Abstract

The utility model relates to a mixed gas burner nozzle, comprising an inner pipe, an outer pipe and a mixing chamber. The utility model is characterized in that the inner pipe is a high pressure air channel, and a mixed gas channel is arranged between the outer pipe and the inner pipe; the inner front end of the inner pipe is provided with a helical blade. The high pressure air is helically pressed in the mixing chamber form the inner pipe, and the mixed gas is pumped in the mixing chamber. The utility model has the advantages that the air and the gas are sufficiently premixed, the nozzle is hard to be blocked, the mixed gas is completely burnt, the heat efficiency is high, etc.

Description

The mixed gas burner nozzle

A kind of mixed gas burner nozzle.

Existing mixed gas burner nozzle is that interior pipe advances mixed gas, circular passage between outer tube and the interior pipe enters air, its fault is, because the pressure of mixed gas is the mixed gas producer outlet pressure, and pressure is very low, make mixed gas and air abundant premix in mixing chamber, therefore, combustion efficiency is not good, is deposited on the sticky shape coal tar of nozzle head, and the heavy hydrocarbons material stops up burner nozzle easily.

The purpose of this utility model is, prior art is improved, provide a kind of pressure-air to enter in the mixing chamber from the passage between outer tube and the interior pipe from interior pipe, mixed gas, by pressure-air suction and pumping mixed gas, make the mixed gas burner nozzle of mixed gas and air abundant premix in mixing chamber.

Another purpose of the present utility model is, pressure-air spiral from interior pipe is pressed in the mixing chamber, and burner nozzle is difficult for stopping up, and mixed gas burner nozzle completely burns.

The purpose of this utility model is realized by following technical scheme: a kind of mixed gas burner nozzle, pipe 1, outer tube 2 and mixing chamber 5 in it comprises, its special character is: interior pipe 1 is pressure-air passage 3, is mixed gas passage 4 between outer tube 2 and the interior pipe 1.

Front end in interior pipe 1 is provided with helical blade 6.

The advantage applies of mixed gas burner nozzle of the present utility model exists:

1, because interior pipe is the pressure-air passage, be the mixed gas channel design between outer tube and the interior pipe, when pressure-air extrudes from interior tube head, and the suction and pumping mixed gas enters abundant premix in the mixing chamber together, from burner nozzle ejection burning structures, therefore, simple in structure again, easy to use, and combustion efficiency is good;

2, owing to helical blade is set, pressure-air spiral from interior pipe is pressed in the mixing chamber, and is sprayed on the internal perisporium of outer tube at interior pipe Inner Front End, can prevent that coal tar, the sticky shape material of heavy hydrocarbons are hung on the internal perisporium of outer tube, burner nozzle is difficult for stopping up, and burning is complete, thermal efficiency height.

The utility model is described in further detail to utilize embodiment shown in the drawings below.

Fig. 1 is embodiment 1 a mixed gas burner nozzle structure cross-sectional schematic.

Fig. 2 looks schematic diagram for the left side of Fig. 1.

Fig. 3 is embodiment 2 mixed gas burner nozzle structure cross-sectional schematic.

Fig. 4 looks schematic diagram for the left side of Fig. 3.

Embodiment 1: with reference to Fig. 1 and 2, pipe 1, outer tube 2 in the mixed gas burner nozzle has, interior pipe 1, outer tube 2 are fixed by the supporting rib 7 of welding, interior pipe 1 is a pressure-air passage 3, circular passage 4 between outer tube 2 and the interior pipe 1 is the mixed gas passage, and the volume of interior pipe 1 head end and outer tube 2 head ends is a mixing chamber 5.During use, mixed gas passage 4 is communicated with the mixed gas outlet of mixed gas producer by pipeline, and pressure-air passage 3 is communicated with air blast.

Embodiment 2: with reference to Fig. 3 and Fig. 4, its basic structure is identical with embodiment 1, and just the front end at interior pipe 1 is welded with some helical blades 6.Helical blade 6 is pressed in the mixing chamber 5 the pressure-air spiral, and is sprayed on the internal perisporium of outer tube 2, can prevent that burner nozzle from stopping up.
