Abstract
The invention relates to a mixed gas burner which can be used for solving the proportional air-gas mixing of a burner which is low burning efficiency, large in weight, high in cost and large in flow. The technical scheme of the invention is as follows: a second barrel is sleeved on the rear periphery of a first barrel, and a second annular channel is arranged between the first barrel and the second barrel; the second barrel is provided with a gas pipeline which is communicated with the second annular channel, a gas collecting cone is arranged on the rear end of the second barrel, and the rear end of the gas collecting cone is provided with a gas outlet; and a gas-distributing cone core is arranged in the first barrel, a first annular channel is arranged between the first barrel and the gas-distributing cone core, and the front end of the gas-distributing cone core corresponds to a gas inlet at the front end of the first barrel. The mixed gas burner provided by the invention has the advantages of high burning efficiency, light weight and low cost, and can be used for fully mixing large-flow air and gas.
Description
Technical field
The present invention relates to a kind of mixed gas burner.
Background technology
Coal slime oven dry industry flourish along with in recent years, for providing good development, the energy development strategy of country supports, solved the stacking of coal washing industry coal slime, pollution problem, and exchanged the regeneration of a large amount of waste resources for less cost, coal slime drying plant industry has also entered the flourish stage in recent years, burner is one of visual plant in the coal slime drying plant, its effect is that coal gas is fully burnt, fully mix with air, and burners such as conventional low thread thigh burner and sleeve burner, general coal gas feeds maximum stream flow at abundant active combustion still below 250 cubic metres per hour, per hour the problem that air and coal gas can not fully effectively mix can appear in the flow more than 250 cubic metres, efficiency of combustion is low, and conventional burners is used the cast steel casting, single burner performance is not good and weight is big, the cost height has influenced this cheap thermal source of self-control coal gas in oven dry practical application mechanically, thus improvement and innovate imperative.
Summary of the invention
At above-mentioned situation, for overcoming the prior art defective, the present invention's purpose just provides a kind of mixed gas burner, and it is low effectively to solve efficiency of combustion, and weight is big, the cost height and the air of big flow burner, the problem of the proportional mixing of combustion gas.
The technical scheme that the present invention solves is, the rear portion periphery of first cylindrical shell is set with second cylindrical shell, between first cylindrical shell and second cylindrical shell second circular passage is arranged, the gas pipeline that is connected with second circular passage is arranged on second cylindrical shell, the gas collection awl is arranged on the rear end of second cylindrical shell, and the rear end of gas collection awl is a gas vent, and branch gas coning core is arranged in first cylindrical shell, between first cylindrical shell and the branch gas coning core first circular passage is arranged, divide the front end of gas coning core corresponding with the gas entry of first barrel front end.
Efficiency of combustion height of the present invention, in light weight, cost is low, and air, combustion gas under the big flow can realize abundant mixing.
Description of drawings
Fig. 1 is a structural front view of the present invention.
Fig. 2 for the B-B of Fig. 1 of the present invention to structural front view.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated.
Provide by Fig. 1-Fig. 2, structure of the present invention is, the rear portion periphery of first cylindrical shell 3 is set with second cylindrical shell 6, second circular passage 1 is arranged between first cylindrical shell and second cylindrical shell, the gas pipeline 5 that is connected with second circular passage is arranged on second cylindrical shell, gas collection awl 7 is arranged on the rear end of second cylindrical shell, the rear end of gas collection awl is a gas vent, branch gas coning core 4 is arranged in first cylindrical shell, between first cylindrical shell and the branch gas coning core first circular passage 2 is arranged, the front end of branch gas coning core and the gas entry 8 of first barrel front end are corresponding.
Described minute gas coning core 4 partly connected as one by tapering part and stretched and constitutes, and the leading section of tapering part is plane, and the diameter of tapering part rear end is identical with the diameter of stretched part, and stretched partly is the cylinder of diameter less than first cylindrical shell; On the lower end of described gas entry 8 and gas pipeline flange is arranged all; Described gas collection awl 7 is the conulite of the both ends open that front end is big, the rear end is little, and the diameter that gas collection is bored 7 front ends is identical with the diameter of second cylindrical shell 6, and the diameter that gas collection is bored 7 rear ends is greater than the diameter of first cylindrical shell diameter less than second cylindrical shell 6; The diameter of described first cylindrical shell, 3 front ends is less than the diameter of rear end.
Working condition of the present invention is, during use, gas pipeline can link together with combustion fan, coal gas is forced to flow along first circular passage between first cylindrical shell that divides gas coning core and steel after running into branch gas coning core, the air that comes out from combustion fan is through the gas pipeline of steel, the second circular passage screw that enters along the tangential direction of first cylindrical shell of steel between second cylindrical shell of first cylindrical shell of steel and steel is advanced, air proceeds to the gas collection awl of steel and sentences the spiral status ejection, form negative pressuren zone in the place ahead of the present invention, by force and the producer gas mixing after-combustion of from the mixed gas burner, coming out, reach air with this, the well-mixed purpose of combustion gas makes producer gas be fully used.
The present invention realizes the application of this cheap clear energy sources of producer gas in oven dry machinery by the mixed gas burner, the per hour mixed gas feeding amount of autonomous Design of the present invention is greater than the mixed gas burner of 500 cubic metres super-flow, per hour feed the coal gas amount and can reach 5000 cubic metres, per hour realize that the gas generator of gas production 500--5000 cubic meter docks with single burner between the roller drier, but still can keep abundant mixed combustion, fully effectively mixed combustion under the realization super-flow between coal gas and the combustion air, mixed gas burner of the present invention has thoroughly solved big flow burner air, the proportional mixed problem of combustion gas.
