An energy-gathering device for the exhaust heat of flue gas in a commercial Chinese gas frying stove

Abstract

The invention discloses an energy accumulation device of a flue gas waste heat tail pan in a commercial Chinese meal gas cooking stove. The energy accumulation device is characterized by comprising a tail pan and a heat exchange energy accumulation body structure, wherein a plurality of inner holes are formed at the bottom of the inner side of the tail pan; the bottom of the outer side of the tail pan comprises a plurality of finned tubes, one ends of the finned tubes are respectively connected with the inner holes, and a plurality of closed hollow pipes are respectively arranged at the other ends of finned tubes; a plurality of fins are respectively arranged on the peripheral walls of the hollow pipes. According to the energy accumulation device, the emitted high temperature flue gas is ingeniously utilized, the heat of the high temperature flue gas is absorbed by the cold water in the pan again by an inner cavity of a hearth, and the flue gas circulates to the tail pan from the interior of the hearth, so that the cold water in the tail pan is pretreated into hot water, the flue gas emission temperature is greatly reduced, and the work environment of a cook is improved and protected; therefore, the recovered waste heat of the high temperature flue gas can be effectively and fully utilized, the energy waste is reduced, the considerable 'energy conservation and emission reduction' effects of waste heat recovery and utilization can be realized, and the energy accumulation device is accordance with the requirement of environmental protection.

Description

Technical field [0001] The invention relates to an energy gathering device, in particular to an energy gathering device for a flue gas waste heat tail pot in a commercial Chinese gas cooking stove. Background technique [0002] The smoke exhaust method of commercial Chinese gas cooking stoves in my country can be divided into two types: straight exhaust type and flue type. Only the flue-type structure is equipped with a flue gas waste heat tail pot, which is a custom configuration for all Chinese gang dishes in the traditional manufacturing of commercial kitchen frying stoves. The Guanggang is called "tailstock", while Shanghai, Jiangsu and Zhejiang are called "soup pots". Its main purpose is to meet the needs of chefs who can easily use the hot water or open cold water in the tail pot with a frying spoon at any time during the cooking process of Chinese food. [0003] The traditional blast-style Chinese gas cooking stove is a big energy consumer (the power is around 42-60kW). T...

Problems solved by technology

[0015] Because the tail pots used in cooking stoves in the past were all made of stainless steel stamped into a cylindrical container, and the heating area around and at the bottom was small, so it could not fully and effectively absorb the waste heat of high-temperature flue gas. This is a limited defect of simply absorbing heat on a plane , Even if the heat absorbed by the tail pot is calculated according to the new standard and 30% of the heat is included in the thermal efficiency calculation, the thermal efficiency is only increased by 1 to 2% at most
