Heat recovery warming air intake and exhaust system

Abstract

The invention discloses a heat recovery warming air intake and exhaust system which comprises an exhaust hood, an exhaust duct, an exhaust fan, an lampblack purifier, an exhaust outlet, a fresh air duct, an induced draft fan and a fresh air inlet, wherein both the exhaust outlet and the fresh air inlet are provided with radiators and the two radiators are connected with a circulation pipe through a circulation water pump. The heat recovery warming air intake and exhaust system is simple in structure and easy to clean, is capable of effectively utilizing abundant heat in the kitchen fumes in winter and applying the heat to the air heating of an air intake, so that the temperature of the cold air entering into the kitchen rises to ensure that the temperature in the kitchen does not fall rapidly due to the entrance of the cold air. Through using antifreeze liquid as a radiator medium, the whole system is effectively ensured to run normally in winter; a thermal insulation layer is arranged outside the pipes of the system, so that the energy loss is effectively prevented, the residual heat energy is fully utilized and the function of saving energy and reducing emission is provided.

Description

technical field [0001] The invention relates to an air intake and exhaust system, in particular to an air intake and exhaust system for energy saving and emission reduction. Background technique [0002] As the pace of people's life is getting faster and faster, more and more people are saving time and energy in daily life by solving three meals a day in large canteens, restaurants, and catering centers. This has led to the rapid development of catering enterprises, and the scale is getting bigger and bigger. Due to the cooking characteristics of Chinese food, frying, frying and other methods are often used, so a lot of oily smoke will be generated. However, in a large kitchen, dozens of stoves are often operated together, so a lot of oily fume will be generated, so that the kitchen of a large enterprise must be ventilated in large quantities. A large amount of ventilation has caused the operating environment temperature of the kitchen to be affected by the external air te...

AI Technical Summary

Problems solved by technology

The heat recovery devices in the prior art are generally plate-fin or runner heat recovery devices. These devices have high cost, very short air intake and exhaust distances, poor anti-pollution ability during heat exchange, and are easily polluted by oil and inconvenient. Cleaning, and the air inlet and outlet are in one system, the structure is complex, the energy is not easy to control, and the environmental requirements are high, so it is not suitable for heat recovery in catering enterprises
