Premixer structure of marsh gas fan heater burner

Abstract

The invention belongs to a component structure of a marsh gas fan heater and relates to a premixer structure of a marsh gas fan heater burner; M radial connecting rods (48) are extended in a radial direction from the upper end of a premixer shell (41) of a main body of the premixer structure and are fixedly connected at the inner wall of a marsh gas diffusion section of a Venturi tube (3); an ejector rob part (46) is arranged at the axis of the premixer shell (41) from bottom to top; the upper end of the premixer shell reaches against a horizontal balance disc (43), the upper side of the premixer shell is pushed down by an upper support spring (49); N vertical downward connecting slender rods (44) are uniformly distributed at the periphery of the same diameter of the balance disc (43); the lower end of the balance disc is respectively articulated with N radial configured horizontal cranks of crankshafts; the crankshafts are extended out of the shell wall of the premixer shell (41) in the radial direction and are respectively connected with n blades (42) in the radial direction; the lower side of the balance disc (43) is pressed upward and keeps balance; and the lower end of the ejector rob part (46) is a horizontal windward sheet (410). Therefore, no matter the outflow volume and the pressure of the marsh gas is sufficient or not, the mixer structure can fully mix the marsh gas and air automatically, thereby achieving the ideal burning effect.

Description

[0001] Technical field [0002] The invention belongs to the component structure of a biogas heater, and in particular relates to a premixer device structure in a biogas heater burner. Background technique [0003] In recent years, the development of biogas has been taken by the state as a major task to improve the living environment of farmers, improve the quality of life of farmers, and promote the adjustment of agricultural production structure. This is highlighted in the biogasification process of my country's livestock and poultry breeding industry. Experts predict that by 2010, my country’s annual livestock and poultry waste will reach 4.5 billion tons. Such a large amount of livestock and poultry waste, improperly managed and treated, will become an important source of environmental pollution. In fact, livestock and poultry waste is a good renewable organic resource, and the biogasification process (usually referred to as anaerobic digestion) is one of the main means to so...

Problems solved by technology

[0011] The biogas burner in the prior art only has a stove burner structure used in the kitchen. The lower part is a gas intake, and the upper disc-type multi-hole structure has a concentrated fire head, which is very suitable for cooking. However, the fire head is small and the flame Concentrated, but hardly suitable for large-scale and large-space heating, used as a heater for burning biogas
