Abstract
The utility model relates to a burner, which comprises a fuel gas inlet pipe, and is characterized in that: the fuel gas inlet pipe is in an I shape, the upper surface of the I-shaped fuel gas inlet pipe is provided with a plurality of injector heads, and at least one part of the outer edge of the I-shaped fuel gas inlet pipe is provided with a protective cover. The utility model also relates to an atomizing drying tower utilizing the burner, which comprises a tower body and an air inlet pipe, and is characterized in that: the burner, an air inlet filter device and a flame retardant device are arranged inside the air inlet pipe, and the burner is arranged between the air inlet filter device and the flame retardant device inside the air inlet pipe. Due to the adoption of the atomizing drying tower which can directly heat the intake air, has rapid heating speed, utilizes environment-friendly energy and has high working efficiency, the heat utilization rate and the drying temperature of the atomizing drying tower can be greatly improved, and the ultra-high temperature and rapid heating of materials can be realized.
Description
Technical field
The utility model 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 be dried 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.
The utility model content
The purpose of the utility model 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, and a kind of direct heating air intake is provided, and 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 utility model 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.
The beneficial effect of the utility model is:
1. the burner of the utility model is set to I-shapedly, has taken into full account the air intake space of cold air, and has been 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 the utility model spray drying tower adopts the burner of direct gas-firing; Directly burning in airduct; The temperature of heating air intake can improve greatly, thereby has improved the powder material drying capacity, thereby compares 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.
Since the utility model spray drying tower at air intake arrival end mounting filtering device; The new wind that guarantees the entering burner all is clean; At the air intake end flame-retardant device is installed; Make Mars and flammable particle can't enter in the tower, the utility model spray drying tower can move safely and effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model burner;
Fig. 2 is the structural representation of the utility model spray drying tower;
Fig. 3 is the structural representation of the utility model spray drying tower blast pipe.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model 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 front and back two nets sheet, prevents inflammable or burning particles entering drying tower.
During use, to air intake blower fan, air quantity per hour can reach 43000 cubes to extraneous cold wind through the air intake filter; 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, after flame-retardant device is removed Mars, enters into spray drying tower; 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, and by the ejection of the nozzle on the drying tower arrival end, nozzle quantity can strengthen again; Improve the spraying ability, improved the efficient of dry work.
The utility model is used 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.
