Embodiment 1

[0019] An environmental protection process for treating boiler flue gas, which includes the following steps:

[0020] First, the boiler flue gas is sprayed with water to cool it so that the flue gas temperature is controlled within 100 ℃, then the large particles of dust are removed through the dust collector, and then it enters the reactor equipped with adsorbent for desulfurization, denitrification and dust removal. After the treatment, discharge;

[0021] The adsorbent is prepared according to the following process:

[0022] Step 1) Preparation of material A: Sepiolite is added to the crusher for crushing, then mixed with fly ash, calcium fluoride, high alumina bauxite, and then ground to obtain powder with a particle size of 100 mesh, which is the material A; Among them, the mass ratio of sepiolite, fly ash, calcium fluoride and high alumina bauxite is 7:5:4:2;

[0023] Step 2) Preparation of material B: Put the sorghum stalks into a pulverizer to pulverize, then pass a 100-mesh ...

Abstract

The invention belongs to the technical field of flue gas treatment, and discloses an environmental protection process for treating boiler flue gas. The environmental protection process comprises the following steps: first spraying water to the boiler flue gas to lower the temperature, controlling the temperature of the flue gas at 100 DEG C or below, removing large-particle dust by virtue of a dust collector, then placing the flue gas into a reactor with adsorbent to perform the desulphurization, denitrification and dust removal treatment, and finally discharging the flue gas after being treated. Water spraying, the dust collector and the adsorbent are adopted to carry out the desulphurization, denitrification and dust removal treatment on the flue gas, so that the environmental protection process is good in effect, environment-friendly and pollution-free.

Description

Technical field [0001] The invention belongs to the technical field of flue gas treatment, and specifically relates to an environmental protection process for treating boiler flue gas. Background technique [0002] Boiler flue gas is a mixture of gas and soot, which is the main cause of air pollution in residential areas. The composition of the flue gas is very complex. The gas includes water vapor, sulfur dioxide, hydrocarbons, and nitrogen oxides. The flue dust includes fuel ash, coal particles, oil droplets, and high-temperature cracking products. Therefore, the pollution of flue gas to the environment is a compound pollution of multiple poisons. The hazard of smoke and dust to the human body is related to the size of the particles. Most of the hazards to the human body are the airborne dust with a diameter of less than 10 microns, and the airborne dust with a diameter of 1-2.5 microns is the most harmful. [0003] my country is a big country in the production and use of indus...
