Its advantages are novel design, reasonable structure, easy shaping and making, high compactness and high strength. The heat exchanger built by the heat exchanger has good air tightness, obviously reduced air leakage rate and high air preheating temperature, thereby achieving the purposes of quick heating of the furnace, high yield and low energy consumption. The utility model can be widely used for heat exchange systems of various heating furnaces and soaking furnaces.
Description
The utility model relates to a kind of heat exchanger tube that is widely used in heating furnace and soaking pit heat exchanger, belongs to the universal component of heat exchange.
At present, generally heat the soaking pit that steel ingot is used, generally use the potter's clay heat exchanger to give hot-air, recycle fume afterheat, energy savings.Common potter's clay heat exchanger mostly is that to adopt length be that 387 millimeters potter's clay pipe brick and brick the building of terminal board forms.Pipe brick and terminal board brick are all the monomer brick, and during building construction, every pipe brick two ends are connected with the terminal board brick, that is alternately between per two pipe bricks build a terminal board brick by laying bricks or stones, fill out envelope with refractory wass.The heat exchanger that is built into like this, there are two seams in the two ends of every pipe brick, because that mud is filled out envelope is not full, sealing is poor, is the main cause that causes the serious gas leakage of heat exchanger.
Building by laying bricks or stones of the junction of pipe brick and its lower end terminal board brick (usually cry down seam), by the natural densification mud of pipe brick own wt, and mud fills easily, so descend the joint seal better performances.But building by laying bricks or stones of the junction (calling seam usually) of pipe brick and its upper end terminal board brick is just very difficult, owing to mud often is not easy to fill up, so go up the joint seal poor-performing.In use, manage the higher air of outer normal pressure just in these seams are bled the lower pipe of negative pressure in the flue gas, because pressure reduction is bigger, a large amount of leakages of air not only cause a series of adverse effect to stove thermal technology work, and make flue gas dilution, flue-gas temperature reduces,, cause air to give hot temperature and reduce, finally cause reduction of heating furnace output and burnup to increase.
The purpose of this utility model is at above-mentioned weak point of the prior art, and a kind of coiled heat-exchange ceramic pipe with integral seamless structure is provided.
The utility model is made up of a pipe and regular polygon or rectangle joint dish two parts.During making, design a mold, pug after calendering is packed in the die sleeve, adopt up and down that two-sided extruding one-shot forming is jointless overall structure pipe dish heat-exchange ceramic base, after burn till and be goods by the planform of heat exchanger tube.
The utility model coiled heat-exchange ceramic pipe with integral seamless structure, when building the construction of heating furnace or soaking pit heat exchanger by laying bricks or stones, one end of terminal board should be made progress, an end of pipe mouth is downward, and the pipe mouth embeds in the annular groove of terminal board, above terminal board, fill refractory wass, the following seam of pipe mouth and terminal board by heat exchanger tube own wt nature densification mud, reaches full state, favorable sealing property, this has just solved the gas leakage problem of heat exchanger substantially.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the cutaway view of middle lower floor coiled heat-exchange ceramic pipe with integral seamless structure;
Fig. 2 is the vertical view of middle lower floor coiled heat-exchange ceramic pipe with integral seamless structure;
Fig. 3 is the cutaway view of upper strata coiled heat-exchange ceramic pipe with integral seamless structure;
Fig. 4 is the vertical view of upper strata coiled heat-exchange ceramic pipe with integral seamless structure;
Description of drawings:
1. pipe, 2. terminal board, 3. deep-slotted chip breaker, 4. annular groove.
The utility model coiled heat-exchange ceramic pipe with integral seamless structure is made up of pipe ［ 1 ］ and terminal board ［ 2 ］ two parts, pipe ［ 1 ］ and terminal board ［ 2 ］ be by pug through die sleeve up and down two-sided extruding one-shot forming be that jointless pipe is checked and regulated body structure.As shown in Figure 1, 2, pipe ［ 1 ］ is last thick thin down rounding Taper Pipe, terminal board ［ 2 ］ has the disk ring of the octagon of deep-slotted chip breaker ［ 3 ］ for the middle part, neighboring, one annular groove ［ 4 ］ is arranged at the top of disk ring, its ring external diameter is slightly larger than the external diameter of pipe ［ 1 ］ end opening, so that when building by laying bricks or stones, the pipe mouth embeds in the groove ［ 4 ］.Pipe ［ 1 ］ is identical with the diameter of bore size of terminal board ［ 2 ］, is communicated with up and down.The neighboring of pipe ［ 1 ］ and terminal board ［ 2 ］ junction is an arc chord angle, and this can increase the intensity of pipe and terminal board junction.
Fig. 3,4 is depicted as the upper strata coiled heat-exchange ceramic pipe with integral seamless structure, difference with the middle lower floor coiled heat-exchange ceramic pipe with integral seamless structure shown in Fig. 1,2, the top that only is terminal board ［ 2 ］ disk ring does not have annular groove, pipe ［ 1 ］ is identical with the diameter of bore of terminal board ［ 2 ］, up/down perforation, all the other planforms are identical.Common heating furnace ceramic heat exchanger is built into by six layers of heat exchanger tube, during building construction, upper strata coiled heat-exchange ceramic pipe with integral seamless structure shown in Fig. 3,4 is built in the superiors, and the middle lower floor coiled heat-exchange ceramic pipe with integral seamless structure shown in Fig. 1,2 is built at all the other each layers.
The utility model compared with prior art its advantage is that pipe and terminal board are seamless integral body, and modern design is rational in infrastructure, is easy to moulding and makes, and compactness is good, and intensity is big. With its Heat Exchanger for Reheating Furnace of building by laying bricks or stones, air-tightness is good, and leak rate significantly descends, and the masonry globality is strong, strengthens heat transfer effect, and air gives hot temperature height. Thereby it is fast to reach the stove heating, the output height, and energy consumption is low.
The utility model can be widely used in building by laying bricks or stones the heat-exchange system of various heating furnaces and soaking pit.
