Problems solved by technology

[0010] 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

Embodiment Construction

[0055] The details of the present invention will be further described below in conjunction with the accompanying drawings.

[0056] A premixer structure of a biogas heater burner, in which a biogas nozzle device 2, a venturi tube 3, a premixer 4 and a biogas burner port 5 on the top are sequentially arranged on a base 1 from bottom to top.

[0057] Described premixer, its main body premixer housing 41 is capsule-shaped, and the upper end radially protrudes M radial connecting rods 48, and is fixedly connected to the inner wall of the biogas diffusion section of the venturi tube 3, and in the premixer housing The axis of 41 is equipped with a push rod part 46 that can move up and down from bottom to top. On 43, N vertically downward connecting thin rods 44 are evenly distributed in the circumferential direction with the same diameter, and the lower ends of the N connecting thin rods 44 are respectively hinged to N crankshafts with radially arranged horizontal crankshafts, and t...

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

technical field [0001] The invention belongs to the component structure of a biogas heater, in particular to a premixer device structure in a biogas heater burner. Background technique [0002] In recent years, the development of biogas has been regarded by the country as a major event to improve the living environment of farmers, improve the quality of life of farmers, and promote the adjustment of agricultural production structure, which 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 production will reach 4.5 billion tons. If such a large amount of livestock and poultry waste is improperly managed and disposed of, it 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 ma...
