Description

Hot galvanizing waste heat recovery device Technical Field The utility model relates to the technical field of galvanization equipment, in particular to a hot galvanizing waste heat recovery device. Background In conventional hot dip galvanizing production, high temperature fumes from the zinc bath are typically vented directly to the atmosphere. The flue gas has higher temperature, carries a large amount of heat energy, and directly discharges the flue gas not only causes the waste of energy, but also causes heat pollution to the environment. Through retrieving, chinese patent publication No. CN222007975U discloses a hot galvanizing waste heat recovery device, including the galvanized bath main part, fixed extension board is installed to galvanized bath main part one end, install multistage hydraulic cylinder on the fixed extension board, install the lift roof on multistage hydraulic cylinder's the flexible end, it is connected with hollow bull stick to rotate on the lift roof, hollow bull stick bottom intercommunication has the wind scooper, the rotation joint is installed on hollow bull stick top, install the air exhauster on the lift roof. The device realizes the recovery of hot flue gas through the collection fan housing, because its area is less, and the heat can't be collected completely, and it is unavoidable that there is some flue gas unable to be collected to cause the heat to run off, there is the improvement space. Disclosure of utility model The utility model aims to provide a hot galvanizing waste heat recovery device so as to solve the problems in the background technology. The hot galvanizing waste heat recovery device comprises a surrounding cover, wherein a recovery assembly is arranged outside the surrounding cover, the recovery assembly comprises an air suction fan fixedly arranged in the middle of the outer wall of one side of the surrounding cover, the air suction fan is communicated with the inner space of the surrounding cover, a tubular flue gas heat exchanger is fixedly arranged on the outer wall of the top of the surrounding cover, a first connecting pipe is fixedly inserted between the air suction fan and the tubular flue gas heat exchanger, a second connecting pipe is fixedly inserted on the outer wall of one side of the tubular flue gas heat exchanger, two air ejector pipes which are vertically arranged are rotatably connected inside the surrounding cover, and the two air ejector pipes are rotatably connected inside the second connecting pipe. The heat that can produce the galvanizing bath carries out comprehensive recovery to the air current circulates in enclosing the cover inside all the time, effectively avoids the outside loss of heat, is favorable to improving recovery effect, starts the air extraction fan in enclosing the cover outside, and the air extraction fan outwards takes out the inside air of enclosing the cover, and hot flue gas then gets into tubular flue gas heat exchanger through connecting pipe once, and heat wherein then can be absorbed, then gets into two jet pipes respectively through the connecting pipe, then get back to the enclosing cover inside through the nozzle of jet pipe, and the air current of production also can drive hot flue gas and in time be taken out by the air extraction fan, avoids the detention time to cause natural loss.
