Abstract

The utility model relates to a burning torch pipe fitting for a complete mixing swirl burner, which comprises a pipe body, an air pipe connector, a combustible gas pipe and a secondary swirl mixing unit. The wind pipe connector is connected with the upper end of the pipe body; a burner interface is arranged at the bottom end of the pipe body; the combustible gas pipe is arranged on the side wall of the air pipe connector; the secondary swirl mixing unit is arranged on the middle part of pipe body positioned above the burner interface; two metal swirl plates are arranged in the inner cavity of the secondary swirl mixing unit; an elbow connector is arranged at the upper end of the pipe body, and the upper end of the pipe body is then connected with the air pipe connector; a plurality of round through holes are arranged on the upper surface of each metal swirl plate; and a plurality of skewed teeth with the same inclination angle are arranged at the edge of the metal swirl plate. The burning torch pipe fitting arranges the secondary swirl mixing unit to enable gas compounding ratio to be more reasonable, and achieves the purposes of complete combustion of fuel and saving cost. The burning torch pipe fitting has the CO emission amount of 200 ppm/m3, which completely meets the energy-saving and emission-reduction requirements.

Description

A kind of burning torch pipe fitting of full mixing swirling flow burner

Technical field

The utility model relates to the gas combustion technical field, relates in particular to a kind of burning torch pipe fitting of full mixing swirling flow burner.

Background technology

Burning torch is usually used in general burner apparatus and has multiple different structure.For example, the burning torch of industrial burner can divide to be had band combustion air formula and not to be with the combustion air formula, it is described that the former is made up of the insulating support of central tube, outer tube, ignitor, high-voltage conducting wires and airflow hole, the latter then is made up of gas supply pipe, high-voltage conducting wires, ignitor and high-voltage conducting wires etc., and these two kinds of burning torches have all generally that loss of ignition, security are lower, constant product quality and the relatively poor defective of functional reliability; The more existing burning torch device that is applicable to the ceramic roller kiln combustion furnace, before imflammable gas enters fire-resistant burner, unreasonable because of its mixing match, do not have fully to mix, do not reach desirable combustion ratio, so just wasted the material energy greatly, increased production cost; In addition, in the discharge standard that also can't reach the existing 1000CO PPM/ in world cubic meter aspect the energy-conservation discharging.

The utility model content

At above defective, the purpose of this utility model provides a kind of burning torch pipe fitting with full mixing swirling flow burner of secondary cyclone immixture, unreasonable with the imflammable gas proportioning that overcomes existing product, waste energy, cost is higher, discharge capacity is not up to standard deficiency.

For achieving the above object, the utility model is by the following technical solutions:

A kind of burning torch pipe fitting of full mixing swirling flow burner, comprise body, airduct supporting, Gas Pipe, secondary swirling flow mixed cell, the upper end of described body connects the airduct supporting, the bottom of body is provided with the burner interface, the sidewall of described airduct supporting is provided with the Gas Pipe of band air mixture passage, the middle part that is positioned at burner interface top body is provided with secondary swirling flow mixed cell, and the inner chamber of described secondary swirling flow mixed cell is provided with two metal whirlwind sheets.

Be provided with the bend pipe supporting between described body and the airduct supporting.

Described secondary swirling flow mixed cell is made up of two metal whirlwind sheets, each metal whirlwind sheet upper surface is equipped with some manholes, the edge of metal whirlwind sheet gets out some helical teeth, and the thickness of described metal whirlwind sheet is 8mm, and the spacing between two metal whirlwind sheets is set to 20mm.

The beneficial effect of the burning torch pipe fitting of full mixing swirling flow burner described in the utility model is: before gas enters fire-resistant burner, by secondary swirling flow mixed cell is set, make that gas (air and fuel gas) proportioning is more reasonable, thus the purpose that reaches full combustion of fuel and save cost; Discharge capacity can reach 200 CO PPM/ cubic meters, and the existing 1000 CO PPM/ cubic meter discharge standards well below the world meet the requirement of energy-saving and emission-reduction fully; The structure connection is fastening, service life is longer.

Description of drawings

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is the structural representation of the described burning torch pipe fitting of the utility model embodiment;

Fig. 2 is the metal whirlwind sheet combination schematic diagram of the described burning torch pipe fitting of the utility model embodiment;

Fig. 3 is the perspective view of the described burning torch pipe fitting of the utility model embodiment.

Among the figure:

The specific embodiment

As Fig. 1 and shown in Figure 3, the burning torch pipe fitting of the described full mixing swirling flow burner of the utility model embodiment, comprise body 1, airduct supporting 2, Gas Pipe 3, secondary swirling flow mixed cell 4, the upper end of described body 1 connects airduct supporting 2, the bottom of body 1 is provided with burner interface 5, the sidewall of described airduct supporting 2 is provided with the Gas Pipe 3 of band air mixture passage 6, and an end of described Gas Pipe 3 is communicated in the inner chamber of airduct supporting 2; The middle part that is positioned at burner interface 5 top bodys 1 is provided with secondary swirling flow mixed cell 4, and the inner chamber of described secondary swirling flow mixed cell 4 is provided with two metal whirlwind sheets 10 that can produce gas swirling flow immixture; Be provided with bend pipe supporting 11 between described body 1 and the airduct supporting 2, fixedly connected by flange assembly 9 between described bend pipe supporting 11 and the airduct supporting 2; The inboard sidewall of described airduct supporting 2 is provided with some internal threads 7, and the Gas Pipe 3 of airduct supporting 2 outsides is provided with some external screw threads 8.

As shown in Figure 2, the burning torch pipe fitting of the described full mixing swirling flow burner of the utility model embodiment, described secondary swirling flow mixed cell 4 is made up of two metal whirlwind sheets 10, each metal whirlwind sheet 10 upper surface is equipped with some manholes 13, and the edge of metal whirlwind sheet 10 gets out the identical some helical teeth 12 in angle of inclination; The thickness of described metal whirlwind sheet 10 is 8mm, spacing between two metal whirlwind sheets 10 is set to 20mm, and two metal whirlwind sheets 10 are set to its through hole makes the gas combustion that finally enters fire-resistant burner get more abundant so that produce effective swirling flow effect about in the of 13 corresponding staggering.

As shown in Figure 3, the burning torch pipe fitting of the described full mixing swirling flow burner of the utility model embodiment, according to the different demands under the different situations, under the situation that bend pipe supporting 11 is not set, the upper end of described body 1 can directly connect airduct supporting 2.
