Anti-corrosion waste incineration boiler superheater system

Abstract

The invention relates to the technical field of waste incineration, in particular to an anti-corrosion waste incineration boiler superheater system which comprises a boiler body, a smoke outlet pipe fitting, a first blower device and superheater equipment, the first blower device and the superheater equipment are located on the smoke outlet pipe fitting, one end of the smoke outlet pipe fitting is communicated with a smoke outlet of the boiler body, and the other end of the smoke outlet pipe fitting is communicated with the superheater equipment. The first blowing device is arranged on the smoke outlet pipe fitting and comprises a first blower and a first blowing pipeline, the first blower is arranged on the smoke outlet pipe fitting, an air outlet of the first blower is communicated with the first blowing pipeline, and the first blowing pipeline is communicated with the smoke outlet pipe fitting. Low-temperature air is blown into the smoke outlet pipe fitting, so that the low-temperature air exchanges heat with high-temperature corrosive smoke generated by the boiler body to generate high-temperature air, direct heat exchange between the high-temperature corrosive smoke and superheater equipment is reduced, the problem of corrosion of the superheater equipment is fundamentally solved, and the working efficiency of the boiler body can be improved.

Description

technical field [0001] The invention relates to the field of waste incineration technology, in particular to an anti-corrosion superheater system of a waste incineration boiler. Background technique [0002] At present, with the increasing amount of urban domestic garbage, the garbage has brought more and more pressure to the city's green and environmental protection. In order to deal with urban waste, waste incineration is usually used, and a large amount of waste is put into a power generation boiler for combustion. In the process of burning garbage, a lot of heat will be generated. [0003] During the process of garbage incineration, the boiler flue gas produced contains a large amount of corrosive flue gas, which will cause serious high-temperature corrosion to the boiler superheater under high temperature conditions, resulting in low overall power generation efficiency of the system. [0004] In view of the above-mentioned related technologies, the inventor believes t...

Problems solved by technology

[0003] During the incineration process of garbage, the boiler flue gas produced contains a large amount of corrosive flue gas, which will cause serious high-temperature corrosion to the boiler superheater at high temperature, resulting in low overall power generation efficiency of the system

[0004] In view of the above-mentioned related technologies, the inventor believes that a large amount of high-temperature corrosive air will be generated during the incineration of garbage. After the high-temperature corrosive air is in direct contact with the high-temperature steam metal heat exchanger, it is easy to cause corrosion of the boiler superheater.
