The utility model discloses the effect is obvious, and convenient to use can satisfy the interior temperature of annealing stove quench zone on the one hand and further descend fast, and on the other hand more makes coal gas preheating temperature improve, has improved the level of resources utilization, has practiced thrift the energy, has promoted the further improvement of production technology.
Description
Technical field
The utility model relates to a kind of Novel disk withdrawal stove, belongs to annealing furnace field, specifically a kind of pipeline heat exchange type annealing furnace.
Background technology
The gas preheating of traditional annealing furnace is the conversion by reversing valve, extract hot blast heating storage hot-bulb, then reversing valve commutation, coal gas is heated through storage hot-bulb, improve temperature at 100-200 DEG C by storage hot-bulb to coal gas, but vacuum fan can take a large amount of heat energy away simultaneously, make hot temperature in stove be pumped greatly, add energy consumption and again reduce in-furnace temperature and throughput, need again to increase high-power induced draft fan.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of pipeline heat exchange type annealing furnace, and annealing furnace quench zone exhaust heat can be utilized to heated by gas, it is to increase capacity usage ratio reduction.
In order to realize above-mentioned purpose, the technical solution adopted in the utility model is: a kind of pipeline heat exchange type annealing furnace, comprise slow cooling section, quench zone, soaking zone and heating zone, it is provided with arranged type water pipe in described quench zone upper space, and also it is provided with arranged type water back, described arranged type water back comprises inlet duct, circulating line and outlet conduit, and circulating line is evenly arranged in annealing furnace quench zone top.
Further, described circulating line comprises front heating zone, rear heat zone and connecting tube, described front heating zone and rear heat zone pipeline are U-shaped pipeline configuration, front heating zone joint access pipeline and connecting tube, rear heat zone connection outlet pipeline and connecting tube, adopt U-shape structure can increase heating-surface area, it is to increase resource utilization.
Preferably, described arranged type pipe material is the good metal material of resistance to compression and heat conduction.
Preferably, described arranged type pipeline is steel pipe, can bear bigger pressure, and heat transfer efficiencies height.
Preferably, described arranged type pipeline is copper pipe, can bear bigger pressure, and heat transfer efficiencies height.
Preferably, described arranged type pipeline is aluminum pipe, can bear bigger pressure, and heat transfer efficiencies height.
The beneficial effects of the utility model are: annealing furnace quench zone sets up gas line makes in-furnace temperature quickly fall to the temperature needed for production technique further, gas temperature is heated to again 400-450 DEG C simultaneously, both control furnace temperature and ensure cast tube annealing quality, again save a large amount of energy, substantially increase productivity, thoroughly overturn the production technique of traditional backwardness, made innovative technology displace tremendous potential, made equipment more perfect.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of pipeline heat exchange type annealing furnace, comprise slow cooling section 1, quench zone 2, soaking zone 3 and heating zone 4, it is provided with arranged type water pipe 22 in described quench zone 2 upper space, and also it is provided with arranged type water back 21, described arranged type water back 21 comprises inlet duct 211, and circulating line 213 and outlet conduit 212, circulating line 213 is evenly arranged in the top of annealing furnace quench zone 2.
Further, described circulating line 213 comprises front heating zone 214, rear heat zone 216 and connecting tube 215, described front heating zone 214 and rear heat zone 216 pipeline are U-shaped pipeline configuration, front heating zone 214 joint access pipeline 211 and connecting tube 215, rear heat zone 216 connection outlet pipeline 212 and connecting tube 215, adopt U-shape structure can increase heating-surface area, it is to increase resource utilization.
Preferably, described arranged type water back 21 material is the good metal material of resistance to compression and heat conduction.
Preferably, described arranged type water back 21 is steel pipe, can bear bigger pressure, and heat transfer efficiencies height.
Preferably, described arranged type water back 21 is copper pipe, can bear bigger pressure, and heat transfer efficiencies height.
Preferably, described arranged type water back 21 is aluminum pipe, can bear bigger pressure, and heat transfer efficiencies height.
Through practice, heat to coal gas with pipeline heat exchange type, namely arranged type water back 21 is installed in the quench zone 2 of annealing furnace, the heat energy of quench zone in stove is utilized to make coal gas intensification 400-450 DEG C, original design water pipe is lowered the temperature, cooling can not make the rapid drop in temperature of quench zone 2 in stove to processing requirement, after setting up heated by gas pipeline 21, in-furnace temperature is made to quickly fall to the temperature needed for production technique further, gas temperature is heated to again 400-450 DEG C simultaneously, namely control furnace temperature and ensure cast tube annealing quality, again save a large amount of energy, also substantially increase productivity, thoroughly overturn the production technique of traditional backwardness, innovative technology is made to displace tremendous potential, make equipment more perfect.
In sum, the utility model successful, it may also be useful to convenient, on the one hand can meet the further rapid decrease of temperature in annealing furnace quench zone, more make gas preheating temperature improve on the other hand, it is to increase the level of resources utilization, save the energy, promote the further raising of production technique.
