A noise reduction device and method for dry desulfurization and denitrification

Abstract

The invention discloses a sound-absorbing device and method for dry-process desulfurization and denitrification, which belong to the technical field of dry-process desulfurization and denitrification, and comprise a driving mechanism and an air-circulating mechanism. The interior of the furnace is communicated with the feed port on the side wall of the furnace, and the instantaneous shunting of organic calcium is realized through the ring air mechanism, which reduces the noise caused by the instantaneous expansion of organic calcium. , increase the flow path of organic calcium, reduce the speed of organic calcium when it first enters the outer casing, and avoid the noise caused by the rapid expansion of organic calcium; through the linkage between the pressure sensor and the controller, the internal drive motor is automatically turned on, effectively avoiding The time difference during manual operation can prevent the noise caused by the direct injection of organic calcium in time, and realize the split flow of organic calcium at the moment of injection through the mechanical structure. The structure is simple, the cost is low, and it is easy to use.

Description

technical field [0001] The invention relates to the technical field of dry desulfurization and denitrification, in particular to a sound-absorbing device and method for dry desulfurization and denitrification. Background technique [0002] In-furnace organic calcium desulfurization and denitrification technology is a kind of dry desulfurization and denitrification technology. The specific process is to generate organic calcium through the reaction of organic oil generated by high-temperature pyrolysis of garbage waste with calcium-based compounds, and then spray organic calcium into the furnace for combustion. Instantaneous expansion, decomposition and combustion occur under high temperature conditions, so as to obtain high flue gas desulfurization and denitrification efficiency, but in the process of organic calcium desulfurization and denitrification in the furnace, the instantaneous speed of the organic calcium injected by the spray gun into the furnace is very fast, The ...

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of sound-absorbing device and method that can effectively eliminate noise, is simple in structure, low in cost, and is easy to use, so as to solve the problem of organic calcium sprayed into the furnace by the spray gun proposed in the above-mentioned background technology. The instantaneous speed is very fast, and when it is in contact with the high temperature in the furnace, it will cause a large impact on the furnace wall when it expands instantaneously, and it will cause a loud noise. With the continuous injection of organic calcium, the furnace will continue to emit noise, which will seriously affect the work. personnel health issues
