The utility model consists of a carbon black flue gas inlet box, a heat exchange section including a lower tube plate and an upper tube plate, a carbon black flue gas outlet box and a plurality of heat exchange tubes provided in the heat exchange section, wherein, both ends of each of the heat exchange tubes respectively penetrate the holes of the upper and lower tube plates, and a gas seal component is provided between the upper end of the heat exchange tube and the upper tube plate. The utility model has the advantages of simple structure, high temperature of air preheating, good effect of heat exchange and long service life.
Description
The utility model relates to a kind of preheater, particularly be the high-temperature air preheater that air themperature can be preheating to 800 ℃ of 700 ∽ that a kind of production of carbon black line is used.
Existing high-temperature air preheater comprises the carbon black smoke inlet box, contains the heat exchanging segment of lower perforated plate, upper perforated plate, the carbon black smoke EXPORT CARTON, and the many heat exchanger tubes in hole on the upper and lower tube sheet are passed at the two ends that are positioned at heat exchanging segment.Adopt welding or expanded joint between heat exchanger tube and upper perforated plate, equipment is in operation because of producing the fragile preheater of thermal (temperature difference) stress, reduces the service life of preheater.Housing compensator and single tube compensator, complex structure, cost height are housed on housing or pipeline simultaneously.
In view of above reason, the purpose of this utility model is in order to overcome above deficiency, to provide a kind of simple in structure, air preheating temperature height, good effect of heat exchange, the high-temperature air preheater of long service life.
The purpose of this utility model is achieved like this:
The utility model high-temperature air preheater comprises the carbon black smoke inlet box, the heat exchanging segment that contains lower perforated plate, upper perforated plate, the carbon black smoke EXPORT CARTON, in heat exchanging segment, there are many two ends to pass the heat exchanger tube that upper perforated plate hole, lower perforated plate hole communicate with carbon black smoke inlet box and carbon black smoke EXPORT CARTON respectively, deflection plate is arranged in the heat exchanging segment, between heat exchanger tube upper end and upper perforated plate, the hermetic seal assembly is arranged.
Above-mentioned hermetic seal assembly comprises and being contained in the tubesheet holes and upper perforated plate all-in-one-piece outer tube that the inner sleeve that is positioned at outer tube and heat exchanger tube all-in-one-piece and is slidingly matched with outer tube has airtight sealing groove on outer sleeve inner wall.
Groove is arranged at above-mentioned outer tube top, and dust retaining ring is housed in the groove, and the gland bottom is stretched in the overcoat tube seat and with connector gland is connected on the outer tube.
Above-mentioned heat exchanging segment is arranged in lower perforated plate top cover plate, a plurality of sleeve pipe that is sleeved on the heat exchanger tube and stretches into cover board hole, lower perforated plate hole that forms cooling air cooling lower perforated plate gas circuit with lower perforated plate, take over the cooling air inlet that cooling air cooling lower perforated plate gas circuit communicates, between sleeve pipe and sleeve pipe parting bead is arranged.
The housing inner return-air pipe that communicates with cooling air cooling lower perforated plate gas circuit is arranged in the above-mentioned heat exchanging segment.
Above-mentioned housing has the outer muffler of housing that two ends are taken over air intlet respectively, the cooling air inlet adapter is communicated with outward, has the cooling air outlet slit that communicates with cooling air cooling lower perforated plate gas circuit to take on housing.
Referring to Fig. 1 ∽ Fig. 4, the carbon black smoke entrance sleeve is connected with reacting furnace, the carbon black smoke discharge connection is connected with process pipe.During work, the high temperature carbon black smoke that the reacting furnace stay segment flows out is flowed in the case by the carbon black smoke entrance sleeve of carbon black smoke inlet box, and flow into respectively in the every heat exchanger tube, the heat that heat exchanger tube is derived is heated the flow air of turning back from the top down in the shell side gradually, makes air preheat.The carbon black smoke that flows from bottom to top in the heat exchanger tube is cooling gradually also, and the carbon black smoke that flows out from heat exchanger tube flows into process pipe by the carbon black smoke discharge connection of carbon black smoke EXPORT CARTON.Air intake machine air supplied divides two partly: main flow is partly taken over by the air intlet on heat exchanging segment top and is entered shell side, and it is mobile to turn back from the top down, and preheating flows into process pipe after the air outlet slit of heat exchanging segment bottom is taken over.Cooling blast by the cooling air inlet of heat exchanging segment bottom take over enter cooling lower perforated plate gas circuit lower perforated plate is cooled off after again through housing inner return-air pipe flow to heat exchanging segment top flow into primary air (or through the cooling air outlet slit take over flow into air intlet that the outer muffler of housing flows to heat exchanging segment top take in the inflow primary air).In the course of work, shell side, tube side operating temperature are different, material is different, when swell increment is different, because inner sleeve on the heat exchanger tube and the outer tube on the upper perforated plate are slidingly matched, heat exchanger tube can move freely in outer tube vertically, can not produce thermal (temperature difference) stress, so can not cause device damage.Meanwhile, owing to adopted the gas circuit of cooling lower perforated plate, guaranteed that the lower perforated plate temperature drops under the allowable work temperature, can not cause device damage.
The utility model high-temperature air preheater is used for production of carbon black line air preheating temperature height, reach 800 ℃ of 700 ∽, good effect of heat exchange, obvious energy conservation, different because of operating temperature each other, the different generation of swell increment the thermal (temperature difference) stresses with tube side of no shell side cause heat exchanging segment to damage factor, the service life of having improved equipment greatly.Simple in structure, cost is low.
