Chimney for dedusting and dehazing flue gas, and dedusting and dehazing technology thereof

Abstract

The invention relates to the technical field of flue gas dedusting and dehazing, and discloses a chimney for dedusting and dehazing flue gas, and a dedusting and dehazing technology thereof. The chimney for dedusting and dehazing flue gas comprises a chimney main body mainly composed of a collection chamber and a smoke discharge cylinder, the bottom of the smoke discharge cylinder is communicatedwith the gas outlet of a combustion furnace, and an atomizing nozzle is arranged in the smoke discharge cylinder; the collection chamber is connected with precipitation units through flow guiding tubes; and the atomizing nozzle is connected to the precipitation units through a conduit, and the conduit is provided with a pump. A spray solution is sprayed into the chimney through the atomizing nozzle to adsorb greenhouse gas, haze, smoke particles and other harmful substances in the flue gas, so the purposes of dedusting and dehazing are achieved; the adsorbed spray solution is precipitated andseparated by the precipitation units, and is properly adjusted and supplemented, so the circulation of the spray solution or the continuous spraying of the spray solution into the smoke discharge cylinder is realized, and the continuous dedusting and dehazing of the flue gas are achieved; and the dedusted and dehazed smoke is discharged to air, so the humidity of the air is increased, and the purposes of dedusting and dehazing the air are achieved.

Description

technical field [0001] The invention relates to the technical field of flue gas dust removal and haze reduction, in particular to a chimney for flue gas dust removal and haze reduction and a process for dust removal and haze reduction. Background technique [0002] With the rapid development of industry, a large amount of fossil fuels are burned, which emits a large amount of greenhouse gases and smog particles. Greenhouse gases affect the global climate, and smog particles are difficult to spread in calm weather, forming smog weather, which seriously affects people's production, life, and physical and mental health. At present, the control of greenhouse gas and smog particle emissions mainly depends on government regulation, enterprise shutdown and production, and improvement of dye combustion technology to reduce emissions. However, these measures have seriously affected the normal production and economic benefits of some enterprises. In addition, by washing the smog rece...

Problems solved by technology

At present, the control of greenhouse gas and smog particle emissions mainly depends on government regulation, enterprise shutdown and production, and improvement of dye combustion technology to reduce emissions. However, these measures have seriously affected the normal production and economic benefits of some enterprises.

In addition, by washing the smog receptors, such as artificial rainfall, natural rainfall to wash the outside atmosphere or windy weather to blow away the static and hazy weather, the consumption is large and the climate is suitable as a prerequisite, and the controllability is poor.

[0003] The flue gas is generally discharged through the chimney, which not only pollutes the environment, but also often carries greenhouse gases (CO 2 , SO 2 etc.), smog, smoke particles and other harmful substances, causing harm to the human body

Existing chimneys generally do not have the function of dust removal and haze reduction. How to design a chimney with dust removal and haze reduction has become a technical problem to be solved urgently by those skilled in the art
