Tail gas filter

Abstract

The invention discloses a tail gas filter, which includes a fixed drum, an outer layer porous air filter pipe, a middle layer porous air filter pipe, an inner layer porous air filter pipe, and two air screens; the outer layer porous air filter pipe, the middle layer porous air filter pipe, and the inner layer porous air filter pipe are arranged inside the fixed drum; the tail end of the outer layer porous air filter pipe is provided with the two air screens; the air screens are fixed at the tail end of the fixed drum, and the tail gas filter is arranged inside a tail gas exhaust pipe. In the tail gas filter, a three-pipe two-screen structure is adopted, and a three-pipe two-screen filter is arranged in the air exhaust pipe of a car to play the roles of exhausting, dispersing and filtering layer by layer when the car is exhausting tail gases; when partial gases are exhausted, the gases are exhausted on the pipe wall of the fixed drum in the air exhaust pipe through filter holes in a filter drum to cool and form water; the water flows into the tail gas cooling water recycling device along the wall of the inner drum; meanwhile, the tail gas filter reduces the discharge of tail gases into the air, and can inject the recycled water into a water tank again for using; therefore, the tail gas filter has the effects of saving energies and protecting environment.

Description

technical field [0001] The invention relates to an exhaust gas filtering device installed in an automobile exhaust pipe. Background technique [0002] Now the car directly discharges the exhaust gas into the air through the exhaust pipe, and the exhaust gas flows directly to the land when the water formed in the exhaust pipe is cooled; while the uncooled water vapor in the exhaust gas is discharged into the atmosphere along with the exhaust gas, causing environmental pollution , and a waste of energy. For the above problems, there is no good solution at present. Therefore, based on the above problems, I have designed an exhaust filter installed inside the exhaust pipe and an exhaust pipe in which the filter is installed. Contents of the invention [0003] The purpose of the present invention is to provide an exhaust gas filtering device and an exhaust pipe equipped with an exhaust gas filter, so as to solve the problems of waste of condensed water in the exhaust pipe of ...
