Problems solved by technology

[0002] In the working process of thermal power plants, a large amount of coal needs to be burned. Since the coal contains more sulfides and nitrates after mining, the sulfides and nitrates flow with the exhaust gas during the coal combustion process. The existing The technology often uses a chimney at a high position to discharge the above-mentioned substances directly into the air, which increases the efficiency of pollutant diffusion to a large extent, affects the living environment of the surrounding people, and makes people's living conditions worse. Therefore, There is a need for a device that can desulfurize and denitrify these exhaust gases to avoid environmental pollution by exhaust gases
[0003] The current waste gas ecological and environmental protection treatment method in daily life takes too long in the process of waste gas desulfurization and denitrification, which reduces the efficiency of desulfurization and denitrification. With desulfurization and denitrification together, the desulfurization and denitrification solutions are mixed, and these mixed solutions are difficult to handle after desulfurization and denitrification are completed

Embodiment 1

[0035] see Figure 1-4 , the present invention provides a technical solution: an ecological and environmental protection treatment method for waste gas, comprising the following steps:

[0036] 1) Exhaust gas enters the pipe from the air inlet 1 and emerges from the exhaust holes at the bottom of the multiple exhaust pipes fixedly installed on the right side of the pipe 1. Many exhaust gas bubbles that emerge enter the desulfurization tank inside the desulfurization tank. in the solvent;

[0037] 2) The stirring motor drives the stirring blade on the stirring shaft to stir the desulfurization solvent inside the desulfurization tank, so as to speed up the contact between the exhaust gas bubbles and the desulfurization solvent to produce a reaction;

[0038]3) The desulfurization solvent extracted by the water pump 1 is sprayed from multiple spray heads and contacts the bubbles floating out of the desulfurization solvent in the air to further desulfurize. After the exhaust gas ...

Embodiment 2

[0045] In embodiment 1, the desulfurization solvent and the denitration solvent contain a desulfurization and denitration catalyst, and the preparation method of the desulfurization and denitration catalyst comprises the following steps:

[0046] S1 Add 10wt% activated carbon powder and 10wt% NY molecular sieve to 50-80um attapulgite clay powder, add acetic acid and stir, extrude, dry at 100°C for 3 hours, and bake at 350°C for 2 hours under nitrogen protection. Grinding to make a composite carrier;

[0047] S2 Send the composite carrier into the atmospheric pressure low temperature plasma device, make the composite carrier at the jet outlet of the atmospheric pressure low temperature plasma, pass the gas medium into the atmospheric pressure low temperature plasma device, apply the working voltage, form the plasma jet, and control the atmospheric pressure low temperature plasma The moving speed of the injection outlet of the plasma device is 10mm / s, so that the plasma jet is s...

Abstract

The invention relates to an ecological environment-friendly treatment method for waste gas. Waste gas enters a pipeline I from a gas inlet I, then the waste gas enters the desulfurization solvent in the desulfurization tank body from an exhaust hole formed in the bottom of the exhaust pipe I fixedly mounted on the right side of the pipeline I; the stirring motor drives the stirring shaft, and thestirring shaft drives the stirring blades to stir the desulfurization solvent so that the reaction is accelerated to perform desulfurization, and in the denitration tank body, the reaction is also accelerated to perform denitration, the reaction time of desulfurization and denitration is saved, and the desulfurization and denitration efficiency is improved.
