Background
The heat exchanger is an important part of the hot blast stove, most of the existing hot blast stove heat exchangers are fixed tube plate type heat exchangers, the fixed tube plate type heat exchangers of the hot blast stove are provided with a front tube plate and a rear tube plate which are parallel to each other, corresponding tube holes are uniformly distributed on the front tube plate and the rear tube plate, tubes are connected between the corresponding tube holes, and the front tube plate and the rear tube plate of the heat exchanger are connected on a stove body of the hot blast stove in a positioning way. When the heat exchanger is used, high-temperature flue gas enters the tubes from one end of the tube at the front tube plate and flows out from one end of the tube behind the rear tube plate, and air flows between the tubes of the heat exchanger to heat the air.
The traditional heat exchanger tube bundle adopts a high-temperature resistant tube, and because the high-temperature flue gas is gradually cooled after heat exchange, the tube bundle is divided into a plurality of temperature intervals which can be sequentially arranged into a high-temperature area, a secondary high-temperature area and a medium-low temperature area. However, the existing plate heat exchanger has limited installation space, so the gas flow time is short, and the heat exchange effect is not ideal, so a large-scale biomass hot blast stove heat exchanger is provided.
The tube bundle of the utility model only adopts Q235A, and the material property can adapt to each temperature zone. Furthermore, the utility model discloses a heat transfer cold wind flows for "becomingto" flow to, and each heat exchange tube has three to have cubic cold wind to pass through the flow time and the route through increasing gas for the air current has realized the fluid heat exchange route of the efficiency of transferring heat the most, has improved the heat transfer ratio.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a large-scale living beings hot-blast furnace heat exchanger, which aims at the current situation of the prior art and provides the defects existing in the prior art.
In order to realize the purpose, the utility model discloses specifically adopt following technical scheme:
