Description

Technical Field

[0001] This utility model relates to the field of incinerators, and in particular to a humidifier for a hazardous waste incineration deacidification system. Background Technology

[0002] The flue gas generated from the incineration of hazardous waste in the incinerator is then cooled and cooled by waste heat before entering the dry deacidification tower for deacidification.

[0003] A dry desulfurization tower is a purification device mainly used to remove gaseous pollutants from flue gas. The reactant is lime powder, which is fed into the dry desulfurization tower by pneumatic conveying. The lime powder is stored in a lime silo and is supplied quantitatively by a feeder. A Roots blower sprays the lime powder into the dry desulfurization tower through pipelines. The lime powder reacts chemically with SO2, SO3, HCl, and HF in the flue gas to generate CaSO3, CaSO4, CaCl2, CaF2, etc., thereby removing some of the acidic gases from the flue gas.

[0004] Dry acid removal systems have low acid removal efficiency, approximately 30%-50%. This is because the gaseous pollutants in the flue gas come into contact with the reactant powder, requiring a long reaction time for complete reaction. Consequently, the reactant powder cannot effectively react with the gaseous pollutants, resulting in low reaction efficiency and therefore low acid removal efficiency.

[0005] Therefore, it is necessary to provide a humidifier for a hazardous waste incineration deacidification system to solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a schematic diagram of a preferred embodiment of a humidifier for a hazardous waste incineration deacidification system provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the shell.

[0025] The humidifier is used to humidify the lime and then transport the humidified lime to the homogenizer.

[0026] The shell 1 is also provided with an inlet for adding activated carbon powder or other auxiliary materials to remove dioxins, heavy metals or other pollutants from the flue gas.

[0027] The humidifying water in spray gun 3 can be sprayed evenly onto the surface of lime powder without using compressed air atomization.

[0028] The first delivery pipe 4 is a compressed air inlet, and the second delivery pipe 5 is a process water inlet.

[0029] Process water is atomized by compressed air and sprayed evenly onto the surface of lime powder to enhance the mixing effect.

[0030] Regulating valves and pressure meters are installed in the process water inlet pipe and compressed air pipe of the spray gun 3 to control the water inlet, air inlet and pressure.

[0032] The water inlet is located at the lower end of the lime feed inlet, and a spray gun is fixedly installed inside to spray the process water evenly on the surface of the lime powder.
