Abstract

The invention discloses a ring-shaped edge part airflow totally enclosed type kitchen assistant smoke discharge system, which comprises a first static pressure case and a second static pressure case, wherein the first static pressure case and the second static pressure case are arranged symmetrically and parallelly and are communicated through a ventilating pipeline, the ventilating pipeline is connected with a fan, a first air blast channel and a third air blast channel are respectively arranged below the outer ring and the inner ring of a ring-shaped structure of the first static pressure case, and a second air blast channel and a fourth air blast channel are arranged above the outer ring and the inner ring of a ring-shaped structure of the second static pressure case. Due to the uniquedesign of the ring-shaped edge part airflow enclosed type kitchen assistant smoke discharge system, six groups of mutually colliding airflows are generated, and an air piston is pushed by virtue of the collision among the airflows, thus smoke gas attempting to overflow is returned to the action range of a smoke discharge hood to be sucked, air cleanness is ensured for operating personnel, and an relatively clean work environment is created for the region of kitchen working personnel.

Description

technical field

[0001] The invention relates to a kitchen smoke exhaust system, in particular to an auxiliary kitchen smoke exhaust system with ring-shaped side airflow fully enclosed. Background technique

[0002] The pollution of cooking smoke is very serious, and it is one of the important indoor air pollutants. The research on its health hazards has been paid more and more attention in recent years. The fuel generally used in the cooking process is coal gas, natural gas, liquefied petroleum gas, and coal. Their combustion process can produce various harmful gases, which are the main source of kitchen smoke. There are many kinds of edible oils for cooking food, such as: soybean oil, rapeseed oil, peanut oil, etc., which are thermally cracked and decomposed at 150-200°C. This produces large amounts of noxious fumes. Since the flue gas is at a higher temperature than the environment, its density will be lower than that of air. The low smoke density compared to the surrou...
