Air filter based on centrifugal principle

Abstract

The invention discloses an air filter based on the centrifugal principle. The air filter comprises a centrifugal dust removing chamber and a first filtering chamber, wherein the centrifugal dust removing chamber comprises an outer chamber and an inner chamber arranged in the outer chamber, and a first air inlet is formed in the outer chamber; and the bottom of the outer cavity is provided with an air outlet pipe which communicates with the inner cavity, and the air outlet pipe is arranged along the side wall of the inner cavity in the tangential direction. According to the air filter, water in a spraying disc is sprayed on the inner wall of the inner cavity to form a water film and adhere to dust thrown on the inner wall of the inner cavity, so that the purpose of pre-dedusting is achieved; and meanwhile, in the falling process of the water along the inner wall of the inner cavity, the air can play an air-cooling role, and then the water temperature is lowered.

Description

technical field [0001] The invention relates to the technical field of engine air filters, in particular to an air filter based on the centrifugal principle. Background technique [0002] In order for the engine to function properly, a large amount of pure air must be drawn in. If the substances harmful to the engine in the air (dust, colloid, aluminum oxide, iron oxide, etc.) are inhaled, the cylinder and piston components will increase the burden, causing abnormal wear, and even mixing with the engine oil, causing greater wear , resulting in deterioration of engine performance and shortened life. The role of the car air filter is to provide clean air for the engine to prevent the engine from inhaling air with impurity particles and causing wear and tear. [0003] When the existing air filter is in use, the filtering effect is poor, and the dust accumulation speed is fast, which leads to the deterioration of the air permeability. The air permeability can only be guarantee...

Problems solved by technology

However, with the use of the engine, the temperature of the cooling water in the water tank will gradually increase, resulting in the gradual deterioration of the heat dissipation effect of the engine. If the temperature is too high, the expansion of the engine parts will reduce the matching clearance of various parts. On the other hand, if the temperature is too high The viscosity of the oil decreases, in which case the wear of the components increases
