Flue gas distributor of rotary spray deacidification reaction tower

Abstract

The invention provides a flue gas distributor of a rotary spray deacidification reaction tower, which comprises a flue shell, a flow guide plate assembly mounting flange, an atomizer supporting pipe, a flow guide plate assembly, a corner flow guide plate, an outlet shell, a rotary atomizer and an atomizing wheel, the flue shell is provided with a horizontal flue section and a vertical flue section, the flow guide plate assembly is installed on a flow guide plate assembly installation flange on the vertical flue section, a plurality of first flow guide channels are formed in the flow guide plate assembly, a second flow guide channel is formed in the corner flow guide plate, and the horizontal flue section is communicated with an inner cavity of the outlet shell through the first flow guide channels and the second flow guide channel. A double-layer rotational flow assembly is installed in the outlet shell, the atomizer supporting pipe is installed in the vertical flue section, the lower end of the atomizer supporting pipe extends into the center of the double-layer rotational flow assembly, a rotary atomizer and an atomizing wheel are installed, the flue gas distributor is convenient to disassemble and overhaul, the section of the gas flow channel is adjustable, and the flue gas distributor can adapt to changes of different flue gas amounts.

Description

【Technical field】 [0001] The invention relates to the technical field of semi-dry deacidification of domestic waste incineration flue gas, in particular to a flue gas distributor of a rotary spray deacidification reaction tower. 【Background technique】 [0002] Domestic waste incineration power plants need to purify and remove various pollutants in the flue gas and then discharge them up to standard. At present, the mainstream flue gas deacidification treatment method is the rotary spray semi-dry method, which mainly atomizes the deacidification agent into the deacidification reaction tower through a high-speed rotating centrifugal atomizer, and mixes with the flue gas that swirls into the reaction tower. The gas is fully mixed, contacted and reacted to achieve the maximum removal efficiency. Before the flue gas enters the reaction tower, it needs to be evenly distributed and guided to form a swirling airflow. The flue gas distributor arranged on the top of the reaction tow...

Problems solved by technology

Most of the existing reaction towers use volute-shaped flue gas distributors, which have complex structures, large volumes, and heavy weights. It is difficult to maintain or replace internal components after they are worn out.

In addition, the air flow channel of the existing distributor is fixed, and the cross section of the air flow channel is fixed after installation, so the range of adaptation to the change of flue gas volume is relatively narrow
