Embodiment

[0019] Such as Figures 1 to 3 As shown, a spray drying tower includes a drying tower body 1 and a feed pipe 2 and an air inlet pipe 3 whose outlet is arranged on the top of the drying tower body 1, and a burner 4 is arranged in the middle of the air inlet pipe 3; The gas inlet pipe 5 of the device 4 is I-shaped, and its upper surface is provided with a plurality of injection nozzles 6, and the outer edge of the I-shaped gas inlet pipe is provided with a protective cover 7, and the protective cover 7 is upward and downward from the outer edge of the I-shaped gas inlet pipe. Expand outward. The gas passed through the intake pipe is clean and environment-friendly natural gas. The air inlet pipe 3 also includes an air inlet filter 8 arranged in front of the air inlet end of the burner 4 and a flame arrester 9 arranged behind the burner 4 . Flame retardant 9 can be made up of two protective nets by front and back two net sheets, prevents that combustible or combustion particle e...

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 [0001] The invention relates to a novel burner and a spray drying tower using the burner. Background technique [0002] For non-dairy creamer or milk powder such as coffee, direct hot air drying can only dry the surface, and the inside of the powder is very easy to agglomerate. Spray drying is a method of systematic technology applied to material drying. The thinner material is sprayed in the drying tower After melting, in the contact with the hot air, the water vaporizes quickly to obtain a dry product. This method can directly dry the solution and emulsion into powder or granular products, and can save evaporation, crushing and other processes. [0003] The hot air used in the spray drying tower is currently obtained by exchanging heat between cold air and steam through plate heat exchangers, etc. The boiler can only heat the air indirectly, resulting in a lot of energy waste, too many auxiliary equipment, complicated process, etc. shortcoming. Boilers ar...
