Abstract
The invention discloses a petroleum coke powder oxygen-fuel combustion gun. The petroleum coke powder oxygen-fuel combustion gun comprises a body and is characterized in that a flat petroleum coke powder outlet, an oxygen outlet and an auxiliary oxygen outlet are formed in the left of the body, the petroleum coke powder outlet and the oxygen outlet are located in the upper portion, the auxiliary oxygen outlet is located in the lower portion, and the oxygen outlet is connected to the exterior of the petroleum coke power outlet in a sleeved mode. Due to the design of the combustion gun, not only can petroleum coke power be fully combusted, but also emission of nitride is reduced. Along with popularization and application of petroleum coke power oxygen-fuel combustion control systems, the petroleum coke powder oxygen-fuel combustion gun will be further popularized to the industries of glass furnaces, metallurgical industry, forging and the like.
Description
Technical field
The present invention is a kind of petroleum coke powder all-oxygen combustion rifle, is a kind of novel combustion tool of making for petroleum coke powder all-oxygen combustion control system specially.
Background technology
Petroleum coke powder replaces heavy oil from float glass industry application for a long time, and application is thereon petroleum coke powder+air-breathing mostly, and air driven petroleum coke powder directly enters body of heater burning.Yet this mode exists problems, first, in environmental protection, in surpassing the high temperature furnace of 1200 ℃, can there is chemical reaction and generate nitrogen oxide, contaminated environment in the nitrogen of air.Secondly, 21% of an airborne oxygen duty gas, namely only have 21% oxygen can and petroleum coke powder in conjunction with combustion-supporting, in other all go to sky as toxic emission, and take away a part of heat.Again, air-breathing mode is difficult to make petroleum coke powder combustion abundant, thereby produces energy waste and leave over unburning material.
Use pure oxygen and petroleum coke powder in conjunction with the above difficult problem of having burnt with regard to customer service.Traditional common burning rifle can not meet the specification requirement of petroleum coke powder all-oxygen combustion, so occur being exactly corollary with the burning rifle of pure oxygen and petroleum coke powder mixed combustion.
Summary of the invention
In order to overcome the drawback of traditional air and petroleum coke powder combustion mode, patent of the present invention is to aim at a kind of petroleum coke powder all-oxygen combustion rifle that the combustion system of pure oxygen and petroleum coke powder provides.
Object of the present invention is carried out specific implementation by the following technical programs:
A kind of petroleum coke powder all-oxygen combustion rifle, comprise body, in the left side of body, be provided with petroleum coke powder outlet, oxygen outlet and the outlet of auxiliary oxygen of flat, wherein said petroleum coke powder outlet, oxygen outlet are positioned at top, described auxiliary oxygen outlet is positioned at bottom, and described oxygen outlet is socketed on the outside of described petroleum coke powder outlet.
At the center, right side of body, be provided with the gas inlet being communicated with described petroleum coke powder outlet.
In the both sides of described gas inlet, be respectively equipped with an oxygen intake.
At petroleum coke powder outlet front end, oxygen premix interface is set, for being pre-mixed part of oxygen before petroleum coke powder ejection.
Burn rifle and be provided with upper and lower oxygen proportion adjusting knob, can regulate the ratio of oxygen in auxiliary oxygen outlet and oxygen outlet.
Petroleum coke powder outlet is flat, and its outlet is in inner side; And oxygen outlet is also flat, be looped around the outside of petroleum coke powder outlet.When petroleum coke powder and oxygen are when burning the outlet ejection of robbing, oxygen can form one " gesture of encirclement " to petroleum coke powder, and the two can fully be mixed.
Described auxiliary oxygen outlet is in bottom, and be also flat, its effect is the oxygen proportion that regulates upper and lower two oxygen outlets, can adjust flame length on the one hand, make on the other hand the mixing of flame lower surface oxygen and petroleum coke powder more abundant, make flame temperature of lower higher than flame upper surface temperature, strong for the heat radiation of metal level, little for upper space heat radiation.
Petroleum coke powder outlet, oxygen outlet and the outlet of auxiliary oxygen are divided into two-layer up and down, last layer is the outlet of described oxygen outlet and petroleum coke powder, and petroleum coke powder exports in inner side, oxygen outlet in outside and surrounding around petroleum coke powder, export, the auxiliary oxygen outlet in bottom is in both bottoms, i.e. lower floor.
Because petroleum coke powder is flour, must lean on the gas of high flow rate to drive can be at Flows.The front-end pipelines of this burning rifle is to drive petroleum coke powder to enter burning rifle through piping with compressed air or natural gas.
This burning gets the jump on petroleum coke powder outlet front end oxygen premix interface is set, and at petroleum coke powder, is about to enter the leading portion of outlet, and an oxygen interface is set.So just can increase the amount of oxygen that petroleum coke powder drives gas, reach both and shift to an earlier date premixed and enter and burn rifle outlet.
The design of this burning rifle, has not only realized the abundant burning of petroleum coke powder, also alleviates emitting nitride.Along with the popularization and application of petroleum coke powder all-oxygen combustion control system, this burning rifle will be further generalized to the industries such as glass furnace, metallurgy, forging.

In figure: the 1st, petroleum coke powder outlet; The 2nd, oxygen outlet; The 3rd, auxiliary oxygen outlet; The 4th, upper and lower oxygen proportion adjusting knob; 5 and 6 is oxygen intakes; The 7th, natural gas entrance; 8 premix oxygen intakes.
The specific embodiment
As Figure 1-4, petroleum coke powder all-oxygen combustion rifle described in the embodiment of the present invention, comprise body, in the left side of body, be provided with petroleum coke powder outlet 1, oxygen outlet 2 and the auxiliary oxygen outlet 3 of flat, wherein said petroleum coke powder outlet 1, oxygen outlet 2 are positioned at top, described auxiliary oxygen outlet 3 is positioned at bottom, and described oxygen outlet 2 is socketed on the outside of described petroleum coke powder outlet 1.
At the center, right side of body, be provided with and described petroleum coke powder outlet 1 gas inlet being communicated with 7.
In the both sides of described gas inlet, be respectively equipped with an oxygen intake 5,6.
At petroleum coke powder outlet front end, oxygen premix interface 8 is set, for being pre-mixed part of oxygen before petroleum coke powder ejection.
Burn rifle and be provided with upper and lower oxygen proportion adjusting knob 4, can regulate the ratio of oxygen in auxiliary oxygen outlet and oxygen outlet.
Petroleum coke powder outlet is flat, and its outlet is in inner side; And oxygen outlet is also flat, be looped around the outside of petroleum coke powder outlet.When petroleum coke powder and oxygen are when burning the outlet ejection of robbing, oxygen can form one " gesture of encirclement " to petroleum coke powder, and the two can fully be mixed.
Described auxiliary oxygen outlet is in bottom, and be also flat, its effect is the oxygen proportion that regulates upper and lower two oxygen outlets, can adjust flame length on the one hand, make on the other hand the mixing of flame lower surface oxygen and petroleum coke powder more abundant, make flame temperature of lower higher than flame upper surface temperature, strong for the heat radiation of metal level, little for upper space heat radiation.
