Abstract

The invention relates to a muffle moving bed incineration device, which can solve the problems of local temperature overheating of incinerator which can cause overheating material, can strengthen the heating speed of incineration material, and can effectively utilize the discharged energy when burning fuel in the burning chamber. The invention utilizes the high-temperature flame and high-temperature smoke to indirectly heat the incinerator of moving bed; the high-temperature smoke can quickly enter high-velocity fluidized bed; the high-temperature gas can form gas-solid high-velocity fluidized mixing heating on the preheated material, therefore, the high-temperature gas and material can generate effective high-velocity heat and mass transfer; the material which has been heated to demanded temperature via the gas-solid separation of high-temperature gas-solid separator is fed into the incinerator of moving bed to be incinerated; the separated gas is used to preheat material; the hot material is fed into storehouse via the cooling discharge device; the average residence time of material in the incinerator of said muffle moving bed incinerator can be adjust between several minutes to hours, while the incinerator temperature is controlled between 500-1200Deg. C and the furnace temperature difference is controlled in í‚5Deg. C.

Description

technical field [0001] The invention relates to a flame-chambered moving bed calcination device, which relates to the technical field of calcination equipment. Background technique [0002] At present, the calcining equipment includes rotary kiln, multi-layer furnace, tunnel kiln and so on. For the calcination of powder materials, the heat transfer and mass transfer of the materials in the rotary kiln, multi-layer furnace, and tunnel kiln calciner are poor, and the material is heated slowly, resulting in high energy consumption and low production capacity of a single equipment. Contents of the invention [0003] The purpose of the present invention is to provide a flame-trap moving bed calcination device, which has the characteristics of rapid fluidization technology, such as fast heat transfer and mass transfer, uniform temperature in the furnace, and low energy consumption. It also has uniform calcination reaction time and can effectively avoid material burnt. [0004]...
