Shell-detachable large-inner-cavity smoke inlet device

Abstract

The invention discloses a large inner chamber flue gas intake device with a detachable shell, which comprises a shell with an opening A on one side and an air intake cover arranged at the opening of the shell A. For the fan on the A opening, the casing is provided with an exhaust port on the side away from the A opening; the casing is a pipe structure in the shape of a tapered column; the casing includes a main frame and a detachable shell, and the main frame is Conical column-shaped pipe structure, the side surface of the main frame is provided with an annular groove on the outside near the opening of A, and the annular groove is a mesh porous structure; the outer shell is a ring attached to the main frame The tapered column structure in the groove; the side curved surface of the main frame is provided with a ring-shaped inner concave baffle on the inner wall near the A opening; the fan is provided with a closed centrifugal impeller, and the closed centrifugal impeller on the side The annular air outlet corresponds to the annular inner concave baffle. The invention has a simple structure and is convenient for cleaning.

Description

technical field [0001] The invention relates to the field of oil fume treatment equipment, and specifically refers to a large inner cavity smoke gas intake device with a detachable shell. Background technique [0002] Kitchen fume is a large amount of thermal oxidation decomposition products produced by cooking oil and food under high temperature conditions. When cooking, the fat is heated. When the temperature reaches the smoking point of edible oil at 170°C, the blue smoke of initial decomposition appears. As the temperature continues to rise, the decomposition speed accelerates. It has a pungent smell, and the particle size of oil fume is 0.01-0.3 microns. The oil fume samples collected from households that often fry food were analyzed, and a total of more than 220 chemical substances were detected, including aldehydes, ketones, hydrocarbons, fatty acids, alcohols, aromatic compounds, esters, lactones, heterocyclic compounds, etc. . Known mutational carcinogens such as...
