Abstract
The invention discloses a negative pressure type high temperature burner which comprises a burner shell and a burner core, wherein the burner core is composed of two breather pipes which are arranged in a cross intersecting manner; the central parts of the two breather pipes are mutually communicated; one end of one breather pipe is connected with a fan; the other end of the breather pipe serves as a burner port; one end the other breather pipe is connected with a volatile matter recycling device of a kiln; and the other end of the other breather pipe is arranged inside the kiln body. By utilizing the burner, through the cone-column-cone tube structure of the breather pipe, the negative pressure is generated in the combustion air in the tube body so as to drive the fuel to enter the kiln body in high pressure and high speed, so that the ignition rate and the heat preservation are improved; the burner is communicated with the gas channel of the kiln through a gas collecting pipe, the gas channel is communicated with the volatile matter receiving device of the kiln, the volatile matter dissolved from the kiln is used as the fuel, and the fuel enters the kiln to be combusted under the driving of the combustion air, so that not only are the energy saved and pollution and waste reduced, but also the investment of fuel fund is reduced, and the cost of products is reduced.
Description
Technical field
The present invention relates to fuel burner nozzle, particularly a kind of suction type high temperature burner that is applicable to the coal sintering kiln that a kind of heating furnace uses.
Background technology
At present, the high temperature burner that in heating furnace, uses, generally be to be equipped with according to actual needs combustion fan, combustion air pipeline, fuel pressurization to the erecting bed and to carry pipe fitting and the igniting monitor controller, although can assemble as required, but time-consuming taking a lot of work, the fuel that is used with it mostly is natural gas.In the sintering process of coal, formed coke, also need to use burner in the kiln, the raw materials such as the natural gas that uses act as a fuel, and are cold airflow through the combustion-supporting gas that enters behind the burner in the kiln, can affect temperature in the kiln.In addition, burner head in traditional burner is the cylinder conical structure, but other conveying pipe fitting is cylindrical tube, under the drive of combustion air, fuel is sent in the body of heater, and pressure is less when still entering owing to fuel, light a fire not thorough, the slow defective of rate of warming usually appear, not only affect efficient and the effect of heating, and affect job schedule, incur loss through delay production.
Summary of the invention
The present invention be directed to the defective that existing high temperature burner exists, provide a kind of and not only can increase pressure and the speed that combustion gas enters body of heater, and the combustion-supporting gas that enters in the body of heater is the suction type high temperature burner of high temperature gas flow.
Realize above-mentioned purpose by the following technical solutions: a kind of suction type high temperature burner, comprise burner shell and the burner core that places the burner enclosure, described burner core is made of the ventilation body of two right-angled intersection settings, and the centre of two ventilation bodys is interconnected; Wherein an end of a ventilation body is connected with blower fan, and the other end places body of heater inner; The two ends of another ventilation body are connected with fuel channel by discharge respectively.
Compare with existing burner, this burner is by the pipe structure of the circular cone-cylinder-circular cone of ventilation body, and combustion air produces negative pressure in body, drives fuel with high pressure, enter in the kiln body of heater at a high speed, improves lighting rate and heat insulation effect; This burner is communicated with the blast tube of kiln by discharge, this blast tube is communicated with the volatile recovery system of kiln, the volatile matter of separating out with kiln acts as a fuel, under the drive of combustion air, enter and carry out in the kiln body in burning, energy savings not only, reduce and pollute and waste, and reduce the input of fuel fund, reduce product cost.
As preferred version:
The tracheae body comprises the diffuser of the compression section of taper, columniform trunnion and taper.
The interspersed setting of trunnion at two ventilation body middle parts, and trunnion inside is interconnected.
Along gas flow, described taper compression section is positive pyramidal structure, and described taper diffuser is inverted cone-shaped structure.
Plug-in mounting one combustion head in the connector of burner core and gas pipeline, the end of combustion head is provided with the combustion gas adpting flange.
Fuel channel is the conveyance conduit of the heat reclaim unit of kiln.
The fuel channel and at least a fuel that are communicated with ventilation body two-port.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is burner cored structure schematic diagram.
Among the figure: mounting flange 1, blower fan adpting flange 2, burner core 3, burner shell 4, air port 5, diffuser 6, trunnion 7, combustion gas adpting flange 8, compression section 9, jet 10.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
Referring to accompanying drawing 1, the burner that present embodiment is installed take level is as example.This suction type high temperature burner disclosed by the invention, comprise burner shell 4 and the burner core 3 that places burner shell 4 inside, burner core 3 is made of the ventilation body of two right-angled intersection settings, and the ventilation body is divided into taper compression section 9, cylindrical trunnion 7 and taper diffuser 6.Cylindrical trunnion 7 interspersed settings the at two ventilation body middle parts, and trunnion 7 inside are interconnected.Take accompanying drawing 2 as example: the upper port of the ventilation body that vertically arranges is as the air port 5, the burner shell is connected with blower fan by blower fan adpting flange 2, air port 5 on the body is connected with the airduct of blower fan, the lower port of the ventilation body that vertically arranges is jet 10, it is inner that this jet 10 is arranged on the kiln body of heater, installs and fixes by the burner block on mounting flange 1 and the body of heater.The two ends of horizontally disposed ventilation body are connected with fuel channel by discharge respectively, plug-in mounting one combustion head in the connector of burner core and gas pipeline, the end of combustion head is provided with combustion gas adpting flange 8, combustion gas adpting flange 8 directly is connected with discharge, with fuel channel and at least a fuel that ventilation body two-port is communicated with, other port can use simultaneously or distinguish independent use, and port time spent is not arranged, available blast cap covers, and guarantees sealing effectiveness.Fuel channel is the conveyance conduit of the heat reclaim unit of kiln in the present embodiment.Combustion head is that cylindrical tube and conical body combine, and for the control fuel flow rate, on the combustion gas adpting flange volume adjusting apparatus can be set.When practical operation, the air quantity of the combustion air that blower fan causes is less than the air quantity of fuel, and the trunnion position is the strongest position of body pressure.
The taper compression section is positive pyramidal structure, and described taper diffuser is inverted cone-shaped structure.
In the present embodiment, ventilation body among the present invention is to be made according to venturi tube structure, behind fan starting, combustion air moves from top to bottom, and combustion gas moves from left to right, after the two mixes in the trunnion position that connects, under the combustion air of blower fan drove, combustion gas was sprayed into body of heater by the lower port of vertical body, because combustion gas is the volatile materials of the recovery of kiln output, has high heat, so think high-order air-flow after under the drive of combustion air, entering in the kiln body.
