Problems solved by technology

[0006] At present, the common problems in the use of atomizing nozzles include large droplets and fouling at the nozzle, as follows: (1) Large droplets, small droplets sprayed from the spray gun (droplets with a diameter range of 50~100μm) There will be overlapping in the flue, and then large fog droplets (fog droplets with a diameter range of more than 100μm), this large fog droplets will combine with the fly ash in the flue to form ash particles that are difficult to evaporate, and these ash particles that are difficult to evaporate It will reduce the service life of the spray gun, and will cause corrosion to the flue and the electrostatic precipitator; (2) Scaling, there are some high concentrations of calcium and magnesium ions in the desulfurization wastewater, which is easy to scale, the nozzle goes deep into the flue, and the temperature in the flue Higher, and there is a large amount of fly ash, which is easy to scale, thereby reducing the service life of the spray gun

Embodiment 1

[0025] like Figure 2~3 shown (for demonstration purposes, image 3 The three-bladed impeller 208 is not shown in the figure), an improved atomizing spray gun, one end of the atomizing spray gun is a nozzle 201, and the other end is an inlet, the atomizing spray gun includes a liquid pipeline 202 for the circulation of desulfurization wastewater, and a sleeve The gas pipeline 203 located outside the liquid pipeline 202 is welded with three brackets 204 at an angle of 120° between the two to support and fix the two, and one end of the two is open to each other, and the other end of the two is open. Sealed with each other, the open end is the nozzle 201, and the sealed end is the inlet, the inlet includes a liquid inlet 205 and a gas inlet 206, the liquid inlet 205 is used for desulfurization waste water, the gas inlet 206 is used for cooling gas, and the liquid inlet 205 is opened On the wall of the other end of the liquid pipeline 202 , the gas inlet 206 is opened on the wall...

Embodiment 2

[0028]A flue evaporation system for desulfurization wastewater, including boilers, economizers, air preheaters, electric precipitators, desulfurization towers and several spray guns connected in sequence through the flue. The desulfurization waste water discharged from the desulfurization tower passes through several atomization After the spray gun is atomized, it is discharged back to the flue between the air preheater and the electrostatic precipitator to form a circulation to treat the desulfurization wastewater. The atomization spray gun is the atomization spray gun of Embodiment 1. This embodiment does not make improvements to other equipment of the desulfurization wastewater flue evaporation system, so it will not be repeated here.

Abstract

The invention discloses an improved atomizing spray gun and a flue evaporation system. The atomizing spray gun comprises a liquid pipeline for circulating desulfurization wastewater, and a gas pipeline which is arranged outside the liquid pipeline in a sleeving manner; cooling gas is introduced between the liquid pipeline and the gas pipeline; a structure for changing pipeline sectional area is arranged in the liquid pipeline, the structure for changing pipeline sectional area can change the sectional area of the liquid pipeline in a periodic mode; and compared with a conventional atomizing spray gun in the prior art, the atomizing spray gun has the beneficial effects that large fog drops are not prone to occurring, and scaling is not prone to occurring.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an improved atomizing spray gun and a flue evaporation system. Background technique [0002] In the 1970s, scholars at home and abroad proposed the idea of ​​"zero discharge" of desulfurization wastewater, which means that the power plant does not discharge any wastewater to external waters. Through desulfurization wastewater treatment technology, all the water leaving the power plant is evaporated to the atmosphere in the form of steam In or with a small amount of moisture contained in ash and slag. The desulfurization wastewater flue evaporation process is a kind of desulfurization wastewater treatment technology. After years of research, design and optimization, the desulfurization wastewater flue evaporation process has gradually moved towards practical application, and has been continuously improved, and has been industrialized in some power plants in my country...
