Smoke exhaust pipe capable of reducing grease adhesion on inner wall

Abstract

The invention provides a smoke exhaust pipe capable of reducing grease adhesion on the inner wall. An ultraviolet lamp tube is coaxially arranged in the center of the smoke exhaust pipe, a plurality of partition plates are arranged between the ultraviolet lamp tube and the inner wall of the smoke exhaust pipe, two sides of each partition plate are connected with the ultraviolet lamp tube and the inner wall of the smoke exhaust pipe in a sealing manner so as to divide an air duct of the smoke exhaust pipe into a plurality of independent air ducts, and each partition plate is a spiral partition plate which spirally ascends around the ultraviolet lamp tube; and a plurality of oil collecting fins are arranged on the inner wall of the smoke exhaust pipe in each independent air duct, the oil collecting fins are bent and spirally distributed on the inner wall of the smoke exhaust pipe, and an oil exhaust pipe is connected to the bottom of the smoke exhaust pipe. According to the smoke exhaust pipe, by adopting the mode of combining the spiral separation sheets and ultraviolet rays, the content of grease in smoke discharged from a kitchen is reduced, attachment of grease in the air ducts is reduced, and corrosion of the air ducts is reduced; and moreover, the oil collecting fins are arranged in the air ducts, so that the grease in the spiral independent air ducts can be well collected on the inner side of an opening and falls to the bottom of the smoke exhaust pipe under the action of gravity, and cleaning is facilitated.

Description

technical field [0001] The invention relates to the smoke exhaust of pipes, in particular to a smoke exhaust pipe which can reduce the adhesion of grease on the inner wall. Background technique [0002] Kitchen exhaust contains a lot of grease, which is easy to adhere to the inner wall of the exhaust pipe, reducing the efficiency of smoke exhaust, increasing the corrosion of the air duct, and increasing the workload of cleaning. At present, there are usually two methods for removing grease from kitchen exhaust fume: one is to use a gas collecting hood that has the function of removing grease (similar to a household range hood with a certain function of removing grease), and reduce the adhesion of oil fume to the air by accelerating the gas flow rate. The inner wall of the pipe; the other is to install a special degreasing device on the exhaust pipe, for example, by spraying high-temperature steam to clean the grease in the pipe. [0003] At present, both of these two scheme...
