In the past, the medium speed wheel type coal mill simply mixes after raw coal bin or belt material loading when mixing the material, and the coal drop pipe is as the only material import of medium speed coal mill, and the particulate material gets into the part of milling from the coal drop pipe, extrudes and grinds, and the final powder material of crushing.
The particle size of the blended burned material is small, some special blends with smaller particle size can be directly blown into a gasification furnace or a boiler for combustion or reaction without being milled by a milling area of a coal mill, if the fine particle blends without milling fall into the milling area of the coal mill along with raw coal, the blends without milling are secondarily milled, and the energy consumption of the coal mill is wasted.
The particle size of the powder coke blended and burned in the gasification project is smaller, and the powder coke is mainly distributed as follows: 0-20 μm accounts for 2.6%;20-50 μm accounts for 7.91%;50-90 μm accounts for 9.84%;90-120 μm accounts for 7.58%;120-220 μm accounts for 34.41%;220-710 μm accounts for 38.2%. About 30% of the particles are not required to be milled, and the particles with smaller particle size can be directly fed into the gasification furnace.
In addition, an inclined tee joint is added on a coal dropping pipeline between the coal mill and the coal feeder, and the pulverized coal enters a milling area of the coal mill together after being mixed with the raw coal through the tee joint, so that the mixing mode can also cause secondary milling of tiny mixture particles.
Disclosure of Invention
In view of the above, the utility model provides a pulverized coal separator for blending and burning pulverized coal in a pulverizing system of a gasification project, which mainly aims to solve the problem that the blend with smaller particles is excessively milled and energy consumption is wasted.
In order to achieve the above purpose, the present utility model mainly provides the following technical solutions:
the embodiment of the utility model provides a pulverized coal separator for blending and burning pulverized coal in a pulverizing system of a gasification project. It comprises the following steps:
a separator;
the raw coal falling pipeline is arranged in the center of the separator and is communicated with the separator;
a pair of coke breeze feeding devices; the two sides of the separator are respectively connected with the separator;
and the powder outlet pipeline is connected with the raw coal dropping pipeline.
As described above, the separator includes a first separator assembly, a cover plate connected to the first separator assembly, a blade connected to the cover plate, and a second separator assembly connected to the cover plate, where the pair of coke breeze feeding devices are respectively disposed on two sides of the cover plate and welded to the cover plate, and the pair of coke breeze feeding devices are both connected to the second separator assembly.
As previously described, the pair of coke breeze feed devices each include a coke breeze feed tube welded to the cover plate and connected to the second separator assembly and a pneumatic isolation gate mounted to the coke breeze feed tube via a flanged connection.
By means of the technical scheme, the pulverized coal separator for blending and burning pulverized coal, which is applicable to a pulverizing system of a gasification project, has at least the following advantages:
according to the pulverized coal separator for blending and burning pulverized coal, disclosed by the utility model, a raw coal dropping pipeline and a pulverized coal feeding device are separately arranged, a raw coal dropping pipe is arranged at the center of the separator, pulverized coal enters a first separator assembly area through a pulverized coal feeding pipe, pulverized coal blending with smaller particle size is separated and filtered for one time through a separation area of the separator, and filtered pulverized coal is returned to a grinding area of a coal mill through a powder return cone for grinding, so that excessive grinding of qualified particles is avoided, energy is saved, and consumption is reduced.
