The invention discloses an air filtering device for environmental protection engineering, and relates to the technical field of environmental protection engineering. The problem that a filter screen is blocked is solved. The air filtering device specifically comprises a base, a box body is fixed to the outer wall of the top of the base through bolts, a filtering mechanism and a pulse type power mechanism are sequentially arranged on the outer wall of the top of the base, the outer wall of the top of the base is movably connected with a humidifying mechanism through a first sliding groove, andthe pulse type power mechanism comprises a cylinder body and a piston; the cylinder body is fixed to the inner wall of the box body through bolts, the piston is connected to the inner wall of the cylinder body in a sealed and sliding mode, and a connecting rod is rotatably connected to the outer wall of the bottom of the piston. A power source is arranged to be pulse type air suction and exhaust,during air suction, a filter element is elastically deformed in the airflow flowing direction due to airflow resistance, in the non-air-suction state, the airflow resistance disappears, the filter element rebounds, at the moment, dirt adhering to the outer wall of the filter element can be bounced off, and thus the self-purification effect is achieved, and the filter element is prevented from being blocked.
Description
technical field [0001] The invention relates to the technical field of environmental protection engineering, in particular to an air filter device for environmental protection engineering. Background technique [0002] With the increasingly serious air pollution, air filter devices have become more and more important to life, medical care, production, etc. At present, the more popular air filter devices on the market use flat filter paper, and the air passes through the filter paper. Finally, the impurities such as dust and bacteria are separated from the pure air to achieve the effect of purification, but they all use fans as the power source of air flow, and when the fans are working, their power is constant, resulting in constant air intake speed, filtering The air flow pressure to which the paper is subjected is also constant. [0003] After retrieval, the Chinese Patent Publication No. CN106390656B discloses an air filter device, including: a housing; at least two filt...
