Abstract
The utility model discloses a high-efficiency lamella heat exchanger. The high-efficiency lamella heat exchanger comprises a shell body installed on a support, lamella pass medium inlet-and-outlet connecting pipes and a shell pass medium inlet-and-outlet connecting pipe, wherein a lamella bundle assembly is arranged in the shell body. The high-efficiency lamella heat exchanger is characterized in that the lamella bundle assembly is formed by lamella sets in the mode that the lamella sets are tightly clamped by clamping plates and clamping bolts, the lamella sets are formed by lamellas in a staggered welding mode, semi-cylindrical pipe boxes are welded to the two ends of the lamella bundle assembly respectively, an expansion joint is communicated with each lamella pass medium inlet-and-outlet connecting pipe, transverse baffle plates and longitudinal short-circuit preventing plates are arranged on a lamella bundle pressing plate, and the lower end of the lamella bundle assembly is fixed to the shell body through an inner support. According to the high-efficiency lamella heat exchanger, due to the fact that the baffle plates and the short-circuit preventing plates are arranged on the lamella bundle pressing plate to form a baffling space, the section of the shell body is made full use of, the compactness of the high-efficiency lamella heat exchanger is improved, flow resistance of shell pass media is reduced, manufacturing cost of the high-efficiency lamella heat exchanger can be reduced, power consumption of the shell pass media can be reduced, and the purpose of saving energy can be achieved.
Description
Technical field
The utility model belongs to heat transmission equipment, particularly shell-and-plate heat transmission equipment.
Background technology
Lamella heat exchanger is the novel heat-exchange apparatus occurring in recent years, lamella heat exchanger had both had that heat transfer efficiency is high, compact conformation, lightweight advantage, inherit again shell-and-tube heat exchanger and held high pressure, high temperature resistant, good seal performance and the advantage such as safe and reliable, in every profession and trade, promote the use of at present, particularly in oil refining industry, use more.
Current lamella heat exchanger is all got one's things ready and is formed in circular shell by square plate; Existing lamella heat exchanger shell side medium channel has two kinds of forms: a kind of is once-through type, and structure is, at plate bundle, square casing is set outward, and shell side medium is limited in streamlined flow in square casing; An airtight baffling type, structure is, at plate bundle, Long Circle housing is set outward, shell side medium is limited in baffling in Long Circle housing; The former is subject to structural limitations, and the space availability ratio of circular shell is very little, not only wastes case material but also make the resistance of shell side medium large, although the latter's structure is baffling, but not only the space of circular shell does not make full use of, can make on the contrary the enlarged diameter of housing, cause the waste of material.
Utility model content
In order to overcome the drawback existing in existing lamella heat exchanger structure, the purpose of this utility model is to provide a kind of new and effective lamella heat exchanger,
The utility model solves the technical scheme that its technical problem adopts: a kind of efficient plate shell type heat exchanger, comprise the housing being arranged on bearing, plate journey medium is imported and exported and is taken over, shell side medium inlet/outlet pipe, in its housing, be provided with plate tread assembly, it is characterized in that: described plate tread assembly forms by the staggered plate groups being welded to form of plate and by clamping plate and fishbolt clamping, plate tread assembly two ends welding semicircular cylinder build bobbin carriage, by expansion joint and plate journey medium, imported and exported to take over respectively again and be connected, the at least horizontal deflection plate of twice is set on described pressure strip, pressure strip center arranges anti-short board longitudinally, plate tread assembly lower end is fixed on housing by interior bearing.
Shell side between described housing and plate tread assembly is baffling structure, is transversely welded with deflection plate, is welded with anti-short board, any two deflection plates and anti-short board composition baffling space on longitudinally at clamping plate.
Described fishbolt arranges sleeve pipe outward, and at sleeve pipe middle part, an expansion loop is set.
Described housing is provided with vessel flange, is removable structure.
Hermetically-sealed construction with housing is set on described anti-short board, described hermetically-sealed construction comprises and is positioned at the arc-shaped spring piece of anti-short board both sides and by arc-shaped spring piece one end and the fixing set bolt of anti-short board, the other end of arc-shaped spring piece and shell inner surface rely on elastic compression sealing.
Described interior support style is ear seat, ring support or girth sheets.
The clamping mode of described plate groups can adopt fishbolt mode or round steel and clamping plate welding manner.
Deflection plate is set on clamping plate for the passing through of the lamella heat exchanger that the utility model provides and anti-short board forms baffling space, make full use of housing cross section, the compactness that has improved heat exchanger has reduced again the flow resistance of shell side medium, both can reduce the cost of heat exchanger, can reduce the power consumption of shell side medium again, to reach energy-conservation object.
Owing at fishbolt, sleeve pipe being set outward, and expansion loop is set on sleeve pipe, the making frock of being convenient to heat exchanger is carried out the water pressure test of plate bundle.
Owing to being provided with vessel flange on housing, be removable structure, be easy to the extraction maintenance of heat exchanger plates bundle.
Lamella heat exchanger is optimized structure, deflection plate and anti-short board are set on plate bundle clamping plate, any two deflection plates and anti-short board form baffling space, this baffling space takes full advantage of the cross section of circular cylinder body, improved the compactness of heat exchanger, under the condition of identical casings diameter, the baffling space sectional area of shell side medium is greater than other arbitrary structures, shell side medium greatly reduces flow velocity when this kind of baffling spatial flow, has reduced greatly again the local resistance that medium causes due to baffling.
