting rods; a stainless steel bracket capable of enabling an anaerobic digestion tank to be located below the liquid level is arranged in each tank body; electric heating wires and stainless steel pipes are arranged at the bottoms of the tank bodies; a temperature sensor is sealed in each steel pipe; the electric heating wires and the temperature sensors are connected to a digital display temperature controller on the outer walls of the tank bodies. According to the constant temperature water tank disclosed by the invention, the three independent constant temperature water tanks connected together are used for researching the influence of temperature on the anaerobic digestion methane-producing efficiency, and the digital display temperature controller is used for controlling temperature changes in the three water tanks; three groups of tests can be carried out at the same time, so that the energy and the test time are saved; the constant temperature water tank can be further used for parameter comparison and analysis of the parallel tests. A test result of the constant temperature water tank is more precise and credible.

Description

technical field [0001] The invention relates to the technical field of test devices, in particular to a constant-temperature water tank and a control method for a three-connected independent temperature-controlled anaerobic digestion biogas test. Background technique [0002] The first prerequisite for efficient biogas production using anaerobic digestion of biomass raw materials is to maintain the activity of methane bacteria in the reaction system. Because methane bacteria in anaerobic digestion system are very sensitive to temperature changes, temperature is the main factor affecting anaerobic digestion. Therefore, the technical key of anaerobic digestion of biomass raw materials into biogas products is to keep the reaction temperature constant. [0003] In addition, in order to study the effect of temperature on the efficiency of biogas production by anaerobic digestion, it is necessary to control the temperature as a variable, conduct multiple control or parallel exper...
