Abstract
The utility model provides a novel spiral baffle heat exchanger and the new structure of the novel spiral baffle heat exchanger. The utility model also relates to a novel row pipe type cool exchanging device which adopts the structure of a spiral baffle. The utility model is characterized in that a shell is provided with a double shell pass; the width of the straight side of each baffle of a row pipe type heat exchanger which adopts the structure of a spiral baffle is increased by the distance of one row of pipes or two rows of pipes; compared with spiral baffle heat exchangers of other forms, the heat exchanger of the structure has high heat exchange efficiency and compact structure.
Description
(1) technical field
The utility model relates to the shell-and-tube spiral baffle heat exchanger in the industry technological processes such as oil, chemical industry, generating, metallurgy, food, pharmacy.
(2) background technology
Industry such as petrochemical industry begins to adopt the shell-and-tube spiral baffle heat exchanger in recent years.Spiral baffle heat exchanger shell side flow pattern is neither the longitudinal stream that vertically bends cross-current that plate forms, neither rod baffle forms, but a kind of spiral flow that moves around housing shaft cartridge eddy flow according to helical curve, this flow pattern has avoided the big pressure of the vertical duction that the vertical bow template type of flow brings to fall and triangle stagnant area (see figure 1), thereby improved flow velocity, made full use of heat exchange area, therefore, reached the raising heat exchange efficiency, reduce pressure and fall, reduced fouling and sediment alluvial effect.But present spiral baffle heat exchanger is only limited to the monoshell journey, has therefore influenced the scope of application of heat exchanger different flow.Simultaneously, two deflection plate straight flanges of spiral baffle heat exchanger only are simple butt joints at present, the easy short circuit of medium, and structure is not compact.(Fig. 2)
(3) summary of the invention
The utility model purpose is to improve the weakness of above-mentioned heat exchanger and the heat exchanger of a kind of novel employing helical baffles structure that proposes and its different structure, the particularly new construction that proposes at the EL99241930.1 utility model patent.
1, former spiral baffle heat exchanger is designed to the monoshell journey, and in the embodiment shown in fig. 3, the utility model is the bivalve journey that (1), (2) parts are formed.Change the bivalve journey into and can reduce flow area, increase the shell side velocity of medium, improve heat exchange efficiency.
2, former spiral baffle heat exchanger deflection plate is projected as the fanning strip (integers of 1≤x≤16) of 360 °/x, every fanning strip and housing axis have angle, adjacent two fanning strip straight flanges continue with simple docking mode, make and form approximate helical duct in the housing, this simple docking mode, straight flange zone at two adjacent fan plates easily produces short circuit, is easy to generate the tube bank radial separation during assembling.In the embodiment shown in fig. 4 former segmental baffle structure is widened one respectively in the straight flange both sides and drain into two comb distances, the straight flange of adjacent two fanning strips continues with intersection overlapping overlapping mode.This cross-lapping mode continues, and can reduce the short circuit phenomenon in two adjacent fanning strip straight flange zones, has strengthened the continuity of deflection plate simultaneously, the radial separation when having avoided assembling.

(5) specific embodiments
The technical solution of the utility model is provided by following enforcement:
1, journey structure in bivalve is to increase the long cylinder (2) of a diameter less than housing in housing (1) in the tube bank, the cylinder front end has a vertical barrel to work the toroidal membrane (3) of isolating medium earial drainage effect between journey, the annulus width is a distance between housing and the inner core, medium is entered behind the shell side by this dividing plate guiding inner core (2) by connecting pipe of shell (4), flow out the back flows to anterior dividing plate place between inner core and shell discharge connection (5) by the inner core terminal, the interior and outer spiral baffling form that should adopt segmental baffle (6) to form of cylinder of cylinder.
2, one of helical baffles all spirals still are made of continuously X piece deflection plate, but each piece deflection plate straight flange increases by one to two comb apart from width.Width b looks the device diameters size and determines.The overlapping overlap is interfered for avoiding contact point by passing with the root pipe during assembling, opens one at infall and intersects the breach of width so that insert.
Claims (2)
1, adopts a kind of novel heat exchanger of helical baffles structure, it is characterized in that housing is the bivalve journey.
2, a kind of novel heat exchanger according to claim 1 is characterized in that adopting every deflection plate straight flange of tubular heat exchanger of helical baffles structure to increase by one to two comb apart from width.
