Car carbon tank with multi-cavity filter function

Abstract

The invention discloses a car carbon tank with a multi-cavity filter function. The tank comprises a tank body, four partition boards are fixedly mounted in the tank body, the interior of the tank bodyis sequentially divided into a purifying cavity, an active carbon cavity and a mixing cavity from bottom to top through the four partition boards, the side faces, close to the inner side wall of thetank body, of the partition boards are in clamped connection with ventilation pipes, the side faces, corresponding to the interior of the tank body, of the partition boards are fixedly provided with isolation net plates through fixed plates, when air enters an air circulation pipe through a fixed cylinder, under the effect of an air filter net in the fixed cylinder, dust in air can be filtered, dust stays on the surface of the air filter net, when the air flows in the air circulation pipe, due to the fact that the outer surface of the air circulation pipe is of a net-shaped honeycomb structure, the air can make contact with calcium chloride particles filled in the purifying cavity, the calcium chloride particles can absorb water in the air, the tank has the advantages of being good in dustremoval and humidity removal effect, simple in structure, convenient to use and the like, and the service life of the carbon tank can be greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of automobile carbon canisters, in particular to an automobile carbon canister with multi-chamber filters. Background technique [0002] The carbon canister is generally installed between the gasoline tank and the engine. Since gasoline is a volatile liquid, the fuel tank is often full of vapor at room temperature. The function of the fuel evaporative emission control system is to introduce the vapor into combustion and prevent it from volatilizing into the atmosphere. This process plays an important role in the activated carbon tank storage device. When the engine is turned off, gasoline vapor is mixed with fresh air in the tank and stored in the activated carbon tank. When the engine is started, it is installed in the activated carbon tank and the intake manifold. The electromagnetic valve between them is opened, and the gasoline vapor in the activated carbon tank is brought into the cylinder by the clean ...

Problems solved by technology

[0003] At present, because the carbon tank needs to inhale the outside air, the dust and moisture in the air will be brought in when the air is sucked in. When the dust and moisture accumulate inside the carbon tank for a long time, the service life of the carbon tank will be reduced.
