Abstract

The invention discloses a desulfurization wastewater concentrated solution atomization device and an atomization anti-blocking method. The invention belongs to the field of environment-friendly devices. The device comprises a double-fluid spray gun, and the spray head of the double-fluid spray gun is positioned in an evaporation drying flue; two inlets of the double-fluid spray gun are respectively connected with an injection pump and a gas-water mixer; the injection pump is connected with a desulfurization wastewater concentrated solution storage tank; the gas-water mixer is connected with acompressed air storage tank and a humidifying water pump; a regulating valve is connected between the humidifying water pump and the gas-water mixer; compressed air can be humidified through the humidifying water pump, so that the moisture content of a desulfurization wastewater concentrated solution at the spray head is increased, the evaporation drying time of moisture is shortened, blockage ofthe gun body and the spray head due to too fast precipitation of gypsum suspended particles is avoided, and the problem that a spray gun is prone to blockage in the prior art is solved.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to an atomization device for concentrated liquid of desulfurization wastewater. Background technique [0002] The limestone-gypsum method is widely used in the desulfurization process of thermal power units in my country, and this process will produce a certain amount of desulfurization wastewater. At present, according to the characteristics of desulfurization wastewater, effective treatment methods include chemical methods of neutralization, flocculation, and precipitation, and zero-discharge methods of wastewater by concentration and evaporation. Among them, the concentrated wastewater in the wastewater zero discharge method has the characteristics of high salinity and contains suspended matter of older fine gypsum particles. After being atomized by a two-fluid spray gun, it is sprayed into the evaporation flue. After this process, the water in the mixture is sprayed at the n...
