A high temperature cyclone separator anti-blocking device and method

Abstract

The invention discloses an anti-blocking device for a high-temperature cyclone separator, which is installed on an ash storage hopper of the high-temperature cyclone separator, and includes a heating device for heating the ash storage hopper, a temperature monitoring device for real-time detection of the temperature of the ash storage hopper, and unblocking devices. Wherein, the temperature monitoring device can issue a warning when the temperature of the ash storage hopper is lower than the set value. The dredging device can dredge the clogged part by blowing gas into the ash storage hopper when the ash storage hopper is clogged. In addition, the invention also discloses an anti-blocking method applied to a high-temperature cyclone separator, which mainly monitors the temperature change of the ash storage hopper to judge whether the ash storage hopper is full, blocked or needs to be heated. The anti-blocking device and method of the invention are simple and practical, and can effectively prevent the blockage of the high-temperature cyclone separator.

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
