Embodiment 1
[0041] Such as figure 1 and figure 2 As shown, this embodiment provides a high-temperature gas-solid filtration and separation device used in the production of melamine. In the melamine production device, the temperature of the reaction gas from the catalytic reactor is about 400 ° C. The gas contains catalyst particles and by-product dust. Also contains flammable and toxic ammonia gas.
[0042] The high-temperature gas-solid filtration and separation device includes a filter body 1 with a clean gas outlet 2 on the top, an ash hopper 3 on the bottom, and a dust outlet 13 at the bottom of the ash hopper 3; the ash hopper 3 is arranged around the outside There is a loosening wind input device 15, and the loosening wind input device 15 includes 3 branch pipes evenly distributed around the ash hopper 3 and communicated with the ash hopper 3;
[0043] The flower plate 4 is erected on the upper part of the inner cavity of the filter body 1, and divides the filter body 1 into an u...
Embodiment 2
[0057] Such as figure 1 and figure 2 As shown, this embodiment provides a high-temperature gas-solid filtration and separation device used in the methanol-to-gasoline fluidized-bed process. In the methanol-to-gasoline fluidized-bed process, the temperature of the reaction product gas from the catalytic reactor is about 380°C, which is alkane , olefins, aromatics and other explosive gases, which contain catalyst dust particles, and there are carbon deposits and coking on the surface and interior of the catalyst particles.
[0058] The high-temperature gas-solid filtration and separation device is used in parallel with two separation devices. Each filter device includes a filter body 1 with a clean gas outlet 2 on the top, an ash hopper 3 on the bottom, and an ash hopper 3 at the bottom. Dust outlet 13; the outside of the ash hopper 3 is provided with a loose wind input device 15, and the loose wind input device 15 includes four branch pipes that are evenly distributed around ...
