Device for preventing dust agglomeration in chimney based on airflow transformation

Abstract

The invention discloses a device for preventing dust agglomeration in a chimney based on airflow transformation. The device comprises a chimney body, wherein two symmetrical dust removal rings are inoverlap joint to the inner wall of the chimney body; dust removal blocks are fixed on the side, close to the chimney body, of the dust removal rings; fixed rods are fixed at the lower ends of the dustremoval rings, and tension springs are elastically connected to the middle of the fixed rods. By cooperative utilization of the dust removal rings, the dust removal blocks, telescopic rods, dust removal brushes and airflow plates, the principle that airflow in a furnace moves upwards from the inside of the chimney body can be effectively utilized, and the airflow plates can be effectively drivento rotate, so that the dust removal rings and the dust removal blocks scrape off dust blocks agglomerated in the chimney body; the device has the advantage of automatically removing dust on the innerwall of the chimney body in the process of flue gas emission, the working process is simplified, manual removal is not needed, labor is saved, body health of workers is guaranteed, and the device is convenient to use.

Description

technical field [0001] The invention relates to the technical field of resources and the environment, in particular to a device for preventing dust accumulation inside a chimney based on airflow transformation. Background technique [0002] The environmental globalization of the world today and the national environmental protection policy implement "energy saving, emission reduction, and total control", but the traditional water film dust collector, water bath dust collector, and cyclone dust collector are difficult to adapt to today's environmental protection and emission reduction requirements. After comprehensive consideration of the information provided by your company and inspection of site conditions, our technical staff compiled the design plan of the kiln flue gas dedusting and desulfurization technology, so that the flue gas at the tail of the kiln will be polluted by soot and SO2 after being treated by dust removal and desulfurization technical equipment All substa...

Problems solved by technology

[0003] Although the flue gas desulfurization in the kiln has achieved some results, there are still some problems that have not been solved. The evaporated water vapor will adhere to the dust in the chimney or other burned organic matter. After that, the water vapor will increase in liquefaction weight when it is cooled, and it will easily adhere to the inner wall of the chimney during the falling process, forming a thick layer of ash. If it is not cleaned for a long time, it may affect the smoke and sulfur removal of the chimney, which will pollute the environment and be inconvenient to use. Usually, it is cleaned regularly by the staff. However, due to the huge volume of the chimney itself, the staff will not In the process, if the protective measures are not in place, it may threaten the personal health of the staff. At the same time, the staff may inhale harmful gases during the cleaning process, which is inconvenient to use.
