High-temperature cyclone separator anti-blocking apparatus and method thereof

Abstract

The invention discloses a high-temperature cyclone separator anti-blocking apparatus, which is arranged on a high-temperature cyclone separator ash storage bucket, the high-temperature cyclone separator anti-blocking apparatus comprises a heating device used for heating the ash storage bucket, a temperature monitoring apparatus used for real-time detecting the temperature of the ash storage bucket, and a dredge apparatus. The temperature monitoring device is capable of warning when the temperature of the ash storage bucket is lower than a set value. The dredge apparatus is capable of dredging a blocking part when the ash storage bucket is blocked by blowing air in the ash storage bucket. In addition, the invention also discloses an anti-blocking method for the high temperature cyclone separator, which is characterized in that the temperature change of the ash storage bucket is monitored so as to determine whether the ash storage bucket is full, blocked or requires to be heated. The anti-blocking apparatus and method have the advantages of simpleness and utility, and the blocking condition of the high temperature cyclone separator can be effectively prevented and controlled.

Description

technical field [0001] The invention relates to an anti-blocking device and method, in particular to an anti-blocking device and method for a high-temperature cyclone separator. Background technique [0002] China's coal reserves account for 12% of the world's coal resources, my country's low-rank coal reserves account for about 50% of coal reserves, and output accounts for 30% of the current total. In terms of geographical distribution, most of the reserves are concentrated in Inner Mongolia, Shaanxi, Xinjiang, Six provinces (regions) of Gansu, Shanxi and Ningxia. According to the age of coal formation in China, the Jurassic coal reserves are the largest, accounting for about 45% of the country's proven reserves. Except for a very small amount of anthracite coal formed in this era, most of the rest are lignite, long-flame coal, Low-rank coal such as non-caking coal and weakly caking coal. Lignite is the mineral coal with the lowest degree of coalification, a brown-black, d...

Problems solved by technology

[0007] However, when the existing high-temperature cyclone separator is put into operation or after it is out of operation, the shell temperature of the ash storage hopper is much lower than the inlet wind temperature of the cyclone separator, and the water vapor in the inlet wind encounters the low-temperature gas or The low-temperature shell will condense into water, and the dust agglomerated from the separation of water and cyclone will easily block the feeding port
