Self-cleaning axial flow air inlet combustor

Abstract

The invention discloses a self-cleaning axial flow air inlet combustor which comprises a cylinder, an air stabilizing disk, an atomizing mechanism and an air inlet mechanism. The air stabilizing disk and the atomizing mechanism are arranged in the front of the cylinder, the air inlet mechanism is arranged in the rear of the cylinder, the atomizing mechanism comprises a sprayer and an oil gas input mechanism, the sprayer is positioned at the center of the air stabilizing disk, an atomizing chamber is formed at the front end of the sprayer, the front end of the oil gas input mechanism penetrates the atomizing chamber, the air inlet mechanism comprises an axial flow fan and a waste gas inlet pipe, the axial flow fan is arranged in the rear of the cylinder, the waste gas inlet pipe is arranged in the middle of an air inlet surface of the axial flow fan, an air inlet channel is formed between the waste gas inlet pipe and the cylinder, a one-way valve mechanism is arranged in the atomizing chamber, divides the atomizing chamber into a front section and a rear section and only allows air at the right back to circulate forwards, and atomizing holes are formed in the front side face of the atomizing chamber. By the aid of the integrated axial flow fan, the self-cleaning axial flow air inlet combustor is small in overall size, more compact in structure, low in air resistance and large in air volume, and inlet air directly reaches an air inlet disk.

Description

technical field [0001] The invention relates to the technical field of industrial waste gas treatment, in particular to a self-cleaning axial flow air-intake burner. Background technique [0002] Rubber powder modified asphalt is used to pave urban roads, highways and bridge decks, reduce and absorb noise, improve the adhesion between wheels and road surfaces, increase friction to make brakes stable, and have good anti-freezing and anti-aging effects. A large number of waste tires are recycled. However, when rubber powder is mixed with asphalt at 185°C to 195°C, a large amount of poisonous fumes such as ether, hydrogen cyanide, and sulfur dioxide will escape, and the benzopyrene contained in it is the most toxic of polycyclic aromatic hydrocarbons. Strong carcinogens are combined with aerosols formed by various types of particles in the atmosphere. Among the inhalable dust particles below 8 microns, the rate of direct inhalation into the lungs is relatively high. They are i...

Problems solved by technology

[0006] However, the treatment device in the above-mentioned patent directly uses asphalt fume to directly spray into the outer flame part of the burner flame, because the instability of the production of asphalt fume causes the combustion treatment effect to be unsatisfactory, and when the combustion is stopped, the There will be residual grease in the oil supply pipeline, which will cause poor ignition next time, resulting in deflagration, and will gradually block the oil supply pipeline of the guide post
