Description

Rotary type reactor soot blower

Technical Field

In the use process of the soot blower, the air pipe and the spray head are generally adopted to perform soot blowing in a matching way, namely in the use process, the air is blown into the air pipe through an air blowing device such as an air blower, and then the spray head connected with the air pipe performs soot blowing to the catalyst layer, so that soot blowing operation can be completed, and the purpose of preventing the catalyst from layering soot is achieved.

The reactor soot blower is generally fixedly connected with the reactor, i.e. after the soot blower is fixed with the reactor, the nozzle blows air against the catalyst layer to complete the soot blowing operation.

However, the spray head and the air pipe of the soot blower are fixed, so that only air can be blown in one direction, the soot blowing range is narrow, the incomplete soot blowing condition is easy to occur, or the condition of dust condensation exists, the soot blowing effect and the denitration efficiency are affected, and inconvenience is brought to a user.
