Background

A chimney is a structure that provides ventilation for hot flue gases or fumes from a boiler, furnace, stove or fireplace. The chimney is usually vertical, or as close to vertical as possible, to ensure a smooth flow of gases, the intake air entering the so-called chimney combustion or chimney effect. The space within the chimney is called a flue. Chimneys may be found in buildings, steam locomotives and ships. The height of the stack affects its ability to transport flue gas to the outside environment through the stack effect. In addition, pollutant diffusion using a chimney in a high altitude area can reduce the influence on the surrounding environment. In the case of chemically aggressive output, a high enough stack may allow the chemicals in the air to partially or fully neutralize themselves before reaching ground level. The dispersion of the contaminants over a larger area may reduce their concentration and facilitate compliance with regulatory limits. The existing environment-friendly chimney can carry out denitration and desulfurization treatment on circulating gas, but has some defects in the use process of the environment-friendly chimney for desulfurization and denitration.

1. The environmental protection chimney can become the liquid of desulfurization and desulfurization usefulness foggy mostly when using, and the nitration thing and the sulphide in the gas carry out neutralization and deposit, reach the effect of denitration and desulfurization, but the environmental protection chimney that current desulfurization and denitration was used is lower to the atomizing rate of liquid, has influenced the speed of denitration and desulfurization, so can't satisfy the prior art needs.
