Problems solved by technology

[0002] During the operation of the steam boiler in a thermal power plant, when there is a scale layer on the water-cooled wall tube (the scale layer is mainly iron-containing oxides), due to the poor heat transfer effect of the scale layer, the heat load of the water-cooled wall tube increases. The deposition rate of copper in the furnace tube will be accelerated here, which will easily cause the water-cooled wall tube to burst. Therefore, some reagents for treating copper ions in the water can be added to the water to produce precipitation, but the resulting precipitation will affect the water pipeline. Cause blockage, need to filter the generated precipitate

Abstract

The invention discloses a boiler drum protection auxiliary device which comprises a first supporting piece, a connecting pipe is fixedly connected to the first supporting piece, an auxiliary assembly is arranged in the connecting pipe and comprises a filter screen, the filter screen is arranged in a funnel shape, a containing net is arranged at the bottom of the filter screen, and the containing net is arranged in a multi-layer mode. A second supporting piece is fixedly connected to the side, away from the filter screen, of the containing screen and inserted into the connecting pipe. According to the water-cooled wall pipe, the containing nets are arranged to be multiple layers, so that water in the water-cooled wall pipe is conveniently filtered for multiple times, copper compound precipitates generated in the water-cooled wall pipe are collected, and the problems of pipe explosion and abnormal shutdown after a water conveying pipeline is blocked by the generated precipitates are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of thermal power generation boilers, and in particular relates to a boiler steam drum protection auxiliary device. Background technique [0002] During the operation of the steam boiler of the thermal power plant, when there is a scale layer on the water-cooled wall tube (the scale layer is mainly iron-containing oxides), due to the poor heat transfer effect of the scale layer, the heat load of the water-cooled wall tube increases. The deposition rate of copper in the furnace tube will be accelerated, which will easily lead to the tube burst of the water-cooled wall tube. Therefore, it can be used to add some reagents for treating copper ions in the water, which will cause precipitation, but the resulting precipitation will affect the water pipeline. Clogging is caused, and the resulting precipitate needs to be filtered. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide ...
