Description
Technical field
The utility model belongs to field of heat exchangers.In particular to one kind can be applied to petroleum, chemical industry, electric power, chemical fertilizer field
The spacing column support plate beam of gas-gas heat exchanger.
Background technique
Board-like gas-gas heat exchanger becomes current gas-gas heat exchange because of the features such as compact-sized, heat transfer efficiency is high, occupied area is small
The developing direction of device technology, presently used heat transfer element are corrugated plate dst plate and two kinds of plate plate.
The compacting of plate ripple needs large-scale molding machine, and fabrication cycle is long, and flow harden phenomenon is also easy to produce in punching course,
Decrease of fatigue strength is easy to produce fatigue fracture, causes to leak；Restriction of the plate ripple's depth by toughness of material, only relies on
Ripple mutually supports the cross section of fluid channel of the low pressure clean gas passages to be formed and the non-clean gas passages of the high pressure product amplitude of accommodation small；
Plate heat transfer effect is improved with the increase of plate ripple angle, but fluid resistance is consequently increased；By plate ripple struction
The limitation non-clean gas passages of high pressure are easy to produce dust stratification clogging.
Plate plate droop loss is small, but bearing capacity is poor, to keep channel shape, need to be supported using support component；
Support component is mostly steel bar, rod iron or corrugated plating, and gas flow is consistent with support direction, it can be achieved that single process, more folding journeys without
Method is realized.
Utility model content
The utility model provides a kind of gas-gas heat exchanger spacing column support plate beam, with compact-sized, pressure drop is low, sealing
Performance is good, is not easy the advantages of dust stratification.
The technical solution of the utility model is:
A kind of spacing column support plate beam, including heat transferring plate, two heat transferring plate make-ups form an independent plate pipe, internal
Uniformly fixed spacing column, the periphery setting strip of paper used for sealing in addition to inlet and outlet form the plate pipe in low pressure purge gas flow channel；The plate pipe
Contactless between adjacent panels pipe when stacking, strip of paper used for sealing is arranged in the periphery in addition to inlet and outlet, forms the non-clean gas of high pressure independent
The rectangular channel of body flow channel, mesolow purge gas flow channel are alternateed with the non-purge gas flow channel of high pressure
And form spacing column support plate beam.
Low pressure purge gas flow channel import and export is provided with baffle plate.
Flow deflector is set between the baffle plate.
The positive effect of the utility model is:
1, for spacing column support plate Shu Caiyong plate as heat transfer element, sheet surface is smooth and without flow dead zone, soot blowing side
Just, fluid dust stratification blockage problem is solved.
2, spacing column support plate beam can pass through spacing column height adjustment low pressure clean gas runner, the non-clean gas stream of high pressure
Road side uses non-contact structure, and channel height adjusts height by strip of paper used for sealing, avoids the probability of the non-clean gas passages blocking of high pressure.
3, low pressure clean gas runner height and the non-clean gas runner height of high pressure, Proper Match are adjusted using spacing column
Media of both sides pressure drop.
4, weldering is all made of between spacing column support plate beam module and at low pressure clean gas and the non-clean gas point journey of high pressure
It connects or other forms sealing structure, string leakage between isolation low pressure clean gas and the non-clean gas of high pressure, the thorough gas gas that solves changes
Hot device Air Leakage.Equipment long-term operation is reliable, and O&M cost reduces.
The utility model be suitable for petroleum, chemical industry, electric power, chemical fertilizer field gas-gas heat exchanger.

Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
Referring to Fig.1,2, a kind of spacing column support plate beam, including heat transferring plate 1, spacing column 2, strip of paper used for sealing 3, flow deflector 4, baffling
Plate 5.Strip of paper used for sealing 3 is allowed to be formed enclosure space each other for separating cold and hot fluid runner.
Fig. 1 is low pressure clean gas, the non-clean gas of high pressure in the dynamic spacing column support plate beam of cross-current, and Fig. 2 is that low pressure is clean
Net gas, the non-clean gas of high pressure are in pure counter-current flow spacing column support plate beam.The present embodiment is with pure adverse current spacing column support plate
Beam is illustrated.Spacing column 2, strip of paper used for sealing 3, inlet and outlet welding flow deflector 4, baffle plate are successively welded between two heat transferring plates 1
5, an independent plate pipe is made, then another plate pipe is stacked at an upper portion thereof in plate pipe side spot welding strip of paper used for sealing 3, so repeats,
Form rectangular channel one by one, low pressure clean gas circulation passage (101 → 102) and the non-clean gas circulation passage (201 of high pressure
→ 202) it alternates, by the strip of paper used for sealing 3 and adjacent panels pipe welded seal between two plate pipes, spacing column support plate beam is integrally formed.It is low
