Abstract

The invention belongs to a component structure of a methane fan heater, and in particular relates to a methane nozzle device structure of a methane fan heater combustor. The methane nozzle device structure is characterized in that a methane nozzle device (2), a venturi (3), a premixer (4) and a methane burner nozzle (5) at the top which are arranged in sequence from top to bottom are arranged on a base (1); a methane inlet pipe (24) of the methane nozzle device (2) is horizontally and transversely connected to a nozzle seat body (25); a damper regulator (22) is arranged between a methane outlet on the nozzle seat body (25) and an inlet of the venturi (3), consists of a plurality of fan-shaped pieces the weights of which are mutually staggered, and is pressed under the elastic force of a spring arranged under the damper regulator (22); the methane pressure regulating assembly (23) is arranged in a tube hole and takes the shape of a cylinder and is provided with parts, such as a throttling regulator (234), a sealing gasket (231), a sealing elastic film (232), a bolt (235), a nut (236), a regulating spring cover (238), a regulating spring (237) and a regulating spring thread sleeve (239) which are sequentially arranged in the axial direction from inside to outside; and the throttling regulator (234) takes the shape of a rectangular frame. By utilizing the methane nozzle device structure, the purposes of complete combustion, stable combustion and high combustion value can be still achieved even if a methane source is not stable and the pressure and flow fluctuate.

Description

[0001] technical field [0002] The invention belongs to the component structure of a biogas heater, in particular to a structure of a nozzle device in a biogas heater burner. Background technique [0003] 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...
