Self-cleaning flue gas treatment pipeline with dynamic gas filter plate

Abstract

The invention discloses a self-cleaning flue gas treatment pipeline with a dynamic gas filter plate, and belongs to the field of flue gas treatment. The self-cleaning flue gas treatment pipeline withthe dynamic gas filter plate can generate a certain damping and force unloading effect on flue gas impact force through the arrangement of an inner variable layer, so that the dynamic gas filter plateis effectively protected from being damaged; meanwhile, a bidirectional movable through rod is arranged in the dynamic gas filter plate, and the repulsive force effect generated by a reverse thrust net on the bidirectional movable through rod is matched, so that when the flue gas inlet speed is continuously changed, the bidirectional movable through rod can continuously move left and right, and therefore the friction effect on the inner walls of the pores of the dynamic gas filter plate is achieved, the pores are continuously blocked while the flue gas is filtered, the blocking can be achieved without stopping the filtering process of the flue gas, and then the filtering efficiency of the flue gas is remarkably improved; and under the action of a fluctuation blocking layer, the blocking effect of the bidirectional movable through rod on the dynamic gas filter plate is more obvious.

Description

technical field [0001] The invention relates to the field of flue gas treatment, in particular to a self-cleaning flue gas treatment pipeline with a dynamic gas filter plate. Background technique [0002] Smoke is a mixture of gas and smoke and is the main cause of air pollution in residential areas. The composition of the flue gas is very complex. The gas includes water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides. The smoke includes fuel ash, coal particles, oil droplets, and pyrolysis products. Therefore, the pollution of flue gas to the environment is the compound pollution of various poisons. The harmfulness of smoke to the human body is related to the size of the particles. The most harmful to the human body is the floating dust with a diameter of less than 10um, especially the 1-2.5um floating dust is the most harmful. [0003] The suspended particles in the flue gas are also harmful. Due to the effect o...

Problems solved by technology

[0004] The existing filter plates used for flue gas filtration are prone to cracking or even cracking and disintegration after a period of use due to the long-term high temperature and the impact of flue gas, which not only has a low service life, but also causes damage to The filtering effect of flue gas drops sharply. At the same time, the existing filter plates need to stop the introduction of flue gas to clean and block after filtering for a period of time. Impact
