The application number is 201510061200.2, the name of the secondary combustion type energy-saving combustor is that fuel is combusted once at a combustion head, unburned materials after primary combustion are combusted secondarily after passing through a secondary combustion disc with higher temperature, so that the combustion is sufficient, energy saving and high efficiency are achieved, but the energy-saving combustor has the defect that the combustion disc is required to be used, the combustion disc is required to be kept in a high-temperature state, and the energy consumption is relatively high.
Disclosure of Invention
Aiming at the situation, in order to overcome the defects of the prior art, the utility model provides the heat accumulating type low-nitrogen mixing device, which effectively solves the problems that the secondary combustion energy consumption of the existing burner is large and the uniform mixing cannot be realized.
In order to achieve the above purpose, the technical scheme of the utility model is as follows: the heat accumulating type low-nitrogen mixing device comprises a combustion chamber, wherein a gas pipe is arranged on the left side of the combustion chamber, and a first nozzle is arranged at the upper end of the gas pipe;
an exhaust pipe is arranged on the right side of the combustion chamber, and a second nozzle is arranged at the upper end of the exhaust pipe;
and the right side of the exhaust pipe is connected with a mixing device.
Preferably, the mixing device comprises an air outlet pipe connected with the air outlet pipe, and rifling is arranged on the inner wall of the air outlet pipe.
Preferably, the outlet end of the air outlet pipe is connected with a mixing chamber, and the space in the mixing chamber is enlarged and then reduced from left to right.
Preferably, the outlet end of the air outlet pipe is connected with a mixing chamber, and the transverse cross section of the inner space of the mixing chamber is larger than that of the air outlet pipe.
Compared with the prior art, the utility model has the following advantages: 1) Secondary ignition is carried out through the second nozzle, so that the structure is simple and energy is saved; 2) Rifling is arranged in the air outlet pipe, so that the mixing time is prolonged, and the mixing is more uniform; 3) The arrangement of the mixing chamber further improves the uniformity of mixing.

FIG. 2 is a schematic view of the structure of the air outlet pipe of the present utility model;
FIG. 3 is a schematic view of a mixing chamber of the present utility model in partial cross-section;
in the figure: 1. a combustion chamber; 2. a gas pipe; 3. an exhaust pipe; 4. a mixing device; 5. an air outlet pipe; 6. a mixing chamber.
Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic views illustrating the basic structure of the present utility model by way of illustration only, and thus show only the constitution related to the present utility model.
Referring to fig. 1-3, the technical scheme of the present utility model is as follows: the heat accumulating type low-nitrogen combustor comprises a combustion chamber 1, wherein a gas pipe 2 is arranged on the left side of the combustion chamber 1, and a first nozzle is arranged at the upper end of the gas pipe 2;
an exhaust pipe 3 is arranged on the right side of the combustion chamber 1, and a second nozzle is arranged at the upper end of the exhaust pipe 3;
the right side of the exhaust pipe 3 is connected with a mixing device 4.
In the utility model, the first nozzle and the second nozzle are used as a long open flame to ignite, air and fuel gas are combusted in the combustion chamber 1, and the combustion is insufficient, so that the secondary ignition is carried out on the mixed gas after the combustion through the second nozzle, and the secondary combustion is carried out on the part of the gas, thereby reducing the generation of nitrogen oxides, the combusted gas is fully mixed through the mixing device 4, and then required fireworks are emitted through the combustion head.
The mixing device 4 comprises an air outlet pipe 5 connected with the air outlet pipe 3, and rifling is arranged on the inner wall of the air outlet pipe 5.
In the utility model, the rifling is arranged in the air outlet pipe 5, so that the contact surface and the circulation time of the mixed gas in the air outlet pipe 5 are increased, and the mixing is more uniform.
The outlet end of the air outlet pipe 5 is connected with a mixing chamber 6, and the space in the mixing chamber 6 is enlarged and then reduced from left to right.
In order to make the mixing more uniform, a mixing chamber 6 is specially provided, and the cross section of the mixing chamber 6 is gradually enlarged from left to right and then reduced, so that the uniformity of the mixing can be increased.
The outlet end of the air outlet pipe 5 is connected with a mixing chamber 6, and the transverse cross section of the inner space of the mixing chamber 6 is larger than that of the air outlet pipe 5.
The cross-sectional area of the interior of the mixing chamber 6 is larger than that of the air outlet pipe 5, so that the effect of decelerating and mixing can be realized.
