Abstract
The utility model relates to a novel sleeve type heat exchanger, which comprises a plurality of rows of sleeve type heat exchange tubes. Each row is provided with two heat exchange tubes; each heat exchange tube includes an inner tube and an outer tube; each inner tube penetrates through the corresponding outer tube; each inner tube and the corresponding outer tube are welded by an oval seal head at one end of each heat exchange tube; and a positioning block is arranged between the inner tube and the outer tube at the other end of each heat exchange tube. Using the experience of the design concept of a floating head heat exchanger, the novel sleeve type heat exchanger has the advantages that an inner and outer tube structure with two fixedly connected ends is changed into a structure with one fixed end and the other end added with a jacket tube box and a positioning block outside each inner tube, the space for free extension and retraction of the heat exchange tubes is reserved so that the purpose of relieving temperature difference stress is achieved, and welded joint tearing caused by temperature difference stress build-up is prevented.
Description
Technical field
The utility model relates to a kind of cooling heat exchanger, specifically relates to a kind of new casing formula heat transmission equipment.
Background technology
In the prior art, casing type heat exchanging equipment, as illustrated in fig. 1 and 2, and pipe and outer tube two parts in generally being divided into, interior pipe feeds high temperature medium to be cooled, and interior pipe mean wall temperature is 125 ℃, and outer tube feeds recirculated water cooling medium, and the outer tube mean wall temperature is 37 ℃.Interior pipe passes outer tube, realizes the inner and outer pipe exchange heat, and weld with ellipse head and interior pipe the outer tube end.This structure is in the production use, because of interior pipe temperature higher, the thermal (temperature difference) stress that Yin Wendu produces in equipment operation running is very big, because of two ends about on the structure are completely fixed in aggregates, interior pipe does not have the space of freely stretching, cause thermal (temperature difference) stress not alleviate, when thermal (temperature difference) stress accumulates to certain degree, the inner and outer pipe attachment weld will be torn destruction.
The utility model content
The deficiency that design exists at prior art middle sleeve formula heat transmission equipment, the purpose of this utility model are to provide a kind of thermal (temperature difference) stress of can alleviating to assemble, and prevent that weld seam is torn the new casing formula heat transmission equipment of destruction.
The technical scheme that the utility model adopted is:
New casing formula heat transmission equipment comprises many bar casing tubes formula heat exchanger tube, and every row is provided with two heat exchanger tubes, pipe and outer tube in heat exchanger tube is divided into, interior pipe passes outer tube, and an end end of heat exchanger tube adopts ellipse head with interior pipe and outer tube welding, and the end of the other end is provided with locating piece between interior pipe and outer tube.
Be provided with an end of locating piece, adopting 180 ° of elbows that the interior pipe of two heat exchanger tubes is connected, and be provided with a jacket type bobbin carriage, connecting by connecting plate between jacket type bobbin carriage and interior pipe, the outer tube.
Be provided with an end of ellipse head, adopting 180 ° of elbows that the interior pipe of two heat exchanger tubes is connected with upper and lower row's interior pipe respectively.
Compare with casing type heat exchanging equipment of the prior art, advantage of the present utility model is,
For alleviating thermal (temperature difference) stress, use for reference the design concept of movable tube sheets heat exchanger, allow the fixedly connected inner and outer pipe structure in two ends, changing to an end fixes, the other end increases a jacket type bobbin carriage outside interior pipe, and locating piece, has kept the space that heat exchanger tube freely stretches, to reach the purpose of alleviating thermal (temperature difference) stress, prevented to assemble the appearance that the weld seam that is caused is torn situation because of thermal (temperature difference) stress.

The specific embodiment
For the ease of it will be appreciated by those skilled in the art that utility model is further described below in conjunction with accompanying drawing.
As shown in Figure 3, new casing formula heat transmission equipment comprises many bar casing tubes formula heat exchanger tube, and every row is provided with two heat exchanger tubes, and steam enters the interior pipe 2 of heat transmission equipment by import 6, leaves from exporting 7; Cooling water enters the outer tube 1 of heat transmission equipment from import 9, leaves from exporting 8.
As shown in Figure 4, pipe 2 and outer tube 1 in every heat exchanger tube is divided into, interior pipe 2 passes outer tube 1, and an end end of heat exchanger tube adopts ellipse head 3 with interior pipe 2 and outer tube 1 welding, and the end of the other end is provided with locating piece 5 between interior pipe 2 and outer tube 1.
Be provided with an end of locating piece 5, adopting 180 ° of elbows that the interior pipe 2 of two heat exchanger tubes is connected, and be provided with a jacket type bobbin carriage 4, connecting by connecting plate 10 between jacket type bobbin carriage 4 and interior pipe 2, the outer tube 1.So both play fixation, and made outer tube 1 and jacket type bobbin carriage 4 become a unified integral body again, formed new heat exchange " shell side ".
Be provided with an end of ellipse head, adopting 180 ° of elbows that the interior pipe of two heat exchanger tubes is connected with upper and lower row's interior pipe respectively.Each row's structure is identical, thereby forms the new casing formula heat transmission equipment with many row's structures.
