Abstract

The invention relates to an energy-saving efficient ammonia water evaporation device. The device comprises an insulating shell, wherein a heating medium inlet is formed in the lower portion of the insulating shell, a heating medium outlet is formed in the upper portion of the insulating shell, a spray gun spraying towards the interior of the insulating shell is arranged between the insulating shell and the heating medium outlet, the spray gun is an ammonia water solution single-fluid spray gun, and at least one group of enhanced heat exchange units are arranged above the spraying part of the spray gun and in the insulating shell, and the enhanced heat exchange units of multi-layer tubular structures arranged in a staggered manner. The low-pressure single-fluid spray gun is adopted, so thepower consumption of a feeding pump can be saved, and a large amount of compressed air can be saved; and the enhanced heat exchange units with the extremely large specific surface areas are arranged in the evaporation device, and low-pressure single-fluid ammonia water droplets are rapidly distributed on the staggered multi-layer tubular enhanced heat exchange units, so rapid evaporation is achieved, evaporation efficiency is high, crystallization is not generated, the length of the ammonia water evaporation device is greatly shortened, and manufacturing cost and field installation of the device are better facilitated.

Description

technical field [0001] The invention relates to an ammonia water evaporation device, in particular to an energy-saving and high-efficiency ammonia water evaporation device. Background technique [0002] At present, the ammonia water evaporator used in the domestic SCR denitrification project is composed of an insulating shell, a heating medium inlet temperature measurement unit, an ammonia water / compressed air dual-fluid spray gun, and a mixed medium outlet temperature measurement unit. The ammonia water and compressed air are sprayed through the dual-fluid spray gun Enter the ammonia water evaporator for atomization, mix with the heating medium, evaporate, and transport to the SCR reactor after evaporation. This type of ammonia water evaporator generally requires higher pressure on compressed air and ammonia water, which increases the power consumption required for spraying ammonia water. At the same time, this type of ammonia water evaporator needs more heat energy to heat...
