Description
Technical Field
The utility model relates to a heat accumulation formula environment-friendly stainless steel pipe annealing furnace.
Background
After the whitened stainless steel pipe is treated by the heat accumulating type annealing furnace, the whitened stainless steel pipe also needs to enter a whitening chamber for spray whitening treatment, at present, manufacturers generally arrange the whitening chamber at the outlet of the annealing furnace, and the annealing furnace and the whitening chamber are connected through a guide rail; in order to prevent water vapor from entering the annealing furnace, a certain distance needs to be kept between the annealing furnace and the whitening chamber, so that a large amount of waste heat at a furnace mouth of the annealing furnace cannot be effectively utilized and directly scattered to a workshop; in the whitening treatment process, the spraying water needs to be preheated, and if the waste heat of the furnace mouth of the annealing furnace is used for preheating the spraying water, the energy consumption of steel pipe manufacturers can be effectively reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a heat accumulating type environment-friendly stainless steel tube annealing furnace.
The technical scheme of the utility model is that: a heat accumulating type environment-friendly stainless steel tube annealing furnace comprises an annealing furnace and a steel tube whitening chamber arranged at the outlet of the annealing furnace, wherein the annealing furnace and the steel tube whitening chamber are connected through a guide rail, a waste heat recovery device is arranged between the annealing furnace and the steel tube whitening chamber and consists of a water storage tank and a secondary heat exchange cover which are arranged at the top of the annealing furnace, one end of the secondary heat exchange cover is connected with the upper part of the outlet of the annealing furnace, the other end of the secondary heat exchange cover is bent and fixed above the inlet of the steel tube whitening chamber, two sides of the secondary heat exchange cover are respectively provided with a side plate, the two side plates are arranged at two sides between the outlet of the annealing furnace and the inlet of the steel tube whitening chamber, an interlayer is also arranged inside the secondary heat exchange cover, the water storage tank is communicated with the interlayer through a water pipe, and the, the water storage tank is also connected with an air duct, one end of the air duct is positioned at the bottom in the water storage tank and is provided with a check valve, the other end of the air duct penetrates through the heat exchange cover and is fixed below the heat exchange cover, and the water storage tank is also provided with an exhaust pipe.
Furthermore, a support frame is respectively arranged at the outlet of the annealing furnace and the inlet of the steel pipe whitening chamber, and the secondary heat exchange cover, the side plate and the air guide pipe are fixed with the support frames.
Furthermore, a valve is arranged on a water pipe between the water storage tank and the secondary heat exchange cover.
The utility model has the advantages that: the utility model discloses to annealing furnace fire door's waste heat utilization divide two stages, first stage, the high temperature gas of fire door department passes through the air duct and gets into the tank, and the tip that the air duct is located the tank is equipped with the check valve, prevents the flowing backward of water, and the high temperature gas is discharged after directly carrying out the heat exchange with the water in the tank, and the water in the tank obtains certain intensification; in the second stage, water in the water storage tank reaches a spraying system of the whitening chamber through the secondary heat exchange cover, high-temperature gas at the furnace mouth exchanges heat with the secondary heat exchange cover, and meanwhile, the two side plates and the secondary heat exchange cover form a relatively closed channel between the annealing furnace and the whitening chamber, so that waste heat is prevented from overflowing, and the water in the secondary heat exchange cover is rapidly heated; therefore, the waste heat at the fire hole of the annealing furnace can be effectively utilized.
