Description

TECHNICAL FIELD

[0001] The utility model belongs to air purification technical field, concretely relates to an oil bath type air purification equipment. BACKGROUND

[0002] At present, in flour, cement production and other places, under the high dust concentration condition in air, the general dust removal device is mostly silk screen type secondary dust removal, or paper and fiber material filtration. The silk screen type secondary dust removal has small dust collection area, can only filter larger dust, causing fine dust to return to air again. The paper and fiber material filtration is easy to be blocked by dust particle accumulation, especially flour particles and cement particles are easy to bond and agglomerate, difficult to clean, and need to be replaced frequently, increasing the labor intensity of workers.

[0003] In view of the defects of the above dry dust removal equipment, the related working condition environment has begun to use pulse type filter bag air filter. Through the pulse pump or pulse valve, the filter bag is instantaneously expanded and contracted by inputting instantaneous impact airflow, the dust accumulated on the filter bag is shaken off, the blockage and bonding are avoided, and the automatic dust cleaning is realized. But the pulse pump or pulse valve has complex structure, poor dust removal, and also has blockage and bonding problems, so the maintenance is also frequent. For cement, flour and other sticky dust particles, once wet, they will bond the filter core and filter screen, resulting in automatic dust cleaning failure.

[0004] The oil bath type air filter uses oil bath air. The oil bath type air filter generally sucks air from a tangential direction into a circular cylinder through an external fan, uses the circular cylinder to make the air rotate at high speed, and separates dust particles in the airflow by centrifugal force and throws them to the cylinder wall. Then the airflow sweeps over the oil surface, the oil surface produces fluctuations, generates splashes, forms oil mist, and the oil mist is rotated and thrown to the cylinder wall by the airflow, adheres to the inner cylinder wall to form an oil film, and the dust particles in the airflow are captured by the oil film. The oil film flows back along the wall to form an oil curtain, which washes the dust captured by the oil film on the cylinder wall to the bottom of the cylinder and generates a new oil film. The air is subjected to an oil bath, and part of the dust particles are captured; the separated airflow passes through the filter element to remove the remaining dust particles and oil droplets, thereby achieving the purpose of filtering clean air. The dust particles remaining in the separated airflow have been fully contacted with the oil mist to form an oil film, which loses adhesion and avoids adhesion to the filter element, so that the dust particles cannot be agglomerated again. Although the oil bath can prevent the dust particles from adhering to the filter element, excessive splashes gathered on the filter element will cause the filter element to be blocked, so the filter element of the oil bath type air filter generally adopts a steel wire screen structure, which uses the reverse osmosis function of the steel wire screen to reverse osmosis excessive oil collection and avoid blocking the filter element. During the filtering process of the steel wire screen, too little oil mist is generated, the oil bath effect is poor, and the filtering efficiency is reduced; the filtering efficiency and oil consumption are difficult to balance, and the filter cannot be automatically cleaned, so manual maintenance is frequent; if a pulse pump or a pulse valve is used, the generated pulse wave will splash oil, causing excessive oil mist, which will exceed the reverse osmosis capacity of the steel wire screen, block the filter element, increase the oil mist leakage, increase the oil consumption, and even cause secondary pollution.
