Turbulent and boiling combined-circulation fluidized bed refuse incinerator

Abstract

The invention provides a turbulent and boiling combined-circulation fluidized bed refuse incinerator, belonging to the garbage disposer field. The present circulation fluidized bed refuse incinerator has unstable bed temperature, inadequate burning and high energy consumption. The turbulent and boiling combined-circulation fluidized bed refuse incinerator comprises a hearth and a cyclone separator, a boiling chamber is arranged at the lower part of the hearth, a refuse inlet is opened in the middle of the hearth, the upper part of the hearth is communicated with the cyclone separator, the lower part of the cyclone separator is communicated with the hearth by a feedback device, the turbulent and boiling combined-circulation fluidized bed refuse incinerator is characterized in that a turbulent chamber capable of slantly moving and transferring the refuse is arranged under the refuse inlet. The turbulent and boiling combined-circulation fluidized bed refuse incinerator provided by the invention solves the problems of inadequate burning and high coal doping, saves the energy and improves the treating capacity of single refuse incinerator per day.

Description

【Technical field】 [0001] The invention relates to a turbulent compound circulating fluidized bed garbage incinerator, which belongs to the field of garbage treatment equipment. 【Background technique】 [0002] Nowadays, my country's garbage generally has characteristics such as low degree of garbage classification, complex composition, high water content, and low calorific value, which are not conducive to combustion. In the traditional circulating fluidized bed garbage incinerator, the garbage is sent into the furnace by the feeding device. Since the traditional furnaces are all vertical furnaces, the garbage falls directly under the action of gravity, so that various complex components cannot be burned out in a short time after the garbage enters the incinerator, and its moisture content is high, so it needs to absorb a large amount of heat after entering the incinerator. to evaporate the water in it, which makes the combustion stability not guaranteed, and the operation p...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the disadvantages of unstable temperature in the incinerator, insufficient combustion, high proportion of coal blending, and large energy consumption in the prior art, the present invention provides a new type of turbulent compound circulating fluidized bed garbage incinerator. chamber, so that the garbage is fully dried and pyrolyzed before entering the boiling chamber, so that the garbage can be fully burned, effectively reducing the blending ratio of coal, and effectively reducing high-temperature slagging and wear and corrosion of the tail heating surface
