Description
Technical field
The utility model belongs to roaster technical field, relates in particular to monolithic devices helical finned tube type heat exchanger for a kind of roaster.
Background technology
Alumina roasting furnace heat exchanger is one of key equipment of domestic large-scale aluminium manufacture enterprise.Its alumina producer roaster cooler need to exchange enough heat exchange amounts, meet the heat-shift of the cooling needs of aluminium powder, in general roaster cooler, be to adopt light pipe tube connector, by heat exchanger end connector, pipe is coupled together, tube interior carrys out cooling aluminium powder by water, the temperature of aluminium powder is reduced in certain temperature range simultaneously, water in cooler is taken away the heat of aluminium powder, can be used, both cooling like this aluminium powder, being used after the heat absorption of aluminium powder, save the energy again, improve the efficiency of enterprise.Yet for existing roaster cooler, after general existence pipe row uses a period of time, exchange capability of heat is poor, cause the drop temperature of aluminium powder can not meet the requirements of temperature, simultaneously in order to reduce as much as possible the volume of roaster cooler, reduce investment amount, pipe is arranged and put is all tight as much as possible, can cause like this aluminium powder to stop up and the low problem of percent of pass; Light pipe in roaster heat exchanger, owing to arranging that closely washing away of aluminium powder can cause tube wear very fast in the process of using, is changed frequently in addition, reduces the benefit of enterprise.
Utility model content
The utility model is in order to solve weak point of the prior art, provides that a kind of abrasionproof is effective, heat exchange efficiency is high, monolithic devices helical finned tube type heat exchanger for not susceptible to plugging roaster.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: monolithic devices helical finned tube type heat exchanger for roaster, comprise housing and the casing that is located at housing one end, in casing, be provided with casing is separated into into the dividing plate of water chamber and water outlet chamber, in housing, be provided with sealing gripper shoe, one group of water inlet spiral fin coil and one group of water outlet spiral fin coil, sealing gripper shoe is separated into heat exchange chamber and airtight chamber by housing, water inlet spiral fin coil and water outlet spiral fin coil are arranged in parallel and to be positioned at heat exchanging chamber indoor, it is indoor that one end of water inlet spiral fin coil and water outlet spiral fin coil extend into water inlet chamber and the water chamber of casing through housing respectively, the vertical sealing gripper shoe of passing of the other end of water inlet spiral fin coil and water outlet spiral fin coil extend in airtight chamber, in airtight chamber, be provided with the U-shaped light pipe being connected respectively into water spiral fin coil and water outlet spiral fin coil.
In described housing, be provided with bracing frame, every water inlet spiral fin coil and water outlet spiral fin coil are all located on bracing frame by pipe clamp or sleeve ring.
Described casing is provided with water inlet tube connector and the water outlet tube connector being communicated with water inlet chamber and water outlet chamber respectively.
Adopt technique scheme, the indoor aluminium powder passing through of heat exchanging chamber carries out heat exchange with water inlet spiral fin coil and water outlet spiral fin coil respectively, and the U-shaped light pipe in airtight chamber does not participate in heat exchange.The utility model is in the situation that original heat exchanger volume is constant, original number of tubes is reduced by half and can avoid like this obstruction of aluminium powder, the flow velocity of aluminium powder can lower approximately 80% simultaneously, reduce the wearing and tearing of aluminium powder to finned tube, and because monolithic devices spiral fin coil is manufactured by roll extrusion technology, root transition is round and smooth, there is fin simultaneously, therefore abrasionproof is effective, stronger from clear powder ability, good effect of heat exchange, the use of sealing gripper shoe can be kept apart the U-shaped light pipe that is easy to wearing and tearing, can extend the service life of heat exchanger.Pipe clamp or sleeve ring adopt steel plate to make, and bracing frame plays the effect of supporting water inlet spiral fin coil and water outlet spiral fin coil.
The utility model is reasonable in design, simple in structure, is applied in alumina roasting furnace and carries out heat exchange, can greatly improve heat exchange efficiency, and aluminium powder is difficult for stopping up, and wearability is stronger, thereby extends the service life of whole heat exchanger.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, monolithic devices helical finned tube type heat exchanger for roaster of the present utility model, comprise housing 1 and the casing 2 that is located at housing 1 one end, in casing 2, be provided with casing 2 is separated into into the dividing plate 5 of water chamber 3 and water outlet chamber 4, in housing 1, be provided with sealing gripper shoe 6, one group of water inlet spiral fin coil 7 and one group of water outlet spiral fin coil 8, sealing gripper shoe 6 is separated into heat exchange chamber 9 and airtight chamber 10 by housing 1, water inlet spiral fin coil 7 and water outlet spiral fin coil 8 are arranged in parallel and are positioned at heat exchange chamber 9, one end of water inlet spiral fin coil 7 and water outlet spiral fin coil 8 extend in the water inlet chamber 3 and water outlet chamber 4 of casing 2 through housing 1 respectively, the vertical sealing gripper shoe 6 of passing of the other end of water inlet spiral fin coil 7 and water outlet spiral fin coil 8 extend in airtight chamber 10, in airtight chamber 10, be provided with the U-shaped light pipe 11 being connected respectively into water spiral fin coil 7 and water outlet spiral fin coil 8.
