Abstract
The invention discloses a gas burner of a straw gasification heating furnace for flue-cured tobacco. The gas burner comprises an external pipe, an inlet pipe and a combustion pipe which run through the inside of the external tube, the inlet end of the inlet pipe is fixedly connected with the external pipe by a first support plate, a gas inlet channel is arranged between the external pipe and the inlet pipe, the outlet end of the inlet pipe is arranged at the inside of one end of the combustion pipe and is fixedly connected with the combustion pipe by a second support plate, a gas inlet channel is arranged between the combustion pipe and the inlet pipe, and the other end of the combustion pipe is provided with a head cover on the position of the axis of the combustion pipe, intervals are arranged between the head cover and the end part of the combustion pipe, the combustion pipe is fixedly connected with the external pipe by a third support plate, and a gas inlet channel is arranged between the combustion pipe and the external pipe. The structure causes the gas to be fully burnt, especially, the arrangement of a convex head cover causes the reflection effect to be better; the head cover can also prevent other components from damages after the combustion gas being ejected out, and can cause the combustion heat to be rapidly spread to periphery, thus achieving better heating effect.
Description
Technical field
The present invention relates to a kind of jet combustion device, specifically, relate to a kind of gas nozzle that in the tobacco flue-curing process, heats usefulness.
Background technology
Change into the required raw tobacco material of cigarette industry to the fresh tobacco leaf that the field produces, at first the fresh tobacco leaf that will be gathered in the field is modulated, and the method for thermal dehydration is adopted in the modulation of tobacco leaf more, and its thermal source has sunlight, stove fire, electric heating or the like.Wherein flue-cured tobacco mainly adopts stove fire heated baking technology.Main way is to establish a cover heating heat transmission equipment in barn cigarette-filling house outside, is provided with coal stove below, is heat exchanger above, has circulating fan that the heat that distributes is blown in the cigarette-filling house on the heat exchanger, for tobacco flue-curing provides heat energy.Along with increasing rapidly of China's economy, coal supply day is becoming tight, and is that the tobacco flue-curing cost of primary raw material is also improving with coal, and fire coal has certain influence to environment in addition, seek the fuel that substitutes coal, become the important topic of tobacco flue-curing technological improvement.In recent years, raising along with China's agricultural science and technology level, when grain yield improves constantly, the output of crop stalk is also in surge, the problem that a large amount of residue straws can't be handled has all appearred in many places, if can both can save coal straw as the tobacco flue-curing alternative fuel, can utilize stalk again, kill two birds with one stone.Stalk combustion furance all is the fuel gas that utilizes gasifying stalk to produce, and by burning of gas, produces a large amount of heats.In actual mechanical process, generally be with gas nozzle and fuel gas pipeline UNICOM, then gas nozzle is stretched into the heat radiation case, in casing, burn.But the metal tube of the general employing of gas nozzle that uses fuel gas to carry out the flame burning usually constitutes, but the gas nozzle that this metal tube constitutes not too is applicable to the flue-cured tobacco industry, because the flue-cured tobacco industry need be with combustion gas in heat radiation case internal combustion, reach purpose successively to the heating clamber air heat, the time of burning is long during therefore actual the use, common metal tube burns out easily, and, fuel gas sprays along the direction of metal tube, easily the heat radiation casing is caused damage, this unidirectional burning and injection also are unfavorable for the air heat in the heat radiation case, to reach the purpose to the heating of entire heat dissipation casing.That is to say that a large amount of heats that produce burn out gas nozzle easily in the combustion process of fuel gas, also exist gas combustion insufficient simultaneously, shortcoming such as heat exchanger effectiveness is low.
Summary of the invention
Problem to be solved by this invention is at above problem, a kind of sufficient combustion is provided, heat exchanger effectiveness is higher and long-lived a kind of flue-cured tobacco with the gas nozzle of gasifying stalk heating furnace.
For achieving the above object, the technical solution adopted in the present invention is: a kind of flue-cured tobacco gas nozzle of gasifying stalk heating furnace, it is characterized in that: comprise outer tube and through the air inlet pipe and the combustion tube of described outer tube inside, the inlet end of air inlet pipe is fixedlyed connected with outer tube by first gripper shoe, has inlet channel between outer tube and the air inlet pipe, the outlet side of air inlet pipe is positioned at the inside of combustion tube one end and fixedlys connected with combustion tube by second gripper shoe, has inlet channel between combustion tube and the air inlet pipe, the axial location that the combustion tube other end is positioned at combustion tube is provided with top cover, have between the end of top cover and combustion tube at interval, combustion tube is fixedlyed connected with outer tube by the 3rd gripper shoe, has inlet channel between combustion tube and the outer tube.
This gas nozzle is actual when using, and outer tube is connected with the box sealing of heat radiation case, so needs inlet channel fully to burn.
As a kind of prioritization scheme, the inlet end of described combustion tube is provided with connecting thread.
Further prioritization scheme, the periphery of top cover is provided with projection.
In addition further scheme, the Zhou Jing of top cover is less than the Zhou Jing of combustion tube.
Further again scheme is provided with several the 4th gripper shoes between top cover and the combustion tube, have the space between adjacent the 4th gripper shoe.
Top cover adopts the metallic plate setting of thickening.
The present invention takes above technical scheme, have the following advantages: gas nozzle is provided with top cover, top cover is connected by gripper shoe with combustion tube, when fuel gas enters the combustion tube position by air inlet pipe, a part is burnt, because gas pressure is bigger, some gas will impinge upon on the top cover, make gas to back reflective, thereby fuel gas is fully burnt, carry out sufficient heat exchange, and increased the combustion zone, especially the setting of top cover projection, make the effect of reflection better, the effect of top cover avoids burning gases to eject the back to the destruction of other member as the heat radiation case in addition, is not limited only in the burning of jet position, so the jet position is not easy to burn out, prolonged service life, the metallic plate of top cover thickening, service life is longer, has between the end of top cover and combustion tube at interval, be provided with several gripper shoes between top cover and the combustion tube, have the space between the adjacent shore plates, the heat that can make burning reaches better heating effect rapidly to diffusion all around.
The invention will be further described below in conjunction with drawings and Examples.
