Abstract
The invention discloses a combustor, which comprises a fuel gas inlet pipe and is characterized in that: the fuel gas inlet pipe is transverse-H-shaped; the upper surface of the transverse-H-shaped fuel gas inlet pipe is provided with a plurality of spray heads; and at least a part of the outer edge of the transverse-H-shaped fuel gas inlet pipe is provided with a protective cover. A spray drying tower using the combustor comprises a tower body and an air inlet pipe, and is characterized in that: the combustor, an inflow air filtering device and a flame retardancy device are arranged in the air inlet pipe; and the combustor is arranged in the air inlet pipe, and is positioned between the inflow air filtering device and the flame retardancy device. The spray drying tower which is used for directly heating inflow air, has a high heating speed and high working efficiency and is driven by environmentally-friendly energy is provided, so that the heat energy utilization ratio and drying temperature of the spray drying tower are greatly raised, and super high temperature quick heating of materials is realized.
Description
Technical field
The present invention relates to a kind of novel burner and the spray drying tower that uses this burner.
Background technology
Vegetable fat powder or milk powder such as coffee; Directly can only dry its surface with heated-air drying; The inner caking that is very easy to of powder; Spray-drying is a kind of method that the systematization technology is applied to dry materials, in drying tower with solvent or diluent after atomizing, with the contacting of hot blast in; Moisture is vaporized rapidly; Promptly obtain dry products, this method can directly make solution, emulsion be dried to powdery or graininess goods, can economize operations such as devaporation, pulverizing.
The hot blast that spray drying tower is used all is through plate type heat exchanger etc. cold air and steam heat-exchanging to be made at present, and boiler can only be indirectly with air heat, have the mass energy waste and cause auxiliary device too much, many shortcomings such as complex technical process.With the coal heating, dust is many, the heat energy utilization rate is not high usually for boiler, and the temperature of heating also receives the restriction of boiler maximum tolerable pressure, can't realize superhigh temperature, Fast Heating to material.
Summary of the invention
The objective of the invention is to overcome the EAT that exists in the prior art can't improve; Steam uses the shortcomings such as not environmental protection of the energy; A kind of direct heating air intake is provided; Firing rate is fast; And use eco-friendly power source; The spray drying tower that operating efficiency is higher has improved the heat energy utilization rate and the baking temperature of spray drying tower greatly, has realized superhigh temperature, Fast Heating to material.
The technical scheme that the present invention adopts is:
A kind of burner comprises gas inlet pipe, it is characterized in that: said gas inlet pipe is I-shaped, and said I-shaped gas inlet pipe upper surface offers a plurality of injector heads, and outward flange at least a portion of said I-shaped gas inlet pipe is provided with protective cover.
Further, said protective cover upwards and is outwards expanded by the outward flange of said I-shaped gas inlet pipe.
Further, said protective cover is provided with a plurality of air vents.
A kind of spray drying tower that uses this burner; Comprise tower body and blast pipe; It is characterized in that: be provided with said burner, air intake filter and flame-retardant device in the said blast pipe, it is interior between said air intake filter and said flame-retardant device that said burner is arranged on blast pipe.
Beneficial effect of the present invention is:
1. burner of the present invention is set to I-shaped, has taken into full account the air intake space of cold air, and is provided with protective cover around the injector head; Being more conducive to flame concentrates; And a plurality of air vents are set on the protective cover, and more help cold air through heating, significantly improved the efficiency of heating surface.
2. because spray drying tower of the present invention adopts the directly burner of burning natural gas; Directly burning in airduct; The temperature of heating air intake can improve greatly; Thereby improved the powder material drying capacity; Thereby compare with the method for the employed use of prior art matchmaker heating steam heating air intake; Not only improved operating efficiency, and the energy environmental protection of using more.
3. because spray drying tower of the present invention is installed filter at the air intake arrival end; The new wind that guarantees the entering burner all is clean; At the air intake end flame-retardant device is installed, makes Mars and flammable particle can't enter in the tower, spray drying tower of the present invention can move safely and effectively.
Description of drawings
Fig. 1 is the structural representation of burner of the present invention;
Fig. 2 is the structural representation of spray drying tower of the present invention;
Fig. 3 is the structural representation of spray drying tower blast pipe of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Embodiment:
Shown in Fig. 1 to 3, a kind of spray drying tower comprises that drying tower tower body 1 and outlet are arranged on the feed pipe 2 and blast pipe 3 at drying tower tower body 1 top, are provided with burner 4 in the middle of the said blast pipe 3; The gas inlet pipe 5 of burner 4 is I-shaped, and its upper surface offers a plurality of injector heads 6, and the outward flange of I-shaped gas inlet pipe is provided with protective cover 7, and protective cover 7 upwards and is outwards expanded by the outward flange of I-shaped gas inlet pipe.Air inlet pipe logical combustion gas be the natural gas of clean environment firendly.Also comprise air intake filter 8 that is arranged on burner 4 air intake fronts and the flame-retardant device 9 that is arranged on burner 4 back in the blast pipe 3.Flame-retardant device 9 can be formed the twice protection network by the two net sheets in front and back, prevents inflammable or burning particles entering drying tower.
During use; Extraneous cold wind process air intake filter is to air intake blower fan; Air quantity per hour can reach 43000 cubes; Then enter into neat gas burner; Burner is heated to 180 degrees centigrade-220 degrees centigrade to the wind that newly advances through gas-firing;, flame-retardant device enters into spray drying tower after removing Mars; Because the hot blast temperature that gets in the tower improves; Powder material gets into drying tower material inlet end after can being forced into the 180-220 handkerchief; Spray by the nozzle on the drying tower arrival end again; Nozzle quantity can strengthen, and has improved the spraying ability, has improved the efficient of dry work.
The present invention uses the burner that is arranged in the blast pipe instead directly to air heat, and is simple in structure, need not too much auxiliary device, and the heat energy utilization rate is high; Burner is arranged into " worker " font, and flame can not disturb each other, forms an even temperature field in this heating place, makes cold air can obtain evenly, fully heat; It is convenient that combustion gas adds thermal control, and it is very high that heating-up temperature can reach, and can realize superhigh temperature, Fast Heating to material, to some food such as vegetable fat powder, also can better keep its nutrition and local flavor.
In addition; It all is clean before burner, setting up the new wind that the air intake filter guaranteed to get into burner, flame-retardant device is set behind burner can prevents inflammablely or burning particles gets into drying tower, and this not only is beneficial to safety in production; As far as food production, also guaranteed the health and the quality of food.
