Description

Technical Field

[0001] The utility model relates to the technical field of decomposition furnace cleaning, in particular to a fluidizing device for a decomposition furnace. Background Art

[0002] The calciner is a new type of thermal equipment that simultaneously carries out fuel combustion, heat exchange and decomposition reaction. It has various types and forms. The working principle of the calciner is: preheated raw materials, a certain amount of fuel and an appropriate amount of hot gas are fed into the calciner at the same time. The raw materials are suspended or boiling in the furnace. Below 900℃, the fuel burns flamelessly, and the heat transfer and calcium carbonate decomposition process are completed at high speed. Solid, liquid or gaseous fuels can be used in the calciner.

[0003] Part of the existing decomposition furnace fuel uses domestic garbage as fuel, and domestic garbage as fuel will produce dioxins, NOx, SO2, CO, HCL and other substances and pollutants during combustion. The flue gas itself has a high viscosity, and the flue gas will adhere to the flue of the decomposition furnace as it flows, which will cause blockage for a long time, seriously affecting the flue gas flow and heat exchange efficiency. Therefore, it is necessary to clean the inner wall of the flue of the decomposition furnace. For example, a fluidizing device for a decomposition furnace provided by patent authorization number CN220567255U involves a device that can clean the flue gas attached to various parts of the decomposition furnace. It is mainly designed to solve the problem of dust substances generated when the decomposition furnace burns garbage and adheres to the decomposition furnace, causing blockage. It includes an energy storage tank body, with an air inlet pipe on the top of the energy storage tank body, and a valve installed on the air inlet pipe; the energy storage tank body is provided with a plurality of electromagnetic pulse valves, and the energy storage tank body is provided with a vent at the air inlet end corresponding to each electromagnetic pulse valve, and the air outlet end of each electromagnetic pulse valve is connected to a fluidizing pipeline, the front end of the fluidizing pipeline extends into the decomposition furnace, and the front end of each fluidizing pipeline located in the decomposition furnace has a plurality of jet ports. A protective shell is provided outside the energy storage tank body, and the air inlet pipes of each fluidizing pipeline and the top of the energy storage tank body extend from the protective shell, and a booster valve is installed on the air inlet pipe. The advantage is that it can effectively solve the problem of flue gas adhesion in the decomposition furnace and ensure the flue gas flow smoothly.

[0004] Based on the above search and in combination with the prior art, it is found that during the flue cleaning process, the impurities generated by combustion have strong adsorption and certain viscosity, so the flue cleaning method using airflow blowing is very likely to cause inadequate flue cleaning. Therefore, a fluidizing device for a decomposition furnace is proposed to improve the above problem. Utility Model Content
