Description
Technical field
The utility model is applied to the technical fields such as organic chemical industry's industry, oil refining industry, Gas Industry, metallurgy industry, is specifically related to a kind of shower nozzle of wall-attachment, for carrying out vent gas treatment to fuel gas.
Background technology
In organic chemical industry and oil refining production process, a large amount of tail gas containing many carbochains media such as butane, pentane, ethene, propylene of releasing, these gases can produce more black smoke when imperfect combustion, cause severe contamination to air.This type of burning of gas device of the existing process of prior art is rely on steam to eliminate smoke completely mostly, steaming plant complex structure installs inconvenience, and because steam dependence is very strong in use procedure, when steam supply amount is not enough or unstable, the deficiency that eliminates smoke will be caused, or waste of steam is serious, makes the inadequate environmental protection of environmental protection equipment, energy-conservation not.
Utility model content
For solving the technical problem that smoke elimination is not enough and waste of steam is serious that prior art exists, the utility model provides a kind of attached wall smoke elimination shower nozzle, and steam can not be used just can to make Thorough combustion of dropping a hint, environmental protection and energy saving.
For achieving the above object, the technical scheme that the utility model adopts is: attached wall smoke elimination shower nozzle, comprise injection air hose, convex surface nozzle and nut, the top of injection air hose and the bottom welding of air transition pipe integral, the top of air transition pipe and the bottom welding of convex surface nozzle integral, injection air hose, air transition pipe and convex surface nozzle form air duct.Convex surface nozzle is extend out horn-like, the outer wall of air transition pipe is provided with external screw thread, the upper end open of nut, the bottom of nut has the internal thread matched with air transition pipe external screw thread, and nut thread is connected on air transition pipe, nut is communicated with fuel gas inlet tube, blast tube is formed between the inwall of nut and convex surface nozzle, by rotating nut, the upper-lower position of adjusting nut, with the combustible gas discharge area in regulating gas passage and exit velocity.
When fuel gas enters nut cavity from fuel gas inlet tube, due to the wall attachment effect of gas, combustible gas cognition leaves original flow direction, changes the tendency of the surface flowing along with convex surface nozzle protrusion into.When there is mantle friction between fuel gas and its convex surface nozzle surface of flowing through, as long as curvature is little, the surface flowing that fluid can protrude along convex surface nozzle.
Because outlet fuel gas has very high speed, the air capacity of injection can be increased according to venturi principle.When in fuel gas, the gas content of many carbon component is higher, the introducing of large quantity of air can increase the mixing ratio of air and fuel gas, can realize smokeless combustion, increases the burnout rate of gas.
The bottom of injection air hose is trumpet-shapedly extend out structure, by trumpet-shaped ejecting port, a large amount of air ejections is entered combustible gas centre, increases the mixed volume of air.
Injection air hose, convex surface nozzle, nut, air transition pipe and fuel gas inlet tube are 06Cr25Ni20 material, ensure not to be destroyed when gas combustion.
The utility model has following beneficial effect:
One, be provided with convex surface nozzle in the utility model, fuel gas along the surface flowing of protruding, and by fuel gas ejection at a high speed in the form of a ring, increases the contact area of combustible gas and air, promotes smokeless combustion.
Two, the utility model is provided with injection air hose in the outlet inside of combustible gas, by inside and outside mixing wind twice, making combustion air and dropping a hint and can ensure certain coefficient of excess, and making to drop a hint reaches best fired state, promotes smokeless combustion.
Three, the utility model no longer relies on steam to eliminate smoke, and reduces the dependence of steam, more energy-conservation more environmental protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is internal structure schematic diagram of the present utility model.
In figure, 1 is fuel gas inlet tube, and 2 is injection air hose, and 3 is air transition pipe, and 4 is nut, and 5 is convex surface nozzle, and 6 is blast tube, and 7 is air duct.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1-2, attached wall smoke elimination shower nozzle, comprise injection air hose 2, convex surface nozzle 5 and nut 4, the top of injection air hose 2 and the bottom welding of air transition pipe 3 integral, the top of air transition pipe 3 and the bottom welding of convex surface nozzle 5 integral, injection air hose 2, air transition pipe 3 and convex surface nozzle 5 form air duct 7.Convex surface nozzle 5 is horn-like for what extend out, the outer wall of air transition pipe 3 is provided with external screw thread, the upper end open of nut 4, the bottom of nut 4 has the internal thread matched with air transition pipe 3 external screw thread, and nut 4 is threaded on air transition pipe 3, nut 4 is communicated with fuel gas inlet tube 1, blast tube 6 is formed between the inwall of nut 4 and convex surface nozzle 5, by rotating nut 4, the upper-lower position of adjusting nut 4, with the combustible gas discharge area in regulating gas passage 6 and exit velocity.
When fuel gas enters nut 4 cavity from fuel gas inlet tube 1, due to the wall attachment effect of gas, combustible gas cognition leaves original flow direction, changes the tendency of the surface flowing along with convex surface nozzle 5 protrusion into.When there is mantle friction between fuel gas and its convex surface nozzle 5 surface of flowing through, as long as curvature is little, the surface flowing that fluid can protrude along nozzle, by fuel gas ejection at a high speed in the form of a ring, increase the contact area of combustible gas and air.
Because outlet fuel gas has very high speed, the air capacity of injection can be increased according to venturi principle.When in fuel gas, the gas content of many carbon component is higher, the introducing of large quantity of air can increase the mixing ratio of air and fuel gas, can realize smokeless combustion, increases the burnout rate of gas.
The bottom of injection air hose 2 is trumpet-shapedly extend out structure, by trumpet-shaped ejecting port, a large amount of air ejections is entered combustible gas centre, increases the mixed volume of air.
Injection air hose 2, convex surface nozzle 5, nut 4, air transition pipe 3 and fuel gas inlet tube 1 are 06Cr25Ni20 material, ensure not to be destroyed when gas combustion.
Fuel gas inlet tube 1 can be connected on the burner of a bull, and a burner can be connected with multiple smoke elimination shower nozzle.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should wrap within the scope of the utility model.
