| titleOfInvention | Semi-dry scrubber |
| abstract | The present invention relates to a semi-dry scrubber that is installed to remove harmful gases generated during combustion in an incinerator.n n n Conventional semi-dry scrubbers are liquid particulate lime (Ca (OH) ₂), which is a neutralizing agent, and air and water in the form of fine particles having a diameter of several tens to hundreds of micrometers through a nozzle (2) installed in the main body (1) of the semi-dry scrubber. The harmful gas (hydrogen chloride (Hcl), sulfur oxide (SO₂), hydrogen fluoride (HF), volatile organic compounds (VOC), etc.) contained in the combustion gas introduced through the gas inlet (3) by spraying, It is classified into a solid product, which is a reaction product generated by the neutralization reaction of adsorption, and gases such as water vapor and falls to the lower part of the main body 1. Most of the dust dropped to the bottom is collected by the dust hopper (4) is collected in the dust box (not shown) through the lower dust outlet (5), and gas such as water vapor is installed on the side of the dust hopper (4) It has a structure to be discharged through the outlet (7).n n n However, the semi-dry scrubber is a device that can help the mixing of the liquid lime and the harmful gas contained in the air, water and combustion gas sprayed in the form of particles having a diameter of several tens to hundreds of micrometers through a nozzle installed in the main body It is not installed, but only natural mixing inside the main body, so it is not possible to achieve a complete mixing of harmful gases (hydrogen chloride (Hcl), sulfur oxides (SO₂), hydrogen fluoride (HF), volatile organic compounds (VOC), etc.) There was a problem in that the neutralization efficiency of the remarkably decreased to increase a large amount of dust load.n n n In addition, the liquid lime and the air sprayed through the nozzles accumulate on the inner wall of the main body of the scrubber, there was a problem that the treatment efficiency of harmful gases is reduced.n n n Therefore, the present invention is harmful to the particulates of the neutralizer (liquid lime) having a diameter of several tens to hundreds of micrometers sprayed through the spray nozzle on the top of the scrubber body and the combustion gas introduced through the air, water and gas inlet. By installing a large number of rotary fans to facilitate the mixing of gases (hydrogen chloride, sulfur oxides, volatile organic compounds, etc.), neutralize the liquid lime, which is a neutralizing agent, and artificially mix air, water, and harmful gases with a rotary fan. In addition to reducing the amount of dust load by improving the efficiency of the improved efficiency of the harmful gas. |
