Embodiment Construction

[0032] figure 1 and figure 2 In combination, a double-chamber plug-flow biogas anaerobic reactor is provided, which includes a cylindrical reactor main body 7, and a cylindrical cavity 70 is set in the reactor main body 7; The reactor cover plate 11 that is used to seal cavity 70, the bottom of reactor body 7 is inverted taper (as figure 1 shown).

[0033] In the cavity 70 of the reactor main body 7, a cylindrical metal cylinder 3 (the metal cylinder 3 is used as a heat dissipation cylinder) is set, and the center of the metal cylinder 3, the cavity 70 and the reactor main body 7 Axes coincide. The top 31 of the metal cylinder 3 is located outside the reactor main body 7 after passing through the reactor cover plate 11 in a sealed manner. The top 31 of the metal cylinder 3 is provided with an openable cover plate 33, that is, when refueling, the cover plate 33 can be opened; A vent hole is provided on the plate 33 to ensure that the inner cavity 32 of the metal cylinder ...

Abstract

The invention discloses a double-chamber plug-flow type biogas anaerobic reactor, comprising a reactor main body (7) with an inner cavity (70), wherein a reactor cover plate (11) for sealing the cavity (70) is arranged at the top of the reactor main body (7); a metal cylinder (3) is arranged in the cavity (70) of the reactor main body (7), the inner cavity (32) of the metal cylinder (3) is isolated from the cavity (70) of the reactor main body (7); a feed port (1), a discharge port (9) and a sample taking port (5) are respectively arranged on the side wall of the reactor main body (7); a biogas outlet (10) is arranged on the reactor cover plate (11); a drain outlet (6) is arranged at the bottom of the reactor main body (7); and a heater (4) and a temperature sensing probe I (12) are arranged in the inner cavity (32) of the metal cylinder (3). The double-chamber plug-flow type biogas anaerobic reactor has the characteristics of thorough anaerobic digestion, high biogas yield and the like.

Description

technical field [0001] The invention relates to a double-chamber push-flow biogas anaerobic reactor, which belongs to the technical field of renewable energy, in particular to the technical field of biogas engineering. Background technique [0002] The construction of biogas projects in large-scale farms is conducive to alleviating the energy shortage in rural areas and protecting the ecological environment. In recent years, the construction of China's biogas projects has been intensified, and the development speed is relatively fast. The number of large and medium-sized biogas projects in intensive farms increased from 1,500 in 2004 to 4,700 in early 2010; by the end of 2007, the number of small household biogas digesters had increased to 25 million. According to China's national medium and long-term biogas industry development goals: by 2020, the number of large and medium-sized biogas projects for livestock and poultry farms will increase to 10,000, and the number of lar...
