Shell-detachable large-inner-cavity smoke inlet device

Abstract

The invention discloses a shell-detachable large-inner-cavity smoke inlet device comprising a shell and a gas inlet cover. An opening A is formed in one side of the shell. The gas inlet cover is arranged at the position of the opening A of the shell. A draught fan right opposite to the opening A is arranged in the shell. An exhaust port is formed in the side, away from the opening A, of the shell.The shell is of a pipeline structure shaped like a conical column. The shell comprises a main frame and a detachable shell. The main frame is of a pipeline structure shaped like a conical column. Anannular groove is formed in the outer side, close to the position of the opening A, of the side curved surface of the main frame and is of a mesh-shaped porous structure. The shell is of a conical column structure attached to the interior of the annular groove of the main frame. An annular inwards-indented surface baffle is arranged on the inner wall of the side, close to the opening A, of the side curved surface of the main frame. A closed centrifugal impeller is arranged on the draught fan. An annular air outlet in the side face of the closed centrifugal impeller corresponds to the annular inwards-indented surface baffle. The shell-detachable large-inner-cavity smoke inlet device is simple in structure and convenient to clean.

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...
