Description

Heat recovery device of hot stir-frying cooking bench Technical Field The utility model relates to the technical field of kitchen waste heat recovery and utilization, in particular to a heat recovery device of a hot frying cooking bench. Background With the increasing use of energy, the problem of effective utilization of energy is receiving more and more attention. At present, natural gas is widely used in places such as restaurants and canteen cooking in China, a large amount of high-temperature smoke is generated in the use process of the gas stove, the working principle is that the gas enters the stove from an air inlet pipe, enters a stove head through adjustment of a gas valve (the adjustment is carried out by a user through a knob), meanwhile, a part of air (the part of air is called primary air) is mixed, the mixed gas is sprayed out from a fire hole of a distributor and is ignited by an ignition device to form flames (the air required during combustion is called secondary air), the flames are used for heating a cooker arranged on a pot support, the cooker is exhausted through a smoke outlet after combustion, the temperature exhausted through the smoke outlet is about 140 ℃, a part of heat generated by the gas stove in the process is taken away by the smoke, so that great waste is caused, meanwhile, the temperature of the cooking place is increased, the temperature between hot stir-frying is usually more than 35 degrees, and the working environment is bad. Therefore, the heat in the flue gas is effectively recovered, so that the method is a better method for improving the energy utilization rate and can also reduce the temperature of a cooking place. The most common mode is to recycle the waste heat of the flue gas through the heat exchanger, so that other energy consumption can not be generated in the process, the environment is not polluted, the installation process is convenient, the occupied area is small, most of the waste heat of the flue gas is absorbed through other fluid in the heat exchanger, and then the waste heat is used in other places, thereby realizing the effective utilization of energy, and further improving the waste heat recycling efficiency. In the heat recovery to the flue gas, need come out the flue gas in the chimney, transfer the heat in the flue gas through heat exchanger and external medium, but operating time is long, and the flue gas circulation's of chimney and heat exchanger part all can the dust that can hardly avoid to collect in the soil for the water conservancy diversion effect to the flue gas worsens and even takes place to block up, and current heat recovery device is difficult to demolish because of the structure complicacy, makes the clearance become troublesome.
