Description

Energy-saving double-flame gas burner

Technical Field

The utility model belongs to the technical field of the combustor, concretely relates to two flame gas combustion wares of energy-saving.

Background

At present, the problems of the gas burner used in the rotary kiln in the ceramsite industry are that the high-temperature area is concentrated, the skinning is easy, the operation difficulty is large, and the working condition in the kiln is complex. The existing burners used in the ceramsite industry at home and abroad are designed with a single air channel and a single air channel, and due to structural design defects, no matter how to adjust the proportioning relationship of gas and air, the flame of the burner is not enough in temperature, or causes a high-temperature area in a kiln to be too concentrated, the temperature difference between materials is too large, the sintering phenomenon is easy to generate, the operation difficulty of operators is increased, the yield and the quality of the ceramsite are reduced, and the long-period stable production is not facilitated.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an energy-saving double flame gas burner makes its rotary kiln operation difficult problem that can solve puzzlement haydite trade many years, reaches energy-concerving and environment-protective effect.

The utility model adopts the following technical scheme for accomplishing the above purpose:

an energy-saving double-flame gas burner, the double-flame gas burner has a big flame air inlet pipe and a small flame air inlet pipe which are sleeved; an air inlet gap is formed between the big fire air inlet pipe and the small fire air inlet pipe; a big fire gas pipe sleeved on the small fire air inlet pipe is arranged between the big fire air inlet pipe and the small fire air inlet pipe; the big fire gas pipe divides an air inlet gap between the big fire air inlet pipe and the small fire air inlet pipe into a big fire air inlet gap and a small fire air inlet gap; the big fire air inlet gap and the small fire air inlet gap are communicated with an air inlet main pipe arranged on a big air inlet pipe; the air inlet main pipe is hermetically connected with the big fire gas pipe; a small fire gas pipe which is coaxial with the small fire air inlet pipe is arranged in the small fire air inlet pipe; and a big fire gas inlet pipe is arranged corresponding to the big fire gas pipe.

The big fire gas inlet pipe is communicated with a gap between the big fire gas pipe and the small fire air inlet pipe; the big fire gas inlet pipe is hermetically connected with the big fire air inlet pipe.

The big fire air inlet pipe, the big fire gas pipe, the small fire air inlet pipe and the small fire gas pipe are coaxially arranged, and the required gas quantity and air distribution quantity numerical values are obtained through calculation according to the difference of the length, the rotating speed and the inclination of the rotary kiln, so that the size of each pipe is calculated.

The utility model provides an energy-saving double-flame gas burner, adopt above-mentioned technical scheme, gas channel, combustion-supporting wind are two tunnel, form two tunnel flames, combine the production situation, adjust the control flap and form all the way big fire, all the way little fire; solves the difficult problem of the operation of the rotary kiln puzzling the ceramsite industry for many years, and achieves the effects of energy conservation and environmental protection.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. the device comprises an air inlet main pipe, a big fire air inlet pipe, a 3 big fire gas pipe, a 4 small fire air inlet pipe, a 5 big fire gas inlet pipe, and a 6 small fire gas pipe.

Detailed Description

The invention is described in connection with the accompanying drawings and the embodiments:

as shown in fig. 1, the energy-saving double-flame gas burner has a big flame air inlet pipe 2 and a small flame air inlet pipe 4 which are sleeved; an air inlet gap is formed between the big fire air inlet pipe 2 and the small fire air inlet pipe 1; a big fire gas pipe 3 sleeved on the small fire air inlet pipe 4 is arranged between the big fire air inlet pipe 2 and the small fire air inlet pipe 4; the big fire gas pipe 3 divides an air inlet gap between the big fire air inlet pipe 2 and the small fire air inlet pipe 4 into a big fire air inlet gap and a small fire air inlet gap; the big fire air inlet gap and the small fire air inlet gap are communicated with an air inlet main pipe 1 arranged on a big air inlet pipe; the air inlet main pipe 1 is hermetically connected with the big fire gas pipe; a small fire gas pipe 6 which is coaxial with the small fire air inlet pipe 4 is arranged in the small fire air inlet pipe; and a big fire gas inlet pipe 5 is arranged corresponding to the big fire gas pipe 6.

The big fire air inlet pipe, the big fire gas pipe, the small fire air inlet pipe and the small fire gas pipe are coaxially arranged.

The energy-saving double-flame gas burner controls the use amount of gas and air through a valve of an external pipeline, the gas and the air are fully mixed and combusted at a nozzle of the burner through the output of a plurality of pipelines, the flame is stretched by the pressure of the air, a high-temperature area is prolonged in the rotary kiln, materials are fully heated, the situation that the materials are not prone to skinning can be achieved, and the operation difficulty is reduced.
